Title: Fuel economizing apparatus for vehicles
IPC: F02D41/14
Filed: 1974-11-27
Abstract: 1462216 Automatic control of vehicle speed and I C engine fuel supply NIPPONDENSO CO Ltd and TOYOTA JIDOSHA KOGYO KK 27 Nov 1974 [7 May 1974] 51417/74 Headings G3N and G3R [Also in Division F1] A control system for an I.C. engine driven vehicle includes a first constant speed control for responding to the difference between a demand signal and an actual speed signal to vary the opening of the throttle valve in a direction to reduce the speed error, second control means responding to an engine operating condition, e.g. manifold pressure, to supply a quantity of fuel to the engine and a correction system responsive to the speed error signal and to the rate of variation of fuel quantity to modify the amount of fuel supplied when the constant speed control is operative. Fig. 2 shows a constant speed control system A which includes a discriminator 5 for comparing the outputs of a speed setting arrangement 3 and an actual speed detector 4 to produce an error signal which is used to operate throttle valve 2 through a mechanism 7. The actual speed is derived from pulses from the engine contact braker which are integrated to provide a voltage representing actual engine speed. The mixture control B includes a manifold pressure sensor whose output signal is used to adjust the effective stroke of fuel injection pump 60, see Fig. 4, by altering the position of stop 73 on plate 65 and thus the quantity of fuel injected. When the automatic constant speed control is operative the engine fuel and ignition settings are changed to run under optimum conditions by advancing the ignition timing by a fixed amount and modifying the control signal to the fuel injection system to weaken the mixture. The ignition advance is obtained by using a second set of contacts in the contact breaker which are angularly spaced from the first set and the mixture is changed by multiplying the fuel signal by a factor derived from the speed error signal Vo and the differential of the injector control arm position signal Vp. A counter is used in the correction circuitry so that the fuel supplied is altered in step fashion to the reduced setting. A mechanical speed control arrangement also is described, Fig. 9 (not shown), where a weight type governor is locked electromagnetically to an hydraulic flapper valve at the desired speed setting and thereafter the valve alters the pressure in a cylinder connected in the throttle linkage to change the throttle valve position.

Abstract: 1292340 Automatic phase control ORION RADIO ES VILLAMOSSAGI VALLALAT 21 Oct 1969 [21 Oct 1968] 51597/69 Heading H3A A system for synchronizing a local clock signal with a received data signal of the type in which the synchronization is effected by controlling a divider which produces the local clock is characterized in that the output signal from the final stage of the divider is divided into a " discrimination" period and a variable length "intervention" period, the length of the latter being adjusted whenever the phase error detected during the discrimination period exceeds a predetermined value and the sense of the adjustment depending on the sign of the phase error. As described with reference to Fig. 2, pulses from oscillator 1 are fed through divide-by-two stage 2, divide-by-five stage 3, and final divide-by-two stage 4 to produce pulses at the required clock rate, and the output from the stage 4 is divided into the. two required periods by gating it with the output from stage 3 in comparator 5. If the phase difference between the input signal 9 and that from the stage 4 is such that a transition of the input signal occurs during the discrimination period, bi-stable 35 is set, thus enabling the logic circuit 31 . . . 34 to produce appropriate signals on lines 19, 20 to change the division factor of stage 2 so that the chain divides by 19 or 21 as required instead of 20.

A mixture of fuel and water enters housing 38 at 32 and the fuel flows outwards through pervious hydrophobic concentric screens 50 to 64 which progressively hold back the water in steps as shown, and the fuel and water leave by respective outlets comprising selfstarting siphons which start at levels F 1 , W 1  and stop at levels F 2 , W 2 . The water siphon comprises concentric tubes 72, 74, the fuel siphon comprises an annular space 88 in the housing wall and three circumferentially spaced outlet tubes 94. The screens may be wire coated with P.T.F.E., whose aperture sizes (given) may decrease stepwise outwardly, either by varying the screen mesh size, the coating thickness or the wire diameter, and all or alternate screens may be pleated (Fig. 4, not shown). The alternate pleated screens may be non-hydrophobic and merely reduce splashing Alternatively the outer screens could comprise helically wound P.T.F.E. ribbon type elements. Specification 1,045,347.

In Fig. 2 water enters tank 6 through stand pipe 11, and a tuyere plate 12 distributes the water over contact material 10 so that the water absorbs ozone in air delivered through line 13, exhaust gas leaving at line 14 through ventilator 15 which keeps water level 16 constant. The water passes through bed 8 comprising said mixture, tuyere plate 7 and leaves via spigot 18. The filter may be flushed with water through 18 and up through the bed 8, and sludge is discharged through central pipe 17.

Title: Process for refuelling an electrical energy storage device

Filed: 1972-11-14
Abstract: 1416024 Physically refueling an electrical storage device OMF CALIFORNIA Inc 14 Nov 1972 [18 Nov 1971] 52622/72 Heading H1B An electrical energy storage device of the type utilizing a halogen hydrate, an oxidizable metal and a circulating aqueous electrolyte containing a dissolved metal halide as described in Specification 1,339,060 is recharged or refueled by periodically as necessary physically replenishing the oxidizable metal and the halogen hydrate which are progressively consumed during discharge of the device and by withdrawing an amount of the electrolyte to maintain the volume thereof within a preselected range. Preferably the cell utilizes chlorine hydrate, zinc and an aqueous electrolyte of zinc chloride in which the chlorine hydrate is disposed. The hydrate may be replenished by replacing a storage reservoir forming part of the electrolyte circulating system in which prior to discharge a quantity of chlorine hydrate is disposed with a second storage reservoir charged with chlorine hydrate. By this replacement the required adjustment in the volume of the zinc chloride electrolyte is also effected. Alternatively, chlorine hydrate in particulate form suspended in a slurry or as solid pellets or blocks may be inserted into the storage reservoir. In this event excess electrolyte must be separately withdrawn from the system. The zinc may be replaced by (a) replacing the cell of the system by a second, replenished cell, or (b) replacing only the zinc-containing negative electrode of the cell, or (c) passing electrolyte containing a slurry of zinc through porous chambers in the negative electrode whereby the zinc is filtered out by being retained in the chambers. When a number of these cells are used to propel a motor vehicle, for example, a number of roadside stations at which replenishment of the necessary cell components takes place are provided. At such regional or central stations the removed spent components are recharged by appropriately passing a D.C. current through them and subsequently they then form replacement units. An extensive list of elements suitable for the negative electrode metal are given.
