Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/42
Filed: 1925-01-06
Abstract: 250,510. Automatic Telephone Manufacturing Co., Ltd., and Tench, F. Jan. 6, 1925. Drawings to Specification. Automatic exchange systems.-One or more of the registers of a register-controller are used to record successively two digits, control in accordance with the first being effected while the register is stationary in its first set position, and control in accordance with the sound being effected during the continuation of its movement to a particular position subsequent to its second setting. The first settings of a number of registers are transferred to a code switch for the transmission of a routing member under the control of a counting switch, but untranslated digits corresponding to their second settings are transmitted directly by the registers. For the transmission of these last digits, the register magnets themselves control contacts in the impulse circuit. The invention is described with reference to a register-controller of the code-translating type which is identical with that described in Specification 249,248, which claims other features. Specification 194,580 is also referred to, and Specification 194,427 and 220,774 are referred to in the Provisional Specification.

Filed: 1933-01-17
Abstract: 413,695. Printing by electrodeposition. DIGBY, E. T., 6, Queen Anne's Gate, London. Jan. 17, 1933, Nos. 1524 and 16529. [Class 41.] Imperishable records comprising printed characters, maps, diagrams, illustrations and portraits are obtained by electro-deposition of platinum or a metal of the platinum group on a suitably prepared sheet of incorrodible metal of the thickness of paper, i.e. not exceeding one sixty-fourth of an inch. The deposit should be applied as thinly as requirements permit and should not depend for its visibility on a bas-relief, relief, plastic, recessed or deepedged effect. In one method a design is applied by photo-transfer, lithography or otherwise to a sheet of gold alloy or nickel, and copper or other metal is deposited on the exposed parts. The initially applied design material is then removed and platinum is deposited over the whole to a depth of 0-00004 inch. The sheet is then treated in acid to dissolve the copper or other metal masking, the platinum above it being removed in a broken condition, leaving the design in platinum on a gold or nickel background. In a modification, the copper or other metal is deposited with a matt surface and is not removed, the final product exhibiting the design in bright platinum on a matt platinum background. In a third method a sheet of gold alloy or nickel is coated over its whole surface with copper before application of the design by photo-transfer or lithography. The unmasked portion of the copper is etched down to the gold or nickel level, after which the design material is removed and platinum deposited ; the copper and its overlying platinum are then removed as in the first method. The original sheets may be sandblasted or otherwise treated to obtain a matt effect throughout, or a smooth masking layer of copper or other metal may be deposited on the matt sheet so as to exhibit the design finally in matt platinum on a bright platinum background.

Abstract: 606,823. Softening water; filters. THOMPSON-KENNICOTT. Ltd., J., PAGE. G. C., and DAVISON, G. T. Jan. 16,1946, No. 1537. [Class 46] In a method of softening water part of the water is initially treated with an excess of lime or lime and soda to ensure complete precipitation of the magnesium, the remainder of the water is treated by a base exchange water softener and the softened water from both processes is intermingled, and the mixture is stored until a further precipitate is formed. The softened water may then be filtered. The water treated with lime or lime and soda is preferably mixed with sludge from a previous softening reaction and delivered to a settlement tank before being mixed with the water softened by the base-exchange method. The ratio of the amount of base-exchangetreated water to the amount of lime treated water is preferably substantially equal to the ratio of the permanent hardness to the temporary hardness of the raw water. In the arrangement shown, the inlet 1 for raw water is connected to a valve 3 which can be adjusted to divide the flow into two streams in any predetermined proportions. One stream flows to a dividing valve 5 which feeds some water to a dosing tank 9 supplied with lime water from a tank .6, and some water through a pipe 11 to a settling tank 12. The water from the dosing tank 9 also flows through pipe 13 to the tank 12. Raw water from inlet 1 also flows to a base-exchange water softener 20. The water from softener 20 mixes with the effluent from the tank 12 and passes into a settling tank 26, from which clarified and softened water is withdrawn after passing through a filter 28 of graded limestone.

Abstract: 571,141. Indicating faults; fuse bases. DELAPRE COMPONENTS, Ltd., STEVENS, R. J., MAJOR, P. C., and BARRON, B. S. Jan. 31, 1944, No. 1752. [Classes 37 and 38 (i)] [Also in Group XYXVII] Apparatus for testing fuses of the cartridge or of the slide-locking type comprises a box containing contacts with which either type of fuse may be engaged, an indicating lamp, and an isolating switch which is closed only when the door of the box is closed. The box 10, Fig. 4, is divided by a removable partition 15, into two compartments. In the left-hand compartment is an inclined V-trough 16 having upper and lower side contact plates 18, 19, with which the end contacts of a cartridge fuse may be engaged, and a lower contact 30 and a sliding spring-mounted upper contact 29b between which the contacts of a fuse of the slide-locking type may be gripped. The testing contacts are connected in series with an indicating lamp 17, in the right-hand compartment of the box, and with an isolating switch 39 of the telephone jack type. This switch is closed by a jack plug 51 when the hinged door 11 of the box is closed, thereby closing the testing circuit and causing the lamp to light if the fuse is intact. A window 52 in the door 11 enables the lamp 17 to be observed.. A push-button switch 53 enables the lamp 17 to be connected directly across the mains for checking the soundness of the bulb. On the inner face of the door 11 is a wedge 57 which can slide on a rod 58 against a spring 59. When the door is closed this wedge presses the fuse against the testing contacts. A socket 60 is provided for cartridge fuses of very small sizes, the circuit being closed by a spring contact 63 carried by the door 11. In a modification the switches 39, 53 are replaced by a single switch, Fig. 10, comprising a rotatable member 73 carrying a pair of contacts 77, 78 which co-operate with brushes 79, 80, 81. When the door is open the switch is in the position shown, in which the contacts 77, 78 are clear of the brushes. The member 73 may be rotated clockwise by a finger-piece 82 so that the contact 77 bridges the brushes 79 and the contact 78 bridges the brushes 80, thereby completing the lamp-testing circuit. Counterclockwise rotation is prevented by a pawl 87 which is moved into a detent 90 by a plunger 84 pressed rearwardly by a tailpiece 83 on the open door 11. When the door is closed the pawl 87 is moved out of the detent and the member 73 is moved counterclockwise by a wedge on the inner face of the door engaging beneath the finger-piece 82. The contact 77 then bridges the brushes 80 and the contact 78 bridges the brushes 81. closing the fuse-testing circuit.
