When knitting hose having heel pouches on a four feed circular machine, the heel pouches are formed by rotary knitting. The pouches comprise alternate complete and partial courses, and the ends of each partial course are locked to adjoining fabric by tuck stitches and intervening miss stitches. Partial courses are knitted by a group of needles H selected to knit at alternate feeds, e.g. 11. Spaced needle jacks 6 at the ends of the group are provided with nibs 6a overlapping several jacks. As the jacks 6 are raised they engage the butts 6b on some of the overlapped jacks to raise higher butts onto tuck cam 17. Needles associated with intervening jacks without butts 6b are not raised, and miss the yarn. The group of needles are raised prior to the next station to engage splicing yarn at feed 21 which is thus knit over the same extent as the partial courses. The partial courses together with any splicing may extend under the foot; and the length of such courses may be increased and/or decreased progressively. The base may be knit in a micromesh structure that be continued in the heel by selecting needles to tuck at the fourth station 12, and knitting on all needles at the second station.

Abstract: 484,092. Hydraulic transmission of power. SINCLAIR, H. (Alison, N. L.) Oct. 28, 1936, No. 29364. [Class 69 (ii)] In a hydraulic coupling of the F÷ttinger type, core guide means include or have the form of a ring mounted on one of the vaned members thereof and interrupted in such a manner as to permit, under certain working conditions, the flow of working liquid, across at least a part of the core space, from or to points in that vaned member between the flow and the return junctions. In one form, Figs. 7 and 8, the impeller has thirty uniformly-spaced, alternate long and short, radial vanes 3, 4 and fifteen core guide elements 14 carried by the vanes 3 ; the elements are of hollow semicircular section, of uniform length, and project equally on each side of the vanes 3 which extend across their interior. The gaps 13 between the elements 14 are of the same length as the elements. The runner has twenty-eight vanes 7, 8 the long vanes 8 carrying fourteen core guide elements 16. In a modification, Figs. 12 and 13, a solid core guide element 14a, 16a is carried by each vane of the impeller 2 and runner 9. The above constructions are stated to improve the working of the coupling, and also facilitate manufacture owing to simplification of the cores required in casting and are easier to clean of core sand and the like in the circuit passages. The invention is applicable to couplings having constant filling, to couplings in which the liquid content can be varied during operation, as by a scooptube as described in Specification 328,028, [Class 69 (ii)], or to couplings having automatic variation of the degree of filling, as described in Specification 385,086.

Abstract: 248,484. Grosvenor, J. E., and Picking, W. T. Dec. 9, 1924. Jacquards; comber-boards. In weaving designs repeating from the centre to the sides of the fabric, a comber-board is used having its cord-guiding . holes arranged in the ordinary way A from the left to the centre, but in a reversed manner A' from the centre C to the right, as shown, thus allowing the cards to be punched in duplicate, cards B being used in the ordinary way to produce the left half of a pattern, but being turned endwise as at B<1> to produce the right half of the pattern. The reversed arrangement of the holes in the part A<1> of the comber-board enables the reversed cards B<1> to produce a pattern which is the exact reverse of that produced by the cards B in the part A. The invention is illustrated as applied to a five frame design, the cards being sufficiently wide for fifteen holes a - - - e to be made therein to control three courses, the first fifteen controlling the three courses 1, 2, 3 or 1x, 2x, 3x, and the next controlling the three courses 4, 5, 6 or 4x, 5x, 6x and so on. In the case of breadth goods intended to be sewn together &c. after weaving, only one half of a complete design being woven at one time, the order of the holes in the comber-board is reversed at C, but in this case the cards or portions thereof used for weaving the right hand half of the breadth goods are punched in a reversed manner to correspond with the reversed order of the holes in the comber-board. The point of reversal C may be situated otherwise than at the centre.

Title: Improved method of sulphonating copolymers of monovinyl-and polyvinyl-aromatic compounds
IPC: C08F8/34
Filed: 1949-11-18
Abstract: In a process for sulphonating a benzene-swellable copolymer of one or more monovinyl aromatic compounds, e.g. styrene, o-, m- or p-chlorostyrene and dichlorostyrene, and 3 to 20 per cent of one or more polyvinyl aromatic compounds, e.g. divinyl and methyl- or ethyldivinyl benzene, the copolymer is first swelled by an organic liquid such as benzene, toluene, xylene, ethyl-, isopropyl-, or chlorobenzene, tetrachlorethane and tetrachloroethylene.  The copolymers may be made by heating in bulk, or in solution in an inert solvent, e.g. benzene, toluene, ethyl benzene or acetone, which may also act as swelling agents. The copolymer may be swelled as a continuous mass, rods, sheets or as granules, which may be obtained directly by polymerization in an aqueous suspension containing protective colloids or thickenging agents, e.g. starch, gum tragacanth, methyl cellulose, or the sodium salt of carboxymethyl cellulose.  An example describes the preparation of a granular terpolymer of divinyl benzene, ethyl-vinyl benzene and styrene using benzoyl peroxide as a catalyst.  Sulphonation may be effected by concentrated or fuming sulphuric acid or chlorosulphonic acid and the product may be obtained as the free sulphonic acid, or by the addition of a concentrated aqueous solution of an inorganic salt, e.g. sodium chloride, as a salt, the concentration of ionizable solutes in the aqueous liquor in contact with the product being gradually decreased by dilution.  The products may be used as cation-exchange resins.  U.S.A. Specifications 2,089,444 and 2,366,007 are referred to.
