Patent DE-2442466-A1 (DE)
Title: Cleaner for buccal cavity, teeth etc. - with high frequency of liquid pulses using an apertured jet pipe
IPC: A61H35/02
Filed: 1974-09-05
Abstract: Apparatus for cleaning the buccal cavity, teeth etc. comprises a pressure pipe at the end of which is a jet pipe (6) with several outlet openings (9, 10) for a jet of liquid. The flow paths leading to the individual outlet openings vary with respect to length and/or flow cross-section, causing a rapid sequence of liquid pulses to be discharged through the different openings out of phase with each other. The flow path leading to one opening (9) may be larger than the other path by providing a sinusoidal channel (12).

Title: Oil scraper piston ring - pressure spring and web design for constant polar moment of inertia
Inventor: KOERNER WOLF-DIETRICH DIPL ING
IPC: F16J9/06
Filed: 1974-09-10
Abstract: An oil scraper ring for IC engines is pressed against the cylinder wall by a spring, and also has slots round its periphery. The constant elasticity prevents the cylinder from wearing to an oval cross section with consequent performance drop and oil loss, and the ring has an almost constant polar moment of inertia over its whole periphery. This is done by ensuring that the areas between the slots are cut back on the internal surface (10). The cylindrical inner surface of the ring has a recess of half the ring height in which the tension spring is fitted. The cut back areas (10) are above and below the spring.

Title: Offshore drilling/production platform - with inclined legs resting on sea floor and joined only above sea level
Inventor: VOGEL RUDOLF DR ING
IPC: E02B17/02
Filed: 1974-11-15
Abstract: An offshore oil drilling end production platform has three or more inclined legs which rest on the sea floor and are linked to each other only near the top above water level. Each leg is as three-member space frame with tubular members so that each member can be independently flooded or emptied by compressed air.

Title: Fuel element grating of vertical orthogonal plates - composed of strips avoiding cruciform welds with top and bottom plates (SW230675)
Inventor: SULIC MILAN DIPL ING
IPC: G21C5/06
Filed: 1974-11-26
Abstract: A guide grating for rod-shaped fuel elements and control rods in a nuclear reactor comprises an orthogonal arrangement of vertical plates forming rectangular openings between them. These plates are welded to upper and lower horizontal plates having openings in them for the fuel elements and control rods (e.g. four fuel elements and one control rod in each opening). Each vertical plate is made up of a number of separate strips, end-to-end, and at every intersection (nod) only one plate is continuous, whereas the other, perpendicular plate is formed of strips which stop at that node, so that there are no cruciform weld connections, but only T-weld connections, at the nodes. Pref. the outer regions of the top and bottom plates, outside the lattice of fuel elements, are firmly connected together by vertical tubes welded into circular openings in the top and bottom plates. The grating is esp. for a water reactor. The simplified arrangement of the welds reduces weld distortion and permits wider tolerances in the cutting of the plates. Access for welding is improved.

Title: Magnetic door lock for washing machine or dishwasher - allowing door to be opened without connecting machine to mains in showroom
Inventor: BEIER CHRISTIAN ING GRAD
IPC: E05C19/16
Filed: 1975-05-17
Abstract: Magnetic door lock for washing machine or dishwasher comprises a low-retentivity magnetic component of which the former can be affected by a magnetic coil which is supplied with reversible d.c. Pref. the high-retentivity magnetic components are in the form of pole webs extending through openings in the housing wall of the machine. An earth plate may be mounted on the inner surface of the door of the machine, for cooperation with the pole webs, when the door is closed. During the operation of the machine, d.c. flows through the coil in one direction, causing the low-retentivity component to generate magnetic force which acts on the earth plate to keep the door closed, at the end of washing, d.c. flows through the coil in the opposite direction, causing the magnetism of the low-retentivity component to disappear.

Title: Hydraulic transmission for vehicle - has flywheel on variable output pump and with regenerative braking
Inventor: CAMPOMAR ARMANDO REGUSCI
IPC: B60K17/10
Filed: 1975-08-28
Abstract: The hydraulic system has a closed loop circuit with a variable output hydraulic pump and one or more hydraulic motors on the wheels. The system is powered by an engine which drives a flywheel via a first clutch. The engine operates at a fixed rate for optimum effect and stores surplus energy in the flywheel. The flywheel drives the pump via a second clutch. The variable pump then provides infinite control of the hydraulic motors, which provide regenerative braking on downhill stretches etc. and thus conserve energy. The system enables increased torque to be provided for starting etc. by draining the energy from the flywheel, to supplement the engine. In an alternative arrangement the engine and flywheel can be separate.

Title: Ink jet printing head with shut=off valve - prevents outlets sucking in air and entrainment of gas bubbles in ejected ink
Inventor: SICKING HEINRICH ING GRAD
IPC: B41J2/175
Filed: 1976-10-30
Abstract: Ink jet printing head has a shut-off valve which on the one hand prevents air from being sucked into the ink outlets and on the other hand ensures that ink free of entrained gas bubbles is not supplied to the head. A spiral spring, when positioned to allow the passage of ink, creates a capillary gap between its windings which prevent the passage of gas bubbles and serve as evaporative nuclei. The valve chamber (27) has gas outlet valves (34, 36) which permit the gas bubbles to be removed. Stops (30, 32) positioned in the valve chamber limit the deflection of the freely oscillating end of the spring and with it the lifting of the individual windings.
