Title: Fuse using heating effect of current - has non-conducting fluid which expands to move conducting liq. to break circuit
IPC: H01H29/28
Filed: 1974-09-25
Abstract: The current limiting device has a first container (1) filled with an electrically non-conductive fluid (2) and a second container (3) filled with a gas such as nitrogen or hydrogen. The two containers (1, 3) are interconnected by an electrically non-conductive tube (5) filled with an electrically conductive fluid. Terminals (A, B) are fitted to the containers (1, 3). When an electric current flows through the device, the fluid (2) in the first container (1) is heated, expands, and displaces the electrically conductive fluid in the tube (5). Above a given value of current intensity, there is no electric contact between the first container (1), the conductive fluid (6), and the second container (3).

Title: Electromechanical game with random selection between positions - has step by step selector linked to time delay, with each step adjustable
IPC: A63F9/00
Filed: 1975-03-27
Abstract: The game gives random position selection and can be used for simulating eg a horse race. The number of horses is chosen by placing non-starter discs in sockets, the remainder of which are plugged with various resistors. Pressing a button discharges a capacitor and energises a coil and time delay and a selector advances one step. Another capacitor recharges through another time delay, affected by the resistor plugs. If the cocket is a non-starter the time delays are by-passed and the selector steps on. After a set time a contact releases and the selector stops to denote the winner.

Title: Fork lift truck unit - permits fork arms to be swivelled away whilst travelling without load
IPC: B66F9/14
Filed: 1975-05-27
Abstract: Installation for a lift and/or loading fork truck with preferably two fork arms (1), each arm (1) being swivel connected on its guide plate (9) around an axis (13) which at an angle of less than 90 deg. inclines in relation to a surface parallel to the direction of movement of the fork arms and thus to the guide bars (6). Preferably the two axes (13) are positioned remote from each other. The angle between the axes (15) and the surface can thus be such that the fork arms can be swivelled inwards towards the fork frame, but one arm can be hindered by the other, a position being reached where one arm overlaps the other.

Title: Pneumatic injector for forming extremely solid aggregates - from small particles in a mould
Inventor: MUSTO GIOVANNI
IPC: C13B50/02
Filed: 1975-05-30
Abstract: Pneumatic injection device is intended for the formation of compact, solid aggregates in moulds, starting from small particles of solid matl. Extremely compact sugar loaves are esp. obtd. The cylindrical recipient contains the matl. to be compacted; it is extended by the second recipient which converges to a conical shape with an orifice for injecting the matl. into the mould arranged below. Conduit for the introduction of compressed air into the recipient above the level of the disc is pierced with holes. If the matl. to be compacted is granular sugar, it is humidified to promote agglomeration and provide an intimate, mutual bond between the grains injected into the mould. A certain degree of fluidity is attained in the recipient by the compressed air from the pipe passing through the slits. The grains entering the mould are compressed and bonded together by their kinetic energy derived from the compressed air entering the conduit while air is expelled from the mould through the holes. The device operates easily and well; it is esp. suitable for the prodn. of solid aggregates on an industrial scale and can be used for a variety of different matls.

Title: Fluid level measurement device - has two pressure sensors, one immersed in fluid and other in air, connected to Wheatstone bridge circuit
Inventor: MATHIEU CLAUDE
IPC: G01L9/00
Filed: 1975-09-16
Abstract: The device described measures the level of a fluid and comprises one or more detectors which are sensitive to fluid pressure as a function of its level and to external parameters which effect the result of the measurement. A first detector (1) is sensitive to the pressure exerted by the fluid and by the atmosphere. A second detector (10) similar to the first (1) is sensitive to atmospheric pressure only. A differential measurement is made in appropriate electronic circuits, together with compensation for the influence of another parameter, e.g. temperature on the result. The output signal is proportional to the level of the fluid. The detectors (1,10) may be strain gauges with membranes acting as the sensitive element. The first detector is immersed in the fluid whose level is to be determined and the second detector is in free air. A wheatstone bridge system is used to determine the difference signal.

The pressure of the gas atmos. is pref. 10-3 to 10 mm. Used for e.g. treating Al, Fe, or W powders to obtain high density after compacting; also for the mfr. of Sm-Co powder magnets with good props.
Patent FR-2290940-A1 (FR)
Title: Dust removal from gases using packed filter bed - with reverse flow cleaning followed by dust separation in cyclone
IPC: B01D46/30
Filed: 1975-11-05
Abstract: Dust laden gases are purified by first passing through a cyclone to remove coarse particles then into a vessel which is divided into an inlet and outlet by a horizontal porous partition plate on which sits a bed of filter material. Dust in the gas is deposited on the filter bed and the clear gas passes out of the vessel through a 3-way valve to discharge. When the filter bed is clogged with dust the position of the 3-way valve is changed so that a flow of clean air can pass in the reverse direction into the outlet of the filter vessel and through the filter bed. At the same time the filter bed is mechanically stirred so that the dust is lifted off by the reverse clean air flow, carrying the dust into the cyclone where most of it is separated. The scavenging reverse air flow is fed into the inlet streams of a gas flow to an indentical filtering arrangement. It is preferable to have a number of such systems working in parallel so that one can be undergoin regeneration of the filter bed while the rest are working. In practice the general arrangement is for a number of these units in parallel, each unit comprising a multi-cyclone into which the raw gas is fed followed by a vessel which contains several filter beds in separate compartments, the gas flow being divided equally to each bed, but all leading to a common outlet duct. Used for purifying dust laden gas streams, e.g. flue gases before discharge to atmosphere. Reverse flow cleaning with operation of units in parallel means filtering system can work for long periods without shutting down.

Title: Automatic release for safety belt after accident - uses shock to dislodge ball sealing oil filled cylinder with spring loaded release plunger
IPC: B60R22/32
Filed: 1976-04-06
Abstract: The vehicle safety belt is automatically released after an accident, a ball (44) being dislodged by the shock and releasing oil (49) from a cylinder (48).

Title: Gas igniter with air openings - has handle and lever used to impact piezoelectric crystal and spark fed to detachable combustion chamber
IPC: F23Q3/00
Filed: 1976-03-31
Abstract: The gas igniter consists of a handle (1) and operating lever (30). Inside the handle is mounted a Piezoelectric crystal which is compressed by means of a cam and link actuated by the operating lever. The compression of the crystal produces a high tension discharge which is transmitted by an insulated wire to an electrode (4) located in the ignition chamber (7). The chamber has an opening (8) which admits the gas. Openings (10, 11, 12) admit air to mix with the gas. Another opening (13) permits excess gas to escape. The spark from the electrode ignites the mixture of air and gas. The ignition chamber and electrode are detachable from the handle.
