Title: Mobile aluminium atomizing vessel
IPC: B22F9/08
Filed: 1970-02-20
Abstract: Installation for the prodn. of non-ferrous powders, esp. Al powder, consists of a furnace from which the metal is run in a trolley mounted holding vessel fitted with an atomizing nozzle. The trolley is moved to the atomizing station, where the metal is atomized into a receiver structure. Pref., the holding vessel is sealed after filling, tilted horizontally and compressed air is applied to the space above the melt thus forcing the metal out of the atomizing nozzle, where additionally compressed air or gas is applied in the well known manner. The process removes the uneconomic need for separate atomizing stations for each furnace and is also safer since it takes the process away from the furnace area, where great damage and injury to personnel would result in case of powder explosions.

Title: Fuel injection system - has pressure regulator to maintain decreased fuel pressure after system is switched off
Inventor: PASSERA WALTER DIPL-ING DR
IPC: F02M69/22
Filed: 1973-10-12
Abstract: The injector system has a fuel metering valve dependant upon the movement of a plate arranged in a conical section of the air inlet pipe upstream of the throttle valve. The valve has an annular groove which, opens channels to allow fuel to flow to the injector feed pipes according to engine requirements via constant pressure valves. The pressure can be varied by a differential valve which allows fuel to return to the tank according to the strength of the electrical signals given to the electromagnet by the electronic regulator. Should the system working pressure become excessive, a piston pressure regulator also allows fuel to return to the tank.

Title: Snow clearing attachment for lorry - with compact crank operated plate to couple to snow wheel
Inventor: BITTERMANN RICHARD
IPC: B60K25/06
Filed: 1973-11-29
Abstract: A flat, compact plate is fitted to the front of the lorry and has a hollow input shaft at the top end to which the output shaft of the lorry PTO is coupled via two universal joints. Two crank drives inside the plate drive a hollow shaft at the bottom of the plate where another universal joint is used to couple to the snow wheel drive. The coupling operations of the drive shafts to the plate are simply press-fit arrangements so that the equipment is speedily fitted, with a minimum of tools and manual effort. The compact design of the transmission, which can be tilted across the front of the lorry to set the snow wheel at different heights, enables the centre of gravity of the snow clearer to be kept as close as possible to the lorry.

Title: Cassette tape recorder satisfying hi-fi specifications - has large flywheel for better signal to noise ratio and less wow
Inventor: BARTOS EBERHARD
IPC: G11B15/46
Filed: 1974-02-26
Abstract: The radius of the flywheel on the tone shaft is greater than the distance between this shaft and the nearest tape spool drive shaft. Two separate motors are used to drive the two shafts, and the control mechanism for the tape drive for playback, fast wind and fast rewind is a flat unit located between the flywheel and the underside of the chassis. The flywheel diameter can be large enough to ensure that wow and flutter are reduced to acceptable levels. Since the arrangement for the working of the tape spool rotors is kept extremely flat it has enough space between the bottom of the chassis and the closely arranged flywheel.
Patent DE-2420901-A1 (DE)
Title: Cleaning system for conveyor belts - for drive and return rollers, uses continuous cleaning belt with ribbed profile
IPC: B65G45/14
Filed: 1974-04-30
Abstract: The continuous ribbed belt is guided around pressure rollers which run on bearings. The dust is removed by scrapers off the conveyor belt into side projections of the cleaning belt. Before reaching the drive/return drum, the ribs have some free space to accommodate the transported goods. When moving into contact with the drum, the apertures are sealed to enclose the goods. When reaching an upper point, the ribs re-open, and transfer the goods to a guide, which moves them to the conveying side of the belt. The cleaning belt moves at almost the speed of the conveyor belt, and due to the pressure of both belts acting against each other, caking of the transported materials is avoided.
Patent DE-2422132-A1 (DE)
Title: Compact collapsible fitting for drop-down table tops - allows table top to lie flush with surrounding furniture wall
Inventor: MANNER ROLAND
IPC: A47B46/00
Filed: 1974-05-08
Abstract: The table top support is swivel mounted with a guide rod on the fixture plate so that it can move about a horizontal axis into the closed and extended positions. The table top support and fixture plate are connected together by a weight compensating spring and a support guide rod which is swivel mounted on the support so as to be displaceable on the fixture plate and moves in two axes. In its first axis on the fixture plate, the support guide rod is displaceably mounted on a guide on the plate lying at right angles to the plane of the table top in the closed position whilst a jib arm is between the two axes for the guide rod when in the extended position. In the closed position, the table top can thereby lie flat against the front side of the adjoining furniture structure.

The l.f. signals appear as an e.m.f. in a closed circuit consisting of the sensor capacitance and biasing and leakage resistances. Potential difference across the leakage resistance is applied as an input signal to the amplifier driving the loudspeaker, and the loudspeaker diaphragm forms an indistorted size wave. A numerical example is given.

Title: Digital signal processing unit - for use with time division multiplexed data signals uses serial to parallel converter
Inventor: SUMIDA SHIZUO
IPC: B60R16/02
Filed: 1974-07-27
Abstract: The processing unit accepts as an input a series time division multiplexed, bit interleaved signal. This signal is de-multiplezed, using a serial to parallel converters, and is then presented in the parallel format to a store, where it is logically processed. The processor interrogates the signal and is used for determining the type of originating input signal, which was originally presented, and the consequent output signal which is now required. After processing the signal is converted back again to a serial stream by using a parallel to serial converter (multiplexer) and this provides the output signal.
