Patent DE-3117592-A1 (DE)
Title: Safety luminaire (lamp)
Inventor: BUSCH HEINZ DR
IPC: H01K1/34
Filed: 1981-05-04
Abstract: The invention relates to a luminaire for the electrical illumination of rooms which are filled with a medium which is at a higher pressure than the normal atmospheric pressure and which can also have a density deviating considerably from that of the normal atmosphere. Halogen tungsten filament lamps, in particular, have a very high temperature on the surface of their bulb, which is normally produced from quartz. If the atmosphere surrounding the bulb is at a higher pressure than the pressure in the bulb of the luminaire, the gases in the environment diffuse through the quartz bulb into its interior, and this happens, in particular, given the high operating temperatures. This process is typical in decompression chambers for deep divers, and is dangerous when after weeks these divers are decompressed in these chambers, ie. the pressure in these chambers is lowered once again to the normal atmospheric pressure. The atmosphere, consisting predominantly of light gases such as, eg. helium, then generates in the luminaires the pressure which can lead to the bursting of the lamps when the external pressure is lowered. There is a danger of fire and injury due to the hot splinters. The subject matter of the invention is a further quartz bulb, or glass bulb, which surrounds the luminaire bulb tightly, has at its surface only a low temperature, which is not capable of causing ignition in the case of most substances, which substantially reduces the diffusion into the interior of the luminaire bulb, and which discharges overpressures with respect to the surrounding atmosphere which occur in its interior to escape outwards via an overpressure valve on this jacket bulb.

Title: Gripper jaws for jaw chuck on machine tools
Inventor: SCHUNK JUN FRITZ
IPC: B23B31/16
Filed: 1981-06-10
Abstract: Gripper jaws on a jaw chuck of a machine tool are used for clamping a workpiece. They have adjustment jaws coupled to an adjustment device for radial adjustment of the jaw chuck, with a radial clamp toothing gripping the workpiece. If this clamp toothing is worn, damaged or unsuitable for the next operation, then it must be replaced. This replacement always entails, particularly in the case of heavy-duty machines, a considerable stoppage in production. According to the invention, the clamp toothing is therefore arranged on a separate clamp insert which is fitted in a rotationally fixed manner into an axial guide of the adjustment jaw and is held releasably by means of a safety device. <IMAGE>

Title: Double-belt press with sealing frame
Inventor: FIEDLER EWALD
IPC: B30B5/06
Filed: 1981-07-24
Abstract: A double-belt press is described, in which endlessly circulating belts are guided between pressure plates and receive the material to be pressed between them. In order to ensure that the pressure plates and the belt surfaces interlock in a pressure-tight manner, according to the invention a sealing frame is provided which is arranged between the pressure plates and the associated belts. The sealing frame is supported via sealing profiles opposite the pressure plates and has floating seals which project towards the belts and extend around the periphery of the sealing frame. Damaged floating seals can be replaced very easily by removing the sealing frame and inserting another sealing frame with new floating seals. Use of aluminium to produce the sealing frame makes it possible to ensure that both the floating seal and the sealing frame have the same coefficients of expansion, so that leakages can be avoided.

Patent DE-3134668-A1 (DE)
Title: Annular gear motor
Inventor: EISENMANN SIEGFRIED DIPL ING
IPC: F04C2/08
Filed: 1981-09-02
Abstract: In annular gear motors, in which the pinion meshing with the internal gear has only one tooth less than the internal gear, the internal gear teeth are normally defined by circular arcs or similar curves. Each tooth of the pinion is in constant engagement with a tooth of the internal gear. The invention improves the contact ratios, the sealing and other essential characteristics of the engine in that the teeth of the internal gear have an approximately trapezoidal shape with convexly curved flanks and tops. In this way the teeth tops of the pinion and the internal gear are only in sealing engagement with one another, no longer in driving engagement. The driving engagement between the internal gear and the pinion is produced exclusively between the tooth flanks, which are relatively steep due to the trapezoidal shape.

Patent DE-3208719-A1 (DE)
Title: Dynamo for cycles or the like
Inventor: MUELLER WERNER
IPC: H02K7/08
Filed: 1982-03-11
Abstract: The invention relates to a dynamo for cycles or the like, having a multi-pole rotor (2, 2a), which consists of permanent magnet material and is supported rotatably in a housing (1) with the rotor shaft (3) opposite at least one coaxially arranged coil system (4, 4a, 4b). The rotor shaft (3) is driven via a friction wheel (5) which engages on the side of the cycle tyre, a particularly favourable mechanical efficiency being achieved in that the rotor shaft (3) and the friction wheel shaft (6) are connected to one another by a coupling (7). In consequence, the rotor shaft can be supported correctly so that a considerably better mechanical efficiency is also achieved for a given dynamo drive power. It is also possible for there to be intermediate gears (11) between the friction wheel shaft (6) and the rotor shaft (3), and, in addition, such a dynamo is particularly easy to fit since the friction wheel part on the one hand and the rotor part on the other hand form separate fitment units which are not joined until they are finally fitted. <IMAGE>

