Patent FR-2268222-A1 (FR)
Title: Centralised automatic lubrication system - has pump and accumulator at opposite ends of line to give reverse lubricant flow
IPC: F16N27/00
Filed: 1974-04-17
Abstract: The pump supplies lubricant to a number of distributors. When the pressure in the accumulator reaches a pre-set maximum value, an electrical control stops the pump, permitting a reverse flow of lubricant through the system. The pump is fitted with a non-return valve assembly comprising a sliding sleeve, a ball and a spring. A calibrated orifice permits the return movement of the sleeve, and a spring-loaded valve limits the output pressure of the pump. After the pump has been stopped the changes of pressure in the system can cause problems. To eliminate these, there is a low discharge pressure auxiliary lubricant container and two time controlled electrically operated valves in the main line and a branch line.

Patent FR-2229384-A1 (FR)
Title: Vaginal tampon formed from rectangular sheet - is rolled transversely in opposite directions into spiral forming cylinder
IPC: A61F/
Filed: 1974-05-15

Patent FR-2272175-A1 (FR)
Title: Gas-fired cupola furnace - using rows of water-cooled tubes across bottom of shaft for uniform melting conditions
IPC: F27B1/24
Filed: 1974-05-22
Abstract: The cupola consists of a shaft mounted above a hearth used for additional heating of the molten metal, the shaft and the hearth being sepd. by transverse, water-cooled tubes covered with a refractory and located at a sufficient distance from the side walls so that the hot gases can travel upwards and the molten metal can flow downwards. The novelty is that the water-cooled tubes are arranged as pairs, forming a "bridge", and at least two rows of bridges are used, the upper row being staggered so it covers the bridges in the lower row and rings of refractory matl. are used as the coating for the tubes. The amt. of stagger used in one row of bridges w.r.t. the underlying row is pref. 0.3-1.5 times the vertical distance between the rows. The arrangement gives even distribution of the hot gases across the entire cross section of the cupola and longer life of the bridges; more efficient operation of the cupola is achieved.
Patent FR-2246042-A1 (FR)
Title: Multiple high tension condenser units - have dielectric layer formed from polystyrene and polyester films
IPC: H01G4/32
Filed: 1974-08-28
Abstract: High tension condenser, partic multiple unit high tension condensers for use in potential multipliers for the prodn. of high voltages for television tubes e.g. 25 kV for colour television tubes, have the dielectric layer formed from polystyrene and polyester films, esp. two polystyrene films and an intermediate polyester film. Provides a plastic film dielectric condenser stable to high tension but capable of being hermetically encapsulated at relatively low cost. The multiple condenser has a considerably smaller volume and is easier and cheaper to fabricate than known equipment but without loss of dielectric strength. Coating films of aluminium foil, thickness 1-6mu are used with polyester films, thickness 20-30mu, placed between pairs of polystyrene films, thickness 3-40mu. The polystyrene films are made wider than the polyester film and successive coating films project with respect to each other.

First and second directive couplers are each shunted by a power diode short circuiting device. Depending upon the control of the two short circuiting devices the first and second couplers connect the transmitter and the aerial to the first channel or to the second channel. The device has two further couplers connecting the first two couplers to the second channel.
Patent FR-2246732-A1 (FR)
Title: Air cooled engine without crankshaft - has hydraulic ignition regulator and has integral hydraulic power output piston
IPC: H02K7/18
Filed: 1974-09-30
Abstract: The engine has two or more externally cooled cylinders horizontally opposed and each containing a piston connected by push rods to a hydraulic piston arranged between the push rods. The hydraulic piston is reciprocated inside a cylinder containing a fluid used as a power output which is also used to regulate the ignition. Direct drive of a hydraulic motor is possible; complication is reduced by dispensing with a crankshaft during a separate hydraulic pump. The ignition in the two cylinders can be timed as required, and the stroke and compression may be varied. This gives increased flexibility of operation.

