Title: Continuous pre-tensioning adjustment for double nut - consists of nut and counter nut, and incorporates ball joint drive and threaded spindle
Inventor: SCHNEIDER KLAUS
IPC: F16H25/22
Filed: 1990-12-12
Abstract: The continuous adjustment is for pre-tensioning the double nut of a screw-drive consisting of a nut (11) and counter-nut (12), especially a ball-joint drive (10). The adjustment engges with a continuous row of balls (13, 14) travelling round in their threaded tracks with a continuous threaded spinle (16). Between the two nuts (11, 12) is a tensioning piece (20) adjusted by a tangential control. A lug protrudes axially beyond the but`s (11) end surface, with a side flank. A cavity at the end of the counter-nut (12) has a lug fitting into it. A tangential threaded hole in the counter-nut (12) opens into the recess and contains a screw-adjusted pin supported on the lug`s flank. ADVANTAGE - The adjustment is compact and ecomically produced.

Patent DE-4103777-A1 (DE)
Inventor: MOLDENHAUER HERMANN
IPC: H01F7/18
Filed: 1991-02-08
Abstract: A compression space (4) which is connected to the valve inlet (Z), is arranged on one side of a differential piston (2) supporting the valve plate (2.1), a control space (5) being arranged on its other side. The compression space (4) is connected via the valve seat (3) to the valve outlet (A) and, via a control orifice (10) in the differential piston (2), to the control space (5). The control space (5) is connected to the valve outlet (A) via a relief channel (6.1-6.2-6.3) which is guided through the magnetic valve seat (9). The magnet coil (16), which is surrounded by a magnet yoke (18), contains a guide tube (15) in which a magnet armature (14) is guided such that it can be displaced freely, the magnet armature seal (8) being arranged on the one end of the magnet armature (14), while its other end is opposite a head piece (17). The magnet armature (14), head piece (17) and magnet yoke (18) consist of soft-magnetic material. The opening impulse magnetises the head piece (17), attracts the magnet armature (14) and opens the magnetic valve. When the closing impulse, which counteracts the magnetisation, occurs, the intrinsic weight of the magnet armature (14) causes it to fall and the magnetic valve closes. The valve can be driven with an energy requirement of approximately 10 mWs per operation cycle.

Title: Knitting machine - includes knocking over and laying sinker composed of two separate controlled parts
Inventor: MUELLER GERHARD
IPC: D04B35/06
Filed: 1991-09-21
Abstract: The knocking over and laying sinker in a knitter, between the slide needles in a needle row, is composed of two separate controlled parts. The knocking-over sinker (22) knocks over the stitches, and a laying slide (21) lays the yarn (10) and temporarily covers the yarn zone. At the knocking over sinker, pref. a further tensioning edge is at right angles to the knocking over edge, and the laying slide forms a holding down edge at its under side across the laying edge. A projection can be formed at the knocking over sinker to give the holding down edge. The laying edge of the laying slide runs generally at right angles to the knocking over edge of the knocking over sinker. The laying edge of the laying slide has a projection which, on laying the yarn, prevents it form sliding on the knocking over sinker. ADVANTAGE - The two sections have controlled functions, independently of each other, to allow a variety of knitting actions in a cost effective operation.

Patent DE-4140376-A1 (DE)
IPC: F15B11/12
Filed: 1991-12-07
Abstract: A pneumatically operable lifting cylinder for linearly moving a piston rod (58) along a guide tube (2) has a first piston end section (12) firmly secured to the guide tube (2) and a second piston end section (32) movable against the force of an axial return component (54), to which the piston rod (58) is secured. Between these two sections (12, 32) there are N(N/>=2) lifting chambers (40, 41, 42) to which pressure can be applied from external fluid sources. These are separated from one another with seals by N-1 pistons (20, 31) arranged between the lifting chambers (40, 41, 42). At both end sections (15), each of the N-1 pistons (20, 31) has a hooked end section (18) which engages with the corresponding hooked end section (18) of the adjacent piston (20, 31) or piston section (12, 32) so that each of the N lifting chambers (40, 41, 42) can be individually moved in its travel (50, 51, 52) between two extreme positions. The latter are defined on the one hand by the minimum distance between adjacent pistons (12, 20, 31, 32) predetermined via the axial length of each of the two hook sections (15) and on the other by the maximum distance between adjacent pistons (12, 20, 31, 32) predetermined via the sum of the axial lengths of the two hook sections (15) minus their axial thickness. It is thus possible in a simple manner to obtain eight different settings of the piston rod (58) with three chambers (40, 41, 42) with a geometrically increasing travel (50, 51, 52).
