A third contact reed is fitted to the switch, connected to a dropping resistance. The switch is arranged to close and start the motor, and on further movement of the keeper it opens the connection to the third reed. This open circuits the shunt line across the series resistance and reduces the solenoid current to a holding value. A claw at the end of the keeper acts as a locating brake for the motor, and holds the shutter in the closed position with the motor switched off.
Patent DE-2338449-A1 (DE)
Title: Fault monitoring system for press drive - out of phase synchro resolvers between drive and control drum
Inventor: SCHNEIDER FRANZ
IPC: B30B15/28
Filed: 1973-07-28
Abstract: One of the two synchro resolvers used in the fault monitoring circuit for the stress acts as a transducer. The connection from the mains to the stator of the transducer has an interrupter switch connected with the actuating switch which releases the stroke of the press so that when the actuating switch is closed then the interrupter switch is opened. The drive system switch of the press control system acts in conjunction with the closing of the interrupter switch. This arrangement checks automatically the operational reliability of the drive interrupter before each stroke of the press. This ensures that the press cannot continue working in case of a fault if the drive circuit relay has burnt out.

Patent DE-2349387-A1 (DE)
Title: Change speed gear-box for vehicles - with vibration damping arrangement for greater inter-gear movement for decreasing noise
Inventor: BLUMENSTEIN FRITZ
IPC: F16H57/00
Filed: 1973-10-02
Abstract: In a vehicle gear box noise is caused by speed oscillations from engine or road wheels which in turn cause speed oscillations between the gears within the box. Within the gear train one gear wheel is normally fixed to its shaft; according to the invention, by allowing these gears a small amount of controlled rotational play, the noise can be decreased. The driven shaft carries on splines a fixed gear. A small amount of clearance is given on the flanks of the spline so that the gear wheel may turn slightly, in either direction, relative to the shaft. A groove is cut diametrally on the face of the gear and a spring pin lies within this groove and is held firmly in a hole through the shaft. Each end of the pin is tapered between its head and the shaft. By this means the extent of rotary motion, relative to the shaft is controlled.
Patent DE-2352810-A1 (DE)
Title: Torque limited expander bolt for wall or floor fixing - has capped nut for tightening that is stripped at predetermined torque
Inventor: FISCHER ARTUR
IPC: F16B13/06
Filed: 1973-10-20
Abstract: A fixing bolt for the construction industry utilises the expanding sleeve principle. In this instance the expansion element consists of a closed coiled spring that is caused to increase in diameter by forcing over a tapered plastic sleeve. The sleeve is threaded onto a central pin, the other end of which is also threaded to take a capped nut for tightening purposes. When the nut is threaded onto the pin tightening commences when the pin end bottoms on the top surface of the cap. As tightening continues the expanding element grips the side of the bore. To ensure that the bolt is adequately secured, the nut is rotated until the end section shears. Further rotation of the nut produces no effect.

Patent DE-2364855-A1 (DE)
Title: Shock absorber for motor vehicles - has working cylinder with two oil filled chambers controlled by two spring loaded valves
Inventor: WEISSER ULFRIED
IPC: F16F9/06
Filed: 1973-12-28
Abstract: The particular feature of the design is that the cross section of the valve controlled openings can be altered. The piston and piston rod have piston plates with coincident openings. The plates can be rotated. Turning one plate relative to the other alters the cross sectional area of the orifices. This is done by a rod keyed onto the piston rod that fits in a slot cut near the top suspension point of the shock absorber. The plate can be controlled remotely by means of a cable running from the vehicle instrument panel. The driver can therefore vary the ride to suit conditions.

Title: Marking faults on rods - rods pass e.g. straightener to be used for machining
Inventor: KATZWINKEL LOTHAR
IPC: B21C51/00
Filed: 1974-02-07
Abstract: When rods are rolled from ingots which include faults, the faults sometimes are visible on the surface of the rod. These faults should be detected at an early stage, e.g. when it passes through a straightening or other machine, before it is dispatched to the customer. The fault in the surface of the material is detected by a photocell arrangement which via a control system operates a knurling tool and pushes it against the rod. The knurling tool is mounted immediately behind the straightening rollers. As the rod moves linearly and rotates, a sinusoidal mark is made over the fault which is easily visible when the rod rolls down the outlet chute, as the mark appears to move along the rod while it rolls.
