Patent DE-2535486-A1 (DE)
Title: Steel and concrete composite girder thrust anchor - is fitted with chord-connected steel bar shaped for force transfer into concrete
Inventor: KOSS KURT DIPL ING DR
IPC: E04B5/29
Filed: 1975-08-08
Abstract: The thrust anchor for a composite girder is firmly connected to the steel girder chord on the concrete side, whence it protrudes into the concrete. The anchor incorporates a single profiled or round steel bar (5), or more than one such bar, running continuously, parallel to the chord on on the concrete side, at an interval from it but firmly connected to it. The bar surface is profiled, to effect transfer of thrust forces from the steel girder (2) into the concrete structure (1). The configuration for this may consist of ribs, grooves, protuberances, depressions, or similar variations. Thrust forces are continuously and directly transferred, and the anchor is effective in both directions, becoming a load-sharing constituent.

Title: Easily cleaned bathroom soap holder - made in two separable parts so that cover can be easily removed while base remains clean
Inventor: WILKE RUDOLF
IPC: A47K5/02
Filed: 1975-08-12
Abstract: The base (1) is angled with the vertical lower part which is fixed by screws to the wall. The horizontal upper part has two uprights shanks. Between them is a spring tongue (8) which is reinforced by a steel spring. The cover piece (12) is in one piece and slides on to the base so that the cover edges (17) contact the wall through a rubber gasket held between the wall and the base part (1). The cover is locked into place by means of a cap-shaped push-button (20) fixed to the end of the spring - loaded tongue (8). This button (20) locates in a corresponding hole in the underside of the cover (12). This allows the cover (12) to be removed easily for cleaning while the gasket ensures that the base remains clean.

Title: Electric energy generator with closed magnetic circuit - produces pulsating flux by raising and lowering temp. of magnetic material past Curie point
Inventor: MUNK HEINZ
IPC: H02N11/00
Filed: 1975-09-05
Abstract: Magnetic flux is generated by permanent or electromagnets, and the magnetic circuit has induction coils (1, 2). Temp. changes cause pulsations of the flux. Quickly changing temperatures caused by expansion of gases or vapours in cylinders of a heat engine are used for heating the material up to its Curie temperature, followed by cooling below it. Thin ferromagnetic of ferrimagnetic foils or layers on supporting foils are used. They are spaced from each other, so that steam or gas as it flows to or from the cylinders can pass between them.

Title: Quasi-foam cleaning compsn. for textile flooring - comprises a cleaning fluid contg. thermoplastic microspheres
Inventor: PICKER CARSTEN
IPC: C11D3/37
Filed: 1975-12-10
Abstract: The compsn. is a liq. or pasty substance, which may also contain other cleaning substances, in microsphere form whose thin walls are made of a thermoplastic material (I). The compsn. is an improvement over known "dry" foam cleaning agents as the foam is more stable (and does not collapse to wet the floor) and has a high internal surface (tot ake up more dirt). It smoothes well and, as (I) itself is also non-flammable, mixes with the cleaning agent, (e.g., water or a chlorohydrocarbon) to form a non-flammable entity.

Title: IC engine with multiple carburettors - has common carburettor slow running control, suction operated from one
Inventor: SHISHIDO TOSHIMASA
IPC: F02M13/02
Filed: 1976-02-19
Abstract: The engine has several carburettors each of which has an inlet throttle (4), a main jet (5), a slow running jet (8) and an air passage (9) to the slow running jet. One of the carburettors carries a valve (11) which has a diaphragm chamber (14) connected to the downstream side (2) of that carburettor. The valve controls the communication between a pipe (10) on the inlet and an outlet (12) which has branches (21) to the slow running jet of each of the carburettors. Under normal operation air flows from this valve to the slow running jets. At low loads or when the engine is being used as a brake the valve closes, the flow of air to the slow running jets is reduced and excessive weakening of the mixture is prevented.
