Filed: 1949-08-16
Abstract: 685,209. Control systems for lighting, WILLIAMS, R G. Aug. 16, 1950 [Aug. 16, 1949; Feb. 3, 1950], Nos. 21305/49 and 2875/50. Class 38 (iv). A colour control system, for obtaining lighting effects by combining in different proportions the light from differently coloured lamps W, R, G, B, comprises dimmers A, B, a three-bank rotary selector switch C and a rotary " colour-intensity " range switch D, the two dimmers and the selector switch being operated simultaneously, but at different rates, by a common control member. The arrangement is such that, with the range switch set in either the "deep colotir or " pastel positions, movement of the selector switch progressively through positions 1-9 successively connects a different one of lamps R, G, B to the supply 100, 101 over contacts 39, 56-60, whilst another lamp of different colour is connected to the supply through dimmer A over contacts 40, 42-49. As the switch C moves from one position to the next the lamp associated with contacts 42-49 is faded up or down and is then either transferred to one of' contacts 56- 60, in order to remain at full brilliance for a period, or is disconnected at contacts 42-49. In the " pastel position of switch D, the white lamp W supplements the others and is faded down by dimmer B whilst the switch C moves from position 1 to position and then faded up from position to position 9. In a modified arrangement the dimmers move at the same rate but are out-of-phase with one another. A switch mayalso be provided whereby either of two control ranges of the dimmer associated with the white lamp may be selected. The common control member may be motor-driven. Specification 646,642, [Group XI], is referred to.

Abstract: 1,018,971. Bookbinding. R. O. H. BULL. Nov. 15, 1963 [Aug. 16, 1962], No. 21359/62. Heading B6A. [Also in Division B5] Fibrous materials, e.g. pages of books, are joined by applying a light holding pressure to sheets 13 of the material in the region of their interengaging surfaces and subjecting the sheets 13 to sonic or ultrasonic vibrations in a direction at right-angles to the interengaging surfaces. A magnetostrictive transducer 10 mounted on a support 11 transmits highfrequency mechanical pulses of L wave to a tapered copper horn, probe or wave guide 12. The sheets 13, of paper or fabric of natural or man-made fibres, are supported on an anvil 14 of relatively great mass. The pressure between the anvil 14 and the probe 12 is adjustable by movement of a mass 17 on a pivoted lever 16 having a ram 15 pivoted thereto or by electrical or hydraulic means. On energizing an oscillator 20 and an amplifier 19, high-frequency impulses are transmitted to the transducer 10 while an additional coil winding (not shown) on the transducer 10 generates a pulsed feed-back to the oscillator 20. In modifications, the sheets 13 are held between the probe 12 and a freely rotatable metallic wheel, Fig. 3 (not shown), or are held between two freely rotatable metallic wheels 24, 25, Fig. 4, the probe 14 being in contact with the wheel 25. The vibrations may be at frequencies from 500 cycles to 500 kilo-cycles per second and the magnetostrictive transducer 10 may be replaced by a piezo-electric transducer or moving coils. The probe 12 may, alternatively, be made of stainless steel or cadmium. The holding pressure applied to the sheets during the application of vibrations is between 4 1b. and 200 1b. loading. Specified fibrous materials are nylon, polyethylene terephthalate, paper and wood pulp. The fibrous material may be combined with fillers, plastics or metal foils.

Title: Method of and apparatus for lasting footwear
IPC: A43D25/053
Filed: 1948-08-13
Abstract: 654,999. Cement lasting. KAMBORIAN, J. S. Aug. 13, 1948, No. 21401. [Class 17(i)] A method of cement lasting footwear comprises applying an updrafting and an in-wiping stress to the upper or platform cover while the shoe is held inverted against a hold-down and the application of adhesive near the point at which the holddown stress is applied. As shown, the updrafting stress is applied by two rollers 3, 4, Fig. 15 and the in-wiping stress by two wiper blade members 51, 52, while the cement is applied by the hold-down foot 10. A plough 50 may be reciprocated by a cam 67 on a shaft 31 to pull up the platform cover into the bite between the rollers 3, 4, when operating on a platform shoe. The wipers are reciprocated in guides 131, 132 by a cam shaft 120, (not shown), and have rigidly fixed to them rollers 135, 136 urged on to cam plates 133, 134, by springs 137, 138 so that when advanced they strike against the shoe margin with a hammering action and are raised on the return stroke. The hold-down foot 10, Fig. 17, has a bore 14 through which cement is forced from the tank 93 by a piston 90 operated as required by a treadle rod 104. An orifice 57 and roller 58 apply cement to the platform sole and cover strip respectively at a location remote from the peripheral edge of the sole. For use with thermoplastic cement. heaters 108, 109 are provided while the tube 94 has an insulating jacket J. At the point of application the adhesive may be cooled by a jet of air. In operation on a platform shoe the roller 4 is moved away from the roller 3 on a slide E and the cover W is introduced between them, the shoe being held against the hold-down foot 10 and a boss 55 on the roller 4 acting as an auxiliary hold-down. The machine is started and the treadle depressed to force adhesive out of the foot 10. The cover is updrafted by the rollers 3, 4, and in-wiped and pressed down by the wipers 51, 52 which, since they act out of phase, maintain the cover pressed down until the adhesive is sufficiently set. In a modified form the wipers are replaced by a rotating helix member extending transversely across the shoe bottom and in a further modification this member co-operates with a single roller, the end of which acts as a hold-down and through which cement is supplied. If a cement having volatile solvents is used the wiper and/or the inside of the lasting margin directly before in-wiping, may be heated by a jet of hot or burning gas to accelerate the setting of the cement. Specification 541,643, is referred to.

Abstract: 312,852. Hall, J. A., and George, W. F. C. July 26, 1928. Treating with air.-In a device for treating grain, as it falls down a tower, with currents of hot and cold air caused to flow transversely of the tower, hot air, which has not passed through the grain, is introduced into the exhaust conduits to prevent the deposition of moisture in such conduits and the subsequent accumulation of light material therein. In the tower a grain fed at the top b flows over inverted troughs d - - g. Hot air passes from a header h at one side of the upper portion of the tower into the trough e and after passing through the grain escapes through the alternative troughs d into an exhaust header i wherein it passes by a pipe j to a fan m and a beater n and so back to the beater h. At the bottom of the tower alternate troughs g are open to the atmosphere and the other troughs f communicate with a header and exhaust conduit o that leads to a fan p and a dust separator q. A passage j<1> permits air from the pipe j to be passed to the fan p. Each of the inverted troughs d leading to the exhaust header i is provided at its far end with one or more small apertures r opening into the hot air header h thus permitting hot air to pass directly to the exhaust conduits of the apparatus. The hot air may also be passed directly from the one header to the other by a damper-controlled byepass s. The tower is provided with a section k having no air connection and disposed between the upper hot air treatment section and the lower cooling section.
