Patent GB-242457-A (GB)
Title: Improvements relating to switches and circuit arrangements for telephone systems
IPC: H04Q3/00
Filed: 1924-11-27
Abstract: 242,457. Siemens Bros. & Co., Ltd., and Patterson, W. G. Nov. 27, 1924. Addition to 219,740. Automatic exchange systems.- In systems in which, as described in the parent Specification, a line relay common to a group of subscribers is associated with a calling line by a finder switch, the latter is of no-normal type, and the common apparatus is released as soon as the line switch has moved from normal. Three arrangements are described, each of which involves the latching of certain contacts of the test relay while the line-switch is off normal. First arrangement, Fig. 1. When a subscriber calls, starting relay P pulls up over W, X<0> and the loop to ground at t<2>, and the driving magnet DMA steps the finder until wiper A<1> finds the calling terminal, which is marked over a branch of the starting circuit, resistances W being provided in the starting branches to ensure that relay TA only pulls up on calling terminals. Relay TA starts the line switch over wiper B<1> and at the first step wiper X<0> releases the common apparatus and wiper D<0> gives control of the stepping magnet to the test relay T, which cuts off its high-resistance winding I when an idle line is found. At the end of the call, contacts t<1>, t<4> fall back and the line switch is driven to normal. Contact t<5> however is latched, to nullify the normal testing function of relay T, until the switch is restored. On incoming calls, relay T is energized over all its windings, and marks the line busy. The contact t<5> is not latched since the switch is in its normal position. Second arrangement, Fig. 2. Except for the fact that the function of wiper X<0> is assumed by wiper D<0>, the operation of this arrangement is the same as that of the previous arrangement. It has, however, owing to the modification in the starting circuit, the peculiarity that a ground fault on a subscriber's b-wire will cause the common apparatus to be held until the line switch finds an idle line. Third arrangement, Fig. 3. This system operates in the same way as that shown in Fig. 1, but the make spring of the latched contact t<5> is omitted, its functions being assumed by a front contact t<4> and the off-normal arc of wiper X<0>. Selectors.-When the selector, Fig. 4, is in one of its normal positions, the latch 10 is held in the position shown by a projection 5 - - 7 on a plate 8 carried by the wiper shaft. In other positions the latch rests against the end of the spring 12, and when the relay T is energized the spring 15 causes the latch to come down to the right of the spring 12 and hold it in its operated position. The edge of plate 8 may be numbered to indicate the position of the wipers.

Title: Printing plate
IPC: G03F7/04
Filed: 1957-09-10
Abstract: 826,077. Planographic printing plate production. ENSINK. A. L. Sept. 10, 1957, No. 28550/57. Class 98(2) [Also in Group XVI] A planographic plate comprises a base sheet and a coating on the base sheet consisting essentially of an alginate which has been insolubilized to provide a hydrophilic water-receptive surface upon which an ink-receptive, water-repellant image may be formed, and including a finely divided filler in combination with the alginate in the coating. The base sheet, which may be of metal, cardboard or high wet strength paper, is first given a waterproofing coating, e.g. of casein, urea formaldehyde or melamine. The surface coating consists of a solution of sodium alginate or ammonium alginate. preferably a solution of 2¢-3%, and including one or more. fillers, e.g. barium sulphate or china clays, in the ratio of five to eight parts of fillers to one part of alginate. The alginate may be rendered water-insoluble by incorporating metal salts directly into the coating solution, e.g. aluminium chloride and zinc chloride, or calcium and iron salts, or by application of the metal salt as a separate wash-coat. The plate so prepared may be directly imaged by means of a typewriter or otherwise. The coating may be applied to the plate together with ammonium bichromate so as to provide a light sensitive coating. A suitable coating consists of 4 ounces of 2% solution of alginates, 6 ounces of water, and 4 ounces of a 10% solution of ammonium bichromate. When the coating is dry the plate may be exposed and developed in the known manner. The coating may further be applied with salts such as silver bromide, chloride or iodide to provide a photo-sensitive coating, which after drying may be exposed, developed and fixed for further use. The silver salt produced after developing and fixing is converted into a chromate salt by a bleaching agent, e.g. a solution of copper sulphate, potassium bromide, and chromic acid or ammonium bichromate, to render the developed image grease receptive. The alginates may be insolubilized upon drying by applying an alginate in solution as a water-soluble double salt or complex in which one of the cations comprises ammonium while the other is capable of forming a complex therewith such as zinc, copper, iron, cadmium and aluminium, thus obviating the use of metal salts.

