Patent FR-2259318-A1 (FR)
Title: Burner for high pressure liquid fuels - has mixing chamber and fixed flow reflecting diffuser
IPC: F23D11/40
Filed: 1974-01-28
Abstract: The burner enables high efficiencies to be achieved over a wide range of loads, with a minimum of noise and low pollution. The burner consists of a mixing or pre-combustion chamber (2'). This area of the burner is separated from the combustion area by a static diffuser (3) which causes a reversal in the flow of liquid fuel and air. Combustion takes place in the area (6). The injector (2) consists of a rotating sprayer, which distributes the fuel in the first cylindrical chamber. The burner may be moved axially in the pre combustion chamber to control the mixing of the air and fuel.

Title: Contouring numerical control appts - coordinates movements along multiple axes to give path motion segments at desired velocities
IPC: G05B19/25
Filed: 1974-09-03
Abstract: The numerical control system produces contouring by simultaneous coordinated motions along two or more axes. Desired-velocity signals are supplied as the primary inputs to velocity servos coupled to drive a member along the respective axes. A digital computer is physically organised and conditioned by a master program. An adjustable interrupt clock measures off successive time periods T, so as to supply a changeabl velocity command number signal to each servo proportional to the distance per T through which motion along the associated axis is to occur. This velocity command number is algebraically added to a theoretical position number to signal dynamically during each period T the axis position at which the member should reside.

Patent FR-2309737-A1 (FR)
Title: Generator using gravitational energy - has underground hydraulic turbines exhausting to double acting pumps delivering water to columns
IPC: F03B17/00
Filed: 1975-01-31
Abstract: The hydraulic turbine is installed at a great depth underground. It is supplied with water from a column with a height at level. The water flows out of the turbine into a tank at a low level, and from there flows into a double acting pump. The water is then pumped to a level above the column heights and, according to Pascal's theorem, this can be done using less power than that generated by the turbine. The water flows back through the pipes into the column to repeat the cycle. The surplus power can then be used to generate electrical power.

Patent FR-2268853-A1 (FR)
Title: Quaternary ammonium antistatic agents - for use in plastics, esp. polyurethanes
IPC: C08K5/00
Filed: 1975-04-21
Abstract: Antistatic agents for plastics have formula (I): where R1 and R2 are 1-3C alkyl, R3 = relatively long chain gp. comprising an acyl gp. bound to an alkylene chain, which opt. contains hetero atoms, on one side of a carboxyl gp., R4 = (m)ethyl or propyl gp., and Y = an anion, esp. a halide or alkyl sulphate ion such as (m)ethyl sulphate. Cpds. (I) have excellent antistatic effect when incorporated into plastics materials, and are esp. effective in polyurethanes. The acyl gp. may be bound to the alkylene chain by an ester bond or an amide bond. Preferred cpds. (I) have 2-6C acyl gps. bound via 4-6C or 15-19C alkylene chains. In a typical prepn. 4-20 C (un)satd. acid(s) stearic acid, oleic acid, etc.) are reacted with a 5% molar excess of an alpha,omega-diamine with 2-6 CH2 gps. between the two N atoms and in which the alpha amino gp. is primary and the omega amino gp. is tertiary, e.g. dimethylaminopropylamine. The mixt. is refluxed at 150 degrees C. When the acid value has fallen to 30 (4-5 hours) the mxit. is distilled to remove water until the acid value is 5. The excess diamine is then stripped off under vacuum to give a diamine CH3(CH2)A-CONH(CH2)B-N(CH3)2 where A = 4-20 and B = 2-6. This diamine is then stirred at 150 degrees C with a dialkyl sulphate such as diethylsulphate to give CH3(CH2)A-CONH(CH2)B-N(CH3)2(R) + RSO4-.

Title: Plastically deformable shock absorber - has square tubular elements weld3ed to top and bottom and intermediate plates
IPC: G21D1/02
Filed: 1976-02-19
Abstract: This method of construction of shock absorbers relies on the absorption of energy by plastic deformation and results in a compact installation. One or several square sectioned metallic tubes form the shock absorbers and are welded (5) to the upper and lower loading plates. The sections may be piled upon each other, to provide sufficient height and if so are welded to intermediate plates (3). A feature of the design is the ratio width to height of the sections which must be 2 to ensure that the force for plastic compression remains constant. The thickness of the welds between the tubular sections and the intermediate plates is equal to the wall thickness of the tubular elements.

Title: Vtol aircraft with circular wing - forces air radially outwards over ring of aerofoil section
IPC: B64C39/06
Filed: 1976-04-29
Abstract: The vertical take-off aircraft is provided with a circular wing (A) in the form of a ring of aerofoil cross-section. A fan (S) is mounted on the base (B) inside the wing (A) and covered by a hood (C). The fan draws air downwards and ejects it radially outwards over the wing (A) which deflects the airstream downwards to provide an upward force. The direction of flight is controlled by suitable control surfaces or by auxiliary engines. The load is carried in the nacelle (N) below the base (B). The circular wing (A) can be either stationary or it can rotate with respect to the nacelle (N) in which case it acts as a gyroscope and increases the stability of the aircraft.

Title: Multi-storey car park - has counterbalanced lift for cars carried on platform with trolleys to roll cars into required bays
Inventor: MARIA DEJEAN SUZANNE YVETTE
IPC: E04H6/24
Filed: 1976-06-16
Abstract: The multi-storey car park consists of a building (2) with parking bays stacked one above the other, the car being raised to the required level by a lifting platform (1) which is held in equilibrium by a cable (3) carrying a counter-weight (4). The plaform can be inclined towards the parking bays about an horizontal axis (6), by a system of levers (7). The car is parked on a wheeled trolley (9) so that inclination of the platform causes the trolley to roll into the parking bay. The floor (11) of each parking bay is also pivoted about an horizontalaxis (12) and can be inclined by a system of levers (14) causing the trolley to roll onto the platform. A retractable edge (15) prevents the accidental tipping out of a car.

Title: Foam-insulated pipe for transporting hot fluids - has rubber expansion section in its generally rigid outer sheath
Inventor: LANGENFELD MICHEL
IPC: F16L59/14
Filed: 1976-10-04
Abstract: The large-diameter pipe is covered with a thickness of plastic foam which tapers conically away to zero thickness at each end of each length of pipe. The foam lies inside a sheathing which is retalively rigid along the cylindrical length, but elastic over the conical sections: this allows for movement in the foam when the hot central pipe expands while the cool sheathing stays fixed. Pref. the foam, made by dusting a foaming material, such as polyurethane, over the pipe, has a density of 80-120 kg/m3, and is denser at the surface than in the middle; the expanding section is of rubber, clamped round the pipe. The sheathing may consist of a spiral of bitumen (or bitumen-and-elastomer)-impregnated tape with a non-woven reinforcement and with ridges round to hold the buried pipe stable in the ground; alternatively, it may be a sprayed-on layer of non-cellular polyurethane. The spigot and socket ends of the pipe are both covered with heat-resisting plastic.
