Title: Image distortion corrector for scintillation camera - where computer determines coordinates for each scintillation pt. and feeds memory store supplying signals to image corrector
Inventor: ROZIERE GUY
IPC: G01T1/164
Filed: 1981-01-13
Abstract: A photocathode receives light from a scintillator, and provides an image on a cathode ray screen (I). Screen (I) is monitored by photomultiplier tubes connected to a computer, which determines the XY co-ordinates of successive points (n, n+1...) forming an image. The computer output for one point (n) is fed to a memory store, so the computer is emptied and can start to process the next point (n+1). While the computer is processing point (n+1), the memory store delivers the data obtd. for point (n) to an image distortion corrector, the output of which is fed to a visual display screen (II). The successive signals do not interfere with each other.

Title: Coupling bolt for tractor brake pedals - has angled end for foot operation to separate coupling via ratchet
IPC: B60T7/06
Filed: 1981-02-05
Abstract: The coupling bolt for linking the two brake pedals of a tractor has a spring mounted assembly which pulls into the coupled position and a foot operated lever end (9) to pull the coupling apart. A ratchet (13,14) under one pedal secures the bolt in the uncoupled position. The coupling is operated by the foot of the driver, with the bolt assembly under the one pedal (8). When the driver releases the ratchet, by pressing down on the angled end (9) the spring drives the bolt to engage a coupling hole in the other pedal (1). The coupling and decoupling action is performed with the foot and requires no visual aid.

Title: Positive-action key-pad for printed circuit boards - works by flexing action of elastic conducting disc and has contacts enclosed by flexible membrane
Inventor: BEAUVAIS HUGUES PELLERIN DE
IPC: H01H13/02
Filed: 1981-04-02
Abstract: The button mechanism is contained within an insulating housing. Four contact pins protrude through the base of the housing. They have rounded heads and are disposed at the three points and at the centre of an equilateral triangle. Two circular rims surround the pin leads and provide an anchorage for a flexible membrane. An elastic conducting dome-shaped disc fits over the outer contacts so that it touches all three in its rest position. When the membrane is depressed, the pads on its underside push the dome so that its shape is deformed downwards, making a convex depression which makes electrical contact with the central pin which constitutes the closing of the switch. The button head contains a cavity in which a source of illumination is housed. The electrical connections are arranged to bring this light on when the button is depressed. The downward involvement of the button is communicated to the membrane via a conical protuberance on the upper side of the membrane.

Title: Machine folding paper sheet - uses two parallel inversely rotating rollers, one of which effects suction grip and pushes loose fold into roller gap
IPC: B65H45/14
Filed: 1981-07-01
Abstract: The device folds sheets (2a) of paper e.g. fed by a conveyor (1) or similar to two nominally offset rollers (4,6) rotating in opposite directions (F1,F2) being used to produce circular letters etc. The gap between the rollers forms a pinching zone (7), the leading roller (4) contacting a sheet along a line (5) normal to a tangent and upstream of the pinching zone. In addition the leading roller has suction windows (9) which are selectively connected (50,51,52) to a vacuum source, the suction phase lasting while the relevant window moves between the contact line (5) and the pinching zone. The trailing part of the sheet is gripped, the combined affects of continuing roller motion and a deflector stop (62) pushing a loose fold into the pinching zone to be finished by a proud segment (8) of the trailing roller (6).

Title: Power generator for ionic conduction lamp - provides power at high impedance during starting and power at lower impedance during operation of lamp
Inventor: SHERMAN ELI HENRY
IPC: H05B41/04
Filed: 1981-08-24
Abstract: The appts. generates power with a relatively high voltage and impedance so as to match the load before starting and generates power of a lower voltage and impedance so as to match the load during the energising and operation of the load. The appts. may have a coil, and a transistor, to develop a voltage over the coil. The coil may be coupled to the lamp through a capacitor or stray capacitance between the lamp and a coil. A tap intermediate the ends of the coil may be coupled to the load. The capacitor is effectively electrically inoperable and out of the circuit after starting of the load. The capacitor is located such that the full voltage developed across the coil is delivered to the load during starting, but after starting and during operation only a portion of the voltage developed between one terminal and the tap of the coil is used to drive the load. The generator eliminates the need of a conventional ballast and starting mechanism. In this way, the lamp can be maintained with energy savings. Further energy savings are achieved by generating current and voltage pulses for operating the lamp where the voltage pulses have a greater decay rate to a zero level than the current pulses which have a more gradual decay.

Title: Hydraulically operated rotary motor - has triangular rotors within link chain in outer pressure casing
Inventor: GAUDEL JACQUES
IPC: F01C1/30
Filed: 1982-02-16
Abstract: The motor has a sealed outer casing (1) in which are housed three triangular rotors (7-9) running freely on their respective shafts (12-14). A six link chain (2) is fitted over the rotors. Rotation of the rotor chain assembly brings it successively into stable and unstable positions. The casing is divided into two compartments (A,B) having a water-tight partition. The inner compartment (B) is connected to atmosphere. When the rotor is in an unstable position, fluid, introduced under pressure will impart an equalising pressure around the chain and cause it to rotate into a stable position.

Title: Vapours, melts, pastes solidification - in bed of solidified material with stirring mechanism inside cooled tank
Inventor: LIST HEINZ
IPC: B01J2/10
Filed: 1982-04-30
Abstract: Solidification of vapours, liq. melts or pastes by cooling to a granular free-running consistency, e.g. in the prodn. of TDI (toluylene diisocyanate), is based on feeding the charge into a bed of already solidified material. The heat of solidification is transferred to the cooled walls of the bed container by a stirring mechanism. This prevents the formation of clods. The large cooling surface results in less bulky equipment and reduces the power consumption.
