Title: Improvements in and relating to pile fabrics and the method of making same
IPC: H05B3/68
Filed: 1933-12-05
Abstract: 432,883. Pile fabrics. BANISTER, X., 21, George Road, Braintree, Essex. Dec. 5, 1933, No. 34210. [Class 142 (iv)] These are made by folding fibrous material 10, Figs. 15, 15<a>, 18 and 20 about spacer wires 1, inserting strips of rubber 15<a> cut from a sheet 15 and serving as "wefts" into the bottoms of alternate loops, and applying a plastic coating such as rubber 41<a> to the back of the loops, and vulcanizing this coating to the loops and the wefts. An openwork fabric 46<a> and a coating of sponge rubber &c. 44<a> may also be applied. The fabric may be made double and be cut as shown in Fig. 27. The fibre from a reel &c. A Fig. 1, is fed into a housing B containing an oscillating loop folder 14, Figs. 15 and 18, and timed with co-operating oscillating cams 25, 29 whereby it is folded about spacer wires 1 inserted from shoots 4, 5 into slits 28 in the cams, by plungers 26, 21, on reciprocating carriages, the plunger 21 severing a thin strand 15<a> from the rubber web 15 and carrying it forward with a spacer wire. The spacer wires are shaped and are guided in a particular manner described. The looped fibres and spacer wires are fed along guides 1<a> between an upper steel roller 36 and a rubbercoated roller 37 adjustably mounted in eccentric bearings which flatten the loops. These pass to the coating rollers 40, 41, 42, Fig. 20, and Fig. 1, the rollers 40, 41 rotating faster than the roller 42 and faster than the speed of travel of the looped fibre whereby the plastic rubber is frictioned into the fibre &c. Fabric from a reel 46, Fig. 20 H, Fig. 1, and a sponge rubber backing may next be applied after which the coated fabric enters a tunnel J where the fabric and weft threads are united by vulcanization. The fabric finally passes above a brush L which opens up the loops freeing the top spacer wires. These re-enter the housing B through a shoot Q, whilst the previously released bottom spacer wires reenter it through a shoot P. The pile fabric next passes through a combing machine M and a shearing or cropping machine N to a reel O. The means for actuating from a motor the loop folders, the spacer-wire inserting devices, and the feeding devices for the webs 15, &c. are described. Separate driving motors are used for the brush L, &c. Instead of applying plastic rubber, rubber in liquid form &c. may be sprayed on the looped pile. The fibre may be folded about two abutting wires 130, 130<a>, Fig. 27.

Abstract: 1520455 Tube post systems SIEMENS AG 18 Aug 1975 [6 Sept 1974] 34223/75 Heading B8A In a tubepost system comprising sending/ receiving stations RS1, RS2, RS3 connected by a main line HR, each station includes destination selectors TF1, TF2, TF3 and control circuitry whereby in the presence of a shuttle at the despatch station a signal is generated to indicate whether or not despatch to the selected . station is possible and to store the selection until despatch is possible and stop other selections being made. Lights SL1, SL2, SL3 indicate that a shuttle may be despatched whilst lights BL1, BL2, BL3 indicate that a shuttle should not be placed in the respective station. In for example, despatch from station RS1, to RS2, a motor M applies suction to the tube HR to convey a shuttle past contacts bk3 which then cause a switch W3 to change over to connect the tube HR to the station RS3. The motor M then supplies compressed air to blow the shuttle into the station. The circuitry is described in detail.
