Patent DE-3608991-A1 (DE)
Title: Impact-surface drive system
Inventor: RAEHMER HANS
IPC: B64C33/02
Filed: 1986-03-18
Abstract: The useful power from an impact-surface propeller is considerably improved by means of active, that is to say motor, operation of the rotary impact. This has become possible for the first time using the means and circuits shown. Surprisingly, fluid systems, such as pneumatic and hydraulic systems, have been found to be particularly suitable for such a rotary impact drive, which appears to be curious when first considered. Hazardous flying situations, which could otherwise result in the case of rigid coupling, can be avoided by means of a quasi "non-galvanic" coupling of the drives from the parallel impact and rotary impact, with specific coupling elements in the circuit, if a rocker is held firmly, for example, in the limit position. This can in turn be used as an air brake. Using the means according to the invention, the thrust effect of such a drive can be adjusted, by means of phase shifting, from pure forward drive to pure lift. <IMAGE>

Title: Method and apparatus for lowering round shaft covers into road surfaces
Inventor: RUPPRECHT RICHARD
IPC: B28D1/18
Filed: 1986-12-08
Abstract: A method for lowering shaft covers into road surfaces proposes the following working steps:   - milling a slot in the spacer ring (D) or conduit shaft (K) located below the shaft ring (R) to be lowered, - insertion of spacers or the like, which correspond to the amount to be lowered, into the milled-out slot, - lowering of the shaft ring (R) until it bears against the inserted spacers, and   - filling of the remaining slot with a suitable filling material. A disc-type milling cutter 7, which engages in the shaft wall of the conduit shaft K, is driven by a vertically arranged shaft 6 and guided once around the circumference of the conduit shaft K by means of a suitable apparatus inside the shaft ring R. Spacers which correspond to the amount to be lowered are inserted into the slot which is milled out with overmeasure. After the shaft ring R has been lowered onto the spacers, fast-setting rigid foam plastic of sufficient load-bearing capacity is preferably injected into the remaining slot. Appropriate apparatuses for milling the slot in the shaft wall and for lowering the shaft ring R onto the inserted spacers are described. When working in accordance with the method according to the invention and using the apparatuses described, a single shaft ring can be lowered by a single road construction worker without complication in approximately two hours.

Title: Forging machine
Inventor: SCHMOLL HEINZ
IPC: B21J13/03
Filed: 1986-12-17
Abstract: On forging machines with, in particular, four rams arranged in an X in one plane, offset by 90@ relative to one another, acting radially on the workpiece, fitted with dies (57) and executing the working stroke, the rams are designed as part (reciprocating part) of a piston-cylinder unit (42, 45), the second part (45) (adjusting part) of which, which delimits the displacement volume in the direction of the reaction pressure, can be adjusted axially relative to the machine frame (43) (fixed part) by the adjustment travel (stroke-position adjustment) which remains when the working stroke is subtracted from the total stroke. The invention aims to achieve improved, relatively play-free ram guidance, overcoming the disadvantages which arise from the separation of the drives for the working stroke and the stroke-position adjustment. According to the invention, the rams (42) are guided directly in the machine frame (43) (fixed part) as one part (reciprocating part) of the piston-cylinder unit (42, 45). The rams can be designed either as pistons guided in fixed cylinders with plugs adjustable in the cylinders as adjusting parts or can be designed as cylinders (42) guided in the machine frame (43) with pistons (45) supported in axially adjustable fashion on the machine frame (43) as the adjusting parts. <IMAGE>

Patent DE-3739689-A1 (DE)
Title: Helically coiled evaporator
Inventor: FISCHER GUENTHER
IPC: F28D7/02
Filed: 1987-11-24
Abstract: By comparison with the evaporators used so far in liquid cooling, the helically coiled evaporator eliminates the design-induced disadvantages. It can be produced very cost-effectively, since its manufacture is favourable in terms of outlay on both time and material. Furthermore, it can be cleaned easily and arranged in a space-saving fashion owing to its low overall size. Inside the refrigerant (evaporant) battery, the refrigerant is conducted through the inner tube (comparable to a capillary line) as far as the front end of the refrigerant battery. The evaporating process begins there. The refrigerant is fed back inside the refrigerant battery in the outer tube as far as the starting point. The refrigerant battery is inserted into an outer jacket in which the liquid medium to be cooled effects exchange of heat with respect to the refrigerant using the counterflow method.

Title: Production of casting compounds for electronics
Inventor: BURGER HANS-JOACHIM
IPC: B29B11/16
Filed: 1988-04-22
Abstract: In the previous processes for producing casting compounds for electronics, detrimental sedimentation effects occur. Therefore, the production of casting compounds for electronics is to be improved in such a way that they can be stored well and in a simple manner and, at the same time, no sedimentation of their fillers occurs. The said object is achieved by using for production of the casting compound a resin component and a hardening component which crystallise at room temperature and become low in viscosity when heated to relatively high temperatures. A filler is added to the two components in the heated, low-viscosity state. The heated, filled resin and hardener component is cooled for recrystallisation in sheet form. Casting compounds for electronics are used, for example, for sheathing heat-generating and/or fragile components or assemblies.

Title: Drive arrangement for the gripper arm of a tool-change device
Inventor: GLASS WOLFGANG
IPC: B23Q3/155
Filed: 1988-05-13
Abstract: Drive arrangement for the gripper arm of a tool-change device on machine tools, in particular machining centres. The gripper arm is accommodated on a shaft in a rotationally locked and axially displaceable manner and is connected to a double-acting piston arranged in the shaft. The shaft can be set in rotation by a double-acting working cylinder via a rack-and-pinion drive. The passages starting from the pressure spaces on both sides of the piston lead out axially symmetrically at the surface of the shaft. They are connected to two spatially fixed lines which, via a valve which can be reversed by the piston in its reversal positions, are connected to two lines leading to the pressure spaces of the working cylinder. The admission of pressure to one piston side automatically leads to the lifting, swivelling and retraction of the gripper arm.

Title: Satellite communications system
Inventor: REIDEL BERTHOLD
IPC: H04B7/185
Filed: 1988-07-18
Abstract: In meshed (networked) satellite communications systems in which every earth station can work with every other earth station, very different earth stations, i.e., for example, large radio stations and mobile earth stations, are often used. In order to safeguard transmission, maximum power has hitherto been transmitted according to the prior art from the respective transmitting earth station to the satellite for each connection between earth stations. In the case of a multiplicity of RF carriers, comparatively high intermodulation noise is produced, because the satellite transponder is then being operated close to its saturation point. According to the invention, the transmission power of the earth stations is set according to the antenna diameter of the respective receiving earth stations in order to reduce the transponder transmission power. <IMAGE>
