Title: Improvements in and relating to imbibition processes for producing pictures in colour
IPC: G03C7/25
Filed: 1929-08-08
Abstract: 333,392. Uvachrom Akt.-Ges. fur Farbenphotographie. Feb. 16, 1929, [Convention date]. Printing designs on gelatine.-For the production of pictures in colour by the dye-impression process from a hardened gelatine relief, dyestuffs of a specific degree of dispersion, obtained e.g. by dialysis, are used to colour the relief, and the latter is treated with distilled water to remove absorbed particles of dyestuff of low dispersion. In special cases, with soft lights and deep shadows the relief may be treated beforehand, with solutions of alcohol-acids, e.g. glycollic acid which slightly swell the relief, and when the latter is prepared by the use of a bichromate sensitizer, a filter absorbing yellow rays is used during the exposure to reduce the graduation. The depth of diffusion of the dyestuff into the gelatine layer to be printed may be reduced, by the addition of a hydrated colloid, e.g. casein, to the layer.

Title: Improvements relating to textile carding machines
IPC: D01G31/00
Filed: 1952-10-01
Abstract: 730,215. Alarms in carding-engines. DAY, J. Sept. 24, 1953 [Oct. 1, 1952], No. 24556/52. Class 120(3). Feeding arrangements for textile carding machines comprise means which ensure that should the rate of charging of the weighpan fall below a predetermined minimum, due to the level in the hopper being unduly low or should the feeding mechanism fail so that the time taken between the commencement of charging of the weighpan and the dropping of the latter when charging is completed, is unduly prolonged, an indication will be given to the operative so that corrective action can be taken. The apparatus shown comprises an electrical device which depends for its operation on two switches which when operated in correct sequence keep the warning device out of service but which when operated in the wrong sequence provide visual and/or audible signals. In normal operation when the weighpan 1 is completely charged, the restraint of a counterweight 2 is overcome, the pan descends carrying a toothed wheel 5 into engagement with a rack 6 and also rotates and opens a switch 10 through a lever 12 : the rack 6 is caused to move from left to right to rotate and so empty the pan by a crank 7 which is driven intermittently and completes one revolution while a constant-speed shaft 9 turns through a small angle, say 45 degrees, and remains stationary during the remaining angular movement in each revolution of the shaft 9 : a two-part cam 16, the dwell of which may be adjusted, is rotated by the shaft 9 and actuates, in timed relation to the crank 7, a lever 15 to rotate and open a switch 13 which is thus closed after the pan 1 has dropped (and opened the switch 10 at the normal rate of filling) and opened before the rack 6 commences movement. When a misweigh is impending, both switches 10 and 13 are closed and, being connected in series, complete an alarm circuit to sound a hooter : additional switches may be fitted to the shafts 11 and 14 to control signal lamps. Warning devices relating to a number of machines may be interconnected e.g. circuits may be arranged so that a hooter indicates a fault in respect of any of the machines and a lamp identifies the particular machine, Fig. 2 (not shown).

Title: A process for making reproductions from an original
IPC: B41M5/26
Filed: 1966-06-02
Abstract: 1,121,218. Making reproductions. FUJI SHASHIN FILM K.K. 2 June, 1966 [5 June, 1965], No. 24702/66. Heading B6C. Reproductions are made by forming an oil latent image of an original on a support, developing this image with a powdery material which only becomes adhesive when heated to 70 to 170 C. and remains adhesive when subsequently allowed to cool, transferring the developed image by heating to an imagereceiving sheet, and powder developing and fixing this latter sheet. The oil latent image may be prepared by relief printing using an oily ink; typewriting using an oil-impregnated ribbon; applying a low-boiling oil to an original and exposing to infra-red heating so that the oil corresponding to the characters of the original evaporates on to a support placed on the original; inserting an oil-impregnated, paper between the original and the support and exposing to infra-red radiation; or utilizing heat-or pressure-sensitive capsules containing an oil. Examples on a sheet which is typed or written on of the thermo-adhesive powder developer include benzoic acid, sebacic acid, phthalic anhydride, cinnamic acid, maleic anhydride, benzotriazole, p-dimethylammobenzaldehyde, benzoin, dextrose acetanilide, vanillin, methylhydroquinone, 2,4-dehydroxybenzophenone and #-napthol which are preferably ground to 0À1 to 100 microns in diameter and may have infra-red ray absorbers and other high melting-point powders incorporated. The powder developer for the image-receiving sheet should preferably be capable of attaching the thermo-adhesive material transferred from the support in the adhesive state; the powder is thus attached only to the image portions if the transferred image is developed immediately after transfer. This powder may also be coated with surface active agents, e.g. succinic acid, alkyl ester sulphonates, alkylbenzene sulphonates, sorbitan alkyl easters, long-chain quaternary ammonium salts or polyoxyalkylene sorbitan alkyl esters. A number of reproductions can be produced from each intermediate sheet or support.

