Filed: 1929-07-16
Abstract: 336,613. Kucharski, S. July 16, 1929. Automatic apparatus. - Apparatus for taking a series of photographs is provided with means for changing the illumination of the object photographed as the exposures are made. The different illumination may be produced by alternative bulbs or by movement of the bulbs to different positions. In the form shown, a series of lamps 16 - - 19, which illuminate a sitter on the seat 56 from different directions, are connected up through a controller switch 7 driven by the main shaft 35 which operates the camera. The sitter may be protected from glare by gauze curtains, and permanently lit lamps 25 may also be included for frontal illumination. For softening effects, the lamps in use may be kept in motion during exposure by mounting the carrying frame 5 on crank arms also driven from the main shaft. The shutter diaphragm may also be varied by a cam 36. A beaded frame 57 is illuminated by a rear lamp 4, and in conjunction with a mirror 59 enables the sitter to pose himself. A series of numbered mirrors 61, 62 .. enable the sitter to look in the direction appropriate to the illumination. The photographs may be printed on one card. In Fig. 6, a to k represent a series of ten photographs which may include poses of the sitter under each of five different lighting arrangements.

Abstract: 387,389. Apparatus for making boots ; methods of lasting. BRITISH UNITED SHOE MACHINERY CO., Ltd. and BATES, A., Union Works, Belgrave Road, Leicester. Aug. 6,1931, No. 22259. [Classes 17 (i) and 17 (ii).] A method of producing a shoe with an outturned upper comprises the steps of (a) securing the sole temporarily to cover the tread of a last or form, (b) conforming the upper to the last, (c) holding the upper in position by a clamp portable with the last to retain its shape, and finally, (d) presenting the whole as a unit to a machine for fastening the margins of the sole and upper together. A preferred form of apparatus is shown in Fig. 1, which is a modification of that discussed in Specification 25921/11, [Class 17 (i), Boots and shoes, Apparatus for making &c.]. The device comprises standards 12 between which is an arm 14 pivoted at 16 and carrying the lower jaw 18 of a pair of jaws, the upper 20 pivoting at 22 on the lower jaw. An operation arm 24 on the upper jaw carries a sole rest 28. This arm may be increased in length 29 and connected to a pedal. Depression of the arm 24 closes the jaws against a spring 30. An adjustable stop 32 limits downward movement. Yield of both jaws, to permit some movement, is provided by a strong spring 34 surrounding a rod 36 and connected to the lower end of the arm 14 so as to hold it against an adjustable pin 40. The jaws grip the upper at either side of the toe, Fig. 2. Each jaw has two separated gripping portions, those for the upper jaw being shown at 44, 46. The gripping faces are not located in each jaw in a single plane, but are downwardly and outwardly inclined, Fig. 1. The lower jaw 18 is recessed to allow the toe end of a sole to pass freely upward. The upper jaw is also preferably recessed but in that case has a bridge piece 48 riveted thereto 49. The bridge piece may be yieldingly mounted and serves to wipe down the toe end of an upper as the device is rocked by the arm 24. A retarding action of the bridge piece is provided by a plate 50, Fig. 3, carried by a bifurcated lever 52 pivoted at 22 and connected by a light spring 54. The toe end of the shoe is inserted as at 62, Fig. 3. The device is rocked by the arm 24 and wiping performed. After this an upper clamp 56, Fig. 1, preferably as described in Specification 376,256, holds the upper stretched or even further stretches it. A pincer device as above or a simpler form as in Specification 25921/11, may be mounted on the usual tool and worktable of a stitching mechanism.

Abstract: 1365445 Propellants IMPERIAL CHEMICAL INDUSTRIES Ltd 4 April 1973 [12 May 1972] 22340/72 Heading C1D [Also in Division F3] A caseless propellant charge for nail guns is prepared by subjecting a porous propellant composition to a pressure of at least 1,000 psi. Pressures up to 40,000 psi. can be used. The composition is compressed in bulk or sheet form, or, is divided into quantities appropriate for individual charges and compresed and shaped in a mould. The individual quantities are produced by extruding a mixture of propellant, solvent and filler through a die; drying off the solvent; cutting the composition into individual lengths; and leaching out the filler to produce voids in the composition. The composition can be extruded through a multi-pin die to produce longitudinal passages in the propellant charges. The propellant consists of nitrocellulose; nitrocellulose/nitroglycerine; or nitrocellulose/nitroglycerine/nitroguanidine. A suitable primer comprises lead azide, lead styphanate, tetrazene, RDX or PETN. The lead styphanate can be mixed with ground glass and gum arabic and applied in the form of a slurry to a cavity in the propellant charge. The tetrazene may likewise be applied as a slurry in nitrocellulose solution and covered with a coating of collodion.

Abstract: 364,088. Discharge lamps. LEDERER, A., Hermesvilla, Vienna. July 25, 1930, No. 22497. Convention date, July 30, 1929. [Class 39 (i).] - In an electric discharge lamp containing a filling of a rare gas and co-operating electrodes, one or each of which is adapted to be heated indirectly to electron-emission temperature, the size of the bulb, the pressure of the contained gas, and the size, shape, arrangement and spacing of the electrodes are such that at the voltage at which the lamp is adapted to be used the cathodic light is caused to develop and expand a considerable distance around the hot electrode, or each hot electrode, as a bright aureole, and to predominate, in the total illumination given by the lamp, over the positive column light. For use on direct current the lamp has a single hot electrode and a small anode, while for alternating current both electrodes are hot and of the same size. In an example, using a globe or similar shaped bulb, the diameter of the bulb is about three times the distance between the electrodes which are about 50 mm. apart, the filling consisting of neon at a pressure preferably between 1 and 5 mm. of mercury, and the applied voltage being less than 20 volts. The electrodes are tubular, from 2 to 3 mm. in diameter, and between 1 and 2 cm. long. The shape and dimensions of the bulb may be such that the bulb wall corresponds substantially to the outer limit of the luminescence which is developed within the bulb. A cylindrical bulb may be used, and the gaseous filling may consist of one or more of the gases helium, neon, argon, krypton, and xenon.
