Patent DE-3112950-A1 (DE)
Title: Protective fence for garden beds or garden installations against crawling pests
Inventor: DOERING ERICH
IPC: A01M23/38
Filed: 1981-03-31
Abstract: Protective fences for garden beds against crawling pests, especially slugs and snails, in the form of bent sheet-metal strips or of flat supports in the form of strips or plates, having two bare conductors which are insulated from one another and are laid horizontally at such a distance that they can be touched simultaneously by the pests, and which conductors are in each case connected to one pole of a low-voltage source, do not fulfil the hopes placed on them. A protective fence which can operate in a functionally reliable manner over relatively long times consists of supports in the form of plates and having two parallel bare conductors which are connected to a low-voltage source, in each case one projecting turned-down strip being fitted to the support above and below the conductors, of which turned-down strips, the upper preferably forms an acute angle with the support and the lower, especially inclined turned-down strip projects further than the upper turned-down strip. <IMAGE>

Abstract: Using a palladium catalyst in the presence of an oxyacetylating amount of oxygen, acetic anhydride and acetic acid, and carrying out the reaction at increased temperatures and pressures, phenyl acetate is converted mainly to acetoxyacetophenone. The product and isomer distribution depends on the optional use of an acetate of a metal of group IA or a mineral acid.
Patent DE-3115773-A1 (DE)
Title: Device for producing mouldings from foamable plastic particles
Inventor: ERLENBACH HANS
IPC: B29C33/10
Filed: 1981-04-18
Abstract: In a device for producing mouldings from foamable plastic particles, with a two-part or multi-part mould in which steam chambers are formed on the reverse side of the mould walls, the condensate outlets (17, 27) of the steam chambers (13, 23) are connected, via a steam condenser (43) with a water spray device (45) mounted therein, to a vacuum pump (40) to make the extraction of steam from the steam chambers (13, 23) more effective. A substantial improvement and further development consists in connecting the spray devices (19, 29) contained in the steam chambers (13, 23) for the introduction of cooling medium via a valve (48) to the pressure connector (42) of the vacuum pump (40), by which means a mixture of gas, water and any residual wet steam is fed to these spray devices (19, 29). This mixture can be substantially better metered and distributed to the rear surfaces of the mould walls (12, 22). The suction action of the vacuum pump can be used in the device for further functional improvements (improved extraction of the filling air); the super-atmospheric pressure acting at the pressure connector (42) of the vacuum pump (40) can also be used for functional improvements of the device (release of the moulding from one or other mould wall, support during ejection). <IMAGE>
Patent DE-3120313-A1 (DE)
Title: Reading aid for loose-leaf publications
Inventor: WOLSKI GEB EY
IPC: A47B23/04
Filed: 1981-05-21
Abstract: The invention relates to a mechanically functioning book support for loose-leaf publications. The purpose of the invention is to allow a loose-leaf publication to be read at any opened out position, whether at the front, in the centre or at the back, at an angle as if the loose-leaf publication were opened out precisely in the centre. The underlying object of the invention is to avoid continuously necessary head movement and poor body posture when reading a loose-leaf publication. This object is achieved in that the book back holding plate (3) is automatically counterbalanced about its longitudinal axis by means of springs (6 and 7), depending on the imbalance of the number of sheets corresponding to the page at which it is open. Additionally, the angle of inclination between the book back holding plate (3) and the baseplate (11) can be varied. The back of the loose-leaf publication is fastened to the book back holding plate (3) by retaining angles so that the loose-leaf publication does not slip when pages are turned. Two extending arms (20 and 21) give the reading aid a firm standing base. <IMAGE>

Title: Loading bridge for ramps
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1981-08-04
Abstract: These bridges have a platform which is mounted pivotably on a truck which can be driven on a fixed rail transversely to the longitudinal direction of the bridge. In order to be able to carry out assembly of the truck and thus of the loading bridge at any desired point on the rail, the rail is provided at the upper edge with a bend which is directed downwards and against whose inner surface a wheel of the truck rests. Provided at the lower edge of the rail at the free end of a horizontal bend is a downwardly directed curve in order to maintain the resistance of the rail to bending and to allow introduction of the parts of the truck from the front into the interior of the profile. Furthermore, an assembly bar is provided, to which the parts of the truck (wheels) can be attached and which is fitted with screw bolts in order to be able to produce a connection of said assembly bar with the remaining parts of the bridge by nuts which can be screwed on from the outside.
