Title: Profiled cylinder lock with pins and springs - releases keys on inner and outer side on completion of locking
Inventor: SCHMELZER JUERGEN
IPC: E05B27/00
Filed: 1975-04-09
Abstract: The profiled inner cylinder of a lock is made in one piece and the two bores in the internal cylinder are made slightly oversize. The key on the inner side is pushed by spring force out of the locking position after the completion of the locking operation and after the locking key is removed. The locking key is pushed out of the locking position by th elocking pins and the opposite push of the inner key after completion of locking. The locking key has mirror image teeth on both edges and can hence be used for the inner and outer side of the profile cylinder. The outer cylinder has an eleventh locking pin adjacent to the tenth pin so that the elevement pin prevents locking from outside when the inner key is in position.

Title: Automatic exposure control circuit - has photo transistor with integration capacitor feeding threshold detector connected to lamp and shutter cut off
Inventor: KRAUSE GERHARD
IPC: G03B7/083
Filed: 1975-11-28
Abstract: The light from the subject to be photographed is received by the collector base section of the phototransistor (T1). An integration capacitor (C) is linked in series to the collector base of the phototransistor (T1) so that current flowing across it (T1) can be integrated. The resultant voltage fluctuation controls the base emitter sector.

Title: Thrust bearing with spherical shaft end - has thin walled socket resilient backed by soft solder to dissipate friction heat
Inventor: KETTENHOFEN DIETER
IPC: F16C33/10
Filed: 1976-08-28
Abstract: The thrust bearing comprises a spherical shaft end (2) having spiral grooves and engaging a thin-walled socket (4). The periphery of the socket is reversed (5) to define an edge (6) facing in the direction of thrust. This edge rests on an annular abutment (7) at the inside of a housing. At the outside of the socket the housing is filled with a soft solder (11). Resilience of the thin wall of the socket enables a uniform distribution of lubricant present in the bearing.

Title: Leaf spring valve for air compressor - receives progressive support from valve plates during deflection
Inventor: HARE JOHN
IPC: F04B39/10
Filed: 1976-09-22
Abstract: A compressor cylinder (13) has its inlet and outlet valve formed by a leaf spring (16). The valve spring (16) which is basically circular, has a set of tongues which are deflected according to the air flow. Two valve plates (15) clamp the valve spring so that air can flow in a and out of the compressor cylinder (13). The valve plates are shaped so that the valve spring tongues are progressively supported as they are being deflected. This support of the valve spring ensures that uniform stress distribution occurs, thus the working life of the valve spring is increased.

Title: Stereo headset with simplified mounting - has asymmetric universal suspension with single arm to permit simple adjustment
Inventor: BEBENROTH WOLF-DIETRICH
IPC: H04R1/10
Filed: 1976-09-23
Abstract: The easily-adjusted headphone assembly consists of a sprung headband (1) at each end of which is suspended an ear-piece capsule (2). Instead of the usual stirrup-shaped fork suspension, the capsule is attached by one pivot only (5) to the lower end of a curved strip (3). The strip is attached at its upper end to a vertical pivot pin (4) which rotates in a bush in the end of the head band. The capsule is thus free to move about its vertical and horizontal axes. With this type of construction, the suspension axes are unsymmetrical and this makes handling and adjustment by the user much easier. In the case of stereo headphones, with the single suspension arm being positioned behind each ear, the correct left and right channel capsules are in contact with the respective side of the head. For forward-facing edge of the capsule (B) may be fitted with a pick-up device (11) to enable the headset to be used without leads.

IPC: A63J1/02
Filed: 1976-10-29
Abstract: The incremental winch is for use in vertical movement of theatre stage props, and has an electromotor-driven drum for each winch location. A control method is employed which enables the drum motor units to be mounted directly on the support over which the cords pass and to run synchronously. The movement or position o each cord is measured, converted into an electrical signal, and compared with a reference value. The difference between each position signal and the reference is amplified and used to control the corresp. motor. The position measurement is performed by a potentiometer.
