Title: Fail=safe gate for utility vehicle gearbox - has logical path through intermediate gears by raising and lowering lever
Inventor: KONRAD ALFRED DIPL ING
IPC: F16H59/04
Filed: 1978-05-12
Abstract: The failsafe gate for the gearbox of the utility vehicle has the intermediate gears set in the gate in such a pattern that the driver has to operate the gearchange lever through the logical sequence of gears and intermediate gears. The intermediate gears are obtained by depressing or raising the gearshift lever alternately.

Patent DE-2911471-A1 (DE)
Inventor: SCHONHARDT PETER
IPC: H01H43/06
Filed: 1979-03-23
Abstract: A switching device consists of an elongate member such as a chain or belt including a plurality of elements 1 at least one of which can be moved laterally of the longitudinal axis of the member. The member is preferably flexible and endless and the lateral movement is, in one embodiment, achieved by the provision of tenons 3 and grooves 4 formed integrally with elements 1 and linking them together as a chain. When displaced laterally, an element 1 engages a switching member 5 when the elongate member is driven past the switching member 5 by e.g. rotation of a pinion 2. The device is suitable for use in a time switch when elements 1 act as trips to set a switching programme. Instead of each element 1 being displaceable laterally as a whole, it is possible for only a portion of each element 1 to be so displaceable. <IMAGE>

Title: Direction dependent coupling for magnetic tape drive - has pulley with pivoted drive dog responsive to direction of shaft rotation
Inventor: INDERST JOSEF A ING GRAD
IPC: G11B15/50
Filed: 1979-06-13
Abstract: The coupling for use in tape capstan drives within magnetic tape recorders engages for one direction of motor shaft rotation and disengages in the other direction. Tape motion is provided by a didirectional motor with a belt drive to one of two pulley wheels (6) mounted on the capstan shaft (2). Transmission to a capstan (10) is dependent upon the directional coupling provided by a pivoted dog (7b) that moves within a quadrant slot within the pulley wheel. When the motor rotates in one direction the dog locates against a pad (14) on the capstan to transmit motion. When the motor direction reverses the pulley is slowed down by a gear driven (3) disc spring (4) loaded against the base and the dog moves in the quadrant to disengage.

Title: Electronic heat detector circuit for flat radiators - uses Wheatstone bridge with one branch formed by radiator heat sensor, while another branch contains room temp. sensor
Inventor: HENNEBERGER HEINZ
IPC: G01K17/06
Filed: 1979-06-22
Abstract: The circuit is intended for detaching heat emitted by flat radiators during a selectable time period. The radiators carry temperature sensors, firmly screwed at a specified height and connected in series. This series connection form a branch of Wheatstone bridge, whose other branch is formed by a room temperature sensor. The bridge supply voltage is provided by a pulse generator at discrete, equidistant time points only. The generator triggers a scanning and hold circuit, which supplies the bridge diagonal voltage during the time period between two voltage pulses. The output voltage of this circuit is converted into a pulse train by a voltage-frequency converter, the pulse train frequency being proportional to the voltage. The pulses are integrated by a counter. Pref. the series-connected temperature sensors are NTC resistors with practically linear temperature dependence.

IPC: A23G1/04
Filed: 1979-09-10
Abstract: A granular crystallisable paste is converted to a product with a fine and homogeneous size consisting, specially of cocoa paste to chocolate paste, by roasting in a thin layer. This is applied by a spreader roll to an internally heated roll with a shell rotating around a stationary core. The core includes hydraulic plungers which are applied to the shell and compensate for any deflection. Process does not require highly skilled personnel. The equipment is less costly and takes up less floor space. The thin film results in short diffusion and thermal paths.
