Title: Contactless test values transmission - designed for detection of electrical and non-electrical quantities
Inventor: UMMEN FRANZ
IPC: G01K13/04
Filed: 1974-05-13
Abstract: The device is intended for transmission of physical quantities in measurement, control and/or monitoring equipment. It comprises a constant or pulsating light source with a parallel light beam directed to a reflector, so that it can scan any number of photocells arranged next to each other. The photocell on which the beam falls depends on the reflector deflection, and thus on the respective physical quantity. Voltage or voltage change generated in the scanned photocell is applied directly or through an amplifier to a test value generator which delivers it in the analogue or digital form, depending on the generator design.

Title: Number selective device for lotto game - uses numbered counters shaken through holes of circular box
Inventor: EBERT CURT ADOLF
IPC: A63F3/06
Filed: 1974-07-09

Title: Sprung tandem stub axles - with joining leaf spring semi floating in hollow supports each side of central mounting point
IPC: B60G5/047
Filed: 1975-03-14
Abstract: The axle stubs of the twin axle unit are fitted to the ends of square cross section metal tubes with the two tubes joined by an elastic section positioned at the mounting points on the chassis. The square section tubes can thus perform suspension movements relative to each other.

Title: Servo assisted brake pedal for motor vehicle - has electric motor driven flywheel and pedal operated friction drive
Inventor: KIRSCHNER PETER DIPL ING
IPC: G05G19/00
Filed: 1975-06-20
Abstract: The brake pedal servo mechanism offers the advantage of small size and works independently of type of vehicle engine compared with conventional vacuum-assisted devices. The pedal linkage which operates the master cylinder of the brake hydraulic system (1) has a drum (2) and an outer casing (8) driven from an electric motor. Both are centred on the pedal shaft (9). Between the inner drum and the outer rotating part is a spring-loaded friction assembly (7). The motor-driven flywheel rotates freely in the direction of the operated pedal movement. Operation of the pedal causes the friction springs to expand thus transferring drive from the rotating part through the drum to the operating linkage. This power assistance greatly reduces the pedal effort required to operate the brakes.

Title: Printing machine for magnetically recording on tickets - has magnetic reading and recording heads movable with printing inking pad
Inventor: NOZAKI TATSUZO
IPC: G06K1/12
Filed: 1975-12-20
Abstract: The printing machine for partially magnetized price tickets, labels etc. incorporates a single magnetic head or a pair of heads for recording and reading of the magnetized faces of tickets. The magnetic head or heads can be movable horizontally and also be located right under a horizontally movable inking pad of the printing device to go back and forth together with it. The printing machine can be constructed in a size almost the same as that of a conventional ticket printing machine. The printing machine avoids the problems arising because the printing happens to be different from the recording and also assures the prevention of misrecording.
