Title: Improvements in and relating to washing machines
IPC: A47L15/06
Filed: 1933-01-16
Abstract: 403,234. Valves. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Snyder, C. M.; 8, Ellyn Court, Glen Ellyn, and Clark, J. H. ; 1838, South 51st Court, Cicero, both in Illinois, U.S.A.) Jan. 16, 1933, No. 1454. Convention date, Jan. 16, 1932. [Class 135.] A metering valve for supplying a predetermined quantity of liquid to a dishwashing machine, comprises a chamber 113 communicating with an annular passageway 115 which in turn communicates with an inlet 93. The passageway -115 is formed by means of a depending cylindrical member 116, the lower edge of which co-operates with a valve 118 carried by a diaphragm 117. Above the diaphragm is a ring-shaped member 120 provided with a circular tongue 121 co-operating with the cylinder 116 to define a restricted annular orifice at the mouth of the chamber 115 where it communicates with the chamber 113. The passageway 114 communicates with a chamber 122 by way of passageway 125 provided with a valve 124. The valve which is normally closed by a spring is provided with a through passage. Liquid supplied to the metering valve flows through passageway 114 and annular chamber 115 to the chamber 113 from whence it flows through pipe 94 to the dish-washing machine. Liquid also flows through an interchangeable throttle member 124 and increases the pressure in the chamber below the diaphragm until it is sufficient to raise the valve 118 into engagement with the cylinder 116 whereby the flow of liquid to the machine is cut off. The valve remains closed until the pressure under the diaphragm is relieved. This is effected by the liquid in the pipe 93 being byepassed to the pipe 94. The return of the diaphragm 117 to normal position causes a pressure which overcomes the force of the spring 125, thereby lifting the throttle member 124 which opens as a valve. This opens communication between the chamber 122 and a conduit 128 communicating with a drain conduit and releases rapidly the pressure on the chamber 122 so that the member 124 again closes. The metering valve is then in position to measure another quantity of water for supply to the dish-washing machine.

Title: Apparatus for generating or amplifying ultra-high frequency electrical energy
IPC: H01P7/06
Filed: 1943-02-03
Abstract: 592,972. High - freqnency discharge apparatus. WESTERN ELECTRIC CO., Inc. Feb.- 3, 1943, No. 1838. Convention date, Nov. 12, 1941. [Class 39 (i)] An electron beam 25, Fig. 1, is passed through a resonator 20 at a point where the electric field 21 parallel to the beam is of different intensity on opposite sides thereof. In addition, the beam is subjected to a further alternating electromagnetic field which exerts a transverse alternating force on the electrons, causing them to describe the undulating path shown. It is shown that if the transverse field is phased so that the electrons are in the strong part of the field 21 when they are moving against it, and in the weak part when they are moving with it, a net flow of energy occurs from the beam to the field and oscillations are sustained. As shown, the transverse field is produced by plate antenna 60 excited by source 61. The parallel field 21 is produced by similar antenna 67 and a positive feedback path 68 gives the initial excitation of this field, which receives energy from the beam and delivers it to load 64. In an amplifier negative feedback can also be used. In an oscillator, the coupling may be increased until the fields are self-sustaining, the source 61 being then dispensed with; any slight lack of symmetry will initiate the crossed fields, if separate exciting aerials' are not used. Alternatively, two crossed beams 31, 34, Fig. 4, may be used, each beam sustaining the transverse field for the other. It is stated that the action is unaffected by the presence of gas or mercury vapour in quantities sufficient to enable bent tubes to be used. The two tubes in Fig. 4 can then be replaced by a single tube with two arms at right angles ; or short U- shaped tubes may be inserted at the points where the fields are strongest. Gas-filled tubes may be used to excite cylindrical resonators. Tube 54, Fig. 11. may excite spherical resonator 53. Other shapes of resonator are shown. A number of grids spaced along the tubes may be kept at progressively increasing potentials to reduce space charge effects.

