Title: Fixture locating calibrating plug for fuel pump outlet - has disc with prongs and points penetrating plug bore wall and plug end face
Inventor: BISHAI MACRAM N
IPC: F16J13/02
Filed: 1980-11-05
Abstract: The fixture (44) is intended for locating a calibrating plug (24) in a radial bore (14) provided in the outlet duct (12) of a pump housing (10), e.g. the housing of an electric fuel pump. The fixture consists of a flat disc with a number of prongs (48) which extend in radial direction from the periphery at an angle to the disc and have their outermost ends (52) parallel to the disc.

Title: Folding box for video tape cassettes - has open top for entry of cassettes and openings in one side to permit reading of titles
IPC: G11B23/023
Filed: 1980-11-20
Abstract: The rectangular sided box has a horizontal base and four vertical sides and is formed from a flat sheet of plastics material. Tabs with rounded corners are used to close the sides after cutting and folding. The box has an open top and is of sufficient width to receive a given number of cassettes without play between them. The height of the box is slightly less than that of the cassettes. Notches in the upper edge of two opposing sides of the box facilitate removal of the cassettes while elongated openings in the lower half of one side enable the titles on the cassettes to be read. The openings also allow air to be pushed out when the cassettes are pushed into the box to fall under their own weight.

Title: High-lift device for wind propulsion of ships - uses boundary layer modifying retractable edge and aspiration zone formed by flared cylindrical body
Inventor: COUSTEAU JACQUES YVES
IPC: F03D3/00
Filed: 1980-12-01
Abstract: The device consists of a pref. steerable body (10) with a rounded thick symmetrical cross-section in the direction of the air flow (V). A rigid cylindrical envelope (50) defines a semicircular trailing edge and is associated with an e.g. semi-elliptical fairing (52) defining the leading edge. This lengthened leading edge reduces the energy requirement for creation of lift, but is vulnerable to excessively strong winds. Pref. the profile may be modified against this risk by inflation or deflation of a simple flexible or semi-rigid envelope (52a) of cloth. Significant depressions can be formed on the leeward side by a permeable aspiration zone (54) and a flap (14a) which separates the air flows on the top and bottom faces. The device is also used to generate electricity.

Title: Stirrer for liq. in agricultural spraying tank - where stirring motion is progressively decreased as level of liq. in tank decreases so liq. does not foam
Inventor: DORVAL EDMOND DANQUECHIN
IPC: B01F5/10
Filed: 1981-01-16
Abstract: Stirrer for liq. in agricultural spraying tank. In the tank is an inlet valve on the end of a pipe leading to a pump. The pump delivery pipe ends in a horizontal pipe located near the base of the tank and contg. a row of outlet holes. The flow of liq. through the outlet holes agitates the liq. in the tank. The valve is actuated by a ball floating on the surface of the liq. in the tank, so that the vol. of liq. recirculated by the pump can be decreased in proportion to the drop in height of the liq. in the tank. The pump is pref. driven at a constant speed either by a tractor carrying the tank, or by an auxiliary motor. The liq. in the tank must be stirred to ensure that the sprayed liq. has a uniform compsn. But when the level of the liq. in the tank is low, excessive agitation can form a foam or emulsion, which is undesirable. The invention restricts the circulation of the liq. when the level of the latter is low.

Title: Ascending detritus rakes for e.g. hydro electric intake screen - has rake suspended by rods and chains and making linear pick=up run over screen
IPC: E02B8/02
Filed: 1981-01-23
Abstract: The screen-cleaning machine uses ascending rakes (3) to collect detritus from e.g. a screen (2) across a water-intake channel at a hydro-electric plant. The rakes are displaced by motors and deposit detritus overhead (4), following a trajectory in the shape of a geometrical figure and making a linear ascending 'pick up' run over the screen. The rake may be suspended by rods (10) and chains (9) from radius arms to a revolving motorised shaft, or alternatively two diametrically opposed sets of radius arms may each have a rake suspended from their free ends, the shaft being horizontal and parallel to the screen.
Patent FR-2501856-A1 (FR)
Title: Fibre=optic transmission for circuit-breaker triggering - uses magnetic deflection of mass in path between fibre ends and photodetector system
IPC: G01R15/24
Filed: 1981-03-10
Abstract: Overcurrent is detected rapidly by the effect of its magnetic field on a ferromagnetic mass in close proximity to the conductor. The movement of the mass interrupts the light path between the ends of two fibre-optic cables. The output fibre is coupled to a photodetector which responds by triggering an electromagnetic or electronic relay to open the circuit-breaker. Alternatively the mass is attracted indirectly by an induction winding connected to a sensing winding which surrounds the conductor, and/or the light path is influenced by the displacement of a small mirror integral with the ferromagnetic mass.

Title: Electrochemical cell with cation conductive vitreous electrolyte - formed by powder compaction on cathode with lithium disc superimposed
Inventor: DUCHANGE JEAN-PIERRE
IPC: H01M4/36
Filed: 1981-06-17
Abstract: The electrolyte is a mixture of P2S5, Li2S and a lithium halide, in which the ratio of Li2S to P2S5+Li2S is within the limits 0.61 to 0.7, and the ratio of the halide to the total does not exceed the halide solubility in the vitreous phase of the other two constituents. The cathode is pref. a mixture of 45 wt.% Cu4O(PO4)2 with 50 wt.% of the solid electrolyte and 5 wt.% of graphite, formed in a steel matrix under pressure of about 750 kg/sq.cm. Other preferred positive active materials include MoO3, WO3, TiS2, NiPS3, Cu- or Pb bismuthate etc. The electrolyte in powder form is spread over the cathode and compressed at 3000 kg/sq.cm., and a lithium disc is placed over it. The stainless steel anode overlies an elastomer spring, through which electrical connection is maintained by two clamps.

Patent FR-2493961-A1 (FR)
Inventor: SCHUSTER WOLFGANG
IPC: F23D1/02
Filed: 1981-09-02
Abstract: The invention relates to the production of a rotating coal-dust flame in greatly cooled combustion chambers of industrial heat-generation installations. The aim of the invention is to extend the area of use of solid fuels to industrial heat-generation installations which have thus far used fuel oil and gas firing systems. The task consists in the production of a suitable process and a burner for greatly cooled combustion chambers, with which high reaction rates and thus short burn-out times can be achieved. The task is achieved by supplying a combustion chamber with air at ambient temperature by means of an axial primary air flow loaded with coal dust and tangential secondary air flows. After ignition, the flame burns without support firing. It is advantageous that the burner according to the invention can subsequently be arranged on small steam generators or the like.

Title: Washing machine for vegetables e.g. potatoes, carrots, etc. - trims, spray washes and jet rinses with optional soaking and shaking
IPC: A23N12/02
Filed: 1981-10-16
Abstract: A machine for washing a wide variety of vegetables, esp. those from which sand and/or soil are to be removed. The machine is of the type which is carried on a mobile, wheeled chassis. The vegetables are passed in sequence through a series of operations selected from trimming off leaves, spray-washing, soaking, vibration while immersed and jet rinsing. The prod. is advanced through the machine by an endless conveyor comprising two side bands joined by tubular cross bars. The path of the top run of the conveyor can be adjusted to run horizontally above a washing water tank when the prod. is to be cleaned by spraying and jet rinsing only. Alternatively, the top run can be extended to curve down into and then back up from immersion in the tank. This run is adopted when prod. soaking is required. At the lowest point of this run the conveyor can also be shaken by a mechanical vibrator. A single machine can be adapted to deal with many different vegetables. The machine is very effective in eliminating grains of sand etc. which previously would have remained trapped between leaves.
