Patent DE-3839262-A1 (DE)
Title: Mechanical pendulum-weight lever-drive
Inventor: BAUMER ALFONS
IPC: F03G3/06
Filed: 1988-11-21
Abstract: Driving machines which are difficult to start has hitherto been problematic since in relation to the starting power energy- and cost-intensive driving mechanisms have had to be constructed. By virtue of the invention of the mechanical pendulum-weight lever-drive, energy-generating machines which are difficult to start can be driven cost-effectively and in an energy-sparing manner. Furthermore, the unrestricted siting of power-provision mechanisms is to be mentioned as well as the environmentally friendly nature of these mechanisms.

Title: Method and apparatus for removing liquids specifically lighter than water from open stretches of water
Inventor: KALBANTNER EDGAR
IPC: E02B15/04
Filed: 1989-03-22
Abstract: A method of removing liquids specifically lighter than water, such as, for example, mineral oil, benzene, petroleum, benzol, is distinguished by the fact that a funnel-shaped hood open at the bottom is put into the water contaminated with the liquid, and the hood is then plunged so deep into the water that the water level inside the hood is at the top cover area of the hood so that the liquid quantity at the top cover area can then be drawn off from the hood. An apparatus especially suitable for this method is characterised by at least one funnel-shaped hood which is open at the bottom and has an inner space tapering conically upwards and an opening in its topmost cover area. A line for drawing off the liquid collected in the topmost cover area can then be attached to the opening.

Title: Band saw for accurate cutting e.g. rubber - runs round two rollers past slotted table where work is fed in to saw while supported by vertical stop roller and side plate
Inventor: ROMINGER HEINZ
IPC: B27B27/02
Filed: 1989-10-27

Title: Solar-heater for water, using roof - has pump controlled by temp. difference and operating at intervals to obtain water by higher temp.
Inventor: MAJEWSKI HERBERT
IPC: F24J2/04
Filed: 1990-02-27
Abstract: The solar heater for water has a pump which operates at appropriate temperatures and at intervals. The pump lifts water to the roof, and the water runs through an isolated, serrated channel. In winter, air escapes through a bypass. The pump operation is controlled by the temperature on the roof.

As the pump operates only at intervals, the device heats up to higher temperatures when cold water is not present, allowing the average temperature of the water from the device to be higher.
Patent DE-4006340-A1 (DE)
IPC: F02B3/06
Filed: 1990-03-01
Abstract: A hydraulically controllable injection timing adjustment device for an injection pump, in particular of a Diesel engine, comprises adjusting and compensating eccentrics (2,3) arranged between driven and driving elements (1,4). Each adjusting eccentric (2) is associated with a setting piston (9), which is loadable against a restoring force, for actuation of the adjusting eccentric. Lubrication of the eccentric adjusting system and ventilation of the hydraulic setting system is achieved through provision of throttle channels (91) in each piston to extend from its end faces to a receiving bore for the associated setting pin (13). The pin itself has an annular and central channel arrangement (131) which corresponds with the throttle channels (91) and opens in a respective receiving bore (21) in each adjusting eccentric (2), into which bore the pin engages with little play by a crowned outline (14). Radial channels (22) extend from each bore (21) to the external circumferences of the respective adjusting and compensating eccentrics (2,3). <IMAGE>

Patent DE-4013837-A1 (DE)
Inventor: BUCHMANN WINFRIED
IPC: B26D5/00
Filed: 1990-04-30
Abstract: In order to improve a process for precisely cutting to size blanks (74) in a web of material (34) having a pattern (88) with a pattern repeat (R), the picture to be cut (72) is subdivided by reference pieces (76-80) spaced apart by predetermined control intervals into intermediate subsections (U1, U2, U3). The exact position of the outer profile of the first reference piece (76) in relation to the pattern repeat is determined. Once the subsection that follows the first reference piece is cut out, the precise position of the outer profile of the following reference piece in relation to the pattern repeat is determined and compared with the position of the first reference piece. The difference between the positions of the outer profiles of the reference pieces in relation to the pattern repeat is determined and transmitted as a correction value (K) to a control device and the following subsection is cut out taking into account the correction value.

Title: Power economy device for piston compressor - involves suction valve with control pressure switchable between work and no-load positions
Inventor: UNGER HANS
IPC: F04B49/02
Filed: 1990-08-23
Abstract: Between the piston compressor suction connection (13) and the suction valve (25) is an automatically functioning two-way valve (31) which with the suction valve in the no-load position it is switchable to a position, by virtue of the build-up pressure in the suction chamber (9), in which it closes the connection between the suction chamber and the suction line connected to the suction connection (13). The two-way valve switches to a position in which the connection between suction chamber and line is freed when the suction valve moves from the no-load to the work positions by reason of the vacuum forming in the suction chamber. USE/ADVANTAGE - To provide power economy in piston compressors, partic those for compressed air prodn in motor vehicles.

Title: Ring spinning frame - has moving sensors at time of automatic doffing to ensure no spindle winds without a tube
Inventor: WIESE FRANZ JOSEF
IPC: D01H13/14
Filed: 1990-11-28
Abstract: Monitoring a doffing procedure on a ring spinning frame during which lifters release the full cops from the spindles is achieved by separate working of a series of sensors moving along the lifting device. Each section of the frame which has an automatic doffing device, and which is active along a certain number of spindles, has three sensors. The sensors are held on a band which traverses between end wheels, so all three sensors pass the row of spindles at the same time of cop changeover. ADVANTAGE - Avoids any one spindle being left without a cop tube and not being sensed, or a spindle being wound without a tube present and attempts being made to fit a tube on this spindle with yarn on it, which would cause a breakdown.
