Patent GB-776521-A (GB)
Title: Making continuous fibres from a normally crystalline polymer latex
Inventor: LEBOEUF EDGAR WILLIAM
IPC: D01D10/04
Filed: 1955-10-25
Abstract: Strong fibres are obtained by depositing a thin narrow stream of a latex of an unplasticised and normally crystalline polymer or copolymer of a vinylidene halide or cyanide on a smooth, non-absorptive surface, drying the filamentary deposit, stripping it from the surface, heating it to a fusion temperature, chilling it and stretching the supercooled filament to effect orientation and crystallization.  The latex is an aqueous dispersion of a polymer of vinylidene chloride, bromide, cyanide, chlorobromide, chlorocyanide or bromocyanide, or a copolymer thereof with one another or with minor amounts of other monoethylenically unsaturated compounds such as vinyl chloride, vinyl bromide, vinyl acetate, acrylonitrile, methacrylonitrile, styrene, chlorostyrene, and methyl or ethyl acrylates or methacrylates, and is made by emulsion polymerization, the polymeric particles being temporarily amorphous when first formed and being substantially all under 1000   in diameter.  The dispersion is deposited while a substantial proportion of the polymer is still non-crystalline, deposition being effected by discharging the dispersion through a stylus or from the periphery of a thin driven disc on to a smooth moving belt or rotating drum.  Drying of the deposit may be effected by infra-red lamps, by heat conducted through the smooth surface or by circulating warm air.

Title: Improved manufacture of artificial leather and skin
IPC: D06N3/00
Filed: 1948-11-24
Abstract: 688,751. Artificial leather. CENTRAL ADAMAS SOC. PER AZIONI. Nov. 24, 1948. [Oct. 28, 1948] No. 30544/48. Class 96. Artificial leather is prepared by disintegrating a cellulaosic material into its individual fibres whilst under the influence of activators, admixing binders to give a pulp which is filtered, pressed into shape, and dried. The activators promote adhesion between the fibres and binders and are exemplified by zinc chloride, ammonium sulphocyanide or sulphate ion. Specified binders are rubber, rubber latex, synthetic resins e.g. polyvinyl acetate and chloride, natural resins or albumins, in amounts between 10 and 65 per cent. For greater elasticity and softness, casein, gelatine, butyl phthallate or tricresyl phosphate may be added, as also may drying and water proofing oils e.g. castor, linseed and colza oil. Fillers, e.g. organic or inorganic pigments, earth, talcum, natural leather or cork powder may also be present. In operation, fibrous materials, fillers, binders and activators are mixed in a gang of beaters 1, 2, 3 then passed to tanks 4, 5 where precipitation by means of 1.-5 per cent solution of tannic acid or formaldehyde or aluminium sulphate, chromate or bichromate, of the binders on to the fibres occurs. The pulp is filtered and then passes through a feeding tank 6, purifier 7, a fourdrinier and a web press 9. For thick plates the sheets on the press 9 are cut and placed on a platform where they are coated with formaldehyde then pressed and dried: For thin strips, the material from the press 9 falls onto a felt 13, Fig. 3, passed under suction drying boxes 17, between presses 18 and 19 where a formaldehyde coating is applied, dried in an unit 20 and wound on a reel 21. The ribbon is further treated by a first impregantion in a tank 28, Fig. 4, where it is softened, and then impregnated in a tank 29 with a solution of formaldehyde, zinc chloride, animal glue, glycerine and ethylene glycol. On passing into tank 41 containing precipitants the glue is insolubilised and when pressed and dried a high polish is obtained.

