Title: Fuel injection system
IPC: F02D41/12
Filed: 1970-09-07
Abstract: 1351614 Fuel injection systems JOSEPH LUCAS (INDUSTRIES) Ltd 7 Sept 1971 [7 Sept 1970 10 Sept 1970 42812/70 and 43450/70 Heading G1N In an I. C. engine fuel injection control system of the type which provides injection valve energizing pulses in synchronism with engine rotational speed and having a duration dependent on at least one operating parameter, a circuit 30 is provided to inhibit the energizing pulses when an engine over-run condition is sensed, e.g. when the throttle is closed, engine speed exceeds a predetermined value, the fuel supply being restored when the engine speed falls to a second predetermined value lower than the first predetermined value but above engine idling speed. As shown, pulses from an engine driven trigger 18 are applied to a monostable multivibrator 36 via a shaper 32, the output pulses of 36 being applied to two ramp circuits Rl, C1 and R2, C2 and threshold circuits 40, 42 having different response levels. A switch 52, connected to the throttle, is provided between a commonoutput point 46 of circuits 40, 42 and a threshold circuit 50. If the engine speed is above a value, set by the threshold value of circuit 42, and the switch is closed, the circuit 50 provides an output to inhibit the energizing pulses from monostable multi-vibrators 14 or amplifiers 16. Not until the engine speed falls to the second predetermined value, set by circuit 40, or the switch 52 is opened, are the energizing pulses restored. In a modification, an integrator could provide a D. C. voltage level from the trigger pulses, and the two threshold circuits can have their outputs combined with that of the switch in a suitable gating circuit with a "hold" facility. In an alternative, Fig.2 (not shown), the trigger pulses from 18 are applied to an integrator in the form of a diode pump to provide a voltage which is applied, via the throttle controlled switch to a threshold circuit in the form of a biased emitter transistor having a feedback circuit connected to the emitter to adjust the voltage level to the second value when the transistor produces an output to inhibit the energizing pulses. In modifications, the diode pump could be replaced by a monostable circuit feeding an RC integrator, the emitter biased transistor could be replaced by a Schmitt trigger, the switch could be positioned differently or replaced by a manifold pressure transducer connected to a differentiator.

Abstract: 1,142,975. Ripple control transmitters; generating oscillations. ELECTROMETRE S.A. 22 Sept., 1967 [30 Sept., 1966], No. 43195/67. Headings H3B and H4R. In a ripple control system for signalling the values of consumption meters over an electric supply network, a capacitor 3, which is charged through diode 5 to the peak value of the supply voltage, is discharged through a coil 2 by the semi-conductor controlled rectifier when a control pulse, having a precisely defined phase relative the supply voltage, is applied to the gate electrode 6 of the S.C.R. from the control circuit 9. In order to maintain the conduction of the S.C.R. irrespective of the length of the control pulse, feedback is provided from the coil 2 to the gate electrode via coil 13, the feedback maintaining conduction until the damped oscillation produced by the discharge through coil 2 drops below a predetermined value. In an alternative arrangement two S.C.R.'s are connected in series, with feedback via respective feedback windings, in order to reduce the voltage rating required of the S.C.R.'s, Fig. 2 (not shown).

Filed: 1960-12-28
Abstract: 975,061. Artificial respiration apparatus. CHIRANA PRAHA NARODNI PODNIK. Dec. 28, 1960 [Jan. 28, 1960], No. 44396/60. Heading A5T. Automatic resuscitation apparatus comprises an injector 7 and an ejector 6 which are alternately operated for supplying gas to and exhausting gas from lungs, respectively, the injector and the ejector being controlled by a diaphragm 2 which moves in response to pressures in a chamber 26, two unidirectional valves 28, 29 between the chamber and a space 25 in communication with the lungs, the valves controlling the inspiration overpressure and the expiration underpressure, respectively, and an adjustable exhaust orifice for gas withdrawn from the lungs by the ejector for regulating the expiration time independently of the inspiration time. For inhalation, compressed gas is supplied through a tube 19 and an adjustable valve 9 opened by the diaphragm to an injector 7 where it entrains atmospheric air, the mixture then passing through a second valve 11 opened by the diaphragm into the space 25 which communicates with the lungs through a tube 5. The rise in pressure in the space 25 is communicated to the diaphragm chamber 26 through the valve 29 and a needle valve 15. At a predetermined maximum pressure the diaphragm moves to operate a switch over mechanism 3, 3a-3e which permits closure of the valves 9, 11 on each side of the injector and causes opening of adjustable supply and exhaust valves 8, 10 associated with the ejector 6. The ejector then operates to exhaust gas from the space 25 through the exhaust valve 10 and a port carrying an adjustable orifice plate (not shown). The resulting fall in pressure in the space 25 is communicated to the diaphragm chamber 26 through the valves 28 and a second needle valve 14 and, on reaching a predetermined minimum, causes the diaphragm to move to switch over the mechanism controlling the valves 8, 9, 10, 11 to their position for the inhalation phase. If the pressure in the space 25 becomes too great, the exhaust valve 10 opens to vent gas to atmosphere through a flap valve 16. If the pressure in the space 25 becomes too low, atmospheric air is supplied through valves 11 and 17.

Abstract: 1330179 Moving and changing displays F T WINSLOW and R B STANISH 21 Sept 1970 [13 Oct 1969] 44899/70 Heading G5C A display apparatus has a design panel having a design thereon and a liquid flow conduit adjacent the panel and extending parallel to it, the conduit and design being mutually aligned in the line of view of a spectator and being so arranged that, as liquid is drained from the conduit, the design progressively becomes visible to or changes colour as viewed by the spectator, each of a plurality of separate design details of different shapes and sizes being wholly aligned with a respective single portion of the length of the conduit which is wider than the portions leading into and out from it. In one embodiment, Figs. 1, 2, the design panel 14 is largely opaque but with light passing portions 16, 18, 20, 22 in the form of the design and the conduit 26 with its widened portions e.g. 76, 78 is formed from two sealed face-to-face sheets of transparent plastics material having moulded channels in one or both. The panel 46 formed by these sheets is situated behind the design panel 14 and a lamp 64 is located behind the panel 46. Coloured fluid is pumped into the conduits by a bellows pump 50 and lamp 64 is unlit. When the pump is completely compressed, switch 86 is operated to light the lamp, the pump expands and fluid is drained from the system and the air/fluid interface appears to "draw", in light, the design, after which the light goes out and the cycle repeats. The system contains an air reservoir 28 to collect undesirable air bubbles, a liquid reservoir 30 and orifices 34-40 with interconnecting pipes 42, 44 to enable variation in the direction of fluid flow. For effect, bubbles may be purposely introduced into the system by reducing the amount of liquid or changing the timing of the cycle. The liquid may be opaque, translucent or coloured and may contain fluorescent material to be illuminated by an ultra-violet lamp. The opaque parts of the panel 14 may also be coated in fluorescent material. Two or more of the units may be used, one overlying another (Fig. 3, not shown), and a number of alternative modes of operation are described where more than one bellows pump are used. In another embodiment (no drawing) the design panel is completely opaque and the conduit is placed in front of it as viewed by the spectactor. Preferably, the fluid is the same colour as the background of the design. A plurality of the display units may be attached to the periphery of a cylinder rotating about a horizontal axis whereby the action of gravity produces the necessary filling and draining of the conduits.
