A process for mixing together different types of fibres comprises passing several layers 1-7, each of one of the types of fibres to be mixed, to a spiked apron N for carrying away fibre from all the layers in a substantially vertical direction, and then during the time in which the lengths of all the layers are reduced by L/S where L is the maximum length of layer 1 and S is the number of layers, adding further fibre to each layer of the required type for that layer in succession to lengthen all the layers by L/S. Fibres either slide down the whole shoot formed by flaps K 1 -K 6  to the bottom layer, or through an open flap to the end of the layer directly beneath it.

Title: Improvements in the production of the dizinc salt of hydroxymethane sulphinic acid
Filed: 1951-11-08
Abstract: In a process for the production of the dizinc salt of hydroxymethane sulphinic acid the sodium salt of hydroxymethane sulphinic acid in aqueous solution is reacted with the equivalent amount of a zinc salt and the dizinc salt of hydroxymethane sulphinic acid is precipitated by bases while the temperature is kept low by cooling.  An inorganic base, e.g. an alkali metal hydroxide and an inorganic zinc salt are preferred, and the addition of the base is carried out slowly and with vigorous stirring to avoid precipitation of zinc hydroxide.  The process is of special importance when the sodium salt of hydroxymethane sulphinic acid is obtained by the catalytic reduction of sodium formaldehyde bisulphite or by the reaction of sodium hyposulphite, which can be obtained by electrolytic methods with the aid of sodium amalgam from bisulphites, with formaldehyde and sodium hydroxide.  In the example zinc chloride is added to an aqueous solution of the sodium salt of hydroxymethane sulphinic acid and the solution is stirred vigorously while aqueous sodium hydroxide solution is slowly added and cooling is applied.  The dizinc salt of hydroxymethane sulphinic acid is filtered off and washed with water and alcohol.

Abstract: 1,090,650. Gas turbine engine combustion equipment. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept.2, 1965 [June 26, 1964], No.26478/64. Heading F1L. The invention relates to combustion equipment for gas turbine engines of the kind comprising a series of flame tubes spaced angularly about the centre line of the engine. Each flame tube is mounted at its upstream end on supporting structure of the engine with provision for sliding movement longitudinally of the flame tube and for limited pivotal movement of the flame tube about its upstream end. The downstream end of the flame tube is connected for relative movement to a discharge duct through which the combustion gases are directed to the turbine. The discharge duct is arranged to be supported at its downstream end by a fastening element which permits movement of the discharge duct only in a direction substantially radially with respect to the engine centre line. The flame tube 10 shown is mounted at its upstream end on a fuel burner nozzle 12 by means of a part-spherical bearing 13 which permits limited pivotal movement of the flame tube about its upstream end, also relative longitudinal sliding movement. The downstream end of the flame tube 10 is of segmental form and is connected to the upstream end of the discharge duct 11 by means of flanges 14, 15 and a retaining ring 16. This connection permits limited movement of the flame tube relative to the discharge duct about the axis of the part-toroidel abutment surfaces of the flanges 14, 15. The downstream end of the discharge duct 11 is formed at its inner periphery with blocks 18 (Fig. 4) and a horizontally-disposed T-shaped member 17 extends between adjacent pairs of blocks being secured to support structure 9 so that relative radial movement can take place between the parts. A cover plate 19 is secured to the blocks 18 and provides a flange 19a which limits the radial movement of the T-member 17. The outer periphery of the downstream end of the duct comprises a flange 21 which co-operates with a flange 22 of the support structure so as to permit relative radial movement.
