Title: Improvements in or relating to container filling apparatus
Inventor: THOMPSON JOHN ANTHONY
IPC: B67D7/36
Filed: 1968-12-30
Abstract: 1,249,640. Filling tanks. BURMAH OIL TRADING Ltd. 29 Dec., 1969 [30 Dec., 1968], No. 61676/68. Heading B8T. [Also in Division G1] Container filling apparatus, particularly suitable for filling the tanks of a liquid transporting vehicle with hydrocarbon fuel, comprises a nozzle for insertion into the tank and a level sensing device for preventing over filling. Several of such devices may be used to fill the separate compartments of a vehicle simultaneously, the flow to each compartment being controlled independently. The liquid flow through the nozzle is controlled by a solenoid valve operated through an electrical circuit by a normally open switch 23 closed when the nozzle is at the correct inclination for filling. The switch 23 is in series with a normally open switch 24 closed when the nozzle is in position in the container and in series with a normally closed switch 25 which is opened when the maximum level in the tank is reached. Switch 24 is switched on by the action of spigot 38 in a socket 36 of switch housing 28. The level indicating means comprises a tube 29 closed by a diaphragm 34 (at its upper end). When the end 30 of the tube 29 is submerged by the rising liquid, the pressure increases in the tube and causes diaphragm 34 to move upward, thereby opening switch 25 to stop the liquid flow. When the apparatus functions normally,i.e. without over filling, the liquid is shut off on removing unit 27 from spigot 38. The unit. 27 is attached to a nozzle by a flexible connector 31. Alternatively, the liquid control valve may be actuated by a pneumatic or fluidic circuit energized by means of switches 24, 25.  In a second embodiment (Fig. 4), switch 24 is actuated by a (hinged) member 41, hinged at 43, which actuates the switch when it contacts the rim of a dipstick hole. An extension bar may be provided for member 41 when it is smaller than the hole into which it is to be placed.

Patent GB-2032109-A (GB)
Title: Measuring temperature and thermal flux
IPC: G01K7/01
Filed: 1978-10-17
Abstract: For measuring temperatures and temperature differences (and thus thermal fluxes) the temperature- sensitive devices employed are suitable diodes e.g. highly-doped silicon diodes 11, 12 operated at constant current. At constant current, the voltage drop across such a diode varies linearly with temperature, but the rate is strongly current-dependent; thus adjustment of the respective constant current source 15, 16 enables the temperature sensitivity (mV/ DEG C) of the diode to be adjusted to a standard rate. The voltage drop across the diode and part of a potentiometer 13, 14 in series therewith can be standardised at some reference temperature by adjusting the potentiometer tapping. The differential voltage 17 from two diodes, both standardised, indicates their temperature difference, and the thermal flux between them if the conductivity of the material in which they are mounted (e.g. a metal plug filling an aperture in a vessel wall) is known. <IMAGE>

Title: Frequency Synthesisers
IPC: H03L7/183
Filed: 1979-05-01
Abstract: A frequency synthesiser adjustable in fine frequency steps includes a series connection of an adjustable divider 11 and a multiplier e.g. a phase lock loop 12, wherein the division and multiplication factors differ by an offset integer b. The phase locked loop multiplier may include an adjustable divider 14 or in an alternative arrangement the input frequency F is heterodyned with the controlled oscillator VCO 13 frequency and the difference divided by the offset integer b before application to the loop phase detector 15. Any frequency or phase difference at the detector 15 is eliminated by the control signal from the detector which adjusts the VCO frequency. By making b very much smaller than N, the minimum step change in output frequency is approximately F . b/N<2>. The offset integer b may be fixed or adjustable. By a proper selection of the values of b, N, e.g. using a microprocessor or a look-up table stored in a memory, an output frequency approximating any desired value can be obtained. Further fine step adjustment is obtainable by cascading circuits 11, 12 with a similar arrangement. <IMAGE>
