In a machine or apparatus comprising twist heads imparting twist to travelling yarns passing therethrough and associated heaters for heat-setting the yarns in a twisted condition; each head is so formed that yarn entering it in one direction and in the course of being e.g. frictionally, twisted thereby can leave the head either in the same general direction or in a changed direction at an angle with respect to the first direction, as may be required: the heads are so arranged in relation to the heaters as to cause a yarn leaving a twist head and about to enter and pass through a heater to change direction whilst the twist in the yarn continues to accumulate. In the apparatus shown for producing a single fourfold twist (crimped) yarn TY (or, optionally single, two-fold or three-fold yarns) yarns Y1 and Y2 at one side of the apparatus or machine unit pass from supply packages 2 housed in a pivotally removable magazine, thence over an input capstan 9, downwards and through a twisting head THI from opposite ends thereof, vertically downwards and over or through a short e.g. 3 ft., heater, Fig. I (not shown) through head TH2, horizontally to and through head TH3, vertically upwards and over or through a long e.g. 6ft., heater through head TH4, horizontally to and through head TH5, over output capstan 11, upwardly and over another capstan 12, finally downwards together with yarns Y3, Y4, (which have followed similar paths on the other side of the apparatus) to wind-up at 13. The elongate, vertical heaters have heat retaining covers carrying yarn guides whereby yarns are held clear of heating tracks in the heater when the covers are open and closure of the covers moves the yarns into operative position in the tracks, Figs. 3 and 4 (not shown). The covers close automatically on starting the apparatus and open when the apparatus stops or in an emergency e.g. yarn breakage. Yarns may be guided to travel back in reverse directions through the same heaters along duplicate tracks.

Title: Extensible conveyors
IPC: B65G15/04
Filed: 1944-03-07
Abstract: 580,281. Endless-belt conveyers. INGHAM, E., and MINING ENGINEERING CO.; Ltd. March 7, 1944, No. 4234. [Class 78 (i)] In mining or like operations in which an endless belt conveyer extends behind a loading machine, the material is delivered from the loader to a carrying strand of the conveyer extending between a terminal drum attached to the loader and a fixed delivery point and the loop of the belt beyond the delivery point is carried around a slidable return drum which is drawn forward as the loader advances, predetermined belt tension being maintained by poweroperated means exerting a. pull on the return drum. In the embodiment shown, an extensible belt conveyer 9 is drawn along the coal face by a loading machine 1, the terminal drums 8 of the conveyer being attached to the loader. The coal is fed by a loading bar 4 co-operating with combs 5, on to a rotary disc 7 which delivers it to the lower run of the conveyer 9 from which it is discharged by a plough 10 to a gate conveyer 12. The belt is tensioned to a predetermined amount by a winch or warping pulley 15 driven by the conveyer driving motor 16 through a hydraulic clutch and connected to the return drum 14 by a rope 17 passing round pulleys 18. When the drum 14 has been advanced a predetermined amount, the loader and the conveyer are stopped to allow the belt to be broken and an additional piece of belting inserted. The drum is then returned by the winch 15 until the belt is again tensioned and the conveyer and loader started again. Coal from the face A may be filled on to the strand 9b of the conveyer and discharged by a plough 10a. Specifications 580,280 and 580,282 are referred to.

