Title: Manufacture of patterned cellulose triacetate fabrics
IPC: D06Q1/02
Filed: 1957-12-23
Abstract: A fabric having a substantially smooth surface and a patterned tone-on-tone effect is made by embossing with a heated surface a fabric comprising fibres of cellulose triacetate but not comprising other thermoplastic fibres, dyeing the embossed fabric and then subjecting the dyed fabric to heat treatment to increase the crystallinity of the cellulose triacetate and ensure complete elimination of the embossed texture.  In a preferred method, the fabric before embossing comprises fibres of cellulose triacetate having a normal degree of crystallinity, and after dyeing is given a heat treatment which increases the degree of crystallinity sufficiently to give the fabric a sticking temperature of at least 220 DEG C.  Embossing may be effected at about 200 DEG -220 DEG C., and dyeing by means of a hot aqueous dyebath, which may contain an aqueous dispersion of a substantially water-insoluble dyestuff and a wetting agent.  A suitable finish may be applied to the fabric after dyeing but before the heat treatment, e.g. a mixture comprising an aqueous dispersion of a silicone and colloidal silica. Specifications 758,442, 791,391, 791,392 and 828,822 are referred to. Reference has been directed by the Comptroller to Specification 812,697.

Title: Improved binder composition
Inventor: SHANNON RICHARD FREDERICK
IPC: D04H1/64
Filed: 1965-09-20
Abstract: A phenolic resin composition comprises 97 to 60% by weight of a novolac resin, 3 to 40% by weight of a resole resin and hexamethylene-tetramine in an amount by weight less than that of the novolac resin, suitably 8 to 16% by weight of the novolac resin.  The hexamethylene-tetramine acts as curing agent for the composition which cures on heating.  If the composition is to be used as a binder, e.g. for mineral fibres or as a moulding composition it may be prepared in an alcohol or aqueous solution. Alternatively, the composition may be foamed by adding thereto a solid blowing agent which decomposes on heating during the curing step.ALSO:Mineral fibres may be bound together by a phenolic resin composition comprising 97 to 60% by weight of a norolec resin, 3 to 40% of a resole resin and hexamethylene-tetramine present in an amount by weight less than that of the norolec resin.  The composition may be used in the form of a powder or in an aqueous or solvent solution system.  Glass fibres are suitable fibres for treatment with the phenolic resin composition which is cured by heating.  The composition may also contain a blowing agent in which case the resulting fibrous product is bound by a foamed binder.

Title: Improvements in or relating to automatic control systems, for electrostatic precipitators
Inventor: DARBY KENNETH
IPC: B03C3/68
Filed: 1957-12-30
Abstract: 859,784. Automatic control systems for electrostatic precipitators. LODGE-COTTRELL Ltd. Feb. 24, 1959 [Dec. 30, 1957], No. 40330/57. Class 38 (4). In an electrostatic precipitator the average discharge electrode voltage, defined as the average voltage applied to the electrodes over a fairly long time interval, of up to several seconds, is maintained at a maximum value by means responsive to the rate of change of the electrode voltage. A variable ratio transformer VR, Fig. 2, supplies a high-tension transformer TR the output of which is applied via a rotary rectifier to a precipitator P. A voltage proportional to the electrode voltage is derived from a tapping B of a potential divider and after amplification by a high-gain pentode PV, Fig. 3, applied through a capacitor C4 to a power winding of a magnetic amplifier. A process-timer PT sequentially closes a " raise " contact PR, causing a regulator motor RM to move the slider of the transformer VR, and then after a short period opens the ' raise " contact and closes a " lower contact PL applying a voltage to the regulating motor dependent on the reactance of a transductor SR. The rectified control output of the magnetic amplifier is applied to a winding DC1 to vary the reactance of the transductor in dependence on the rate of change of the electrode voltage during the " raise period so as to tend to maintain the average electrode voltage at a maximum value. When the magnetic amplifier is arranged to respond to an increase in average electrode voltage, a winding DC2 is energized to set up a magnetizing flux opposing that of the winding DC1. In a modification, the valve amplifier is not used and the magnetic amplifier has two power windings with differing time constants directly connected to tapping B. In a further modification, the magnetic amplifier is arranged so that the output control current depends on the direction of change of the precipitator voltage. The output from a current transformer CT through a thermal relay S2 actuates a relay EM to drive the regulator motor in the "lower" direction when the primary current of the H.T. transformer exceeds a predetermined value. Specification 832,342 is referred to.

Abstract: 1,056,775. Joint-making packing; washers; locking nuts and bolts. PARKER-HANNIFIN CORPORATION. Oct. 7, 1964 [Oct. 23, 1963], No. 40896/64. Headings F2B and F2H. A sealing gasket comprises a ring of resilient material defining a cylindrical surface having one or more projections which extend over only a part of the circumference. -The projections have an axial thickness at the crest less than that at the base, they have a peripheral length of base greater than the axial thickness of the base and they have an axial thickness of base less than the axial length of the cylindrical surface. As shown in Fig. 2, the body 17 of rubber or synthetic rubber or resin is provided with three internal projections 26 and is surrounded by a metal or hard plastic ring 16. In assembling; the projections flex to allow the gasket to be pushed down over the threads 28 of a bolt or fitting and when compressed by a nut 58, Fig. 5, the body of the gasket is caused to deform and seal the crest of the thread for more than one turn so as to prevent axial leakage of fluid. and the projections are caused to deform and seal against the flanks and root of the thread to prevent spiral leakage. The projections may be formed on the body in an inclined position so as to correspond with the helix angle of the thread. If desired, a washer may be interposed between the nut and gasket to absorb turning friction of the nut. The ring 16 surrounding the body 17 may be of the same material as the body and formed integral therewith; in other arrangements, the ring 16 may be provided with locking prongs or reinforced by metal washers when made of the same material as the body. In further embodiments, the gasket may be provided loosely within, or bonded to, a rabbet of a nut or, as shown in Fig. 12, bonded to a groove 95 of a nut; in the latter case, the inner diameter 90 of the body must be initially smaller than the crest diameter of the thread since there is no axial compression. Fig. 14 shows three projections 107 extending radially outwardly from the body portion 102 which may be either bonded to a groove in a bolt or incorporated in a rabbet at the end of a bolt.