Patent DE-3132825-A1 (DE)
Title: Gas-blast circuit breaker
Inventor: AESCHBACH BRUNO
IPC: H01H33/90
Filed: 1981-08-19
Abstract: A stationary contact element (11) and a moving contact element (20) are arranged in a surrounding space (33) which contains an extinguishing gas. Said moving contact element (20) is provided with an axial passage (22) which originates from its free end (21) and leads over a limited length, and is surrounded by a blowing nozzle (14) which, in the switched-on position, is closed by the stationary contact element (11). The inlet (17) of the same communicates with a pump space (19) which is subjected to pressure during a switching-off stroke and is bounded by a pump piston (24) and a pump cylinder (16). Openings (23) originate radially from that end of the axial passage (22) which faces away from the free end (21) of the moving contact element (20). These openings (23) pass through the moving contact element (20), are closed in the switched-on position and produce a connection between the axial passage (22) and a suction space (34) during a switching-off stroke. This suction space (34) is bounded by a suction cylinder (26) and a suction piston (29) which moves with the moving contact element (20). The suction space (34) is connected to the surrounding space (33) via pressure-relief valves (32) which open in the direction of said surrounding space (33). The connection between the suction space (34) and the surrounding or blowing-out space (33) is thus not produced as a function of the distance travelled during the switching-off stroke but as a function of the pressure prevailing in the suction space (34). In consequence, effective blowing out (blasting) of the switching arc (35) is considerably improved while switching off both high currents and low currents. <IMAGE>

Title: Process for the preparation of cycloheptanone
Inventor: STOBER REINHARD DIPL CHEM DR
IPC: C07C45/58
Filed: 1981-09-17
Abstract: Cycloheptanone is obtained by rearrangement of cycloheptene oxide in dimethyl sulphoxide or dimethylformamide in the presence of sodium iodide; the sodium iodide can be recovered again in a simple manner from the rearrangement of the mixture after removal of the bulk of cycloheptanone and immediately fed back into the rearrangement step as a catalyst.
Patent DE-3138659-A1 (DE)
Title: Test method for detecting defects in welds
Inventor: KOCH FRIEDRICH-OTTO DIPL ING
IPC: G01N29/11
Filed: 1981-09-29
Abstract: To evaluate ultrasonic signals from weld defects, use has hitherto only been made of their maximum amplitude compared with a test defect threshold level. An improved test method is proposed in which the weld defects are assessed for their actual harmful effect, ie their length and area, by the ultrasonic pulse echo test method. Ultrasonic defect signals received are digitised and computationally combined with signals from a length measuring device for the associated section of the workpiece to produce a raster-type defect display surface. These surfaces can be computationally compared in terms of their classification with defect area catalogues and defective workpieces can be removed.
Patent DE-3144924-A1 (DE)
Title: Tamper-proof closure for bottle-type containers
Inventor: HEINLEIN HANS
IPC: B65D55/08
Filed: 1981-11-12
Abstract: A tamper-proof closure for bottle-type containers (10) is proposed in the form of a screw cap (1) with an internal thread (2) which interacts with an external thread (11) on the bottle-type container (10). To indicate initial opening of the container (10), no tear-off parts are provided, but the corresponding indication takes place by an irreversible change in shape of the indicating means of the closure state. According to the invention, a tamper-proof element (6) is moulded integrally onto the lower edge of the screw cap (1), initially projects downwards over the lower edge (13) of the screw cap (1) and is subsequently folded back by means of a tool into the interior of the screw cap (1) in such a way that its inside diameter is smaller than the outside diameter of the threaded ribs of the external thread (11) on the bottle-type container (10) or is smaller than the outside diameter of a transfer ring (15) on the neck (16) of the bottle-type container (10). It is thus achieved that, when the screw cap (1) is unscrewed (opened) from the corresponding container (10), the tamper-proof element (6), either in the form of a ring (7) or in the form of edge tabs (8), is in turn pulled downwards out of the screw cap (1) and thus indicates that the closure has been opened. <IMAGE>
Patent DE-3148412-A1 (DE)
Title: Double-band press
Inventor: STAEBLER GERHARD
IPC: B30B5/06
Filed: 1981-12-07
Abstract: The invention describes a double-band press having two rotating steel bands which are guided via driving drums and which receive between two band portions pointing towards one another the material which is to be pressed, the transmission of the pressure force being carried out by means of pressure plates, and stripping means for the friction-reducing transmission of the pressure forces from the pressure plates to the material to be pressed being provided between the pressure plates and the respective steel bands. According to the invention, a protective band is provided respectively between a steel band and the stripping means. This protective band affords the possibility of sufficiently lubricating the stripping means, whether they be roller-type stripping systems, sliding stripping systems, air-cushion stripping systems or oil-stripping systems, so that the wear of the stripping means can thereby be reduced considerably. The protective bands prevent the possibility that the lubricant will pass onto the steel band, and therefore their drive is guaranteed reliably because the steel bands no longer slip through on the driving drums, as was the case in the known types.
