Title: Improvements in circular knitting machines and fabrics produced thereby
IPC: D04B9/26
Filed: 1934-11-10
Abstract: 447,325. Knitting. LEVIN, N., 182, Pernnington Avenue, Trenton, New Jersey, U.S.A. Nov. 10, 1934, No. 32461. Convention date, Dec. 6, 1933. [Class 74 (ii)] For making vertically striped ribbed and warp fabrics one or more sets of yarns are used, with or without a ground thread and these yarns pass through holes 52, 53 formed in a ring 51 in circles eccentric to, and substantially of the same diameter as the needle circle. The distance between the centres is adjustable and determines whether each yarn wraps round two needles or one only. If a ground yarn is supplied to all the needles, the wrap yarns being fed to the cylinder needles, a vertically striped rib fabric is obtained, but if the ground yarn is omitted and the wrapping extends over two needles a plain warp fabric of the kind shown in Fig. 6 is obtained. If each needle in every course is supplied with a wrap yarn in addition to the ground yarn, a run-proof fabric is obtainable. By selecting needles, fabrics having combined wrap and tuck stitch designs are obtainable. Fig. 3 shows a rotary needle cylinder 59 and independently driven offset wrapping member 62, but the invention may also be performed on a dial machine with rotary cams 12, 13, and stationary ring 51. Jacks 16, individual to each needle 14 and slidable in the same tracks are acted on selectively by a battery of cams 18 to form tuckwork &c. The dial 11 is fixed at 20 to a stationary central shaft 19 surrounding which are tubular shafts 21, 22. Shaft 21 is rotary and carries the dial cams 13. Shaft 22 is stationary and is carried by a yoke 26, which rests in a ring 24 carried by posts 23. Seated within the ring 24 and connected to it by adjusting screws 30 is an annular ring 29 on which is mounted, with facilities for adjustment radially, a ring 34. A socket 38, on which is bolted the wrap ring 51, is mounted loosely within the ring 34 and is prevented from rotating therewith by the engagement of an arm 41 with the yoke arm 26. The arm 41 may be adjusted in position, circumferentially, by hand. Specification 300,605, [Class 74 (ii)], is referred to. According to the Specification, as open to inspection under Sect. 91, the wrap means may comprise dependent fingers secured in a top ring and provided with butts, actuated selectively by a central, vertically movable cam. This subject-matter does not appear in the Specification as accepted.

Gauging apparatus for testing the relative setting of parts of a machine, e.g. a knitting machine, comprises a plurality of different feelers 23, 30, 31 adapted for suitable association with respective parts of the machine, a micrometer 13 for relative adjustment of the sections into and out of testing relationship with the parts, and electrical means to indicate when the parts are in testing relationship. The base 2 of the gauge is clamped by screws 3 and a locating fork 6 to a bar 4 of the knitting machine. The body 8, secured to but insulated from the base 2 carries a spring loaded plunger 10 which slides horizontally in a tube 9 and is adjustable by the micrometer 13, 14. The gauging head, e.g. 15 in Fig. 1 and 25 in Fig. 3, is releasably secured by a screw 17 to the plunger 10. The head 15 carries a block 19 vertically adjustable by means of a screw 20 on a supporting bar 18, the feeler 23 being mounted in the block 19. In the head 25 the feeler 29 is mounted on the end of a curved arm 28 and has two contact points 30, 31. When the feeler 21 or 29 contacts the machine part an electrical circuit is completed, operating a signal such as a bell or lamp. Where the machine part is a poor conductor the construction of the head is modified, e.g. as in Fig. 6, a spring 228 carried by an insulating block on the arm 28 being normally out of contact with the point 31 but when pressed against the point by a part of the machine completing the indicator circuit. Two micrometers may be provided for adjustment in different directions.

In the crystallization of a constituent from a liquid mixture by direct heat exchange with an immiscible liquid coolant, the mixture is supplied to an intermediate section of a column through an inlet 1 and passes upwards in countercurrent to coolant supplied through an inlet 2. The column comprises a number of temporary mixing zones, each having a rotary bladed stirrer 9 and each being separated by a conical baffle 7 having a plurality of apertures closely spaced around its apex (Fig. 2A). From each zone, mother liquor passes upwards through the apertures and a crystal/coolant mixture passes downwards around the baffles. The upper part of the column comprises a further stirrer within a restricted zone, into the space above which the coolant is sprayed and from quiescent liquid around which spent mother liquor is withdrawn through an outlet 4. The lower part of the column comprises a still further stirrer above a settling zone from which crystals and coolant are removed through outlets 3 and 10 respectively, the crystals being entrained in recycled mother liquor supplied through an inlet 5. The baffles may have a half conical angle of 45-85‹. The stirrers may be rotated at 20-50 rev/min. The mother liquor may be recycled at a rate of 2-5 times the weight of crystals withdrawn. The process may be applied to the crystallization of p-xylene from a liquid hydrocarbon mixture using an aqueous calcium chloride solution as coolant. The apparatus may be modified to enable upward flow of coolant and downward flow of liquid mixture. Water may be thereby purified by crystallization using a lighter coolant.
