Title: Rubber yarn feeding device on circular knitting machines
Inventor: ZAHRADKA PAVEL
IPC: D04B15/50
Filed: 1962-06-12
Abstract: 1,001,027. Knitting-machines. SDRUZENI PODNIKU TEXTILNIKO STROJIRENSTVI. June 12, 1962, No. 22404/62. Heading D1C. In a circular knitting machine including a feeding device for rubber yarn, comprising a rotating disc and a co-operating roller driven by an adjustable friction wheel, the switching in and out of operation of the device is directly controlled by the yarn guide for the rubber yarn. The feeding device comprises a holder 28 pivoted on a fixed column at 32 and carrying a roller 39 drivable by contact with a rubber ring 58 on the periphery of the friction wheel 59. The wheel 59 can be displaced alongs its shaft 60 which is driven by the main shaft of the machine. A spring biases the holder in a clockwise direction towards the roller 39 into contact with the friction wheel. The yarn 66 passes between tension discs 58 before passing between the roller 39 and the disc 44 which is rotably mounted in a lever 45 pivoted to the holder and spring urged towards the roller 39. A rod or cable 26 connects a lug on the holder 28 to the pivoted yarn guide 3 which is urged towards its yarn feeding position II by a spring 6. The guide has an abutment 5 which rides on high, intermediate and low portions 20, 21, 22 of a cam 7 rotatably mounted on a fixed pin 8 of the reciprocable pole frame 9 of the striping device. A pole 14 on the frame is positioned when required by a selector 18 to actuate a ratchet wheel and rotate the cam 7 in steps to cause the abutment 5 to ride on the cam portions 20, 21, 22 in turn the yarn guide moving through the corresponding inactive intermediate and active positions O, I, II. In the inactive position the rod 26 constrains the holder 28 against the action of its biasing spring so that disc 39 is disengaged from the wheel 59. In the intermediate position of the yarn guide the holder is released, the disc 39 is driven and the yarn fed. When the cam 7 rotates to allow the yarn guide to move to its active position the holding and severing device 68 releases the yarn end and the yarn is fed to the needles. On further rotation of the cam at the appropriate time the yarn finger is returned to position O, when the rod 26 again rotates the holder 28 to stop the feeding of the yarn.

Title: Improvements in electromagnetic relays
IPC: H01H51/08
Filed: 1935-08-08
Abstract: 445,403. Electromagnetic and mercury switches. HENDLER, O., 44, Hameaustrasse, Vienna. Aug. 8, 1935, No. 22442. Convention date, June 17. [Class 38 (v)] An electromagnetic relay for two or more lighting circuits has a rotatable member for effecting the switching - over of the circuits which is moved by the displacement of a solenoid core, the rotatable member resting on a bearing in the fitting face of which are inset the contacts of the several circuits, the rotatable member having a recess filled with mercury which opens downwards over its entire length opposite the fitting face of the bearing so that the mercury is free at this opening and on displacement of the rotating member bridges both contacts belonging to the same circuit. As shown in Fig. 1, the solenoid 12 on energization raises the operating core 10 to which is attached a T-shaped operating arm 13. During the subsequent descent of the solenoid core the cross-bar 14 engages a V-shaped depression in an insulating body 1 and rocks it within the bearing block 2. This block has two sets of contacts consisting of pools of mercury 3 in depressions carrying the contact plates 4, 5 and the block 1 has a transverse open slot 6 at its periphery also containing mercury. During the movement of the block 1 the mercury in the slot 6 breaks contact with the mercury in one set of fixed contacts and makes contact with the mercury in the other set. Slots 15 are formed in the fixed body to guide the operating projection 14 during the raising of the core so that it falls in a vertical direction and moves the block 1 in opposite directions after successive energizations of the electromagnet. The block 1 is formed with side recesses 16 leading into the slot 6 so that the mercury is always returned to the recess 6 after the relay has been moved out of its vertical operating position, as during transit. In a modified form, Figs. 5 and 6 (not shown), the pools of mercury corresponding to the fixed contacts are formed in the flat upper surface of an insulating disc while the movable contact member comprises a radial cam with mercury in an open slot in its lower face which is swept over the face of the fixed disc. The radial arm is driven through a clutch from the core of the operating solenoid by a member similar to a twist drill.

Abstract: 1,170,625. Feeding webs. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 28 May, 1968 [15 May, 1967], No. 22468/67. Heading B8R. [Also in Division H2] Steel strip 1 is fed from an uncoiling reel through a processing section 2 to a coiling reel' and rolls 9, 10 are displaceable by drums or winches 9a connected thereto by ropes 12, 13 to control the size of entry and exit loops 3, 4. The drums are adapted to be driven by D.C. motors 14, 15, which are connected in series to a common power source 16 which may be a thyristor controlled converter or a Ward Leonard generator. If the loop 3 is full and the entry section is stopped, strip is fed to the processing section at full speed and roll 9 is pulled towards the now stationary rolls 5, 6. Under these circumstances the motor 14 regenerates power back to the source 16. When the loop 3 is refilled, the motor 14 hauls back the roll 9 to maintain tension in the strip 1. The loop 4 is normally empty and fills at full speed when the exit section is stopped. Dancer rolls (22) may form additional loops between the loops 3, 4, and the section 2, further motors (24) being provided to displace the dancer rolls. These additional motors are connected in series with the motors 14 and 15, Fig. 2 (not shown). Several storage loops may be arranged on either side of the section 2, each loop having a separate tensioning motor. A common source feeds the motors, and contactors for bypassing the motors are controlled to cause sequential loop length changes proceeding from one storage loop to the next.
