Title: Coated glass fibres and elastomeric products formed therewith
IPC: C03C25/10
Filed: 1970-11-02
Abstract: 1312330 Coating glass fibres OWENSCORNING FIBERGLAS CORP 2 Nov 1970 [20 Nov 1969 21 Nov 1969] 52021/70 Heading DIP A process for coating glass fibres with a material comprising an organic polymeric polysulphide and/or a resin formed by the condensation reaction of an aldehyde with a phenol having a substituent containing a sulphur atom. Examples of the phenol are mercapto phenol, 4-(methylthio) metacresol and 4 (methylthio) phenol. The coating material is present in an amount corresponding to 5 to 25% by weight of the glass fibres. The coating material also includes a compatible elastomeric material, e.g. vinyl pyridine-butadiene-styrene terpolymer, a resorcinol aldehyde latex and a natural rubber latex. More complete protection of the individual glass fibres and a fuller coordination with the elastomeric material in the continuous phase is achieved by including in the size composition an anchoring agent, e.g. gamma-aminopropyltriethoxy silane or other silanes or Werner complexes in which the carboxylate group coordinated with the trivalent nuclear chromium atom contains an amino or epoxy group. The anchoring agent constitutes 0.1 to 3.0% by weight and preferably 0.1 to 1% of the size composition. The glass fibres may be in the form of a bundle and contain a thin size coating on the surface. Water is incorporated in the impregnating composition which has a solids content of 10 to 50% by weight. The final product may constitute an elastomer as the continous phase and treated glass fibres distributed within the elastomer. In performing the process the glass fibres may be sized by passing a wiping pad that is constantly wet with the form size composition and then they are gathered into strands which are either air dried or at a temperature of 150 to 250‹F. The sized strands may be treated with the polysulphide composition by impregnation in a bath, removing excess composition by passing through a roller or die and drying in an air oven at ambient temperature, but preferably 150 to 350‹F for 1 to 30 minutes.

Title: Improvements in racked programming control means
Inventor: STRONG BARRIE
IPC: D04B15/66
Filed: 1967-12-06
Abstract: 1,246,265. Knitting machines. WILLIAM COTTON Ltd. 25 Nov., 1968 [6 Dec., 1967], No. 55518/67. Heading D1C. [Also in Division G3] A programme control device comprises a main rotary rack mechanism for stepping on a punched chart and a plurality of auxiliary rotary ratchet devices, which are operated selectively for rendering the main rack mechanism inoperative for predetermined periods. As shown a punched chart is stepped on by a ratchet wheel 1 actuated by a pawl 2 on a lever 20, pivoted at 7, connected to a rod 8 operated by a cam follower lever 8a engaging a cam 8b on a main shaft 6g of a straight bar knitting machine. The chart is read by a feeler 3 having pins co-operating with the holes, intermittently applied to the chart by a lever 4 rocked, at times required for every course, by a cam follower 6e engaging a cam 6f on the shaft 6g. Also pivoted at 7 are discs such as that having notches 13a, to which are secured ratchet wheels such as 15. The wheel 15 is actuated by a pawl 17 carried by a pivot 19 on the lever 20. The numbers of teeth on the ratchet wheels and the notches in the discs are so determined that at no time can more than one control point of each disc be in register during a revolution thereof. A required repeat for a number of courses is indicated when a particular hole in the chart registers with the feeler 3. The next operation of the crank 6 lowers the feeler 3 to allow clockwise movement of a lever 35 permitting anti-clockwise movement of a latch 28 so that a hook 28a engages a peg 30. During this operation a peg 6h of the crank 6 has been moving in a slot 34a of a link 34 and finally rocks a lever 32 to pull the engaged latch 28. The latch 28 through a member 21, causes the pawl 17 to engage and turn the ratchet wheel 15, on operation of the cam 8b. As the disc turns a projection 9c of a lever 9 is pushed clear of the notch 13a causing a peg 11 to move the main pawl 2 clear of the ratchet wheel 1. The programming chart is held stationary while the notched disc is racked step-by-step by the pawl 17 and the cam 8b until the required number of courses is completed when the next notch is engaged by the arm 9c. The pawl 2 is then pulled back into engagement with the main ratchet wheel 1, which is thereupon racked by the cam 8b for stepping the programme chart. The programming chart is used in a programme control system of the type wherein feelers movably co-operate with punch holes in the chart to selectively actuate electric control switches.
