Title: Improvements in or relating to electric torches, spotlights and the like
IPC: F21L4/00
Filed: 1933-03-09
Abstract: 413,805. Electric battery lamps. EVER READY CO. (GREAT BRITAIN), Ltd., Hercules Place, Holloway, and KONINGSVELD, M. VAN, Coombe, Minchenden Crescent, Southgate, both in London. March 9, 1933, No. 7182. [Classes 39 (ii) and 75 (iv).] In an electric torch, spotlight, or the like, of the kind wherein the lamp bulb and its associated socket are adapted to be slidden axially of the reflector for focusing purposes, the socket being in the form of an internally screw-threaded tube passing through a disc or member closing the end of the battery casing, the socket 5 is slidably mounted within a barrel or housing 2 which, internally is of non-circular cross section, a part of the socket contacting therewith being similarly shaped so as to prevent turning movement of the socket within the housing. In the example the housing 2 consists of an octagonal tube, with a neck 3 which is swaged outwardly at one or more parts 4 to maintain the housing within a closure disc 1 of metal or insulating material. The main portion of the socket 5 is cylindrical, with a bottom flange 6 of cross-section corresponding to that of the housing 2 and forming a seating for the lower end of a helical spring 8 which surrounds the cylindrical part of the socket and abuts against the reduced neck of the housing, thereby tending to hold the lamp bulb in a position adjacent to the reflector. An insulating bush 10 screwed into the bottom end of the socket carries an axial rivet 11 providing a current path between the central contact of the bulb and the electrode 13 of battery 15. Focusing is effected by screwing on an end cap 16 provided with a protuberance 17 which presses on the bottom end of the battery and forces the latter inwardly. The switch 18 controls a resilient strip 19 which bears upon the outer surface of the housing 2 to close the circuit.

Title: Improvements in or relating to resonator systems for discharge tubes
IPC: H01J25/32
Filed: 1953-03-17
Abstract: 720,820. Velocity-modulated tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 17, 1953 [March 20, 1952], No. 7334/53. Class 39 (1) [Also in Group XL (b)] In a velocity-modulated brake-field oscillator tube of the type having a resonator system comprising a Lecher line having two conductors each of a length equal to an odd number of times a quarter of the operating wavelength, said conductors being fitted in a conductive box and connected at one end to each other and to the conductive box, an additional Lecher line is provided in the box to ensure that the voltages on the conductors of the first line are in anti-phase with respect to each other. The tube shown has a resonator system comprising a box-shaped conductor 2 and a short-circuited Lecher line 3, 4 whose length is one quarter wavelength of the oscillations to be produced This resonator system is maintained at a high positive voltage relative to the cathode 7 by a source 13, and a brake-field electrode 12 is maintained at a negative voltage relative to the cathode 7 by a source 14. Electrons from the cathode 7 are formed into a beam by known means (not shown) and are velocity-modulated in passing through apertures 8, 9, 10 and 11 in the resonator system. The beam reflected by the electrode 12 is density modulated and the electrons in passing through the apertures 11, 10, 9 and 8 give up energy to the resonator to maintain the oscillations therein, and energy may be withdrawn from the resonator by known output means (not shown). It is a necessary condition for efficient operation that the voltages on the conductors 3 and 4 should be in anti-phase, but the dimensions of the system are such that the conductors 3 and 4 may oscillate in phase with respect to the conductor 2. To prevent this, a further Lecher line 5, 6 is provided at right-angles to the line 3, 4. The conductors 5 and 6 are connected at opposite ends 15 and 16 to the wall of the conductor 2 and are coupled capacitively at their centres 17 and 18 to the free ends of the conductors 3 and 4. The length l of the conductors 5 and 6 is given by l = #/# tan #C/C+2K where # is the wavelength of the oscillation produced, C is the capacity of each conductor per unit length relative to the inner wall of the conductor 2, and K is the mutual capacity per unit length of the conductors 5 and 6. The Lecher line 3, 4 is highly capacitively loaded by the line 5, 6 for in-phase oscillations and the resonance frequency for said oscillations is so far shifted as to avoid interaction with the desired anti-phase oscillations. It is fundamentally possible for the centres of the conductors 5 and 6 to be connected directly to the ends of the conductors 3 and 4, but capacitive coupling is preferable.

