Title: Transceiver capsule for locating kidnap victim - sends sos call via mobile relay and awaits command to send homing signal
Inventor: SCHREYER KARLHEINZ
IPC: G01S1/68
Filed: 1979-09-19
Abstract: A person liable to be kidnapped carries a small transmitter- receiver capsule (2) which can be activated by pressing a button and then swallowed. The capsule sends an emergency call, switches to receive on the same frequency for 4 seconds and repeats the cycle until it receives an acknowledgement signal. Then it switches to receive on a second frequency and awaits a command signal, whereupon it transmits a homing signal on the first frequency. The sequence is designed to conserve the capsule battery while a rescue is organised. Signals are received from and sent to the capsule by a mobile relay station, (1) which may be installed in the person's own car. A group of monitoring stations, with land line connections to a central control (16), receive signals from the relay and locate its position. The monitors send acknowledgement and command signals to the relay when so instructed by the control centre.

Title: Gear train backlash take=up equipment - has discs coupled by spring and sliding radially when turned
Inventor: BAEHRING HORST DIPL PHYS
IPC: F16H1/32
Filed: 1980-03-29
Abstract: The equipment takes up any backlash between two intermeshing gears in a gear train which is self-locking under the effect of torque on the output side. A first disc slides radially on a spindle concentric to one of the gears, and is so coupled to a second disc that this sliding movement takes place when they are turned in relation to each other. A driving mechanism is coupled via the spindle to a gear so as to turn it in relation to the other gear when rotated in either direction. When the gears start to seize, one of the discs slides so as to increase the backlash between them slightly. A spring coupled between the discs turns them in relation to each other so as to increase the relative radial sliding movement, thus taking up the backlash between the gears coupled to them.

Title: Refining of molten tin for removal of arsenic - by adding manganese alloy, which combines with arsenic to form foam which is sepd. from melt
Inventor: SUTURIN SERAFIM N
IPC: C22B25/08
Filed: 1980-04-30
Abstract: Tin is melted and heated to 250-600, esp. 280-360 deg.C. A manganese cpd. is then added using a ratio of Mn:As in the tin of 0.5:1 to 2:1. The Mn cpd. reacts with the As to form a cpd. which is removed from the melt to leave pure tin. In the pref. process, a Mn alloy is pref. added using a ratio Mn:As of 05-0.9:1 with sepn. of the Mn-As cpd., and then adding a second batch of the Mn alloy using a ratio Mn:As of 1.3-2:1, followed by further removal of the Mn-As cpd. obtd. The molten Sn is pref. covered by a carbonaceous material, esp. wood chips or coal; or a gas, esp. N2, may be blown through the melt after adding the Mn alloy. The amt. of tin lost in removing the As is reduced, and toxic arsine is not formed by the metal foam contg. the Mn and the As.
Patent DE-3018222-A1 (DE)
Title: Safety circuit for cigar lighter - short circuits power supply to blow protecting fuse in case of overheating
Inventor: BAUERNFEIND OLAF ING GRAD
IPC: B60N3/14
Filed: 1980-05-13
Abstract: The object of the proposed circuit interruption system is to prevent overheating of the cigar lighter body. When pushed into its socket (2) against the action of a spring (7') the heating element (8) of the lighter engages with the hooked ends (9') of two bimetal strips (9) connected to the supply (11). At the set temperature the strips expand and release the latch and the lighter springs clear of the electrical contacts. Should the spring fail, the bimetal strips fail, or the lighter be otherwise prevented from moving then current is fed to it by a second set of bimetal strips (15, 15'). Their mechanical action is to grip the element (8) tighter as they heat up. This improves the heat transfer from element to strip. This heat is conducted by the electrical connection (10) past the ceramic base insulator (12) to a fusible insulator (13). Should the fusible insulator melt a spring contact (14) is released to connect the supply (11) to earth on the socket (2). The associated fuse then operates to clear the circuit and prevent any further heating.

Title: Reconstituted thermoplastic sheets prodn. - in which assorted film waste is reduced, mixed, hot-pressed between cauls and cooled to release
Inventor: ZIMMERMANN ERICH L
IPC: B29B17/00
Filed: 1980-06-27
Abstract: Thermoplastic materials, and partic. waste, is reconstituted into sheets by measuring out, distributing over an area, and densifying hot. The material is reduced and laid between two metal cauls at over 120 deg.C (pref. over 200 deg.C); it heats up and is pressed at 6 kp/cm2, air is removed, and the controlled-dimension sheet is cooled under pressure to permit release from the cauls. Various polymers can be used without binder, prods. are dense, rigid, physiologically neutral sheets suitable for use in drainage/soil improvement, process can use e.g. bag scrap. In the plant a conveyor passes to and through a hot and a cold press, both working at over 6 kp/cm2. Different kinds of scrap thermoplastic materials are reduced and mixed together beforehand, fed on to a bottom caul, and distributed evenly. A second press caul is laid on top. The conveyor moves this press load stepwise into the hot press, occluded air in the material escapes from between its (e.g.) strips. The cauls adhere to the densified sheet produced, and a subsequent cooling station is therefore necessary for their release.

Patent DE-3029838-A1 (DE)
Title: Measuring gas pressure using resonant sound propagation dependency - controlling input-output phase difference by varying frequency to derive pressure from frequency
Inventor: THOMA ANDREAS DR
IPC: G01L11/04
Filed: 1980-08-06
Abstract: The measuring method involves using the dependency on pressure of the propagation of sound over a measurement path. It enables a high degree of sensitivity to variations in gas pressure to be achieved. The phase difference between the input and output signals in the measurement path is measured in the resonant region by regulating the phase difference to a fixed value using frequency adjustment. The frequency is then used as the measure of pressure. Alternatively, the phase difference in the linear or approximately linear phase variation region directly about the resonant point, or in the non-linear region adjacent to it, is used as the measure of the pressure. By operating in regions of resonance, large variations of phase with pressure are achieved.

