Title: Artificial fibres and production thereof
IPC: D01F2/08
Filed: 1971-01-08
Abstract: 1315471 Coated microcapsules JAPAN EXLAN CO Ltd 8 Jan 1971 [10 Jan 1970] 1101/71 Heading B2E [Also in Division B5] A method for producing an artificial fibre, which contains 0.1 to 30%, preferably 0.5 to 20%, by volume of particles comprises adding to a spinning solution of a fibre-forming polymer particles having a particle diameter of 0.5 to 30 microns, preferably 1 to 20 microns, which particles comprise a fibre modifier, and the surface of which particles is coated with a layer of a film-forming polymeric substance different from the polymer of which the fibre is composed which polymeric substance is non- reactive with said modifier and is substantially insoluble in spinning solvents used in the manufacture of said fibre, or can be made insoluble in such solvents by a curing or crosslinking step and then extruding said spinning solution through a spinnerette into a coagulating medium. The spherical particles (microcapsules) in which the coating layer has a thickness of 0.01 to 0.5 micron contain a fibre modifier can be prepared either by the coacervation method in which the modifier to be enclosed is dispersed in a continuous phase and the phase separation of a solution of a substance to be used as a coating material is utilised or by the interfacial polymerisation method in which a polymeric film is obtained by polymerising a monomer in the presence of a catalyst, on the interface of a continuous phase of the monomer and a fibre modifier dispersed in the continuous phase. Examples of film-forming substances are substances which can be rendered so by such treatment as by adding a cross-linking agent or curing agent are proteins, synthetic polymers, natural or partially processed colloidal substances and acid-group containing synthetic polymers. Synthetic or natural polymers may be used for forming the fibre and examples of synthetic polymer substances are polyamides, polyesters, vinyl polymers, acrylic polymers and of natural polymers cellulose and cellulose acetate. In the case of the acrylonitrile polymers representative solvents are for organic solvents, dimethyl formamide, dimethyl acetamide, ethylene carbonate and dimethyl sulphoxide, for inorganic solvents concentrated aqueous solutions of inorganic salts, e.g. sodium thiocyanate, zinc chloride, lithium thiocyanate, ammonium thiocyanate and calcium chloride, and nitric acid. The spinning solution may also be prepared by dissolving an acrylonitrile polymer or copolymer in a concentrated aqueous solution of a thiocyanate. The fibre modifier is to physically and/or chemically modify or improve the properties of the fibre, e.g. sanitating agents, flame-resisting agents, pearl pigments, luminous substances, deodorants, softeners, perfumes and antistatic agents may be introduced.

Title: Improvements in or relating to control apparatus for laundry drying and/or ironing machines
Inventor: DAWE LAURENCE JOHN
IPC: D06F34/08
Filed: 1951-01-18
Abstract: 702,147. Photo-electric control systems. DAWE, L. J., and BAKER PERKINS, Ltd. Jan. 16, 1952 [Jan. 18, 1951], No. 1438/51. Class 40 (3). [Also in Group XXXV] , The speed at which damp articles pass through a drying and/or ironing machine is adjusted in accordance with the amount of steam rising from the heated articles, so that all articles emerge at approximately the same dampness. The steam is detected photo-electrically. As shown damp articles pass from a conveyer C on to a heated bed A in a number of recesses of which turn rollers B. The articles pass between the rollers and the bed finally passing to a receiving conveyer D. The rolls are driven by a motor E the speed of which is adjusted by rotation of its brush-gear by an auxiliary motor E1. The steam is detected by a light beam which passes from a source F across the bed to a photoelectric cell F1. This arrangement may be situated at the entry to or exit from the rolls, the type of control varying accordingly. The light sources consist of as many lamps as there are lanes of articles passing through the machine. Contacts in the machine operated by the work switch in an extra lamp as each lane is occupied by an article. Control circuit.-The photo-electric cell controls a relay G which energizes one of thermal delay switches H1, J1 according as the steam density is above or below the correct value. These switches energize one of a pair of relays O, P, each having a contact in series with one of the fields E2, E3, of the load adjusting motor. Thus the speed of the roll drive motor is increased or reduced according as field E2, E3 is energized. A switch M is provided which when in its lower position enables either of these motor fields to be closed manually by operation of switches Q, Q1. To disconnect the field of the brush-adjusting motor when no lane is occupied for an appreciable time a number of contacts V2 . . . V5 are provided to short circuit relays R ... U unless an article is passing through the lane in which this contact is situated. When a lane is empty one of relays R to U closes a series contact in the circuit of a further R relay N after a time delay. Relay N thus operates only when all the lanes are empty for an appreciable time and then disconnects the fields E2, E3 of the brushadjusting motor. The relays R to U also operate to switch in light sources X ... X3 as an article enters each lane thus if all lanes are occupied all four lamps are illuminated. Specification 685,951, [Group VIII], is referred to.

