Abstract: 917,233. Coated polyamide films. BRITISH CELLOPHANE Ltd. Nov. 22, 1961 [Dec. 12, 1960], No.42715/60. Class 140. Heat-sealable. moistureproof wrapping material is produced by coating at least one side of a polyamide film with a coating composition comprising (a) an organic solvent soluble vinylidene chloride copolymer prepared by copolymerizing vinylidene chloride with one or more copolymerizable ethylenically unsaturated monomers wherein the vinylidene chloride monomer is present in an amount within the range 85 to 95% by weight and (b) between 1 and 40% by weight based on the weight of the vinylidene chloride copolymer of a polymeric product obtained by the copolymerization of 80 to 95% by weight vinyl chloride, 5 to 20% by weight vinyl acetate with or without up to 2% by weight of maleic acid or maleic acid anhydride, dissolved in a volatile organic solvent, followed by removal of the solvent by evaporation.

Title: Improvements in and relating to yarn clearing devices
Inventor: GREGORY JOHN EDWARD REGINALD
IPC: A45D1/02
Filed: 1964-10-21
Abstract: 1,069,166. Yam clearing apparatus; counting and recording. FLIGHT REFUELLING Ltd. Oct. 20, 1965 [Oct. 21, 1964], No. 42929/ 64. Headings D1F and D1J. Changes in the diameter or thickness of textile yarns are determined by causing such changes to deflect a pivoted feeler, such deflections being used to change the intensity of a magnetic field to which a magnetically operative reed switch is responsive. In Fig. 5 the running yarn 4 passes between a ceramic reference plate 1 and an arm 11 pivoted at 12, the arm 11 carrying a ferrous vane 13 normally arranged to lie intermediate a permanent magnet 14 and a magnetically operable reed-type switch 15. When the thickness of the yarn increases, or a slub occurs, the upper end of the arm tends to follow the running yarn 4 and the vane 13 is then displaced to allow the permanent magnet 14 to operate the switch 15 and so close the energising circuit of a solenoid operating a yarn cutter. In Fig. 6 (not shown) the pivoted arm 34 carries two permanent annular magnets 32, 33 within each of which is located a magnetically actuated reed switch 35, 36, the whole being so arranged that if the yarn exceeds a predetermined diameter the arm 34 pivots in one direction in a manner causing magnet 32 to operate reed switch 35 and if the diameter of the yarn is less than said predetermined diameter the arm 34 pivots in the opposite direction in a manner causing magnet 33 to operate reed switch 36. The switches preferably operate a cutter. Each embodiment includes a control knob enabling the operator to pre-set the detector to operate in accordance with a predetermined cotton count. The reed switches are hermetically sealed and counting or recording means may be included to indicate the number or frequency of slubs in the yarn. The cutter mechanism may cut the yarn on both sides of a slub to remove the fault entirely from the yarn and may be associated with a yarn joining mechanism.

Title: Numerical control system
IPC: G05B19/418
Filed: 1972-09-19
Abstract: 1396024 Automatic control of position ING C OLIVETTI & C SpA 19 Sept 1972  [30 Sept 1971] 43382/72 Heading G3N A system for the numerical control of a plurality of machine tool positioning units by a single programme employs a first storage device for an address and a second storage device for numerical data, and for each positioning unit there being a decoding device responsive to a address for enabling a selected register of a plurality of registers for the axes of the positioning unit. As shown, a punched tape reader 100 derives address, position and auxiliary function data which is decoded in a diode matrix 104. The recognition of an address by the matrix causes the data to be fed to and held in, a flip-flop register 108 for subsequent transcoding in a circuit 112, comprising a diode matrix and a flip-flop register. The staticized address is gated through an element 114 to an output 20 and accepted through a gate 130 by an appropriate positioning unit of a machine, not shown, when that unit is ready to receive dimensional data. The matrix 104 on recognition of numerical data, enables a gate 118 to pass the data into a recirculating shift register 116. A gate 122 is enabled by a signal indicating that the reader is not emitting an address and call-up signal from the positioning unit to feed dimensional information through a gate 134 into a selected register 136 of a plurality of registers, one for each axis of the positioning unit. An auxiliary function code is detected by a matrix 124 which enables a gate 126 to pass auxiliary function data into a register 128, from which it is fed to an auxiliary control unit, not shown, for the machine tool. The timings of the reading unit and positioning unit are independent, but the advance signal for the reader may come from a positioning unit immediately after the storing of the data in the register 136.

Abstract: 1,126,215. Mercuric sulphide; sulphur. SOC. INDUSTRIALE CATANESE S.p.A. 15 Oct., 1965 [20 Oct., 1964], No. 43859/65. Heading C1A. A composition for the purification of gases contaminated with mercury comprises either mercuric sulphide and sulphur supported on a carrier which is inert to the purification reaction, e.g. activated carbon or alumina or crystalline sulphur partially coated with the mercuric sulphide. A composition containing mercuric sulphide and sulphur may be used for the purification of gases contaminated with mercury by contacting the gases with the composition, preferably at space velocities of 10,000, 3000-4000 or 8000 volumes of gas per volume of composition per hour. The composition may contain 60-80 mg. of HgS and from 5-10 mg. of sulphur per gram of carrier. The composition may be prepared either by soaking crystalline sulphur in aqueous mercuric chloride solution and treating with a gas containing excess hydrogen sulphide, over that required to convert the mercuric chloride to sulphide, or by soaking an activated carbon or alumina carrier in aqueous mercuric chloride solution and treating with a gas containing excess hydrogen sulphide and oxygen. The composition is regenerated after absorption of mercury by treatment with a gas containing hydrogen sulphide, in an amount over that required to convert the mercuric chloride to sulphide, and oxygen. Examples show the removal of contaminating mercury from hydrogen and nitrogen.

Abstract: 1,088,243. Endless conveyers; stacking- machines. ABJORN ANDERSON A.B. Nov. 3, 1964 [Nov. 6, 1963], No. 44797/64. Headings B8A and B8C. Bricks to be stacked on a carriage (31) (Fig. 3, not shown) are arranged in rows of a predetermined sequence after being fed from a kiln (not shown) by a conveyer 1. The bricks are backed up against a stop 9 formed by the vertically-oscillatable framework of an endless conveyer 6. The rise and fall of the conveyer 6 is derived from a cam wheel 25, the profile 26 of which is arranged in accordance with the desired brick sequence. The conveyer 6 runs at a faster speed than the conveyer 1 and at a faster speed than a following conveyer 18 which has flights 19. The bricks thus collect in the desired sequence on the conveyer 18 and are transferred by a reciprocating pusher (29<SP>1</SP>) operated by a crank (34) (Fig. 4, not shown) driven by a motor (40). The bricks are pushed through aligning guides (42) on to a conveyer (30) from which the bricks are transferred to the carriage (31) by a gripper (not shown). There may be a second system identical with the above but feeding towards the carriage (31) in a direction at right angles to the conveyer (30) of the first system. This obviates the need for transferring gripper to be rotatable.
