Title: Improvements in and relating to pinch-base electric incandescent filament lamps
Inventor: WORSDELL WILLIAM JOHN
IPC: H01K1/44
Filed: 1965-06-22
Abstract: 1,100,637. Incandescent electric lamps. GENERAL ELECTRIC CO. Ltd. 9 June, 1966 [22 June, 1965], No. 26352/65. Heading HIF. In an electric incandescent lamp, each lead-in wire 11 is embedded at one end in the pinch 21, is attached to the filament 14 at the other end and is supported at an intermediate point by being sealed through the outwardly turned end 13 of a tube, sealed into or through the pinch, the outer end of the tube being closed. In making the mount assembly, the tube 1 is held in a movable support above a die member having holes through which the lead-in wires pass and is heated and moved downwards into the die member, a mandrel on which engages the interior of the tube to keep this open. The softened glass is pressed outwardly to form the seal for the leading-in wires. The tube may be withdrawn from the mandrel, the part around the outwardly turned end being reheated and the tube again pressed into the mandrel to reinforce the end. A filament 14 is attached to the wires 11 and the assembly pinch sealed into the heated neck of an envelope for the lamp, nitrogen being passed through the tube 1, to keep this open. The outer end of the tube is then tipped off after evacuating and gas filling the lamp and the looped-over outer ends 22 of the wires which are bent back before the pinch sealing are pressed into contact with the sides of the pinch into which the tips may be sealed. The lamp may be capless or a cap having contacts may be slid over the pinch. The method may also be applied to double-ended lamps in which a single lead-in wire passes through each pinoh. Support wires for the filament may also be supported in the end 13.

Title: Improvements in hydrophilic compositions
IPC: G03C1/053
Filed: 1953-09-24
Abstract: A synthetic resin composition comprises a mixture of an aqueous dispersion of a naturally occurring hydrophilic colloid or a modified form thereof, and a hydrosol of a polymer obtained by the emulsion polymerization of a mixture of (a) an amide of an acid of the acrylic acid series, such as acrylamide, N-methacrylamide, and N-ethylacrylamide; (b) an acrylic acid ester such as methyl and butyl acrylates and methyl and ethyl methacrylates; and (c) a compound of the styrene type such as styrene, o-chlorostyrene and p-methyl styrene.  Polymerization may be effected using a persulphate catalyst and sodium lauryl sulphate as the dispersing agent.  The colloid may be gelatin, casein, wheat protein, or a modified form of zein, wheat gluten, casein or soy protein.  The dispersions may be used for the preparation of coatings for photographic purposes and for this purpose may contain barium sulphate, dyes and silver halides. Specification 648,927, [Group IV (b)], is referred to.
Patent GB-344842-A (GB)
Title: Improvements in and apparatus for the recovery of the energy transmitted to liquids in the conveyance of the same against high pressures
IPC: F01L25/08
Filed: 1929-08-30
Abstract: 344,842. Pumping liquids. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.- (I. G. Farbenindustrie Akt.-Ges.; Frankfort-on-Main, Germany.) Aug. 30, 1929, No. 26449. [Class 102 (i).] A method of utilizing the energy of liquid which has been conveyed against high pressure consists in transmitting the pressure of the liquid to a second liquid by means of a piston or membrane, and conveying the second liquid against the high pressure. Apparatus for the purpose may comprise one or more pistons K to which the pressure liquid from the chamber A passes through a rotary valve H, the piston on the pressure stroke forcing the second liquid in the cylinder Z through a valve D into the chamber A. At the end of the stroke, the valve H is operated to release the pressure liquid through a pipe L, and the piston is returned by the second liquid entering the cylinder Z through a valve S. This liquid may enter under a pressure head, or it may be forced in by a pump P. In another form, the admission and exhaust of the pressure liquid are controlled by two lift valves operated by hydraulic pistons. In another form, the valves and their operating pistons are coaxial, and the valves are combined lift and piston valves. When a diaphragm is used instead of the piston K, the valves may be operated electrically. Reference has been directed by the Comptroller to Specification 330,106, [Class 135, Valves &c.].
Patent GB-371464-A (GB)
Title: Improvements in or relating to methods of and apparatus for recording sound and in sound records
IPC: G11B7/00
Filed: 1931-06-04
Abstract: 371,464. Optical sound - recording apparatus. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London.-(Bell Telephone Laboratories, Inc. ; 463, West Street, New York, U.S.A.) June 4, 1931, No. 26467/30. [Class 40 (ii).] Relates to photographic sound-recording apparatus of the kind in which the record is made by light from a lamp which is controlled by an alternating current varying with the sound and by a direct current derived from a rectifier to which the alternating current is applied. According to the invention, a smoothing circuit comprising a condenser and resistance network is associated with the rectifier (which is preferably of the thermionic valve type) so that the direct current bias applied to the lamp varies gradually with the amplitude variations of the sound. The smoothing circuit preferably has a time constant greater than one period of the lowest sound to be recorded. In the arrangement shown, a microphone 1 is connected to an amplifier 2, the current from which controls a valve 4, in the output circuit of which are arranged two transformers 5, 6 (or a three-winding transformer). The output of the transformer 5 is supplied to a resistance 9, on which is a movable contact tapping off a portion of the voltage. This is applied, through a network consisting of a high resistance 13 shunted by a condenser 14, to the grid of a valve 12. An adjustable negative bias is provided by a battery 16 and potentiometer 15. The anode 19 of the valve 12 is connected through a resistance 20 to a lamp 21, by which the record is made on a film 25, the lamp being also connected through the secondary winding of the transformer 6 to a battery 22, which is in series with a battery 8. A direct current from the batteries 8, 22 is thus supplied through the valve 12, the current passing through the lamp 21 and varying with the amplitudes of the sound being recorded. In the absence of sound, the bias on the grid of the valve 12 and the voltage of the battery 22 are so adjusted that the light from the lamp 21 is at a minimum, which preferably should produce an impression at the lower end of the region of correct photographic exposure. The voltage of the batteries 8, 22 in series is preferably adjusted to be slightly above the ignition voltage of the lamp. The instantaneously varying sound-modulated current produced in the secondary of the transformer 6, is superimposed on the direct current supplied to the lamp, and thus the emitted light varies both with the instantaneous variations and with the envelope of the volume variations of the sound. Specification 361,907 and 363,117 are referred to.
