Patent DE-3106265-A1 (DE)
Title: Method for storing meat and apparatus for carrying out the method
Inventor: SCHLEGEL JUERGEN
IPC: B65D21/02
Filed: 1981-02-20
Abstract: Containers (1) are constructed roughly boxlike, closed on all sides up to their top side. They serve for storage of, in particular, deboned meat in its own juice. They have edge profiles (7 and 7a) on the top edge (4) and on the bottom edge (8), which gives a secure connection when they are stacked one on top of the other. The container situated above a container (1) simultaneously forms in each case by its bottom (9) the closure of the container situated beneath. For the container (1) standing at the top, either a lid (5) if necessary with an additional weight (6), or else a water bag (15) can be provided. The storage of meat (2) in its own juice with substantial exclusion of air has the advantage that comparatively long storage without chemical or other additions is possible, the meat, after its removal from the container (1), having good quality and fresh appearance. <IMAGE>

It is held in a desired position by at least three clamping screws (4) arranged on the basin in one plane. <IMAGE>
Patent DE-3111232-A1 (DE)
Title: Abrasive papers or cloths
Inventor: BITZER DIETHELM DIPL CHEM DR R
IPC: B24D3/34
Filed: 1981-03-21
Abstract: The invention relates to abrasive material on a flexible underlay, such as for example abrasive papers or cloths, which are produced by known processes but the top binder coating of which contains microglass beads of 1-500  mu  (microns), preferably 1-150  mu , the abrasive grains bonded on the flexible substrate by the base binder being additionally secured in the top binder by the microglass beads. In particular, the abrasive grains are protected by the microglass beads contained in the top binder from smearing with abrasive dust until the microglass beads in the top binder break out during the abrading operation. This is facilitated under the loading applied during abrasion by the abrasive grains not being completely shielded by microglass beads. Instead, the tips of the abrasive grains are freed already during initial abrading and lower-lying grain tips of the abrasive material are successively freed only later during abrading.
Patent DE-3112846-A1 (DE)
Title: Method for transmitting binary pulse duration modulated signals in telephone switching systems, in particular small telephone PABX systems
Inventor: BLOSSFELDT DIETER DIPL ING
IPC: H04L25/49
Filed: 1981-03-31
Abstract: To transmit information for visual and/or audible display elements (A) disposed on the individual terminals (T1-Tn), pulse duration modulated signals which also differ in terms of their pulse amplitude are transmitted as binary values from a central device (ZE) in small telephone PABX systems. The transmission levels are selected in such a way that the respective product of pulse width and pulse amplitude has approximately the same value for both pulse types (F0, F1). Regardless of the type of the successively transmitted signals, the same voltage level thereby occurs for each signal on the coupling-out elements at the receiving end. The separation between the initial potential of the rising pulse edge and the open-circuit potential from pulse to pulse is thereby prevented from increasing in the case of a sequence of voltage pulses assigned, for example, to the binary value (1), which would be the case without the use of different amplitude values. No disadvantageous level shift can therefore occur, provided that a fixed evaluation threshold has been specified. <IMAGE>

Patent DE-3115599-A1 (DE)
Inventor: GAERTNER FRANZ GEORG DR RER NA
IPC: F25D21/00
Filed: 1981-04-16
Abstract: 1. A method of operating a refrigerator in which in each case, the duration of a specific useful operation of the refrigerator which results in the frosting-up of its evaporator, is determined by the time of a defrosting process which precedes the useful operation in question and a defrosting process which follows the useful operation, characterised by the combination of the following features : 1.1 the refrigerator is operated as a heat pump ; 1.2 a defrosting process is initiated only when the instantaneous value of one of the state variables of the refrigerating agent in the evaporator, either the pressure or the temperature, falls below a lower limiting value ; 1.3 when the lower limiting value of the state variable is reached, the useful operation is interrupted, a defrosting process is initiated, and a first timing procedure (t) is commenced ; 1.4 as soon as the state variable has risen to an upper value during the defrosting process, the defrosting process is terminated, the refrigerator is switched to useful operation, and the first timekeeping procedure is terminated and the result thereof is stored ; 1.5 the useful operation is continued if, after a stipulated basic time (tG ), the state variable still lies below the lower limiting value ; 1.6 the useful operation is interrupted again and a defrosting process is initiated if, after the expiry of the basic time (tG ), the instantaneous value of the state variable is equal to or less than the lower limiting value, and at the beginning of the defrosting process which follows the useful operation, a second timing procedure (t) is commenced ; 1.7 on the termination of the last defrosting process to have been executed (which termination takes place when the upper limiting value of the state variable is reached), the second timing procedure (t) is likewise terminated and the result of this timing procedure is stored ; and 1.8 all the succeeding useful operation times are in each case determined by the basic time (tG ) and a correcting value (Kw ) which is added to this basic time and which is formed from the stored last-but-one timing value minus the stored last timing value and from a constant (k) which serves as amplification factor.

