Title: Improvements in or relating to apparatus for supplying ringing current in automatic telephone-exchange and like systems
IPC: H04M19/02
Filed: 1951-11-29
Abstract: 699,941. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 29, 1951 [Dec. 2, 1950], No. 28023/51. Class 40 (iv). [Also in Group XL (c)] In an automatic telephone system of the kind in which the talking connection to a called line is established by a selector comprising a discharge tube of which an output electrode is coupled with the line and means is provided to render a discharge path to that electrode conductive when the line is called, ringing current is supplied to a called line through a discharge path of an additional discharge tube which is controlled in accordance with the voltages of the output electrode and of a conductor of the line so that the discharge path of the additional tube is conductive for part at least of each period of the ringing current if the discharge path of the first tube is conductive and the line loop is not closed. In the simplest form (Fig. 1), the additional tube BB is normally extinguished but when the path OB becomes conductive (line L selected) the potential of point Q drops and the potential difference between the anode a and cathode k exceeds the starting voltage of tube BB for part of the ringing cycle of generator WG. Tube BB may extinguish during the negative half-cycles but will fire again for the positive. On the reply of the called party the potential of Q increases and tube BB is extinguished. In the embodiment of Fig. 2 the discharge path OB is coupled to the line L1, L2 by a transformer and the tube BB fires when the voltage difference between the starting electrode f and the cathode k exceeds a critical value. When the line is selected current flow through R4 raises the potential at Q and tube BB fires, but on the reply of the called party the potential of k increases and that of f decreases so that tube BB is extinguished. In a modification (Fig. 3 not shown), the tube BB has two starting electrodes, one connected to Q and the other to L1. The cathode k is connected to L2 and the connection from L2 via R6 to Q is omitted. Generation of ringing current, Fig. 4. The tube BB which is a gas-filled triode has its anode and cathode connected to L1 and L2 respectively, and its grid to point Q. When the line is selected the potential of Q rises, BB conducts and discharges C1 rapidly whereupon BB becomes non-conductive. C1 is recharged slowly through R2 and R3 and the tube BB again conducts and so on. On the reply of the called party the potential across BB is reduced so that BB remains cut off.

Abstract: 1,219,337. Seaming non-metallic sheet material. INTERNATIONAL PAPER CO. 14 June, 1968 [11 Oct., 1967], No. 28415/68. Heading B5K. [Also in Divisions B2 and B8] A method of closing a container formed from card coated with plastics material, comprises applying a wetting material to selected portions of selected panels and then heat-sealing the selected panels together before there is substantial loss of the wetting material from the selected portions. The resultant seal is inhibited in the region of the selected portion to facilitate the opening of the container. As shown, a gable top container has wetting material applied to the edges 90, 91 of panels 60, 61 before heatsealing. The wetting material penetrates the exposed, non-coated edge of the card. Dried, sealing-resistant coatings 83-88 may also be applied to both sides of panels 60, 61 and to the insides of panels 45, 46. After closure of the container with conventional heat-sealing equipment, the formation of the pouring spout shown is thus facilitated. The wetting material may be water containing a wetting agent to facilitate penetration of the card fibres along edges 90, 91. Alternatively, a thickening agent may be added to the water. Examples of suitable agents are given.

Abstract: 1,105,333. Multistage data shift register. WESTERN ELECTRIC CO. Inc. 6 July, 1965 [6 July, 1964], No. 28502/65. Heading G4C. [Also in Division H3] A control circuit for shifting bits in a multistage data register, comprising a plurality of gating path means individually connecting each stage of said register to other stages of said register each a different predetermined number of positions away from each said stage, means for sequentially operating said gating path means in accordance with the number of positions by which bits in said register are to be shifted, the number of operations being less than the number of positions shifted if the latter is greater than one, and means for simultaneously operating all selected gating path means connected between stages separated by the same number of positions. As described each stage is connected to stages situated 1, 4, 7, 8 positions to its right and left including corresponding positions for rotation and for abbreviated rotation wherein only bits situated in stages 6 to 21 inclusive are shifted. A maximum of three shifts is required to move the bits to any position. Briefly, in operation, the control (Figs. 6 to 21, not shown) comprises a counter (Fig. 6) receiving the number of shifts required, which, in combination with three timing pulses determines the number of shifts to be applied in each of the three operations. The instructions for right or left shift, rotation or abbreviated rotation are also produced (Figs. 6, 7, 10). These instructions plus the false outputs from the transistor flip-flops (Division H3) forming the memory (Fig. 25D, not shown) open the necessary gates to transfer the information the required number of places. The flip-flop states can be changed by suitable pulses on the lines S-0 and S-1 or by appropriate pulses on lines SP or SPS and N-0 on SP or SPS and N-1. The lines S-0 and S-1 are complementary and coupled to external apparatus and are used to write in new information. The N-0 and N-1 are complementary and are the inputs to each stage from the appropriate registers connected by the control circuit (Figs. 8, 9, 12, 13, 16, 17, 19, 20, 21, not shown). The SP line carries a shift pulse and is connected to stages 6 to 21 inclusive, the pulse being applied for all shift orders. The SPS line also carries a shift pulse and is connected to stages 1 to 5 inclusive and stage 22, the pulse not being applied for an abbreviated rotate order. In order to change state both an SP or SPS pulse and a N pulse must be present, the flip-flop being changed at the end of the pulse.