Patent GB-899384-A (GB)
Title: Improved cellulose yarn or fabric and process of making same
IPC: D06M11/72
Filed: 1959-10-09
Abstract: Fibrous cellulose-acid complex material in the form of yarn or fabric, of the type in which the radical of a polybasic acid having at least one of its acid hydrogens replaced by a nitrogen-containing substituent or a sodium atom is linked to the cellulose at a hydroxyl group position of the cellulose molecule, is impreganted with a solution of a metallic compound and further treated to cause the formation in situ of an insoluble compound of the metal in the cellulose fibres to produce crease-proof properties, improved affinity for cationic dyes, e.g. Sevron dyes, decreased porosity or a wool-like hand which properties are durable to washing and dry cleaning.  The cellulose-acid complex material may be produced by treating the cellulosic material with a mixture of a polybasic acid, e.g. ortho-, meta- or pyro-phosphorous or phosphoric acid or phosphamic, phosphotungstic, sulphuric, sulphamic, phytic, malonic, phthalic, citric, pyroantimonic, dihydroxy-diphenic, molybdic, tungstic, telluric, selenic or fluosilicic acid, and a nitrogen-containing compound, e.g. urea, dicyandiamide, biuret, acetamide, cyanoacetamide, guanidine bicarbonate, aminoguanidine carbonate, biguanide, guanidine or mixtures thereof, the material being then frame-dried, cured at an elevated temperature, e.g. 250 DEG F.-400 DEG F., washed in hot water and again frame-dried.  The cellulose-acid-nitrogen complex produced may then be treated with caustic soda solution to produce the cellulose-acid-sodium complex. The cellulose-acid-nitrogen or cellulose-acid-sodium complex is then treated with a solution of a metallic compound, e.g. a salt of aluminium, tin, zirconium, titanium, silver, chromium, copper, nickel, iron, cobalt, calcium, barium or zinc, which is rendered insoluble in situ by raising the pH towards neutrality by continued rinsing with water or by the use of insolubilising agents, e.g. sodium silicate, sodium tetraborate, disodium phosphate, sodium benzoate and organic amines, such as triethanolamine.  The use of silver, chromium, copper, nickel, iron and cobalt salts produces characteristic colours in the resultant materials.  The material may then be rinsed and dried and subsequently treated with a suitable softener, e.g. a polyethylene emulsion, tinted, dried or "Sanforized" (Registered Trade Mark).  Yarns and knitted or woven fabrics made from natural cellulosic fibres, e.g. cotton and linen, and regenerated cellulosic fibres, e.g. viscose rayon, may be treated. Specifications 649,642 and 692,184 are referred to.

Title: Improvements in copying mechanism for producing polygonal forms by turning, boring, milling, or grinding
IPC: A62C4/00
Filed: 1922-12-15
Abstract: 212,655. CÚsar, J. Dec. 15, 1922. Lathes; copying and reproducing mechanism. - In the production of polygonal forms, either external or internal, in lathes &c. by copying mechanism of the type in which a rotating templet operates a copying lever which effects both the transverse movements of the tool holder and an oscillation of the tool arm to maintain the correct cutting relation between the tool and the work, the templet is mounted on a transverse slide which is carried on the tool slide, the two slides being movable relatively to each other to an extent determined by the templet the proportion between the movements of the tool and copying lever being adjustable through lever mechanism to vary the scale of reproduction. The frame 1 carries a longitudinal slide 2 having guides for a cross slide 4 upon which is mounted the tool slide 7 provided with a plate 8 formed with yoke members 9, 10. The templet slide 12 is carried on the tool slide and is connected through a bracket 22 with one arm of a lever 13, the position of the pivot being adjustable by a screw 17. The other arm of the lever is connected by a bracket 21 to the plate 8 on the tool slide. The templet is carried on a shaft 24 mounted on the slide 12 and comprises a frame 27 and a square plate 26 provided with corner studs 28 carrying rollers 29, the corners of the plate and frame being rounded off concentrically with the rollers. The templet is driven from the lathe spindle through gears (not shown) and a universally jointed shaft 32. The copying lever is mounted on a shaft 35 carried by the plate 8 and is provided with an arm 37 having a roller engaging the inner periphery of the frame 27. The tool is mounted in a holder on a slide 48 carried on a rotary slide 43, the oscillations of the copying lever being transmitted to the rotary slide to maintain the tool at the correct angle to the work by means of a toothed segment 39, gear 440 and toothed segment 42. The scale of reproduction is varied by adjusting the pivot of the lever 13. In operation, the cross slide is first adjusted until the ratio of the distance of the axis of the slide 43 from the work axis to the distance of the axis of rotation of the copying lever from the templet axis is equal to the linear scale of reproduction. The tool holder may then be advanced on its slide 46 until the work 52 is brought to the required size, the slide 2 being transversed along the work by means of a spindle 60. For milling a rotary tool is mounted on the slide 48.
