Abstract: 516,724. Spray producers; liquid fuel burners. GARNER SUBMICRON ATOMIZERS, Ltd., GARNER, W. R., and GARNER, A. R. May 30,. 1938, No. 16155. [Class 69 (iii)] [Also in Group XI] A liquid fuel burner or liquid atomizer comprises a nozzle in which a mixture of the liquid and air or other gas is first given a swirling movement and then caused to pass through a restricted passage as a film into a chamber formed with impact surfaces and a discharge outlet. In the form shown in Fig. 1, compressed air and liquid fuel supply connections 28, 35 screwed to a block 4 are connected by passages 27, 34 to a conical chamber 26 from which a. pipe 3 leads to a nozzle 6 mounted on a pipe 2 surrounding the pipe 3. The nozzle 6 is fitted internally with a member 5 formed with a conical head 8 and a conical recess 7. The mixture issuing from the pipe 3 enters the recess 7 and passes through helical or otherwise curved channels 15 to the annular chamber 14 surrounding the head 8. From the chamber 14 the mixture passes through a restricted annular passage to impinge on the channelled inner surface 9 of the nozzle and then issues as a finely swirling mist or spray through a central orifice 11 which is flared at both ends. The fuel supply may be regulated by means of a needle valve 31 having a flat face 32. The valve 31 may be unscrewed to allow the removal or blowing-out of solid matter blocking the supply channels. Fig. 2 shows another construction in which the spreader member 5 is formed by a helically-grooved cylindrical rear portion 37 connected by a conical portion 40 to a cylindrical portion 41 formed with a V-shaped peripheral channel 42 connected by tangential grooves 44 to a central recess 43 surrounding the boss 45 on the nozzle 6 in which the discharge orifice is formed. The nozzle 6 is externally threaded to carry a ring 51 on which is mounted a perforated cylindrical flame cowl 52. In a modification, the member 5 is pressed against the rear surface of the nozzle 6 by a spring and is formed on its rear surface with a valve regulating the mixture discharge from the pipe 3. In another construction shown in Fig. 5, a mixture of fuel and air are supplied through an inlet channel 74 in the atomizer body while a gas such as oxygen is supplied through an inlet channel 75 to a channel 79 in the member 5 discharging into the cavity 43 so as to minimize the danger of explosion. The nozzles may be arranged in line or in clusters and their impingement surfaces may be undercut. The projecting parts and restricted passages may be duplicated or triplicated to produce finer atomization.

Title: Improved method and apparatus for recording and reproducing moving pictures and accompanying sound
IPC: G03B31/00
Filed: 1931-06-04
Abstract: 379,737. Combined sound and picture records ; recording and reproducing. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Coffman, J. W.; 33, 86th Street, Jackson Heights, New York, U.S.A.) June 4,1931, No. 16242. Convention date, June9,1930. [Classes 13 and 40 (ii).] Pictures and accompanying sound are recorded upon or reproduced from a film by passing the film successively before a picture-recording or projecting lens system and a sound-recording or reproducing means, and in delaying the transmission of the sound waves or the electric currents corresponding thereto, so that the picture and its accompanying sound are recorded in line laterally on the film or are reproduced simultaneously. As applied to a recording system, Fig. 1, the sounds impinging upon a microphone 10 are amplified and passed through a conduit 14 of an acoustical delay device 12, after which they are reconverted into electrical oscillations which are amplified and control the intensity of a lamp 18. The light from the lamp 18 records the sounds on a film 22 within a combined picture and sound-recording camera 20, the pictures being photographed through a lens system 27. The film passes from the picture lens system to the sound recorder and the delay period in the transmission of the sound is controlled by regulating the length of the conduit 14 to compensate for the time taken by the film in passing from the picture gate to the sound recorder, so that the pictures and sound are recorded in line laterally on the film. A combined sound and picture film so recorded is reproduced as shown in Fig. 2 by being passed first through a sound reproducer 40 and then through a picture projector 50, the reproduced sounds being transmitted through the conduit 63 of a delay device 61. The delay device 61 is adjusted to compensate for the time taken by the film to travel from the sound reproducer to the picture gate, so that the pictures and accompanying sound are reproduced simultaneously. Fig. 3 illustrates a record film produced by the method of Fig. 1. Cutting and splicing can be effected in a straight line across the film. An electrical delay circuit for the sound waves may be employed instead of a mechanical delay system.

Title: Sheet materials comprising coated polyethylene
IPC: C08J7/056
Filed: 1957-05-23
Abstract: 868,924. Coated polyethylene film. LOEWE PAPER CO. May 23, 1957 [May 24, 1956], No. 16424/57. Class 140. Sheet material comprising coated polyethylene is prepared by extruding polyethylene to form a film and applying a hydrophilic coating to a surface of the hot film immediately on its emergence from the extrusion orifice. The hydrophilic substance may be starch, carboxymethyl cellulose or a protein e.g. gelatin or casein. The polyethylene film may be united with a backing of another material, e.g. paper or boxboard, at the side remote from the hydrophilic coating. The backing material may be continuously extrusion-coated with polyethylene and the hydrophilic coating is continuously applied to the polyethylene as this is applied to the backing material. As shown, paper 6 is fed into a nip formed between roller 7 and cooling drum 10. Molten polyethylene 8 is continuously extruded in the form of a film into the nip so that the paper becomes extrusion-coated with the polyethylene at the nip. A polar, e.g. aqueous adhesive solution 12 which is to form the hydrophilic coating, is fed by means of rollers 13 to the surface 14 of the cooled drum 10. The solution passes underneath radiant heaters 15 so that water is evaporated from it. The adhesive is transferred to the hot-extruded polyethylene film as it is being combined with the paper in the nip, the paper carrying the polyethylene and hydrophilic coatings being removed from drum 10 by roller 16.
