Title: Mould interior protection - by using metal powders on substrate screen
IPC: B22D7/12
Filed: 1971-04-06
Abstract: Device for protecting the inner surface of an ingot mould or other mould during coating consists of a screen of >=1, pref. 2 materials which melt or burn when in contact with the molten metal without adding impurities to it. One of the layers of material usually contains finely divided metal. By melting/burning when in contact with the metal the screens prevent the molten metal from splashing the mould interior and thus avoid the creation of defects. Metallic powders are evenly distributed when the metal rises in the mould and by varying the thickness of the powder layer each mould can be protected according to its needs.

Title: Ignition device for rocket motors - with solid propellants
IPC: F02K9/95
Filed: 1972-01-07
Abstract: Device is intended for rocket motors in which the propellant is a solid block of fuel contng. the constituents necessary for developing the combustion process; it is also suitable for hybrid rocket motors in which a complementary fluid is added which is capable of reacting with the solid fuel once ignition is initiated. The device is connected to the centre of the end-wall of the motor and comprises an injector which opens into the central channel running through the fuel block. In this way the liq. fuel sprinkles the upper region of the ignition surface of the fuel block. Safe storage is provided for the fuel liq., such as chlorine trifluoride; the appts. can be reused after certain tests. The liq. is stored in a variable space delimited laterally by a stainless steel bellows, by a destructible copper membrane and by a piston. The displacement of the latter is effected by the press. of the gas produced by the combustion of the charge of a pyrotechnic initiator which is connected to a source of electric potential.

Patent FR-2198769-A1 (FR)
Title: Continuous production of mesh filter elements - from 2 continuous bands of mesh which are joined and cut to form element on former
IPC: B01D29/00
Filed: 1972-09-08
Abstract: Mesh filter element from thermoplastic material such as nylon or polypropylene is made around circular former. Two rolls of mesh are joined and tensioned to form taught cover around the former. This then moves forward, taking the mesh with it, into a welding head where a second join is made behind the former, thus forming a circular element from two semicircular portions of sheet. the former then moves forward again into a cutting head where the weld is cut through the centre, leaving the element intact but also leaving the two bands of mesh joined. These then spring back on to the next former, since they are continuously tensioned, and the cycle repeated.

Title: Hydraulic damper for loom weft picker - includes spring biassed piston mounted in an oil bath
IPC: D03D49/38
Filed: 1972-11-24
Abstract: An hydraulic damper for damping movement of, eg. a picking stick or a weft picker (of a shuttle-less loom), includes an oil filled cylinder mounted in an oil bath contained within a housing and a piston which is slidable within the cylinder and which is biassed by a spring to move out of the cylinder. The base of the cylinder is connected to the oil bath via a throttle and a non-return valve. When the picking element moves it engages and moves pref. a roller connected to a pivotal arm by a bell-crank, whereby the pivotal arm presses the cylinder (against the action of the spring) into the cylinder and oil is forced out of the cylinder, through the throttle and into the oil bath. The non-return valve may be a ball-valve and the throttle may comprise a narrow duct into which the end of an adjustable screw extends to form a throat. The device is compact and produces good ddamping of the picking element.

A claimed fattening process comprises administering increasing amounts of the new feed to animals (esp. swine), starting at 6 weeks or later, for 14-15 weeks until ready for slaughter.
Patent FR-2273137-A1 (FR)
Title: External low density durable insulating coating for masonry - mixed with water, is simple to apply in varied colours
IPC: C04B28/02
Filed: 1974-05-28
Abstract: External coating for masonry made in powder form in the factory and needing only the addition of a specified amount of water, therefore avoiding the risks involved in making up on site. It can be applied by an conventional method, ensures good heat insulation, can be coloured to eliminate the need for painting once in place and can be applied to any type of surface. It has a low density because of the use of a mixture of light mineral aggregates and a composite binding material; the fact that a foam made from volcanic rock such as rhyolite is added to other heavier aggregates gives the coating durability necessary for external use. The cohesiveness of the coating is ensured by the use of a mixture of hydraulic binding materials and powdered polyvinyl acetate.
