Title: Improvements in or relating to television and like systems
IPC: H04N5/08
Filed: 1935-10-08
Abstract: 463,971. Television. BAIRD TELEVISION, Ltd., and MERDLER, L. R. Oct. 8, 1935, Nos. 27819, 29311, and 29864. [Class 40 (iii)] Synchronizing signals occur across an impedance R1, R3 in the cathode lead of a separating valve V1 in reverse polarity to television signals across an anode impedance R4. The impedance in the cathode lead consists of pure resistances R1, R2, R3 in series, and the line-frequency and picture-frequency synchronizing signals are derived from the mutually exclusive resistances R1, R3. An anode-bend rectifier V2 is interposed between the resistance R1 and a higher-frequency generator V4 of the kind described in Specification 435,196. The rectifier V2 and its associated circuit are decoupled to a local earth lead L which is maintained positive relatively to the grid of the rectifier to provide the necessary bias. When the synchronizing impulses are to be developed across a load impedance effectively in the grid circuit of a scanning-oscillator, the impedance, or part of it, is in the cathode lead of the separating-valve and is shunted, if at all, by a much higher impedance.

Abstract: 355,977. Variablespeed friction gearing. ROBERTSON, J. H., 1, Albemarle Street, Piccadilly, London. Sept. 19, 1930, No. 28071. [Classes 80 (i) and 80 (ii).] In variable-speed friction gearing of the kind in which a driven friction face wheel c is moved eccentrically with respect to a driving coned disc a, the frictional engaging pressure is applied to one of those numbers by hydraulic means. In the arrangement shown, wheel c is carried by an arm e pivotally carried by a sleeve e<1> slidable upon a fixed pivot shaft f. Sleeve e<1> is urged towards disc a through thrust bearing k by a piston j in a fixed cylinder i fed by oil from a pump g driven by the engine, say, on a vehicle. The oil pressure in feed, pipe h<1> is controlled by a spring-pressed ball l governing the overflow to a waste pipe h<2>, and a manual or automatic control applied to handle m<1> of valve m, by adjusting the areas open from the pump to pipes h<1>, h<2>, regulates the actual thrust in bearing k. The angular movement of arm e may shift handle m<1> or change the tension of spring l<1>.

Title: Means for driving false twist spindles
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/06
Filed: 1964-07-08
Abstract: 1,116,833. False-twisting apparatus; crimping; doubled yarns. KLINGER MANUFACTURING CO., Ltd. 8 July, 1965 [8 July, 1964], No. 28140/64. Headings DID, D1F and D1W. A head for supporting and rotating at least two false-twist spindles comprise two horseshoe magnets disposed side-by-side, like poles of the magnets being joined by pole pieces e.g. 225 between which is arranged a tracked wheel 217; each pole has tips e.g. 240 of reduced dimensions corresponding in number to the falsetwist spindles employed, and each spindle e.g. 243 is arranged with an end adjacent a tip on each pole piece. The wheel 217 is an inverted cup with two tracks. The tracks extend outwardly beyond the tips and each spindle may have a centering member between the tracks or at its ends. As shown, there are three spindles; when there are two spindles they may be close or separated over an arc of 20 or 90. Two associated spindles in the head could simultaneously process two yarns passing through the spindles in the same direction or in opposite directions. One yarn may pass first through one spindle in one direction and then through the associated spindle in the opposite direction to produce a yarn having superimposed S and Z twists. When such a yarn is heated a non-torque crimped yarn is produced. To produce two-fold yarns comprising a yarn of S-twist combined with one of Z twist, adjacent heads are rotated in opposite directions; all the yarns pass through the spindles in the same direction, and yarn from one spindle is combined with a yarn from a spindle in an adjacent head. The head may have a guard enclosing the spindles with a cavity for each spindle to prevent the spindles moving out of the range of the magnets. For ease of threading-up, all the spindles are arranged on the opposite side of the head from the driving-belt. That part of the spindle which contains the twisting-pin extends past the corresponding tip to offset 'the fact that the slot in which the pin is mounted reduces the capacity of the end part of the spindle to pass magnetic flux. A sleeve of hard-wearing material may encircle the driving member of the wheel.

Abstract: 1359145 Silicon carbide whiskers DEFENCE SECRETARY OF STATE FOR 13 Sept 1971 [12 June 1970] 28492/70 Heading C1A In producing silicon carbide whiskers by maintaining a silicon-containing vapour and a carbon containing vapour at a temp. of at least 1100‹ C. in a reaction zone in the presence of a necleating material (i.e. a solid material in the whisker forming zone on which it is intended that the SiC whiskers should be deposited) so that SiC whiskers are deposited on said nucleating material, a sufficient amount of an iron containing vapour is provided in the reaction zone so as to supersaturate the zone with respect to iron. The concentration of iron may be maintained by passing an iron containing vapour into the reaction zone from a source which is remote from the zone. This vapour is preferably supplied at a rate substantially equal to the rate of consumption of iron in the whisker forming reaction. The iron containing vapour may be formed by passing a reactant in the whisker producing reaction over a particulate source of iron immediately before introducing the reactant into the reaction zone. Alternatively chlorine or hydrogen chloride gas may be passed over the source of iron and the resulting vapour passed into the reaction zone. The source may be heated to a temp. 30 to 150‹ C. below the temp. in the reaction zone. Another method of introducing Fe containing vapour into the zone is to introduce finely divided solid iron, or iron containing compound or a solution or dispersion of an iron compound which yields the required concentration of Fe vapour at the temp. of the reaction zone, into said zone. The amount of Fe introduced may be up to 5% by wt. of the total wt. of vap. phase silicon and carbon in the reaction zone, e.g. to produce a vapour press. of iron of at least 10<SP>-6</SP> atm. (at 1350‹ C.). The reaction zone is preferably maintained at a temp. between 1200 and 1400‹ C., e.g. 1350‹ C. The proportion of Si containing vapour in the reaction zone is preferably equal to or less than an equimolar proportion compared with the carbon containing vapour in the zone. The silicon containing vapour and the carbon containing vapour may be provided in the reaction zone by heating solid silicon and solid carbon in that zone in the presence of H 2  with a minor proportion of chlorine.
