Title: Correction cct. for engine fuel injection system - varies duration of injection time according to exhaust oxygen content
IPC: F02D41/24
Filed: 1974-03-06
Abstract: A basic fuel injection control circuit consists of three electronic counters which count N1, N2 and N3 pulses respectively. The binary word M is applied to the first computer (1). The pulses indicated by H are counted successively on the counters (1) and (2). When the counters (1) and (2) have completed counting, a pulse (5) is supplied to the counter (3) which consists of two elements (6) and (7) and the signal to terminate the injection period is delivered through the gate (4). This signal can be modified by installing a correction circuit between the terminals (K and K'). This correction circuit can modify the injection time according to any additional variable such as exhaust oxygen content.

Title: Multiple filled sack handling belt - has auxiliary belt sliding at one end on main portion and lockable
IPC: B66C1/18
Filed: 1975-05-07
Abstract: A lifting belt for the handling and storage of material in sacks, comprises a main belt (2) forming a ring, inside which is an auxiliary gripping belt (4). One end of the auxiliary belt is fixed to the main one, while the other (5) slides along it, being secured to it by a locking device functioning under traction at right angles to the main belt. The sliding joint can be in the form of a buckle with automatic jaw. The buckle can be so arranged as to allow the main belt to slide freely through it as long as no lateral traction is exerted on the auxiliary belt. It locks when this occurs, due to the sacks in the stack tending to spread apart on setting down.

Title: Open end spinning device has guide disc located in rotor mouth - the disc periphery curving away from rotor bottom to decelerate fibres
IPC: D01H4/08
Filed: 1975-10-22
Abstract: An open end spinning device includes a spinning rotor in the mouth of which is positioned a fibre guide disc whose outer pref. frusto-conical face forms with a surface of a surrounding housing an annular channel along which fibres are fed onto the fibre collecting surface of the spinning rotor. The peripheral edge of the fibre guide disc is curved in a direction away from the bottom wall of the spinning rotor to de-celebrate the fibres before they pass from the channel onto the fibre collecting surface of the spinning rotor. Reducing the speed of the fibres passing in an air flow along the channel causes them to be deposited on the fibre collecting surface in a more orderly fashion, resulting in a more uniform yarn.

Title: Financial profit loss evaluation simulator - uses loaded beam which can oscillate to balance position between two loaded ovoid discs
IPC: G06G3/10
Filed: 1975-10-28
Abstract: The financial system simulator consists of an avoid wheel (1) formed from two identical flat parallel discs (2). The discs separated distance pieces (3), are cut out according to a continuous geometric line defining a solid part which narrows in the upper curve of the wheel and enlarges progressively on the sides towards the lower part of the wheel and then climbs again like a cone. It becomes thinner until approximately the middle of the wheels central zone. The centre of gravity of this central zone is situated between the summit and the base of the cone. The system uses a balance which is designed to hold charges. The balance can oscillate around a central axis formed in the ends of the core and between the spare between the discs. The charges which simulate the financial influencing factors make the balance and wheel swing to an equilibrium position corresponding to an analysis of the overall financial situation.

Title: Practice land mine for training exercises - has ignition charge in gas producing powder which ignites fuse of smoke producing powder
IPC: F42B8/28
Filed: 1976-02-25
Abstract: The practice land mine is used in training exercises and can simulate detonation when the detonator is fired by pressure exerted on it. This simulated detonation is in the form of a visible smoke signal issuing from vents (7, 8) in the mine casing. The detonator fires an ignition charge (20) embedded in a gas producing powder (12). The gas pressure generated opens a valve (13) against a seal (19) and the escaping gas loosens the earth above the mine. A fuse (28), ignited by the gas powder, ignites a lower charge (25) of smoke producing powder. This escapes by following the gas and provides the visible signal.
Patent FR-2304549-A1 (FR)
Title: Friction belt drive for belt conveyor - has vacuum between drive and conveyor belt to prevent slipping
IPC: B65G23/36
Filed: 1976-03-10
Abstract: The drive unit for a belt conveyor (1) consists of a belt (9) located on two pulleys (5, 6) which are located between the upper and lower belt section of the conveyor (7). Support rollers (13) below the contact area of drive and conveyor belts produce the required contact pressure to avoid slip between the two belts. The drive belt (9) has longitudinal grooves on its outside which are in close contact with air nozzles (15, 16) above each belt drum. When the air in the belt grooves is evacuated through the nozzles, a vacuum is created which is increases the contact pressure between the belts, preventing belt slip.

Title: Shotgun cartridges automatic packing machine - includes inverter and stacking piston which descends to pack plastics bags
IPC: B65B19/34
Filed: 1976-08-23
Abstract: The machine is used for the orderly packing of cylindrical objects, such as shotgun cartridges, in a supple plastics bag. The machine has an inverter which arranges the objects head to tail by tipping the object about one axis or another under its own weight. The objects are then stacked by a piston and lever arrangement. A bar (F) is attached to a spring loaded (G) lever (I) which is in turn attached to a catch (H) supporting a piston (B). It is moved across by the influx of objects (A). When one row is full the catch disengages and the piston falls by one layer depth. When the required amt. is stacked on the piston it can be raised into a plastic bag held open by two spacers. The bag is then sealed by hand.