Patent DE-3148870-A1 (DE)
Title: Method for changing the temperature gradient in a room and room ventilation device for implementing the method
Inventor: PFEIL WERNER
IPC: F24F7/06
Filed: 1981-12-10
Abstract: In a process for changing the temperature gradient in a room, the air is drawn in in a horizontal air layer of the room in a limited region. The air drawn in is then blown out in another region of the room. A room ventilation device for implementing the method contains a housing with at least one air inlet and one air outlet, a blower being arranged in the housing. The air inlet is situated in this case in the air layer of the room, from which the air is drawn in, while the air outlet is arranged in the air layer, in which the drawn-in room air is blown out.
Patent DE-3151238-A1 (DE)
Inventor: FEITEN ERWIN DR ING
IPC: D06J1/06
Filed: 1981-12-22
Abstract: In an apparatus for guiding the folding blades (3,5) and for actuating the tilting arm (24) of a blade bar (4) mounted pivotably on the jib (10) of a blade shaft (11), a reversible individual drive (23) with a pivoting member (21) which can move a rocker (16) to and fro between two positions serves for actuating the tilting arm (24). Mounted pivotably on the rocker (16) is an intermediate member (14) on which the tilting arm (24) is articulated on a pivot pin (13) at a distance from the point of articulation of the intermediate member (14) on the rocker (16). The geometry of the articulated chain formed by the jib (10), the pivoting member (21), the rocker (16), the intermediate member (14) and the tilting arm (24) is, at the same time, selected so that the tip of the particular folding blade (3) is guided along on the upper or lower contact plate (7,8 ) of the pleating machine as a function of the position of the pivoting member (21).
Patent DE-3202333-A1 (DE)
Title: Cover cap for locks
Inventor: FROMMANN MANFRED
IPC: E05B17/18
Filed: 1982-01-26
Abstract: The invention relates to a cover cap for locks, especially for locks and door handles of vehicles. A cover cap (1, 11) preferably consists of an elastic material which bears sealingly with its inner face (3) against a lock to be covered. For this purpose, the inner face (3) of the cover cap is matched to the external shape of the particular lock to be covered. To obtain an especially good sealing, elevations (4, 5, 6, 7) are formed on the inner face and engage into corresponding recesses of a lock. At the same time, there can also be a stud (7) which engages into the slit-shaped keyhole of a cylinder lock and which, if appropriate, catches there. The cover cap according to the invention prevents, in particular, the penetration of moisture and therefore the freezing up of locks at relatively low temperatures. <IMAGE>

Patent DE-3209753-A1 (DE)
Title: Remotely controlled information device
Inventor: SANDER HEINRICH DIPL ING
IPC: G09F9/00
Filed: 1982-03-17
Abstract: The information device serves to provide passenger information in public transport systems. It consists essentially of a flat display module (AB) for accommodating a multiplicity of luminous elements (L) and an information carrier (J) mounted thereon. This information carrier serves the diagrammatic representation of routes. It is possible for entirely specific stopping points (A to H) to be marked on it optically by selective switching of luminous elements. The marked stopping points assist the passengers to determine position; they are intended to enable the passengers to prepare themselves to dismount in good time. The information carrier (J) or the display module (AB) as a whole are exchangeable, so that if required it is also possible for other routes to be travelled. A remote control device is provided for switching the luminous elements, and can be switched on automatically or by hand; an infrared remote control has proved to be particularly advantageous. <IMAGE>

Title: Method of measuring the ion concentration of a sample
Inventor: YOSHINARI SHIGERU
IPC: G01N27/416
Filed: 1982-05-28
