Title: Sheet metal with deep drawn pattern - is used for coverings of stairs or floors to prevent slipping
Inventor: LAUNAY GUY
IPC: E04C2/08
Filed: 1975-05-22
Abstract: The sheet metal has raised sections at one side which are made by drawing the material. The raised sections are in the shape of rectangles with a concave top surface. The small sides of the rectangle are raised sharply from the sheet material while the long edges of the rectangle are slightly curved, so that the centre of the surface is approx. level with the surface of the sheet material. The raised sections are made in rows on the surface of the sheet and are so placed that the diagonals of the rectangles are approx. in line. The sections can also be positioned with the concave top surfaces lying at right angles to one another.

Title: Proportional control using bang-bang circuit - compares summed actual and derivative value with desired value
IPC: G05D3/14
Filed: 1975-09-08
Abstract: A relational, in partic, a proportional, control device is designed to perform the function of a proportional controller whilst retaining the relative simplicity of a "bang-bang" controller. "Bang-bang", or all-or-nothing controllers are activated only when the controlled parameter differs from a desired value and can produce hunting which degrades the control performance. To provide proportional control from a comparator-type system the desired value from the first potentiometer is compared in the comparator with a signal corresp. to the sum of the actual value from the second potentiometer and its derivative produced by an additional circuit.
Patent FR-2323937-A1 (FR)
Title: Resilient plug stop valve - deforms locally for stick-free seating with valve body
IPC: F16K3/28
Filed: 1975-09-09
Abstract: Under compression closure a self-sealing flexible plug is withheld from valve bore passage entry. Lateral expansion into the bore would grip the plug, to inhibit free opening and increase the plug's wear. An internally derived compression localizes lateral expansion to the bore perimeter. The valve stem (20) in a screwed body sleeve (29) carries the plug (28). The stem is end flanged inside the plug. Axial plug compression, between the inside flange and an outside thrust washer (32) ridges (39) urges the plug outwards. A stem nut (24) and spring (26) in the handwheel (22) adjust the ridge height.
Patent FR-2279095-A1 (FR)
Title: Heat transfer coefficient measuring procedure - uses electrical traces, measure of power dissipated
Inventor: BECKO YVES
IPC: G01N25/18
Filed: 1975-11-14
Abstract: A procedure used to measure the heat transfer coefficient between a fluid such as air and a surface in contact with the fluid consists in measuring the quantity of heat given off by a portion of the surface, and also measuring the temperature of the surface and the fluid. The heat transfer coefficient is then calculated by determining the ratio between the heat given off by the surface and the product of surface area times and the difference between the surface and the fluid temperatures. The procedure also consists of covering the surface in contact with the fluid by an insulating sheet with electrically conductive traces or lines such that the surface is evenly covered, and in determining the power dissipated by the traces when connected to an electric source such that the temperature of each trace may be measured.

Direct prodn. of the reinforced whisker-contg. material from calcium sulphate is cheap. and no stabilisation of the whiskers against hydration is required. They have high strength and are esp. for prodn. of sheets and pipes. Foams can also be produced.
Patent FR-2340788-A1 (FR)
Title: Crystallizer positioning and displacing appts. - ensures tilt free transfer of crystalliser from ingot in electroslag remelting furnace
IPC: B22D23/10
Filed: 1976-02-16
Abstract: Crystalliser positioning and displacing apparatus includes a crystalliser with a suspension shaft and a movable carriage with grippers to engage the suspension shaft. At least two wedge-shaped abutments are provided on the movable carriage on the same size as the grippers. Wedge shaped lugs are provided on the crystalliser in alignment with the wedge shaped abutments. When the crystalliser is retained on the movable carriage the wedge shaped lugs abut the wedge-shaped abutments. The wedge shaped abutments and lugs are situated below the suspension shaft of the crystalliser. The appts. is of relatively simple structure, and is convenient and reliable in operation. The wedge shaped abutments and lugs ensure that the crystalliser is retained on the carriage without incorporation of additional permanent fasteners, e.g. bolts. As the wedge shaped abutments are adjustable, the alignment of the crystalliser relative to the ingot stool is speeded up. There is no tendency displayed by the crystalliser to tilt whilst being displaced. No jamming efforts are produced, therefore, and the wear of the internal walls of the crystalliser is minimised.

Title: Moulded portion rotary setting table transfer system - has extractor rods travelling to packing machine
IPC: B65B35/26
Filed: 1976-09-07
Abstract: The system transfer moulded portions of a congealed product from a rotary setting table to a packing machine. The moulded portions, after detachment by melting, are withdrawn from the setting compartments, which run in radial rows on the table, by means of extractor rods. After dipping in coating material if desired, they are deposited in or near the packing machine, and the rods return to the withdrawal position. As the rods return from the packing machine to the table, they travel along an external path outside an imaginary space whose height is greater than that of a standing person. The periphery of the space on the side towards the withdrawal mechanism is nearer the centre of this mechanism than the ends of the rods furthest from this centre, when these are in the withdrawal position.

Title: Automatic dough cutter with suction chamber and piston - with lower energy consumption and smoother running regardless of dough weight
IPC: A21C5/02
Filed: 1977-03-25
Abstract: Suction device for machine for automatic cutting of dough comprises a suction chamber with a suction piston for impelling the dough, and a slide which is adjusted to an orifice of the chamber and which is provided with a cylinder and a metering piston.
