Patent GB-883545-A (GB)
Abstract: 883,545. Making moulds. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 6, 1958 [Nov. 14, 1957], No. 35554/57. Class 87(2). [Also in Group XXII] A method of manufacturing a mould or core consists in making of a refractory material and an aluminium phosphate binder, a mould with an oversize cavity or an undersized core, placing a pattern in the mould or around the core, filling the interspace with a slurry containing a solution of silica in alcohol obtained by the hydrolysis of ethyl silicate, and removing the alcohol by igniting it. Initially, a wood or metal pattern 1 is embedded in "Plasticine" (Registered Trade Mark) 2 coated with wax or grease. A plaster cast 5 is made and the whole assembly is then inverted and the Plasticine removed. An # inch layer of clay 7, Fig. 3, is pressed on to the pattern and a mould 9 is made of plastic zircon sand and aluminium phosphate, as in Specifications 812,352 or 847,909. One more of these sand moulds 9 are made than are required, e.g. for 50 castings, 51 half moulds are made the moulds being hardened by ammonia gas. The clay 7 is next removed, the mould 9 is drilled and the part re-assembled as in Fig. 4, the pattern being well waxed and polished. The series of half moulds are then completed by placing them one-at-a-time on top of the pattern and filling the interspace with an ethyl silicate fine slurry made as in Specification 716,394. Each mould is ignited as soon as it is stripped. The last half mould, however, is left in position, is inverted and the plaster coat 5 is removed. The other halves are then made in the same way. Two pattern plates may be used to speed the process. The phosphate may be prepared by the reaction of phosphoric acid or aluminium oxide in which case both aluminium dihydrogen phosphate and di-aluminium hydrogen phosphate may be used as a binder. The backing and lining may be interlocked mechanically. Specification 774,184 also is referred to.

Title: Tufting machine yarn feed control system
Inventor: WOODCOCK DOUGLAS GEORGE
IPC: D05C15/18
Filed: 1989-03-10
Abstract: Yarn (50) is fed to the needles (12) of a tufting machine by way of a driven roller (36), which can be driven selectively at slow or fast speeds by a clutch mechanism (40) so as to produce patterns of short/long tuft length, or in the case of a machine where the needle bar (10) is longitudinally displaced (arrow 20) so as to compensate for such sidewise movement and provide even tuft length. Changeover of the clutch from slow to fast speed is effected in each case by movement of a mechanical actuator (e.g. 42, 44) past a sensor or proximity switch (46). Where the needle bar (10) is displaceable the actuator (42, 44) is preferably associated with the displacement mechanism, e.g. mounted on a cam (22) which controls the displacement sequence, so that yarn feed is synchronised therewith. Alternatively the actuator may be associated with the needle bar vertical reciprocation mechanism, or a fabric displacement mechanism (if present). <IMAGE>
