Title: Device for measuring shape and angle
Inventor: DEPPERT EDGAR
IPC: G01B5/24
Filed: 1988-02-12
Abstract: In a device for measuring the shape and angle of tracks (raceways) 1 or the like of large antifriction (rolling-contact) bearings, the runner ring 2 rests with its lateral surface on an inclined supporting plate 3. A measuring device 10 is provided with a linear guide 13 which has a probe 16 for displacement along a generatrix 17 of the track 1. In order to bring the linear guide 13 into a vertical position which delivers the most accurate measurement results, it is firstly inclined with respect to the supporting plate 3 in such a way that it extends in the direction of the generatrix 17 of the track 1. Furthermore, the supporting plate 3 is inclined by the angle  alpha of the track 1. <IMAGE>

Filed: 1988-04-26
Abstract: In this method or device for separating cards, such as cheque cards or identity cards, the card to be separated is in each case first moved into a separating groove, as a result of which it passes out of the region of a stop holding the stack. The card which is pre-separated in this way is subsequently completely lifted off the stack by means of a suitable removal device. In this way, cards can be separated in a very reliable and gentle manner.

Title: Headset for telephone systems
Inventor: CHILLA JUN CHRISTOPH
IPC: H04M1/05
Filed: 1988-09-13
Abstract: Telephony with usual telephone sets is very difficult or associated with great effort in a noisy environment.

Patent DE-3902559-A1 (DE)
Title: Quick-change chuck
Inventor: HOEFLE LOTHAR
IPC: B23Q1/00
Filed: 1989-01-28
Abstract: A quick-change chuck for taps has a receptacle with a head and in the head a housing on which a pin sits which is guided in a coaxial bore of the receptacle. Sitting between receptacle and housing is a tension/compression length-compensating device with springs. The pin contains an inner passage which is connected to a feed passage for feeding pressurised coolant and extends up to the housing so that the coolant can flow up to an insertable quick-change insert and tap. Seated between the receptacle and the pin is a guide sleeve. The pin and the guide sleeve are dimensioned and sealed off in such a way that they are in equilibrium despite the coolant pressure which prevails in the interior and acts on their axial surfaces. Even high coolant pressures result in no additional axial forces on the housing with pin and guide sleeve. Easy-action length compensation is guaranteed. The chuck is simple, compact, light and inexpensive.

Title: Separating top film of stack - involves vertical pin with radial hole for spring loaded ball
Inventor: DOLL FRIEDBERT
IPC: G03B27/02
Filed: 1989-06-19
Abstract: The copying machine has a table (1) which supports a stack of films (10). The films are removed from the stack by a suction device which removes the top film (9) and delivers it to the copying machine. The lower films are prevented from sticking to the top film by means of a vertical pin fixed to the table (1). This pin has a radial hole (5) in which a spring (6) loaded ball (7) is fitted.  The ball is held captive in the hole by peening over the edge of the hole so that part of the ball projects beyond the pin surface. The spring (6) forces the ball between the top film (9) and the film lying immediately below so that only the top film is removed by the suction device. USE - Copying machines paper sheet or plastics films handling system.

Title: Compensated steering for motorcycle - has eccentric mounting for front forks to counteract off-centre tyre grip when cornering
Inventor: WEIDELE ALOIS DIPL ING
IPC: B62K21/00
Filed: 1989-10-04
Abstract: The steering axis (7) of the front forks is supported by a bearing race (14) located between eccentric outer (15) and inner (16) shells. The relative positions of the eccentric shells are controlled by servo drives (17,18) to move the steering axis to either side of a middle position. This is to couteract the force generated by the off centre grip of the tyre when leaning into the curve. The servo drives are regulated by a tilt sensor (20), and alter the steering axis setting just sufficiently to balance the moment generated by the tyre grip point w.r.t. the centre plane through the tyre. ADVANTAGE - Balanced cornering control, less accident risk.
