Patent FR-2227419-A1 (FR)
Title: Window pane beading - using triangular fillet to produce tight corner joints
IPC: E06B3/58
Filed: 1973-04-25
Abstract: Beading for fixing glass in a window pane to produce a neather finish than conventional putty glazing. Normal beading when cut at 45 deg. to make a right angled joint does not produce a clean joint, so the right angle fillet removed when rabetting the frame is used. The horizontal bead (1) is cut square ended to fit exactly and the vertical bead (2) is cut at 45 deg. and overlays the horizontal at the corner giving the appearance of a butt joint. The overlap allows the beading to warp without opening the joint.

Patent FR-2261417-A1 (FR)
Title: Fuel economiser and anti-pollution device - recirculates exhaust gases through inlet manifold at low engine speeds
IPC: F02M25/07
Filed: 1974-02-19
Abstract: The exhaust pipe is connected to a non-return valve which has six small conical valve heads which are held on their respective seats by a single compression spring. The load exerted by the spring can be adjusted by means of a screwed sleeve. The downstream side of the non-return valve is connected to the engine inlet manifold. At low engine speeds the depression in the manifold allows the non-return valve to open so that exhaust gases recirculate through the engine to ensure complete combustion of the rich fuel air mixture and so reducing exhaust gas pollution. Once the device is adjusted to suit a particular engine, it cannot come out of adjustment.
Patent FR-2265227-A1 (FR)
Title: Time multiplex exchange for binarily coded signals - which have different transmission speeds and uses topographic tables
IPC: H04L5/22
Filed: 1974-03-22
Abstract: The exchange comprises an input multiplex link, with partly equal time slots in consecutive frames (frame groups) allocated to different channels with different transmission speeds, a corresponding output multiplex link a call memory for coded signals synchronous storage and reading as required for the output multiplex link and a path memory for storage of memory cell addresses in the call memory. An input transmission rate table is allocated to the multiplex links, which contains each channel transmission speed, and shows how many channels occupy the same slot in consecutive frames. The call memory has a sufficient number of memory cells allocated t these channels, addressed partly with the help from this table. Input topographic tables contain a bit place for each channel whose value shows whether the respective channel is active (engaged) or not, and memory cells in the call memory are allocated only to active channels. Addressing is done by combining contents of the input topographic tables.

Means are provided to secure the tenon to the second fitment, so it is detachable. They consist of a flange on the fitment, and a lever which is brought into contact with the flange by a lever and connecting rod actuated by a piston.

Title: Twin cylinder free piston engine - has output shaft driven through worm and wheel from piston rods
Inventor: TOTH JOZEF
IPC: F02B33/22
Filed: 1974-12-18
Abstract: The engine has two pairs of cylinders (20, 22) on either side of the output shaft (32). Each pair consists of two cylinders in line with each other each containing a piston (44, 46) which are joined directly to each other by a piston rod (108). The pistons are joined to the rod by flexible bellows (60) to give a certain amount of freedom of relative movement. Each piston rod carries worm gearing which meshes with a gear wheel on the output shaft (32). The gear contains a free qheel mechanism which ensures that the output shaft turns in one direction only. A second similar worm and wheel (108c) (110) links the two pairs of cylinders through a layshaft (112) and thus synchronises the timing of the two pairs.

Title: Filter for liquids, partic. contg. abrasive material - with low maintenance cost because of absence of sliding joints
IPC: B01D33/00
Filed: 1975-02-17
Abstract: A liq. filter, of the kind which is incorporates a cylindrical filter element, rotating in a vessel, dividing it into a feed entry chamber and a filtrate outlet chamber, and joined to two cheeks at a distance from the vessel walls, has the feed entry chamber formed by the filter element and the two cheeks, one having an opening for the inlet pipe, the other being carried by the shaft on which the filter rotates. The opening acts as an overflow in case of over-filling. The outlet chamber is divided into two compartments by an overflow wall, the height of which may be adjustable. The filter may incorporate a washing appts. consisting of jets which project a wash liquid on to the filter element and a receiver on the other side with a discharge pipe which passes through the hole in one of the cheeks. In an alternative form the cheeks are mounted coaxially around a sleeve extending from one to the other, partitioned transversely into two parts, one for the chamber formed by the cheeks and the filter element, the other for the washing appts. The filter costs less to maintain than existing filters of the same kind, partic. when treating liquids containing abrasive materials, e.g. sand or silt.

Between the different vacuum stages are rotating vacuum seals to transmit the wiping action from one stage to the next. The number of stages is optional. The wiper in one section is connected to that in the next by a system of segments mounted in Teflon (RTM) tubes of an endless spiral. The same sort of connections can be made across all the rotating seals. The inner evaporator body is divided into individually controlled heating cells corresp. to the pressure distribution in the outer process space. For use on distn. and sepn. of materials under vacuum and with an agitated heat transfer surface. The system gives multi-stage operation in a single unit which maintains the advantages but avoids most of the disadvantages e.g. blockage from degradation prods.

Title: Free wheel with pawls connected by chain - has each pawl biassed toward outer curved surface by spiral springs and fixed to inner surface
Inventor: BRAND FRANCIS
IPC: F16G13/00
Filed: 1975-11-06
Abstract: The free wheel transmits the drive from the inner member (P1) to the outer member (P2) when rotating in a counter clockwise direction. The drive is transmitted through pawls which are connected by the links (4, 3a) which fit over stub shafts protruding from the ends of the pawls. The pawls have a convex surface of constant radius in contact with the inner member (P1). The surface in contact with the outer member (P2) is asymmetricaly so that as the pawls are rotated by the spiral springs (22, 23) they create a wedging force between the members so that drive is transmitted in one direction only.

Title: Display of digital values as curves - using TV raster scanning with easy vertical positioning of several curves by synchronising beam with counter (NL150377)
IPC: G06K11/00
Filed: 1976-08-27
Abstract: A method of displaying digital values as curve points on the screen of a raster-scanning display device is designed to enable simultaneous display of several curves whilst permitting easy vertical positioning of each curve. The scanning of a t.v. screen by an electron beam is synchronised with the counting of a raster counter which controls the intensity modulation of the beam at the coordinates of curve points. For simultaneous display of several curves, each curve is associated with a reference line value to which the digital values of the curve are added. The summed values are used to determine th coordinates. By changing the associated reference line value, the vertical position of a curve may be altered.
