Title: High power three-phase rectifier - uses multiphase transformer outputs with thyristor and diode bridges
IPC: H02M7/12
Filed: 1974-01-31
Abstract: The three-phase input transformer of this rectifier has two output windings. One is connected in a simple star format and the other in delta. The star winding (4) supplies, via inductances (15), a mixed rectifier bridge circuit of thyristors and diodes. The delta winding (5) supplies a diode rectifier bridge circuit. Both bridges are connected in series to provide a multiphase rectified output to the load (30). An output level detector (32) compares against a fixed reference (35) using a differential amplifier (34) which controls the thyristors thus regulating the output. Due to the multiphase rectification, only a small filter capacitor is necessary. This circuit is for heavy current rectification and uses economic components without the need for complex filtration.

Patent FR-2236680-A1 (FR)
Title: Vehicle hydrostatic transmission control - uses preset pressure relief valves to avoid excessive braking effect at wheels
IPC: B60T1/08
Filed: 1974-07-10
Abstract: If the engine power of a vehicle which is driven by one or more hydraulic converters or transmissions is cut by the normal removal of the foot from the accelerator pedal, the braking force which is caused by the action of the converter wheels is so large that it can endanger the stability of the vehicle. This condition is avoided by arranging pre-set pressure control valves between the high and low pressure fluid feed and return lines to and from the converter. In the event of an emergency the full effect of the converter braking force is available to the road wheels.

Title: Ventilation shutter actuator - weak link in actuator system is broken when overridden for full closure
IPC: F24F13/15
Filed: 1975-01-24
Abstract: A ventilation shutter system has a set of Z shaped shutter blades (2) which are pivoted by a crank lever system (3) with a set of actuator arms equal in number to the number of blades, and with a common control arm attached to the frame. To swing the blades into a completely closed position, the crank lever system can be swung over fully by an electric, pneumatic or hydraulic servo motor, so as to break a weak link in the control arm so that the latter no longer can reopen the blades. The weak link may be a metal wire or a band or a magnet, or alternatively a spring may be used.

Title: Baling of coils of wire or bundles of steel bars - where binding wire is stretched round bundle and its ends welded together
IPC: B65B27/06
Filed: 1975-04-08
Abstract: Device for binding by welding, esp. the binding of coils of wire or bundles of bars in steelworks, using a machine bed fitted with a binding-wire guide which can completely surround the coil or bundle being bound, the guide possessing a groove for the binding wire; a feeder pushes the wire along the groove and a clamp holds its free end while it is stretched round the bundle, clamped and sheared to length, after which the two clamped ends are welded by electrodes. The novelty is the use of two puller units which draw the crossed ends of the binding wire from a position between the two clamps into a location between the two wleding electrodes. When a twisted joint is made in binding wire, the joint is seldom stronger than 60% of the tensile strength of the binding wire, but a welded joint is much stronger. The invention covers an automatic baling machine for welding binding wires together.

Title: Automatic toilet flushing cistern - uses toilet seat as air chamber to operate air bellows connected to jaws and water release valve
IPC: E03D5/04
Filed: 1975-09-12
Abstract: The automatically flushing cistem for lavatories uses a folding seat forming an air chamber. the chamer is connected to the flushing mechanism by a pipe which enters a second chamber enclosed by a bellows. The bellows are normally held open by a spring which is connected at the bottom to a rigid bar. The bar joins a jaw mechanism which is held closed by a spring around a ball. A person sitting on the flap causes an air pressure to elongate the bellows and maintain the jaws closed. As the person stands, the suction on the bellows open the jaws and sends water into the lavatory bowl through the flap. As the water level falls below the bellows, they expand again and close the water release valve.

Title: Carburettor for automobile IC engine - has spring loaded valve controlling additional air inlet into normal slow running jet for clean combustion
IPC: F02M23/09
Filed: 1976-08-11
Abstract: The carburettor of an internal combustion engine has a conventional slow running jet with an additional air inlet opening into the mixing chamber. A valve with two seats controls the entry of supplementary air and fuel into this chamber. The valve is spring loaded and has a piston subjected to air pressure which acts against the spring. During deceleration when the engine is running quickly with a closed throttle there is no pressure on the piston and the spring moves the valve to reduce admission of fuel. During normal running the pressure on the piston is sufficient to open the valve to admit fuel in the right quantity for clean combustion.
