Title: Improvements in silencers for internal combustion engines
IPC: F01N1/02
Filed: 1934-07-31
Abstract: 442,438. Exhaust silencers. SALENIUS, C. G. T., 13, Tomtebogatan, Stockholm. July 31, 1934, No. 22313. [Class 7 (ii)] The silencer comprises a casing 10 connected to the engine exhaust at 11, the interior of the casing being in communication through a tube 15 with a closed chamber 14 which, in a modification, may be located outside the casing. The open end of tube 15 faces the oncoming gases, but is shielded from the direct gas flow by one or more screens 16, 18 which materially restrict the passage for the gases. The effect of such screens is stated to set up ejector action and vortex motions, with the result that low pressures are created in the chamber 14 which cause gases to enter that chamber during high-pressure impulses. In a modification, the tube 15 is extended to join the truncated end of the conical screen 16.

Abstract: 388,373. Optical sound-reproducers. NUBLAT, R. L. A., 17, Boulevard de Grand- Chene, Le Parc St-Maur, Seine, and SOC. D'ETUDES POUR L'EXPLOITATION DES BREVETS NUBLAT, 56, Rue de Paradis, Paris, both in France. Aug. 17, 1931, No. 23142. [Class 40 (ii).] Apparatus for the optical reproduction of sound from a record of constant width and density includes an opaque screen which limits the reproducing light beam so that the band of light impinging on the photo-electric cell is limited on one side by the straight edge of the screen and on the other side by one of the sinuous edges of the record track. A sound record 3, Fig. 1, of constant width and density is recorded on a film by removing a portion of an opaque layer 2 by means of a transversely-vibrated cutting tool. Sounds are reproduced directly from this film by interposing in the path of the reproducing light beam an opaque screen 9 having a straight edge so that the beam which passes through the film to impinge on a photo-electric cell will vary in width in accordance with the sinuosities of one side of the record track 3. The light beam is passed through an optical system which widens it so that the adjustment of the screen 9 is facilitated. In the case of a combined sound and picture record film, wherein the pictures occupy the whole width of the film, it is possible to coat the back of the film with a layer of material transparent to light but impermeable to certain rays outside the visible range. By engraving this layer mechanically a sound record may be obtained which does not affect the picture record but may be reproduced by a photo-electric system responsive to the rays of the non-visible range.

Abstract: 360,850. Television. COMMUNICATIONS PATENTS, Inc., 60, Broadway, New York, U.S.A. Aug. 7, 1930, No. 23707. Convention date, May 31. [Classes 39 (i) and 40 (iii).] In television an electric arc, moving under the influence of a magnetic field, scans an object from a plurality of angles for stereoscopic reproduction. In one system, Figs. 1 and 4, the arc is initiated at the gap 70, and moves along the electrode system 5, 6, under the action of a magnetic field produced by a winding 71. Light from the arc scans the object 0 alternately through pinholes 10, 11, a screen 1 dividing the electrode system into two portions. Light reflected from the object O falls on a cell 60, Fig. 4, or on two cells 13, 14, Fig. 1. The two cells 13, 14 are made alternately operable by biasing the amplifiers 15, 16, through reversely connected transformers 26, 27, fed with alternating current from a source 25. The amplifiers 15, 16 are connected in the transmission circuit through transformers 22, 23. Alternatively the cells 13, 14 may be made alternately operable by scanning the object alternately with two differently coloured radiations, e.g. by placing colour filters in pinholes, each cell being responsive to one colour either intrinsically or as a result of colour filters placed before them. The distance between the pinholes 10, 11 may be adjustable. In a further modification, the arc is driven over systems of the form shown in Figs. 5 and 6, so as to scan the object from two places, this being stated to result in stereoscopic reproduction, The arc may be driven along a path 93, Fig. 7, between wide electrodes 91, 92, by two magnetic fields at right-angles so as to scan the object from a plurality of different planes. The receiving screen comprises an electrode system similar to and longer than that at the transmitter. The system is synchronized as described in Specification 360,470, and the receiver and transmitter may alternate in function to provide a two-way system as described in Specification 360,470. The system may be adapted for colour reproduction as described in Specification 358,183. Specification 360,941 also is referred to.