Title: Control circuit for liquid-fuel combustion arrangement
Inventor: YOSHII HISAO
IPC: F23N1/00
Filed: 1981-04-28
Abstract: The invention relates to a control circuit for a liquid-fuel combustion arrangement, which uses a difference amplifier (3) and a square-wave generator (9) to maintain strong, constant combustion in the burner (31) until the difference amplifier (3) registers that the room temperature has approached a preselected target temperature; at this point in time the difference amplifier (3) acts on the square-wave generator (9) to alter its output signal such that the extent of combustion is reduced in inverse proportion to the room temperature when the target temperature is reached. The difference amplifier (3) subsequently controls the square-wave generator (9) such that fuel is available to an extent necessary and sufficient for maintaining the target temperature. <IMAGE>

Title: Handle with clamp device for tubular sheath
Inventor: HOLLAND-LETZ HORST DIPL ING
IPC: B25G3/20
Filed: 1981-06-03
Abstract: The invention relates to the connection between a tubular sheath and an inserted handle, preferably made of plastic. Known connections of a similar type have threads, or an O-ring on the inserted handle serves as a static friction element. These connections are relatively expensive, and the threaded connection can come loose during working. The object is to provide a cost-effective, but functionally reliable connection. This object is achieved by virtue of the fact that the handle body made of elastic material has two short, axis-parallel slots, by means of which two bridge-shaped webs are formed in the handle body. The webs have raised parts on their outer surfaces, the backs of these raised parts projecting beyond the external diameter of the handle. When the handle is inserted into the tubular sheath, the bridge-shaped webs are pressed together radially via the raised parts and act as clamping elements. Clamping devices of similar shape can be fitted where a non-positive connection is sufficient. In the drawing, the figures show the handle (1) with the bridge-shaped clamping elements (2), the raised parts (3) sitting thereon, the axis-parallel slots (4) and the tubular sheath (6). <IMAGE>

Title: Electrical capacitor
Inventor: FINK RUDOLF DIPL ING
IPC: H01G4/28
Filed: 1981-06-05
Abstract: An electrical capacitor which consists of ceramic, tubular dielectric bodies (1, 2) on which metal layers (5, 6, 7, 8) of the foils are arranged in a fully adhering manner, and in the case of which the connections (14, 15, 31, 41) of the capacitor are electrically conductively mounted on the metal layers (5, 6, 7, 8) of the foils. In this case, two tubular dielectric bodies (1, 2) are arranged axially at a distance one behind the other. In each case one metallic connecting element (3, 4) extends through a central hole (13) in a tubular dielectric body (1, 2) as far as the outer jacket surface of the axially adjacent tubular dielectric body (2, 1) and is electrically conductively connected to the metal layer (6, 8) of the foil of the central hole of one tubular dielectric body (1, 2) and to the metal layer (5, 7) of the foil of the outer jacket surface of the axially adjacent tubular dielectric body (1, 2). <IMAGE>

Title: Apparatus for the manufacture of slats for a blind
Inventor: EDIXHOVEN GERARDUS HENDRICUS P
IPC: B60P1/46
Filed: 1981-06-10
Abstract: The invention relates to an apparatus for the manufacture of slats for a blind, the apparatus having, inter alia, an ejector for the finished slats. At high production rates, there is a high risk that slats, especially those which are relatively narrow and/or relatively thin will be damaged when ejected by an ejector. Other disadvantages of the known ejectors are the technical outlay and space which have hitherto been required. To avoid these disadvantages, the invention proposes that the ejector has a pivoted arm arranged in the vicinity of the drive shaft, this pivoted arm being pivotable about an axis parallel to the drive shaft and the slat undergoing processing being located in its pivoting range, and that an actuating element mounted on the drive shaft and rotating with the latter pivots the pivoted arm in such a way in the ejecting direction after production of the slat that the increase in speed is limited to a predetermined value, at least in the first part of the ejecting movement.
Patent DE-3127231-A1 (DE)
Title: Device for electric stimulating current treatment (therapy) in cosmetic institutes and/or medical practices
Inventor: LUGHOFER FREIMUND DIPL ING
IPC: A61N1/32
Filed: 1981-07-10
Abstract: In the case of the device, the electric part, which is provided with a direct current source and to whose output terminals it is possible to apply direct voltage which can be varied in its intensity, is equipped with a changeover switch for reversing the polarity of the treatment current, and the operability of the changeover switch is blocked given a potential of the adjustable direct voltage (UP) which is above a prescribed limit value. In this case, switching contacts which are used to reverse the polarity of the output terminals can be operated by means of a relay, and the latter can be driven by a flip flop in such a way that the relay switches over from one position into the other every time the flip flop flips.

