Abstract: 1293825 Neckties A G WYNES 13 Aug 1971 [1Sept 1970] 41880/70 Heading A3V A necktie comprises a length of material folded around an insert with the folded areas being bonded or sealed to each other and the insert by an adhesive or heat sealable plastics layer applied to the length of material. The material may be plastics film or woven or non- woven fabric or laminated paper coated with a heat sealable plastics layer. The tie is made by placing a rigid core on top of the length of material, with the insert on top of the core, folding the material around the insert and sealing the material together and to the insert, withdrawing the core and sealing the ends of the tie. A method of printing and cutting the material is also described.

Title: Multi-stove blast furnace installation with staggered operation of stoves
IPC: C21B9/00
Filed: 1962-11-06
Abstract: <PICT:0987294/C6-C7/1> <PICT:0987294/C6-C7/2> <PICT:0987294/C6-C7/3> <PICT:0987294/C6-C7/4> In a blast-furnace installation the hot-blast stoves are connected in parallel and are sequentially placed on blast, a fresh stove being introduced while the preceding one is still on blast, the temperature of the resulting air stream being maintained at a predetermined temperature by varying the proportion of air passing through the two stoves.  In a preferred embodiment the control valve of one stove is maintained in the fully open position, control being effected solely by adjustment of the valve of the other stove.  As illustrated in Fig. 1, stove I is equipped with main control valves CBV-I and HBV-I and proportioning valve PV-I, stoves II, III, IV being identical in all respects.  Temperature sensing device 10 transmits a signal to comparator SC wherein it is compared with a set point signal representing the desired blast temperature. The temperature of the blast from the various stoves, and their sequence of operation are shown in Figs. 2 and 3 respectively.  At any time valve PV of one of the stoves on blast is maintained fully open, blast temperature being controlled by adjustment of valve PV of the other stove on blast, e.g. from "a" to "a1" PV-II is adjusted, and from "a1" to "b" PV-I is adjusted.  Suitable circuitry for bringing about the appropriate sequential operation of the control is described (see Division G3).  In the modification of Fig. 6 some cold air may by-pass the stoves and pass direct to the mixer under control of thermosensitive device 14 to provide fine control of the blast temperature.  Specifications 883,508, 940,653 and 940,654 are referred to.

Abstract: 1362211 Knitting-machines G BILLI & C SpA 9 Sept 1971 [14 Sept 1970] 42015/71 Heading D1C In a circular machine alternate stitch cams e.g. 17 are set so that previously drawn loops M, fail to knock-over, and a selection is made so that some only of the needles, 37, take yarn at the next feed. Prior to cam 17 all the needles are raised to clear by part 47B of bolt cam 47. Loops M 3  are drawn by stitch cam 17 set at a higher level than interveening cams 15, 19. The previously drawn loops M, are not knocked-over. Selected e.g. alternate needles 3z continue in track T 3  to knock-over at the next stitch cam 19. The remaining needles are raised in track T 1 , but do not clear loop M 3 . The new yarn F 5  is taken and loops M 3  and M 5  knocked-over at cam 19. Loops M 1 , M 3  associated with needles 3z are retained in a two-throated sinker. Needles can be raised to a higher level by cam 47 to take a reinforcing yarn.

Abstract: 1304223 Testing apparatus for motor vehicles AUTOSCAN Inc 8 Sept 1970 [10 Sept 1969] 43017/70 Headings G1N and G1W Apparatus for producing a load on a motor vehicle which simulates different road conditions comprises means for measuring electrically the velocity of the vehicle wheel and modifying the signal in accordance with a predetermined relationship between velocity, acceleration, road slope and load to produce an electrical output which is converted to a pressure exerting a corresponding braking force on the wheel. The engine driven wheel rests on a roller 35, Fig. 1 whose speed is measured by a tachometer 45. The speed signal is fed on lead 52 to a road  condition simulator 13, where it is integrated at 49, Fig.3 to measure distance, and differentiated at 63 to measure acceleration. The distance signal after each half-mile causes a pulse generator 51 to operate a stepping switch 47 which selectively energizes relays R1-4 whereby the velocity and acceleration signals are combined in a predetermined manner consistent with different road conditions to simulate the different load conditions on the vehicle, and produce a control signal on lead 14 which is amplified at 15 and determines the pressure from a piston 27 on a disc brake 29 attached to the roller 35. The torque applied to the roller and wheel is measured by a strain gauge cell 41 to give a feedback signal to amplifier 15. The simulator 13 includes resistors selected by switch 53 to represent the effects of wind load, the weight of the vehicle and the slope of the road.

Abstract: A method for burning a petroleum oil which has a viscosity above 40 S.S.F. at 122 DEG  F. comprises operations to form an oil-in-water emulsion of the oil, to have a viscosity of less than 150 S.S.F. at 77 DEG  F. and wherein 60% by volume of the emulsion is a disperse phase of oil droplets, and to invert the oil-in-water emulsion immediately prior to combustion to form a water-in-oil emulsion which is intimately mixed with air before passing into the combustion zone. An emulsifying agent is added either to the oil and water separately before mixing or to the oil-in-water mixture.  The agent may be a sodium salt of a fatty acid having 12 to 24 carbon atoms per molecule.  The emulsion is inverted by agitation, either by increased speed and pressure of a fuel pump or by Pohlman-whistle (ultrasonic resonance device) with which a pre-heater may be used for vaporization of some of the water.  The water-in-oil emulsion is then atomized by the air. The oil may have a viscosity from 40 to 300 S.S.F. at 122 DEG  F. and the oil-in-water emulsion may have a viscosity below 90 S.S.F. at 77 DEG  F.

Title: Crimped staple fibres
Inventor: MURLEY JOHN REGINALD
IPC: D02G1/12
Filed: 1961-12-05
Abstract: Staple fibres which may already have a sinusoidal or sawtooth crimp are crimped (or additionally crimped) to produce random, non-uniform, multiplanar crimps or deformations therein by compressing e.g. in a baling press, a single or composite bale of randomly arranged fibres e.g. separated and opened cut tow, to a density which is at least 50% of the density of a single fibre in the bale.  The pressure is maintained for a time e.g. 15-60 seconds, sufficient for deformation of the fibres in their longitudinal direction beyond the elastic limit, and also of their cross-section, involving a plastic deformation.  When the pressure is removed, the fibres retain three-dimensional crimps &c. (at least twenty deformations per linear cm.) without any fusion between fibres.  The fibres are of a synthetic polymer e.g. polyacrylonitrile, polyamide, polyester such as polyethylene terephthalate, polypropylene, vinyl and polyoxymethylene polymer.
