Title: Improvements in circular knitted fabric or articles and in a method of and means forproducing the same
Inventor: OVERFIELD-COLLINS EDWARD
IPC: D04B9/26
Filed: 1954-02-01
Abstract: 776,825. Knitting. WILDT & CO., Ltd. Jan. 21, 1955 [Feb. 1, 1954], No. 2932/54. Class 74 (2). A continuous rotary knitted fabric simulating intarsia work has patterned areas 3 knitted mainly of a pattern yarn 5 only but with the edges of the patterned areas composed of knitted loops 6 of the ground yarn 2 and pattern yarn 5 and with the ground yarn floating as at 2a behind the loops of the pattern yarn 5 in the rest of the patterned area. The ground yarn 2 in addition, may, be knitted in an isolated wale or wales E in which case the pattern yarn is floated as at 5a behind the ground yarn loops. The pattern yarn is severed after it has been knitted in each course and reintroduced at the commencement of the patterned area in the next course. The fabric may be knitted on a single cylinder machine in which a pattern drum X operating selector bits effecting the actuation of needle jacks 19 cause those needles which are to knit the pattern yarn only to be raised to a height Y in which the ground yarn is fed beneath their latches. The remaining needles take the ground yarn 2 and are lowered without knitting it. Subsequently the selected needles take the pattern yarn 5 as do other needles selected, similarly as before by a pattern drum Xl (i.e. those needles which knit at the edge of the patterned area and knit both yarns) and all of the needles are then lowered to knit their respective yarn or yarns. The pattern yarn guide is operated in conjunction with a severing and clamping device 43 which clamps and severs the yarn when the guide 28 is removed from operation at the end of each partial course. A number of pattern yarn guides may be provided to enable further patterning by yarn selection to be made. The invention may also be applied to a rib machine of the cylinder and dial type although the patterning is confined to plain knitted fabrics knitted when the machine is knitting on the plain needles of the cylinder only and the dial needles are retained in an inoperative position. Specification 520,417 is referred to.

Abstract: A cationic active melamine resin is made by (1) condensing 1 mole of melamine with 5-8 moles of HCHO at 80-90 DEG  C. at pH 8-9 for 5-20 mins., (ii) etherifying the product with CH3OH in aqueous solution at 40-65 DEG  C. at pH 5-6.5 for 20-30 mins., (iii) condensing the product with formalin using 0.2-2 parts of formalin per part of etherified product at pH 8-9 and 60-90 DEG  C. for 5-30 mins., (iv) distilling off the water and excess formalin, (v) mixing the condensed anhydrous resin with CH3OH in a ratio of part of resin to 0.5-6 parts of CH3OH acidifying to pH below 2, stirring at 50 DEG  C. or below for 5-60 mins., neutralizing the resin obtained, removing volatile compounds, repeating said etherification stage if desired, and esterifying the etherified resin with a long chain acid having 10-20 C atoms or a mixture of such acids under reduced pressure at 160-200 DEG  C. until an ester having an acid number below 8 is obtained, and heating 10 parts of the ester obtained with 1-3 parts of an organic base, e.g. an ethanolamine. In the example, the esterified ether is reacted with triethanolamine, and the product mixed with paraffin.  A solid wax-like material results.  It may be emulsified in water acidified with acetic acid to yield a product suitable for water-proofing fabrics.

Abstract: 1,172,891. Optical apparatus; prisms. JUNGNER INSTRUMENT A.B. Jan.19, 1967, No.3007/67. Heading G2J. An optical instrument, such as a gun-sight telescope, comprises two transparent wedgeglasses joined at their opposed inclined faces to form a parallel-faced flat plate or disc 7, the joining surface being part-reflecting and supporting a reticle. Light from the target passes undeflected through element 7, the reticle appearing dark, but in poor light, the reticle is lit by lamp 9 from behind and appears bright. The joining surface is so inclined, say at 9 degrees to the parallel faces, that the rear illumination beam is reflected back along the telescope axis. The system may be used in an auto-collimator in which the telescope is directed at a plane mirror at the reticle is front-lit, or again in a reflex sight wherein a second objective directs light as to the back-lit reticle, the inclined joining surface reflecting light on to a second element 7 in the telescope axis. The joining surface of element 7 may be semisilvered, or the two surfaces may be separated by a spacer to form an air-gap.
