Patent DE-4134630-A1 (DE)
Title: Reciprocating piston engine with adjustable stroke - has adjusting spindle in crank shaft, to adjust intermediate bearing shell for connecting rod bearing
Inventor: JAEHN EGON
IPC: F02B75/04
Filed: 1991-10-19
Abstract: The engine has an adjusting spindle, located centrally in the crank shaft. The spindle adjusts an eccentric intermediate bearing shell for the connecting rod bearing.

Title: Textile card installation with draw frame - has buffer movement to accumulate sliver to balance production between the machines
Inventor: STAHLECKER FRITZ
IPC: D01G15/64
Filed: 1992-04-16
Abstract: An installation of carding machines with at least one drawframe, has a sliver transport system, which acts as an accumulator, controlled by the working speed of the card. The sliver is deposited from several cards on to a conveyor band, which is running slower than prodn. from the cards. A series of textile carding machines produces sliver which is laided by a mechanism in a meandering loop or spiral manner on to a conveyor band. From this band, the sliver rises to the doubling table of the drawframe by means of suitable guides. Five slivers are utilised by the drawframe and the drawframe takes a further five, further along the installation. A distance of approximately 80 cm is allowed between the cards and this gives sufficient tolerance for the loop accumulation. ADVANTAGE - The sliver from a carding set is delivered directly into a drawframe, with a buffer movement between, which allows one or the other machine to stop, without affecting quality.

Title: Servo-valves for the control of volume flows
Inventor: WACHOWIAK JERZY DIPL ING
IPC: G05D7/06
Filed: 1993-06-14
Abstract: Servo-valves of known type for the control of volume flows require expensive precision machining of their individual parts during manufacture and, during their use, can be driven by electronic control devices, for example memory-programmable control devices, only via expensive converters. The new servo-valve consists of individual elements, such as for example conventional 2/2-way valves, which are simple to produce and can be driven by an electronic control unit via simple electromagnets. The servo-valve consists of a parallel arrangement of individual valve elements which can assume the two operational states "open" and "closed" and whose effective flow rates in the opened state are stepped in the same ratio as the digit values of binary numbers. By means of actuating the individual elements in accordance with the sequence of binary numbers, the operating state "open" of the elements corresponding to the binary number 1 and the operating state "closed" of the elements corresponding to the binary number 0, various volume flows can be set. Fields of application are hydraulics and pneumatics. <IMAGE>
