Title: Method of and apparatus for drying "crepe" and other fabrics of paper, hair, wool or other material
IPC: D06C7/00
Filed: 1935-08-30
Abstract: 460,306. Drying fabrics. RIDGWAY, W., HANNAY, R. J., and BERRY, D. S. Aug. 30, 1935, No. 24211. [Class 34 (i)] In a method of drying fabrics, including crÛpe fabrics and fabrics of paper, hair, or wool, the fabric is delivered to a drying-apparatus at a speed which is greater than the speed of conveyers receiving the fabric within the apparatus, so that the fabric assumes a wavy or sinuous form and passes from one conveyer to another in such a manner as to permit of a fresh disposition of the waves, shrinkage of the fabric while drying taking place without tension. In the construction shown, the drying chamber is divided into four sections, each provided with endless conveyers. The fabric f to be dried is fed through rollers f<1> and delivered on to the conveyer a, passing eventually over all the conveyers in the first section 1. It then is guided on to the conveyer c in the second section 2 and is passed in similar manner over all the conveyers in that section and in the remaining sections, being finally withdrawn from the drying apparatus by rollers g. The speed of feed of the fabric is greater than that of the conveyer so that the fabric is carried forward in sinuous form, as shown. The conveyers are of lattice form and are provided underneath the upper stretch with heating coils b. Over each conveyer is a duct d through which hot air is passed, the air being extracted through ducts e. The ducts d, e are connected by trunks leading to a fan h associated with a heater i, so that the air from the drying chamber is re-heated and re-circulated. Some of the air escapes to atmosphere through outlets j, and fresh air is admitted through an inlet with control valve i <1>.

Abstract: 1,149,861. Moulding pipes. CESKOSLOVENSKA AKADEMIE VED. 31 May, 1966 [2 June, 1965], No. 24237/66. Heading B5A. [Also in Division F2] The method of making a chemically-resistant pipe lining includes providing a resin-mortar of a particulate reinforcing material, e.g. quartz sand or a mixture of quartz sand and ground asbestos, and a thermosetting resin, such as an epoxide resin, and forming the resinmortar in a tubular shape by internal and external forming means, and then hardening the resin-m ortar. A catalyst and an accelerator may be added to the resin-mortar. A vertical mould may be filled with a resin-mortar by means of a distributing bell under constant vibration by surface vibrators placed on the inner and outer members of the mould; the lining may be formed directly in a concrete or metal pipe used as an outer mould and by centrifugal rolling of the resin-mortar whereby the latter is compacted by a heated roller or heated mould which is rotated about a horizontal axis.

Title: Improvements relating to electric lamps suitable for motor cars
IPC: H01K9/08
Filed: 1923-10-01
Abstract: 226,882. McCulloch, G. Oct. 1, 1923. Filaments; reflectors and screens within bulbs. -An electric lamp comprises a pair of filaments, located on or in close proximity to an axis of a spherical bulb with one filament lying on one side of the centre of the bulb and the other filament on the other side of said centre, and two screens, one adapted to prevent the rays from one filament from falling on one half of the bulb while the other screen is adapted to prevent rays from the second filament from falling on the other half of the bulb. The two filaments may be combined in one long filament, the parts of which on either side of the centre of the spherical bulb are screened as above described. To prevent upward or dazzling rays when used in a motor-car headlight, the centre of the bulb is arranged to coincide with the focal point of the reflector 2, Fig. 1, the screen 6<a> prevents rays from the forward filament 5<a> from falling on the lower part of the reflector, while the screen 6 prevents rays from the rear filament 5 from falling on the upper part of the reflector. The screens mav have the shape of boat-shaped troughs, which may overlap, as shown in Fig. 2, and the outer end of one or both screens may be blocked by an end-piece 7. The inner surfaces of the screens are preferably reflecting surfaces. Modified arrangements of filaments and screens are shown in Figs. 6 and 7. The filaments may be connected in series or in parallel, and by the use of a switch either filament may be lighted independently of the other. To keep down the temperature of the screens and lead away or " earth " any " ionization " currents, a wire may be attached to them and taken through the socket of the lamp.

