Title: Improvements in shuttleless looms
IPC: D03D47/00
Filed: 1933-01-19
Abstract: 413,683. Shuttleless looms with jacquard-controlled weft-guiding tubes. BRITTON, R., 48, Heath Crescent, Halifax, Yorkshire. Jan. 19, 1933, No. 1735. [Class 142 (ii).] In shuttleless looms for weaving fabrics adapted to be slit up to form Chenille for carpets, rugs, &c., the various wefts f, Figs. 1 and 2 are led from cheeses &c., through guide tubes e, e<1> on members c pivoted on pins c<1> on vertical members b arranged sector wise. The members c are normally moved by springs into contact with a stop g, but by means of connections h to a jacquard, any one of the members c can be rocked so that its tubes enter a slot in a fixed member i. A spring-controlled member j, Figs. 1 and 4, with notches of various depths is rocked by raising one or the other of jacquard hooks m, n. These have projections m<1>, n<1>, to engage the member j. One or the other of various shoulders j<1>,j<2> on the member j is thereby positioned for the lower tube e to rest on, and the appropriate one of the various tubes carried by the rocked member c is thereby located in the path of the weft inserting gripper u. The members c are connected to the jacquard hooks o through yielding connections. After a jacquard hook m, n, o has been raised, it is held raised by the engagement with a projection o<2> thereon of a spring-pressed plate p, to enable a particular weft to be repeated. When a change is required, a master hook r is raised, a projection r<1> thereon pushing back the plate p and releasing the raised hooks. The yarns passing through two adjoining tubes on a guide member may be tensioned by a single bent wire spring. The gripper may comprise two spring jaws U on a tubular member within which is a rod u<3> carrying a cam for opening the jaws and allowing them to close. The rod u<3> is operated as the gripper tube moves by a finger u'. This is actuated by sliding up an inclined pivoted tongue v and along an inclined surface v<1>, and also by a pin w on an arm w<1> fast on a pivotally mounted rod w<2> carrying an arm w3 with an inclined under surface, which is engaged by an abutment on the lay. The weft is gripped between the raised frame xl, Fig. 7, and a pivoted gripper x, which is controlled by a fixed abutment x<2>. The weft is cut, as the lay goes forward, by a spring-controlled cutting blade y. The cut weft is afterwards momentarily released from the holder, to enable it to be beaten up by the action of a cam member z. According to the Provisional Specification, each guide member c may carry one tube only.

Abstract: 312,103. Lanchester, F. W. Jan. 19, 1928. Spray carburettors.-Ignition timing is adjusted conjointly by induction-pipe suction and by a connection with the throttle mechanism, the advance effected increasing both with the suction and the throttle opening. The engine suction may act on a piston J, or on a bellows, the rod H being connected to a slotted. lever F. One end of a link C is connected to the arm B of the interrupter A, and the other to a pin movable in the slot E of the lever F. A throttle connection is afforded by the link N. In one modification the arm B may be slotted instead of the lever F; in another a further link connects the end of the link C to an unslotted lever F. In yet another modification, Fig. 9, a cam Q is slidably mounted on a shaft R. Angular movement is given to the shaft by a lever T corresponding to the lever F in the earlier construction; axial movement of the cam is brought about by connection of the arm Y to the throttle mechanism. The cam is two-dimensional and is engaged by a roller W carried by the lever V to which the timing lever X is attached.

Filed: 1967-01-16
Abstract: 1,169,394. Controlling injection moulding by compressed gas in the mould. G. FERRARI. 16 Jan., 1967 [14 Jan., 1966], No. 2305/67. Heading B5A. During injection moulding of a sole alone, or directly on to an upper gas, e.g. air, at a pressure higher than atmospheric but lower than the injection pressure is maintained in a mould. In operation, when an injection nozzle mates with an inlet sprue of the mould, a valve acts to allow entry of compressed air into the mould at a point diametrically opposed to the inlet sprue. Injection then occurs. An overpressure valve prevents high and uncontrolled air pressure building up in the mould, from which the air is gradually forced through its entry conduit, sintered metal discs permeable to the air but impermeable to the injected material being placed therein. A member detecting when the mould is full stops the injection. The mould comprises three interengaging parts, gaskets obviating air leakage therebetween. The injected material may be foamed polyurethanes or plastified or foamed polyvinyl chloride. When soles alone are produced, two thereof are formed in one injection cycle.

Title: Improvements in and relating to the production of intermediates for vat dyestuffs
Filed: 1929-01-23
Abstract: 332,907. Fairweather, D. A. W., Thomas, J., and Scottish Dyes, Ltd. Jan. 23, 1929. Drawings to Specification. Anthrahydroqninones, mono sulphuric acid esters of.-Mono-sulphuric esters of anthrahydroquinones are prepared by way of mixed 9: 10- diesters in which one ester group is a sulphuric ester and the other an acetyl, benzoyl or other acyl group, by first reducing the corresponding anthraquinone in the presence of a metal and a tertiary organic base, treating the product with pyridine sulphur-trioxide and an acylating agent for the formation of the sulphuric ester and the acetyl, benzoyl or other acyl ester respectively, and partially hydrolyzing the resulting mixed . 9 : 10-diester to split off the acyl group. The sulphuric ester group may be formed before, after or simultaneously with the other ester group. Alternatively the mono-sulphuric esters may be prepared by partially hydrolyzing the disulphuric esters of anthrahydroquinones, for example, by means of zinc and caustic soda solution, or hydrochloric acid. The presence of acetic anhydride in these processes facilitates the isolation of the product without substantial decomposition. According to examples (1) anthraquinone is reduced in pyridine and an atmosphere of nitrogen with zinc dust and acetic acid, and the product treated with acetic anhydride, then with pyridine sulphur-trioxide to obtain anthrahydroquinone-9- sulphuric ester-0-acetic ester, which is converted to anthrahydroquinone mono-sulphuric ester on warming with aqueous caustic soda; (2) 1-acetylammoanthraquinone is reduced as in (1) and treated with pyridine sulphur-trioxide, then with acetic anhydride to give 1- (or 4-) acetylaminoanthrahydroquinone-9-sulphuric ester - 10- acetic ester which is converted by warming with caustic soda. solution to 1- (or 4-)-acetylammoanthrahydroquinone-9-sulphuric ester; (3) the mono-sulphuric ester of 2-chloranthrahydroquinone is prepared by boiling the disulphuric ester with zinc dust and caustic soda, solution or with hydrochloric acid; (4) the mono-sulphuric ester of 2-aminoanthrahydroquinone is prepared by a similar hydrolysis of the 2-acetylaminoanthrahydroquinone-9 : 10-disulphuric ester.
