Title: Improvements in or relating to circular knitting machines and to knitted fabrics produced on the same
IPC: D04B15/00
Filed: 1965-10-18
Abstract: 1,136,381. Knitting. J. C. DOUGHTY. 18 Oct., 1966 [18 Oct., 1965], No. 44093/65. Headings D1C and D1K. Groups of needles 9, 28, Figs. 1 and 2, are mounted in needle blocks 6, 22 within or outside the needle cylinder or cylinders or cylinder and dial of a circular machine, the blocks being mounted on rings 14, 29 which are movable to circumferentially adjust the needles in the blocks relatively to the needles of the main bed or beds. Cam blocks 11, 24 connected to the cam boxes of the machine move across the blocks to operate the needles 9, 28. Consequently a knitted structure is superimposed on one, either or both faces of a plain, rib, or purl fabric and consists of groups of needle wales which can run parallel to the wales of the main fabric or extend in an inclined direction across the main fabric, Figs. 13, 14 and 18, or groups of wales within the superimposed group may cross each other to effect a cable stitch pattern, Figs. 15 and 19. The superimposed structure may be further patterned by, for example, tuck work. In addition, the superimposed structure may comprise an appendage which is secured along one edge only of the main fabric, Figs. 17 and 20. Interlocks 53, Fig. 4, may be provided associated with each selector jack beneath the needle in the cylinder of a circular machine. The interlocks are actuated by the operative needles in the blocks and serve to retract the jacks to ensure that the corresponding cylinder needles are not operated simultaneously with the needles in the blocks. In an alternative arrangement for producing the cable stitch arrangement the blocks 64, 65 Fig. 5, are capable of being raised from a low operative position, in which their needles cooperate with the machine needles, to an horizontal position in which they are inoperative. In either position the blocks can be shogged relative to each other so that their stitches cross to produce cable stitch effects. The needles in the blocks can be coupled to repeater elements in an adjacent block. The needles and elements are coupled in a reverse sequence such that the needles are caused to operate first sequentially in one direction and then sequentially in the opposite direction. A separate yarn guide is provided and oscillates about the needles of the block such that a superimposed structure is achieved by reciprocating knitting. If the end needle or needles only of the group take the main yarn the effect is to produce an appendage produced by reciprocating knitting and secured to the base fabric along one edge.

Abstract: 1,270,320. Measuring liquid density. BYRON JACKSON Inc. Sept. 11, 1969 [Oct. 4, 1968], No.45005/69. Heading G1S. A fluid whose density is to be measured is circulated through a U tube 21 pivoted on hinges 27, Figs. 1, 2, and provided with flexible seals and couplings 34. An actuator 39 adjustably movable on a base rail 15, Fig. 3, counterbalances the unladen weight of the U tube, and a second device in the form of a load cell 41, Fig. 4, is a force balance mechanism that restores the U tube to its neutral position V provides a signal that is related to the variations in the weight of the tube V the density of the liquid therein. The actuator 39, Fig. 3, has an oil filled bellows 48 provided with a damping spring which exerts a force on an arm 58 and the U tube 21 when air-pressure is applied to the surface of oil in a reservoir 44. The air is supplied via a conduit 46 and pressure regulators 112, 118, Fig. 1, so that the oil in the reservoir 44 and bellows 48 is pressurized via oil filled ducts 62, 63, 64. The actuator is initially set and zeroized so that the empty U tube is counterbalanced with a tang portion 119, Fig. 2, positioned midway between a pad 123 and a movable conical locking head 126. The load cell 41, Fig. 4 which is also movable along the rail 15, has an air supply conduit 77 and an air line 84 leading to an airpressure gauge 116. The air-pressure in the chamber 82 registered by the gauge 116 is proportional to the density of the liquid flowing in the U tube. Variation of the density of the liquid being measured causes movement of a piston 85 attached to the U tube and movement of a dumb-bell shaped valve 105. This valve controls the supply of air to the signal line 84 via conduit 77 and may also allow the air in chamber 82 to escape through ducts 94, 95 to the atmosphere. Eventually the piston 85 is restored to its neutral position and the resultant pressure in the chamber 82 registered as a density on the gauge 116.

Abstract: 1,222,613. Supply circuits for resistance welding apparatus. PRESSED STEEL FISHER Ltd. 22 Oct., 1969 [23 Sept., 1968], No. 45158/68. Heading H2H. Welding current is supplied by way of a pair of anti-parallel ignitrons whose firing paths include a common thyristor. The circuit includes a memory device which stores energy during one half-cycle to trigger the thyristor in the next half-cycle. In the arrangement shown, the primary winding 38 of a welding transformer is connected in series with anti-parallel ignitrons 11 12 across a mains supply. The firing paths for the ignitrons include diodes 13, 14, 18, 19 and a common portion comprising a thyristor 15 in series with a Zener diode 16 and a resistor 17. The firing path for ignitron 11 also includes a weld relay 36. A first triggering circuit comprises a transformer 20 and delivers a pulse to the thyristor when a device 37 breaks down, so that the thyristor 15 is fired at a predetermined phase angle during alternate half-cycles when ignitron 11 is of the correct polarity, provided the relay 36 is closed. At the same time, a transformer 28, in parallel with the welding transformer 38, is energized and a capacitor 32 in a second triggering circuit is charged. In the subsequent half-cycle, this capacitor discharges through resistors 33, 34 and diode 35 to fire the thyristor and thus energize the second ignitron 12.