Title: Microwave device
IPC: H01P1/11
Filed: 1959-07-17
Abstract: 868,186. Waveguide switches. HUGHES AIRCRAFT CO. July 17, 1959 [Aug. 12, 1958], No. 24708/59. Class 40(8) A microwave switch or phase-changer comprises a waveguide in which is arranged an elongated member of wave-permeable gyromagnetically-resonant material having a longitudinal slot through which pass the tunes of a magnetizing winding. In the switch of Fig. 2 an elongated slab 20 of ferrite having a longitudinal aperture 25 is arranged against or near to the narrow wall of a waveguide 12. A winding 30, situated entirely within the waveguide, provides a magnetic field within the ferrite which is predominantly normal to the broad walls. It is stated that, in the magnetized condition, the ferrite element causes generation of higher-order modes in the waveguide and that coupling between these modes causes reflection of energy. The device does not utilize absorption due to gyromagnetic resonance. Mode coupling may be improved by the use of tuning screws 50 which are stated not to affect propagation in the unmagnetized (closed) state of the switch. Dielectric loading may be used for the same purpose. The device may be used without the tuning screws as a phase-shifter. In another form of phase-shifter (Fig. 5) an elongated ferrite member 29 having a longtitudinal aperture 27 is arranged on the centre line of a broad side of waveguide 12. A winding 30 provides a predominantly axial magnetic field within the element. The phase-shifter may be associated with other devices, e.g. hybrid-T-junctions, to form a switch.

Abstract: 484,174. Making hollow glass blocks. OWENS - ILLINOIS GLASS CO. Sept. 13, 1937, No. 24901. Convention date, Oct. 31, 1936. [Class 56] A method of making a hollow glass block containing air at a low pressure consists in moulding a block in two sections, welding the two sections together along their edges, and then continuously drawing a ribbon from a mass of molten glass and applying it to the heated junction between the sections. Apparatus for making the blocks comprises a sealing machine arranged between two forming machines each of which makes sections of the finished blocks, conveyers for carrying the sections to the sealing machine, and another conveyer for carrying the finished blocks to a leer. The sealing machine comprises a pair of parallel vertical plates 28, Fig. 2, which are rotated step-by-step about a hollow horizontal shaft 27 and are provided with chucks 35 for gripping the glass blocks 12. The chucks comprise hollow plungers 34 which slide through the plates 28 and are moved longitudinally by springs 38 and by cam tracks which engage rollers 39 on the ends of the plungers. Suction. is applied through the plungers to cause the chuck heads 35 to grip the glass blocks. In operation, pairs of block sections, brought to the machine by the conveyers, are received in cradle-like supports 14, Fig. 3, which are raised by pneumatic cylinders 16 to carry a pair of block sections into position between a pair of chucks. Each section of a block has a continuous groove 17, Fig. 2, along its edges, as described in Specification 484,173, and when the sections are pressed together by the chucks, the grooves form a continuous channel 19 to which the sealing ribbon of glass is applied. Immediately the block sections are pressed together, they are carried by the movement of the plates 28 to two reheating stations I, II, Fig. 3, where the joined edges are reheated by the flames from blowpipes 62, 63. During reheating, the blocks are rotated through one turn by rotating segments 65, 66 which frictionally engage discs 64 on the chuck plungers 34. After reheating, a block is carried to the sealing station III where the channel 19 receives a ribbon of glass 78 which is drawn from a furnace forehearth 77. The block is turned through 180‹ by a rotating segment 83, and the ribbon of glass is applied to the channel 19 and is pressed into contact with the hot glass by an ironing roller 79. The block then moves to station IV and the application of the glass is continued during the movement. While at station IV, the ribbon of glass is severed between successive blocks by a shearing device 87 which also carries plates 88 that smooth the loose ends of the glass ribbon. Finally, the completed block is deposited on a conveyer that carries it to the leer.
