Title: Speech audiometer coupled with tape recorder - displays associated group of similar sounding words with each word from tape recording
Inventor: GAHLEITNER ERWIN
IPC: A61B5/12
Filed: 1973-10-03
Abstract: Speech audiometer has test words presented to the subject in succession from a tape recording, and contains a comparator which compares the word presented with the word as heard by the subject, and only emits a given signal when these coincide. Pref. the comparator contains an indicator for the presented word and group of words containing at least one sounding like the one presented. The reproducer is coupled to the comparator so that the indicator automatically displays the correct associated work group. A specially constructed tester is not necessary. Pref. the control signals for the test specimens are of a non-audible frequency.

Title: Pebble-bed reactor with graphite side reflector - having indented inner face to prevent retarding of fuel descent
Inventor: SCHWIERS HANS-GEORG
IPC: G21C11/06
Filed: 1973-10-31
Abstract: A side reflector for a nuclear reactor is situated between the core and the thermal shield and constituted of stacks of prismatic graphite blocks, defining a cylindrical chamber to contain the spherical fuel elements. A large number of the graphite blocks have, on their reactor-facing side, a depression, extending in the direction of flow of the fuel elements at least for two element dias. and transversely to that direction by at least one element dia; the depth of each depression is 1/4-1/2 (1/3) of an element dia. Pref., these depressions each extend both tangentially and axially; they may be elongated having their longitudinal axis parallel to the longitudinal axis of the cylindrical core space; or they may be circular. Appts. is used esp. in a pebble-bed reactor, where the braking effect of the side reflector tends to retard the downward travel of the fuel elements in the peripheral zone. By interrupting the surface of the reflector by a series of the depressions described, this retarding effect is largely neutralised so that all elements travel downwards at the same speed.

Title: Motor vehicle IC engine propellant - liquid methanol is transformed to a vapour in exhaust heated reaction carburettor
Inventor: HEITLAND HERBERT PROF DR ING
IPC: F02D19/08
Filed: 1974-10-23
Abstract: The conventional internal combustion engine is propelled by a simultaneous supply of air, liquid methanol (CH3CH) and a vapourised fuel mixture consisting of hydrogen and carbon monoxide.

Inventor: SEIFRIED ALBERT ING GRAD
IPC: G01R17/02
Filed: 1975-09-04
Abstract: The test valve pick-up is balanced w.r.t. magnitude and phase. An in-phase rectifier for the modulated test signal is supplied with the same carrier voltage.

Title: Speed independent instantaneous direction indicator - uses memory flip flop, reset flip flop and two NAND gates
Inventor: CAP HEINRICH
IPC: G01P13/04
Filed: 1975-10-25
Abstract: The instantaneous direction indicator detects direction of motion without delay and independently of speed. The clock inputs of a memory flip flop each have a 2-input NAND-gate connected to it. The inputs of the NAND-gates receive signals denoting a change in state (direction), the one input signal to each gate being direct and the other input delayed. The gates comprising the memory flip flop each have a further input to block the outputs connected to a reset flip flop. The reset flip flop is set by an input (eg supply'on'). The outputs of the whole circuit can therefore be forced to block at H.

Title: Lubrication of plastics in relative movement - using PTFE in powder, flake or paste form
Inventor: GERFERTZ BRUNO
IPC: F16C1/24
Filed: 1975-10-30
Abstract: PTFE is a lubricant between plastics surfaces in relative movement, esp. between acetal resin moving in contact with polyamide resin. It is used in Bowden or similar cables, in which a plastics coated core, e.g., of wire strands, moves inside a plastics outer sheath. ]Friction is greatly reduced, which lessens the operating force required and prevents stick-slip movement. Efficiency of the lubricant improves with use. It is resistant to heat and cold and has no adverse effect on the plastics materials.
