Title: Improvements in electric projection lamps
IPC: H01K1/28
Filed: 1966-02-04
Abstract: 1,113,407. Electric incandescent lamps. GENERAL ELECTRIC CO. 4 Feb., 1966 [26 Feb., 1965], No. 4926/66. Heading H1F. A projector lamp comprises a glass bulb 1b of tubular form having a flattened front face fb and containing a separate concave reflector 8b with its mouth adjacent the face, a filament 9b being mounted between the reflector and the face. With this arrangement, a larger reflector can be employed than in a conventional projector lamp of circular cross-section having the same front-to-back dimension. The reflector is supported by the lead-in wires of the lamp, and may have a glass base with a reflecting coating of vapour-deposited aluminium or silver or a multiple layer interference film or dichroic coating which reflects light and transmits heat. Alternatively the reflector may have a copper base plated with nickel and then coated with vapour-deposited silver. A ballast filament 29 connected in series with the lighting filament 9b is located behind the reflector, and a fuse wire 30 which may be enclosed by a glass insulating tube 31 is connected in series with the ballast. The lamp is made by mounting the reflector, filament and lead-in wires on a flat, preferably circular, glass stem 3b, inserting this assembly into the tubular glass bulb 1b, and heating the neck of the bulb so that it collapses on to the stem to effect a seal. If the neck of the bulb and the stem are of dissimilar shape the wall thickness of the bulb at any point is made inversely proportional to the distance of the point from the centre line of the lamp. This ensures that the thickness of the glass in the seal is substantially uniform. A bulb having such a wall thickness, and with a cross-section in the form of a partial ellipse closed by the flattened front face, may be blown from an initially uniform cylindrical tube.

Abstract: 214,036. Ruben, S. Feb. 20, 1923. Thermal switches; hot-wire relays. - A thermionic tube contains a switch actuated by electron discharge between the cathode and anode; preferably expansion of the anode produced by the discharge operates the switch. The device may be used as a relay, or as a calling, receiving, recording or controlling device for wireless systems. As shown in Fig. 1 the anode 10 consists of a blackened nickel wire or strip, secured at one end to a hollow glass stem 3, and connected to the other end with one arm of a lever 6, the other arm of which maintains the anode in tension and has a tungsten contact 8 engaging with a fixed contact. The fulcrum of the lever is mounted on a nickel-manganese clamp 4 on the stem 3. The discharge from the cathode 13 may be controlled magnetically or by means of a grid 12. In the wireless calling and receiving system shown in Fig. 2 the anode is heated by current in a local circuit comprising a battery 21, a variable resistance 22, and a ballast resistance 24, so as to increase the sensitiveness and to vary the gap between the contacts. The cathode is heated by a battery 18 in circuit with a ballast resistance 19, and the grid is connected through a battery 17 with the input circuit 16. A bell 27 or other signalling device is connected in the relay circuit, and a telephone 23 in the anodecathode circuit. The temperature of the anode may be adjusted so that the relay is unresponsive to signals of the same wavelength but of shorter duration than the calling signal. The contacts may be closed normally and opened by the controlling potentials on the grid. A critical controlling current may be superposed on the circuit of the anode.

Title: Leader gear equipment, particularly for the blind landing of aircraft
IPC: G01S19/15
Filed: 1939-02-16
Abstract: 522345 Leader gear for assisting navigation EN DINGLEY 16 Feb 1939 5156 and 5157 Convention dates 21 Feb 1938 and 21 March 1938 Headings G3R R4 and R32BX A guide-line to enable a pilot to make a "blind" landing is produced by the intersection of the magnetic fields from two leadergear cables 1, 2, Fig. 1, which are fed from a local source 3 of alternating current and create fluctuating fields which gradually diminish in strength towards the landing-point. As shown in plan, the cables converge towards the point 10 where the plane should come to ground, the shunt conductors 6 ensuring that the locus of equal magnetic field-strength in the vertical plane 24 falls off in accordance with the gliding angle. In Fig. 16, the conductors 1<SP>1</SP>, 2<SP>1</SP> are formed as consecutive loops which are coupled through transformers 49, 50 to produce the same effect. Fig. 17 shows another arrangement in which the different conductors of the two branches 63, 64 are coupled to the A.C. source 3 through a common transformer 65, 66, and are grounded at different points to produce a diminishing field towards the landing point, which is near the source 3. Impedances 67 are inserted in each line, the current strength being measured by ammeters 68.  The spreading magnetic field is picked up on two frame aerials 41, 42 and 43, 44, Fig. 14, which are set at an angle to each other along the fuselage of the aeroplane, as shown. The course of the craft is indicated by the point of intersection of the needles of two separate ammeters, each coupled to one of the frames; or it may be shown by a dynamometer or cathode ray tube. The frame aerials may be set at different angles, or may be replaced by a single frame 6 switched in synchronism with the source 3. The two conductors 1, 2, Fig. 1, may be replaced by a single line with graduated shunt-connections to earth. The invention may also be used to guide a ship through a narrow fair-way.

