Title: Locking device for electrical switches
IPC: E05B37/02
Filed: 1919-10-10
Abstract: 155,407. Vincent, J. A. Oct. 10, 1919. Switches, locking a n d unlocking. - Switches are locked against unauthorized use by associating w i t h a rotatable switch arm a sliding bolt having projections enabling the switch to be locked in any position by means of a combination lock. The switch comprises one or more rotatable contact-carrying members b<1> operated externally, moving over fixed contacts d. The switch is connected to the locking-bolt by a pin b<2> moving in a slot e<1> contained in the insulating portion j of the bolt e. The lock consists of permutation rings f<1>, f<2>, f<3> mounted in housings y, y<1> each ring having a diaphragm f<4> with a central hole f<5> and a radial slot f<6>. Correct setting of the rings brings the slots f<6> in line with the projections e<2> of the bolt e, allowing the switch to be operated.

Title: Improvements in or relating to method for preparing copy
IPC: B41L19/00
Filed: 1951-10-24
Abstract: 722,023. Photographic processes. DICK CO., A. B. Oct. 24, 1951 [Nov. 1, 1950], No. 24843/51. Class 98 (2). [Also in Groups XV and XVI] A method of producing copy from an original in which the letter outlines contain a radiationabsorbing heat-generating material comprises arranging the original in contact with a transfer sheet having a coloured coating and arranging a copy sheet in contact with the coated side of the transfer sheet, and directing radiations on to the original to generate heat in the letter outlines and cause corresponding areas of the coating composition to be reduced to molten condition and transferred to the copy sheet. The sheets may be urged together by vacuum or pressure. The dark design areas of the original should contain activators or substances capable of converting light rays into heat. The radiation may be by radiations rich in infra-red, of wave-length 8000-40,000 Angstroms, and may be produced by a photographer's flash bulb, tungsten filament lamp, carbon arc lamp or infra-red ray lamp. The heat should be produced rapidly and the exposure be short, and for this purpose the source of radiation may be a capacitor device similar to that used in industrial spot-welding, or a hot wire or tubular tungsten filament lamp with the use of lenses or reflectors. The radiation source may traverse the original at a constant speed so that exposure of each part is of short duration. An assembly suitable for use in carrying out the invention comprises a housing 15 with a glass lid 17, and a flexible blanket 18 sealed all round its edge to the housing. The original 10, transfer sheet 12 and copy sheet 14 are placed on a plate 16, on the blanket, and pressure is produced in the housing or a vacuum generated in the space above the blanket so as to compress the assembly against the lid 17, through which the radiations are directed. The coating composition of the transfer sheet should be substantially solid and non-tacky at room temperature and become molten at some temperature between 125 and )5000 F. The coating may be formed of wax, paraffin, bitumen, or hydrocarbons or fatty acids or their derivatives, with or without oils or plasticizers. Dyes and pigments may be added to produce desired colours. Other low-melting point solids may be used, such as the natural gums and resins which include rosin, shellac, gum elemi, copal, dammar, sandarac, colophony, or amber, or thermoplastic synthetic resinous materials such as ethyl cellulose, nitrocellulose, polyacrylates, polyalkylacrylates, polyethylene, polystyrene, or polyvinyl acetates, with or without plasticizers. Examples of coating compositions are:-(1) (violet-coloured coating), methyl violet 5 parts, oleic acid 10, montan wax-crude 60, petrolatum 90; (2) (black), carnauba wax 9, montan wax 6, methyl violet 7, mineral oil 63, lampblack 15; (3) (blue), carnauba wax 4, paraffin wax 4, ozaokerite 1, octadecyl alcohol 2, cottonseed oil 2, Prussian blue 2.

Filed: 1928-08-29
Abstract: 322,471. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 29, 1928. Gases, treating with electric discharge.-In the treatment of gases or vapours with a plurality of arc discharges arranged in parallel, a pressure difference of at least 100 mm. of mercury exists between different parts of each discharge gap. This may be effected by supplying the gas through hollow electrodes as shown in Fig. 1, or through tubes surrounding the electrodes, or through tubes converging in the middle of the discharge gap as shown in Fig. 3. The Provisional Specification describes also the application of the invention to other kinds of electric discharge than the arc.

Abstract: 301,986. Alexander, J. A. R. Sept. 26, 1927. Developing apparatus. - Films, connected in a series end to end, are held during development on a concentric series of nesting reels upon each of which the film band is helically wound, the winding proceeding progressively from the innermost to the outermost reel. The end flanges of the innermost reel are supported on a shaft 12 adapted to rest in half-bearings 13, Fig. 4, at the top of any one of a series of treating-tanks 14 to which the films are to be transferred successively. The flanges of the remaining reels are in two semicircular parts hinged together at one end of a diameter, and detachably connected at the other end as by hooks mounted on the rods and joined by an elastic band, so that each reel can be opened out when assembling the nest. The flanges of successive reels grip one another frictionally, so that all the reels will rotate with the spindle 12 when a friction disc 15 thereon is driven by a shaft 17, Fig. 4, coupled to an electric motor 19, this rotation being necessary as the nest of reels is only partially submerged in each tank. Screw-means 21 is provided on the end of each tank to move the spindle 12 axially and adjust the frictional engagement of the disc 15 with the respective disc 16 on the shaft 17. For winding, the films are connected end to end as by staples, and, the reels of the nest having been taken apart, the end of the band is secured by a clip to a rod at one end of the innermost reel, and winding is commenced helically on this reel from end to end. The next reel of the nest is placed in position over the first, and the winding is continued on this reel helically in the opposite direction. This opera. tion is continued until the whole band of films has been wound, and the free end is clipped to a rod of the outermost reel.
