Title: Expansible wall fastener plug - has grooved segments on ribbed core having bore for fastener
IPC: F16B13/00
Filed: 1975-02-10
Abstract: An expansible wall fastener plug consists of a core (1) of elastic material of roughly square section (6) with two diametrically opposite arms (2) and two shorter arms (5). The core (1) has a central hole (3) with a diameter slightly less than that of a fastener screw, and there are two diametrically opposite slots (4) running the length of the core (1). The core fits between two semi-cylindrical members (7), (8) forming two halves of a plug and provided with a serrated outer surface. When a screw is fitted into the hole (3) the core (1) is expanded and this, in turn, presses the two members (7) (8) against the surface of the hole in the wall and provides a secure fixing. Alternative designs use a plug made in three or four segments.

Title: Filter for liquids, partic. automobile engine oil - elastically deformable axially, obviating need of supplementary bypass valves
Inventor: YOU YVON
IPC: B01D27/04
Filed: 1975-02-11
Abstract: A cylindrical filter, partic. for automobile engine oil, is elastically deformable along its axis. The filter material is cellular polyurethane or pleated paper. The filter incorporates a shell, two base-plates connected to one another by a spiral spring, and a fixing plate with a central hole in which is secured a short tube. One base-plate is movable in relation to the shell, sliding along the short tube. The other base-plate is fired to the shell, so as to form an annular inlet chamber in communication with the short tube within the shell. The periphery of the movable base-plate rests on the fixing plate forming a non-return valve between the inlet hole and the annular inlet chamber. A by-pass opens between the inlet-hole and the interior of the filter if the firing plate becomes displaced beyond a predetermined distance from its closed position, e.g. in the event of the filter material becoming vlocked. The filter is simpler than existing filters, because it does not need supplementary valves.
Patent FR-2302273-A1 (FR)
Title: Hydrogen mfr. from steam using palladium - both as catalyst and as a membrane for selective diffusion of hydrogen
IPC: C01B3/50
Filed: 1975-02-28
Abstract: The water is heated to 100-1200 degrees C in contact with a wall consisting (partially) of a metal from the Pt family and used for the selective di fusion of hydrogen which is collected on the other side of the wall. The wall is pref. of Pd or a finely porous material contg. or coated with a Pt metal. A finely-divided catalyst may be used to decompose the water on the side of the wall where water is present, esp. a powdered metal from the Pt family. The dissociated steam may be recovered as a mixt. of H2 and O2; the hydrogen may be collected in inert gas; and the water temp. at the wall is pref. 400-800 degrees C. Due the scarcity of fossil fuels, H2 is important as a fuel. The heat is used directly without the need to convert it heat into electrical energy which entails low thermal efficiency. The process can be used with high temp. steam from nuclear power stations, or with solar energy.

A contact plate (32) is held at a distance of about one cm from the slotted upper side of the housing by means of a spring (33).
Patent FR-2287438-A1 (FR)
IPC: C07C59/305
Filed: 1975-10-10
Abstract: In the preparation of carboxymethyloxysuccinic acid, a Michael condensation of maleic acid with glycolic acid is carried out in an aqueous basic medium in the presence of calcium ions, giving the calcium salt of carboxymethyloxysuccinic acid. In accordance with the process described herein, the subsequent liberation of the carboxymethyloxysuccinic acid from the calcium salt is carried out by acidification with sulphuric acid at a temperature of between 40 and 80 DEG C, upon which process the calcium sulphate precipitates in the form of the dihydrate. Strict adherence to the temperature is required since, below 40 DEG C, the carboxymethyloxysuccinic acid and the calcium sulphate form a chelate complex which, due to its relatively free solubility in the aqueous medium results in a substantial loss in product yield, while, on the other hand, when the neutralisation reaction is carried out at a temperature of above 80 DEG C, lower hydrates, for example calcium sulphate hemihydrate, are formed in addition to calcium sulphate dihydrate, and this calcium sulphate hemihydrate results in contamination of the resulting carboxymethyloxysuccinic acid with calcium sulphate, because of its free solubility in water. Carboxymethyloxysuccinic acid and its salts are used as components of biodegradable detergents.

Title: Refining vegetable matter for animal fodder - using heated lye and crushing rollers to predigest and break down cellular structure
IPC: B30B11/16
Filed: 1975-10-10
Abstract: The nutrient value of vegetable matter such as straw is improved by treating it with a lye in an installation in which it is subjected to a flexible pressure between two motor-driven cylinders. Before the final pressure treatment, the material is thoroughly mixed with the lye and heated to accelerate the reaction. The process is non-polluting, is not labour intensive, and yields a more easily digestible product by a simple process.

The planet wheels also mesh with the internally toothed wheel (A) which is also provided with external teeth (D) which mesh with the pinion (E) of the auxiliary motor (P). The drive from the cages (C) is transmitted through the idler gears (R, R') and gears (K, K') to the output shafts (M, N). The speed and direction of rotation of these output shafts can be controlled by varying the speed of the auxiliary motor (P). The variation in speed is stepless and the ratio of output to input speed can be either increasing or decreasing.

Title: Integrating synthetic and natural gas supply systems - by using a mixed gas with a specified hydrogen to methane ratio
IPC: C10L3/00
Filed: 1975-12-31
Abstract: The prodn., processing, transport, storage, distribution and utilisation systems used for natural gas and for synthetic gas (e.g. town gas or synthesis gas) can be integrated by operating them with a mixed gas contng. >=90 vol. % CH4+H2, with an H2:CH4 ratio between 0:1 and 3:1 (pref. between 2:3 and 3:2). The costs involved in changing over from one gas supply system to another are eliminated; the capacity of existing synthetic gas systems can be increased to deal with newly found natural gas reserves, and natural gas systems can be supplemented with synthetic gas without the need to convert the latter into substitute natural gas.

Title: Pure clostripain enzyme prepn. - by affinity chromatography of Clostridium histolyticum culture or crude collagenase
Inventor: KEIL BORIVOJ
IPC: C12N9/52
Filed: 1976-02-20

Title: Logic circuit tester using electroluminescent diodes - has touch point, voltage dividers and resettable monostables to activate LED indicators
IPC: G06F11/277
Filed: 1976-07-29
Abstract: The logic circuit tester includes a DC voltage source supplying a power line and a reference test point is connected to one of the wires of this line. A first voltage divider is connected to the two wires of the power line and a first bridge containing a first electroluminescent diode, a resistance and a transistor is connected between the same two wires. A second bridge, similar to the first, is connected also between these wires. A touch point is connected, via a second voltage divider, to a point of the first voltage divider which has a potential in the interval between the highest "zero" level and the lowest "one" level. Third and fourth transistors are polarised between a point of the fiist voltage divider and a point of the second voltage divider and control the first and second transistors respectively. Resettable monostables are placed in the output circuits of the first and second transistors and a third electroluminescent diode is connected between the two outputs of the monostables. Thus this third electroluminescent diode lights up when a short pulse is framed by the same logic state.
