Title: Progressive gas flow rate control valve - has orifice connection between chambers and sprung outlet control piston
IPC: F01D15/06
Filed: 1974-03-19
Abstract: The flow control is achieved by sensing the pressure difference between supply and discharge and using it to control the position of the discharge valve. The valve body (2) is connected (1) to an air motor discharge port, the air flows into a chamber (2a) and thence via a small orifice (3) into another chamber (4). One end of the second chamber is closed by a spring (8) loaded piston (7) and the other carries an adjustable end stop (10) with a passage (5) to atmosphere. When pressure in the chamber (2a) rises (high motor speed) the piston moves progressively against the spring pressure to seal off the orifice (3) and reduce the flow rate.

Patent FR-2297369-A1 (FR)
Title: Gate valve with two valve plates - has wedges forcing plates together away from seats against spring force
IPC: F16K3/18
Filed: 1975-01-13
Abstract: A gate valve is formed from two parallel plates which seal on satellite seats of two tubes and slide transversely to the tubes under the action of a shaft. Between the valve plates is a compression spring which ensures a good seal when the valve is closed. The drive shaft does not act directly on the valve plates but through sliding wedges on each side of the centre line. The wedges are connected to each other via a ring surrounding the spring and to the drive shaft. As the drive shaft is withdrawn, these wedges force the valve plates together against the pressure of the spring. This action "cracks" the downstream seal and eventually equalises the fluid pressure on either side of that valve plate. Vent holes in the upstream valve plate equalise fluid pressure on that valve plate when closed and thus allow it to seat properly.

Title: Sand injector for foundry cores - has faster workcycle and is accessible for cleaning
IPC: B22C15/24
Filed: 1975-05-21
Abstract: Sand supplied to a reservoir is injected into the mould using a jet of air from a compressed air container. The container is situated above the mould and has air passages in its bottom and directed downwards. A lower connection into which air passages open out, is co-axially situated below the container and directed downwards. Guide elements in the connection close and open the air passages when desired and guide the jet of air. A reservoir situated above both the container and the connection is movable between a position below a sand hopper and a position co-axial with the container and the mould. The upper opening of the reservoir is fluid-tightly connected to the connection in order to receive the air jet. Fluid-tightness between the connection and the reservoir and between the reservoir and the mould is assured by devices exerting coaxial pressure. These also resist the counter pressure of the compressed air during blowing. Direct communication between the air container and the sand reservoir is achieved. Pressure can be reduced since the air passages are less tortuous.

Title: Motor vehicle bumper has springy central strip - held elastically in a rigid profiled steel bar
Inventor: BASILLE MICHEL
IPC: B60R19/18
Filed: 1975-07-30
Abstract: The rigid part of the bumper is of steel in a widened W section, i.e., a pair of V sections joined at the top by a flat bar. The springy strip is of plastic (polyamide, PVC or rubber) and is of U section; it fits in the widened central section of the W. The U section is held open by a spring strip (of plastic or steel) between the ends of the arms of the U. This makes it fill all the available space between the V's of the W, so that normally it rests at the outer end, where it is held in place by its rims catching against clips put round these V's. Impact or pressure on the central section makes the U close up, narrowing its open end: it slides down into the W, to return when the constraint is removed.

Title: Granular minerals continuous purificn. - by subjecting a mixt. of water and a mineral to ultra-sonic waves
IPC: B03B13/00
Filed: 1976-01-22
Abstract: Minerals with impurities surrounding the grains are fed continuously into a closed container into which water is introduced at the bottom through a perforated pipe, and then flows upwards through the container. Ultra-sonic waves are transmitted through the mineral-water mixt. by transducer immersed in the mixt. mounted vertically or on spiral formation on a rotating shaft set on the axis of the container. The transducer can also be in the form of a single vertical cylindrical crown. Ultra-sonic waves which have a power in the order of 1 watt/cm2 pass horizontally through the mixt. Pure mineral is extd. at the bottom of the container and the water overflows into a channel near the top of the container from where it is pumped away. The water is de-gassed by continuously evacuating an air space above the level of the mineral/water mixt. at the top of the container. Alternatively the water can be de-gassed before it is pumped to the container. The process is used in the continuous purificn. of granular minerals, esp. quartz sands, and is purely physical, as opposed to the messy chemical processes generally used.

Title: Ripple suppression circuit for TV receiver - uses rectified flyback pulses to control ripple-proportional correction current
IPC: H04N3/237
Filed: 1976-02-18
Abstract: The ripple suppression circuit is for television receivers and obtains line flyback pulses from a line transformer and passes them over a rectifier circuit to give a control signal for a second correction current which is proportional to the ripple. The current in the line transformer is shaped by a transductor whose control winding is supplied with a parabolic first correction current having a frequency which is the same as that of the field, and a second correction current which is proportional to the ripple voltage. The configuration of the ripple suppression circuit avoids a phase shift between the controlling and the controlled signals.
