Title: Pneumatic contacting device for the automatic testing of flat modules
Inventor: MUELLER KLAUS-DIETER
IPC: G01R1/067
Filed: 1982-12-30
Abstract: The invention relates to a pneumatic contacting device for the automatic testing of flat modules, by means of which test circuits are electrically tested and the presence of components on the flat modules is checked. The contacting device is formed from a number of pressure pins (DS...) which are carried within a cover plate (AP) and are distributed in such a manner that discrete components of the smallest type can be mechanically and/or electrically sampled. The pressure pins (DS...) are in each case formed from a switching piston (SK) and a working piston (AK) which are supported compressed-air-tight in a common cylinder tube (ZR). All pressure pins (DS...) are controlled via a common pressure chamber (DK) in such a manner that the working pistons (AK) can sample components and test circuits on the flat modules for test purposes via controllable switching pistons (SK). During this process, the pressure pins (DS...) can sample or come into contact with arbitrary surface contours of flat modules to be tested. Such contacting devices are used for automatically testing flat modules, particularly in telecommunications engineering. <IMAGE>

Patent DE-3304100-A1 (DE)
Title: Siliconised textiles
Inventor: SACKMANN MARTIN
IPC: D06M15/643
Filed: 1983-02-08
Abstract: For the permanent impregnation of textiles even during production, silicone elastomers are used. The natural properties and the external appearance are only insubstantially modified by the coating. The fabrics are additionally rendered poorly flammable by the siliconisation. Soiling on the fabrics cannot penetrate into the fibres and is thus easy to wipe off with a damp cloth. The silicone elastomer is applied by means of a roller system to the continuous piece goods directly during the production of the textiles.

Patent DE-3407556-A1 (DE)
Title: Method for soldering wires made of platinum group metals and an apparatus for the production of electrolytically deposited layers of solder on wires made of platinum group metals
Inventor: OTT RUDI DIPL CHEM DR
IPC: B23K1/19
Filed: 1984-03-01
Abstract: A method is proposed for soldering together wires made of platinum group metals with the aid of gold, in which a layer of gold solder is applied to the wire (6) by electro-deposition at the points to be soldered, the points to be soldered are pressed together and the joint is then made by the action of heat. The wire is made the cathode, while the anode bears an electrolyte-impregnated tampon (4) which is brought into contact with the wire (6). The invention furthermore proposes an apparatus for the production of layers of solder on the points to be soldered of wires made of platinum group metals, in which anode discs (3), on the front faces of which there are tampon rings (4), are seated on a rotatable shaft (2). The discs (3) dip partially into the electrolyte (1), with the result that they become impregnated with it. The wire to be provided with the partial layer of gold runs over a guide plate (5) having slots (7) at the locations of the discs (3). When the wire (3) comes to a halt, the shaft (2) is raised such that the tampon ring (4) touches the wire (6). With the electro-deposition current switched on, the wire can thus be plated with gold at these contact points. <IMAGE>

Title: Device for the machine-feeding of elongate brush bodies oriented approximately parallel and lengthwise, and method which can be carried out by said device
Inventor: STEINEBRUNNER WALTER DIPL ING
IPC: B65G47/14
Filed: 1984-04-26
Abstract: A device (1) serves for the metered and approximately positionally correct feeding of brush bodies (2) from a non-arranged supply (4) of brush bodies to a downstream apparatus (25) to which brush bodies have to be fed only in a small quantity and in an approximately parallel position. The device (1) essentially has a metering device (5) which is provided between the receiving container (3) with the supply (4) of brush bodies and the downstream separating apparatus (25). Due to the construction of the metering device (5) with a premetering apparatus (6) and a downstream fine-metering apparatus (7), the brush bodies are removed from the supply container (3) and apportioned in a plurality of conveying steps in relation to their quantity and, during this process, are corrected at the same time at least in their lengthwise position. In this case, an increasing approximation of the position of the brush bodies to the desired parallel delivery position takes place from one conveying step to another. The separating apparatus (25) has, in a vertical arrangement, two supporting rakes (40), arranged spaced apart, with tiered supports (42) for brush bodies, and conveying rakes (41) which carry out a conveying movement from tier to tier. After said separating apparatus (25), the brush bodies are fed individually to a further processing unit. <IMAGE>

