Title: Improvements in methods for the production of composite images
IPC: G03B15/12
Filed: 1935-12-21
Abstract: 467,609. Photographic processes. PLANSKOY, L. Dec. 21, 1935, No. 35486. Convention date, Dec. 21, 1934. [Class 98 (ii)] Composite photographic images are produced on a sensitive emulsion which has been preliminarily treated e.g. by weak solutions of phenosafranine, tolusafranine, acryptol yellow or green, to facilitate the photochemical destruction of a latent image, by destroying by a second kind of light a determined region of a latent photographic image produced by a first kind of light, forming another latent image in this region, and developing the resultant image in the sensitive emulsion. In the first example, a latent positive image of a landscape is produced on the film by suitable lighting, and is then exposed to red light through the negative of the subject. This destroys the latent image in the region corresponding to the subject, which region is again exposed through the negative to blue light. The emulsion is then developed to obtain the composite image. In a second example, the subject is placed before a monochromatic e.g. blue, background and two negatives are taken, one the ordinary direct negative a, Fig. 1, without a light filter, and the other, the selected negative b through a filter e.g. orange yellow, complementary to the monochromatic background yielding the negative of the subject on a transparent background. The arrangement for producing the composite picture is illustrated in Fig. 1 and comprises guideways 2, 3 for receiving the negatives a, p and a positive plate of the landscape, respectively, and a guideway 4 for the sensitive element. Optical devices 5, 6 and a mirror or prism 1 combine the images. The sensitive film is exposed first to blue light through the negative b and then exposed to red light through the negative a yielding a latent image as in Fig. 4. The film is then exposed to red light through the landscape positive, destroying the latent image at certain portions to form a latent positive image of the landscape. Finally the film is exposed to blue light through the direct negative a and developed. In a modification there is formed on another sensitive film two intermediate images c, d, Fig. 7, one c obtained by exposing a uniformly exposed area of the sensitive film to red light through the negative a, and the other d by exposing another image area of the same film to blue light through the negative b. The sensitive film carrying a latent image of the background is then exposed to red light through image c, again to red light through image d, and then to blue light through image c. The method is applicable to kinematographic film.

Abstract: 926,397. Gyratory crushers. ARBRA VERKSTADS A. B. Oct. 3, 1961, No. 35680/61. Class 59. The lower crushing member 6 of a gyratory crusher is carried by a crank or eccentric extension 13a of a shaft 13 mounted in a sleeve 14 which is displaceable vertically in the machine frame 1 and is arranged to take up directly from the shaft, through a thrust bearing 19, the crushing load originating from the lower crusher member. The member 6 is carried by a conical body 7 which is mounted on the extension 13a through the medium of bearings 10, 11. The shaft 13 is mounted on the sleeve 14 through the medium of radial bearings 17, 18 and the axial bearing 19. Adjustment of the crushing pressure is effected by vertical movement of the sleeve 14 by pumping fluid through a pipe 23 to a space 22, the space also being connected to a pressure vessel so that the sleeve can yield to uncrushable objects. In operation, material is crushed between the fixed upper member 3 and the lower crusher member 6 as the latter is given an eccentric motion under the drive of the shaft 13 by a motor. Should the crushing resistances become excessive, the rotation of the member 6 on the extension 13a would cease.

