Title: I.C. engine ignition phase shift signal generation - is shaft speed dependent and controlled by two marking points with specified signal duration
IPC: F02P5/155
Filed: 1974-03-28
Abstract: Periodic actuating signal for motor vehicle combustion engine ignition system is generated by one or more parameters, preferably by the rotational speed of a shaft. The actuating signal is generated with a phase shift which depends on the rotating speed. The ignition system based on this principle uses only electronic components and it is actuated by a mark on the rotating shaft. A vacuum cell may be used in systems whose ignition shift depends on the vacuum. The system generates voltages which are proportional to the time required for given angular displacement. These signals are stored and subsequently second signals are generated, which are linear functions of time. An actuating signal is generated when the first signal voltage is equal to that of the second signal.

Title: Rotating head stapling machine - multiple radial expulsion mechanisms actuated by axle integral cam
IPC: B27F7/28
Filed: 1974-06-10
Abstract: The stapling machine head is a wheel rotating about a fixed axle, with equi-spaced radial multiple expulsion mechanisms (8) actuated by a cam (5) integral with the spindle. The wheel receives wire, cuts and forms staples (11) rotates say 180 deg. then effects expulsion into the workpiece. It constitutes two similar co-axled discs abutting to form radial apertures housing staple carrier expulsion mechanisms: these latter having a rollered end (9) bearing on the cam (4) and, thus, as the wheel rotates sliding diametrically away from the axle as determined by the cam profile to eventually expel the staple into the workpiece.

Title: Liquid gauge for checking tyre pressures - sealed vertical tube with valve ensuring atmospheric pressure returns
IPC: B60S5/04
Filed: 1974-06-25
Abstract: Air pressure in motor vehicle tyres is checked and corrected by a gauge employing liquid such as mercury in a graduated tube. High pressures are measured without recourse to long tubes by enclosing the upper end. A tyre whose air pressure is to be measured is connected to a three way valve permitting compressed air to be applied to the tyre or enable release of air. The tyre is connected via the valve to a tube(7) leading to a container(1) on the garage. Mercury(L) in the container is pushed by air up a vertical column(13, 9, 33) to a height equivalent to air pressure in the tyre. Mercury also passes along channels(11, 14) to push a plunger(8) which in turn pushes a valve(21) upwards so that it seals(22) against a shoulder(19). When measurements are complete, air is released via this valve(21) to maintain atmospheric pressure.

A rigid unit (25) is suspended around the rotation axis for the purpose of carrying reading heads (TA1, TA2, TA3, TB1, TB2, TB3) for the periodic markers. This unit comprises two flanges or rings, placed near the collars or bushes, each ring carrying a fixed circular distribution of reading heads and a spacing sleeve to keep the rings integral with each other.

Title: Boiled egg top remover with pointed blade - has two parts screwed together to hold egg and prevent cracking
IPC: A47G19/28
Filed: 1974-10-15
Abstract: The boiled egg top remover comprises an egg holder which consists of an upper part and a smaller lower part, the latter supporting the egg whilst the upper part has a cutting blade set firmly against the egg by means of the upper part. The upper and lower parts are both provided with threads so that they can be screwed together and hold the egg secure before the top is cut off. The top of the egg protrudes from the opening in the upper part of the holder. Since the egg is held firm by the holder a clean cut can be obtained without danger of the shell cracking.

Title: Backstitch seam sewing process - uses stationary fabric while under loops are formed for lower thread to be drawn through
IPC: D05B81/00
Filed: 1974-11-29
Abstract: In a backstitch sewing process, a sewing machine is used to cross the loops of the upper and lower threads. As the needle penetrates the fabric with the upper thread, forming a loop on the underside of the material, the lower thread is passed through at right angles to the plane of the loop. The stitch is knotted when all the loops have been secured by the lower thread, the fabric remaining stationary while the seam is being executed. The conventional cop for the lower thread is eliminated which, in a conventional sewing machine, has to be changed every 3-4 mins. at high working speeds. The result is less stoppages and less attention to the equipment by the operative.