Filed: 1984-04-27
Abstract: A description is given of a device, which can be produced either as a slide or as a dial, for the rapid and simple determination of key signatures in sharps and flats, for transposition, and for determining the cadences of the associated scales. A first scale carrier carries, starting from a zero point, progressively in one direction the names of the intervals of the circle of fifths and progressively in the opposite direction, starting from the same zero point, the names of the intervals of the circle of fourths, and a second, displaceable scale carrier carries an identical second scale in its marginal zone facing the first scale carrier. Additionally arranged on the second scale carrier is a third scale which, starting from a zero point situated next to the zero point of the second scale, progressively carries in one direction the images of the key signatures of the circle of fifths and in the opposite direction, progressively, the images of the key signatures of the circle of fourths, and the arrangement is such that each of these images is arranged next to the name of a key assigned to this key signature. A third displaceable scale carrier carries the names of the ecclesiastical modes and serves to determine cadences and the interval chords.

Title: Chest of drawers with pull-out lock
Inventor: KRAENZLE WERNER
IPC: E05B65/464
Filed: 1984-08-25
Abstract: Accommodated in the cabinet carcass (1) of the chest of drawers are drawers (2, 3, 4), a blocking pillar (5) and a locking device (6) with a cylinder lock (7). The blocking pillar (5) is held on the cabinet carcass (1) by connection pieces (21) which non-rotatably bear an axle body on which actuating members (34) are guided longitudinally adjustably and rotatably and pressure members (35) are guided non-rotatably together with spacer members (36) which are again rotatable. A rack (49) attached to a drawer (2, 3, 4) engages in each case in the outer toothing of an actuating member (34). Axial cams are provided on the adjacent end faces of the actuating members (34) and pressure members (35), which axial cams lift all the members (35, 36 and 34) situated above a drawer when the latter is pulled out. As a result, the upper spacer member (36) is lifted into an annular lifting space up to a stop, thus preventing further lifting and pulling-out of a second drawer. When all the drawers are pushed in, a lock and an annular segment collar (54) can be pushed into the lifting space by means of the cylinder lock (7) thus blocking all the drawers in their closed position. The design of the pull-out lock as a blocking pillar is inexpensive and space-saving. <IMAGE>

Patent DE-3435684-A1 (DE)
Title: Cloth-beam drive for a weaving machine
Inventor: REHLING WALTER
IPC: D03D49/20
Filed: 1984-09-28
Abstract: A drive for the cloth beam of a weaving or knitting machine comprises an electromagnetically switchable friction coupling, the driving side of which is connected to the cloth draw-off rollers or to the drive of these and the driven side of which is coupled to the cloth beam. The current flowing through the electromagnet and therefore the torque transmitted by the friction coupling is set by a current controller as a function of a quantity dependent on the winding diameter, especially of the sum of the rotations of the cloth beam. It is thereby possible for the pull occurring in the cloth web to be automatically set constant irrespective of the winding diameter of the cloth beam. With a larger winding diameter, the lower coefficients of friction occurring in the friction coupling as a result of the higher slip speed and the saturation in the magnetic circuit occurring in the electromagnet of the friction coupling bring about an underproportional increase of the torque transmittable by the coupling in comparison with the current flowing through the electromagnet, so that the outer layers of the cloth web are wound somewhat less tautly than the inner layers. This effect is likewise desirable. A driving mechanism counts the rotations of the cloth beam, and an adjustment of the material thickness of the cloth web can be carried out by engaging and disengaging the driving pins.

Title: Four-stroke internal combustion engine with free pistons and linear drive forces
Inventor: STOPE DIETMAR DIPL ING
IPC: F02B75/02
Filed: 1984-10-22
Abstract: This four-stroke internal combustion engine comprises four annular working chambers acting in opposition to one another on one axis, which force a free piston to perform reciprocating movements. The faster the movements, the greater the piston stroke and hence the power. The free piston comprises two pairs of pistons, which are firmly connected to a piston rod passing through them. The piston rod is hollow and at the two ends outside the engine block is capable of transmitting the linear working forces directly as linear drive forces. Generators, pumps and compressors may be optimally driven by the piston rod and also generate rotary movements depending on the sphere of application.