As applied to the apron mechanism of a saddle Fig. 3 shows a twelve speed change gear comprising a pair of gears movable by a rod 47, a triple gear movable by a rod 48 and a double gear movable by a rod 49. The drive is transmitted to the saddle and cross-slide feeds by a worm 46a and friction clutches as described in Specification 524,441. In some cases the last double gear and its rod 49 are omitted six speeds only being thus obtained. A selector mechanism for this form comprises slides 59, 59a, carried by an extension of the apron and provided with shafts having fingered discs 61, 61a, at one end and spiral gears 61b at the other meshing with gears 64 mounted between ears on the slides and splined on a shaft 63 provided with a setting knob and indexed collar 63a. The setting is effected when the slides are separated as in Fig. 5 and on actuation of a shaft 65 having a two armed lever 66 links 67 close the slides which then cause the selected fingers to control the positions of the short arms of bell cranks 69, 69a as in Fig. 8. The longer arms engage slots in the rods 47, 48. The shaft 65 may be worked by hand or by linkage from a three armed lever operatively connected with the feed control levers as described in the prior Specification. Modifications are described for controlling three rods 47, 48, 49. In this case the fingered discs have twelve sets of fingers each controlling three bell cranks. To avoid interference between sets of fingers adjacent the operative position the discs are skewed in opposite directions or in a further modification are offset laterally. Similar means may control the saddle or headstock change speed gearing for driving the spindle.

Title: Improvements in combustion control of fuel burners for pulverised fuel or other generally opaque fuels
IPC: F23N1/02
Filed: 1960-01-21
Abstract: 904,758. Photo-electric control of burners. AISH & CO. Ltd., KYNASTON, J. R., and HATFIELD, J. C. April 21, 1961 [Jan. 21, 1960], No. 2232/60. Class 40 (3). A system for controlling the combustion of pulverized coal or other generally opaque fuel, such as heavy oil, injected into a furnace from a burner B, comprises two photo-cells 1, 2 located in the furnace wall, respectively, at a position prior to the desired position of combustion initiation and at a position where flame should be established, in conjunction with means responsive to the signal differential from the cells for automatically adjusting the supply of air or fuel necessary to initiate and support combustion at the predetermined position in the furnace. When the flame is correctly established, the cell 2 being illuminated, and the cell 1 being in the dark condition, the cell outputs provide a signal differential in a predetermined sense, and other conditions, such as pre-ignition or failure to ignite give rise to a much different derived, or resultant signal which may be zero, or the respective signals approximately equally balanced. The output from the cells 1, 2 is fed to a thermionic bridge circuit 3 connected to a C.R.T. 4 and to a moving-coil meter 5 for the purposes of display and indications of the positional conditions of the flame. The output of the bridge 3 is also fed to a cold-cathode valve bridge 6 connected by leads 7 to a combustionadjusting device, which may be a motor operating an air supply fan or controlling the fuel supply. A timing circuit 8 can be included so that a warning device 9 is operated if the flame position moves outside the area defined by the photo-cells for a period of time in excess of a predetermined interval. In a modification, a timing device 10 controls the cold-cathode bridge 6 to pass its output over the leads 7 at predetermined periodically occurring intervals to prevent over-correction of the faulty condition. In the case in which the established flame is relatively long, subsidiary control photo-cells may be interposed between the two cells 1, 2 which are located respectively at a point prior to the position of combustion initiation and the point where the flame should be established.
