Title: Improvements in or relating to methods of knitting
IPC: D04B9/18
Filed: 1945-07-25
Abstract: 600,947. Knitting. HEMPHILL CO. July 25, 1945, No. 19053. Convention date, Aug. 12, 1944. [Class 74(ii)] A method of knitting upon a circular independent needle machine includes moving the sinkers inwardly soon and far enough for yarns to be drawn over their backs; feeding a body yarn and, above it, a plating yarn to the needles; drawing these yarns over parts of the backs of sinkers then radially motionless (which parts all have the same height) and through the needle loops of the previous course; casting off the previously formed needle loops by the sinkers acting on the sinker loops of that previous course only; and causing the newly drawn sinker loops to pass from the sinker backs, up and over the nibs to the throats. Plating yarn 6 and body yarn 7 for the leg and instep of a stocking are fed by an auxiliary yarn lever 5, and the plating yarn is positioned above the body yarn on the needles. Loops of both are drawn over the flat backs 41 of stationary sinkers 39, remain there whilst the previous course is cast off by the sinkers acting only on the sinker loops of that previous course and then, by a withdrawal of the sinkers, are caused to pass up over the tops of the sinker nibs 42 to the throats 40. A wrap yarn 27 (or a number of such yarns) is fed from a rotating wrap spindle 10, to selected needles, and is positioned on the needle or needles above the plating yarn. When a wrap yarn is fed to a group of needles it is also drawn over the sinker backs. During rotary knitting, the wrap yarns are fed over a horn 11, and during reciprocatory knitting they are fed alternately over horns 11 and 12, which are shogged circumferentially from the sinker head friction ring and are raised into operative position or lowered by the co-operation of pins which they carry with cam-ways 22 in a stationary arcuate plate 23. The sinkers are drawn out and immediately moved in again, during reciprocatory knitting, by a centre sinker cam point on the auxiliary side: the needle loops are cast off during the action of one or other of sinker cams 55, 56. At the main side of the machine, loops are drawn in the sinker throats. Two flopper cams 60, 61 are here provided for moving in the sinkers earlier than usual after they have been drawn out by the centre cam 57 so that they will hold down the fabric while the needles which knit at the main side are being raised by the main stitch cams.

Title: Improvements in and relating to phase measuring circuits for electric oscillations
IPC: G01S3/42
Filed: 1945-07-26
Abstract: 596,478. Phase difference measurements. WYNNE, T. E. July 26, 1945, No. 19226. [Class 37] In a phase-comparing device the oscillations under test are applied to indicating means which supply a thermionic amplifier connected to a feed-back motor controlling the indicating means. In Fig. 1, one of the voltages #, under phase comparison is fed to two sets N. S and E, W of stator windings of phase shift transformer PST, windings W, E, being fed through a 90 degree phase shifting network A. The phase angle of the voltage supplied by rotor R to the grid of valve V2 is a function of the angular setting of R relative to the stator. The second comparison oscillating voltage #2, after amplification in valve VI, is combined with the first in transformers T1, T2. The voltages applied to the grids of valves V3 and V4 are equal only when the grid voltages of valves V1, V2 are in quadrature and are unequal for settings of rotor R introducing any other phase difference. After rectification by diodes V5, V6, the output from valves V3, V4 is applied by control valves V7, V8, to the relay coils 1, 2 which cause relay RL to operate as the phase angle between the grid voltages of valves V1, V2 deviates from quadrature. Operation of relay RL energizes the motor M, which rotates rotor R and effects quadrature phasing of the grid voltages of valves V1 and V2, when relay RL is again rendered inoperative and a pointer connected to the rotor shaft moves over a suitable scale so that its position of rest when the motor circuit is broken indicates the angular difference of phase between the applied oscillations. In a modification resistance-capacity coupling is employed in place of transformers T1 and T2. The indicator may be driven by the rotor R through a suitable coupling so that it does not partake of the hunting movement thereof.