Title: Device for controlling gas turbine engines
IPC: F02C9/32
Filed: 1974-07-10
Abstract: 1462390 Automatic control of speed FIAT SpA 10 July 1974 [31 July 1973] 30561/74 Heading G3R A control system for the fuel supply of a gas turbine engine includes duplicated speed sensing arrangements 1, 3; 2, 4 providing a speed signal to a main control 6 where it is compared with a desired speed signal set on a potentiometer control 8 to provide an error signal which passes through a P1 circuit arrangement, whose gain can be varied by alteration of feedback resistor 9, to output point 26. The speed signal also passes to function generator 7 which includes operational amplifiers each having different non-linear characteristics and operates to modify the speed signal as the turbine accelerates on starting and provides a signal at output point 28. Thermocouples 150, 151 in the turbine provide an average temperature signal output from circuit 15 but on starting the selector 20 provides a signal corresponding to the highest of the temperatures at 150, 151 and the greatest signal passes through OR gate 22 to comparator 17 where it is compared with a reference signal derived from the discharge pressure of the compressor. The circuit 23 is a PID circuit and the feedback is such that when the temperature reaches the reference level the output drops to a lower limit. This output is compared with a reference from potentiometer 24 and the highest level signal selected and applied to the inputs of the duplicated minimum selector circuits 10, 11 together with the signals at points 26, 28. The lowest signal is used in control circuits 12 or 13 to supply a current to fuel valve 18. The speed voltage signal is derived from the frequency of the sensor output.

Filed: 1956-10-09
Abstract: 796,264. Strain indicating-apparatus; recording-apparatus. ORGILL, R. H. Oct. 9, 1956 [Oct. 20, 1955], No. 30701/56. Classes 106 (2) and 106 (4). [Also in Groups XXXIII and XXXVII] Recording - apparatus comprises a series of parallel electrical circuits each independently associated with a component of an aircraft and to each of which components is connected a switch 28 or 29 for completing the corresponding circuit when abnormal characteristics are exhibited by the component and means operated by each circuit for recording the abnormal condition. The switches for completing the recording circuits may be micro-switches 28 or " flexible plate " switches 29 (see Group XXXVII), used alone or in combination and fitted to the component itself or operated by bellows fitted to the component. Leads from the switches 28, 29 fitted to the various components are housed in a cable 25 terminating in a multi-connection plug 24 fitted in a complementary socket 23 mounted on the periphery of a housing 14 for the recording means 20 which are connected by leads 22 to the socket 23 and suitably marked readily to identify the corresponding components. The housing 14 comprises a metal sphere 15 with an outer fireproof flexible covering, packed with alternate layers of flexible asbestos and fibre glass 17 with an outer layer 16 of soft rubber with air pockets to increase buoyancy and covered with a hard rubber skin 16a. The inside of the sphere 15 is packed with sponge rubber 18 which surrounds a ring 19 of insulating material on which the recording means 20 are mounted. The recording means are preferably in the form of low resistance heater cartridges comprising resistance wire embedded in a small block of light coloured heat discolouring material such as paper or a plastic material and provided at each end with metal terminal lugs. The wire may have an S-bend or a coiled portion to concentrate the heating effect. The degree of discoloration of the cartridges indicates the sequence of the failure of a number of components because the circuits are in parallel and less current passes through each as more circuits are closed. A miniature tape recorder may be mounted in the centre of the sphere, which for safety is carried in the tail of the aircraft and may be forcibly ejected in the event of the aircraft crashing with a view to preserving the records. The circuit may also include a fuse 32, ballast resistance 33, master switch 31 for operation manually or by the pitot tube or throttle at a predetermined speed during take off, and a light 36 in the pilot's cabin to give visual warning of abnormal conditions in one or more components.

IPC: D01H7/44
Filed: 1923-12-11
Abstract: 223,083. Malloch, J. M. Dec. 11, 1923. Spindle apparatus.-Drag arrangements for bobbins in spinning, roving, winding, and like machines comprise a sole plate A, which supports the bobbin directly or by means of a washer secured thereto, and an adjustable brake band B<1>, of which one end is secured to a flange or a ring B on the sole plate and the other to a spring- controlled adjustable lever B<2>. As the bobbin rotates it imparts a turning-moment to the sole plate and so tensions the band, and, as the weight of the bobbin and the turning-moment increase, the lever B<2> turns slightly and so increases the arc of contact of the band, the frictional drag on the bobbin being thereby increased in a greater proportion than its weight. The lever B<2> is provided with a spring-handle B<4> adjustable in notches B<6> in the lifter rail to vary the initial arc of contact of the band, or a spring-arm on the lever may be arranged to engage another lever clamped to the lifter rail. A clearance space C is formed in the sole plate, the ends of which engage with the fulcrum of the lever B<2> or with one end of the other lever and serve as stops to limit its movement.
