Patent DE-3510986-A1 (DE)
Title: Keyboard for keyed musical instruments, having keyboard keys of a manual which are distinguished by colour, shape or other features
Inventor: MARHOLD GERHARD
IPC: G10C3/12
Filed: 1985-03-22
Abstract: The object of the invention is to achieve a substantial simplification of the learning of keyboard instrument playing technique. Conventional keyboards of musical instruments (such as pianos and organs) are based, as regards the arrangement of the keyboard keys, on a particular musical key (C major). Other musical keys are played by making different use of the accidental (black) keyboard keys. Thus each musical key requires the use of a separate combination of black and white keyboard keys - 12 different combinations are assigned to the 12 major musical keys alone. This variety makes it considerably more difficult to learn to play the piano or organ. In accordance with theory, all musical keys of the same mode are equivalent. This situation is reflected by keyboards with a chromatic configuration. In these, the problem arises of assigning the keyboard keys to particular musical keys and of orientation on the keyboard. According to the present invention, these problems are solved by a chromatic keyboard arrangement together with a variable and/or permanent keyboard identification. The preferably electronic adjustable keyboard identifications permit the marking of the keyboard keys belonging to any desired musical key. In addition, orientation on the keyboard is assisted by a proposed colouring of particular keyboard keys, preferably such that a suitable linear system of notation is imaged directly on the keyboard.

Title: Clearing device for a slotted wall cutter
Inventor: BAUER KARLHEINZ DR ING
IPC: E02F3/20
Filed: 1985-04-22
Abstract: In a clearing device for extracting cut material from a cutting wheel of a slotted wall cutter for earthworking, it is envisaged that the clearing arm can be moved to and fro in the axial direction of the cutting wheel and that the clearing arm is guided forcibly through between cutting teeth following one another in the circumferential direction of the cutting wheel. In this manner, both the cut material situated on the cutting wheel circumferential surface after the cutting out of the ground and the material adhering between the cutting teeth is virtually completely cleared out.
Patent DE-3519358-A1 (DE)
Inventor: DITSCHEID HANS-LEO
IPC: B29C48/05
Filed: 1985-05-30
Abstract: The cable consists of a core containing at least one optical fibre (LWL) and at least one strain relieving element, and of a sheath which slidably envelopes the core and on which after extrusion and cooling an axial force is exerted by a device acting on its outer surface, the sheathed optical cable thereafter being reeled up. In order to achieve the object of completely preventing the cable core from suffering the harmful effects of contractions in the case of the use of an arbitrary material, it is proposed that the device (11) exerting an axial force exerts a thrust in the direction towards a downstream conveyor (7), and that the conveying speed thereof is greater than the speed with which the cable is pulled into the downstream conveyor (7) by which the core (8) and the sheath (4) are conveyed synchronously with respect to one another. <IMAGE>

Title: Method and device for automatically recording incoming telephone calls
Inventor: WEBER REINHARD
IPC: H04M1/656
Filed: 1985-06-14
Abstract: In a method and device for automatically recording incoming telephone calls by means of a recording device connected to the telephone system, all incoming telephone calls are recorded continuously in permanent operation on a recording medium 8 which has a predetermined limited storage capacity and which is provided in the recording device 1, and these telephone calls, in each case based on an incoming call, are erased continually by corresponding subsequent telephone calls once the storage capacity of the recording medium 8 has been taken up, with simultaneous recording of the subsequent telephone calls. When a call containing an alarm, in particular a threat or warning etc., is received, the recording device 1 is disabled at the end of this threatening call so that the call recording of the last recording interval which contains this threatening call is available on the recording medium 8 of the recording device 1 for the purposes of criminal analysis or the like.   <IMAGE>
Patent DE-3532389-A1 (DE)
Title: Cutting tool for a coal plough and the like
Inventor: KROHM REINOLD
IPC: E21C35/18
Filed: 1985-09-11
Abstract: In a cutting tool, in particular for a coal plough and the like, which consists of a pick box and a pick, the plate-like shank of which can be inserted into a slot in the pick box, the outer lobes forming the slot of the pick box are connected only to the goaf side and to the rear side of the tool by transverse webs so that, compared with the pick arrangements belonging to the prior art, the pick, while retaining a simple frontal insertion capacity and clamping capacity by means of clamping elements lying in a protected position, can also project up to its shank base and in addition by a certain impact depth relative to the pick box, as a result of which not only is total frontal protection of the pick box made possible but a breaker comb arranged downstream of the cutting front is formed, in particular in the case of raised ploughs, which breaker comb prevents the coal-face rib formation impairing the actual cut by blocking the front tips of the picks and rips projecting rock packs. Due to the compact, protected construction unit, possible uses also present themselves in mineral-extracting mining machines other than the coal plough representing them.

