Title: Safety device on short-barrelled and long-barrelled weapons having a slide catch release, especially a self-loading pistol
Inventor: KUECKENS ALEXANDER
IPC: F41A17/74
Filed: 1981-08-14
Abstract: In order to simplify the handling of a short-barrelled weapon (revolver, pistol) or a long-barrelled weapon (shotgun, rifle) having a slide catch release, the normal weapon safety device is constructed in such a manner that the safety element, including its operating part, is arranged on the slide catch release (4) itself, in accordance with Figure 2. In this case, the safety element can be constructed with its operating element as an integral safety part (12), which can pivot about a transverse axis (18) of the slide catch release (4), has a striking surface (23) which, in the armed position, transmits the striking force of the slide catch release (4) directly to the rearward end (15) of the longitudinally displaceable firing bolt (6) and which, by means of an operating section (19), can be pivoted in the clockwise direction from the weapon safe position which is shown in Figure 2 into the armed position. In the safe position according to Figure 2, a recess (22) in the unit which consists of the slide catch release (4) and the safety part (12) is aligned with the end (15) of the firing bolt (6), so that said slide catch release is prevented from having any influence on the firing bolt (6). <IMAGE>

Patent DE-3200051-A1 (DE)
Title: Rock-stabilising cartridge
Inventor: DRESPA GERD
IPC: E21D9/00
Filed: 1982-01-04
Abstract: Rock-stabilising cartridges consist of at least two chambers which are filled with different adhesive mixtures which foam together upon destruction of the chamber walls, the destruction device for the chamber walls being arranged inside the chambers and being firmly connected to the chamber walls at the top chamber ends and being passed through the base or the closure of the chambers. The chamber walls are torn open and destroyed via the destruction device, which as a rule consists of a tearing wire having two ends, so that the two components can be mixed together and can react with one another. In the process, the mixing action is additionally assisted by the torn chamber walls being pulled through the two components in such a way that the latter are whirled up. <IMAGE>
Patent DE-3202581-A1 (DE)
Inventor: FRANK WOLFGANG
IPC: B29C70/00
Filed: 1982-01-27
Abstract: Method for the production of a flat prefabricated element, particularly a sailing board, from a prefabricated foam core and two half hulls attached to said core and to each other. At the joining line of the two half hulls, the foam core has a smaller size than the preset size. The resulting empty space between the foam core and the two half hulls is filled with a molding material after closure of the negative mold. Thereby, when closing the negative mold, the foam is prevented from overflowing at the joining line, which could hinder a further welding of the edges of the half hulls. Furthermore, owing to the reinforcing effect of the molding material, the joining line is made shock resistant, thereby eliminating any risk of splitting, even if the prefabricated element is subjected to severe strains.

Patent DE-3210591-A1 (DE)
Title: System for continuously measuring the bubble content of hydraulic fluids
Inventor: STANG WOLFGANG DIPL ING
IPC: G01N29/032
Filed: 1982-03-23
Abstract: To continuously detect or measure gas bubbles in stationary or flowing hydraulic fluids, use is made of an ultrasonic head operating as a transceiver to transmit pulses in the MHz range into the medium to be examined. Said pulses produce temporally defined echoes on staggered reflectors and are picked up again by the ultrasonic transducer. In the case of a bubble-free fluid, said echoes are virtually undampened, whereas the echo amplitudes decrease with increasing bubble content. The measurement sensitivity and the measurement range depend, inter alia, on the length of the measurement path or the sound transit time and can be set to meet the requirements by means of a suitable number and arrangement of reflectors (see Figure 1). The electronic processing from the pulse generation to the bubble content display is carried out in a suitably equipped ultrasonic device.

Patent DE-3211257-A1 (DE)
Title: Image position detector
Inventor: MATSUDA MOTONOBU
IPC: G02B7/30
Filed: 1982-03-26
Abstract: An image position detector contains a light pick-up element (20) which receives an image from an object in order to generate electrical signals caused by this image, furthermore a signal processing circuit (CKT1) which processes the electrical signal and produces a position signal corresponding to the position of the image on the light pick-up element (20). The light pick-up element (20) is formed by a semiconductor device consisting of an n-type substrate (22) with a p-type area (24, 26) formed on the substrate. The current produced between n-type substrate (22) and p-type area (24, 26) is related to the distance of the image from the p-type area. The signal processing circuit (CKT1) receives the generated current and thus determines the position of the image on the basis of the magnitude of the current generated. <IMAGE>
Patent DE-3217906-A1 (DE)
Title: Thermal wave generator for imaging thermal structures
Inventor: BUSSE GERD DR
IPC: G01N25/72
Filed: 1982-05-12
Abstract: The invention relates to the generation of thermal waves for an imaging method, in which structures of objects are detected by their effects on the propagation of thermal waves. The thermal waves are generated by periodically feeding heat to and also removing it from the object (5). As a result, a net heating of the measurement object is avoided. One possible realisation of the method according to the invention consists in using a Peltier element (1) to generate the thermal wave. <IMAGE>
Patent DE-3218362-A1 (DE)
Title: Electronic special drive circuit
Inventor: MERKLE PAUL
IPC: H03K19/20
Filed: 1982-05-15
Abstract: The subject matter of the invention is the idea of using, instead of a normal AND gate or instead of a simplified AND gate (transistor), a more simplified AND gate which, in the simplest case (Figure 1) only consists of a diode which is arranged in the reverse direction in the drive input. Naturally, this principle can only be applied in individual cases because the potential source which drives the input a must not be used for driving other inputs and thus also must not drive input a in another AND gate according to Figure 1. In type B of this AND gate having two inputs (Figure 3), a negating circuit (2) is also additionally arranged in the predrive input b, which circuit is only shown as a switching symbol. According to Figure 5 and 7, multiple circuits are also possible in accordance with this principle. <IMAGE>
Patent DE-3221399-A1 (DE)
Title: Data acquisition system for vehicles
Inventor: SPAUSZUS SIEGFRIED
IPC: G07C5/08
Filed: 1982-06-05
Abstract: In the vehicle (1), an acquisition device (2) is mounted into which a cassette (3) having a data memory (22) can be inserted. On the other hand, the cassette (3) can be inserted into a data reader (4) in the office of the fleet depot in order to transmit the data from the cassette (3) to a computer (5). The data acquisition device (2) is constructed in such a manner that it is equipped with a multiplicity of transmitters (19) which check the various functions of the vehicle and supply data on these. To be able to correlate this data in time, a clock (23) with a time of day and date display is also arranged in the data cassette (3), which enables the data recorded in the data memory (22) to be correlated in time. Arranging the clock (23) in the cassette (3) instead of in the data acquisition device (2), as would be the obvious case, has the advantage that all acquisition devices of a fleet depot can be continuously checked for synchronicity via the computer (5) or via the data reader (4) without this requiring any manual or visual check. <IMAGE>