Abstract: 1,084,534. Thermal switches; cam-operated switches. RANCO Inc. Jan. 18, 1965 [Jan. 20, 1964], No. 2213/65. Heading H2B. A switch includes a toggle lever 30 pivoted at 31 and movable with a snap-action produced by a toggle spring 36 to actuate contacts 25, 26, a second or operating lever 45 being pivoted to engage lever 30 at 45a and being movable by the thermally expansible bellows 65 against a biasing spring 50. The bellows post 68 extends through an opening 69 in lever 30 to engage a ridge 70 on lever 45, the bellows containing a thermally expansible fluid, and lever 30 has an extension 34 actuating the contacts 25, 26, which are mounted in an insulating member 15. A screw 40 adjusts the position of a bearing member 38 for spring 36 and hence the temperature differential. A further screw 52 adjusts the force of spring 50 to select a range of temperatures within which the switch may operate. Manual rotation of a shaft 60 causes a cam 59 to position a cam follower lever 51 to select the force with which the spring 50 acts and hence the temperatures to which the switch responds within the range selected by screw 52. A projection 75 from cam 59 is engageable with a portion 76a of an arm 76 having a second portion 76b overlying a member 78 of lever 30 so that the contacts 25, 26 may be actuated manually. A third lever (80), (Figs. 9-11, not shown), pivoted to the switch frame and spring-loaded by a second spring (82) adjustable by the manuallyrotatable cam (59<SP>1</SP>) has an extension (80a) engaging the toggle lever (30<SP>1</SP>) only when opening the contacts (25<SP>1</SP>), (26<SP>1</SP>), the lever (80) engaging on abutment (86) of the insulating member (151) when the contacts (25<SP>1</SP>), (26<SP>1</SP>) have opened to allow lever (30<SP>1</SP>) to separate from lever (80). Thus bellows (65<SP>1</SP>) closes the contacts against spring (50<SP>1</SP>) only, but is acted on by both springs (50<SP>1</SP>), (82), when the contacts open again. Manual actuation via spring arm (76<SP>1</SP>) is still possible, as are the adjustments of screws (52<SP>1</SP>) and (40<SP>1</SP>).

Filed: 1955-01-25
Abstract: 779,416. Synchronizing. STONE-CHANCE, Ltd. Dec. 12, 1955 [Jan.. 25, 1955]. No. 2223/55. Class 38 (4). A relay, or contactor, 23 for paralleling two alternating current sources is operated by conduction of a thyratron 12 when the frequency and phase differences are suitably low, the thyratron, under other conditions, being held non-conducting by negative bias obtained from a resistance-capacity circuit 8-10 of long time constant fed over a rectifier 7 with the voltage difference of windings 5, 6 of transformers 3, 4 which are energized, respectively, by the two sources. This bias is high and relatively uniform for large differences of frequency but, as frequency correspondence is approached, falls to a low value over part of each beat cycle and allows the thyratron to conduct. In order that conduction may be initiated early in the cycle of anode voltage of the thyratron, a 90 degree phase-shifted A.C. voltage and, preferably, a small steady negative D.C. voltage are also injected into the grid circuit of the thyratron, the phase-shifted voltage being obtained from transformer winding 14, over the components 18, 19, and the steady D.C. voltage being obtained from a potentiometer 15 energized over rectifier 17 from transformer winding 13 and shunted by a smoothing condensor 16.

Abstract: 878,433. Mechanical switches, without quick action. DON-LAN ELECTRONICS Inc. Jan. 22, 1960 [Feb. 2, 1959], No. 2519/60. Class 38 (5). A switch, particularly for switching H.F. currents, comprises a ring-shaped movable contact supported within a passage by an operating bar moving in the passage, the ring having its axis perpendicular to the axis of the passage, and movement of the bar to one end position causing the ring contact to bridge the end portions of diametrically, opposite fixed contacts. In one embodiment (Fig. 2) the switch is adapted for insertion in a coaxial cable, having threaded connectors 12, 14 for the outer conductor and terminals 11, 13 for connection to the central conductor. The movable ring contact 31 is a loose fit within a longitudinal slot in the operating bar 15, which slides in a transverse passage 16. In each end position, the bar 15 rests on shoulders 20 and is located by spring-loaded balls engaging a groove in the bar 15. In the " on " position the terminals 11, 13 are bridged by the ring contact 31 which has a diameter slightly larger than the spacing of the terminals. The ring is thus distorted a little, ensuring good contact pressure, no contact bounce, and resistance to vibrations, and as the ring is urged between the terminals slight rolling occurs, the contacts thus being self-cleaning. In a second embodiment (Fig. 7) a double-pole change-over switch has rings 59, 60 connecting respective input contacts 47, 48 to one or other of a respective pair of output terminals 40, 41 or 42, 43.
