Title: Power assisted steering for motor vehicles - has pressure pump with control valve servo motor and pressure reservoir
Inventor: JABLONSKY ERICH
IPC: B62D6/02
Filed: 1973-10-17
Abstract: The pressure pump is driven by the vehicle motor and the control valve has a reaction chamber and is operated by the steering wheel. There is a two position switching valve in the lead between pump and the reaction chamber that operates according to vehicle speed. A spring in the valve closes the connection between the pump and reaction chamber when the vehicle is stationary or moving at slow speed, while the reaction chamber is connected to the pressure reservoir via an oil return lead. The switching valve is coupled to a switching device in the vehicle drive by a hydraulic or electrical connection. This ensures that the first valve position is used for first and reverse gear only. Alternatively, the valve can be operated by a tachometer contact and lifting magnet operating at 10-20 km/hour.

Patent DE-2364612-A1 (DE)
Title: Spindle head for thread tapping machine - automatically reverses rotation of tap by conical surfaces at beginning of withdrawal
IPC: B23G1/46
Filed: 1973-12-24
Abstract: The drive shaft is driven by the machine and the output shaft carries the thread tapping tool. The input shaft is secured to the upper inner conical housing. Between this housing and the lower inner conical housing is a thrust bearing with balls held in a cage which is secured by pins to the outer housing. This arrangement causes the lower housing to rotate in the opposite direction to the upper housing. When cutting a thread pressure on the tool causes the central double cone to engage with the upper housing but on withdrawal the spring presses the cone against the lower housing and so reverses the rotation.

Pref., the internal conveyor belt in this region is above the cans, so that the troughs project down onto them. Esp. for removing water contained in the fish cells, before packing in oil.
Patent DE-2419074-A1 (DE)
Title: Mechanical self-acting valve for rinsing bedpans - with cold, then hot water, finally shutting off both supplies separately
Inventor: MONES HARRI
IPC: A61G9/02
Filed: 1974-04-20
Abstract: The device contains one cold-water valve and two hot-water valves which act alternately. Depression of a piston empties a water-chamber through a non-return valve. Water leaking back into the chamber through a nozzle, fed from hot water inlet returns the piston to its start, at which point the cycle of operation is complete. Meanwhile, the downward movement of the piston has substituted one hot water valve for the other, leaving the hot water still cut off, and opened the cold water valve. This starts the cold water flow which continues until leakage through a small hole into the back of the cold water valve equalises the pressure and a spring returns the valve to its seating. During this time the piston, moving up, substitutes the other hot water valve for the first one, reversing its previous action, slowly, so that hot water, flows first mixed with cold.
Patent DE-2419451-A1 (DE)
Title: Machine tool optical feeler unit - uses surface edge contour projected onto photo elements to provide positioning motor signals
Inventor: SCHNEIDER KLAUS
IPC: B23Q35/128
Filed: 1974-04-23
Abstract: The optical feeler unit is for following drawn curves for machine tools and automatic welding plants. By evaluation of the surface edge projected on to photo elements control signals are supplied to positioning motors such that the corresponding movement takes place tangentially to the evaluated surface edge. The photo currents corresponding to the projection of the surface edge on to photo elements are altered in such a way, via an analogue and digital network, and dependent upon the direction of the tangents to the selected surface edges, that the control signals for the positioning motors are likewise adjusted. One motor has a fixed adjustable speed, independent of the momentary tangent direction, and the other motor is sensitive to the dark-light process.
Patent DE-2427061-A1 (DE)
Title: Puppet head with movable eye balls and lips - marionette is operated by shaft and finger controlled wires