Title: Method for decoding a stereophonic signal
Inventor: SAARINEN PERTTI VIHTORI
IPC: H04N5/60
Filed: 1982-07-17
Abstract: Method for decoding a stereophonic signal in a television receiver, the information of one channel being the sum (R + L) of the right-hand sound signal (R) and of the left-hand sound signal (L) and the information of the other channel being twice the right-hand sound signal (2R). By summing the incoming signals (R + L, 2R), two side channels are formed in such a manner that the second one in each case is inverted and the correlation interference of the side channels disappears completely. A centre channel can be formed which is equal to the incoming sum signal (R + L). <IMAGE>

Title: Fast-drive device for a high-speed earthing switch
Inventor: WESTBROCK PAUL DIPL ING
IPC: H02B13/075
Filed: 1982-07-22
Abstract: A high-speed earthing switch for a gas-insulated, encapsulated switching installation, especially for an SF6 high-voltage switching installation, has moving contact pins (12, 14) which, in the event of a defect, must be moved very quickly onto phase conductors (32) which are located inside the encapsulation (30) of the switching installation and are at high-voltage potential, in order to earth them. In order that the switching-on process can be carried out more quickly, the drive device has a piston/cylinder arrangement (50, 36) whose piston (50) divides the cylindrical space into two mutually connected sub-spaces, of which one sub-space is connected to the encapsulation (30) while, on the other hand, the other sub-space can be suddenly evacuated in order to switch the high-speed earthing switch on. When this other sub-space is rapidly evacuated, then the piston is set in motion into the switched-on position of the high-speed earthing switch. <IMAGE>

Patent DE-3301392-A1 (DE)
Title: Rim-mounted snow clamp
Inventor: STROTTNER KLAUS
IPC: B60C27/04
Filed: 1983-01-18
Abstract: In order to shorten the expenditure in terms of time and work - since it is no longer necessary to fit chains and other objects around the tyres - the rim-mounted snow clamp has the following technical features. The car-tyre safety device for snowy weather is installed in the rim. With a small number of rotations of a crank, the steel clamps are pushed out of the rims, constructed for this purpose, over the tyres via a thread and are pressed tight there. In principle, the same process is the automatic operation of the rim-mounted snow clamp by means of oil or air pressure. Here, the steel clamps are pressed out of the rim sheaths via small pressure and compression cylinders using the engine power of the car; the power transmission occurs via pressure lines to be installed and the device is controlled from the inside of the car. The rim-mounted snow clamp eliminates the need to carry the customary winter equipment for car tyres separately and dispenses with fitting it which is time-consuming and laborious.
Patent DE-3310312-A1 (DE)
Title: Device for heating mud flaps to prevent blocking of the steering by snow and ice
Inventor: STELZ BERNHARD
IPC: B60H1/00
Filed: 1983-03-22
Abstract: The problem of de-icing mud flaps in the winter, where chunks of snow and ice have formed and snow accumulates further during driving, can be solved by means of the environmentally friendly mud flap heating device which is heated by the radiator water. By heating up the mud flap at the corresponding points, renewed accumulation of snow is made impossible. The vehicle wheel can thus move unimpeded and the steering is no longer blocked. The radiator water which is heated by the engine serves as a heat energy source. The design is simple and economical. The heating device for mud flaps for preventing the blocking of the steering by snow and ice can be installed in virtually any motor vehicle.

Title: Safety switch for removable protective caps, doors, flaps or the like
Inventor: WECKE ROLF DIPL ING
IPC: F16P3/08
Filed: 1983-04-08
Abstract: The safety switch (2) consists essentially of a switch housing (3) and an operating device (4). A sleeve (5), which is secured by means of blocking balls (10), is arranged in the switch housing (3) such that it can be displaced longitudinally. Located in the sleeve (5) is a bolt (12) having an annular groove (14) which can be pushed so far into the sleeve (5) by means of the plunger (19) of the operating device (4) that the annular groove (14) is located in the region of the blocking balls (10). In this position, a bead edge (22) of a clamping sleeve (20) which surrounds the plunger (19) concentrically snaps into an undercut (17) in the sleeve (5), in a positively-locking manner. By means of further axial pressure on the sleeve (5), the blocking balls (10) can now turn aside into the region of the annular groove (14) of the bolt (12), so that the sleeve (5) can be displaced axially. The front end of the clamping sleeve (20) is in this case displaced into the bearing hole (6) within which the sleeve (5) is guided. It is not possible to separate the operating device (4) from the switch housing (3) again until the sleeve (5) has been drawn so far out of the switch housing (3) that its position is secured by means of the blocking balls (10). <IMAGE>