Title: Improvements in or relating to the manufacture of welded tubes and the like and welding apparatus therefor
IPC: B21C37/08
Filed: 1935-12-31
Abstract: 465,904. Making tubes, containers, &c. DE HAVILLAND AIRCRAFT CO., Ltd., KELLY, C. H., and GROOMBRIDGE, A. T. S. Dec. 31, 1935, No. 36115. [Classes 83 (ii) and 83 (iv)] Angular bending ; uniting by fusion.-In a method of making welded tubes, drum containers, &c., preferably thin tubes of stream line section for aircraft, a flat metal sheet is first curved, then collapsed to fold over its upturned sides so that the edges are brought together and the seam is then welded, while the major portion of the collapsed sheet is immersed in a cooling liquid. The initial curving operation may be performed by rolls or by hand or power operated (e.g. hydraulic) dies 11, 12, the sheet having holes to engage locating pins 15 in the die 11, which also pass into holes in the die 12. The completion of the forming of the tube may be effected in two stages between separate pairs of dies. In the first stage the curved blank is bent to the form shown in Fig. 3 by dies 19, 20, the blank being located by pins 22 passing through holes therein so that a projecting lip 18 is formed on one edge. In the subsequent operation the edges are closed leaving the lip projecting not less than <1>/32" so that the subsequent welding operation may be performed without additional welding wire. Welding may be performed by an oxyacetylene blowpipe 37 mounted on a carriage 36 having rollers 38, 39 running on a guide tube 35 and driven by an electric motor 54 and gearing bv an endless cord or wire 53, which may be secured to the carriage by a screw clamp 52. The carriage further has a roller 41 engaging a tubular guide 42 suspended from the guide tube 35. The tube 28 is secured by lateral hinged clamps in a cooling-tank 29 with the portion in the region of the seam only projecting from the liquid so as to maintain the tensile strength of the tube during welding. The blowpipe is mounted in an adjustable clamp 48 carried by a rod 49 secured in an arm 51 which is pivotally secured to a rod 45 itself secured in an arm 44 pivoted in an arm 40 projecting from the carriage. The lower end of the rod 45 carries a grooved roller 47 which tracks along the seam in advance of the blowpipe. In the case of irregular workpieces appropriate pivotal connections are left free so that the tracking roller and blowpipe will follow the irregular seam. The work may be traversed instead of the blowpipe or in the opposite direction thereto. In making drum containers, longitudinal seam welding may be effected by traversing the jig or feeding the drum by a rotatable member past a fixed blowpipe. Circumferential seams may also be welded by rotating the jig or drum supporting elements about a different axis.

Title: An improved process for the purification of silica
IPC: C03C1/02
Filed: 1934-12-21
Abstract: Silica in the form of sand or the like is freed from iron present as an impurity by heating the sand in a solution of sulphuric acid (without the presence of hydrochloric acid) within a closed vessel in which no free oxygen is present in the atmosphere or dissolved in the solution, the sand being wholly immersed in the acid solution.  The sulphuric acid solution may also contain one or more reducing substances such as stannous or chromous salts, e.g. stannous chloride, hydrogen sulphide, hydrogen iodide, zinc or other metal, oxalic acid, formic acid, sodium formate and potassium ferrocyanide. The omission of such added substances is only permissible when the sand contains free iron.  The free oxygen present may be displaced by carbon dioxide by adding to the solution some crystallized sodium carbonate.  The vessel may be fitted with a pressure release valve and a valve for introducing sand without the admission of air.  The contents of the vessel may be heated to boiling.  The treated sand may be washed with an alkaline solution.  The first Provisional Specification describes also the use of nitric acid; and the use of a closed vessel is optional.

In a network comprising main and subexchanges in which tickative equipment is provided at the main exchange for all calls outgoing from the network, only the number of a calling subscriber within a sub-exchange is determined thereat, and the number of the sub-exchange concerned is determined at the main exchange by an identifier which serves also to identify calling subscribers directly connected to that exchange. As shown, groups of ring-cores H, Z, E corresponding to the hundreds, tens and units digits of subscribers' numbers are threaded selectively by loops such as AS211. When A.C. is applied to the relevant loop the groups of cores are effective in turn to control receivers S1. . .S0 and provide a record in a store SP. In the case of a line incoming from a sub-exchange the loop such as AS21 threads a core in one or more of the groups H, Z, E to identify the sub-exchange, and also a core VAK2 which results in the passage of a signal to the control unit ASK to stop the identifying operation when the appropriate number of digits (less than the full number) have been determined. In another embodiment, Fig. 4 (not shown), the identifying current flows over the c-wire instead of over the talking wires of the connection.
