Title: Hydraulic pump with toothed interior rotor - has pinion rotating around eccentric bronze bush and engaging rotor teeth
Inventor: PERRET JEAN
IPC: F04C2/10
Filed: 1980-09-05
Abstract: The gear pump includes a casing (1) having inlet and outlet points (2,3).The rotor (7) has ten teeth with straight flanks whereas the free pinion (5) has seven teeth with profiled flanks. A sealing crescent (6) prevents any short-circuiting of the fluid. The pinion runs on a bronze bush (10) permitting a higher speed of rotation and this together with the deeper tooth form provides a pump with a high flow and pressure characteristic. The teeth of the pinion have a thickness which is equal to two thirds of their height and the interior dia. of the pinion is 0.4 times the outside dia.

Title: Hybrid seed for pepper production - has female plants pheno-type normalised and male sterility artificially produced by gametocytes
Inventor: DASKALOV STEFAN HRISTOV
IPC: A01H1/02
Filed: 1980-09-10
Abstract: The pepper plants are produced by hydridisation to give a guaranteed 100 percent purity of the hybrid F1 seed. The procedure consists of crossing female plants which have been normalised by phenotype, this effect being produced by exposure to an ionising light source, such as ultra-voilet, and by increasing the temperature of growth. The growth is stimulated by the use of bio-chemical and by changes in plant nutrition. The results are combined with a male sterility which has been artificially produced by gametocytes and also female plants of allelomorphic type.

Title: Gas engine and compressed gas power system - uses stored solar heat energy and atmospheric fluids e.g. air or water to increase power output
IPC: F02C1/05
Filed: 1981-02-27
Abstract: The gas engine operable with compressed qas, such as the compressed gas from the compressor, is also fluid jacketed to be able to cool ambient temperature atmospheric fluid so that fluid yields its heat energy to the compressed gas to provide a greater power output than the potential energy in the compressed air alone.S Cooling of the compressor has the advantage of reducing the load on the prime mover and in addition to providing a useful product of heat energy. Heating the gas in the gas engine has the advantage of increasing the energy output of the gas engine in addition to producing a useful product of cool fluid. Energy from the power generation system may be usefully stored in hot water, fluid or in compressed gas and the energy of cool fluid may be used. Great efficiency is effected when used, cool, compressed gas from the gas engine can be recirculated to the intake of the compressor to reduce the energy necessary to drive the compressor in the production of compressed gas.

Title: Starter for IC engine driving heat pump compressor - uses conventional automotive starter motor supplied from AC mains through step-down transformer and rectifier
Inventor: EYERMANN MANFRED
IPC: F02N11/14
Filed: 1981-06-03
Abstract: The starter motor is used to drive the compressor of a heat pump installation is automatically switched onto the AC mains electric supply to initiate starting. The AC mains voltage, is stepped down then rectified to drive a conventional internal combustion engine starter motor. The heat pump control circuit operates a contactor (3) to connect the rectifier bridge (5) to the AC voltage (1) which has been reduced from mains voltage by a step down transformer. The rectified voltage actuates the starter solenoid (11) which engages the starter pinion (24) onto the ring gear (27) and simultaneously closes the supply contacts (15,16,18) to the DC starter motor (17). Successful starting of the internal combustion engine is detected by engine speed or oil pressure, and the AC contactor (3) opened when a set threshold is reached, so removing supply from the starter motor.