Patent DE-3532541-A1 (DE)
Title: Roving-blocking device on drawing units of spinning machines
Inventor: SEEBO KURT
IPC: D01H13/18
Filed: 1985-09-12
Abstract: A roving-blocking device has a blocking wedge which clamps the roving between itself and the lifted-off upper roller. To adapt to a variation in the width of the drawing zone, this blocking wedge, which is fastened to a slide screwed to a supporting rail, must be displaced. To avoid having to release the screw connection for this purpose, compression springs are looped around the screw shanks, so that the upper part and lower part of the slide are held braced against one another by spring force. As a result of pressure on the screw heads via an adjusting piece, the bracing is released and the lower part comes with its countertoothing out of engagement with a rack which is arranged in the supporting rail and which serves for actuating the blocking wedge. In this position, the slide can easily move on its supporting rail into the desired position. After the removal of the adjusting piece, the countertoothing engages into the rack again, and the compression springs once more brace the lower part and upper part with one another.

Filed: 1985-10-28
Abstract: Bis(aminonitrophenyl)methane can be obtained in one step in approximately quantitative yield when o-nitraniline and formaldehyde are subjected to a condensation reaction in water at a temperature between 20 and 40 DEG C in the presence of sulphuric acid and the resulting methylenebis(o-nitraniline) undergoes a rearrangement reaction by treating the reaction mixture at a temperature between 90 and 100 DEG C.
Patent DE-3540927-A1 (DE)
Title: Two-limb core laminate having latching of two laminate parts
Inventor: WAASNER BRUNO
IPC: H01F27/245
Filed: 1985-11-19
Abstract: A two-limb core laminate exists, consisting of two laminate parts (1, 2) which are of unequal size and jointly surround a rectangular core window (3), the smaller laminate part (2) having a recess (7) which (when the laminate parts are pushed together) latches into a tab (9) on one limb (6) of the larger laminate part (1), and the smaller laminate part (2) is stamped out of the larger laminate part (1). In this case, it is desirable if (while maintaining the avoidance of the laminate parts engaging in one another), in the case of the window corners, the tab of the one latch interacts with the associated recess with increased accuracy. This is achieved in that the smaller laminate part (2) is twisted through 180 DEG  with respect to the larger (1) after stamping, and the larger laminate part (1) has on that limb (6) which is opposite the recess (7) a cut-out (10) which corresponds to the tab (9), the joint (5) between the two laminate parts (1, 2) overall running in the limbs (6). The cut-out which is caused by the production of the tab does not cause interference since it is at a distance from the window corner, that is to say is arranged in the limb in a region where the density of the lines of force is low. <IMAGE>

Title: Sealing roll
Inventor: BODACH SIEGMUND DIPL ING
IPC: B29C65/18
Filed: 1985-12-16
Abstract: The invention relates to a sealing roll with temperature sampling for bonding plastic film webs in which the temperature is sampled by means of a temperature sensor inserted in a contact body and is fed to a temperature control device. The aim of the invention is to keep measurement fluctuations in the course of sampling on longitudinal sealing rolls as small as possible. The object is to determine the temperature via a low-friction contact sampling and to feed this to a control device. According to the invention the object is achieved in that the reverse side of the sealing roll is covered with a disc of readily heat-conducting material and in that the contact body, equipped with the temperature measurement sensor, is arranged in the rotational centre of the disc. The contact body consists of a carbon brush and is pressed by spring force against the disc. The reverse side of the sealing roll is machined with an annular clearance and the disc covers the entire diameter of the sealing roll. <IMAGE>
Patent DE-3614130-A1 (DE)
Title: Fluid level sensor
Inventor: LANG MANFRED DR ING
IPC: G01F23/292
Filed: 1986-04-25
Abstract: A fluid level sensor for monitoring a minimum level consists of a transmission light waveguide (1) which ends at the level of the liquid level to be monitored and a reception light waveguide (3) which begins there and between whose endfaces (5, 6) which extend preferably obliquely to the respective longitudinal axes there is a gap (a) which is accessible for the fluid (7). In this way, it is ensured that the optoelectric transducer (4) which is coupled to the reception light waveguide (3) supplies a signal whenever the fluid level is above the minimum level. This reversal of the previously customary principle of signal emission prevents a defect in the monitoring circuit being incorrectly interpreted as a satisfactory level. <IMAGE>

Inventor: MILLER WALTER DR
IPC: G01D11/24
Filed: 1986-07-11
Abstract: An enclosed measuring device for measuring the relative position of two objects which are movable relative to each other includes a housing provided with a longitudinal slot. The slot is closed by means of cover members mounted in a chamber of the housing. The cover members are comb-shaped in transverse cross-section and are arranged so as to mesh with each other, resulting in a labyrinth-type line of contact between the cover members. A carrying member providing the connection between the interior of the housing and one of the objects has a meander-like shape conforming to the labyrinth-type line of contact between the two cover members, so that an effective sealing action is ensured even at the location where the carrying member extends through the cover members.

