Patent DE-3024966-A1 (DE)
Title: Igniter assembly for explosive shell - has plunger with two locking systems released by spin, and has striker holder released on impact
Inventor: BACKSTEIN GUENTER
IPC: F42C9/18
Filed: 1980-07-02
Abstract: The nose cone (22) for an explosive shell has a small charge (29) at the rear, preceded by a detonating charge (23). The latter is mounted in a cylinder (20) which can be tilted to bring it into alignment with a firing pin (16). The pin can be forced into contact with the detonating charge when a plunger (11) is forced backwards by a spring (13) in the nose, on impact. The plunger is prevented from operating in advance by vibration or shock by a system of locking balls (6,9). The cylinder is prevented from rotating by an axial pin (18) with a hollow interior holding a spring (19), which remains in a locking position in a groove in the cylinder until released by impact. The locking balls also travel along a system of sloping channels (e.g.7) due to the spin of the shell after firing so that the plunger is released. A second device also released by the spin is a band (1) supported by carriers (2,3) wound around the plunger.

Patent DE-3130670-A1 (DE)
Inventor: WILLIMCZIK WOLFHART DIPL ING
IPC: F01C1/34
Filed: 1981-08-03
Abstract: The displacement feed machine used as a pump, compressor or similar is in principal assimilated to rotary slide and palette machines, except as to the cylindrical piston which is replaced by an annular piston (1) arranged in an annular chamber delimited by inner walls (3) and outer walls (4) which divide said annular chamber into two working chambers (2) and which rotate, roll or are at rest, when the radial walls of the working chamber are in motion. A circular cylindrical piston may move between the radial walls of the working chamber, which generate the working volume, which may form a monoangle, a biangle or a triangle, but which always have the same smallest radial distance. Thus, the drive elements (12) (slides (14) or cylindrical rollers (13)) arranged in the radial recesses (11) of the piston (1) have a compulsory motion. The piston is fixed to at least a side member (5). By cancelling the centrifugal forces, this machine behaves as a rotary piston machine. On each side of the piston there is arranged a working chamber, thereby providing a two-stage machine, which do not have to be necessarily always in working conditions; the compulsory motion and the cancelling of centrifugal forces are preferred per se. Inversely, a piston (monoangle, biangle, triangle...) which generates the working volume, may rotate between circular cylindrical walls. A pump with excentric rings is characterized by an annular piston which rolls simultaneously on both annular walls. A resilient wall may be arranged between the piston and the crank case thereby providing a sealingly closed pump which resists to abrasive agents. The horseshoe-shaped piston may be stationary and the resilient walls may be driven by an excentric.

Title: Electrically drivable optical modulator
Inventor: EICHWEBER KURT
IPC: G02B26/02
Filed: 1981-08-06
Abstract: An electrooptical modulator consists of a reflector having a reflecting flexible diaphragm, e.g. made from metallised electret foil, which is supported in matrix fashion and has therebetween non-supported areas which can be deflected into a configuration, which reflects the incident radiation in a scattered manner, by generating an electrostatic field in time with a modulation signal, with the result that the intensity of the reflected bundle of radiation is modulated. The reflector is preferably arranged in a parallel optical beam path together with filters or diaphragms which intercept radiation reflected in a scattered fashion. The modulator is suitable in principle for optical radiation of any wavelength, as well as for radiation in the submillimetre range, can be designed with a large area, and can be operated at a high modulation frequency or high bit rates and with a high modulation efficiency.

Patent DE-3132921-A1 (DE)
Title: Method of determining the wear of the tool in an NC machine tool, in particular an NC lathe
Inventor: RINN JUERGEN DIPL ING
IPC: G05B19/401
Filed: 1981-08-20
Abstract: A measuring station is approached in succession by the tool and the workpiece measuring feeler. Then the difference in the positions during this approach to the measuring station is formed. If the measuring station is approached in the same way twice after use of the tool and the corresponding difference formed, the difference between both differential values corresponds to the tool wear. This measuring method automatically eliminates thermal expansion in the machine tool. Instead of the workpiece measuring feeler, a calibrating tool which is not subject to wear can also be used.

Title: Process for coating the interior surface of handrail profiles or the like made of plastic with a contact adhesive, and handrail profile or the like produced according to this process
Inventor: OEPEN KARL-HEINZ
IPC: B29C44/12
Filed: 1981-09-24
Abstract: A handrail profile or the like formed from plastic, in particular polyurethane integral flexible foam, is to be provided with a contact adhesive layer on its interior surfaces, which contact adhesive layer brings about simple and secure bonding to a bannister rail. In a process for coating the interior surfaces of the handrail profile or the like, the contact adhesive layer is introduced into the profile mould, before or during the moulding operation, by means of a protective film which bears against the mould walls effecting the shaping of the interior surfaces and is easily releasable from said contact adhesive layer. It is important in this that the contact adhesive layer is embedded between the easily releasable protective film and a support layer which is difficult or impossible to release and the support layer is adjusted for an intimate bond to the curing plastic. For this purpose the support layer may consist not only of talc and/or fibre materials, for example crêpe paper, but may also be formed from an aluminium foil or a plastic film, for example PVC, polyester or polyamide.
Patent DE-3138406-A1 (DE)
Title: Process for sealing coke ovens, and an elastic coke oven door
Inventor: STOG WILHELM
IPC: C10B25/06
Filed: 1981-09-26
Abstract: The sealing of the lateral orifices of horizontal chamber coke ovens is particularly important for both plant engineering and ergonomical as well as environmental reasons. Uniform and reliable sealing can be achieved by means of a process for sealing horizontal chamber coke ovens from the atmosphere, wherein the required contact pressure is transmitted via the locking bolts and locking hooks directly into the chamber frame. This controlled transmission, limited to a narrow region of the coke oven door, of the contact pressure can be achieved particularly easily in the case of a coke oven door in which the number of joints and joining elements between the door body and the chamber frame is substantially increased, and in which the door body consists only of the diaphragm serving as the sealing plate and the sealing edges as well as the contact pressure element and in which the contact pressure element itself is associated with the edge of the sealing plate and is formed as a circumferential hollow body of variable volume, surrounded by a U-profile. This hollow body attached directly above the sealing edge allows the contact pressure to be uniformly applied and introduced into the chamber frame. <IMAGE>
Patent DE-3139686-A1 (DE)
Title: Flexible connection between a piston and a connecting rod
Inventor: DERER ANDREAS
IPC: F16J1/14
Filed: 1981-10-06
Abstract: The invention is a further development of piston technology in automotive construction and is designed to save fuel. The known pistons are connected to the connecting rod by means of a continuous pin in such a way that the length of the piston/connecting rod unit remains virtually constant. The result is that, in the lower engine speed range of a carburettor engine, when only a small amount of mixture is drawn in, the compression is insufficient. If, on the other hand, as provided by the invention and illustrated by the figures (1 and 2), springs are fitted in a particular way instead of the continuous pin, the compression in the lower engine speed range can be adjusted to a higher level without becoming too high in the upper speed range. As a result, carburettor engines require less fuel. However, in addition, the springs also have the effect that the exhaust gases are expelled more completely and that the fuel mixture is drawn in more efficiently. Furthermore, the springs take up inertia forces of the piston at the dead centre positions and subsequently release these again. These properties have an advantageous and fuel-saving effect in fuel-injected engines too. <IMAGE>
