Patent FR-2496119-A1 (FR)
Title: Diesel fuels based on gas oil and methanol - contg. lower alkyl fatty acid ester
Inventor: GUIBET JEAN-CLAUDE
IPC: F02B3/06
Filed: 1980-12-15
Abstract: Fuel compsns. comprise 20-90 vol.% gas oil, 5-60 vol.% methanol and 5-60 vol.% of one or more 1-3C alkyl esters of 6-22C satd. or unsatd. fatty acids. When the esters are derived from 14-22C unsatd. fatty acids (e.g. from colza, soya, cottonseed or palm oil or lard), the compsns. pref. contain 20-90% gas oil, 5-20% MeOH and 5-60% ester. When the esters are derived from 6-14C satd. fatty acids (e.g. from coconut or copra oil), the compsns. pref. contain 25-70% gas oil, 10-50% MeOH and 20-60% esters. The esters improve compatibility between the gas oil and MeOH, provide cetane nos. suitable for diesel engines, and allow satisfactory viscosity levels to be maintained.

Title: Prodn. of shelled hard boiled eggs in vending machines - and restaurants, by microwave cooking pre-shelled egg in egg-shaped mould
IPC: A23L15/10
Filed: 1981-02-03
Abstract: From a supply of raw eggs, each in turn is carried to a cutting station, e.g. by a pair of mechanical jaws. The shell is slit open centrally and the two halves of shell pulled apart for disposal while the edible egg, complete in undamaged vitelline membrane, is dropped into the cavity of a cooking mould. The mould cavity is egg-shaped and is made of material transparent to electromagnetic radiation. The mould cavity inlet is hermetically sealed and the mould subjected to microwave irradiation so that the egg is pressure cooked to hard-boiled condition within the mould. The cooked egg is finally demoulded. The process can be incorporated in the coin-actuated cycle of a vending machine for hard-boiled eggs. Each egg can be dispensed in an individual plastic tray complete with condiment and paper napkin. For restaurants etc., a number of eggs can be simultaneously processed in a multi-mould machine. The prod. has a true egg-shape and appears to have been cooked in its shell. Cooking is very rapid, e.g. a complete cycle of 45 to 60 secs. only. The edible egg is heated, so cooking energy is reduced to a min. The complete process can be automated.

Title: Electronic resistance heater for e.g. billiard table - uses array of low value power resistors used as volt dropping resistors in electronic circuits to heat surface
IPC: A63D15/00
Filed: 1981-02-13
Abstract: The electric heater uses an array of series connected resistors of the type commonly used in electronic circuits as power resistors. The resistor array replaces the wound resistance wire heating elements conventionally used in electric heating. The resistors range in value from 1.5ohm to 6.8ohm and have a power rating of 10 watt, and are of the type used as volt dropping resistors in electronic circuits. The resistors are series connected and mounted on a support surface. By variation of the number and combination of resistor values chosen, the power rating of the heater is closely controllable and the low level power density makes it suitable for warming a surface.

Title: Vibratory abrasive finishing machine tool - uses frame on resilient supports to mount stacked plates with cavities for work in abrasive grit
Inventor: KOVSHIK ANATOLY VASILIEVICH
IPC: B24B31/06
Filed: 1981-02-18
Abstract: The vibratory finisher uses a frame (3) on resilient supports (2) to mount a vibration-generator (4) and containers (6) for the work (a1) together with the abrasive grit, to finish relatively small tool parts. The containers take the form of cavities incorporated in one or more plates (5), their size being related to that of the work. The plates may be stacked (C,D) and may incorporate cavities in one major face only, and may be stacked with cavities facing the same way. Grooves (13) in the major face may connect the cavities and lead to a passage (12) connected to a suction source, the inter cavity connection may be achieved by a major face recess, and cavities may also be formed by cups located by plate perforations.

Title: Portable solar water heater - has two way non return valve with flexible plug for water to be heated
Inventor: DJELOUAH SALAH
IPC: F24S10/50
Filed: 1981-02-27
Abstract: The water heater is hemispherical in shape with a hollow shell filled with water (7) to be heated. The majority of the curved area has a heat absorbant surface below which flows the heating fluid in the jacket (5). The heating fluid circulates through circuits (12,14). The container is insulated (13) below the absorbant surface underneath (5) and around the filling plug (2,4). A two-way non-return valve (15) is fitted in each heating fluid duct. The change in the sense in which the non-return valve operates is achieved by compressing the heating fluid which compresses the flexible plug in the non-return valve and causes it to sink.

Patent FR-2482819-A1 (FR)
Inventor: ELLIS STAFFORD MALCOLM
IPC: H05K7/14
Filed: 1981-05-15
Abstract: A clamping arrangement for an elongated part (15) which extends between two opposite, parallel walls (11). The mechanism contains a multiplicity of displaceable elements (35) which are held in a uniformly stacked arrangement inside a cage (37). The displaceable elements alternately touch a metallic strip (61) on the elongated part (15) and an inner surface of a housing (51). A lever (45) which is supported on the elongated part such that it can pivot results (if it is operated in one direction) in a pressure being exerted on the outermost one of the displaceable elements, which pressure is transmitted to all the elements. The elements in consequence carry out a relative sliding movement and produce equal and opposite compression forces on the inner surface of the housing and on the elongated part, the elongated part being pressed into intimate contact with one of the walls. Operation of the lever in the opposite direction results in the elongated part being released.

Title: Variable reluctance electric motor using transverse flux - esp. for driving control rods vertically in pressurised core of nuclear reactor
Inventor: GUEDJ FREDDY
IPC: H02K5/128
Filed: 1982-05-27
Abstract: The motor contains an axial rod made of a magnetic material and provided with a row of ring projections. Rod is located on the axis of a sealed tube surrounded by at least three multipolar stators inside a magnet yoke. Each stator has a pair of pole cores with segment extensions inside the sealed tube. Each extension has two projections with the same length and pitch as projections; but the spaces between the stators is such that two adjacent projections can only be aligned with one stator at any one time. By varying the electric current in the coils wound on the stators, rod is driven axially inside the stators, e.g. to raise or lower boron carbide control rods in a reactor. The present invention constitutes an improvement w.r.t. the motor described in FR 1455472.

Title: Compound anemodynamic motor with its applications to propulsion
IPC: F03D9/00
Filed: 1982-09-27
Abstract: The invention is a wind machine motor consisting of two rotors with coaxial vertical shafts. The external rotor with its twenty four vanes directed at 50 DEG with respect to the radial vertical planes directs, in all azimuths, the wind onto two of the six vanes of the central rotor, the rotation of which, in a specific direction, generates a centrifugal gyrating flow which leads to the rotation of the "stator". The drive force generated is doubled and may be transmitted to a single drive shaft, by a differential bridge. Driving submerged or airborne propellers, or wheels, this motor may serve to propel ships, airships or motor vehicles.
