Patent FR-2184075-A1 (FR)
Title: Textured yarn having two multifilament strands - which are combined after false twisting and heated to modify the crimp
IPC: D02G1/02
Filed: 1973-05-10
Abstract: Two multifilament synthetic strands are advanced along separate paths and heated e.g. by a double face and false twisted e.g. by passage through pairs of twist bushes to impart a crimp. The two crimped strands are then combined into a yarn by e.g. passage a lapper or passage around feed and separator rolls, and the yarn is subjected to a secondary heating by e.g. passage around a multi-pass heater to modify the crimp level. The combined denier of the strands is equal to the total denier of the finished yarn or pref. the strands contain equal numbers of filaments and are of the same denier. The strands may be drawn on the same drawing device before the first heating and the strands may be fed from separate supply packages or from a melt spinning device. A lar ge denier (150 den.) yarn is formed more quickly by carrying out some processing steps on smaller denier (75 den.) components before combining the components.

Title: Traffic-bearing surface for concrete structures - with a concrete base layer and a cold-polymerisable resin-bound surface layer
IPC: E01C7/35
Filed: 1973-05-30
Abstract: A traffic-bearing surface for concrete structures (bridges, viaducts, tunnels, etc.) comprises (a) a concrete profiling layer fixed to the surface of the concrete structure by means of an adhesive layer of polymerisable resin, (b) a surface layer comprising a mixt. of aggregates, sand and filler in a cold-polymerisable resin binder which, after polymerisation, has an elongation of >30% at -10 degrees C and a tensile strength of >25 kg/cm2 at 20 degrees C (AFNOR NF T 51034), the surface layer having a modulus of elasticity of >20,000 kg/cm2 at -10 degrees C after polyermisation of the binder, and (c) surface-roughening elements projecting through the surface layer. The surface has a much higher wear resistance than conventional bituminous concrete; it also acts as a sealing layer since any cracks in the structure (provided they are no more than 0.8 mm wide) are not transmitted to the surface.

Title: Endless conveyor indexing drive mechanism - has chains thrust against peripheries of driving wheels to prevent slippage
IPC: B65G23/38
Filed: 1974-08-14
Abstract: The mechanism is for use with metal chains etc., where the transporting chains are parallel to each other and hold a film of plastic with receptacles formed in it, passing through a food-stuffs or pharmaceutical products packing machine. The chains are driven in synchronism by wheels round which they pass, angular movement of the wheels being converted into an indexing movement of the chains. The chains (2) are thrust by a number of forces against an arc-shaped contact surface on the peripheries of the wheels (1), the forces being perpendicular to this surface. This prevents any slippage between the wheels and the chains or other components.

Title: Carding device is completely enclosed in an evacuated housing - trash is removed and prevented from building up
IPC: D01G15/82
Filed: 1974-11-13
Abstract: A carding machine is completely enclosed in a housing which is evacuated e.g. by connecting a suction to outlet ducts whereby trash (e.g. waste fibres dust) is removed through the ducts. Air is sucked into the housing through apertures in the housing through which e.g. drive shafts of the carding or worker rolls etc., pass so that trash is prevented from a accumulating on the shafts and their bearings etc. Trash is effectively removed and prevented from building up and the suction does'nt damage the loop being carded.
Patent FR-2288261-A1 (FR)
Title: Self regulating fluid control valve - float which rises under increased pressure reduces flow
IPC: G05D7/01
Filed: 1974-10-14
Abstract: The vertical cylindrcial inlet block (1) of the valve has an upper, rectangular section recess (4), and a small axial through hole (2). A top cover (7) screws externally down onto the lower block trapping an intermediate rubber disc (8), both having coincident axial holes. In the cavity between lower block and disc slides a brass piston (5) with eccentric holes (6). As the feed pressure through the hole (2) rises, the valve is lifted against the disc, blocking off part of its through holes and so reducing the fluid flow. The valve may be used for irrigation or sprinkling.

Patent FR-2293833-A1 (FR)
Inventor: DUBOSE CHARLES R
IPC: G01N35/02
Filed: 1975-12-05
Abstract: The measuring device (10) described is used for the simultaneous and automatic analysis of a plurality of substances contained in blood. For this purpose, predetermined amounts of blood serum are mixed in containers (22) with appropriate reagents to form solutions. A heating block (18) with openings (20) for the containers (22) is arranged in a test area (12). Channel buttons (24), operating keys (26), an area (28) for instructions and data displays, two clocks (30, 32) for setting times, a calibration card (34) and the corresponding electronic circuits are arranged in a control area (14). The container (22) is inserted into an opening (20) and irradiated by light. The measuring device thereupon automatically reads the radiative energy absorbed by the mixture and calculates the quantity of the particular substance. This calculation is based on results from an "empty test" and a "referencing test". In the empty test, it is a voltage supplied by the absorption of radiative energy of the reagent itself which is measured, and in the case of referencing measurement is made of a voltage supplied by the absorption of radiative energy by a mixture having a known quantity of the substance. The computer provided in the measuring device is designed for correcting the interference factors occurring due to restrictions and variations of the components, and this lends the device a good resolving power.

Title: Heat exchanger esp. for air-cooling power plant fluid - has serpentines enclosed by embossed aluminium plates forming air passages
Inventor: MOLINA CLAUDE
IPC: F28D1/047
Filed: 1976-01-19
Abstract: A heat exchanger, esp. for cooling a fluid by means of air in a thermal or nuclear power plant, is built up from sub-assemblies in the form of rectangular plates. Each sub-assembly consists of a serpentine tube of aluminium or stainless steel, arranged between two plates of aluminium alloy, parallel to each other and having on their outer surfaces bosses with a flat top. The subassemblies are positioned one above the other, resting on the tops of the bosses, in batteries. Each battery has two manifolds to which the serpentine pipes are connected. The bosses are laid out in four-cornered figures with a boss at each corner and one at the centre, and the bends in the pipes of one sub-assembly are offset relatively to those of its neighbours. The exchanger copes satisfactorily with liqs. having a high surface tension, since there is little pressure loss in the piping circuits and it is arranged in easily handled blocks.
