Title: Improvements relating to prepayment devices
IPC: G07F15/08
Filed: 1929-06-22
Abstract: 333,998. Cheetham, G. A., Lister, H., and Associated Chemical Industries, Ltd. June 22, 1929. Price-changing mechanism. - In prepayment meter mechanism in which travel of a coin-freed shaft is transmitted to a commodity shaft alternately through a pair of gears having different velocity ratios, the manually operable coin shaft .drives an operating wheel 1 for the differential quantity mechanism through an idler engaging a wheel 4 on a shaft 3 and two gear mechanisms which constitute the price-changing gear and are accommodate as a single unit on shaft 2, 3. At first, the pinion 4 drives the wheel 1 through a wheel 5 loose on the shaft 2, but having a pawl 6 driving a ratchet wheel 7 fixed on the shaft which also has a pinion 8 meshing with the wheel 1. After a predetermined number of coins have been inserted, a threaded wheel 9 has been moved along a screwed portion of the shaft 3 so that a projecting pin 12 thereon engages an arm 18 on the shaft 16 of a pawl 17 to engage this pawl with a ratchet wheel 19. The pawl is mounted on a disc 15 fixed to the shaft and now drives the ratchet wheel 19 and an associated wheel 21 which are loosely mounted on the shaft 3. The wheel 21 meshes with a wheel 22 attached to the ratchet wheel 7 so that the wheel 1 is now driven at a greater speed, the ratchet wheel 7 overrunning the pawl 6. The wheel 9 is normally prevented from rotating by engaging a pinion 24 the shaft 25 of which is frictionally held in a fork 26 of a lever 27 held by a lever 30. The lever 30 is retained in holding-position by the cash-box 31 of the meter. When the cash box is pulled out, the wheel 24 is freed and allows rotation of the threaded wheel 9 under the action of a spring 23 connecting it to the disc 15. The wheel 9 is thereby moved back to its initial position with a projecting pin 13 engaging a stop pin 14 fixed by a collar 15 to the shaft 3.

Patent GB-680781-A (GB)
Title: Improvements in or relating to variable inductors for high frequency tuning applications
IPC: H03J1/14
Filed: 1950-08-02
Abstract: 680,781. Valve amplifying units; adjusting radio apparatus. ALADDIN INDUSTRIES, Inc. Aug. 2, 1950 [Aug. 13, 1949], No. 19303/50. Classes 40 (v) and 40 (vi). [Also in Group XXXV] A tuned radio-frequency amplifier uses highfrequency variable inductors in the resonant circuits between control grid and cathode and between anode and cathode of the amplifying valve. The inductors form part of a tuning apparatus operable from a single control. The inductors 42 comprise helical coils which each have separated groups of widely spaced turns with an intermediate group of closely spaced turns, the tuning being effected by movement of conducting sleeves 44. The sleeves 44 are each attached to a carrier 20 arranged to be moved laterally by means of a control on the shaft 12, rotational movement of which causes the cam 22 to rotate so that, since the rollers 28, 26 are constrained to follow the contour of the cam, the carrier 20 moves in a lateral direction, rotational movement being prevented by a protuberance 20b moving in an elongated slot in a top plate 10c. The cam 22 has rigidly fixed thereto a star-wheel 22c, a roller 40 cooperating therewith to cause the shaft 12 to locate in the various channel positions. Both the rollers 28, 40 are carried on spring-loaded arms. The arrangement allows gradual increase in tuned frequency over the widely spaced turns of the inductors 42 which represent the television channels whilst the intermediate channels represented by the closely spaced turns are passed over relatively rapidly. Manufacturing tolerances can be compensated for by movement of the conducting sleeves and iron cores of the inductors relative to the carrier 20 and the end plate 10b respectively and also by movement of the shaft 14 in the collar 34. Specification 662,691, [Group XXXV], is referred to.

Patent GB-1095822-A (GB)
Title: Manufacture of thin film patterns
IPC: C08F2/48
Filed: 1965-05-10
Abstract: <PICT:1095822/C6-C7/1> A continuous thin film of material is vapour deposited on selected areas of a substrate having an organic surface, the selected areas on which deposition takes place being first irradiated in such a way that the sticking coefficient of these areas is greater than that of the remainder of the surface.  The film materials deposited may be metals such as Sn, Pb, In, Ag or chemical compounds including semi-conductors such as PbS and CdS.  The organic surface of the substrate may be formed by vapour depositing organic material such as silicone oil, bisphenal A-epichlorohydrin, resorcinol diglycidyl ether, methyl phenyl silaxane, or by adsorption of butyl methacrylate, vinyl acetate or methyl methacrylate to a thickness of 500 <\>rA.  The irradiation may be effected by electron beam or photolytically and the organic material is thus polymerized. The untreated i.e. unpolymerized portions of the organic surface may be polymerized by irradiation after deposition on the film material and a further outer layer of organic material may be vapour deposited on the film material. The process may be carried out in the apparatus shown in Figure 4.  A substrate holder 29 pivoted on 31 in position A is located above evaporation sources 37, 39 and 41, is controlled by temperature regulators 42, and also exposed to electron beam from gun 43.  The electron gun is programmed to supply the electron beam on substrate 9 in the required pattern after evaporation of the organic material from evaporator 41.  Alternatively when holder 29 is rotated to position B the optical system 51 is used to effect photolytic polymerization in the required pattern; butyl methacrylate, vinyl acetate or methyl methacrylate in gaseous form being introduced at 59. The substrate may be cooled by coils 161.  In the photolytic process it is preferred to illuminate the whole substrate surface with ultraviolet light to polymerize the surface and then to irradiate the selected areas with a light pattern of higher energy to produce the higher sticking coefficient. In an alternative method a negative pattern can be formed by using the irradiation to reduce the sticking coefficient of selected portions.  Thus with a polymeric film of high sticking coefficient with a cover layer with only selected portions treated by the optical system 51, the pressure in the vacuum chamber may be reduced to desorb the unreacted portions of said cover layer to reexpose the previously deposited polymeric film.