Patent DE-3048975-A1 (DE)
Title: Reduced removal rate of filter aid on vacuum drum - with constant pressure in adjacent internal cell (NL 16.07.82)
Inventor: DAMMAN BERNARDUS J
IPC: B01D33/09
Filed: 1980-12-24
Abstract: Suspensions difficult to filter are filtered on passage through a thick layer of filter aid on the surface of a vacuum filter drum which rotates while partly immersed in a bath of the suspension. The drum interior is divided into separate cells individually connected to suction lines. Outside the drum is a scraper for gradually removing the filter aid surface. Pressure in the drum cell nearest to this scraper is kept constant at a level appreciably below that in the other cells. Should the level of suspension in the vat be lowered, the rate of filter aid removal is automatically reduced, by adjusting the cutter, e.g. to less than 5 mm per hour, while at high suspension levels the removal rate can rise to 10 mm per hour. The appts. is also claimed. Suitable e.g. for 75 wt.% phosphoric acid contg. arsenic sulphide, using calcined Kieselguhr as filter aid. Scraping of the layer, now related to the extent of clogging rather than the number of rotations of the drum, is reduced. In an example, 400 cu. metres of phosphoric acid were filtered before the layer was exhausted, compared with 90 cm metres by the known appts.

Title: Lifting device for a vertically adjustable seat
Inventor: KLUETING BERND ING GRAD
IPC: B60N2/18
Filed: 1981-01-19
Abstract: The lifting device for a vertically adjustable seat, in particular a vehicle seat, is arranged between the floor of the vehicle and the seat and is to permit a two-stage vertical adjustment of the seat component, the seat component reliably remaining fixed. For this purpose, a support element is held longitudinally displaceably on a rail fixed to the floor of the vehicle, in which support element an eccentric cam is rotatably mounted, which cam engages with an eccentric pin in a supporting bracket arranged on the frame of the seat component. The eccentric pin can be displaced in a horizontal guide and, during the rotation of the eccentric cam, lifts the supporting bracket with respect to the supporting element held on the guide rail. Such a lifting device is arranged on both longitudinal sides of the seat component, in particular in its rear seat area and serves to raise and adjust the angle of inclination of the seat component. However, a lifting device of this kind can be arranged at any corner area of the seat component, the lifting devices which lie opposite one another being combined in the rear seat region and in the front seat area by a transmission tube to form a control unit.

Patent DE-3113416-A1 (DE)
Inventor: SOMMERS HANS DIPL ING
IPC: F23D14/00
Filed: 1981-04-03
Abstract: The method and apparatus sucks the entire combustion air volume in laterally with respect to the direction of flow of the air current with the help of the impulse of a fuel gas jet out of the air current into a mixing pipe and the formation of a differential pressure between the mixing pipe input and the waste gas output into the air current is prevented with the help of current guidance sheet metal pieces. The burner is arranged in a shaft-like housing, the fuel gas nozzle and the lower part of mixing pipe are surrounded by a pot-shaped current guidance sheet metal piece. A cylindrical current guidance sheet metal piece adjoins the cooled burner plate. The burner which, for example, can be used in dryers, for heating room air with so-called make-up air units and in gas water heaters, operates completely independently of the air flowing around it in a wide heat load range, without any change in the air coefficient. Because of the super-stoichiometric premixing of the burning gas with the air, the NOx content of the waste gas is extraordinarily small.

Title: Method for testing echo suppressors
Inventor: FRUEHAUF RAINER
IPC: H04B3/493
Filed: 1981-05-27
Abstract: The invention relates to a method for reducing the testing time for echo suppressors which contain timers with long time constants. In modern exchanges, echo suppressors are checked automatically as a matter of routine. Since the echo suppressors contain control units with timers, for example in the controller for phantom telephony (2) and use further timers to test specific levels, the timers are in any given condition when a connection is cleared down. Defined levels are applied with the test. It has, however, hitherto been necessary to wait until the timers and the adjustment and control devices which are dependent on them have switched to the idle position. In the invention, the timers are reset at the start of the test and, if necessary, also between the individual test stages in combination with the disablement of the echo suppressor. This considerably reduces the testing time. No additional echo-suppressor control input is required for resetting purposes. <IMAGE>

Title: Device for producing thermoformed mouldings from plastic sheet
Inventor: KOESTER WERNER
IPC: B29C51/42
Filed: 1981-05-30
Abstract: The aim is to construct a device for producing thermoformed mouldings from plastic sheet such that no distortion of the plastic sheet can occur in carrying out the individual conveying steps thereof, which distortions might impair a printed image which may be located thereon. The device for producing thermoformed mouldings consists of a moulding station with an integrated or downstream punching device and of a sheet heating device which is arranged upstream of the moulding station and heats the film regions to be formed and of a film cooling device which keeps the film waste regions cold. At least the film cooling device is arranged so as to be raisable and lowerable with respect to the conveying plane of the plastic sheet and can therefore be removed during the transport steps of the plastic sheet sufficiently far therefrom to avoid frictional stressing of said plastic sheet. The sheet cooling device can be raised and lowered synchronously with the lower mould of the moulding station and a cooling frame can be additionally allocated to it, which cooling frame surrounds the heating zones of the sheet heating device and in its contours corresponds to the contours of the cooling webs on the sheet cooling device.