Abstract: The ion concentration of a sample is measured by introducing the sample into a measuring vessel containing three ion-selective electrodes (32a to 32c) and a reference electrode (33), measuring an electrode potential, introducing a standard solution of known ion concentration into the measuring vessel after removing the sample from it, measuring an electrode potential and taking the difference between these two electrode potentials. After a comparatively long interruption of the measurement, during which the electrodes remain immersed in the standard solution, the state of the electrodes is established by introducing the standard solution repeatedly, namely four times, into the measuring vessel and removing it from the latter, measuring four electrode potentials during these repeated steps while the electrodes are immersed in the standard solution, taking the difference between the third and fourth electrode potential, and then comparing it with a predetermined permissible differential value in order to assess the electrodes as altered and deviating from the standard if the difference is greater than the permissible differential value. <IMAGE>
Patent DE-3224025-A1 (DE)
Title: Converter for converting digital into analog signals by means of charge coupled devices (CCD)
Inventor: GRUETER OTTO DR RER NAT
IPC: H03M1/00
Filed: 1982-06-28
Abstract: The invention relates to a digital/analog converter which operates in such a manner that a charge quantity, which is kept ready under an electrode, is divided by means of a charge divider and is now separately temporarily stored under two other electrodes. One of the two part charges is then kept ready in a further electrode and, at the same time, the other charge is shifted by means of shifting electrodes, controlled only by the relevant bit value, into one of two possible electrodes where it becomes mixed with further charges which may be present there. These charges, too, are subsequently shifted in such a manner that a further part-charge smaller by a factor of (2) can be mixed with them again information-dependently controllably in the next time step in a next similar stage. This method is continued according to the number of bits per bit pattern until an information charge corresponding to the original bit pattern has been created in the respective output electrode. In addition, each electrode contacted by information-determined charges contains at least one basic charge at any time. <IMAGE>

Patent DE-3226639-A1 (DE)
Title: Magnetic recording medium
Inventor: YANAI AKIO
IPC: G11B5/85
Filed: 1982-07-16
Abstract: A magnetic recording medium is described which has a base material, according to a preferred embodiment with a surface roughness of 0.012 mu m or less, and at least two thin magnetic films which are vaporised onto the base material. The films are formed in an atmosphere of an oxidising gas by continuously changing the angle of incidence of a stream of vapour of a magnetic material on the moving base from a high value to a low value. By this means, the film acquires a curved and slanting column structure. The resulting magnetic recording media have improved weather resistance, a longer life and excellent electromagnetic properties.
Patent DE-3232182-A1 (DE)
Title: Disengaging safety clutch with automatic re-engagement
IPC: F16D43/206
Filed: 1982-08-30
Abstract: The present invention relates to a disengaging safety clutch with automatic re-engagement, in which two clutch halves (12, 13) are arranged on a hub (11) and one clutch half is connected in torsionally rigid fashion to the hub (11) and spring-loaded towards the other clutch half (13), which is rotatable relative to the hub, the parting plane between the clutch halves having a plurality of balls (14) which are arranged on a circle and are guided by a ball cage (4). In the engaged condition, the balls are, for the purpose of transmitting torque from one clutch half to the other, seated in spherical recesses (21) in the mutually facing front faces of the two clutch halves and, when a torque overload occurs, move out of the spherical recesses, one clutch half being displaced axially counter to the spring loading (15), and assume a disengaged position between the clutch halves, in which they do not transmit any torque. The novelty of the first solution principle is regarded as the fact that, upon disengagement, the balls (14) fall into very much larger spherical recesses, from which they are guided back into the starting position with the aid of the ball cage (4) by a procedure in which the clutch halves which have moved apart are rotated slowly relative to one another and an engagement pin (5) takes along the ball cage (4) as they do so. The novelty of the second solution principle consists in the fact that a locking pin (56) falls into the axially displaceable clutch half (12') at its maximum axial displacement and the balls (14'), held captive in the ball cage (4') are guided back into the starting position on the other clutch half due to a resilient preloading of the cage.
