Title: Railway brake adjusting device - has compression spring keeping locking ribs in grooves
Inventor: KAPFENBERGER DIETER
IPC: B61H5/00
Filed: 1975-06-26
Abstract: A disc brake for railway rolling stock, has levers (1, 1a) pivoted on supports (2, 2a) connected by the fitting (12) and adjusting bolt (6). To compensate for brake pad wear the supports (2, 2a) must be screwed closer together by rotating the bolt (6). The head (16) of the adjusting bolt (6) has two diametrically opposite radial ribs (18). These ribs (18) fit in matching grooves (20) in the end face of the support (2a). The force of the compression spring (10) which fits around the bolt (6) keeps the ribs (18) in the grooves (20) and prevents any unwanted rotation of the bolt (6) but allows the bolt to be adjusted when required in steps of 180 deg. of rotation.

Title: Servo assisted steering for battery vehicle - with simple lock sensor operating above set lock to monitor degree of movement
Inventor: LISTING VOLKMAR
IPC: B62D5/00
Filed: 1975-10-16
Abstract: The steering column fo the battery driven vehicle is fitted with a lock sensor bolted to the column outer and monitoring the amount of steering wheel movement using friction drive wheel and a tachogenerator. The amount of servo force is controlled by the steering lock. The tachogenerator only provides an output signal when the steering wheel is moved, and switches off the servo when the wheel is steady and when it is straight ahead. This saves considerably on power drain and enables the servo to be used on battery vehicles. It can be retrofitted to existing vehicles. A spring holds the friction wheel against the steering wheel.

Title: Determination of hollow waveguide reflection factors - of reflecting points located by pulsed echo method using reference reflector
Inventor: TRAEGER ALFRED DIPL ING
IPC: G01R31/11
Filed: 1975-10-23
Abstract: A method of determining the reflection factors of a hollow waveguide's reflecting points located by the pulsed echo method is used both during construction and operation of the waveguide to obtain quantitative measurements of the cause of disturbances and their effects. A reference reflecting point of known reflection factor is arranged in the waveguide. The echos reflected from the reference reflector and the inherent reflecting point are compared in amptitude with allowance for the damping difference due to the transit time from each point. The unknown reflection factor is then determined by a substitution method.

Title: Electronic control for marine engines - has alternate cylinders disconnected under low power of idle conditions with secondary shaft for balancing
Inventor: TRENN THADDEUS JOSEPH DR PHIL
IPC: F02D17/02
Filed: 1976-11-22
Abstract: The ic engine is operated by disconnecting working cylinder alternately. The engine can be reciprocating or totating pistons and may be used in marine propulsion engines when they run an idling speeds. The cyclic disconnection of cylinders ensures that smaller gear drives can be used, because the engine itself widens the partial load running range. The cyclic disconnection system can be used for four or two strokes engines, with the cylinders electronically connected and disconnected. Compensation of inertia is ensured by a secondary shaft. The working cycle is interrupted in the individual cylinders by disconnection of the ignition and injection process.
Patent DE-2659571-A1 (DE)
Title: Automatic search program for preselected sound sections in tape - uses sound tape with marking between end of one and beginning of next sound section
Inventor: BRENDEL DIETER DIPL ING
IPC: G11B27/30
Filed: 1976-12-30
Abstract: The marking on the magnetic tape produces a marking pulse when a scanner moves past it. It causes reversal of the direction of movement and then, when it occurs again, it causes the tape finally to stop. In the searching operation the marking is made to oscillate round the scanner and the marking pulse causes momentary reversal of the direction of movement of the tape. During oscillation in the alternating braking and accelerating phases an interruption of acceleration occurs in the latter and the set is switched to stop or reverse spool direction for a certain time. In a switch to reverse spool direction the time interval is fixed so that the direction of movement of the tape is not changed.

IPC: B21H3/06
Filed: 1977-06-22
Abstract: The screws are manufactured by means of two rolling dies (1, 2), in which the profile (8) of the screws is cut. The dies are pressed from either side against the raw material and moved relative to one another. The raw material used has round section and is longer than the screw which is to be made.
