Title: Improvements in or relating to plant generating hot combustible gases
Inventor: EDMONDSON PHILIP DAVID
IPC: F02C7/10
Filed: 1949-10-05
Abstract: 684,028. Gas-producers. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Oct. 4, 1950 [Oct. 5, 1949], No. 25632/49. Class 55 (i). A gas-producing plant comprises two gas-producing chambers or zones which are arranged with regenerators so that the hot product gas of the operative producer heats a regenerator for heating the blast gas of the other producer when it is made operative. As shown, two gas-producers 1, 2 are alternately connected with the fuel supply 3 and are in series with regenerators 5, 6 and filters 7, 8. Air, or other blast gas such as oxygen or steam or a mixture of oxygen and steam, is supplied through valve-means 10 described below, to one of the ducts 9, and is heated by passing through the regenerator 5 or 6 and through the inoperative producer 1 or 2 to the conduit 4. On admission to the operative producer, the blast is at a temperature sufficiently high for gasification. The hot gases from the operative producer pass through the corresponding regenerator to the outlet passage of the valve 10. In a modification, instead of an interconnecting blast conduit 4, the producers are connected together at their outlets, so that the gas produced passes through the idle producer before passing to the filter and regenerator. The valve means 10 comprise in and out ducts 21, 22, for air and producer gas respectively, connected to regenerators 23, 24. The air duct 21 may be connected either to the regenerator 23 or 24 by adjustment of flap valves 25, and the producer gas outlet may be connected to either of the regenerators by adjustment of the flaps 26. The flaps 25, 26 are operated simultaneously.

Title: Photographic material for making half tone records
IPC: G03F5/00
Filed: 1953-09-19
Abstract: 748,720. Sensitive material for photomechanical procedure. KODAK, Ltd. (Eastman Kodak Co., Yule, J. A. C., and Maurer, R. E.). Sept. 20, 1954 [Sept. 19, 1953], No. 25919/53. Class 98 (2). A self-screened material for producing halftone images suitable for preparation of intaglio printing-plates comprises a support carrying a silver halide emulsion layer having a half-tone pattern of undulating sensitivity as of a contact screen, the areas of lower sensitivity having been produced by desensitizing treatment, and areas of higher sensitivity situated at the centres of squares constituting the pattern having latent images in the form of Maltese Crosses with the ends thereof in the middles of the sides of the squares. These latent images act as partial pre-exposure areas to give increased sensitivity in the shadows when the material is exposed in a camera to make a half-tone negative, as further described in Specification 699,659, and are of Maltese Cross formation so that ridges for supporting the doctor blade may be provided in the intaglio printing plate produced from such negative. Fig. 1 shows a form of apparatus for making the material in which desensitizing is effected by Clayden exposure treatment, wherein a high contrast film 1 is exposed behind a ruled cross-line screen 2 to a flash from lamp 9 through lesns 10, diffusing sheet 11 and the apertured plate 5 of Fig. 2 with interposition of a semi-transparent or hinged mirror 12. Before or after this desensitizing exposure the film 1 is exposed also to lamp 17 through diffusing layer 33 and the apertured plate 4 of Fig. 3 to produce the Maltese Cross formation of latent images. Data concerning screen ruling and distance, aperture spacing in the apertured plates, aperture to film distance and exposure times for the Claydon desensitizing and the latent image exposures are provided in the Specification whereby the desired screen formation will result, such formation being somewhat indicated by the dotted lines 20 of Fig. 2 which indicate the relative location of the latent image exposures through apertures 21 of Fig. 3 to the exposure apertures 7 of Fig. 2, and by the nine black dots 22 of Fig. 3 which indicate the relative positions of the desensitizing apertures 7 and thereby the highly desensitized corners of the square pattern elements. Figs. 6 and 7, not shown, indicate a corresponding but less preferred method of making the sensitive material in which desensitisation is effected by use of a solution as of hypo. Exposure of the material to a continuous tone image and processing leads to a structure suitable for making an intaglio half - tone gravure. Specifications 474,911 and 544,033 also are referred to.

Abstract: 599,851. Gearing utilising universal joints. SUPPANIC, G. O., and LACHMANN, G. V. Dec. 29, 1944, No. 26085. [Classes 80(i) and 80(ii)] The relative angular velocity between driving and driven shafts connected by a universal joint is varied by providing means to vary the angular relation between the two shafts which means at the same time causes rotation of the driving shaft through the reaction thereof with a fixed abutment. In Fig. 1 a driving shaft A22 is coupled by a universal joint comprising forks A223 and A53 and a cruciform member A57 to a driven shaft A20. The shaft A22 is supported in a bearing A33 in a yoke member A30 pivoted at A31 and A32 to a fixed casing A35 and is adapted to be rotated through a gear A50 meshing with a fixed gear A51 on angular movement of the yoke A30 by an actuating member A52. A rotary movement of driven shaft A20 is thus obtained from the rotary movement of shaft A22 modified according to the instantaneous angular relation between the two shafts. In a modification of this arrangement an annular ring is arranged between, and pivotally connected to, the universal joint and one of the shafts, the angular position of which may be varied independently to give a further variation of the relative velocity. In another modification the cruciform member is formed of two parts movable relatively longitudinally so that one pair of pivots can be offset with respect to the other pair to give the further independent variation of the relative velocity. In another arrangement, Fig. 6, a continuous oscillating movement is imparted to the yoke D30, supporting the shaft D22 of the joint D223, D57, D201, from a continuously rotating shaft D52 by means of a crank and connecting rod D58, D59 so that a continuous oscillating motion of driven shaft D20 is obtained, the velocity ratio of which relative to the driving shaft D22 varies continuously.
