Title: A complex similar to artificial leather is made by inserting between a layer of polymer, particularly a hydroxylated polyester, and a flexible or semi-rigid sup
IPC: B32B27/00
Filed: 1969-01-24
Abstract: A complex similar to artificial leather is made by inserting between a layer of polymer, particularly a hydroxylated polyester, and a flexible or semi-rigid support, fibres making an angle with the other layers and being fixed at their ends to the layer of synthetic material and to the flexible or semi-rigid support. The exterior face of the synthetic material receiving a permanent graining. The support may be floched with natural or synthetic fibres e.g. cotton, rayon, polyamides or polyesters, of 80 mesh or with a length 0.5 mm. and of about 1.5 denier, and is then brought in contact with the transfer film coated with adhesive. The process avoids embossing the grain on the sheet, the flock providing an auto-grained effect.

Patent FR-2128149-A1 (FR)
Title: Bar bending machine - continuously forming multiple spiral forms
IPC: B21F3/08
Filed: 1971-03-08
Abstract: Bending machine which can bend bars in a spiral form of >=1 turn comprises several elements which can be butted together to produce the required spiral and which stretch over about one turn. The first element at the interior has a groove for initially situating the bar to be bent and a pressure device is applied to maintain the bar in position. A drive produces a movement of the element w.r.t. the pressure device and causes the bar to bend around the element. Successively elements are axially moved upwards to abutt the previous element and further bending of the bar around the new element is carried out until the required spiral is produced. The operation is continuous and buckling is prevented.

Patent FR-2206119-A1 (FR)
Title: Mixing nozzle for plastics materials - closes inlets and self cleans as supply pressures drop
IPC: B29B7/74
Filed: 1972-11-15
Abstract: The nozzle has inlets for a medium pressure principal fluid and a high pressure subsidiary fluid, both inlets remaining closed by spring pressure until the pressure of component fluids overcomes the closure pressure. The component fluids meet in a mixing chamber which increases in vol. in proportion to the supply pressure of the principal fluid. The nozzle is self-cleaning as fluid supplies are cut off, the mixing chamber contracting to eject residual mixt. this characteristics obviates the use of inert gas and aerosols for nozzle cleaning.

Title: Capacitance gauge measures liquid flow - modified version of level gauge, gives linear output versus flow
IPC: G01F1/52
Filed: 1973-04-24
Abstract: Capacitance gauges intended to measure liquid level use a printed circuit mounted on an insulator with a second insulator forming a sandwich. The liquid acts as the other plate in a variable capacitance. When such a gauge is used upstream of a sill weir, notch weir etc., the law between discharge and capacitance change in non-liner. The law between discharge and liquid level is plotted experimentally and folded round an axis to give a symmetrical shape, and this reproduced as the printed circuit plate. The law between discharge and capacitance is now linear. For some weirs it is necessary to measure differential capacitance using a constant width plate for one and a shaped plate for the other thus compensating for non-monotomic discharge/height laws.

Title: Cableway with stationary loading - has chairs suspended by two ropes at obtuse angle to each other
IPC: B61B11/00
Filed: 1973-10-22
Abstract: The cableway is for use as a ski-lift or for handling material in bulk etc., and runs at constant and high speed. Each chair, skip etc. (1A-F) is supported from the cable (2, 3) by two ropes (8A, 9A, etc.) forming an obtuse angle with each other. Thus for a time the attachment point of the rear rope is on the downwards run of the cableway while that of the front one is on the upwards run. During this time the chair remains stationary on the ground to allow easy loading and unloading, provided the ground has been levelled off at a suitable height. As the incoming runs of the cableway reach the arrival point they do not slope downwards.

Title: Optical stabilisation element for viewing axis - concave mirror in objective image plane reflects light to gyroscope mirror
IPC: G03B17/56
Filed: 1973-12-10
Abstract: The stabilisation element is positioned in a non-parallel beam and has an input objective (2) and a gyroscope (5) having a plane mirror (4). The axis stabilised by the gyroscope is parallel to the aiming axis and perpendicular to the mirror. A concave mirror (3) which is inserted on the optical oath between the objective (2) and the plane mirror (4). The concave mirror is near the plane image of the objective and reflects light towards the plane mirror. Thus the device enables precise focussing in the centre of the field in spite of support movements. The curvature of the concave mirror is chosen to correct for the de-focussing introduced by rotation of the stabilised mirror about axes perpendicular to the stabilised axis.

Used in the production of fuel element assemblies. Reduces the fuel element assembly time by 65% with consequent reduction in exposure to active materials of operating personnel. Roller action promotes removal of dust and small particles and ensures clean assembly of fuel elements.

Title: Anti-corrosion aluminised coating - for ferrous metals with brazed joints
IPC: C23C10/60
Filed: 1974-11-15
Abstract: Prodn. of a thermally diffused corrosion protecting aluminised layer on stainless steel components with brazed joints where the braze material is a non-ferrous alloy at m.pt. 607-1052 degrees C and esp. an alloy based on Cu, Ag, or Au, with m.pt. 635-1010 degrees C, involves protecting the braze from excessive Al penetration by selectively plating it with a 0.005 mm layer of Ni. Selective plating is achieved by chemically depositing Hg on the braze, immersing in aq. HNO3 or CrO3 to remove Hg and passivate the steel, followed by electroless Ni plating which deposits only on the braze. After aluminizing, corrosion protection is further improved with one or more silicate coatings opt. followed by chromate/phosphate treatment. Used for mfg. components, e.g. for turbines, which draw in air and operate in marine conditions. Weakening of brazed joints by excessive penetration of Al is prevented.

The H2 should pref. be used at min. 3 1/minute and contain the lowest possible amt. of N2 with max. 5% H2O, and the final alloy should pref. contain, all maxima, 0.005% C, 0.015% nitrogen and 0.1% oxygen. The powdered alloy is used in the mfr. of stainless steel, the corrosion-resistance and toughness of which is improved by a redn. in the C and N2 content. Process uses a lower temp. and shorter time than similar, known processes which involve heating in vacuo and do not produce very low nitrogen contents.

Title: Temperature regulator for apartments - is controlled by time switch and sensitive element heated by resistor
Inventor: BARK DIETER
IPC: G05D23/275
Filed: 1975-02-25
Abstract: A sensitive element is heated by a supplementary resistive element to reduce time intervals due to thermal lag of the heating system around large buildings. To obtain suitable night temperatures a time switch is used in conjunction with a supplementary heating resistance and the thermostatic distributors.

The other contacts (22, 17) on the clock switch permit a resistive heating element to be switched to the mains supply (R, Mp) in series with the sensitive element. A switch (27) may be connected in series with this resistor (5).

Title: Wear minimising undercarriage wheel spin mechanism - has brake cooling air or motor to match touchdown velocity and tyre speed
IPC: B64C25/40
Filed: 1975-05-21
Abstract: The friction forces on the tyres of aircraft undercarriage wheels are reduced by setting the wheels in rotation immediately before touchdown. The tangential velocity VRA of the tyre is made equal to the forward speed VAS of the aircraft at the instant of touch-down. The brake cooling air is used to rotate the wheels at the required speed. Alternatively, for short range aircraft the rotation imparted to the wheels during take-off is maintained by a motor. The force required to rotate the wheels can be reduced by deflating the tyres after take-off and re-inflating before touch-down, which reduces the moment of inertia of the wheels during flight and build-up of rotation.
