Abstract: 1,105,341. Crimping yarn. COURTAULDS Ltd. 4 Jan., 1965 [9 Oct.. 1963], No. 39756/63. Headings D1D and D1F. A process for the production of crimped, bulked yarn comprises passing a plurality of plasticised continuous filaments into a zone of turbulent fluid which imparts a false-twist to the filaments, and subsequently passing the fluid carrying the filaments through a constriction, thereby intermingling the crimped filaments. As shown the apparatus includes a yarn inlet 2, a fluidfor example air or waterinlet 11, and a flexible, transparent tube 12 having an adjustable clamping device 14 to form the constriction. The filaments may be of cellulose acetate, diacetate, or triacetate, or polyamide, polyethylene, polypropylene, polyacrylonitrile, polyester, or viscose rayon, or they may be composite filaments, for example, bicomponent filaments. They may be plasticised by heat, preferably by raising their temperature above the second order transition point, by means of steam, by contact with a heated roller, or by infra-red heating. Alternatively the filaments may be treated with a swelling agent which may be the residual spinning solvent, for example methylene chloride in the case of cellulose triacetate filaments.

Title: Electric arc working method and apparatus
IPC: B23K9/09
Filed: 1967-08-31
Abstract: 1,200,643. Welding by fusion. UNION CARBIDE CORP. 31 Aug., 1967 [2 Sept., 1966], No. 39785/67. Heading B3R. [Also in Division H2] An arc-welding supply system comprises a transformer-rectifier arrangement 1, 7, providing a single phase, half-wave rectified output fed to a wave-shaping circuit comprising members L, C, R of which L and/or R can be adjusted and the value of C chosen to produce a desired waveform 2, 4, 6 or 8, which has the same frequency as the A.C. supply and which corresponds to the requirements of the welding operation, e.g. high or low current spray transfer or short-circuiting metal transfer. Typical values of transformer output voltage and L, C, R are given for a MIG welding operation using argon shielding gas and a consumable aluminium electrode, the various operating conditions, e.g. feed speed, arc length, wire diameter, also being specified. It is stated that a particular application of the supply system occurs when the average value of the ourrent supplied to the arc is correlated with the consumable electrode feed speed such that for each wave of the waveform, a length of consumable electrode is consumed equivalent in volume to a drop of molten metal whose diameter lies in the range <SP>2</SP>/ 3  to <SP>1</SP>/ 3  of the wire diameter. Such correlation may be achieved by adjusting the transformer output voltage and/or the values of L and/or R. A " hot start " may be achieved by short-circuiting the resistor R, this latter condition also being used for certain welding operations. The electrode may be non-consumable. The rectifier 7 may be a siliconcontrolled rectifier or a silicon diode. In another example using a thoriated tungsten electrode and argon shielding gas, an additional resistor is connected in series with the inductance L to limit short-circuit current when starting. The transformer 1 may be replaced by a motordriven alternator whose commutation provides the rectifying action. A comparison is made between the continuous waveforms 2, 4, 6, 8 and the prior art superimposed-pulse waveform having discontinuites at the current decay points 13.

Filed: 1971-08-20
Abstract: 1362198 Train control BRUSH ELECTRICAL ENG CO Ltd 20 Aug 1971 [21 Aug 1970] 40325/70 Heading B7N In a train control arrangement a communication system links all the driven vehicles of the train whereby any one of the driven vehicles designated the master vehicle can control at least the direction of movement of the other vehicles designated slaves. Each driven vehicle has a drive control cab at each end and as described the vehicles are linked by a cable pair fed with time-division multiplex signals comprising successive groups of equal numbers of binary coded pulse signals. In each signal group two pulse positions are associated with the end cabs of the master vehicle so that the end nearer the slave or slaves can be signalled and two positions with the required direction of motion set by the master driver. With this information and an indication of its can end nearer the master, at which the information was received, the direction of movement for the slave can be unambiguously determined. A number of pulse positions, e.g. 4 carry a repeated fixed signal which can be checked for quality of information on each slave vehicle. If the fixed signal is not correctly received during three successive pulse groups a control action such as cut-off of traction supply or braking is initiated. A number of the pulse positions can be used for transmitting fault information from the slave vehicles to the master. The time division multiplex transmitter and receivers and the synchronizing system are described.

Abstract: A method for improving the adherence of a layer of granular material provided on a support comprises treating the support and the granular layer while in the moist state with dry vapour of at least one hydrolysable silicon compound and subsequently drying to form dry SiO2.  The hydrolysable silicon compounds preferably have a boiling point below 170 DEG  C. and may be tetramethyl silicate, tetraethyl silicate, SiCl4 and SiHCl3.  The method may be applied in making the luminescent screens of cathoderay tubes or luminescent layers on the inside surfaces of envelopes enclosing high-pressure mercury vapour discharge tubes.  The water content of the layer of granular material may be adjusted prior to the above treatment.ALSO:A method for improving the adherence of a layer of granular material provided on a support, for example, in a cathode ray tube or a high-pressure mercury discharge tube, comprises treating the support and granular layer whilst in the moist state p  with the dry vapour of one or more hydrolysable silicon compounds and subsequently drying to form silica.

The example describes improving the adherence of luminescent material on the screen of a cathode ray tube.  Such cathode ray tube screens may be further coated with a thin layer of metal permeable to electrons on the surface nearer the electron gun.

As described, a concrete slab is cast about prestressed wires on the stress- and setting-bed 10 (described in Specification 798,964) and when hardened, plates covering recessed rollers 12 are retracted so that the rollers 12 rise and move the slab on to support rollers 18. Opposing drive rollers 28, 30 having a rubber surface and rubber discs respectively, feed the slab 13<SP>1</SP> back over rollers 20 until a saw 24 can cut off a desired length to form a beam 13<SP>11</SP>. A ram (44) (see Fig. 2, not reproduced) moves to push the cut beam 13<SP>11</SP> off the rollers 20 to a fork lifttruck, the ram movement serving to raise orthogonally arranged rollers 22. The remainder of the slab 13<SP>1</SP> is then cut into further beams 13<SP>11</SP>. A slab 13 that has meanwhile been cast and hardened on bed 10, is moved on to rollers 18 for similar cutting. Drive rollers 28, 30 are supported in trunnions (36), (38) (see Figs. 3, 4, not reproduced) for vertical movement on guides (40); the rollers are pulled together by hydraulic actuators (42) and can move apart to accommodate slab curvature. Roller 28 is driven.

Abstract: 863,882. Electric resistors. INTERNATIONAL RESISTANCE CO. Dec. 19,1958, No. 41079/58. Drawings to Specification. Class 37. A resistor comprises the combination of a core of insulating material coated with a layer of nickel-chromium alloy having a low-temperature coefficient of resistance and another layer of chromium. As described, a resistor is made by depositing a film of an alloy of nickel, chromium, aluminium and copper on to a ceramic core by a vacuum deposition, and then similarly depositing a film of chromium on top of the first film to improve the stability. Terminal leads are then attached, such as by metal caps, and if required the completed resistor may be given a protected covering such as a tube of insulating material or a moulded plastic jacket. In the example described, the amount of nickelchromium alloy condensed has a resistance per unit area of 80-90% of the desired final value of the film. Specification 863,881 is referred to.
