Patent DE-4201575-A1 (DE)
Title: Spinning frame - has pneumatic clutch at sliver delivery and drafting zone to stop prodn. in the event of a yarn break
Inventor: STAHLECKER FRITZ
IPC: D01H5/00
Filed: 1992-01-22
Abstract: A spinning frame has a series of spinning positions with drafting rollers. There is also provision for sliver delivery from a card can at each position. Both of the drafting rollers and sliver delivery have means to stop prodn. in the event of a yarn break. The yarn sensor controls the operation. Pref. the spinning frame has a series of spinning positions with drafting rollers to acccept the silver. This is positioned near each spinning unit in a card can, and is guided from the can to the input funnel, by an endless band which is driven by the roller. The centre is driven from a drive shaft in the same manner as the centre (34) for the bottom input roller of the drafting zone. Both these rollers have a clutch engagement with a tubular outer circumference which can be disengaged by means of air pressure, which is supplied along the tubes from the controlled source. The control is in turn actuated by the yarn sensor, which may be placed to sense the presence of the yarn. Alternatively, the sensor may be fixed in the service robot which runs along the series of spinning positions. ADVANTAGE - The frame can be run automatically. The sliver is prevented from accummulating around rollers, which would case damage. On recommencement of operation, when the break has been pieced, there is immediate availability of fibre to continue spinning.

The dia. of each disc spring is such that when compressed flat the OD is smaller than the dia. of the hole (4) in the ball (1). The neck has a self lubricating cover (10) along its length. USE/ADVANTAGE - The disc springs in the hip joint prosthesis are less susceptible to fatigue failure than the helical coil springs which are usually fitted.
Patent DE-4206665-A1 (DE)
Title: Method of increasing thrust of jet engine - involves injecting water into combustion gases before they flow into jet nozzle
Inventor: RATHSBURG EDGAR
IPC: F02C3/30
Filed: 1992-03-03
Abstract: Water is injected into the combustion gases before they flow into the net nozzle. The water is evaporated to form steam and at the same time cools the combustion gases. The steam increases the volume and also the mass flow through the jet nozzle and so increases the reaction force generated by the jet and at the same time reduces fuel consumption. The water required for the process can be carried in the space made available by the reduction in size of the fuel tanks. ADVANTAGE - The reduced temperature of the jet efflux also reduces the pollution caused by the exhaust gases.

The distance between the axes can be varied.  The angles are measured by passive or active transducers arranged on or coaxial to the axes. USE/ADVANTAGE - E.g. for use in machine construction or arms mfr.. High precision measurement of angle between two measurement arms is achieved without axes having to be at partic. defined distance apart.