Title: Device for operating a brake light (stop light) on bicycles
Inventor: AVERDUNG CHRISTOPH
IPC: B62J6/04
Filed: 1981-07-24
Abstract: The invention relates to a device for operating a brake light which is actuated by a bicycle cable brake. The invention is used in the sphere of electric circuits on bicycles. In this connection, the construction of a device for operating brake lights on bicycles is proposed which, at the same time, raises the problem of equipping the invention with a maximum degree of operational reliability and, at the same time, of leaving the way open for possibly retrofitting the device. According to the invention, the solution to the problem is achieved by virtue of the fact that a contact shoe (1) is bent around a previously insulated point on the brake cable (10). A contact spring (2) is attached to a holding clip (3) in a manner insulated therefrom such that the said spring does not touch the contact shoe (1) in the rest position of the brake (11). Contact shoe (1) and contact spring (2) are in each case provided with insulated copper wire (7). When the brake (11) is actuated, the current lead (7) is closed. All of the parts of this device exhibit a high degree of operational reliability due to galvanising since this protection prevents corrosion in a virtually optimum manner. In addition, the space-saving construction and the technical simplicity of the retrofitting of the device make this device of interest. <IMAGE>

Title: Comb-type panorama device for theatre stages
Inventor: LILIENFEIN THOMAS DIPL ING
IPC: A63J1/02
Filed: 1981-07-31
Abstract: Theatre stages, especially those with a multipurpose character in municipal theatres and similar houses, are used both for theatrical and for musical performances of all types. Theatrical performances generally require a reduced stage opening width of 7-8 metres and possibilities of entering from both sides, even for relatively large groups of players. Choral or orchestral performances, by contrast, are intended, for reasons of space and spatial acoustics, to use the whole width of the hall as far as possible, with no lateral restriction, and need a minimum width of about 12 metres. The width of the inner frame is changed by displaceable frame towers (lighting supports) or, if necessary, additionally by the main stage curtain. The lateral limitation of the performing surface is generally formed by centrifugal curtains running in stationary rails, which can be changed only with great difficulty. By contrast, the comb-type panorama device, which can be lowered, permits not only easy interchangeability but also ideal adaptation of the individual curtain scarves, which can be threaded as desired into the tension rods which are angled in the manner of a comb, to the requirements of the particular performance. Figure 1 shows the arrangement of the lateral scarves for musical performances, and Figure 2, in contrast, the arrangement for theatrical performances. <IMAGE>

Each microswitch (6) is operated via switching levers (13), switching cam (11), switching member (13a) and spring switching lever (14) with switching member (15) in dependence on the measurement value pointer (5) and the switching point pointers (18). <IMAGE>
Patent DE-3142030-A1 (DE)
Title: Slide fastener with woven carrier tapes and woven-in fastener members
IPC: A44B19/40
Filed: 1981-10-23
Abstract: The invention relates to a slide fastener with woven carrier tapes and fastener members woven into these, produced during the weaving operation and consisting of plastic monofilament yarns. The fastener members are combined, by means of binding-warp yarns offset relative to the weft insertion, with the carrier tape which is otherwise composed of double wefts of basic weft yarn. The binding-warp yarns span two respective fastener members, specifically passing under the double weft of basic weft yarn arranged between them. They are also tied into the carrier-tape region located under the fastener members. The double wefts of basic weft yarn between the fastener members are drawn through the binding-warp yarns up to or above the level of the upper legs of the fastener members. The binding-warp yarns, after spanning the fastener members, are guided under the double weft of basic weft yarn which is arranged under the next fastener member. They are then guided directly again over two fastener members, passing under the drawn-up double weft of basic weft yarn arranged between them. The binding-warp yarns preferably run in a register of six weft insertions. <IMAGE>

Title: Process for production of glass from a metal alkoxide solution
Inventor: MISHIMA MICHIHARU
IPC: B32B17/00
Filed: 1981-10-26
Abstract: In the production of quartz glass, which may contain additional metals, for example Ti or Zr, from a solution of a silicon alkoxide, if necessary mixed with one or more alkoxides of an additional or additional metals, in water and a hydrophilic organic solvent, in which the solution is brought into a desired form, for example a coating on a substrate, a self-supporting layer, fibres or clumps, if the solution has a suitably high viscosity, and in which the shaped solution is sufficiently heated, a water-soluble organic polymeric substance is added to the solution as an agent for adjusting the viscosity so that the viscosity of the solution soon rises to the desired value. The shaping of the solution can therefore be carried out without having to await continuation of hydrolysis of the alkoxide in the solution, and the glass can be obtained with better uniformity of its properties. The agent for adjusting the viscosity is preferably a cellulose ether, and hydroxypropylcellulose is particularly preferred.

Title: Housing for a proximity switch and process for its production
Inventor: HANESCH WILLI
IPC: H01H9/02
Filed: 1982-02-05
Abstract: Housing for a proximity switch and process for its production, a transparent part, located in the housing wall for optical representation of the switching state of the proximity switch, being fused to the adjacent edge region of the housing in such a way that the two parts form a one-piece unit. The fusing of the transparent zone to the housing wall can be performed by injecting the polymer materials into the mould simultaneously or at different times, the housing material in any case surrounding the material of the transparent part in melted form and forming a molten transitional area between the two with mutual material mixing. Finally, the fusing of the transparent part into the housing wall can also be performed with the aid of an ultrasonic welding process or a laser beam.
