Abstract: 612,594. Metal vapour converters. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. May 29, 1946, No. 16363. Convention date, July 19, 1945. [Class 39 (i)] A metal tank high-power mercury vapour polyanodic current converter has an annular cathode K whose effective area is limited on its outer side by a refractory insulating ring a, e.g. quartz, and towards its centre by a cup a<1> of the same material, convex side upward. The metal plate p forming the bottom of the cathode carries centrally a core n to limit the expansion region of the mercury. An internal air-cooling system comprises a cluster of tubes T whose inlet ends e are fixed to the anodecarrying lid P, the other ends s opening into a central conduit R which may house a fan V for maintaining the cooling current of air flowing in parallel through the tubes T. This flow may be in series with or independent of the aircooling arrangements m for the external walls of the tank.

Abstract: 736,917. Filters. FRAM CORPORATION. June 16, 1953, No. 16573/53. Class 46. A filter element comprising a plurality of shaped porous fibrous paper members secured together is formed by bonding one member, having a thermoplastic and a thermosetting resin uniformly distributed throughout its fibres by impregnation with an aqueous dispersion or preferably solution of the resin, to another similar member by pressure with or without heat, and further bonding the members by heat-setting the resin. In Fig. 3 the outer peripheries of two'sheets 10 and 11 are sealed by a pressure of 1000 lb. p.s.i., leaving a slight groove at 13 and rib at 12. The sheets are held apart at their centre by a spacer 15 having staggered filtrate-discharge grooves 18, 19 and formed of resin or the like. A number of such units is sealed together, with or without the interposition of washers 22 of the same material as the cells, to form the element shown in Fig. 1. In Fig. 10 discs 42, Fig. 12, are assembled in staggered formation, three such discs forming a unit, and caused to adhere between flanged endplates 48, 49, by the application of a pressure of 100 lb. p.s.i. at a temperature of from 100 to 350‹ F.

Abstract: 903,019. Adjusting radio-tuning controls. COMMUNICATIONS PATENTS Ltd. Aug. 19, 1960 [May 19, 1959], No. 17024/59. Class 40 (5). In tunable electrical apparatus comprising a number of tuned circuits, e.g. 3, 4, Fig. 1, each of which when tuned requires to be set to a different position, each of the circuits is driven by an individual servomotor 9, 10, respectively. The positions taken up by each servomotor are determined by control voltages from corresponding potentiometers 11, 14, respectively, which are controlled from a single shaft 16 and have tracks so graded as to bring the servomotors to the desired relative positions. The potentiometers may be located at a remote point or may be replaced by switch control. In a remote control arrangement for a radio transmitter oscillations from a master oscillator 18, Fig. 2, at the control point are transmitted over a line 19 to the transmitter, in which they are applied to a mixer 21. Oscillations from a local oscillator 20 are also applied to the mixer 21 and the beat frequency is fed to a detector 22 feeding a servomotor which tunes the local oscillator 20 so that a predetermined beat frequency is produced. The position of the servomotor is thus controlled by the remote master oscillator 18 and it may be used to adjust a number of potentiometers 25-31, each producing a separate control voltage for a corresponding servomotor 32-38 respectively adjusting a separate tuned circuit of the transmitter. Circuits so controlled include a frequency-doubler 40 and modulator 41 which may be modulated from either of the sources 44, 45 as chosen by switch 43. The switch 43 may be remotely operated by pulses over the line 19. The modulator is followed by amplifiers 46, 47, 48 and tuned aerial circuits 52. Provision may also be made for the servomotors 37, 38 to automatically adjust the aerial circuits 52 to compensate for changes due to climatic or other causes. The tuning of the various circuits may be carried out in two steps, the ganged potentiometers being roughly tuned under control of a resistance-capacitance frequency-discriminating circuit and simultaneously accurately tuned by means of an accurate frequency-measuring device.
