Title: Improvements in method of and apparatus for modifying tubular knitted fabric
IPC: D06H7/08
Filed: 1948-03-16
Abstract: 649,932. Finishing fabrics; cutting cylindrical webs. SAMCOE HOLDING CORPORATION. March 16, 1948, No. 7889. Convention date, April 10, 1947. [Classes 31 (i) and 42 (i)] [Also in Groups VII and XVI] Tubular knitted fabric is modified to avoid the helical pattern thereof by advancing the fabric in a flattened state, slitting the fabric at one side to provide separated edges, causing the separated edge of one layer of the fabric to follow an elongated path with reference to the path of the corresponding edge of the opposing layer to bring the design on the separated edges into register in such a manner as to convert the initially helical pattern to a circumferential or non-helical one, and sewing the separated edges so that the fabric is restored to tubular form. As shown, Figs. 1, 2, tubular fabric in flattened condition is fed from a roll 7 by a driven roller 10, passing thence under a jockey roller 13 and over spreaders 22, 23. Roller 13 is carried on an arm 14 which is pivoted at 15 and controls,a variable-speed V- belt drive to roller 10, and serves to maintain the fabric at constant tension, any movement of arm 14 causing a tension-correcting variation of speed of roller 10. The distance apart of spreaders 22, 23 can be adjusted to maintain a desired transverse tension. As the fabric moves over the spreaders, one folded edge is cut by a rotating cutter 39 driven by a motor 37 mounted on two transverse rods 35. The lower layer proceeds horizontally, while the cut edge of the upper layer moves in a loop over rollers 40, 41 extending diagonally over the edge of the fabric on a pivoted support 42 which permits adjustment by means of a knurled wheel 48 to modify the size of the loop so that the two cut edges are brought together again with the pattern (e.g. stripes) at the edges in register in the desired manner. As the separated layers come together the cut edges are uncurled by an endless moving rubber belt 59 of circular section, one rim of which moves outwardly from between the layers, engaging and unrolling the edges which are pressed thereagainst. The edges are then trimmed and sewn together with a whipstitch. The end of spreader 22 is provided with a flattened plate portion 118; as the fabric passes over this portion it is spread vertically so that the operator may observe whether the stripes &c. are properly registered. The fabric is drawn from the spreaders and wound in a roll on a mandrel 30, the roll being driven by a roller 32. Variable-speed belt drives are provided to the various moving parts. In a modified construction, Fig. 8, the fabric is positively drawn over the spreaders by driven belts 121, 128, being nipped between the belts and rollers 125, 132 respectively. In a further modification, the fabric is drawn over a one-piece spreader by nip rollers situated immediately before the wind-up roll.

Filed: 1947-03-25
Abstract: 637,183. Pulse generating and delaying circuits. OXFORD, A. J. H., FISH, N. L. YATES-, and FORSHAW, H. W. March 25, 1947, No. 8107. [Class 40 (vi)] An output pulse is generated under the control of a decreasing and an increasing step waveform. By biassing the decreasing step waveform, a series of output pulses may be obtained. Positive pulses, Fig. 2a applied to Miller integrator valve 4, Fig. 1, cause the anode potential to fall in steps, the output being fed to phase-inverter valve 7. The outputs from cathode and anode are D.C. restored by diodes 13, 12 to give the waveforms, Figs. 2b and 2c. By using a clipper stage (not shown), a pulse may be generated at terminal I corresponding to the first step. The second pulse at terminal II is generated by feeding the anode output of valve 7 through diode 16 to terminal II and the cathode output over biassing resistor R1 and capacitor C1 to diode 17, the resulting waveform appearing as at Fig. 2d. The value of the combination R1, C1 is varied to give outputs at terminals III, IV and V, the output at terminal VI being obtained by clipping waveform, Fig. 2c. At the end of the downward steps, valve 4 is restored by transitron action.

A getter pump comprises two communicating casings 1, 2, casing 1 being connected with the vessel to be evacuated at 5 and casing 2 being connected to a high vacuum pump at 14, means operable to deliver to casing 1 a liquid metal e.g. gallium or gallium alloy getter and to expose the liquid metal getter to gas contained in the first casing while a vacuum is maintained therein by the pump connected at 14 whereby gas is absorbed by the liquid metal getter, means to deliver gas charged liquid metal getter from casing 1 to casing 2, means co-operating with casing 2 to effect degassing of gas charged liquid metal delivered thereto, and means to return the degassed liquid metal getter to the first easing The gallium or gallium alloy is liquid at somewhat above room temperature, e.g. 30‹C. The liquid metal falls as a drizzle from three circular concentric finely perforated pipes 7 on the sloping floor whence it flows via pipe 21 to heat exchanger 20 where it is heated by 600‹C. and then upwardly by pipe 18 to helical channel 16 where coil 25 heats it a further 70‹C. The liquid at 700‹C. is then taken by pipe 19 through the heat exchanger where it is reduced to 100‹C. and then to 30‹C. in cooler 22 after which it is pumped back to pipes 7 through pipe 24. The gas released during the heating is removed by a high vacuum pump connected at 14 and cooling pipes 26 serve to condense metal vapour. A liquid seal is formed by bell 28 and ring 29, bell 28 being secured to angle lever 30 with armature 31 attracted by magnet 32. The bell 28 can thus be opened to produce a high vacuum in 1, 2.
