Abstract: 1396885 Moulding foam sections A D BLAKE 17 May 1972 [17 May 1971] 15207/71 Heading B5A A process for the manufacture of shaped sections of foam plastics material comprises feeding a foamable material between two belts 5 and 7 which are moved over a moulding surface 1 by means of rollers 10 and 11; the moulding surface has an initially flat portion 2, a tapered transition portion 3 and a final channel shaped portion 4 so that the foam is gradually transformed from an initial sheet form to a final cross-section, at which latter stage the foam has gelled and cured. The belt 7 may be a reinforcing fabric and the belt 5, which acts as a covering layer, may be removed after moulding. Foam material which may be used include polyurethane, polyester, silicone, urea or phenol formaldehyde foams, and may comprise fillers such as stone, flints, glass fibres. Depending on the intended final use of the article, the surface of the foam may be treated to render it, for example, impermeable or non-inflammable. Surfacing layers of metal foils, plastics sheets, plywood, "Formica" (R.T.M.) may be applied to the surface of the foam before it has completely gelled. The articles produced are suitable for use as ductwork and trunking for the transport of hot and/or cold air.

Abstract: 152,715. Haddan, A. J. H., (Textile Utilities Corporation). June 17, 1919. Knitting, methods of.-Relates to a method whereby fabrics having the appearance and character of woven fabrics, with or without a nap or pile and with a minimum tendency to stretch can be expeditiously produced. The body fabric is filled substantially solid with weft-wise extending ribs and comprises tightly-knit warp chains the loops a" of which interknit with and tightly bind groups or bundles of weftwise extending threads c<1> which are laid in regular sinuous form throughout the fabric preferably across eight needles. Successive weft threads have their turns or bends arranged in progressively advanced position, weft-wise of the fabric, and tightly interknit with the loops of successive courses of the warps at the turning-points. The threads a<1>, c<1> are under relatively heavy tension which may be provided by suitably weighted brake straps acting on the beam from which the threads are taken. If a pile fabric is desired, pile threads b<1> are laid in under relatively light tension and are pulled by the action of knitting into relatively deep loose free loops b<11>. The machine described in Specification 140,994 may be employed. The threads b<1>, c<1> are laid in position to be engaged by the backs of the needles by shitting guides b, c. The needles then rise and traverse the guides in the order c, b, a. The guides a are then shifted through a sufficient distance to lay each warp a' across one needle. The needles are then traversed across the guides and sunk to cast off the loops a<11> and tie in the threads b<1>, c<1>. Instead of forming foundation warp chains the warps a<1> may be knit to form a net or fabric.

Abstract: 1,267,942. Continuous casting. ROBLIN INDUSTRIES Inc. 25 March, 1969 [18 July, 1968], No. 15520/69. Heading B3F. [Also in Divisions C7 and F4] To reduce the amount of oxide inclusions greater than 20 microns in size in a continuously cast strand, the steel to be cast is teemed from a ladle 10 to maintain, possibly by automatic control, a constant head in a tundish 16 and the melt passing from there to at least one reciprocated mould 22 or 24 is protected in an atmosphere of argon which is continuously changed to deoxidize the stream. O 2  in solution in the steel is said to be removed, oxides reduced and CO formed and removed. The argon is fed from holes 72, Fig. 2, in a cross-piece 66 at the end of a tube 62, into a space 74 enclosed by a porous woven sleeve 45 of asbestos surrounding each melt stream 76. It bleeds out of the space at 23 c.ft.(min., when casting two 4-inch square billets, to give a rate of about 48 c.ft./ton of steel. The sleeve 45 is clipped to flanged end collars 36, 38 which are pressed apart by a spring 42 to seal against a mould top and a slide valve assembly 32 on the tundish. 16. A graphite insert 60 prevents welding of the slide-plate 54. Two baffles 80, 82 across the tundish facilitate separation of inclusions to form slag at the surface of the melt in the tundish. Ca and/or Si are used as deoxidants in the ladle to obtain an oxygen content in the solidifying steel of 40-90 parts per million.

Abstract: 1348525 Frequency meters; monostable transistor circuits ITT INDUSTRIES Inc 20 May 1971 [23 May 1970] 15932/71 Headings H3A and H3T A circuit for indicating the speed of rotation of an engine by measuring the frequency of ignition pulses consists of a monostable circuit comprising: a normally blocked transistor T1; a normally conducting transistor T2; a timing capacitor C; a first circuit for charging the capacitor C at the termination of the unstable state over a charging period which is short compared with the unstable period; and a second circuit for charging the capacitor in the other direction during the unstable state, the duration of the unstable state being less than 70% of the time constant of the second circuit. In the stable state, T1 is off, T2 is on, and the current path UB, D3, R1, base-emitter path T3, collector-emitter path T10, earth causes capacitor C to charge with its left-hand plate positive with respect to its right-hand plate. Application of an ignition pulse at E turns on transistor T7 to render diodes D1, D2 conductive and turn off T3. The emitter of T3 then falls, the fall being transferred via capacitor C to cut off transistor T2. The consequential rise in the collector potential of T2 is fed via T4 to turn on T1. Capacitor C now charges from UB in the reverse direction through resistor R, diode D2 and transistor T1 until the potential on its right-hand plate rises sufficiently to turn T2 on again. When this occurs the cross-coupling with T2 ensures rapid switching back to the stable state with T1 off and T2 saturated. The arrangement of diodes D1, D2 ensures that the circuit is insensitive to noise pulses from the power supply. The resulting constant width output pulses are fed to a meter A to produce an indication proportional to frequency, and hence engine speed. Components T8, T9, D4, T10 may be omitted, Fig. 1 (not shown).
