Abstract: 786,677. Yarn tensioning means. DEERING MILLIKEN RESEARCH CORPORATION. Aug. 16, 1955 [Aug. 18, 1954], No. 23606/55. Class 120(2) A yarn tension regulator comprises a pivoted yarn-engaging member which is urged tawards a second yarn-engaging member by a longitudially resilient, inflexible strut which is in compression between the pivoted member and a support adjustable in position relative to the second member for the purpose of varying the degree of compression of the strut, the strut being held in compression by engagement of pivot stems forming its ends in pivot seats. on the support and on the pivoted member. The invention is shown applied to a two for one twister and the numeral 10 designates. a tubular housing supported by  the platform of the twister. This housing. 10 carries a cap 12 provided with a central bore 14 through which yarn from a yarn supply package is passed downwards through the tension regulator gerierally indicated at 16. The tension regulator 16 comprises a fixed yarn engaging member comprising a series of parallel bars 18, 20, 22, 24 and 26 and a pivoted yarn engaging member consisting of a pivoted arm 30 and a series of bars 32, 34, 36 and 38. The lower end of the arm 30 is bifurcated into two legs 40, 41 each having their extremities formed into knife edges 42, 43 which rest in V-shaped grooves. of the upper end of a cylinder 44 positioned in the housing 10. The tension regulator is also provided with a preliminary tension array comprising a pair of matched plates 48 and 50. Positioned on the arm. 30 about midway of its length is a block 58 in which there is formed a pivot seat 64 adapted to receive one end of the longitudinal resilient inflexible strut generally indicated at 80, the other end of this strut being housed in a similar pivot seat in a support 76 which can be moved up and down the housing 10 by a collar 70. Thestrut 80 comprises a tubular female element 82 and a matching male element. 84 which is adapted to telescope into the member 82 and a helical compression spring 92 surrounding the two elements and confined between flanges 55 and 88 thereby urging the longitudinal extension of the strut 80. Extension of the strut is. limited by an external shoulder 96 on the male element engaging with an internal lip 94 on the inner end of the female element. A handle 98 is provided on the arm 30 for the purpose of separating the bars of the tension regulator for threading- up. The arrangement is such that the longitudinal axis of the strut 80 intercepts the longitudinal axis of the arm 30 at an angle and since this angle increases as the bars 32, 34, 36 and 38 move further between the bars 18, 20, 22, 24 and 26 the rotational torque inserted on the arm 30 increases as the movable yarn engaging member more closely approaches the fixed yarn engaging member.

Title: Improvements in cascode circuits
IPC: H04N5/44
Filed: 1951-10-10
Abstract: 703,946. Valve amplifying circuits. STANDARD COIL PRODUCTS CO., Inc. Oct. 10, 1951 [Feb. 20, 1951], No. 23618/51. Class 40 (6) In a television receiver covering two frequency bands, the coupling between a grounded cathode triode and a grounded grid triode is arranged to be resonant in each of the two bands. The circuit described is of the cascode type covering frequency bands 54-88 and 174-216 magncycles. A balanced input is applied over reversed bifilar coils 14, 15 to input coil 17 feeding grounded cathode triode 11, the anode circuit being connected to the cathode of grounded grid valve 22 over coupling capacitor 26 and low inductance coil 27. The cathode circuit of valve 22 is completed over inductor 28 and bias resistor 29 while the heaters are fed through inductors 32, 32a, and the output is taken from tuned circuit 81, 84. Over the lower frequency band the stray capacity resonates broadly with the inductors 23, 28 due fo the heavy damping presented by the input circuit of valve 22 and inductor 28 is of lower Q than inductor 23 to maintain a broad band-width. Over the higher frequency band the inductors 23, 28 present a high impedance and the inductor 27 is made to series resonate with the capacity between the cathode 21 and heater 33 at the upper end of the band. This circuit is therefore capacitive below this frequency and forms a tuned circuit with coils 32, 32a to present a substantially constant impedance over the band. Heater lead inductors may be used, Fig. 9 (not shown), when the heaters are connected directly in parallel.