Title: Operating sprayer bars on agricultural machine - has pressurised liquid to lower bars and spring return hydraulic cylinders (BR310876)
IPC: A01M7/00
Filed: 1975-02-10
Abstract: The liquid to be sprayed is pressurised by a pump (1) feeding into a distributor valve (2) near the driver's seat. Part of the liquid is diverted into a circuit leading to two separate single-acting hydraulic cylinders (4) connected to the sprayer bars (7). These cylinders lower the bars, springs (4) being fitted and used to raise the bars when the hydraulic pressure is lifted by means of the hand-operated distributor valve. This valve also permits either or both bars to be operated. The remainder of the liquid passes to the nozzles. A spring-loaded, non-return valve (3) maintains pressure in the circuit.

Title: Vertical take off and landing aircraft - uses inflatable balloon to provide lift with small control engines
IPC: B64B1/00
Filed: 1975-03-14
Abstract: The vertical take-off aircraft consists of a cabin (6) attached to a shaft (3). A balloon (1) is attached by a cable to the shaft (3) in such a manner that it can incline itself to the force of the wind. Engines (4) are mounted at each end of the shaft and drive propellers. The lift of the balloon balances the weight of the aircraft so that small additional power from the engines will cause the aircraft to climb or descend. The engines (4) are so mounted that they can be aligned to provide a horizontal thrust for level flight. Because only low power is required the propellers can be driven by pedals operated by the pilot.

Title: Sleeve for guiding exit of power cable from electric iron - can be easily adjusted to project either side of iron
Inventor: SCHWOB PIERRE
IPC: D06F75/28
Filed: 1975-06-05
Abstract: An electric iron has a power cable which passes through a guide sleeve attached to the rear of the iron and is connected to a socket of the heating element of the iron. The longitudinal axis of the guide sleeve lies transversely of the longitudinal median plane of the iron, and is provided with symmetrical fixing elements so that it can be easily detached from the iron and positioned to project from one side of the iron or the other without disconnecting the cable. The length of the sleeve is sufficient to allow the cable to be wound around it when not in use. The iron can be easily adapted so that the power cable exits from one side of the iron or the other, thereby making the iron simpler to use.
Patent FR-2316509-A1 (FR)
Title: Safety valve for medical perfusion system - protects patient from air bubbles in fluid and from over pressure
IPC: A61M5/168
Filed: 1975-06-30
Abstract: The safety valve is used with a perfusion system in which fluid from a reservoir is delivered by a peristaltic pump to the syringe which is inserted in the patient. The safety valve consists of a slab of glass reinforced nylon with three holes in its edges for connecting to the pipes. These holes communicate with holes perpendicular to the main surface which is covered with a membrane of silicon rubber. The membrane ensures laminar flow between the inlet and outlet so that no air bubbles can reach the outlet. The column of fluid in the tube acts as a pressure limiting devide and also allows air bubbles to return to the reservoir.

Title: Sanitary water flushing appts - has level switch regulating electrically operated valves filling water tank
IPC: A61G9/02
Filed: 1975-12-18
Abstract: The apparatus is for cleaning bedpans etc, having a water tank above the washing chamber with a pump at its outlet supplying hot and cold water via nozzles for cleaning the items inserted in the chamber. One or more electrically-operated valves (10) are provided for filling the tank (7), and their opening periods are limited by a level switch (12). The pump (6), drawing in water from the tank outlet (8), delivers to the nozzles (4) via a washing pipe (5). This extends upwards from the pump in a loop to the maximum level of water in the tank, and to its highest point an air vent pipe (9) is connected. This in turn discharges into the tank above the maximum water level. There can be a metering device upstream of the nozzles, and which can be brought in and out of action, delivering chemical disinfectant.
