Title: Constant pressure type fluid pump - has piston crank gear adjusted by electro-hydraulic servo valve
Inventor: KAMPMANN HELMUT DIPL ING
IPC: F04B3/00
Filed: 1974-05-30
Abstract: The pump has a cylinder containing two opposed pistons each driven by a crankshaft. Each crankshaft carries a chain wheel and an endless chain runs over both wheels. Positioning motors move the chain so as to vary the relative phase of the crankshafts and thus adjust the pump output pressure to keep it constant. The positioning motors are hydraulically operated and supplied with oil by a pump through a servo valve. An electric pressure transducer is connected to the pump discharge and provides the signal which positions the servo valve. An electronic amplifier can be placed between the transducer and the servo valve. The valve has two coils which deflect a plate controlling the oil flow to the valve cylinder.

Title: Impact absorbing chassis for lorry - transfers momentum of load into vertical movement by limited movement shock absorbers
Inventor: YAMANAKA AKIRA
IPC: B60P7/16
Filed: 1974-09-11
Abstract: The load surface of the lorry is joined to the chassis by energy absorbing elements with plastic deformation under impact. Wedge supports (6) between the chassis and the load surface interact to lift the load surface when the impact force exceeds a set amount. The upwards movement of the load surface is limited by a first set of stops (75, 76) while the rear of the cab is protected by a second set of stops (8) to prevent the load surface from striking the cab. The rear of the lorry is fitted with a shock absorbing bumper (7) to absorb limited impacts. The system enables loaded lorries to be stopped on impact without the load crushing the cab, and without the momentum of the load increasing the damage on the cab.

Title: Electrophotographic copying machine - allowing several prints from a single transfer-master
Inventor: KAWAKAMI TOUHEI
IPC: G03G13/056
Filed: 1975-02-21
Abstract: The electrophotographic copying machine uses a transfer-master which retains its polarization after the polarizing field has been removed. The transfer-master is prepared from an oxide mixture known as PLZT, i.e. a sintered mixture of PbO, La2O3 and TiO2, which is brought to a condition where a change from a ferroelectric phase (capable of holding electric charge) to an antiferroelectric phase or vice-versa can be induced electrically. This allows the transfer-master to be held polarized while the required number of copies is taken, and then restored for re-use. A more elaborate version of the machine provides for automatically taking a pre-set number of copies from a single original.

Title: Aerospace vehicle with electroturbine jet propulsion - comprising hydrogen filled superconducting coils for space or atmospheric flight
Inventor: SCHWENTEIT BRUNO
IPC: B64C39/00
Filed: 1975-07-03
Abstract: An aircraft or space vehicle has an electro-turbine drive comprising electrical batteries equipped with four super-conducting coils consisting of aluminium pipes contg. hydrogen. Combustion chambers receive solar radiation and project hot compressed air by means of hydrogen-oxygen propellant onto turbine blades. These turbine blades produce a reaction or thrust by ionised air, ejecting the hot waste gases from the combustion chambers to drive the aircraft. For flying above the atmosphere, solar energy is focused by lenses into the combustion chambers, where it generates ions, which when mixed with electrons in neutralisation zones are accelerated. A plasma comprising an ionised gas contg. more than 50% of charged particles contributes to the acceleration by passing through a magnetic field. Pref., nuclear energy is used to heat a propellant such as hydrogen or water in the combustion chambers, which is directed through nozzles onto the turbine blades. Hydrogen-helium propellant may be used.

IPC: G01R31/25
Filed: 1975-10-14
Abstract: The method is for testing the ability components arranged in a vacuum, in partic, of electrodes in electron tubes to withstand high voltages by producing voltage discharges is improved to enable reproducibility of charging rate and output voltage and automatic operation. A high voltage source (H) is applied to the test specimen tube (P) via a high impedance resistor (Rv). The capacitor (Cp) charges up until a sufficiently high voltage is attained to cause a discharge in the tube, when the discharge voltage is recorded. The applied voltage increase rate is between 1 and 100 Kilovolts per second. After discharge has occurred the voltage is reduced to the low starting level at a rate greater than 5 Kilovolts per millisecond. The capacitor is replaced by a voltage-controlled ballast tube.

Title: Stabilised suspension for twin axle - with sliding fitting of axle on leaf spring to eliminate brake reaction
Inventor: ROLLFINKE GERHARD
IPC: B60G5/047
Filed: 1975-11-13
Abstract: The twin axles are sprung on separate leaf springs (6) with their adjoining ends clamped by a yoke (10) between the axles to compensate for deflections of either axle. The outside ends (6") of the leaf springs are in sliding clamps. The axle mountings are on sliding fittings so that braking reactions do not twist the springs, while the axles are further supported at the ends of trailing arms (2). The axle clamps (7) on the leaf springs comprise rollers clamped above the springs and notched cams underneath, to engage grooves in the underside of the springs. If the braking reaction exceeds a set value then the twisting of the clamps disengages the grooves and allows the clamps to slide.
