Title: Improvements in or relating to discharge tubes adapted for generating oscillations
IPC: H01J25/10
Filed: 1946-04-10
Abstract: 619,514. Velocity-modulated tubes. PHILIPS LAMPS, Ltd. April 10, 1946, No. 11008. Convention date, Nov. 27, 1941. [Class 39 (i)] Velocity-modulation apparatus for generating oscillations comprises velocity modulating and energy extracting electrodes 8, 9, 10; 12, 13, 14, Fig. 1, surrounded by drums 19, 20, a drift tube 11, and a feedback line 21, 22, and the oscillatory system so formed is arranged wholly inside the discharge tube envelope, as shown, or forms parts of the tube envelope. The oscillatory system together with mica-discs 24, 25 and discs 26, 27 is located by re-entrant parts 23 of the envelope, the discs 24, 25 being notched, Fig. 2, so that when the unit is inserted into the envelope it is locked in position by a slight rotation. Energy is taken from the electrode 12, which may also serve as an aerial, by a movable conductor 29 capacitatively coupled thereto, which may be arranged in a re-entrant portion of the tube wall or may be arranged inside the tube wall, in which case it is adjusted by magnetic means. Alternatively, energy may be abstracted inductively by a movable or stationary coupling loop, or from a separate electrode assembly which may be constructed similarly to the electrode system 12, 13, 14 between the oscillatory system and the electrodes 6, 7. The separate output electrode assembly may be used in conjunction with an output coupling device in the oscillatory system so that the amplitude and frequency of the output from the separate output electrode assembly can be controlled. The envelope 1 is of glass or quartz and an axial magnetic field focuses the electron beam. In a modification, Fig. 4, the walls of the drums and of the feedback line form parts of the discharge tube wall. The output resonator 32 is also drum-shaped and is tuned by displacing screws 38 which causes movement of the rigid wall 39 and collector 6, such movement being permitted by the flexible wall 34. The collector electrode 6 is water cooled, a cooling jacket 37 being provided. The energy abstracting conductor 40 may serve in addition as an aerial. The outer conductor of the feedback line 21, 22 is formed by a cylindrical bore in a solid cylindrical block 31. In a somewhat similar arrangement, Fig. 3 (not shown), the output resonator is timed by a screw and may be air-cooled. In a further modification, Fig. 5 (not shown), the outer conductor of the feedback line is formed by the cylindrical surface of a bore in a wall common to the drums of the oscillatory system and by the cylindrical drum walls and drift tube wall. The oscillation frequency may be equal to the fundamental frequency of the oscillatory system or to a harmonic thereof, and the output resonator such as 32, Fig..4, may be excited at a frequency equal to or a harmonic of the frequency of the oscillations generated by the oscillatory system.

Abstract: 1,152,793. Protective arrangements. FUCHS ELECTRICAL INDUSTRIES (PTY.) Ltd. 10 March, 1967 [11 March, 1966], No. 11436/67. Heading H2K. In an earth leakage protective arrangement in which the signal from a core balance transformer 2 effects the operation of a relay 25, 26 through an amplifier and a trigger device, the " power " supply for the amplifier and device is derived from the main protected A.C. circuit through a capacitor 16 which functions as a voltage dropper. As shown, unbalance between the currents in the single turn primary windings 6, 7 of the transformer induces current in the secondary winding 4 which with a capacitor 9 forms a tuned circuit. The resulting signal is applied to the base of a transistor 10 to render it conductive and the output of the transistor acting through a current limiting resistor 19 triggers a silicon controlled rectifier 20 which conducts to energize the relay coil 25. The " power " supply for this circuit is obtained from the main supply conductors through conductors 14, 15. A shunt trip coil of a main circuit-breaker is connected in series with the line 15 so that when the relay closes its contacts 26 the shunt trip coil is fully energized and trips the circuit-breaker. A test winding 5 on the core-balance transformer is controlled by a switch 41.

Title: Improvements relating to quick-cooking cereal or farinaceous food products
Inventor: WATSON ROBERT DOUGLAS
IPC: A23L7/196
Filed: 1962-03-26
Abstract: In producing a dried, quick-cooking starch-containing cereal food, such as cleaned, husked, puffed rice grains which can be re-hydrated quickly in hot or boiling water, the cereal is soaked in water, e.g. at 170 to 200 DEG  F., or dried, e.g. in a stream of air at 150 to 280 DEG  F., or by infra-red rays, to bring its moisture content to a desired value between 25 and 30% by weight, when soaked, or between 2 and 6% when dried.  The resulting product is soaked in water at a temperature above the gelatinization temperature of the starch but below that at which the starch granules would burst, e.g. 170 to 200 DEG  F., until the products has absorbed more water, e.g. between 3 and 4 times its weight thereof, and gelatinization of the starch is initiated, any excess water is removed and gelatinization is substantially completed, without further addition of moisture, by maintaining the product substantially at the latter temperature and at atmospheric pressure.  The gelatinized product is then dried in a stream of air at 250 to 280 DEG  F., or by infra-red rays or under vacuum.

Title: Improvements in or relating to regulating apparatus for alternating current voltagesin connection with the charging of batteries
IPC: H02J7/02
Filed: 1941-09-09
Abstract: 562,673. Charging batteries. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Sept. 9, 1941, No. 11554. [Class 38 (iv)] A saturated transformer 2, with its primary winding in series with a suitable condenser 3, and an unsaturated transformer 6, with a suitable secondary voltage small in comparison to that of the other transformer, have their secondaries in series and supply a load comprising a buffer battery 11 through a rectifier 9. The arrangement is such that the currentvoltage characteristic, Fig. 7, applied to the load circuit has a portion 13 with slight change in voltage, a portion 14 having a pronounced current limiting character and between the two a " maximum voltage " or hump due mainly to suitable choice of the voltage of the unsaturated transformer. This results in a rapid charge of the battery after discharge and a subsequent trickle charge if load remains light. To prevent too high a voltage on no load, a relay may be arranged to maintain a ballast load in circuit under no load conditions.

Abstract: 256,185. Mannesmannr÷hren-Werke. July 30, 1925, [Convention date]. Radiators.-In a radiator wherein the tubes b, which are pressed out of sheet iron and welded at the seams or else are made out of thinwall e d seamless tubes, are inserted in slots c in connecting hubs a and welded thereto, the . hubs have internal cavities of the external breadth of the tubes so that the lateral sides thereof will support and guide said tubes over a wide surface and so relieve stresses at the welded joints. The edges of the hubs are shaped or recessed as at f, Fig. 5. so as to reduce the thickness of the metal at the weld to equal the thickness of the wall of the tube to be welded and thereby obviate subsequent stresses at the joints due to non-uniform heating. The welded seams l at the bottom of the radiator tubes are inclined as shown in Fig. 1 in order that condensed water may run away freely. The hubs are thickened and screw-threaded at d for connection to similar units.

Abstract: 270,488. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). May 6, 1926. Thermionic generators. -In a valve oscillator, the creation of excessive voltages across the electrodes is avoided by the insertion of a two-electrode discharge tube in the circuit to be controlled. As shown in Fig. 1, a current-limiting diode 13 sets a maximum value to the current flowing in the space-charge grid circuit. In Fig. 3, a diode valve 13 is connected in the grid-filament circuit in such a way as to prevent any reversal of grid current in the event of excessive secondary emission from the grid 2. Alternatively, the diode may be shunted across either the grid or plate inductances of a back-coupled generator so as to prevent excessive grid or plate tensions relatively to the filament. As shown in Fig. 6, the diode permits current to pass directly from the plate to the grid if the tension exceeds a safe value.
