Filed: 1935-11-22
Abstract: 463,142. Photographic processes. KRUPA, V. Nov. 22, 1935, No. 32350. [Class 98 (ii)] A process for hardening and lubricating photographic films which have been previously exposed and developed comprises subjecting the film to the successive actions of a plurality of media comprising vapours, gases or atomized liquids. The film is supported on a rack in a cylindrical chamber 11 to which end covers 31 are secured by tie-bolts 26 to make the chamber air-tight. The chamber is first exhausted to ensure complete dehydration of the film by means of an exhaust pump 41 driven by the electric motor 46. An oil reservoir 122 lubricates the pump and controls the exit conduit 123 for the air. The film is then treated with the chemical media which are supplied through pipes 49, 50, to atomizers or carburetters 53, 54 regulated by valves 51, 52 respectively, and through a common feed pipe 57 into a heating chamber 103. The conduit then divides at a T-joint and the chemicals are fed through distributing pipes 105 to the outlets 105a, 105b &c., The chamber 103 is heated by three electric units 109, 111, mounted on an asbestos pad, the heat being controlled by thermostats 114A, 114B. Lubricating mixture is admitted to the expansion chamber 104 through an inlet 118, valve 119 and carburetter 120. The exhaust chamber 11 contains a baffle plate 101 placed above the expansion chamber 104 and allowing the gas to circulate round its edges. The first vaporized gas or mixture which may be castor oil and ether or carbon tetrachloride, is supplied via the inlet 49 and softens the film base. The valve 55 is then shut and a fixing agent such as a vapour containing chrome alum or white alum admitted from pipe 50 whereby the gelatinous emulsion is rendered insoluble and hardened. Finally after the vacuum has been broken and another vacuum established, the lubricant gas or liquid is admitted from the supply pipe 118.

Title: Improvements in carrier wave telegraphy
Inventor: CHITTLEBURGH WILLIAM FRANCIS S
IPC: H04L5/06
Filed: 1957-10-24
Abstract: 815,708. Multiplex systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 24,1957, No. 33198/57. Class 40 (4). A multi-channel carrier system has a group of channels placed side by side in the central range of a transmitted frequency band and provided with a corresponding group of carrier frequencies in the central range, further upper and lower groups of channels being formed by modulating, with different group carrier frequencies, each of two smaller but equal groups of carrier frequencies from the central range which have at least one carrier frequency in common. Preferably the bandwidth of each channel is 120 cycles and 24 channels are provided between 360 and 3240 cycles. As shown in Fig. 2, channels 7 to 18 in the centre of the transmitted band are associated with twelve carrier frequencies out of which two sets of six consecutive carrier frequencies are selected, one set being modulated with a first group carrier frequency so that one sideband forms channels 1 to 6 and the other set being modulated with a second group carrier frequency, preferably half the first carrier frequency, so that one sideband forms channels 19 to 24. Since it is preferable for the sidebands forming channels 1 to 6 and 19 to 24 to be separated from their associated set of six carrier frequencies in the central band by at least one channel bandwidth, the sets of six are advantageously chosen from channels 8 to 17: In the preferred embodiment the carrier frequencies of channels 9 to 14 are used in common for both sets and satisfy the requirement that one group carrier frequency should be twice the other. Four other selections are given which also satisfy this requirement and the selection of channels 8 to 13 and 9 to 14 is shown in Fig. 4 where carrier oscillators 7A to 18A are connected in common to the line 25 over channel modulators 7 to 18 and filters 7B to 18B. The oscillators 8A to 13A also connect in reverse order with channel modulators 1 to 6 and filters 1B to 6B which are connected in common to a group modulator 29 and, over a filter 31, to the line 25. Similarly, oscillators 9A to 14A connect in reverse order with modulators 19 to 24 which are connected to the line 25 over group modulator 26 and filter 28. The carrier frequency supplied to group modulator 26 comes directly from an oscillator 27 which also supplies the carrier for group modulator 29 over a frequency halving circuit 30. Specification 602,229 is referred to.