Title: Apparatus for applying low pressure advance and high pressure squeeze in the hydraulic operation of die casting dies
IPC: F15B3/00
Filed: 1951-12-11
Abstract: 698,593. Casting-machines. PLASCO, Ltd. Dec. 11, 1951 [July 16, 1951], No. 29035/51. Class 83 (i). An apparatus for controlling a hydraulic medium used for operating the dies of a die-casting machine comprises a cylinder for hydraulic fluid and two pistons therein, one forcing fluid out of the cylinder to bring the dies together and a supplemental piston which then acts on the fluid to cause a high pressure squeeze on the die when in closed position, both pistons being actuated by pneumatically operated means. Within a casing 10 is a hydraulic cylinder 11 communicating with the die-operating mechanism by a pipe 60. The liquid within the cylinder may be acted upon firstly by a piston 19 moved down against a spring 24 by a cam 25 and secondly by a supplemental piston 57 moved up by a pneumatic piston 55 operating in a comparatively large diameter cylinder 15. The casing 10 also includes a pneumatic cylinder 12 containing a piston 29, an upper extension of which is formed as a rack to rotate the cam 25 through a gear 28. In operation, pressure air is admitted to the base of the cylinder 12 to raise the piston 29 and so rotate the cam 25 which depresses a follower-roll 22 in the forked upper end of the piston 19. Fluid is thus forced along the pipe 60 to effect the closing of the dies. As piston 29 reaches the top of its stroke it uncovers a port (not shown) and allows air to enter the base of the cylinder 15 thus forcing the plunger 57 into the cylinder 11 to produce the final squeezing of the dies. On connecting the cylinder 12 to exhaust, pison 29 is returned by a spring 48 and pistons 19, 57 by the spring 24.

Abstract: 505,478. Clockwork -actuated valves. ASSOCIATED APPLIANCES, Ltd. (Lerch, R.) Oct. 7, 1938, No. 29181. [Class 135] A valve which is automatically returned to an initial position after a preselected period has an operating member 16 movable against the action of a spring 20 through a distance corresponding to the operative range of the valve and through a further distance dependent on the preselected period in which it is operatively coupled to an escapement mechanism 15, the operating member 16 being released from the escapement mechanism for operation of the valve by the spring 20 when it has traversed back over the latter distance under the control of the escapement mechanism. As shown a gas cook 10 has a spindle 11 passing through a frame 12, 13 carrying the escapement train 15, and rotatably supporting a boss 17 on which the operating member 16 is mounted. The latter has a scale 18 visible through an opening in the cylindrical part 13. The spring 20 is secured at one end to the member 16 and at the other to a fixed post. The operating member 16 is formed internally with an interrupted gear 24 the plain portion of which corresponds to the operative range of the cock. The gear 24 meshes with the first pinion 25 of the escapement train 15, a spring 28 being provided to steady the pinion 25 when not in mesh with the gear 24. The operating member 16 has an abutment 35 movable in a groove 33 in a handle 29 non-rotatably but slidably mounted on the spindle 11. A neck 34 bridging the groove 33 is-engaged by the abutment 35 when the escapement is released from the operating member 16. 34a indicates the position to which the neck is set by the handle 29 for full opening of the cock. The cock may be manually-operated at any time simply by moving the handle 29 axially before turning it. Also the member 16 may be reset without waiting for the preselected period to elapse by moving the member axially. A friction clutch in the gear train also permits this as well as allowing the gear 25 to move without the escapement when the spring is being loaded. The operating member is held against a fixed stop 23 by the spring 20 which is partly loaded in the zero position of the operating member 16.