Patent FR-2293589-A1 (FR)
Title: Windmill with hinged blades - has inclination adjusted by screw mechanism rotating meshing quadrants
IPC: F03D7/02
Filed: 1974-12-05
Abstract: The blade is mounted on a pivot on a hub and a second blade is mounted in a similar manner but diametrically opposite. The inner end of each blade is fitted with a toothed quadrant which meshes with the quadrant of the opposite blade. These meshing quadrants ensure that both blades are inclined at the same angle to the axis of rotation. When the wind force, is light the blades are at 90 deg. to the axis but as the wind force increases the angle of inclination of the blades is reduced by means of a screw jack which rotates the meshing quadrants. With very strong winds the blades lie parallel to the axis.

Title: Dry aluminium hydroxide gels prodn - by carbon dioxide neutralisation of technical aluminate liquors
IPC: C01F7/142
Filed: 1974-12-19
Abstract: Dry Al(OH)3 gel for use therapeutically and having a high capacity for fixing acid, is prepd. by (i) removing floating impurities from an aluminate liquor, pref. having molar caustic ratio 1.6-1.8, derived either during mfr. of alumina or from technical grade hydrated alumina and NaOH soln., by sedimenting and filtering; (ii) diluting the liquor with water pref. to 20-30 g/l of Al2O3; (iii) precipitating Al(OH)3 gel with CO2 at 20-30 degrees C and 1-2.5 atm. over 20-40 (pref. is not >30) mins.; (iv) recovering the gel, washing until neutral, then suspending in water and acidifying with mineral acid, (v) filtering, partially drying, finely dividing the filtered product and finally completing the drying. The aliminate liquor used as starting material is much cheaper than the Al salts previously required. The product has acid-fixing capacity 280-320 ml of 0.1N HCl per g (dry basis) and meets the requirements of the Hungarian Pharmacopoeia for treatment of hyperacidity.
Patent FR-2264440-A1 (FR)
Title: Electronic filter for noisy analogue signals - transmits all step changes and large signals without delay
IPC: H03G7/00
Filed: 1975-03-13
Abstract: The filter consists of a first order delay network followed by a difference unit which gives the difference of the delayed signal and the input signal. The difference signal is then passed through a non-linear network, which may consist of antiparallel diodes and resistors, followed by a summing unit. The filter output gives the sum of the non-linear difference signal and the delayed input signal. The non-linear network has a true dead-zone with zero transmission of very low signals. The output amplitude is the same as the input signal amplitude. The filter is thus suitable for control with a short time constant where a normal delay filter would be unsuitable. It allows meters and recorders to give a more stable indication and reduces the demand on actuators.
Patent FR-2307980-A1 (FR)
Title: Rotational hydrostatic motor for mixing liqs. - obtaining archimedean thrust during rotation
IPC: F03B17/04
Filed: 1975-04-15
Abstract: The motor comprises two coaxial cylinders of different section with their pistons connected to each other and with low-friction "Teflon" (RTM) seals or "Bellofram" (RTM) diaphragm between the pistons and cylinders. The cylinders are fixed to the edge of a rotary disc and submerged in liq. From TDC to BDC, the larger-section piston receives a hydrostatic thrust greater than that of the smaller section piston, and vice versa. The stroke of the pistons is limited by a stop within the cylinders. The air tapped between the pistons is released into the atmosphere by a radial channel in the disc leading into the hollow rotary shaft on which the disc is mounted. The shaft is sealed off from the receptacle containing the liquid by a seal.

Title: Automatic breather valve for medical anaesthetic use - has diaphragm in rotatable sleeve which can be set to give spontaneous or assisted respiration
IPC: A61M16/20
Filed: 1975-08-07
Abstract: The automatic breather valve is used with an anaesthetic bag to give either spontaneous or assisted respiration. It comprises a body (1) with an inner chamber (2), a gas entry (3) being on the side. Opposite this is a sleeve (21), holding a diaphragm (27) in place. For spontaneous respiration, the patient breathes in through the bag and exhales.
