Abstract: 1,188,551. Tufting machines, tufted fabrics. D.C. ONE, Ltd. 5 Jan., 1968 [12 Jan., 1967], No. 1653/67. Headings DIG and D1K. A method of patterning cut pile fabric comprises feeding the fabric longitudinally, repeatedly forming in the fabric, at each of a plurality of stations longitudinally spaced apart a laterally-extending row of laterallyspaced cut pile loops, and, at the approach regions to said stations, positively effecting lateral reciprocation of the fabric with substantially the same amplitude of lateral movement at each approach region, whereby a plurality of series of wavy lines of out pile loops are formed in the fabric, the amplitude of lateral movement being greater than the lateral spacing between the cut pile loops so that the wavy lines cross over one another. As shown, a needle bar 2, carrying needles 3, is connected by bars 21 to a needle bar 20 carrying needles 19. The needles 3, 19 have a pitch of 1 inch and are staggered. The needle bars 2, 20 are spaced 5 inches apart. Loopers 10 co-operate with needles 3 to form loops which are cut by knives 12. Loopers 25 cooperate with needles 19 to form loops which are cut by knives 26. Spiked feed rollers 9, 24, arranged respectively ahead of the needles 3 and 19, are reciprocated axially to shift the fabric transversely to the direction of feed through an amplitude of about 5 inches. The arrangement produces two series of wavy parallel lines D, E of tufting which cross one another at C. To accentuate the pattern, every third needle may be omitted. Loopers 10 are carried by a bar 27 and loopers 25 are carried by a bar 30 which is connected by bars 29 to bar 27. The latter is rigid with crank arms 28 on a rocking shaft 11. Knives 12 are carried by a bar 31 rigid with a rocking shaft 13. Knives 26 are carried by a bar 36 rigid with a shaft 35 having a crank arm 34 connected by a link 33 to a crank arm 32 rigid with bar 31. Shafts 11, 13 are interconnected by a linkage, and shaft 13 is oscillated via a linkage from the main shaft. In a modification, shaft 13 is eliminated and link 33 is connected by a linkage to shaft 11 which is oscillated via a linkage from the main shaft. In a further modification the respective needle bars with the associated loopers and knives are operated independently of one another. Alternatively, the two rows of needles may be carried by a single needle bar.

Title: Improvements in or relating to the magnetising of annular magnets
IPC: H01F13/00
Filed: 1939-01-18
Abstract: 523,970. Magnetizing permanent magnets. JURAK, L. Jan. 18, 1939, No. 1719. Convention date, Feb. 16, 1938. [Class 35] An annular magnet with inwardly extending polar projections has the projections progressively magnetized in groups in such a way that two diametrically opposite pairs of adjacent poles are simultaneously magnetized by the two pole-shoes of the magnetizing apparatus, one of these shoes bridging the two similar poles on one side of a diameter of the magnet and the'other shoe bridging the two similar poles (which are dissimilar to the first pair) on the other side of the diameter. In the form shown, the poles 1, 2, 6, 7 are magnetized simultaneously by the poleshoes 12, 13 extending from a U-shaped electromagnet so that the poles 1, 7 have the same polarity which is dissimilar to that of the poles 2, 6. The shoes 12, 13 are then moved through two pole-pitches and the pole pairs 3, 4, 8, 9 are magnetized, this operation being repeated until all poles are magnetized. Where, as shown, the ring has an odd number of pole pairs two of the poles are, in consequence, magnetized twice and to remove the resulting magnetic inequality the entire procedure may be repeated with a diminished magnet saturation.

Title: Improvements in or relating to thermionic valve circuit arrangements
Inventor: WEBB NEVILLE GEORGE
IPC: H03F1/50
Filed: 1957-01-18
Abstract: 842,113. Valve circuits. MARCONI INSTRUMENTS Ltd. Sept. 30, 1957 [Jan. 18, 1957], No. 1932/57. Class 40(6). A valve circuit has the input applied to its control grid 3 an output derived from resistance 15 in its anode circuit and a cathode resistor 9 so that the valve effectively operates as a cathode follower, the suppressor grid being connected to earth through a capacitor and suppressor control grid being connected through high resistances to the cathode the arrangement being such that at least over part of the operating range the anode voltage is in phase with the grid voltage. In the amplifier shown in Fig. 1, resistors 7 and 8 are biasing resistors while resistor 9 is a cathode load so that the cathode voltage varies in phase with the control grid voltage. The suppressor grid is earthed through a capacitor 13 and its voltage accordingly varies effectively out of phase with respect to the cathode so causing the anode voltage to vary in phase with the control grid voltage. Fig. 2 shows a relaxation oscillator circuit similar to Fig. 1 but with a capacitor 18 connected between anode and control grid. At one point in the cycle of operation the suppresser grid voltage is well below that of the cathode so that the anode current is cut off. Capacitor 13 charges through resistor 12 towards the cathode voltage causing the suppresser grid voltage to rise until anode current flows. This causes the anode voltage to fall and thus the control grid and cathode voltage also to fall, thus accelerating the rise of suppresser grid voltage. The cathode voltage continues to fall in this manner until its potential is such that anode and suppresser grid current commence to flow thus discharging capacitor 13. The suppresser potential accordingly falls until it reaches a value where the anode current is caused to decrease. The anode voltage thereupon rises and with it the grid and cathode voltage, so accelerating the relative fall of suppresser grid voltage until the anode current is cut off rapidly by the suppresser grid and the sequence recommences. An output voltage may be taken from the anode or cathode, from a resistance connected in series with the screen grid or from the suppresser grid.

A valve system for controlling fluid flow comprises a main throttle valve 10 having a casing 11 with a straight through flow passage, a transverse recess 14 intersecting the flow passage, a ball 18 mounted in the recess and movable therein by means of an actuator 17 so that its position variably controls the fluid flow through the valve, a control cylinder 16 disposed in line with the recess and having a leaky control piston 20 mounted in it, a seal 27 mounted in a passage between the adjacent ends of the control and the transverse recess, a stem 19 passing through the seal and connected to the control-piston and the actuator, and pipe-lines 32, 35 for supplying and withdrawing fluid from opposite ends of the cylinder in order to control the position of the ball valve. As shown, the pipe 32 is taken from the upstream side of the valve and is connected with the port 28 above the seal 27 and the pipe 35 is connected downstream of the valve with the end of the control cylinder 16 and, via a by-pass, with the pipe 32 ; a pilot valve 47 is positioned in the pipe-line 35. In operation, fluid passes through the pipe 32 via a variable orifice valve 34 into the cylinder 16 and acts upon the piston 20 against the action of a spring 23 to maintain the ball-valve in the open position shown, the fluid leaking past the piston into the pipe-line 35 via the valve 47 which is maintained open by a spring 45. Upon any build-up of pressure at the downstream of the valve, the pressure is communicated through the pipe 35 to a diaphragm 44 in the pilot valve 47 thereby closing the latter; the pressure then increases in the pipe between the valve 47 and the control-cylinder so as to act on the piston 20 and thereby close the ball. valve 10. A variable orifice valve 40 is provided in the by-pass line in order to vary the controlpoint to the pilot valve 47.