Title: Dehydration of acetone
IPC: C07C49/08
Filed: 1943-05-10
Abstract: 571,661. Dehydration of acetone. SHELL DEVELOPMENT CO. May 10, 1943, No. 7401. Convention date, May 26, 1942. Drawings to Specification. [Class 32] Anhydrous acetone containing 0.3 per cent. water or less is obtained by submitting an aqueous mixture of acetone to fractional distillation in a fractionating zone maintained at a subatmospheric pressure. The process is preferably carried out on a mixture containing from about 1 to 50 per cent. by weight of water and the fractionating zone is preferably maintained at an absolute pressure between about 200 and 400 m.m. The mixture distilled may or may not contain other components, e.g., isopropyl alcohol. In the example an aqueous acetone mixture containing acetone and water in the weight ratio of about 2 to 1 was continuously distilled in a fractionating column provided with 49 plates. The absolute pressure in the column was about 300 m.m. When the reflux ratio was 1, the acetone product contained about 0.38 per cent. water. Increasing the reflux ratio to 2 resulted in an acetone containing only about 0.14 per cent. water. A still greater increase of the reflux ratio to 3 gave an acetone containing only about 0.04 per cent of water. The same material was distilled in the same apparatus, the pressure in the column being maintained at about 500 m.m. (absolute). Reflux ratios of 2, 3 and 4 resulted in an acetone distillate containing, respectively, 0.32, 0.18 and 0.09 per cent. of water. In each of the foregoing distillations the aqueous acetone mixture was introduced into the column at the fifteenth plate from the bottom.

Title: Miners' safety lamp
IPC: F21L23/00
Filed: 1929-03-07
Abstract: 318,481. M³ller, G. Sept. 3, 1929. [Convention date.]. Carburetted-air lamps; miners' safety lamps.- In a miners' safety lamp a gaseous mixture is made by passing compressed air over a porous material containing a volatile fuel, and is employed to render a mantle 11 or other body incandescent. The reservoir 1 is filled with a porous medium 3, e.g. felt, cotton wool or pellets of clay, coal &c. saturated with benzine supplied through a feed hole 4. On the reservoir is arranged a closed chamber 6 through which pass one or more tubes 7 each having a wick fed with the fuel and ignited before the upper part 2 of the lamp is screwed on to the reservoir and secured by a magnetic lock. The chamber 6 is secured to the reservoir 1 by a bolt 8 passing through a central tube 20 and engaging a nut 9 carrying an insulating tube 10 which supports a gauze 12 and the incandescent mantle 11 of woven platinum. The. upper part 2 of the lamp comprises concentric cylindrical glasses 13, 14 surmounted by gauzes 15, 16 and the lamp is connected with an air pressure main by a union 18 and flexible tube 17. Some of the compressed air flows through an opening 19 to the reservoir, penetrating the porous mass, the carburetted air passing through the central tube 20 and an opening 21 into the chamber 6 where it mixes with air entering the chamber through an opening 22. The mixture passes through a hole 23 to the mantle and is ignited by the flame f. A further part of the compressed air entering the flame. space through openings 24 serves for cooling, and the annular space between the glasses 13, 14 is in communication with the compressed air space by holes 25. Should the outer glass 14 become broken the resulting fall in pressure stops the supply of air through the opening to the reservoir 19. The flame f serves as an illuminating flame during travel to the working place; this flame may be replaced by an electric lamp and accumulator housed in the reservoir 1, ignition being then effected by a cerium-iron or electric spark or other means. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the formation of the gaseous mixture by forcing the fuel into the compressed air through fine jets, or by forcing the air into the mixing chamber through pornus tubes washed by the fuel. This subject-matter does not appear in the Specification as accepted.

Abstract: 671.752. Filling tanks. KSIESKI. K. March 29, 1950 [April 7, 1949], No. 7880/50. Class 21 In a system for filling two or more fuel tanks in an aircraft the fuel is passed to the tanks through a selector unit carrying valves, one controlling the inflow to each tank. The valves of the tanks not being filled act as safety valves for a tank being filled, permitting byepassing of fuel to their tanks in the event of excess pressure due to over-filling. In the system shown the selector 9 and manifolds 10, 11 to the tanks 12, 13, are contained in the trailing edge of the wing, a normal fuelling connection 17 being available for attachment to the hose of a ground pumping unit 50. The valves 32, 33 are opened singly for fuelling by a handle 25 carrying a cam 27 engaging their stems. Excess pressure in the unit causes the unopened valve to open against its spring to byepass fuel to its tank. Additional safety devices comprise level regulating float operated switches 45, 46 and a pressure operated switch 47 connected in series through earth with the pumping unit 50. The circuit passes through a switch 40, or 39, the respective one of which is closed when a valve is opened by the cam 27, to close the circuit for pumping. A rupture plate may also be fitted in the manifold or in one tank.
