Title: Pneumatic antiskid device for railway vehicles - uses pneumatic speed transducers with pneumatic amplifiers to input to comparator valve which releases pressure if skidding occurs
Inventor: MASSOULIER JEAN
IPC: B60T8/32
Filed: 1981-03-24
Abstract: The antiskid device is applicable to railway vehicles and has pneumatically opened and spring closed pressure relief valves (one to an axle). Speed detectors, also one to an axle, control three position pneumatic comparator valves which are in equilibrium in their central position under pressure from the central air reservoir. The valves move into the braking position when coupled to the brake line pressure. Non-return valves prevent the reservoir, braking and speed detector air supplies mixing. The speed detectors are mounted on the end of the axle and are pneumatic transducers coupled through pneumatic amplifiers to the comparator which determines the braking requirement.

Patent FR-2503258-A1 (FR)
Inventor: KRIVKA JAN
IPC: F02D9/04
Filed: 1982-04-02
Abstract: The invention relates to an exhaust for a two-stroke internal combustion engine, comprising an exhaust duct with small auxiliary exhaust passages, a control device for the opening time of the small auxiliary exhaust passages and for the flow cross section, and an exhaust pipe. This solves the problem of insufficient exhaust cross section, the flow of exhaust gases on sealing surfaces and is of simpler construction than known devices. According to the invention the outlets of the exhaust duct and the small auxiliary exhaust passages into the cylinder wall are arranged next to one another, the small auxiliary exhaust passages being connected to the exhaust duct by means of a hollow rotary slide valve. The rotary slide valve is connected like a gear mechanism to a control device. The invention may be used on all high-performance two-stroke engines.
Patent FR-2524490-A1 (FR)
Inventor: PLATEAU JEAN
IPC: C22B21/06
Filed: 1982-03-31
Abstract: The present invention relates to a process of segregation for producing metals such as aluminum in a very high state of purity in respect of eutectic elements. The process comprises adding to a metal which is already very pure, at least one eutectic element, in a hypoeutectic amount, to ensure efficiency of the segregation operation. The added element or elements must be capable of being easily eliminated in the segregation operation, and it must not create difficulties in regard to the use envisaged for the metal. This process can be used in particular for the production, with a suitable yield, of aluminum containing less than 10 ppm of iron and silicon, and intended in particular for the manufacture of high and medium voltage capacitors.

Patent FR-2516852-A1 (FR)
Inventor: ANHORN KARL
IPC: B28B21/90
Filed: 1982-11-19
Abstract: Moulding device for concrete parts, the lower moulding part being divided into two and comprising an inner mould ring and a vertically movable outer mould ring. Both rings have upper forming areas, which supplement one another without any transition when the outer mould ring is in the moulding position for moulding the lower rabbet. Furthermore, a lower, raisable and lowerable ejecting plate is provided, on which the inner mould ring is seated. The outer mould ring is able to be supported on the inner mould ring and/or on the ejecting plate. The concrete part is demoulded by raising the ejecting plate with both mould rings, the concrete part still resting on the forming areas of the two mould rings. The outer mould ring is freely raisable upwards and designed as a two-part transporting support supporting the concrete part from the underside. The transporting away of the concrete part is performed by engaging underneath the outer mould ring and raising. The outer mould ring is demoulded to the side for reuse. The outer mould ring may also be closed, and vertically movable at least within limits. For moulding, the outer mould ring is brought into its upper position, for demoulding it is lowered. The concrete part is engaged directly underneath and transported away.

Abstract: It comprises the use of a service manipulator SM 930 and of a number of task manipulators TM 940 which are attached to elevator sockets 915 grouped around a base plate 910 by the ribs 912. The SM carries two arms mounted as shears, articulated at 936 and connected to a stationary shoulder 932 and a sliding shoulder 934. The hand 937 moves horizontally and is used to located each TM vertically in line with a socket 915, the raising of which ensures that it is clamped against the tube plate 904. The arm 945 of TM swings around an axle 946 integrally attached to the elevator trolley 944. When the arm is in the vertical position, the tool 960 and its feed block 961 are transferred on to TM by the lower hand 938 of SM. The gantry is intended to perform machining, grinding and checking operations on the tube plates of steam generators.

Abstract: Drum brake. In a drum brake, in order to best balance the braking reactions F1 to F4, the line of action 9 of the device for distancing the primary 2 and secondary 5 jaws is very oblique with respect to the diametral reference axis X-X' passing through the middle A of the primary lining 4 and in the direction of this axis when going from 5 to 2, the angle INTEGRAL being able to be about 35 to 40 DEG . The line of the centres of the articulation studs 3, 6 is a little less oblique. In the case of a trailer brake with automatic tightening when the trailer goes too fast, 5 is articulated to the stud 6 by a slot in the shape of a circular arc concentric with the axis 0 of the brake and to it is preferably associated a return spring which tends to move it in the direction I of rotation of the drum 1 for forward running, without dividing 5 into two parts.
