Abstract: 721,597. Sleeve couplings; two - part couplings. SHARDLOW ELECTRIC WIRES, Ltd., and JONES, P. July 18, 1952 [June 27, 1951], No. 15299/51. Class 38 (1). Means for connecting a coaxial cable to another similar cable or a plug or socket connector comprises a metal sleeve 1 having a longitudinal slit 2 at least at one end and a number of transverse slits 3, the slit 2 preferably being off-centre in relation to the slits 3. For joining a pair of cables the sleeve 1 is slitted at both ends, Fig. 1. The outer insulating covering of the cable is removed to expose a length of the metal cable screen and the screen and interior insulation are cut back to expose the central conducting core. The sleeve 1 is slipped over one of the prepared cable ends and the two cores joined by a metal tube crimped or soldered thereto. The sleeve 1 is positioned so that the core joint is in the centre and the tongues 4 are crimped down to engage the cable screens and, preferably at the ends of sleeve to grip also the insulating cable coverings. The sleeve is finally covered with insulating tape. In the construction, Fig. 3, the sleeve 1 is slit only at one end and the other end constitutes a plug connector 5 having a tubular contact pin 6 mounted in an insulating block 7 and in which the cable core is soldered.

Title: Device for correction of synchronisation faults for a switchable data transmission network operating on a time-sharing basis
IPC: H04J3/07
Filed: 1973-03-30
Abstract: 1389640 Multiplex pulse signalling P PERON and M REVEL 30 March 1973 [31 March 1972] 15441/73 Heading H4L  Normal, advanced and delayed input signals for a t.d.m. exchange are available from respective shift registers 6N, 6A, 6R in order to compensate for lead or lag of the local clock relative to the distant (sending) clock. Return to the normal register is facilitated by transmission of "blank" words. Each of the eight periods T 0 -T 7 , Fig. 3, not shown, of the received signal has four time slots the first being a sync word # 0 , # 1 , &c. The input signal at 1 is gated initially to the shift registers 6A, 6N, 6R by a routing circuit 10 controlled by sampling pulses (h 1 , h 2 , h<SP>1</SP>, H and h, Figs. 2a, 2b, not shown) generated by a sync detector 2, a control circuit 4 and the clock 3. Lag or lead by one time slot of the local clock 3 is manifested by repetition or omission of a sync word, and this is detected by the sync word detector 2 and the control circuit 4 which governs logic circuitry 9, 15 to select the output of the appropriate shift register by means of gates 153A, 153N, 153R. To permit return to the normal shift register 6N after an advance or delay routine, the blank words containing neither data nor synchronizing words are inserted at intervals in the transmitted signal, and when one is detected at 13 the circuit 15 initiates return to the shift register 6N, as this can now be done without loss of sync or data. A time lag 14 ensures that only one blank word per period is counted. The output from the appropriate shift register 6A, 6N, 6R goes to whichever one of a plurality of buffer registers 11 1 -11 m  Fig. 1, not shown, corresponds to the operative time slot 1-32 in the 8-period signal T 0 -T 7 . To direct the signals to the correct buffer, addresses are generated at 18 to control appropriate gates. These addresses however must be-stepped backwards or forwards according to which register 6A or 6R is being used, and to do this a comparator 8 detects when a "jump" counter 12 responsive to the control circuits 4, 9 and to the blank word detector 13, is out of step with an address counter 5 responsive to the logic circuit 7 controlled by clock 3 as well as by the received signal.

