Filed: 1948-02-11
Abstract: 641,833. Ironing-presses. PROSPERITY CO., Inc. Feb. 11, 1948, No. 4057. Convention date, Aug. 16, 1946. [Class 138 (ii)] In a sleeve-pressing machine with opposed pressing elements 11, 12 having relative opening and closing movements, an envelope 22, 23 for receiving a sleeve is carried by both pressing elements and includes a member 22 having opposed portions arranged in heat conducting relation to the pressing faces of the pressing members and with an intermediate fold portion 24 connecting like edges of the opposed portions. Figs. 2 and 7 show a press having two sets of pressing elements 11, 12 arranged for pressing both sleeves of a shirt simultaneously. The movable elements 12 are carried by arms 13 pivotally mounted on a standard 14, each member being opened by a spring 21 and closed by a stem 18 which is moved by a compressed-air-actuated diaphragm 17. A table 1 which is movable both vertically and horizontally carries two forms 2 on which the sleeves of the shirt are placed, the forms 2 being movable to a position between the pressing members 11, 12. The table 1 can move horizontally by means of pivoted links 5 which are carried by a vertically movable cross-slide 8 on a pedestal 10. Attached to each pair of pressing elements is the envelope, Fig. 3, between which the form 2 is received. Each envelope comprises a member 23 which is slidably fixed to the pressing element 12 by pins 44, 45 engaging slots in the envelope and a member 22 which is fixed to the other pressing element 11 by a lip 46. The member 23 has a folded portion 25 for ironing one edge of the sleeve and is connected by a linkage system 27, 31, 36, 39 to the cross-slide 8 on which the table 1 is supported so that when the table is raised to enable the armhole part of a long sleeve to be ironed the member 22 is moved laterally to the left as shown in Fig..2, to accommodate the greater width of this part of the sleeve. The member 22 comprises two leaves resiliently connected by a fold 24 which is inclined to conform to the tapered edge of the form 2 for ironing the tapered side of the sleeve. In use the cuff part of a sleeve is ironed first. To iron the remainder the table 1 is then raised and through the linkage moves the member 23 to the left to accommodate the greater width of the form and at the same time the pressure of the tapered edge 24 on the form 2 swings the table to the left on its links 5 so that the sleeve continues to engage the edge 25 of the member 23.

Title: Improvements in or relating to reforming process and catalyst therefor
Inventor: CIAPETTA FRANK GEORGE
IPC: B01J21/08
Filed: 1951-02-23
Abstract: Petroleum distillates (especially gasoline fractions) are reformed to products having high anti-knock values by treatment with a catalyst comprising platinum or palladium and a silica-alumina cracking component having a surface-area of about 10-65 square metres per gram (see Group III).  Reforming is carried out at a temperature of 600-1000 DEG  F., a pressure of 100-1000 lbs. per square inch, an hourly liquid space velocity of 0.1-10, and in the presence of 1-20 mols. of hydrogen per mol. of hydrocarbon.  The maximum isomer yields obtained are substantially independent of temperature so that the temperature may be raised to increase the formation of aromatic hydrocarbons, and higher hydrogen partial pressures may be used to reduce demethanation and carbon formation.  The process may be of the fixed, moving, or fluidized bed type, and hydrogen may be recycled.ALSO:A reforming catalyst comprises platinum or palladium and a silica-alumina cracking component having a surface area of about 10-65 square meters per gram.  The platinum or palladium content is preferably 0.01-2.5 per cent by weight of the catalyst. The silica-alumina may be derived from natural materials or prepared synthetically, and its surface is reduced, before depositing the platinum or palladium, by steaming at 900-1400 DEG F and atmospheric to 100 lbs. per sq. in pressure or by heating at 1600-1800 DEG F. Regeneration may be effected by treatment with a gas containing 2 per cent oxygen at 900-950 DEG F and increasing the oxygen content up to that of air.  The catalyst may also contain low surface area silica-zirconia, silica - alumina - zirconia, silica - magnesia, silica - alumina - magnesia, silica - thoria, silica - alumina - thoria or alumina - boria, and a hydrogenation component e.g. oxides of chromium, molybdenum, tungsten, and uranium, metallic nickel, cobalt, and iron, and molybdates, thiomolybdates, phosphates, tungstates, chromates and borates of nickel, cobalt, and iron.  The catalysts are used for reforming petroleum distillates in the presence of added hydrogen to form products with high anti-knock values (see Group IV(b)).

Title: Improvements in and relating to Multi-colour Kinematograph Films.
Inventor: THORNTON JOHN EDWARD
IPC: G03B33/00
Filed: 1915-05-13
Abstract: 100,629. Thornton, J. E. May 13, 1915. Kinematograph apparatus. -- Multicolour kinematograph films for projection, in which each picture is a complete heliochrome. are produced from camera films of the multicolour-screen type by first preparing from the camera film a number of negative or positive clichÚs, in which the original screen pattern is obliterated, and using these clichÚs for making superimposed, prints on the final positive film; the prints may be made by any suitable photochemical or photomechanical process, the same or different processes being used for each. ClichÚs are made for each colour in the camera film by the use of selective colour filters during exposure, and the screen grain is obliterated by shifting the position of the printing- light during the exposure, a transparent film of corrugated or crimped celluloid being preferably interposed between the camera film and the clichÚ film. Alternatively, when the screen elements are parallel lines, a mask, having opaque lines separated by transparent spaces which are equal in width to one of the screen lines, may be used to separate the colours during exposure, the pattern being obliterated either by shifting the positions of the camera film and mask relatively to the clichÚ film and making exposures for each position until the whole of the clichÚ film is exposed, or by shifting the position of the printing-light during exposure. The edges of the opaque lines may be vignetted to minimize defects due to partial overlapping of the lines of the image. Two or more clichÚs may be made for each colour of the camera film, different exposures being given for each clichÚ, or differing colour filters being used; and by making prints from these clichÚs in the same or different shades of colour, a long scale of gradation and better colour effect may be obtained. The clichÚs may be printed from directly, to produce silver images, which are dyed or converted into dye images, or to produce " carbon " images, or bichromated gelatine images which are dyed. They may, alternatively, be used to produce other clichÚs, which are used for printing, or to produce photomechanical printing-belts, which may be prepared for example, by the methods described in Specification 5100/15, [Class 98 (ii), Photographic Processes &c.]. One image may be a cyanotype or other photochemical image, and the superimposed images may be printed photomechanically. Accurate register may be obtained by means of perforations in the clichÚs, printing- belts, if any, and the final film for projection, which are used in conjunction with the perforations in the camera film.
