Patent FR-2492388-A1 (FR)
Title: Continuous prodn. of particulate PVC - by feeding monomer and particulate seeding agent through reaction zone with stepwise advancement of growing particles
Inventor: GROSSOLEIL JACQUES
IPC: B01J8/16
Filed: 1980-10-22
Abstract: Continuous prodn. of vinyl chloride (co)polymers comprises gas phase polymerisation of the monomer in at least one polymerisation zone in the presence of a seeding agent (I) and a polymerisation initiator, by simultaneously and continuously introducing the monomer and particles of the (I) into the reaction zone and maintaining the polymerisation temp. of the mixt. in the zone whilst continuously removing polymer from the zone. During the growth of the (co)polymer particles they are maintained in the form of a thin layer and move down the reaction zone in small successive leaps such that at the outlet from the zone the (co)polymer particles have had virtually the same residence time in the reaction zone. Process gives polymer with improved homogeneity and degassing properties.

Title: Hand-operated liq. pump - includes rope-operated slide unit travelling along depending flexible pipe, with unit wheels initiating pumping by pipe deformation
IPC: F04B43/12
Filed: 1980-11-17
Abstract: The pump is used to raise liq. from e.g. a well, and includes a flexible pipe (1) and a slide unit (2). The slide unit has two wheels (3), eachon a shaft, and is worked by a rope or cord (7) passing over a return pulley (15) and with a hand grip (8) at its other end. During use, as the cord is pulled it causes the slide unit to travel up the flexible pipe, flattening of the pipe being caused by action of the wheels. The flattening of the pipe by the wheels effects the pumping action.

Title: Continuous casting plant, esp. for copper alloys - where multipart graphite mould is pressed against cooling elements to improve heat extn., so casting speeds can be increased
Inventor: DURAND-TEXTE GERARD
IPC: B22D11/04
Filed: 1981-10-30
Abstract: Continuous casting plant, esp. for copper alloys. The plant includes a graphite mould made of two or more parts, which are pressed against cooling elements by mechanical force exerted e.g. by jacks. The force creates flexure in the parts of the mould, so they maintain close contact with the cooling elements; i.e. so the rate of heat extn. from the mould is increased. A pref. plant is used for horizontal continuous casting, where the mould cavity is formed by two graphite elements. Jacks are used to exert compressive stress on both ends of both elements so the latter flex or bow outwards, thus making excellent contact with the cooling elements. The cooling elements may contain slots next to the graphite mould, the slots contg. a heat transfer fluid. Improved heat transfer to the cooling elements means that casting speeds can be increased.

Title: Air lock chamber for sealed zone of nuclear power station - where chamber doors have linked control boxes, so one door can only be opened when other door is closed
Inventor: GAMAIN JEAN-MARIE
IPC: G21F7/005
Filed: 1981-11-04
Abstract: In the wall of a sealed zone is a chamber formed by a tubular casing. Each end of the casing is provided with a frame, which supports a hinged door. Each of the two doors can be opened or closed by a jack, whereas a second jack (I) is used to lock each door. The two second jacks (I) are each operated by a hand lever linked to a control box mounted in the frame at each end of the casing. The two control boxes each contain meshing pinions and an air valve; and are connected together by a link rod. The link rod and control boxes ensure that one door can only be opened when the other door is closed and locked. The air valves are used to ensure that no contaminated air can enter the chamber when the latter is being swept by clean air. Simple and reliable, and with a lower cost than similar conventional air lock chambers.

Title: Mobile sugar beet plant sampling machine - has length adjustable digging-up device and retractable for immobilising machine during sampling
IPC: G01N1/02
Filed: 1982-02-25
Abstract: The machine is comprised of a moving frame with a device for digging up the plants mounted on it. The frame moves on four wheels which support a platform and is hydraulically driven. Supports for immobilising the machine at rest on the soil while the sampling operation takes place are provided in the form of retractable props fixed, one in each corner, of a rectangular chassis. The device for digging up the plants has two plough shares mounted on a carriage which can slide along a guiding groove in the chassis. This enables the device to be displaced a predetermined length (corresponding to the desired length of sample) w.r.t. the supports, at the time of the sampling operation, by a driving mechanism which is connected respectively to the supports and the digging up device. The machine is used for sampling sugar beet plants prior to harvesting.

Title: Continuous casting using super-pressure between withdrawal steps - and reciprocation of molten metal between auxiliary vessel and mould
IPC: B22D11/10
Filed: 1982-04-16
Abstract: In a continuous casting process in which there is a stepwise withdrawal of the casting from the mould and a superpressure is produced on the forming skin of the casting at the side of molten metal at intervals between the withdrawal cycles, on completion of withdrawal the molten metal is fed from a supply into an auxiliary vessel prefilled with an inert gas. A preset pressure is built up in the molten metal inside the vessel and the casting being formed. The molten metal is moved to and fro between the vessel and supply system. Molten metal is concurrently fed into the mould from the vessel and the supply during withdrawal of a given length of casting. Used for casting ferrous and non-ferrous metals, such as light aluminium and magnesium base metals and alloys.