Title: Indicating device particularly for radio direction finding apparatus
IPC: G01S1/02
Filed: 1940-10-24
Abstract: 542,564. Radio direction finding. STANDARD TELEPHONES & CABLES, Ltd. Oct. 24, 1940, No. 15655. Convention date, Oct. 25, 1939. [Class 40 (v)] [Also in Group XXXVI] In a device for indicating cyclic current variations, particularly those produced by a rotating loop antenna, the cyclically varying current energizes an electromagnet rotated in timed relation therewith, an indicating magnet being arranged to respond to magnetic poles induced in the electromagnet. Receiving apparatus for direction finding is shown in Fig. 1 and consists of a loop 5 rotated by a motor 6. The currents induced in the loop are detected and rectified by a receiver 7 and fed to an indicator 8, the moving parts of which are rotated by a driving means 9 which is driven at a speed synchronous with the speed of rotation of the loop or at a multiple thereof. the shaft 10, Fig. 2, of the indicator carries an insulator 11, a counterweight 12, and an electromagnet 13 with core 14. As the electromagnet is rotated fields are set up in a stationary disc 15 of copper or other non-magnetic material. A permanent magnet 16 takes up a position in agreement with these fields and thereby rotates a pointer 17 to indicate the signal direction on a dial 18. The disc 15 also serves for damping the magnet 16. Alternative damping means may be used such as a disc 20 and permanent magnet 21, in which case the disc 15 may be dispensed with. Other devices responsive to the magnetic poles induced in the disc 15 may be employed, e.g. relays controlled by magnets placed around the disc, the magnets being responsive to maximum magnetic poles of a particular polarity. Current is led in to the electromagnet winding 13 through the shaft 10 and a contact 19 engaging the disc 15. If the electromagnet 13 is rotated at a speed synchronous with the loop speed there is a 180 degrees ambiguity in the indication given. This may be avoided by driving the electromagnet at twice the speed of the loop, or by combining the loop antenna with a sensing antenna and rotating the electromagnet at the same speed as the loop.

Title: Improvements in or relating to edge type filter elements and methods of making the same
IPC: B01D25/00
Filed: 1954-05-28
Abstract: 756,610. Filters. PUROLATOR PRODUCTS, Inc. May 28, 1954 [June 26, 1953], No. 15823/54. Class 46. [Also in Group XXII] A metallic filter unit 10, Fig. 2, comprising a hollow open-ended cylinder and being one of three kinds-namely a ribbon having projections on one wide face, wound helically so that the wide faces are normal to the axis of the cylinder so formed and supported on a fluted drum; a ribbon similarly wound, coated with fusible material and subsequently heated and cooled to render the element self supporting and the fluted drum unnecessary; and a stack of rings or washers provided with raised portions-is mounted between end pieces and connected to a suction line 19, and sprayed (20) with a dispersion of metallic dust in a volatile or partially-volatile liquid dispersant. Metallic dust, ranging in size from 10 to 40 microns, is dispersed in a liquid dispersant such as alcohol, acetone or carbon tetrachloride. A powder of rock wool or glass may be mixed with the metal powder. As an alternative to spraying the unit may be dipped in, or brushed with, the dispersion. In all cases excess is wiped off, and the unit is allowed to stand for a time sufficient to allow the volatile portion of the dispersion to evaporate. It is then subjected in an oven to a sintering temperature so that the dust is sintered and attached to the unit. The extent of the ensuing reduction of filtering interstices 13b, Fig. 8, may be controlled by regulating the thickness of the coating, by varying the percentage of dust and by using dispersants of different viscosities. In a second method the dispersant comprises a lacquer consisting of a non-volatile resin such as lac and a volatile solvent such as methyl alcohol. On completion of the coating step the unit is heated in an oven to dry the coating by evaporation of the volatile portion. The unit is next transferred to an oven maintained at a higher temperature where the non-volatile portions of the lacquer are burned off, leaving charred skeletal remains, intermingled with the metallic dust, and voids. The unit is finally subjected to a sintering temperature. In a third method the percentage of metal in the dispersion is relatively high, and the dispersant is that used in the second method. After application of the dispersion to the unit the latter is subjected to electroplating in a bath of e.g. alkaline copper sulphate solution at a current density of e.g. 100 amps. sq. ft. for a time sufficient to effect a plating action equivalent to 2500 amp. minutes per square foot. After washing, the unit is heated at a temperature of from 300‹ to 400‹ F. There results a porous coating consisting of electroplated dust particles 21b, charred particles 23b of the lacquer component and voids 24b, Fig. 8. One form of stacked ring unit to which the invention may be applied is shown in Fig. 13. Specification 665,149 is referred to.

