Title: Improvements in processes and apparatus for photographic contact and reflex printing
IPC: G03B27/16
Filed: 1947-11-03
Abstract: 651,852. Photographic contact and reflex printing. KENT, D. E. Nov. 3, 1947, No. 29246. [Class 98 (ii)] [Also in Group XL (a)] A process for photographic contact or reflex printing on to a sensitized surface of a flexible sheet, plate, or the like, utilizes a lamp or other source to produce radiations of a wavelength to activate a fluorescent coating on a sheet, which sheet is of a material offering little impedance either to the radiations produced by the fluorescence or to the activating rays, the sheet being mounted in contact with or close proximity to the negative and sensitized surface, and the secondary radiations from the coating being principally or substantially entirely of a wavelength corresponding to the peak range of wavelengths effecting maximum photo-chemical change in the sensitized surface. The lamp may be a known kind of ultra-violet ray lamp providing activating radiation in the wavelength range 2000-4000 Angstrom units. The radiations produced by the fluorescence, in a blueprint process, have a wavelength range of about 3500-4500 Angstrom units. The flourescent material is preferably coated on the side of the sheet opposite the negative and sensitized material, in which case the sheet is made of material transparent to the rays produced by the fluorescence; alternatively the sheet is coated on the side next to the negative and sensitized material and is made of material transparent to the activating rays. The sheet may be made of quartz glass or Woods glass, and the fluorescent coating is made of a substance or mixture of substances such as zinc beryllium silicate, or silicates, orthosilicates and tungstates of metals such as zinc and cadmium. In apparatus for carrying out the process, Fig. 2, a glass cylinder 9 is supported on end-plates 8 which are rotatably mounted in bearings on spaced end supports 2. About half the inside of the cylinder has a fluorescent coating deposited thereon, or (according to the Provisional Specification) incorporated therein. A lamp in a holder 13, extending axially within the cylinder, emits ultra-violet radiation exciting the coating, and has a reflector 14. An apron 18 wound on a spring-loaded roller 17 is fastened at its free end to the cylinder at 19. The negative and sensitized material are inserted between the apron and the cylinder 9 as the latter is rotated. A plunger 20 in a mounting on the support 2 enters a recess in the end-plate 8 when the cylinder is fully rotated to a position in which the coated surface overlaps the sensitized sheet and lies in the field of radiation from the lamp and the reflector 14. The lamp is energized for the exposure period, the plunger 20 is withdrawn, and the spring on the roller 17 rewinds the apron 18, returning the cylinder to its original position. The end plates are louvred to allow air to be drawn through the cylinder by a fan therein.

Filed: 1974-07-02
Abstract: 1452199 Metal-chlorine storage battery ENERGY DEVELOPMENT ASSOCIATES 2 July 1974 [2 July 1973] 29279/74 Heading H1B A storage battery 11 essentially as disclosed in Specification 1339060 having metal electrodes, preferably of zinc, and graphite electrodes to which chlorine is supplied, the chlorine being dissolved in an aqueous electrolyte, preferably of zinc chloride, and flowing through a circuit 15, 23, 13 including a pump 21, adjustable valve 27, and a dissolver 25 for dissolving the chlorine, has an additional flow circuit 29, 33 including a non- return valve 35, the chlorine hydrate store 31 and an adjustable valve 37. The temperature of the store 31 is maintained at a lower temperature than that of the electrolyte which enters from line 29, the electrolyte temperature being such, e.g. 15- 50‹C, that it decomposes the hydrate to form chlorine and water, the increase of pressure in the store caused by the generation of the products shutting the valve 35. The electrolyte flow through the store 31 thus ceases and no more chlorine is generated. On discharge, the battery 11 consumes chlorine causing a reduction in pressure to the lines 13, 33 whereby electrolyte flows through the store 31 to generate chlorine and make up the deficiency. The valves 27, 37 are set to give pressure drops such that the system is selfregulating in relation to the chlorine demands of the battery and operates to maintain the electrolyte saturated with chlorine. A small venting orifice 19 is provided in line 15.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1927-11-08
Abstract: 305,618. Automatic Telephone Manufacturing Co., Ltd., and Passmore, W. O. Nov. 8, 1927. Automatic exchange systems.-In a small system of ony ten lines, a Strowger-type switch hunts vertically for the calling line and is then stepped horizontally by impulses into engagement with the wanted line. The switch has two sets of wipers, the banks of one set which engages the calling line being multipled horizontally so that during the numerical operation contact is maintained with the calling line, whilst the banks of the other set which engages the wanted line are multipled vertically. Busy tone, dialling tone, and cabling howler currents which operate the wanted party's receiver are generated by relay interrupting arrangements, Fig. 3, the calling and busy tones being periodically interrupted by a series of relays I<1> - - I<3>. Hunting. When a subscriber, Fig. 1, removes the receiver, start relay S energizes over the loop, and selectable potential over earthed armature 13 and the loop is placed upon a terminal in the bank of a special vertical wiper 21. Relay S energizes relay D which is slow-to-release owing to a short-circuit at armature 38 around its upper winding. Relay D energizes the vertical magnet VM which lifts the wipers and deenergizes relay D. Intermittent operation of relay D and magnet VM thus continues until the marked level is reached when relay FG operates, disconnects the vertical magnet, and connects up the rotary magnet RM which rotates the wipers one step, releasing FG. Relay CO operates over wiper 17, releasing relay S. Numerical operation. Relay A now operates over the calling loop and energizes BA, B, the last-named extending the start circuit over lead 77 to the next switch. At the same time dialling tone from lead 75 is connected up. Since the switch has already taken one rotary step, the first impulse is absorbed by two-step relay PA which is operated over contacts 23, 25, 58, and transfers the impulsing circuit to the rotary magnet at armature 37. During the rotary movement relay E connects relay FG to the test wiper 60 and if the wanted line is busy, FG locks up on the release of E and connects busy-tone lead 76 to the a-lead. If the wanted line is idle, switching relay H energizes over wiper 60 and connects up ringing lead 74 which supplies a ' howler ' tone to the called party's receiver. When the called party replies, relay F operates and relay D acts as a feed on the called side. Dialling-tone, busy-tone, and ringing-current arrangements, Fig. 3. When relay B operates it connects earth over lead 78 to relay BR, V which respectivety generate busy-tone, and dialling and calling current. Earth on lead 78 also energizes relay I<3> which locks up and energizes P, this in turn locking up and energizing I<1>. The three relays are then in turn short-circuited and the whole cycle is repeated, relays I<2> and I<3> at contacts 72, 73 effecting periodic interruptions in the ringing and busy-tone leads, respectively.