Abstract: Organosilicon compounds of the average general formula <FORM:0802467/III/1> in which each R is a monovalent hydrocarbon radical, R1 is an alkylene radical, each R11 is an alkylene radical containing at least 2 carbon atoms, n has a value of at least 1. R111 is hydrogen, a saturated hydrocarbon or acyl hydrocarbon radical and a has a value from 0 to 3 inclusive (see Group IV (a)), are used as anti-foaming agents.  The products of Examples (1) and (2) are good anti-foam agents for ethylene glycol anti-freeze solutions.ALSO:Organosilicon compounds of the average general formula <FORM:0802467/IV (a)/1> in which each R is a monovalent hydrocarbon radical, R1 is an alkylene radical, each R11 is an alkylene radical containing at least 2 carbon atoms, n has a value of at least 1, R111 is hydrogen, a saturated hydrocarbon radical or an aryl hydrocarbon radical, and a  has a value from 0 to 3 inclusive, may be made (i) by reacting an unsaturated ether of the general formula R111(OR11)nOB, in which B is an alkenyl radical, with an organosilane or siloxane containing an Si-H group, preferably in the presence of catalysts such as organic peroxides, platinum or chloroplatinic acid.  Where R111 is hydrogen it is preferable to block the OH group in the unsaturated ether with a triorganosiloxy group prior to reaction with the silane or siloxane; or (ii) by reacting a hydroxyalkyl silane or siloxane with an alkylene oxide at 70 DEG  to 150 DEG  C. in the presence of catalysts such as H2SO4, SnCl4 and AlCl3.  The R radicals specified are alkyl, cycloaliphatic, aryl, aralkyl or unsaturated aliphatic.  The novel siloxanes may be copolymerized with conventional siloxanes containing silicon-bonded hydrocarbon or halogenated hydrocarbon radicals.  In typical examples: (1) polyglycol A was reacted with trimethylchlorosilane and the resulting trimethylsiloxy-blocked product was then reacted with a trimethyl end-blocked methylhydrogensiloxane in the presence of chloroplatinic acid. The product was then hydrolysed to remove the trimethylsiloxy groups from the glycol side chain and purified to yield a water-soluble liquid of the formula <FORM:0802467/IV (a)/2> (5) the vinyl ether of ethylene glycol was reacted with tetramethyldisiloxane in toluene and in the presence of chloroplatinic acid to give the compound <FORM:0802467/IV (a)/3>  Uses.-The products are useful as emulsifying agents, e.g. for phenylmethylsiloxanes, anti-foaming agents, mould-release agents, lubricants and as cosmetic additives.

IPC: H01L35/08
Filed: 1964-02-03
Abstract: 1,064,947. Thermocouples. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 13, 1965 [Feb. 3, 1964], No. 4465/64. Heading H1K. Manufacture of a known kind of thermocouple (Fig. 1, not shown), consisting of two dissimilar semi-conductors (e.g. lead telluride and germanium telluride) joined by a metal (e.g. nickel) member to which they are alloyed, is complicated by the fact that the temperature at which one of the semi-conductors alloys with the metal is above the melting point of the other semi-conductor. To avoid this disadvantage the invention provides for the metal member to be replaced by a body consisting of the lower melting point semi-conductor alloyed with a noble metal which further depresses its melting point. In the case of a PbTe-GeTe couple the joining body would be of GeTe alloyed with 1 to 2% by weight of gold (or silver or platinum). Fig. 2 (not shown) depicts a preferred form of couple of this constitution and Figs. 3 and 4 (not shown) depicts a thermopile consisting of a series connected array of such couples. The exposed surfaces of the semi-conductor bodies used in the couples are insulant-coated.

Abstract: 1385333 EHT supplies MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 31 Jan 1972 [4 Feb 1971] 4523/72 Heading H2F In a TV receiver, power for a flyback transformer and EHT supply unit is obtained from a controlled power source 22 adjustable in dependence on EHT drift as detected by an auxiliary isolated winding 14 on the flyback transformer 11. As described, the A.C. mains is rectified at 23, smoothed at 24 ... 26 and passed by transistor 27 to the horizontal output and EHT circuit 12 ... 17. Variations in EHT voltage due to change in cathode-ray tube beam current, result in a voltage change in winding 14, which, after rectification at 18, is passed by transistors 29 and 28 to make appropriate change in the impedance of transistor 27. In Figs. 3 and 4 (not shown) a further control signal is derived from the cathode of the cathoderay tube or the emitter of the horizontal output transistor and used to provide automatic brightness control. In Fig. 5 (not shown) the horizontal output stage is supplied from a constant voltage whilst a separate EHT supply is fed from the controlled power source.

