Patent DE-2331046-A1 (DE)
Title: Electric typewriter corrector mechanism - with drive shaft released by actuating pawls during overload
Inventor: JOHANNSEN FRED
IPC: B41J7/30
Filed: 1973-06-19
Abstract: The mechanism operates when more than one key is depressed in quick succession with control by stop attached to the typewriter frame. The drive shaft is normally pressed against the stop by a preset spring force, and, in case of overload due to simultaneous release of drive pawls, it is lifted out. This brings back the pawls to their original position as a result of tension due to a spring. A bearing plate holding the drive is operated by an elastic belt, tensioned by a lever loaded by a spring.

The dyed goods are then dried and the dyes heat-fixed. Yellowing of the textile material is obviated. Polyester/cotton textiles can be dyed with bicoloured effects which are both very bright and fast.
Patent DE-2342767-A1 (DE)
Title: Magnetic seating with permanent magnets and electromagnets - has permanent magnets for static load part and electromagnets for controlled positioning
Inventor: LYMAN JOSEPH
IPC: F16C39/06
Filed: 1973-08-24
Abstract: Prior designs endeavoured to use for positioning and seating of elements in motion either permanent or electromagnets. In both cases the required outputs and consequently the resulting physical sizes were too large. The present arrangement is fitted with an auxiliary magnetic field operating in the way of a controlled servo system. The electromagnets emit controlled forces in the direction of the body in motion when it moves out from a neutral position. The deviation of the body from the basic position can be picked up by a photoelectric system emitting a control signal to rectify the deviation.
