Title: Improvements in or relating to Apparatus for Producing Perforated Strip by Electrical Current Impulses.
IPC: H04L15/32
Filed: 1916-11-18
Abstract: 112,141. Harrison, H. H., and Creed & Co. Nov. 18, 1916. Receiving systems; strip-perforating receivers; synchronous movements.-In systems in which the received impulses perforate a travelling strip fed synchronously with the current reversals, the driving-motor M, preferably of the phonic wheel type, is controlled by a reed R having a definite rate of vibration which is controlled by a. magnet RM in circuit with the tongue of a correcting- relay CR. The relay CR is arranged in series with the tongue of the line relay LR, the punchselecting magnets PM<1>, PM<2>, a divided battery B<1>, B<2>, and a condenser C. The motor M is driven by the battery MB and contacts c<2>, c<3> in known manner. Springs S are arranged to limit the travel of the reed R. The circuit of the reed magnet RM includes a contact x<2> engaged by the reed and contacts x, x<1> of the relay CR. The reed is arranged to run slightly fast, but during synchronous running, the tongue w in passing from one contact to the other momentarily breaks the circuit of the reed magnet RM and the reed consequently vibrates at a slightly lower rate than the normal, thus slowing down the motor M. This effect can be varied by adjusting the contacts x, x<1>, thus altering the transit time of the tongue w. The perforation of the signal holes is effected directly by the punching magnets PM<1>, PM<2>, and the feed of the strip is effected by cams or other mechanism driven by the motor M.

Class 78 (5) A load limiting device for a crane comprises two members having a uni-directional driving connection between them mounted on a support, means for attaching one or more hoisting ropes of the crane to the first member, a friction brake between the second member and support resisting rotation of the second member relative to the support, restoring spring means between the first member and the support resisting rotation of the first member relative to the support and trip means effective upon rotation of the two members relative to the support for interrupting the supply of power to the hoisting mechanism of the crane. A pair of supports 2 pivoted at 39 to the crane support a shaft 4 to which are 'keyed plates 5 and 8 the plate 5 being bolted to the support and a hollow drum 10 holding the hoisting cable surrounds the plates. A plate 14 is mounted between the plates 5 and 8 to be freely rotatable on the shaft, the periphery of the plate has shaped recesses for balls 21 urged by springs to contract the drum for uni-directional drive between the drum and plate. The drive may otherwise be effected by ratchet and pawls. One or two brake linings 15 are secured to the plate 14. The plate 8 is urged into contact with the brake lining by a spring 16 on the shaft adjustably controlled by a nut 17. A spring 25 is anchored on the drum and the plate 8. The drum has a part 11 for the cable and a part 12 having a flat portion 13 for a roller 37, vertical movement of the roller controls the motor switch or other control means. The drum is held stationary by the brake and spring 25, when these are exceeded by the load relative movement between the drum and plate 14 takes place consequently raising the roller 37 from the flat part 13 and releasing the control means. A stop 28 on the drum normally engages a cross bar 3, this stop is elongated or an extra stop is provided on the support to limit the rotation of the drum and so prevent re-engagement of the roller with the flat part. Specification 551,193 is referred to.