Title: Reloadable ink-ribbon cartridge for typewriters or office machines of similar design
Inventor: BEHRENS ROLF ING GRAD
IPC: B41J32/00
Filed: 1986-07-15
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar design are subject to different construction requirements, the intention being, above all, for them to be easily exchangeable by means of one-handed operation. Since the ink-ribbon cartridges are moreover designed as disposable items, many still functional individual parts are also thrown away. In order to avoid this, ink-ribbon cartridges with exchangeable ink-ribbon spools are known. The invention is based on the object of providing a reloadable ink-ribbon cartridge in which the exchange of the ink-ribbon spools (4, 5) is possible with few manipulations. In this case, the engagement and disengagement of the spring-mounted receiving spool (5) with the pin wheel (9) of the feed roller (10) is to be easy to handle. For this purpose, a manual adjustment lever (75) is provided, which is mounted with a bearing journal (78) in a bearing bore (79) on the side wall (77) of the bottom part (6) so as to be pivotable into free positions, and it is provided that the manual adjustment lever (75) at the upper end of the bearing journal (78)... a locking arm (80) which protrudes out of the cartridge housing and by means of which the lid (2) can be locked on the bottom part (6) in one end position of the manual adjustment lever (75), and at the lower end of the bearing journal (78) a stop arm (81) which can be pivoted over the bottom and by means of which the pivoting lever (57)... for raising the receiving spool (5) from the pin wheel (9) of the feed roller (10) during the movement of the manual adjustment lever (75) into the...

Filed: 1986-08-25
Abstract: Sterically hindered cyclic amines, the basic nitrogen atom of which is substituted by a photoactivatable acyl group, can be deacylated by UV irradiation. This is advantageous if the basicity of the amines interferes in the application. Examples of such photoactivatable acyl groups are phenylglyoxyl, phenylacetyl or naphthylacetyl groups. The compounds are utilisable as light-stabilising agents for polymers, in particular for acid-curable resins.
Patent DE-3630091-A1 (DE)
Title: Fuel injection system
Inventor: SETTER SIEGFRIED DIPL ING
IPC: F02M69/38
Filed: 1986-09-04
Abstract: A fuel injection system is proposed, which serves for the fuel feed of an internal combustion engine. The fuel injection system comprises a fuel pump (5), which delivers fuel into a fuel feed line (3), in which fuel metering valves (1) are situated, on which a constant pressure difference can be controlled by control valves (13), which pressure difference is influenced by a pressure control valve (20). The pressure in the fuel feed line (3) can be controlled by a system pressure control valve (9), in the connection (26) of which to the fuel feed line (3) a restrictor (43) is arranged, which can be operated by a solenoid (44), which can be triggered by an electronic control unit (32) as a function of operating variables of the internal combustion engine. A displacement of the restrictor (43) into its throttling position causes an increase of the fuel pressure in the fuel feed line (3) and hence an amplification of the control pressure drop on the pressure control valve (20), in order, for example, to ensure reliable starting of the internal combustion engine below certain temperatures. <IMAGE>

Filed: 1986-10-01
Abstract: In an optical device for projecting liquid crystal displays, in particular for overhead projectors having a liquid crystal plate (12) in the projection plane and a Fresnel lens (13), the projected light rays (23) irradiating from a projection lamp propagate in parallel or essentially parallel directions within the liquid crystal plate (12). In an overhead projector working on the basis of the principle of reflection, a Fresnel lens (13) is arranged above the side of the liquid crystal plate (12) facing the projection lamp (18) and a plane mirror (14) is arranged below the side of the liquid crystal plate (12) facing away from the projection lamp (18). With this arrangement an incident light ray (23) coming from the projection lamp (18) can re-emerge through the same open cell (20) of the liquid crystal plate as that through which it came, after being reflected by the plane mirror (14). This simple arrangement prevents the formation of shadows and ghost lines during the projection of liquid crystal displays.

Title: Method for the winding of threads
Inventor: GERHARTZ SIEGMAR DIPL ING
IPC: B65H59/38
Filed: 1986-10-24
Abstract: In the winding of threads, especially chemical threads, to form cylindrical cross-wound bobbins, two different traversing methods can be employed. In random winding, the traversing speed remains constant. In precision winding, the traversing speed is reduced in proportion to the spindle rotational speed. Precision winding can also be carried out in that the variation in traversing speed with the decreasing spindle rotational speed takes place only within specific limits, and in that, when the predetermined lower limit is reached, the traversing speed is switched back to a predetermined upper limit. Both winding methods have advantages and disadvantages. In particular, stepped precision winding prevents mirror-image windings from occurring. On the other hand, it necessitates a very high outlay in electronic and mechanical terms. For this reason, the random-winding method is adopted at the start of the winding run, whilst a change-over to precision winding takes place subsequently. This is based on the knowledge that the occurrence of mirror-image windings can also be prevented at the start of the winding run in the random-winding method by the conventional means.
