Inventor: VOOS UDO
IPC: F02G1/04
Filed: 1977-03-31
Abstract: The Stirling engine has one or more displacement pistons (17) and working pistons (3).

Title: Pipe flange connection for ship or chemical industry - uses welded rings and loose flanges clamped together by bolts through holes outside ring circumference
Inventor: EKBERG SVEN ERIC
IPC: F16L23/032
Filed: 1977-05-12
Abstract: The flange connection between lengths of pipe has welded rings and loose flanges, of which one is loosened on one of the pipe ends behind the corresponding welded ring. These are arranged to be clamped together by bolts extending through holes outside the circumference of the welded rings. The welded rings have on their rear side two ring-shaped contact surfaces separated from each other by a relatively deep and wide ring-shaped groove, or by a number of relatively deep but narrow ring-shaped concentric grooves. The outer contact surface is deeper than the innter contact surface. When the loose flanges are conically bent over the welded rings a compensated pressure distribution of the loose flanges occurs on the contact surfaces. This provides sealing between the welded rings.

IPC: B65H35/00
Filed: 1977-06-24
Abstract: Dimensionally accurate plastic films, woven and other fabrics and thick sheets of paper are often required in the building trade. A device having an unrolling support (AT), a base (AL), a holding-down device (NH) and a cutting tool, which is guided between two guiding edges (TFK) which are situated one behind the other, is provided for the clean cutting to length, at right angles, of flat web-like material.

Title: Dish washer operation accelerating soln. of cleaning agents - permits usage of cheaper salts normally dissolving more slowly
Inventor: HARTENSTEIN HELMUT
IPC: A47L15/00
Filed: 1977-12-24
Abstract: The cleaning agent stock tank of a dish washing machine is modified so that the washing agent contg active chlorine and polyphosphates is dissolved more easily. A sieve is fitted, the mesh of which is so small that the washing agent in the solid state cannot pass through, and the water level is maintained above that of the chemical mixt. Beneath the sieve an inclined plate with passages at the top and bottom edges stimulates circulation of the water, and the soln. of the chemical agent for dosage into the washing water. Caking of the chemicals at the bottom of the stock tank is not only prevented, but the improved speed of soln. makes it possible to use cheaper sodium instead of potassium salts.

Title: Volatile RAM content protection during mains failure - using timed reconnection stage to ensure that transient surges are inhibited
Inventor: GRAEF ROLF DIPL ING
IPC: G06F1/24
Filed: 1978-01-25
Abstract: A standby system to ensure that the contents of a volatile random access memory (RAM) are protected during a mains power supply failure, includes a facility for protection against disturbance pulses. A comparator generates an output if the supply falls below a specified level. A decouplic stage inhibits the RAM write input and an alternate supply maintains the contents. When power returns a timing stage only outputs once it is certain that it is not merely a transient surge. A switching stage removes the inhibitor to the write input and a start pulse is generated.

Title: Single-phase AC motor reversal unit - has control relay connected between electronic time switch and motor windings
Inventor: SCHEER ERICH ING GRAD
IPC: H02P23/24
Filed: 1978-03-21
Abstract: Angle-phase AC motor reversal unit is partic. for use with automatically controlled washing machines. Safe and reliable reversal is achieved by using an electronic time switch with a control relay connected between it and the motor windings (W1, W2, W3) of the single-phase motor (WM). The motor windins are alternatley switched on the voltage terminals via a contact actuated by the time switch which is used, according to the direction of rotation of the motor, to deliver a signal directly to the winding system of the control relay. As a result, the reversal contact of the control relay takes up a position for taking current to the corresp. winding of the single-phase motor (WM).
