Abstract: 678,037. Leading-in wires for electric incandescent lamps. BRITISH THOMSONHOUSTON CO., Ltd. March 20, 1950 [April 27, 1949; April 27, 1949], No. 6881/50. Class 39(ii) In an electric incandescent lamp arranged to prevent damage to the filament when subjected to jar or shock, the filament is mounted between a pair of leading-in wires each supported at one end from the wall of the bulb and extending inwardly therefrom in the same general direction, each leading- in wire comprising two portions 24, 25 lying in the same common axis, with adjacent ends of the portions spaced apart and interconnected by a coil spring 26 fitting over and gripping them tightly, thereby providing a resilient support for the filament 20 to which additional intermediate support is given by an anchor wire 22 with one end embedded in a glass rod 29 supported transversely between the leading-in wires. As shown, the leading-in wires are supported solely from metal ferrules 10 to which their outer ends are soldered, contact lugs 8 with screw terminals 11 being soldered to the ferrules. In a modification, Fig. 3 (not shown), the portion of the coil spring at the gap between the ends of the parts 24, 25 of the leading-in wires is of greater diameter than the portions gripped upon the wires. In a further modification, Fig. 5, each leading-in wire 58 is bent into three parts consisting of outer and inner end parts 67, 68 extending in the same longitudinal direction, and an integral, intermediate, laterally-extending, circularlycurved portion 66 located approximately in a plane transverse to the inleads and imparting flexibility to the filament-supporting end of the mount.

Abstract: 269,148. Mirlesse, I., and Kousnetzoff, A. I. April 7, 1926, [Convention date]. Recovering waste lubricants.-Used lubricating oils of thermal engines are reconditioned by filtering cold to remove relatively large solid particles, heating by the exhaust gases of the engine to vaporize water and light hydrocarbons, and filtering hot to remove any solids remaining. In the continuously operating device shown, used oil is drawn from the crank case 2 of the engine E by a pump 24, forced through a filter 5, spread as a thin sheet on a curved hollow plate 28 heated by gases from the exhaust pipes 8, 10, and passed through a filter 22 of close wire netting, fabric, or a porous body to a tank 23, a refrigerator 25, a pump 26, and a pipe 27 to the engine. The vapours from the oil on the heated plate 28 pass out of the lagged chamber 7 by a pipe 14 to the liquid fuel tank 21, or to the engine cylinders, the atmosphere, or to a condenser. The refrigerator 25 may be cooled by water from the radiator, a separate fan 29, or by the liquid fuel. The filtration may be effected under reduced or raised pressure. In modifications (1) the heating chamber 7 and tank 23 are placed on the bonnet of the engine or on the radiator so that the purified oil flows by gravity to the engine, the pump 26 being omitted; (2) the oil is heated by passage through a coil contained in a preferably cylindrical chamber through which the exhaust gases are passed, or by passage upwards through staggered plates in a chamber traversed by pipes through which the exhaust gases pass, two external filters in parallel being preferably fitted so that one may be cleaned without the operation being stopped; (3) the tank 23 is separate from the chamber 7; (4) both pumps may be omitted. the oil being treated in batches taken periodically from the crank case and being removed periodically from the tank 23.

The suspension may be applied to the support in any suitable manner, but particulars of several methods of application are given in the Specification. Preferably the glass has a softening point below 500‹ C., and the liquid consists of a mixture of a liquid that boils below 80‹ C., and another that boils between 80‹ C. and 200‹C., such as carbon tetrachloride and amyl or butyl alcohol. Zinc sulphide or zinc-cadmium sulphide may be used as the' luminescent material. A suitable glass is composed of 22.6 per cent. zinc oxide, 11.4 per cent. of sodium oxide, and 66 per cent. of boron trioxide.

Title: Improvements in wireless aerials
IPC: H01Q5/364
Filed: 1956-03-09
Abstract: 806,120. Radio aerials. SYKES, B. June 7, 1957 [March 9, 1956], No. 7466/56. Class 40 (7). A wireless aerial suitable for use at frequencies of the order of 200 Mc/s. comprises a skeleton slot or closed frame section combined with a V-type section which extends in a plane at right angles to the plane of the slot, the lengths of the V-section elements and the slot or frame section elements being resonant at substantially the same frequency. The feeder is connected to the apex of the V-section which has its open ends connected to opposite sides of the slot which, in one embodiment, is square as in Fig. 1. Due to changes of reactance with frequency of the two aerial sections tending to cancel, the feed impedance at the apex of the V-section is substantially constant over a range of frequency. The aerial is directional in a direction from the apex of the V to the slot. For two band operation, say Bands I and III, two Band I dipole sections are mounted at the joins of the V-section and the slot, these sections being preferably colinear. This aerial resonates only at one frequency and is non-directive unless provided with a reflector and/or director whereas the V and slot aerial is directional and resonates satisfactorily over a wide frequency range. The aerial matches to standard lowimpedance coaxial cable.

Title: Method for the arbitrary distortion and correction of wireless or wire transmitted alternating currents, such as speech and signal alternating currents, by means of superimposed disturbance alternating currents

Filed: 1933-03-13
Abstract: 401,564. Secret telephony &c. K€SEMANN, E., 15, Bernhard Beyerstrasse, Steinst³cken, near Berlin. March 13, 1933, No. 7543. Convention date, Jan. 20, 1933. Drawings to Specification. [Class 40 (iv).] A method of secret transmission of telephony, television &c. consists in superposing on the signals, before transmission, distorting signals from a phonograph record, and counterdistorting at the receiving end with signals from a similar record in counterphase with the distorting signals. The received signals may be recorded and counter-distorted during reproduction, and the transmission may include a wireless link. Synchronization may be effected by the transmission of impulses recorded on the said record or on an auxiliary record. The records may be photographic, magnetic or ordinary disc records, an iron disc with an irregular periphery moving between the poles of an electromagnetic pick-up and a glass disc with a photographic recording are particularly described. The distorting currents may be amplified before superposition, and the amplitude of the counter-distorting currents is adjusted to prevent over-correction, line distortion being compensated by equalizers. The distorting currents may be derived from two or more records or by picking up from two or more points of one record and secrecy may be further ensured by changing, continuously if desired, the position of the pick-ups, these changes taking place according to a plan known at the receiving station. Where two records are used, the phase relationship between the correcting currents may be adjusted by temporary variation in speed of one record.

The tube 10 may be clamped on a pipe or materials to be heated are passed through the tube.  The outer surface of the tube 10 is roughened, e.g. by etching or sand-blasting, and the alpha alumina particles are introduced into an oxy-hydrogen or oxy-acetylene flame.