Title: Data processing
IPC: G01V1/28
Filed: 1964-02-04
Abstract: 1,056,481. Seismic prospecting. TEXAS INSTRUMENTS Inc. Feb. 4, 1964 [Feb. 15, 1963], No. 4686/64. Heading H4D. Seismic signals are processed on a velocity basic (i.e. the apparent velocity of seismic wave propagation in the direction of the array) in order to separate desired waves from undesired waves when both have velocities such that their frequency and wave number spectra overlap. The signals may be derived from a plurality of detectors (geophones) receiving energy from a single shot or from a single detector responsive to a plurality of spatiallyseparated shots. The Specification discusses the theory of operation of the proposed system the practical realization of which leads to an arrangement for indicating the presence, inside or outside a predetermined time delay range, of signals in each seismic trace having a time delay with respect to signals in another trace each trace being a function of its spatial origin in relation to the spatial origin of each other trace. In operation each trace is weighted in relation to each other as a function of their respective spatial origins and bi-directionally time shifted in relation to each other as functions of such origins and the predetermined time delay range and all the weighted and time shifted traces are then composited to produce the desired result. The manner in which this is effected is described in connection with the partschematic diagrams of Figs. 3 to 6 (not shown). Fig. 7 shows a functional diagram of the arrangement comprising a magnetic drum record 1 of the field traces the signals recorded on each track being fed to a magnetic drum 2 the recording and play-back heads of which are adjusted so that each trace is time-shifted as a function of its spatial origin (i.e. the position of the associated geophone in the spread) and of the desired centre velocity (termed " tilting ") each trace so operated on being subjected to a further time shifting operation involving a progressive time advance and a progressive time retardation (so that two traces are produced for each input trace) termed " slicing" by means of a magnetic drum 4 with suitably positioned recording and play-back heads. (In practice the functions performed by drums 2 and 4 are performed by a single drum with appropriately positioned heads.) The signals read-off drum 4 are then suitably weighted by means of resistors 3 and after summation in 8 fed to a recording drum 20, operated synchronously with drum 1, on which the corrected traces are produced. The practical operation of the equipment is discussed and an application to the processing of data obtained in underwater seismic operations is described.

A transistor switching circuit operated from a supply having a voltage greater than the maximum safe value for the transistor is protected from damage by connecting a 4-layer diode 2 in series with the transistor and shunting the transistor by a resistor 6 such that the current flow is less than the diode breakdown current, whereby the voltage drop across the diode reduces the transistor voltage to a safe value. When the transistor is rendered conductive the diode breaks down and the full voltage is applied to the relay or other load 3.
Patent GB-430107-A (GB)
Title: Improvements in or relating to the manufacture of rubber thread
IPC: B29D99/00
Filed: 1934-02-13
Abstract: A process for making rubber thread wherein an aqueous rubber dispersion is deposited on a continuously progressing surface having a series of grooves therein in the direction of travel of the surface and caused to solidify in the grooves is characterized in that the dispersion is a heat-sensitized dispersion, such as those employed in Specifications 284,608, 292,964, 330,520, and 335,621, [all in Class 70].  To cause the dispersion to set the surface may be heated or the deposit in the grooves passed through a heated atmosphere.  In an example, the process is expedited by surrounding the lower half of a grooved, rotating, heated cylinder carrying the setting dispersion by a casing containing hot air. The threads may be stretched to 6 or 7 times their initial length by being fed, after stripping, on to a conveyer running at a higher speed than the stripping roller. Stiffness due to stretching may be removed by heating in water or other medium before or after drying, or before or during vulcanization.  By coating the grooves with anti-wetting medium, e.g. oil or talc, the deposit may be caused to set with a convex upper surface; thus a groove of semicircular cross-section may produce a practically circular thread.  Specification 410,415 also is referred to.
