Patent DE-3924909-A1 (DE)
Inventor: TROTT JOSEF DR
IPC: H01H9/56
Filed: 1989-07-27
Abstract: In a process for operating a triple-pole power switch, the switching operation is initated by a trip control device for the switching section of a phase at a time such that the current is automatically interrupted in the corresponding phase during the next zero passage. The other two switching sections are also actuated either simultaneously or out of phase within a predetermined opening window so that the current in these phases is also interrupted in a surge-free manner. Depending on the configuration of the network and on whether the opening of the two remaining switching sections is effected simultaneously or out of phase, the phase shift is equal to one-third, two-thirds or one and a half half-waves. The switching process is particularly suitable for vacuum power switches in inductive electric circuits.

Title: Spindle journal bearing - has CAMs to give point support to roller ends and present spindle upper part from rising
Inventor: STAHLECKER GERD
IPC: D01H7/04
Filed: 1989-09-29
Abstract: The bearing for a spinning or twisting spindle, partic. a journal bearing, has cams in an axial direction in the pockets for the rollers. The cams provide a general joint support for the rollers at least close to the longitudinal axis of the rollers, and the end sides of the rollers towards the cam are grooved. The axial length of the pockets is greater than the axial length of the rollers by at least 2 mm. Any axial movement of the roller cage can be restricted by an upper safety lock, at a gap from the top of the roller cage which is less than the difference between the axial lengths of the roller pocket and the rollers. The safety lock is a disc inserted into the spindle bearing housing to pass over the roller cage. ADVANTAGE - The bearing structure prevents the upper section of the spindle from rising.

Title: Fuel injection pump for IC engine - prevents fuel surges keeping engine running when stopping by selecting pressure-relief channel at given pump piston travel
Inventor: RUESSELER KARL-FRIEDRICH ING G
IPC: F02M41/12
Filed: 1989-12-29

IPC: D03C3/20
Filed: 1991-05-17
Abstract: A shedding device for a textile machine contains two lifting blades (120) which move to and fro antagonistically, two traction elements (121) which can be engaged and disengaged with the lifting blades (120) and an insertion device (12) which is arranged so that the traction elements adopt a defined position with respect to the pole regions when in the lower shed position.
