Abstract: 536,575. Telegraph exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HAIGH, L. B. Aug. 9, 1939, No. 22980. [Class 40 (iii)] Calling subscribers are charged either by means of ticketing apparatus or by meters in accordance with their identity and that of ,the-called party. In one arrangement, Figs. 1 and 2 (not shown), a translator switch hunts for a marking applied jointly by a switch for identifying the calling party and by the second and third registers of a three-digit register controller, 'the first register of the latter selecting a particular wiper, and controls the transmission to the ticket printer of a digit indicative of the proper charge. In a modification, Fig. 4 (not shown) and Fig. 5, subscribers are given four-digit numbers indicative of their geographical position, in addition to the directory numbers, in accordance with the co-ordinate scheme set out in Fig. 3. In this case a switch CNS which hunts for a position indicative of the wanted line applies four markings in succession in one of the banks of sending switch SM6 in accordance with the wanted party's geographical. number and the switch IFS applies similar markings in another bank of the sending switch at the same time in accordance with the calling party's geographical number. The arrangement is such that impulses are sent to the ticket printing apparatus when the sending switch reaches one marking and are stopped when it reaches the other. The total number of impulses sent to the ticket printer is the sum of the differences, neglecting sign, between the respective digits of the two geographical numbers and this number gives an indication of the approximate distance between the two parties and consequently of the appropriate charge. Coordinate schemes, using 3 or more 'than 4 digits are also referred to. The circuit arrangements, apart from those concerned with the charge assessing apparatus, are the same as those described in Specification 513,205. Specification 513,285, [Group XXXIX], also is referred to.

Patent GB-248414-A (GB)
Title: Improvements relating to processes involving exchange reactions and particularly to the softening of water by zeolite-like bodies
IPC: B01J47/10
Filed: 1924-10-01
Abstract: 248,414. Higgins, E. B. Oct. 1. 1924. Purifying liquids.-In softening water by base exchange material and for other purposes involving exchange reaction, the exchange material is maintained in a state of suspension by the liquid to be treated flowing upwardly at a speed equal to or greater than the natural rate of fall of the coarsest particles of the exchange material so that the exchange material is maintained stationary or travels slowly upwards. In apparatus where the exchange material is maintained stationary a cone-shaped vessel is employed with vertex downwards at which the treated liquid and also the brine for regenerating the exchange material enters. The rate of flow of liquid is adjusted so that the speed of the liquid at the narrow end is sufficient to prevent the largest particles falling and the speed at the upper end is such that the smallest particles will fall. An expanded part is provided at the top having an outflow pipe. If heavier particles are used the cone is narrower to increase the speed of the liquid flow. The apparatus may be used open or under pressure. The taper of the conical vessel may be increased to allow the use of an exchange material having a greater diversity in the dimensions of the particles. The vessel may be cylindrical, with conical extensions at the top and bottom to give the required variation in the speed of flow. In an apparatus for a continuous process a pair of receivers 14, 15 of less diameter than the throat 8 of the vessel 1 are connected with the base of the vessel 1 by valves 16, 17. The exchange material when exhausted is allowed to fall from the vessel 1 through the corresponding valve into one of the receivers,- where it is regenerated by brine introduced by a cock 20 and exhausted through a cock 18. Simultaneously, regenerated exchange material is carried up into the vessel 1 from the other receiver by the treated liquid introduced through a valve 6b where it is maintained above the throat 8 by the liquid flow through the receiver. Fig. 6 shows an apparatus in which the exchange material travels slowly upwards in the tube 1 and the treated liquid passes through an injector 13, drawing exchange material from a container 22, and passes with the exchange material into a vessel 29 where the exhausted exchange material collects. The exhausted exchange material is conducted back to the container through a specially chamfered valve 30, to give small resistance to its passage, and through a further liquid column 31, midway in which is an inlet 5 for upwardly flowing brine which regenerates the exhausted material as it falls. The exchange material is then washed by upwardly flowing water passing into the container 22 from a pipe 32. The process may be applied to cases wherein reversible absorption takes place, e.g., removing iron in solution from water by manganese zeolites.

Abstract: 637,469. Determining physical qualities of materials. PHILLIPS, R. S., and BURNS, Ltd., J. Aug. 21, 1947, No. 23238. [Class 37] Apparatus for measuring the moisture content of a solid material comprises a metal rod 7 supported centrally in and insulated from a metal cylinder 1, the intervening space being filled with a weighed amount of the solid material 11 covered by a quantity of liquid 12 of the same dielectric constant as the material 11 when dry, the resultant dielectric constant being an indication of the moisture content of the material 11.. A mark 9 on the tube 1 indicates the maximum height of the material 11, and a further mark 10 indicates the minimum height of liquid to be used. Facilities are provided at the base of the tube 7 for attaching terminals to the electrodes. The liquid to be used should not dissolve the material tested, or be miscible with water and should have a density smaller than the material tested. The capacity of the device and that of a capacitor 27 calibrated in moisture content together determine the frequency generated by a Hartley oscillator. The capacitor 27 is adjusted until the generated frequency reaches the value for which a bridge 31 to 38 coupled to the oscillator is balanced.
