Abstract: 956,846. Hydraulic couplings. SCHWITZER CORPORATION. April 17, 1963 [April 19, 1962], No. 14978/63. Heading F2C. In an hydraulic coupling for driving a radiator cooling fan of the kind wherein a disc 26 fast with a driving shaft 12 is coupled by a fluid film to an output housing 11, 18 which includes a partition 19 that separates a reservoir 23 from a working chamber 24 and has an inlet port 35 controlled by a valve strip 34 and an outlet port 46, the partition 19 is extended at 19a externally of the housing to facilitate cooling of the coupling. As shown, the partition plate extension forms the hub of the fan. The valve strip 34, which is secured to the partition 19, is biased by its own resiliency to an open position and is closed by a pin 67 controlled by a bi-metal strip 63 responsive to the temperature of the engine coolant or the air flowing through the radiator. The partition outlet port 46 comprises a circular aperture which may be closed by a spring-pressed plug 46a and an adjacent continuously open semicircular aperture (Fig. 1, not shown). On starting, with the engine cold, the inlet port 35 is closed and the working chamber 24 is exhausted through the port 46. As the engine heats up the bi-metal strip 63 permits the valve strip to open the port 35 and the housing is driven. Facing members 28, 51 formed with radial grooves and holes in the disc 26 permit toroidal circulation of fluid in the working chamber. Specification 841,703 is referred to.

Filed: 1933-05-27
Abstract: 419,887. Colour photography. THORNTON,. J. E., 8, Hill Street, Jersey, Channel Islands. May 27, 1933, No. 15348. [Class 98 (ii).] Three component colours are recorded at one exposure on a film or plate bipack comprising a plain red-sensitive front element and a blue-green sensitive rear element carrying a mosaic blue and green two-colour screen. To restrict the selective actions of the two sensitive layers, plain filters may be included, or the emulsions may be stained by filter dyestuffs. The emulsion speeds are chosen to give records of equal density. Registration marks are provided by notching both elements, or by providing opaque dots in the margin of the front element, which print through on to the rear element. The elements may be on a common support, and developed together ; or they may be on separate supports placed together with supports outermost (contact being ensured as by evacuation or temporary adhesive), and separated for development. Positives are produced by printing the continuous-tone negative on one film, and the mosaic negative by filter selection (and with dot-diffusion if desired) either on opposite sides of doubly-coated stock with the aid of a light-splitting device, or on separate sensitive elements, the prints being subsequently cemented together. The prints may be made on ready-coloured stock, sensitized with silver or bichromate and developed as reliefs ; or on uncoloured stock, and chemically or dye toned after developing as by applying coloured colloid solutions, or by the " carbro " method, which may be modified as described in Specification 417,640. The colours of the prints are blue from the red-record negative, and magenta and yellow or red and green from the mosaic negative. In manufacturing the bipack, the two-colour screen may be applied to the rear element by transfer from a temporary support. The invention may be applied to kinematograph films. Specifications 112,769, 238,688, 283,765, 321,998, 328,336, [all in Class 98 (ii)], 371,009, and 414,056 also are referred to.

Title: Improvements in or relating to machines for attaching heels or parts thereof to boots or shoes
IPC: A43D79/00
Filed: 1928-05-26
Abstract: 318,094. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). May 26, 1928. Heels, machines for. - In a machine for attaching whole heels, heel bases, top lifts, or like heel parts to shoes, the fastener holders are independently movable, and, prior to the driving of the fasteners, are automatically urged to operative position so that the fasteners are driven at a. predetermined distance from the edge of the heel. The fastener holders are pivoted and provided with gauges which engage with the work. A jack for heel attaching from inside the shoe comprises a heel plate 5, Fig. 1, on a post 1 formed with vertical grooves housing fastener holders 11 each of which is pivoted at 13 on a pin engaging fixed radial horizontal slots 10. The holder bore is curved so that the driven fasteners converge towards the tread of the heel, the drivers 21 being flexible and secured to their operating plunger 25 by ball joints. Blocks 17 retained by a spring ring 19 maintain the assembly in position. As the pivots 13 are affset from the drivers, friction of the drivers in their passages causes the holders to move outwardly, prior to the driving of the fasteners, until gauges 31 engage the counter of the shoe. For heel part attaching from the outside of the shoe, fastener holders 33, Fig. 2, pivoted at 35 each house a driver bar operated by a link 41 pivoted at 43 to a plunger 39, the pivots 43, 45 of the link being offset so that the thrust has an inward component causing gauges 53 to contact with the work prior to the driving of the fasteners. Spring plungers 51 provide friction on the driver bars. In this form, an additional non-adjustable driver bar 63 drives a fastener adjacent to the heel breast.
Patent GB-1117968-A (GB)
Title: Improvements in or relating to the disproportionation of alkenes
Inventor: ALKEMA HENK JOHAN
IPC: C07B61/00
Filed: 1967-04-05
Abstract: Acyclic olefins are disproportionated in the presence of a suitable catalyst and molecular hydrogen.  The presence of hydrogen retards catalyst deterioration, promotes catalyst activity, and enables the process to be conducted without the need for removal of conjugated alkadiene contaminants from the feed.  By suitable adjustment of the amount of hydrogen and the type of catalyst, the olefin products can be simultaneously hydrogenated, either partially or completely. Since hydrogenation of lower olefins under these conditions proceeds more easily than that of higher olefins, the process may be used to convert an alkene feed into a mixture of lower alkanes and higher alkenes. Suitable catalysts contain one or more oxides, sulphides, p -alkenyl or carbonyl derivatives of molybdenum, tungsten or rhenium, supported on alumina or an admixture thereof with up to 25% of magnesia, thoria or silica.  A mixture of molybdenum trioxide and cobalt oxide on alumina is particularly suitable. The selectivity of the catalyst may be increased by the presence of an oxide of potassium, rubidium or cesium, and the hydrogenating activity thereof by the presence of metallic Fe, Co, Mn, Ni, Pd, Pt, Rh or Ru, or an oxide, sulphide, p -alkenyl or carbonyl derivative thereof.  Numerous gaseous or liquid diluents are mentioned, and the process may be effected in the gaseous or liquid phase using any desired form of catalyst, e.g. fixed bed, fluidized bed or slurried.  Examples describe the conversion of propylene to ethylene and butene, or to ethylene, ethane and butene, and of butene-1 to a variety of product mixtures comprising mainly alkenes, mainly alkanes and various intermediate mixtures.

IPC: B23K11/24
Filed: 1951-07-04
Abstract: 680,198. Converting. BRITISH THOMSONHOUSTON CO., Ltd., and HIGGINS, B. G. July 4, 1951, No. 15874/51. Addition to 674,327. Class 38 (ii). In an electric welding system in which reversely connected pairs of ignitrons are controlled through a commutator chain with two sets 21, 22 of conducting and insulating segments as described in the parent Specifications, brushes 72, 73 are arranged to engage the non- conducting segments 70, 71 in the gap between sets of conducting segments 27, 28 just before the last main valve of one group is fired by contact of brush 24<SP>1</SP> with the last of conducting segments 28. Part of variable resistance 62 in a phase-adjusting circuit then ceases to be short circuited through blocking condensers 74, 741 and the brushes 72, 73 and conducting segments on the commutator chains, and the firing angle of this last main valve is retarded to reduce the value of the last half-cycle of a firing pulse. This forms an alternative circuit to that described in the parent Specification, whereby the danger of back-firing of the first main valve of the incoming group is reduced. Where the groups of conducting buttons are suitably arranged, the start or stop brushes 23, 231 and 25, 25<SP>1</SP> may be used instead of the special brushes 72, 73.
