Title: Control device for electric heating appliances
IPC: H05B1/02
Filed: 1964-04-06
Abstract: 1,026,315. Thermal switches. W. BRANDL. April 6, 1964 [April 5, 1963], No. 14185/64. Heading H2B. A thermal control switch includes a controlled heating coil 4 in liquid 3 in a body 1, used to heat a container 2 for example, and the body 1 is in communication with a resilient member deformable by vapour pressure to operate a switch 7 controlling the heating coil, means being provided to adapt the spring characteristic of the resilient member to the vapour pressuretemperature curve such that with increased pressure the resilient member is more difficult to deform. Body 1 communicates with a bellows 9 having a stem 13 acting on switch 7, and a leaf spring 10 bearing on the bellows 9 engages curved stops 22a which displace the support points of spring 10 after a certain movement and thus stiffen the spring 10 with increasing pressure. A knob 18 is used to adjust pressure on a leaf spring 16, carrying a movable slider 20 acting on a tongue 15a bearing on the plunger 7a of pivotally mounted switch 7, thereby setting the operating temperature.

IPC: F04D29/22
Filed: 1967-03-29
Abstract: 1,148,848. Centrifugal pumps. HOTPOINT Ltd. April 17, 1968 [March 29, 1967], No. 14230/67. Heading F1C. A centrifugal pump comprises a one-piece casing 1 in which is rotatably mounted an impeller 6 of flexible form, the casing having an opening (conveniently the pump inlet port 2) through which the impeller, which by reason of its flexibility can be reduced in effective size, can be passed on assembly. The impeller is of rubber, mouled on to the pump shaft 5. On assembly, the shaft 5, with the bearing and sealing unit 4 on it, is passed through the inlet port 2 into the casing 1 until the four paddle blades of the impeller 6 contact the inlet port. Each blade is then folded over on to the next blade to reduce the overall diameter of the impeller to allow it to be passed through the inlet port. The bearing and sealing unit 4 is then secured by nuts 7 and spacer 11 against a mounting bracket 8. The impeller returns to its original shape when it has passed beyond the inlet port. The casing may be a polypropylene moulding.

Title: Improvements relating to prepayment electricity meters
IPC: G07F15/06
Filed: 1928-05-15
Abstract: 309,330. Soc. Genevoise d'Instruments de Physique. April 28, 1928, [Convention date]. Electricity, supplying by meter; price-changing mechanism; mechanism for prepaying rent of meter.-In a prepayment electricity meter, the coin insertion mechanism is connected to the differential quantity mechanism by two transmission gears of different ratios, the gears being automatically changed over from the lower to the higher ratio after the insertion of a predetermined number of coins so that, when the lower gear is in operation, the consumer pays meter rental or basic charges while consuming energy. A shaft 3 of the coin mechanism drives one sunwheel 1 of the usual epicyclic quantity mechanism through gears 7, 8 which engage alternately gears 9, 10 slidable as a unit on a shaft 11 geared to the wheel 1. The unit 9, 10 is guided on rods 12 and is subjected to the action of a spring 13 which presses it downwards so that a cam 14 on the underside of the gear 9 engages the periphery 15 of a rotary numeral wheel 16. The wheel 16 is mounted on a shaft 17 having at its lower end a portion 18 of square section which enters the cash box 19. A collar 24 on the shaft 17 rests on a lever 25 pivoted at 26, this lever having a head 28 which rests on a bracket 29 in the cash box and being pressed up by a spring 27. A wheel 20 slidable on but rotatable with the shaft 17 is normally pressed by a spring 22 into :mesh with the gear 10, the numeral wheel 16 having been rotated from zero a distance equivalent to the basic charge to be paid and shown by the numerals. The coin shaft 3, through the gears 8, 10, rotates the quantity gearing and through the wheel 20 rotates the shaft 17 until the wheel 16 returns to zero, when the cam 14 enters a notch 30 in the periphery 15. The ensuing downward movement of the unit 9, 10 causes the gears 7, 9 to mesh and drive the quantity mechanism at a higher ratio, while the gears 10, 20 are disengaged. The numeral wheel 16 is reset by an inspector, after the cash box 19 is withdrawn. The withdrawal of the cash box allows the lever 25 to raise the wheel 20 out of engagement with the gear 10 while the numeral wheel 16 is being reset. A ratchet wheel 31 on the wheel 16 co-operates with a pawl and holds the wheel 16 in a position corresponding exactly with a coin or traction of a coin inserted.

Title: Improvements in or relating to reflex klystron devices and hollow electrical resonators therefor
Inventor: PEARCE ALBERT FREDERICK
IPC: H01J25/24
Filed: 1954-05-19
Abstract: 807,542. Velocity modulated tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 9, 1955 [May 19, 1954], No. 14634/54. Class 39(1). In a reflex klystron having a cavity resonator arranged to be excited in a harmonic mode by the electron beam passing through a capacity gap therein, a conductive member 14, Fig. 3, is arranged within the resonator in such a position between the inner voltage nodal surface encircling the capacity gap. and outer resonator wall as to provide capacitive loading and so as to decrease the effective capacity of the beam passage gap whereby the electronic tuning range obtainable is increased (for example by variation of the reflector voltage). The capacitive loading member may be a simple cylinder 14 as shown, or a stepped cylinder, Fig. 4 (not shown) assembled in sections or having a longitudinal cut to facilitate assembly and having a conical lower end to mate with flared portion 8 of disc 6, to which it may be welded. Alternatively part at least of the conductive member 14 can be a metallised coating on the glass tube wall portion 2 if the part 2 is outside a voltage nodal surface. This may be achieved by evaporating a silver coating on the tube wall 2 in vacuo, the thickness of the coating being subsequently increased by electroplating. A mask prevents silver depositing over the desired capacity gap. The capacity gap can be a series of apertures or arcuate slots instead of an annular gap. The resonator need not be circular. In Fig. 3 the reflex klystron is of the disc seal type, disc electrodes 6, 7 having honeycomb grids to minimise beam interception. Resonator 12 may have a dielectric plunger for mechanical tuning. If member 14 is less than <SP>#</SP>/ 8  from the outer voltage antinode at the outer wall of the resonator the efficiency decreases. The voltage nodal surface is <SP>#</SP>/ 2  distant from the outer resonator walls and is a cylinder or if the resonator is not symmetrical about the interaction gap the nodal surface is said to be frustoconical. The glass tube envelope usually coincides with the voltage nodal surface to minimise dielectric losses.