Abstract: 591,779. Furnace hearths and causes. SOC. ANON. POUR L'INDUSTRIE DE L'ALUMINIUM. Aug. 21, 1944, Nos. 15959 and 15960. Convention dates, Aug. 23, 1943. [Class 51 (ii)] [Also in Group XXXVI] In a cell for electrolytically refining aluminium by the three layer process the base 5 constituting the electric connection to the anodic layer 2 (consisting of an alloy of aluminium with a heavy metal or metals, e.g., copper, nickel or silver) is made by pouring and afterwards calcining an artificial carbon mass. C'rushed coke with coal tar as binder at 140‹-200‹C. is a suitable mixture. A vertical layer 6 forming an outer lining to the refractory insulating walls 1, which are preferably of magnesite, may be similarly formed by pouring an artificial carbon mass and calcining. The layer should extend at least as high as the upper surface of the anode layer and as low as the upper surface of the carbon bottom. Escape of metal or electrolyte due to fissures in the walls 1 &c. is thereby prevented. The space above the vertical layer may be filled with a rammed refractory mass. The vertical layer may alternatively be disposed within the walls 1 when thick. The upper surface of the base 5 is preferably made slightly concave, e.g., by pressure with a template while still pasty or alternatively by means of a hammer and chisel after solidification. The artificial carbon mass may before calcining be subjected to mechanical vibration of high frequency, preferably over 6000 per minute, in accordance with Specification 561,496; this treatment is preferably effected before pouring but may be done after pouring and before substantial solidification has taken place. The metal of the anode layer 2 may be introduced through a filling shaft or shafts 7. Specification 581,625, Swiss Specification 190,775 and French Specification 821,124 also are referred to.

Abstract: 1386663 Alpha methyl styrene block copolymers STAMICARBON NV 6 April 1972 [14 April 1971] 15983/72 Heading C3P A block copolymer of formula B-X-C, A-B-X-C or A-X-B-X-C or like structures are obtained by an anionic polymerization process in which the X blocks are controlled to 1 to 100 monomer units. Block B is a conjugated diene polymer which may be a copolymer with a vinyl aromatic compound, X is a block of styrene or ring-substituted styrene monomer units, C is an alphamethyl styrene polymer block which may be a copolymer with a minor amount of a vinyl aromatic compound. A is a non-elastomeric block, e.g. of alphamethyl styrene. The process may be carried out by initially adding all the monomers to the polymerization medium and controlling the course of the reaction, e.g. by noting the commencement of styrene polymerization and of the α-methyl styrene polymerization upon the appearance of yellow and red anion colorations respectively. Alternatively a simple sequential procedure may be used. In examples isoprenestyrene-alpha methyl styrene block terpolymers are obtained by polymerizing such a monomer mixture in pentamethylheptane in the presence of sec-butyl lithium with the final stage being performed in the presence of added tetrahydrofuran and at low temperatures; in a similar example the alphamethyl styrene is added after formation of the initial two blocks; in another case, 1,4-dilithio-1,1,4,4-tetraphenyl butane was used as initiator to form a C-X-B-X-C polymer; in a further case the solvent is cyclohexane and the initiator the reaction product of secbutyl lithium with, successively, styrene, divinylbenzene and styrene, and having a functionality of 3À8.

Abstract: 696,718. Converting. BRITISH THOMSONHOUSTON CO., Ltd. July 9, 1951 [July 22, 1950], No. 16232/51. Class 38 (ii). A control system for an ignitron 1 having a holding anode 4 and a control grid 3, in addition to the usual igniter 6 and main anode 2, comprises valves 19 controlling, respectively, the igniter and grid potentials, the grids of the valves being fed in push-pull with a peaky control signal S which causes the valves to conduct alternately and effect alternate conduction of further valves IFT, GFT in the igniter and grid circuit, respectively, of the ignitron. The arrangement is such that upon conduction of valve IFT a condenser IFC (previously charged from a source 8) discharges through the igniter 6 and initiates ionization within the ignitron; ionization is then maintained by the holding anode, which is connected to a source 12, but negative bias on the control grid prevents conduction to the main anode. When valve GFT conducts (later in the signal cycle) the grid bias is overcome by an opposing voltage from a source 14 and the discharge passes to the main anode 2. To prevent application of the " opposing " grid voltage in event of anode 4 failing to hold the initial discharge, the cathode circuit of the valve 19 which controls valve GFT includes the discharge path between the holding anode and cathode of the ignition.