Title: Method for simultaneously measuring the concentration of radioactive gases by means of a multi-layer scintillation chamber
Inventor: CHUDY MARTIN
IPC: G01T1/00
Filed: 1982-04-05
Abstract: The invention is related to a method for measuring the concentration of radioactive gases and enables the concentration of several radionuclides to be simultaneously determined. In this method, a gas containing several beta radionuclides is introduced into an independent chamber where its concentration is simultaneously and selectively determined by means of plastic scintillators. From the energy of the emitted beta radiation, individual radionuclides are identified and selectively and quantitatively determined by means of amplitude discrimination of the registered pulses. This method is carried out either continuously or discontinuously. The multi-layer scintillation chamber consists of a light-tight housing in which the plates of the plastic scintillators which have suitable dimensions and arrangements and are connected to photomultipliers by means of optical waveguides on both sides are located.

Title: Valve timing system for four-stroke reciprocating-piston internal combustion engines
Inventor: VALEV ASSEN DIPL ING DR
IPC: F02B75/02
Filed: 1982-05-17
Abstract: The intake and exhaust valves (1, 2) of a four-stroke reciprocating-piston internal combustion engine are actuated with the aid of cams (8) seated on the cam shaft (7) and of tappets (5, 6) interacting with the said cams. In this arrangement, each intake and exhaust valve (1, 2) is assigned an additional cam drive, which is provided with a rocker lever (9) engaging, at a point offset preferably by 180 DEG  relative to the point of engagement of the tappet, on the cam (8). This additional cam drive can be brought into action to increase the braking effect of the internal combustion engine or can be lifted off from the cam (8), a brake flap possibly being arranged in the exhaust pipe. In order to achieve a simplification in construction, to reduce the risk of wearing out and to reduce the inertia and spring forces occurring in the valve timing system, the tappet is also formed by a rocker lever (5) or a roller (6) mounted in the latter. Both rocker levers (5, 9) furthermore have angled arms (5', 9') which point towards one another, rest against one another with rolling surfaces (10, 11) for the transmission of motion and can be lifted off from one another. <IMAGE>

Title: Device for forming gaps between two groups of formed bodies in a continuously conveyed series of formed bodies
Inventor: KECK DIETER
IPC: B65G47/31
Filed: 1982-07-16
Abstract: The invention is characterised by a feeding belt and a discharging belt which are each made up of sub-conveyor belts arranged parallel to one another and at a distance from one another. The sub-conveyor belts share a deflection roller which is designed to be displaceable in a reciprocating manner, causing the sub-conveyor belts of the feeding and discharging belts to become engaged with one another and form a flat line in the area of the shared deflection roller. A first light barrier is arranged above the shared deflection roller in its initial position, while another light barrier is arranged at a distance equal to the length of a group of formed bodies behind the first light barrier in the direction of feed of the clay extrudate, and this other light barrier sends a readiness signal to the first light barrier. The first light barrier is connected in such a way that when the readiness signal has been received, the drive which moves the shared deflection roller in the direction of feed of the clay extrudate can be switched on and the speed of the discharging belt can be increased. A third light barrier is arranged at a distance behind the second light barrier in the direction of feed of the clay extrudate and this third light barrier connects another delivery device when the group of formed bodies reaches it. The distances between the individual light barriers are designed to be adjustable in accordance with the length of the groups of formed bodies and the distance between them, to enable the device to be set to other formed body formats.

Patent DE-3234172-A1 (DE)
Title: Surface-mounted probe for determining pO2 histograms
Inventor: SORGER PETER PROF DR RER NAT
IPC: A61B5/00
Filed: 1982-09-15
Abstract: A surface-mounted probe for determining pO2 histograms by means of a plurality of electrodes which are arranged in an insulating body and end in a mounting surface is characterised by the construction of the electrodes as films on insulating fibres, which arrangements are embedded in an insulating manner in a common cast (potted) member. This produces advantages with respect to production as well as, in particular, weight and the large number of electrodes which can be provided. It is preferable for the electrode front faces to be situated at the bottom of a recessed channel whose depth is of the order of magnitude of the thickness of the electrode film. This results in an improved diffusion geometry and in a low sensitivity of the measuring signal to the mounting pressure. The probe can be constructed in a design which is outstandingly capable of sterilisation by using a diaphragm which is directly applied and preferably arranged in the recessed channel, or also as a Clark type probe with an electrolyte chamber below the diaphragm. The latter construction is distinguished by a short run-in period and by long-term stability. The pressure sensitivity specific to this type is greatly reduced by the geometry of the recessed channel.
