Abstract: 1,095,877. Piezo-electric generators. S. H. NEWMAN. May 21, 1965 [May 25, 1964], No. 21606/65. Heading H2A. [Also in Division F4] In a gas-fueled lighter the gas is ignited by a spark produced by compression of a Piezoelectric cell 33. The lighter comprises a fuel e.g. butane reservoir 14 provided with a liftable valve 15 and nozzle 16 above which is situated a burner 18 comprising a gas-air mixer. The valve 15 is opened by a pivoted lever 29 operated by partially pressing down a lever 31, and the escaping gas passes through nozzle 16 to a passage 19 in barrier 18 where it mixes with air entering ports 21 and 22 forming a 1 : 9 fuel gas/air mixture. When the lever 31 is fully depressed the nozzle 16 enters the opening 21 thereby partially cutting off the air supply. The Piezo-electric element 34 is lined with insulation 35 and held in a U-shaped metal support 36 pivoted to the lighter casing on a pivot 37. When the lever 31 is depressed a cam 38 also carried on the pivot 37 bears against a plug 39 in contact with the element 34 and an electro-motive force is produced therein. The discharge from the cell is conducted to a spark gap 42 above the burner 18. A spring 43 returns the lever 31 to its normal position. In an alternative form of mechanism, Fig. 6 (not shown), the cell 34 is compressed between a support 47 and a press plug 39<SP>1</SP> by depressing the jointed ends of levers 49 and 50 by an overcentre cam 46 on a lever 44.

Abstract: 369,128. Recording or reproducing sound films. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Bedford, A. V. ; 4730, Lafayette Avenue, Merchantville, New Jersey, U.S.A.) July 29, 1931, No. 21649. Convention date, Aug. 4, 1930. [Class 40 (ii).] Relates to apparatus of the kind employing a photographic film 1 having several separate sound traces 8 recorded or reproduced in succession by an optical system which is moved transversely of the film from one trace to the next by means controlled from the film. According to the invention, the movement of a controlling-member 27 engaging gaps 24 or other irregularities in the margin of the film is amplified solely by mechanical means in order to effect the traverse of the optical system. In the apparatus shown, a carriage 16 carrying the optical system is urged to the right by a spring 34 and is retained by a ratchet-pawl 33 controlled by double toggle-levers 36, 40 which are collapsed, at intervals determined by the gaps 24, by the movement of the controlling member 27 which normally bears on the film. This movement causes a spring 30 to press the end 31 of a lever 29 against the link 40 thereby causing both toggle-levers to collapse and release the pawl 33. The carriage 16 then moves under the control of a dashpot until the pawl is re-engaged by the straightening of the toggle-levers effected by a tension spring 43. The film passes over a drum 11 of the form described in Specification 293,380, [Class 40 (ii), Phonographs &c.].

Abstract: 1,080,113. Infrared analysis. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 25, 1965 [May 28, 1964], No. 22116/65. Heading G1A. Powdered material is analyzed by bringing it into contact with the surface of a light guide, passing infrared radiation through the guide to make an angle greater than the critical angle with said surface and spectrally analyzing the light internally reflected from the surface. Since internally reflected light penetrates about one wavelength beyond the reflecting interface, it is subject to absorption by the powder, and spectral analysis of the light produces the usual infrared absorption spectrum for the powdered substance. The light guide may be a slab of Ge, Si or AgCl. A two beam system in which radiation from a source is switched to fall on a detector alternately directly and through the light guide may be used. Cigarette smoke may be analyzed by passing it into a chamber 11 where the smoke particles are given a positive charge by a corona discharge between electrodes 12 and 13 and deposited on the surface of the light guide 3 which is rotated by a motor M.

Filed: 1937-08-13
Abstract: 495,501. Oil engines. KAMMER, G. S. Aug. 13, 1937, No. 22359. Convention date, Aug. 28, 1936. [Class 7 (iii)] Fuel is delivered into air at low pressure contained in a chamber separate from the engine cylinder. At the end of the compression stroke compressed air is forced from the cylinder into the chamber and the mixture ignited by the heat of compression or by a sparking-plug ; the gases in the chamber are returned to the cylinder by reducing the volume of the chamber to zero. In the two-stroke engine shown in Fig. 1 the chamber is formed by an auxiliary cylinder 3 which communicates with a combustion space 16 in the cylinder through a tangential port 4 controlled by a port 5 in a sleeve carried by an auxiliary piston 2. After the scavenging stroke of the piston 1 has been completed the piston 2 is lowered over a fixed but adjustable plunger 7 to inject fuel from a space 10 through a nozzle 22 into air which has entered through the ports 4, 5. At the end of the compression stroke in the engine cylinder the piston 2 rises to bring the ports 4, 5 into register to admit compressed air into the cylinder 3 and combustion commences. Further upward movement of the piston 2 forces the gases in the cylinder 3 into the chamber 16. The piston 2 then remains stationary until the end of the scavenging stroke of the piston 1. In the modified construction shown in Fig. 2, the auxiliary piston 17 moves downwards at the end of the compression stroke of the piston 15 to admit compressed air through passages 18, 19 into the space 20. The piston 17 rises near the end of the working stroke of the piston 1 and delivers the gases through passages 19, 21 into the working cylinder.
