For determining whether the variation in a given time period of the pressure of a fluid in a pipe 1 is above or below a predetermined value, the pipe 1 is connected to a fluid reservoir 2 by a pipe 3 comprising a valve controlled by a solenoid 4, and branch pipes 6a, 6b connect the pipe 3 at opposite sides of the valve to chambers of a differential pressure device. The fluid in reservoir 2 is maintained at constant pressure so that when the pressure in the pipe 1 increases above said constant pressure by a predetermined amount the device 6 closes the contact 16 to energize the relay coil 14. A contact 15 then closes to energize the solenoid 4 for 5 seconds to open the solenoid valve to equalize the pressures in the reservoir 2 and the pipe 1. On returning to its inoperative position the contact 15 momentarily energizes a relay coil 17 to close a contact 18 for one minute. Thus if before the end of such minute the fluid-pressure in the pipe 1 increases sufficiently to cause the device 6 to close the contact 16, a relay coil 19 is energized via the contacts 16, 18 to energize a solenoid 20 to close a valve 21 controlling the flow of fluid through the pipe 1.

Abstract: 586,482. Knitting - machine stop - motions. JENNINGS, H. W. K. (Van Raalte Co., Inc.). June 29, 1944, No. 12416. [Class 74 (ii)] [Also in Group IX] A stop-motion for knitting and like thread or yarn consuming textile machines (see also Group IX) has means for generating an electrostatic field which urges broken or slack threads in. a direction to actuate mechanism which stops the machine, without the interposition of heddles or drop wires. If one of the warp threads 11 of a tricot knitting machine should break, the broken end is attracted by an electrostatic field existing between two insulated conductors 50, 51, and bridges the gap between either of two wires 40, 41 forming one electrode, and a tube 20 forming the other electrode of an open electrical circuit, which, when closed, operates the stopping mechanism. The tube 20 is clothed in a fabric sleeve 21, which is kept wet by a conductive liquid fed through a conduit 23 and holes 22 in the tube. The broken thread is wetted out and made conductive and the stop motion operating circuit is thereby completed. The electrostatic field may be provided by connecting the conductors 50, 51 to the opposed electrodes of an electrostatic induction machine such as a Wimshurst or Toepler-Holtz machine. In a modification, Fig. 3, a rotating hollow roller 82 (e.g., of moulded phenolic-bonded fibre) is charged by the rubbing of a separately driven roller 88 of glass, amber or other material able to generate a charge. The broken thread is wetted by a roller 67 rotated with the roller 82 and coated by a wick 75 with conductive liquid 74 contained in a pan 66. The roller 67 forms one electrode of the stop motion operating circuit and conductors 80, 81 the other. The conductive liquid may be an aqueous solution of a suitable salt (e.g., a chromate). U.S.A. Specification 2,330,212 is referred to.
