Title: Fuel injection systems for diesel engines
IPC: F02D41/38
Filed: 1973-10-06
Abstract: 1481171 Electric protective systems CAV Ltd 26 Sept 1974 [6 Oct 1973] 46792/73 Heading H2K Signals from an engine speed responsive transducer, an actuator position responsive transducer and a demand representing means (accelerator pedal) are fed to a governor which controls the actuator supply circuit for controlling a fuel injection pump of a diesel engine and relay means responsive to the current in the actuator supply circuit interrupts the circuit when the current therein exceeds a predetermined value. The governor (Fig. 1, not shown) provides a signal to the base of a transistor 43 and the current in the actuator coil 14 is controlled thereby. If excessive current flows in the series circuit of a resistor 44, coil 14 and transistor 43, a transistor 47 carries increased current and a Zener diode 51 breaks down to make a transistor 39 conduct and deprive a transistor 37 of its base drive and thus the main circuit through a relay coil 35 is interrupted so that relay contacts 34 open to disconnect the actuator coil circuit 44, 14, 43. Whilst a manual switch 36 remains closed the base drive of transistor 39 is sufficiently maintained by a current through coil 35 and resistor 54 so that transistor 37 does not conduct.

Title: Improvements in and relating to methods of electrolessly plating nickle-iron alloys
IPC: H01F10/10
Filed: 1962-12-18
Abstract: <PICT:1023953/C6-C7/1> Nickel-iron alloy is electrolessly deposited on a substrate e.g. glass, plastic or ceramic by cleaning the substrate, e.g. with NaOH, HF or NH4F solution, preparing an acid Ni-Fe hypophosphite plating solution wherein the ratio of Ni to Fe ions is less than 1 and the pH value is 4, adding palladium ions to the solution, then adding a base to increase the pH value to 9.2, inserting the cleaned substrate into the solution and removing therefrom when the desired thickness of coating has been deposited. The plating solution may be prepared at room temperature by dissolving 0.5 g. sodium hypophosphite, 1.5 g. sodium potassium tartrate (Rochelle salt), either 1 g. ferrous ammonium sulphate or 1.5 g. ferrous chloride hydrate, either 0.7 g. nickelous sulphate hydrate or 0.2 g. nickelous chloride hydrate, in 20 ml. water and adding sulphuric or hydrochloric acid to bring the pH value to 4, adding 0.5 ml. of a 0.1% PdCl2 solution containing 0.1% HCl, and then adding 3.5 ml. of 29% NH4OH to bring the pH value to 9.2.  A second plating layer is preferably electrolessly deposited over the first from a Ni-Fe hypophosphite plating solution at 75  DEG C. comprising 20-50 g./l. nickelous chloride hydrate, an amount of ferrous chloride e.g. 25 g./l. corresponding to a ratio of Ni to Fe ions 1.48 to 2.73, 50-150 g./l. sodium potassium tartrate, 10-50 g./l. sodium hypophosphite and enough NH4OH to bring the pH value to 8-12.  The second plating layer may be of composition 75-81% Ni, less than 1% P and balance Fe, and made anisotropically ferromagnetic for forming magnetic storage elements (see Division H1) by locating the substrate e.g. one or more glass cylinders 20 (see Fig. 4) in an orientating magnetic field, provided (as shown) by an electric current flowing in a wire 33 threaded through the glass cylinders, or by permanent magnets, during the or each deposition.  Air is preferably excluded during the second plating by covering the second solution 25 with a silicone oil layer 28.

IPC: G07F17/14
Filed: 1967-10-19
Abstract: 1,190,784. Inductive control of apparatus; interference suppression in radio receivers. M. WILCOX. 19 Oct., 1967 [28 Dec., 1966], No. 47734/67. Headings H4L and H4U. In a vehicle detection system a fixed-frequency self-contained transmitter unit mounted on a vehicle induces energy in a tuned horizontal loop disposed at approximately ground level, said energy being amplified and rectified to provide an output signal. A transmitter unit 2, Fig. 3, comprises a transistorized oscillator, operating at a frequency in the range 50-400 kc/s., in which is connected a transmitting coil 20, of about 2¢ inches diameter. The transistor and other components and the coil are potted in epoxy resin and power is supplied continuously by a replaceable battery 24. A threaded stem 39 projects from the top of the unit, and by means of a special nut 43 it may be fixed under the vehicle to either a horizontal or a vertical member, with the coil 20 approximately horizontal. As described for application to a car park in which a ticket is normally automatically issued by a machine (12), Fig. 1 (not shown), as a vehicle enters and depresses a treadle (8) operating a switch (9), but in which it is desired to prevent a ticket being issued to a contract parking vehicle (1), said vehicle is fitted with a transmitter unit (2) and a detector loop (5) is provided adjacent the treadle (8). A signal originated by induction in the loop (5) stops the issue of a ticket and may switch on an indicating lamp (18). A further loop (13), or another treadle-operated switch, is provided for re-setting the machine (12) as the vehicle (1) moves on. The pick-up loop 5, Fig. 5, is tuned by a capacitor 102 and a variable inductor 103, and its output is amplified by a tuned amplifier comprising transistors 99, 113, 121, and having a manual gain control 130. Direct current output in response to a signal is obtained by diodes 134, 141 via a transistor 129, and is applied to the base 148 of a normally non-conductive transistor 149, and to a voltmeter 144. Energization of the coil 5 causes the transistor 149 to conduct, and operate a relay 154 which disconnects the ticket machine and connects the indicating lamp. A squelch circuit comprises a normally conductive transistor 156 in series with the transistor 149. A resistor 162 is connected between the output side of the diode 141 and the base of a normally non-conductive transistor 161. The collector of the transistor 161 is connected through a capacitor 167 to the base of the transistor 156, and said capacitor is connected to the positive supply line by resistors 160, 166 each of much higher value than the resistor 162. The charging time constant of the capacitor 167 is much less than its discharging time constant, and normally slowly rising signals do not cause the transistor 156 to become non-conductive, but only impulsive signals such as static. The relay 154 is self-holding through contacts 172, 173 and is restored when the contacts 176, 177 of a second detector equipment are opened as the vehicle moves on.
