Title: Improvements relating to a knit stretchable and retractable garment fabric
IPC: A61F13/08
Filed: 1958-03-05
Abstract: 871,833. Knitted fabrics. ALAMANCE INDUSTRIES Inc. March 5,1958 [Aug. 19, 1957], No. 7118/58. Class 74 (2). [Also in Group VI] Each of a plurality of courses of a tubular garment, such as a surgical stocking, is formed from at least three independent high-torque lively monofilament yarns (e.g. nylon yarns), the torque directions of all the yarns forming any one course being the same, but the torque direction of the yarns in some courses being opposite to that of the yarns in other courses. Thus, pairs of courses knitted from four S-twist yarns S-1 to S-4 may alternate with pairs of courses knitted from four Z-twist yarns Z-1 to Z-4. A fully fashioned blank may have a leg 12 and foot knitted by the two-carrier method, pairs of S-twist and Z-twist courses alternating. The plain narrowings 13, 14 may exceed the normal number, to provide a relatively narrow leg; and the number of calf narrowings 15, 16 may be such as to cause a relatively sharp reduction in fabric width. The turned welt 10 and afterwelt 11 are knitted with a single yarn carrier feeding a non-torque nylon yarn. The heel pockets 17, 18 are formed by widening and narrowing and the toe is formed by a conventional narrowing operation, to form a tail 21. Heel pockets, foot and toe may be reinforced by feeding non-torque yarn from the splicing carriers. To control the liveliness during knitting, the yarn cones are dipped into an oil bath before placing them on the machine, to deaden " static " and to make possible a greater yarn tension; and the yarn may pass over an oil supply wick on its way to the yarn carrier.

Abstract: 599,424. Valve generating and superregenerative circuits. HAZELTINE CORPORATION. March 12, 1946, No. 7736. Convention date, March 1, 1945. [Class 40 (v)] A U.H.F. oscillation generator comprises a valve of the grounded-grid triode type, a resonant circuit, a tap on which is connected to the valve control electrode and a phaseshifting network with one of its elements connected in series with the resonant circuit between the anode and the cathode. A theoretical circuit according to the invention comprises a valve 10, Fig. 1, with its control grid earthed and connected between the two condensers 12, 13 which, with inductance 11, form the resonant circuit. The phase-shifting network inductance 14 is connected between the cathode and the resonant circuit, and the capacity 15 between cathode and earth. It is shown that the resultant phase of the oscillatory voltage at the cathode is the same as that at the anode so that oscillations are sustained, the phase-shifting network being series resonant at a frequency substantially less than the operating frequency. In a practical embodiment, the inductance 26, Fig. 6, of the anode lead adds to the inductance 11 of the oscillatory circuit and the anode-grid interelectrode capacity 12<1> corresponds to the capacity 12. The phase-shifting circuit comprises the inductance 14' of the cathode lead and the cathode-grid interelectrode capacity 15<11>. To compensate for the phase shift produced by the input conductance of the valve a time-delay network 31 is connected between the inductance 14' and the capacity 13. The network 31 may be constituted by a line section comprising a signal choke within an earthed metal foil. The oscillation generator may form part of a super-regenerative receiver, Fig. 7.

Abstract: 196,262. Wildman Manufacturing Co., (Assignees of Howie, K.). April 17, 1922, [Convention date] Circular machines; yarn supply.-Relates to means for furnishing yarn to the needles for plating or other purposes at a uniform tension, capable, of adjustment. Each yarn x coming from an overhead bobbin or guide passes through a shiftable guide 1 betwen toothed frusto-conical furnishing wheels 5, 6 and through guides 9 - - - 12 to the work. The wheels 5, 6 are driven, and the guide 9 may operate a stop-motion, as described in Specification 191,365. The guides 1 and 11 are carried by a member 2 freely oscillatory under variations of tension, and the yarn is thus moved across the wheels 5, 6 to where the teeth are more deeply or less deeply in mesh according as the tension tends to increase or decrease. The action of the member 2 also compensates for stretching of the yarn due to increased tension. To give a damping effect the member 2 is made hollow with a perforated partition 17 between two compartments partly filled with mercury. To adjust the member 2 to suit different yarns, a counterweight 19, pivoted at 20 is adjustably clamped in different positions by a screw which also acts as a stop for the member 2. Each pair of wheels 5, 6 may co-operate with two members 2. The wheels 5 may be mounted on an adjustable bell-crank arm 13.