Title: Process for curing semi-fluid polychloroprene with polyamines
IPC: C08K5/17
Filed: 1957-02-18
Abstract: Polychloroprene, which has been prepared by polymerizing chloroprene in the presence of 1.7 to 3.0 per cent elemental sulphur and has a viscosity of one to two million centipoises as measured at 50 DEG  C. with a Brookfield viscometer, is cured at 20-200 DEG  C. by compounding with a polyamine of the general formula H2N(RNH)nH where R is a divalent hydrocarbon radical which may be different in the same molecule but contains no more than 8 carbon atoms and n is an integer less than 5.  Emulsion polymerization using a persulphate catalyst is used and a polymerization modifier particularly iodoform or a mercapto compound is preferably added in the polymerization of the chloroprene and a tetraalkyl thiuram disulphide is added as a short stop and plasticiser.  Suitable polyamine curing agents are the phenylene and toluylene diamines, the diamino diphenylamines, and the bis-(amino-phenyl) phenylene diamines, ethylene diamine, hexamethylene diamine, octamethylene diamine, aminoethyl hexamethylene diamine, triethylene tetramine, tetraethylene pentamine, aminophenyl ethylene diamine and bis-(aminophenyl) ethylene diamine.  A divalent metal oxide such as the oxide of magnesium, lead or zinc or mixtures thereof are preferably also added.  A vegetable or mineral oil may also be added and the usual antioxidants reinforcing agents, pigments, fillers, extenders, odorants and blowing agents.  The ingredients may be incorporated by mixing which may introduce air bubbles which when the mixture is heated above 100 DEG  C. to vulcanize expand and yield a sponge; alternatively, such bubbles may be removed by application of a vacuum.  The compositions may be heated in moulds to prepare for example printing rolls.

Title: An improved method of and apparatus for the separation of solids from liquids by settling
IPC: B01D21/00
Filed: 1930-02-21
Abstract: 356,098. Gravity separation apparatus. ASH CO. (LONDON), Ltd., 63, Lincoln's Inn Fields, and SILK, P. B., 7, Sussex Mansions, Maiden Lane, both in London. Feb. 21, 1930, Nos. 5463 and 34686. [Class 46.] A method of separating solid matter for liquid, for example ash from water which has been used to carry it away from furnaces, consists in admitting the mixture to a tank, allowing liquid to overflow therefrom, periodically interrupting the supply and during such interruption allowing liquid to drain from the tank at a controlled rate, then discharging the solid through gate openings below and finally flushing the tank and gates with fluid jets. The mixture is supplied to the tank 1 through a pipe 8 and a distributing receptacle 32 having a serrated rim. Liquid passes round a baffle 10, overflows into a trough 9 and is discharged through pipes 11, 13. The supply is stopped when sufficient solid has collected, and liquid is then drained off through perforated pipes 14, 15 having depending branches 17, 18 and connected through valves 23, 24 and by pipes 11, 16 with the pipe 13. The solid is then discharged through gates 5, 6, operated by a fluid-pressure device 31 or other manual or powerdriven means. The tank may be supported by a suitable structure 2 so that a truck or the like may be brought into position to receive the solid. Liquid leaking around the gates is collected in channels 19, 20, and discharged through pipes 21, 22 to the pipe 13. Water, steam or gas for flushing purposes is supplied to the tank through nozzles 33. The liquid outlet pipes also have connections 35, 36 for the supply of flushing water. Fig. 2 shows apparatus in which the water passing from the tank 1 through the pipe 13 is delivered to a reservoir 37, from which it overflows through a pipe 41 into a sump 38 to which ash is supplied through sluiceways 39 and from which it is delivered through the pipe 8 by pumps 40. Pumps 44 are provided to draw water from the reservoir 37 for flushing out the pipe connections. The pipe 41 supplies liquid to the sump 38 to compensate for liquid drop during the commencement of pumping operations, the flow through this pipe being controlled manually by a cock 42 or by a float-valve 43. A modification is described in which the reservoir 37 and the ash sump 38 are combined in a single structure which also houses the pumps.
