Title: Burner liquid fuel feed system - has burner supplied from sump with filtered fuel from decanting basin
IPC: F23K5/04
Filed: 1974-12-18
Abstract: The burner liquid fuel feed system is particularly for low-grade petroleum products. It comprises a decanting basin (58) supplied with fuel from a storage tank, and fuel in the basin is kept at the temperature necessary for pouring for a set period. A fuel storage sump (70) accommodates fuel freed of impurities after delivery into the basin. A pump transfers fuel to the basin from the storage tank, and operates dependent on the fuel level in the basin, stopping when this reaches a predetermined maximum level. A timer unit (66) monitors the duration of decantation, and when this is over empties the basin into the sump. The sump is restarted when a predetermined minimum level in the basin is reached. The burner is supplied from the sump.

Patent FR-2262428-A1 (FR)
Title: Power network fault protection process - sums and compares currents in transformers and bridges
IPC: H02H3/28
Filed: 1975-02-24
Abstract: The protection arrangement uses a system of comparing the currents in the various branches of the network. The instantaneous values of the currents in each phae are sampled by the use of current transformers. They are then summed and compared by a network of diode bridges and a comparator transformer. The difference in value of the current sums is detected across resistances and is used to operate circuit breakers. These breakers isolate the branches of the network. The circuit gives immunity against transformer defects such as saturation.

Title: Internal coating for solid propellant rocket - contg. crosslinked ethylene!-propylene! elastomer and organo-silicon
IPC: F02K9/34
Filed: 1975-04-29
Abstract: An internal coating for a solid propellant rocket contains >=1 crosslinked elastomer, a loading material and an organosilicon. The elastomer is pref. partially crosslinked, and is an ethylene-propylene-terpolymer. The organosilicon is pref. a gamma-glycidoxypropyltrimethoxysilane. The coating pref. contains 1-10 pts. wt. silane per 100 pts. terpolymer, and also 1-2 pts. wt. 2,5-dimethyl 2,5-bis(t-butyl)hexane. A palsticizer can also be present and, the loading material is pref. a carbon black. The coating is used as a bond between the solid propellant and the metal body of the rocket, whether protected internally by a thermal rubber or not. It can be placed in position by glueing layers on the internal wall, thus allowing better control of thickness. It is of low density, and simple formula, and gives good adhesion to the solid propellant. The adhesion is durable, hence coated blocks of propellant can be stored.

Title: Vehicle controller to maintain selected speed - uses tachometer and photoelectric cell to operate motor driving cam which rotates throttle butterfly
IPC: B60K31/18
Filed: 1975-07-02
Abstract: A device to control the speed of a vehicle so that it travels at a selected speed, uses a circuit to operate a reversible electric motor to drive a cam in contact with the butterfly valve of the throttle. The engine is thus slowed down or speeded up to maintain the selected travelling speed. A tachometer device controled by the driver has a disc which can be rotated so that a hole corresponding to the selected speed is brought into alignment with a photoelectric device. This is connected by an amplifier to a relay which operates a set of contacts to control the cam and motor system.

Title: Household ventilation system heat recuperator - has concentric tubes forming meander paths for hot stale air and cold fresh air
IPC: F28D21/00
Filed: 1976-03-17
Abstract: The heat recuperator is for the ventilation system for e.g. a house. A cylindrical casing (7) has a cap (19, 20) fitted onto each end. The cap (19) towards the outside of the building has a tube (2) for entry of fresh air and another tube (3) for discharge of stale air. The cap (20) towards the interior has collector tubes for stale air and a discharge tube for delivering fresh air. The cylinder between the caps has a large number of concentric tubes (8, 10) through it. A set of spacers (9) is fitted between the tubes at one end arranged in every second gap, so that the spaces between the tubes are alternately blocked and open. Another set of spacers is fitted in alternate spaces at the other end so that fresh air follows a meander path between the tubes, separate from the path taken by the hot stale air. Thus incoming fresh air is warmed by heat exchange between the tubes by the stale air as it is discharged.

Title: Petrol ignition system in internal combustion engines - projects gaseous jet across sparking plug electrode to increase speed of flame spread
Inventor: WAINWRIGHT BASIL
IPC: F02B41/00
Filed: 1976-08-12
Abstract: The system is applicable to engines having one or several cylinders equipped with sparking plugs. The ignition system uses a means which is designed to project a gaseous jet across each spark plug electrode when a spark producing voltage is applied to the sparking plug. The gaseous fit is formed from the products of combustion of the engine. The system also uses a gas accumulator which is connected to the gas projection means. The gas accumulator discharges the combustion products so that the gas jet can be formed. The accumulator is a pressurised reservoir. The reservoir connects orifices in a first and second engine combustion chamber. The orifices are designed to project gas across the spark plug in each chamber.

During manufacture, at least two alignment holes are drilled in the head for each tooth (19A, 19B). The worn mounting is removed, and an assembly jig (20) is used, accommodating the replacement mounting and with adjustable bars fitting in the holes. The bars are adjusted to a set distance apart, and after engagement in the holes the jib is set to a predetermined angle and the replacement mounting is fixed to the head.
Patent FR-2376308-A1 (FR)
Title: Sliding vane rotary compressor - has opposing vanes connected by tension springs to minimise centrifugal forces
IPC: F01C21/08
Filed: 1976-12-28
Abstract: The sliding vane rotary compressor has a rotor (2) with stub shafts (5) running in bearings (6). The rotor has four equally spaced radial slots (9) which form guides for the sliding vanes (3, 3'). Each pair of opposed vanes are connected to each other by tension springs attached to guides (14) which run in holes (12) in the centre of the rotor. When the rotor rotates, the vanes are forced outwards by centrifugal force against the housing bore. By connecting opposite pairs vanes the centrifugal forces are very nearly balanced so that there is less friction between the tip of each vane and the cylinder bore. This results in a considerable increase in the mechanical efficiency.