Title: Improvements in and relating to arc furnace control systems
Inventor: STEELE OWEN STEVENSON
IPC: H02P27/02
Filed: 1953-09-01
Abstract: 761,071. Automatic control systems for arc furnaces. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 1, 1954 [Sept. 1, 1953], No. 24161/53. Class 38 (4). In an A.C. arc furnace the ratio of arc voltage to current is maintained constant by automatically controlling, through saturable reactors, an A.C. motor adjusting electrode position. In Fig. 1 direct voltages respectively proportional to arc voltage and current of a furnace electrode are produced across resistors VR1 and R3 through rectifiers W2 and W1. The two voltages are opposed and when the ratio of arc voltage to arc current has the desired value, zero voltage is applied to a D.C. amplifier E. If, however, the ratio deviates from the desired value amplifier E produces an output, of polarity corresponding to the sense of the deviation, which, through a rectifier W4 or W3, energizes the control windings of saturable reactors A1 and A2 or B1 and B2, thereby selectively reducing impedances in the supply lines to a three-phase motor M so that it runs in the appropriate direction to correct the deviation by adjustment of the electrode position. A similar arrangement in which electrode position is controlled by a single phase reversible capacitor motor is described. The saturable reactors and hence motor M may be controlled manually by a controller C. Amplifier E may be dispensed with and the difference voltage utilized directly to energize the saturable reactor control windings.

Title: Improvements in or relating to the preparation of titanium nitride
IPC: C01B21/076
Filed: 1953-09-01
Abstract: Titanium nitride having a particle size of 0.01 to 1.0 micron is produced by reacting anhydrous titanium sulphide having a particle size of less than 300 microns with anhydrous ammonia gas or a corresponding mixture of hydrogen and nitrogen at 800-1400 DEG C.  An excess of ammonia, e.g. 100-200 per cent, is preferably employed. The reaction may be carried out in a static or fluidized bed.  An electrically heated reaction tube of "Alundum" (R.T.M.) may be employed.  The reaction tube may be rotated so as to ensure intimate contact between the titanium sulphide and ammonia gas.  The hydrogen sulphide produced as a by-product in the process together with hydrogen and nitrogen may be used to produce further titanium sulphide, by reaction with titanium tetrachloride, which may then be used to produce further titanium nitride, by reaction with ammonia supplemented by the by-product hydrogen and nitrogen.

Abstract: 1,116,534. Brushes for electrical machines. SOCIETE LE CARBONE - LORRAINE. 8 June, 1965 [8 June, 1964], No. 24297/65. Heading H2A. [Also in Division B5] An electrical brush material comprises layers of carbon or graphite tissue laminated together by a cured, resin, wherein the electrical resistance of the material is 50 to 100 times greater in the direction perpendicular to the layers than in the direction of the layers. As described, the layers of tissue are formed by carbonization and/or slow graphitization of tissues or fibres of regenerated or unregenerated cellulose, mercerized cotton, viscose or polynosic fibres as described in Specification 1,110,596 and the resins used are furanic phenolic or epoxy resins applied to the tissue layers by immersion, impregnation, spraying, or a brush. In an example, layers of tissue are coated by immersion in a bath of phenolic resin in alcoholic solution. The coated layers are rung between rollers and dried. A number of sheets cut from the dried layers are then stacked in a heated matrix at the curing temperature of the resin to form a laminate which is then carbonized by treatment at 1200‹ C. and/or graphitized at 2800‹ C. to carbonize and/or graphitize the resin. After carbonization and/or graphitization the laminates may be impregnated with a molten metal selected from copper, silver, or their alloys, or may be impregnated with polyester resins, e.g. a mixture comprising 70% by weight of a polyester based on diethylene glycol, phthalic anhydride and maleic anhydride and 30% by weight of monomeric styrene. The laminate is alternatively impregnated with a lubricant, e.g. molybdenum disulphide, tin sulphide or polytetrafluorethylene, or an adjuvent such as hygroscopic or non-hygroscopic metallic salts, or polyester resins copolymerized with arylvinyl monomers.
