Title: Constant pressure liquid control valve - has graduated float passing controlled flow
IPC: F16K31/18
Filed: 1974-07-03
Abstract: The control valve described allows the passage of a liquid of given density but prevents the flow of liquids of other densities. It also acts as a non-return valve and can be used to prevent overfilling of containers. A preloaded float responds to the density of the liquid entering one chamber and actuates a secondary valve to admit the liquid to a second chamber and determine the pressure balance between the chambers independently of the absolute pressure level. A membrane transmits the force resulting from the pressure differential between the chambers to the main valve. A bleed screw arrangement regulates the rate of opening and closing of the main valve.

Title: HF medium tension or high tension generator - includes VCO and two regulating circuits which control VCO frequency according to voltage
IPC: H03L7/02
Filed: 1974-12-11
Abstract: For the regulation and safety of A.C. high tension generators, a circuit used has a voltage controlled oscillator (V.C.O.) with two feedback circuits, a transformer (T), a coaxial cable (C.C.) this being represented in the diagram by a capacitance, a self-inductor (LC) and an adder-rectifier (ADD).

Title: Ballistic missiles container mfr. - with material formed welded and premachined and final machining after heat treatment
IPC: B21D51/10
Filed: 1975-05-20
Abstract: The material for the ballistic missile container can be heat treated steel or light alloy, with excellent deformation properties. It is first rolled to shape, or pressed out, using a thickness greater than finally required. The parts are then welded together, using an automatic process. After welding, a premachining operation is carried out, preferably on both sides. Heat treatment is the next operation. Jigs and fixtures are used to prevent undue deformation during stress release and heating is carried out in localised zones. The final step is to finish machine the container, inside and outside, to size.
