Title: Resonant cavity tuning device
IPC: H01P7/06
Filed: 1945-12-14
Abstract: 617,421. Electric resonators. PHILCO RADIO & TELEVISION CORPORATION. Dec. 14, 1945, No. 33902. Convention date, Feb. 29, 1944. [Class 40 (viii)] [Also in Group XL (a)] A rotatable tuner for an electric resonator is disposed with its axis extending transversely of both the electric and magnetic fields of the oscillations and includes a conducting member spaced laterally from the axis of rotation and movable between two extreme positions, in one of which the member forms a condenser of substantial capacity with one of the walls of the resonator and effects minimum displacement of the magnetic field, whereas in the other position the capacity is negligible while the member acts as a short-circuiting loop substantially affecting the magnetic field. In the construction shown, the tuner includes two members 5a and 5b which in one position form condensers with the top and bottom of a resonator in which they are situated. In an alternative construction, the tuner only bears a single member, in which case it has to be electrically connected to the wall of the container opposite to that with which the member forms a condenser. The element may be mounted on a spindle of dielectric material or a metal spindle if it passes through the wall at a point of zero current flow. The tuner 34 may be used in a reflex velocity modulation tube in which the resonator is formed of two semi-annular members 27 and 28, two semiannular clamping plates 29 and 30, and an annular clamping plate 31 with clamping screws 32.

Abstract: 1,014,199. Dishwashing machines. FRAME S.A. Sept. 5, 1962 [Sept. 8, 1961], No. 34022/62. Heading A4F. A dishwashing machine comprises an auxiliary chamber 13 at the lower end of the washing chamber in which two centrifugal pumps, viz. a pump 15 supplying washing liquid to a sprayer 46, and a drain pump 16, are mounted on a common shaft 17, the drain pump 16, which is of a type which is operative in a single direction of rotation only, being continuously connected to an external drain. During the washing operation the shaft 17 is so rotated by a driving motor (not shown) that the drain pump 16 is inoperative, whilst water issues from the feed pump 15 to be forced past stationary vanes 56 which reduce or eliminate swirling movement therein before it discharges from the sprayer 46. The latter has a spherically curved portion 47 resting on a conical seat in an annular member 50 so that it may be revolved and rotated by the action of the water flow on a member 52 dependent therefrom. For draining the motor is driven in a reverse sense to operate the drain pump 16, during which operation the pump 15 may or may not be operative. The used washing liquid is filtered through a strainer 35 which has apertures 58 through which the liquid returns to the feed pump 15 and two elongated apertures 59, of larger crosssectional area than the apertures 58, through which the water flows only when being discharged by the drain pump 16.

Abstract: 741,789. Switching systems for heating resistors. STENSHOLMS FABRIKS AKTIEBOLAG. Dec. 8, 1953 [Dec. 9, 1952], No. 34139/53. Class 38 (4). An energy regulator for heating resistors 18, 19, or the like, comprises an operating shaft 6 carrying cams 5, 15 which control, respectively, the setting of a thermally-operated cycling switch 2-4 and the opening and closing of a pair of switch contacts 16, the arrangement being such that over an initial angular range of movement of the shaft the setting of the cycling switch, which is heated by the passage therethrough of the current traversing resistor 18, is progressively increased so that the energy input to resistor 18 is progressively increased also. Over this range cam 15 maintains contacts 16 open, so that resistor 19 is not energized. Over a second range of angular movement of the shaft (separated from the first range by a short gap in which the cams cause both contacts 4 and 16 to be open) cam 5 again causes the energization of resistor 18 to increase progressively with increasing rotation of the shaft but cam 15 switches resistor 19 directly across the supply. In a final position of the shaft a further cam 10 closes contacts 11, there. by short-circuiting the cycling switch, so that both resistors are permanently energized. In another arrangement a third resistor is subsequently connected in parallel with the resistor 19. A further arrangement provides for the following connections : (a) two resistors in series controlled by the cycling switch, with or without a permanently energized third resistor, (b) one resistor permanently energized, (e) two, or three, resistors permanently energized in parallel. Specifications 587,947, [Group XXXVII], and 587,953 are referred to.

Filed: 1933-12-07
Abstract: 419,631. Electric incandescent lamps with cut-outs. STRONG, F. G., 12, Hamsell Street, Jewin Street, London. Dec. 7, 1933, No. 34480. [Class 39 (ii).] In an electric incandescent lamp having thermo-sensitive means subjected to the action of heat generated by the lamp and operating periodically to secure and interrupt the emission of light by the lamp, the periodic interruption of the emission of light is effected by the intermittent shunting or byepassing of the current supplied to the lamp. In one form two thermally warp able elements 7, 8 extending upwardly from the tops of conductors 5, 6 have the filament 9 connected across them with its ends secured, for example, by welding. The members 5, 6 are secured within the pinch 4 and connected respectively to the screwthreaded shell 1 and centre contact 7<a> of the lamp bulb. Heat generated by the filament 9 produces warping of the members 7, 8 which bend so that they make contact one with the other and short-circuit the filament. In a modification only one thermally warpable element is employed, this being secured at one end to the upper end of one conducting-rod and extending downwardly at an angle to a position near to the lower end of the other conductor with which it makes contact when the filament becomes heated. When a number of such lamps are connected in series in festoons a protective resistance such as an ordinary incandescent lamp or a baretter or the like is connected in series therewith to prevent the fuses from blowing in the event of all the flashing lamps being short-circuited simultaneously.
