Patent FR-2436825-A1 (FR)
Title: Free cutting steel contg. sulphur and tellurium - producing low anisotropy in mechanical properties, and good formability in cold forging, due to short length of inclusions in rolled steel
IPC: C22C38/60
Filed: 1979-09-19
Abstract: The steel contains 0.6% C max.; 2.5% max. (0.5% max.) Si; 2% max. Mn; 0.4% max. (0.04-0.4%) S; 0.1% max. esp. (0.003-0.03%) Te, and balance Fe. The ratio (R) = %Te/%S is min. 0.01, (min. 0.04). The steel may also contain (all maxima) 5% Cu, 3% Mo, 2% Al, 3% W, 2% V, 5% Co, 0.5% Nb, 0.5% Ti, 0.5% Ta, 0.5% Zr, and/or 0.01% B; and possibly also 0.04-0.25% P, and/or (all maxima) 0.4% each of Pb, Bi, Se and/or 0.01% Ca. The steel pref. contains max. 0.003% O2; and is made esp. by melting to produce a melt contg. the C, Si, Mn, and S. This steel is formed into a stream to which the Te and possibly the Pb, Bi and Ca are added, followed by continuous casting. The specified ratio (R) produces a relatively small length: width ratio (L/W) for the sulphide inclusions in the steel, so good mechanical properties are obtd. in the transverse direction in rolled prods.
Patent FR-2469758-A1 (FR)
Title: Photoelectric perforated card reader - uses matrix of IR photodiodes and corresponding IR emitting diodes or fibre optic bundle facing single IR source
IPC: G06K7/10
Filed: 1979-11-09
Abstract: The reader uses a matrix of infra-red photodiodes mounted in a multi-layer circuit on one side of the card entry and, on the other side, a corresponding matrix of infra-red light emitting diodes, or alternatively of optic fibres, with opposite end fixing a single infra-red source. When the perforated card is entered between the transmitting and receiving surfaces photo-diodes are either activated or blackened and suitable electronic decoding circuits can present this data in required form. The incorporation of a RAM allows the card to be withdrawn as soon as data is in memory.
Patent FR-2469787-A1 (FR)
Title: Electrical value of coil capacitor - is adjusted by sand blasting cavity in capacitor layers and applying priming voltage across terminals
Inventor: COIRIE PIERRE
IPC: H01G4/255
Filed: 1979-11-13
Abstract: In a method of adjusting the value of a tubular capacitor formed by winding two metallised dielectric foils together, a capacitance meter (61) is connected across the capacitor terminals and a cavity (60) eroded in the capacitor wall through several layers of foil, for example by a jet of sand, until the meter measures the desired value. A priming continuous voltage is then applied across the terminals, and the capacitor is subsequently coated in resin which fills the cavity. The unit is of the type having lateral metallisations formed on the end walls serving as contacts for the capacitor connector wires.

Title: MOvable drive plates for bicycle - are fitted on either side of sprocket to drive it via cranks
IPC: B62M3/06
Filed: 1979-12-18
Abstract: The pressure plate is for a bicycle which can take on its upper part a crank. This is placed on the other side of the crank wheel. The ends of the plate can be pushed and not just on the pedal pivots as normal. A second flat plate, similar to the first, but without teeth, is placed on the other side of the crank wheel. This gives coordination of the two cranks, which are retained on the plates by bolts passing through aligned holes in both.

Patent FR-2472959-A1 (FR)
Title: Preventing solidification of metal in casting vessel nozzles - where top end of nozzle is closed by cartridge, which is gradually destroyed by metal poured into vessel
Inventor: DAUSSAN JEAN-CHARLES
IPC: B22D41/46
Filed: 1980-01-04
Abstract: The vessel consists e.g. of a ladle or tundish with one or more bottom outlet nozzles provided with sliding stoppers. The top end of the nozzle in the base of the ladle is closed by a cartridge, before molten metal is poured into the vessel. The cartridge is closed by a base(12) and a lid(11), made of materials which are destroyed by the heat and/or pressure of the ferrous metal in the ladle, and which do not pollute the metal. The cartridge is filled by one or more refractory materials(10) which do not sinter at the temp. of the molten metal, but which fall through the nozzle when the lid and base have been melted or destroyed by the metal added to the vessel. Long and expensive preheating of the vessel to prevent the solidification of molten metal in the nozzle or stopper can be eliminated.

Title: Elastically mounted roller blind - has twisted elastic tie providing small and constant recall force for blind curtain
Inventor: DUPAYS JEAN-LOUIS
IPC: E06B9/60

Title: Multiple section lampshade making machine - has covering material rolled over frame held between supports, controlled by reciprocating piston
IPC: F21V1/26
Filed: 1980-07-07
Abstract: The machine for making lampshades supports the frame while the covering material is stretched over it. The frame is secured between an upper guide (3) and a lower guide (4) vertically in line with each other. The covering material is tensioned by inward movement of the upper guide (3) controlled by a double acting piston (1) above it. Tension is applied to the two ends of the covering material inwardly towards the middle of the frame so that it is rolled round the top and bottom edges. Then the tension is released. The two guides are carried between the opposite ends of a circular arm (2) which can tilt about a horizontal axis. These guides can be shaped to match the lampshade.

Title: Device for gluing hanger strip to drawings - has plate with openings for suspension pins and datum marks
IPC: B42F3/00
Filed: 1980-10-17
Abstract: The machine has a plate supported by a frame with openings for the suspension pins of a filing cabinet, also datum marks at regular intervals so as to be in the same relative positions to the respective oenings. It has a rectangular structure fixed parallel to the plate, allowing the insertion of a drawing on top of a strip. Each longitudinal member has a ruler for positioning the drawing in relation to the strip and for pressing both against the plate. Two markers are movable along one of the longitudinal members, one being positioned opposite a datum mark and the other at the edge of the drawing where the strip is to be parted off. This ensures that the suspension openings are in the same position in relation to the edges of all the drawings.

Title: Inspection appts. for sacrificial anodes - which provide cathodic protection for pipeline carrying oil, where oil flow drives appts. through pipe
Inventor: RAMAUT EDOUARD
IPC: C23F13/04
Filed: 1980-12-02
Abstract: The appts. consists of two drums connected by a universal joint. Each drum has a ring baffle, so it is carried through a pipeline by the fluid flowing along the latter. Each drum carries a circular wire brush insulated electrically from the drum. The two brushes are connected to a microvoltmeter measuring the electric current flowing through the wall of the pipeline due to the sacrifial anodes. One drum also carries a roller in which magnets are embedded to create pulses indicating the distance travelled by the drums. The pulses are used to correlate the microvoltages obtd. with the position of the brushes in the pipeline. Used esp. for the protection against corrosion of underwater pipelines carrying oil. Inspection can be undertaken without interrupting the flow of oil through the pipeline.
