Title: Improvements in and relating to electrical indicating, measuring or control apparatus
Inventor: OUGHTON HARRY GEORGE
IPC: G01K17/16
Filed: 1964-02-06
Abstract: 1,085,642. Measuring heat flow electrically. FOSTER INSTRUMENT CO. Ltd. Feb. 5, 1965 [Feb. 6, 1964], No. 5067/64. Heading G1N. Apparatus for measuring the quantity of heat contained in a flowing fluid comprises a circuit incorporating a multi-bank, four-position switch 5 (Fig. 1) which is cyclically operated to enable (a) the rate of flow of the fluid to be measured and recorded, when the switch is in position 1, (b) the temperature rise of the fluid to be measured, when the switch is in position 2, (c) the temperature rise to be recorded, when the switch is in position 3, and (d) the heat energy absorbed to be measured and recorded, when the switch is in position 4. The rate of fluid-flow is sensed by a transducer 10, whose output voltage is compared with the unbalance voltage from a D. C. bridge 12. Any difference is amplified at 18 to energize a motor 19 which drives the slider 53 of a potentiometer 13 in the bridge circuit until the voltages are equal. The position of the slider 53 is then indicative of the rate of flow, and is recorded at 56.  The temperature of the fluid at the inflow and outflow is measured by temperature-sensitive resistors 15, 16, connected into a bridge circuit 14. The bridge unbalance voltage is amplified at 18 to energize a motor 20 which adjusts the slider of potentiometer 17 until the bridge is balanced. The motor 20 also drives the slider 52 of a potentiometer 11 across the flowmeter 10, so that the position of both sliders is indicative of the temperature rise of the fluid. Potentiometer 11 is next connected in parallel with  potentiometer 13 to form a bridge circuit which is automatically balanced by motor 19, and recorded at 56. Finally, flowmeter 10 is again connected across potentiometer 11, the voltage at the slider 52 which is now indicative of the product rate of flow x temp. difference, i.e. heat energy absorbed, is automatically balanced against that on slider 53 of bridge 12, and is recorded at 56. Automatic compensation for variations in e.g. density with temperature can be effected by temperature-sensitive resistors in the circuit. In an alternative arrangement Fig. 2 (not shown), a single motor is used, operating through selectively energized clutches.

Filed: 1972-02-07
Abstract: 1400462 Cathode ray display tubes; cathode materials MULLARD Ltd 31 Aug 1972 [7 Feb 1972] 5567/72 Heading H1D A display device suitable for alpha-numeric display comprises an array of secondaryemissive cathodes 10 which are selectively controlled and which are flooded by electrons from a radioactive source 20 (Fig. 3), the emission from the selected cathodes being amplified by a channel multiplier 11 and passing to a luminescent screen 18. In the arrangement illustrated the cathodes form a 7 x 5 rectangular array and each cathode is mounted on a metal substrate provided with an individual connection 2 and disposed in a shallow cavity in an insulating block 6. The source 20 may comprise a copper grid coated on one side with titanium and coated on the other side with copper to absorb emitted electrons and prevent them from passing into the channel multipliers; carbon is a suitable alternative radioactive material. Electrons from the radioactive source induce secondary emission at the cathodes 10 and since such secondary electrons have an energy of less than 10 volts the switching potentials applied to the cathodes may be only a few volts and the cathodes may be switched by means of integrated circuits. A cross-bar addressing system may be used if the channels in plate 11 are connected together in rows whilst the cathodes 10 are connected together in columns; in this case the source 20 is spaced from the input surface of plate 11. A colour display may be provided by using discrete phosphors of different colours for the screen 18.

Press-button switches; bases.-A switch for closing the circuit of an electric horn on a motorvehicle is operated by pressure in any direction upon a dome-shaped cover member 13 which carries an annular contact-plate 15 flared inwardly at 16 and held on the cover by a rivet-like member 18 moulded in the cover 13 and riveted over at its inner end, with an interposed washer 19. The inwardly projecting end of the contact plate, together with the rivet, pass freely through a fixed plate 21 which is held in position by a screw 24 which also secures a contact plate 25 carrying one of the terminal screws. The plate 21 is held also by a screw 23 which electrically connects it, through a plate 29, to the spring 27, which normally holds the cover in the ' floating ' position shown. The contact plate 25 is thus electrically connected with the movable contact plate 15. The fixed contact is constituted by a lipped annulus 2 secured to the base of a depending tongue 5, Fig. 5, hooked into a recess therein, and by a clip 9 hooking over the annulus and bent under a contact-plate 11 which carries the second terminal, and is held by the clip. When pressure is applied at the side, the cover fulcrums about a point on the edge of the washer 19, and the contacts 15 and 2 are brought into engagement. The base 1 may be mounted on a secondary base and held there by a flanged casing 31 secured by the fixing screws. Alternatively, the base 1 may be cylindrical so as to permit of its insertion within the steering pillar of a motor-vehicle. In this case, tile contact plate 11 may be bent up so as to engage the interior of the steering pillar, and a setscrew passing through the pillar may secure the switch and afford an earth connexion through the pillar to the contact 2.