Title: Highly stable anaerobic compositions

Abstract: 1347068 Anaerobic curing compositions LOCTITE CORP 19 April 1971 [18 March 1970 4 Feb 1971] 24498/71 Heading C3P Anaerobic curing compositions comprise a polymerizable ester of acrylic acid or of an α- substituted acrylic acid (e.g. methacrylic or chloroacrylic acid), a peroxy polymerization initiator therefor, and dissolved therein a metal chelator having ligand atoms (e.g. N, O, S, Cl, Br, I, P, As and Se) other than an N atom which is part of a group. The metal chelator increases the stability of the composition and enables more active polymerization accelerators to be included therein. Preferred ester monomers are those containing at least two acrylic ester groups in the molecule or mono-acrylic esters containing a polar group. Hydroperoxides, in particular organic hydroperoxides, are preferred initiators, and also suitable are peroxides such as cyclohexyl hydroxycyclohexyl peroxide and t-butyl perbenzoate which form hydroperoxides in situ. Useful metal chelators include compounds such as tetrasodium ethylenediamine tetraacetic acid, o-aminophenol, salicylaldehyde, the disodium salt of o-thiobenzoic acid, the disodium salt of pyrocatechol, disodium oxalate, sodium diethyldithiocarbonate, malonic acid, acetylacetone and 8-hydroxy-1,2,3,4-tetrahydroquinoline. The compositions may also contain a polymerization accelerator, e.g. an amine, an organic sulphimide, succinimide, phthalimide or formamide. Other optional components include polymerization inhibitors, thickeners, plasticizers, dyes, adhesive agents and thixotropic agents; polyethylene powder is used in one of the examples.

Abstract: 1,144,067. Separating xylene isomers. JAPAN GAS-CHEMICAL CO. Inc. 2 June, 1966 [3 June, 1965 (2)], No. 24693/66. Heading C5E. m-Xylene is continuously extracted from a mixture of xylene isomers (including ethylbenzene) by charging the xylene mixture together with a diluent (e.g. hexane or CCl 4 ), liquid HF, and BF 3  (and optionally reflux mxylene) to an extractor operating under selected operating conditions which are defined in detail in terms of ratios between various components of the total charge, the m-xylene passing as a complex into the HF phase, from which it may be recovered by stripping and fractionation. Part of the crude or pure mxylene may be used as the reflux to the extractor. The remaining mixture of xylene isomers may be further treated to separate by fractionation an ethylbenzene fraction, and a mixed fraction of o- and p-xylenes, which can then be further fractionated to separate the two isomers. The p-xylene may be further purified by crystallization. Part or all of the m and/or o-xylene products may be isomerized to form an equilibrium mixture of xylene isomers which is returned for further extraction.

According to a first high temperature calcining method, the kiln is fired by burner 12 fed with oxygen or oxygen-enriched air through line 13, and the kiln 4 by burner 8 fed with preheated combustion air, which may be oxygen enriched, from cooler 6 via line 9, the waste gases from the two kilns passing independently into preheater 1. Partially calcined material may be extracted from stationary head 14. In other lower temperature methods, either burner 12 and oxygen supply line 13 may be shut off and valves (not shown) in the lines 9 and 16 closed, so that combustion air from cooler 6 passes through kiln 5 which now acts as an afterburner, on its way to calcining kiln 4, or burner 8 is turned off with the valves in the lines 9 and 16 closed so that waste gases from kiln 5 pass through kiln 4 on their way to preheater 1. In a modification (Fig. 3, not shown) three such rotary kilns are provided to give greater operational flexibility. The materials to be calcined may include magnesite, dolomite, limestone or other carbonates, oxides or hydroxides.
