Title: Hybrid electric and heat engine propulsion for vehicle - uses electric drive and heat engine drive coupled by variable dia. pulleys and clutch
Inventor: SAGEAU ANDRE
IPC: B60K6/48
Filed: 1980-11-25
Abstract: The hybrid electric/heat engine propelled vehicle has a battery, an electric motor, and mechanical coupling to the road wheels as one form of propulsion, and a heat engine with mechanical coupling to the road wheels as a second form. Provision is also made for both electrical and heat engine systems to operate simultaneously. The electric drive coupling is by a toothed belt and pulley transmission with pulleys whose diameter, under centrifugal force, varies with speed of rotation. The mechanical drive coupling uses toothed pulleys and a toothed belt with a clutch mechanism coupled to the heat engine. The speed regulation of both electric and heat engine drives is controlled from a single speed control pedal, and the clutch engages the heat engine when the speed control pedal has reached a preset point in its travel.

Title: Non-inverting variable ratio DC=DC switching regulator - uses series switch driving an LC circuit to step up input voltage and shunt switch to lower output voltage
Inventor: DASSONVILLE JACQUES
IPC: H02M3/158
Filed: 1980-12-29
Abstract: The regulator provides a variable DC to DC conversion ratio able to provide output voltages above, equal to, or below the DC input voltage. The regulator uses a series switching transistor driving a series inductor (L1) and shunt output capacitor (C2) to step up the input voltage, then a shunt switching transistor across the output to lower the DC voltage. By variation of transistor ON/OFF time ratios the voltage at the output terminals is variable. The DC supply (SC) is coupled to a series pass transistor (S2) which feeds a series inductor (L1). A free wheel diode (D2) is connected between their junction and ground. A shunt connected switching transistor (S1) shorts the inductor output to ground when the output is to be reduced. Control circuits (3,4) determine the conduction internal of both transistors and ensures synchronisation between them.

Title: IC engine fuel injection pump - has muff with internal surface defining shape such that axial movement varies fuel amount supplied through pump outlet
Inventor: MOWBRAY DORIAN FARRAR
IPC: F02D1/02
Filed: 1981-02-26
Abstract: The appts. includes a body in which is journalled a rotary distributor member having a transverse bore which accommodates a pumping plunger movable inwardly by cam lobes on a surrounding cam ring. Fuel displaced by the plunger during inward movement by the cam can flow to an outlet by way of a passage and an outlet port providing a passage extending to the periphery of the distributor member is covered by a muff. The interior surface of the muff has wedge shaped portions which obturate the port or ports at the end of the passage. This causes the fuel to be delivered to the outlet and the angular and axial settings of the muff can be varied by actuators. Fuel enters the bore from a space surrounding the distributor member through the passage when the plunger performs its outward suction stroke. A pair of transducers is used to provide signals indicating the axial and angular settings of the muff.

Title: Self adjusting ultrasonic intruder alarm - uses comparison between successive echo times to determine presence of intruder and actuate alarm
Inventor: RICHARD ANDRE
IPC: G08B13/16
Filed: 1981-06-22
Abstract: The system uses ultrasound with a transmitter and a receiver both connected to the same transducer. The transmitter produces pulses for transmission, and subsequently echoes are received by the receiver tuned to the same operating frequency. The receiver is connected to a signalling circuit via an echo pulse processing circuit. In this circuit the received echoes pass through a wave shaping device and then their time of arrival is compared with the originally transmitted signal. The interval between the appearance of two successive echo signals is memorised and another signal, which is related to a disparity in at least one interval, is produced. A sequential logic unit receives these signals and feeds an alarm signalling arrangement.

Abstract: The machine is intended mainly for producing chemical fibres from solutions by the wet-spinning process, especially for producing textile viscose threads and for producing viscose staple fibre. The machine contains, arranged in the production line: a wet-spinning unit for threads (3), discs (1, 2) for the transport of the latter and a device for removing the gas/air mixture from the spinning zone of the threads (3). This device includes a perforated gas-removal tube (9) which extends along the transport path of the threads (3) from the wet-spinning unit to a receiving device, the perforations (12) of the tube (9) confronting the transported threads (3). The tube (9) is connected to a suction-ventilation system by means of two collecting lines (6, 7) which are located in the upper and lower parts of the spinning machine. In the straight portions of the transport path of the threads (3), the tube (9) is provided with guide plates for the sucked-off air stream, which are mounted on the tube (9) in the zone of the perforations of the latter. The guide plates can be designed in the form of perforated gutters (15) which surround the transported threads (3). In one of the embodiments, the perforations (16) on each gutter (15) are located in two rows in the peripheral parts of the gutter. At the same time, there adjoins each row of perforations (16) from the outside an associated gas-removal tube (17), through which the air is removed from the transport zone of the threads (3).

Title: Pre-emphasis sampling mode filter for SECAM TV colour coder - operates on chrominance subcarrier signal by digital sampling to achieve specified transfer function
Inventor: MORAILLON JEAN YVES
IPC: H03H17/06
Filed: 1981-09-29
Abstract: The filter has an 'inverted bell' response, intended for use with the chrominance signal of a SECAM colour television encoder. The filter operates by sampling, preferable digitally, and has a transfer function of the form (G(z)=a+bz power -1+cz power -2. The sampling frequency is four times the frequency of the chrominance sub-carrier in the PAL colour television system. The filter includes a first delay element (15) whose input is connected to the first inputs (20,18) of two adders (21,17) - one via a further delay line (19). The first adder output is fed directly to one input of a subtractor (28), while the second adder output passes via further processing circuitry to the second subtractor input. The subtractor output then forms the final output of the filter circuit.
