Colour photography, screens and screen plates for.-A multicolour screen, applicable to flat or roll films or to glass plates, is built up by cementing together two supports each of which carries different component colour elements of the screen. The sensitive layer may be applied on one side of the built-up screen, and a non-curling colloid layer may, in the case of thin films, be applied on the other side. The components in the case of flexible films are formed upon two thin films; and, in the case of thick films or glass plates, upon a thin film and a thick film or glass plate. The screen patterns may be of line, dot, or other form. It is stated that, in the case of line patterns, the lines on one component support may be parallel to, or may cross at 45<b> or at 90‹, the lines on the other component support. The components are united by applying adhesive to each, superimposing them face-to-face, back-to-back, or face-to-back, and applying heat and pressure.

Abstract: 836,906. Transfer moulding machines. HILL, R. M., and GRAY, G. E. [trading as GRAYHILL.]. March 18, 1957, No. 8779/57. Class 87(2). An automatic horizontal plastic moulding machine includes in combination a fixed mould block assembly 15 and a movable mould block assembly 16, each having vertical parting faces and providing when closed a mould cavity 34, a transfer cylinder 24 connected to the fixed mould block assembly 15 and communicating with the cavity, feeding means 70 for providing moulding material in the cylinder, and transfer piston 25 movable in the cylinder for forcing the material into the cavity. The feeding mechanism 70, Fig. 11, which has a feeding tube 71 through which the material in powder or pulverised form is fed to the transfer cylinder 24 by means of plunger 92, is mounted for swinging movement on arms 74, 75. Arm 75 is pivotally connected to the frame at 78 and includes a portion 79 connected to the feeding mechanism 70 and a portion 80 having a U-shaped recess 81 for receiving a roller 82 connected to the transfer piston 25. Consequently when the piston 25 moves forward, the feeding mechanism swings upward to the dotted line position. The plunger 92 does not move as far as the outlet 72 of the feeding tube and after each movement one charge of material remains in the tube to be forced into the transfer cylinder by the next feeding operation. A heating coil 96 may be positioned about the tube 71 to preheat this remaining charge. As shown in Fig. 4, both mould block assemblies 15, 16 are provided with knockout pin assemblies, each of which includes a piston 63 with a head 64 fitted with knockout pins 65 extending through openings 35 into the cavity 34. These pins may also be used to form projections or recesses on the moulded article. If desired, plastic articles with metal inserts may be moulded, the inserts being cut by dies attached to the moulds from wire fed into the cavity from reels. The various moving parts of the machine are operated by compressed air cylinders electrically controlled by interlock switches with a timer to automatically provide the required sequence of operation.

Filed: 1944-05-09
Abstract: Amidines of the general formula <FORM:0577478/IV/1> wherein R represents hydrogen or an alkyl or aryl radical, R1 represents an alkyl or aryl radical and R2 and R3 either represent alkyl or aryl radicals or one represents an alkyl or aryl radical and the other a hydrogen atom, are produced by reaction of an amine of the general formula <FORM:0577478/IV/2> with a sulphonic ester having the general formula <FORM:0577478/IV/3> R, R1, R2 and R3 having the significance above and X being a hydrocarbon radical.  The requisite sulphonic esters may be prepared (a) in general, by reaction of an N-substituted carboxylic amide with an aromatic sulphonyl halide, or (b) when R and R1 represent alkyl or aryl radicals, by reaction of a sulphonyl halide with a ketoxime having the general formula R.C(=N.OH)R1.  In examples: (1) benzenesulphonyl chloride is added with stirring, to formanilide in dry pyridine at -10 DEG  C., the product is heated with aniline to produce N.N1-diphenylformamidine hydrochloride and the free amidine is obtained by adding dilute caustic soda; (2) acetanilide is stirred with chloroform and benzenesulphonyl chloride in dry pyridine prior to introducing aniline in chloroform dropwise and, after standing, precipitating N.N1-diphenylacetamidine from the washed aqueous extract by basifying with ammonia; (3) benzanilide and benzenesulphonyl chloride are heated together in pyridine, aniline is added and heating continued, producing N.N1-diphenylbenzamidine hydrochloride from which the free amidine is obtained as in (1); (4) toluene-p-sulphonyl chloride is heated with N-methylbenzamide in dry pyridine prior to introducing aniline, further heating, dissolving in alcohol and isolating the corresponding amidine by adding 4N. sodium hydroxide; (5) diphenylketoxime benzenesulphonate and diethylamine are refluxed together in dry benzene and the corresponding amidine is isolated by extraction with dilute hydrochloric acid, and precipitation with ammonia; (6) toluene-p-sulphonyl chloride in acetone is added, with stirring, to methyl phenyl ketoxime in N. sodium hydroxide cooled below 0 DEG  C. and the product is benzene-extracted, washed and evaporated to dryness in vacuo at room temperature and the residue, in benzene, is treated with aniline, warmed to initiate reaction and then boiled, the oil which separates being dissolved in aqueous alcohol and N.N1-diphenylacetamidine liberated therefrom by adding ammonia.

Abstract: 494,417. Filters. STOTHERT & PITT, Ltd., and SMITH, S. R. March 25, 1937, No. 8845. [Class 46] A strainer basket 10, Fig. 1, divided into two parts by a partition 11 is rotatably mounted in a casing 1 so that liquid from the inlet 2 can enter one part 12 and pass outward through the strainer to an annular space 14 and outlet 3, while the other compartment 13 is in communication with a sump 9, fitted with a filter 20 and connected through a three-way valve 19 and a pipe 18 to a source of low pressure, so that the compartment 13 is cleansed by strained fluid from the space 14 passing inwardly and carrying separated matter into the sump. Liquid passing through the filter 20 can be returned to the system and separated matter is discharged from the sump through a cock 91. The filter 20 is cleansed by passing liquid under pressure reversely therethrough, as from the space 14 through a connection 181, when the cock 9<1> is open. In the modified form of apparatus shown in Figs. 3, 4, and 5, the interior of the strainer is divided into parts by an arcuate plate 22 with flanges 23, 24, the flange 24 making scraping contact with the strainer as the latter is rotated. The space between the plate and the strainer communicates with a sump 9 fitted with a semicylindrical filter 20. Filtered liquid is discharged from the sump through a plug valve 29 and passage 31. When the plug is turned, the contents of the sump are discharged through a passage 30, liquid to flush the sump being admitted through a port 38 from the space 14. The port 38 is opened by means of an arm 39 attached to the plug, which is operated by a spindle 32.

Abstract: 915,582. Roofs and floors; preformed building slabs. MAXWELL, R. H. June 14, 1961 [March 14, 1960], No. 8975/60. Classes 20 (4) and 87 (1). A method of constructing floors or roofs or preformed sections thereof comprises positioning one or more preformed foamed synthetic resin sheets beneath the floor or roof joists, forming a foamed mass of synthetic resin in situ on said sheet or sheets and wholly or partly around said joists to form an integral structure therewith and, when the foamed mass has set, applying concrete to the surface of the foamed mass. Preferably the sheets are secured to the joists by means of an adhesive. If the joists are solid, locating means are secured to the sides to key with the foamed mass, and the foamed mass may extend slightly above the top of the joist level. A pattern of channels may be formed in the surface of the foamed mass by laying a grid member on the mass before it has set to form strengthening ribs on the undersurface of the concrete. The concrete may be sprayed or flowed over the top surface of the cured foamed mass. The mass may be produced from a phenol-formaldehyde or a polyurethane resin. The method may be used for floors and flat or low-pitched roofs. For a steeply-pitched roof the method may be applied to the manufacture of preconstructed roof sections.
