Title: Improvements in or relating to substitution arrangements for stand-by equipment in signal transmission systems
IPC: H03F1/54
Filed: 1957-03-19
Abstract: 829,348. Telephone transmission systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 19, 1957 [March 22, 1956], No. 8977/57. Class 40 (4). [Also in Group XL (c)] In an arrangement comprising two switching relays for switching in alternative transmission equipments, each switching relay has an auxiliary relay which in its unoperated state short-circuits its associated switching relay and in its operated state short-circuits the other auxiliary relay. As shown, Fig. 1, switching relays A and B serve to connect the carrier sources 1, 5 to the common circuit 4 and when unoperated to respective dummy loads 8, 12. Fig. 2 illustrates the timing of events, the broad end of an arrow denoting the closure of a front contact and the pointed end the closure of a back contact. Assume first that relays C and A are operated (the contacts of these relays are shown in the operated position) so that carrier source 1 is in use. To bring carrier source 5 into use switch 17 is operated short-circuiting C which opens its make contact c1 at time t2 thereby initiating the operation of relay D. When D opens its back contact d2 at time t8 it initiates the operation of relay B. When at time t3 C makes its back contact c2 it initiates the release of relay A. The interval between the making of the front contact b1 of B and the breaking of the front contact a1 of A (which is the time for which the supply to load 4 is interrupted) is seen to be t7-t4 which can be made very small by adjusting the operate and release times of relays A and B, which may be effected by adjusting resistances 9, 10, 13, 14. Change-over may be effected automatically on failure of the carrier supply in use. Thus, if carrier supply 1 is in use, when it fails relay E falls back, to open the circuit for C to initiate the change-over as previously described, and also to complete a circuit for the alarm 23.

Title: Improvements in and relating to pulling over machines for use in the manufacture of boots and shoes
IPC: A43D23/00
Filed: 1923-04-03
Abstract: 221,238. Pochin, F. H., Pochin, H. S., and Bromley, J. H. April 3, 1923. Pulling-over.-Relates to improvements in the machine described in Specification 3301/10, particularly as modified by the invention described in Specification 159,687, and consists in the provision of additional mechanism whereby (1), connections are provided between the jack-operating treadle and the treadles operating the pincers so that only the first treadle need be manipulated, and (2), adjustment of the machine for a smaller last does not increase the opening of the pincer jaws. Rocking levers 8, 9, Fig. 2, act on the treadle levers for the side and toe pincers, as described in Specification 159,687, but their outer ends rest on a block 7 with an inclined lower surface supported by a wedge 3. The cam 1 stops at the end of the machine's cycle in a, definite angular position, and this position is adjustable, as described in Specification 3301/10 to set the pincers for the size of last next to be operated on. To cause the pincers opening to correspond with this adjustment, the cam 1 is provided with a cam surface 4<a> actuating a lever 2 linked to the wedge 3. Another cam surface 4 on the cam 1 actuates a lever 5 connected bv a link 11 to a spring 12 which tends to pull the block 7 from under the ends of the levers 8, 9. The treadle lever 13, Fig. 3, is provided with a finger 14 to engage a pivoted extension 15 of a lever 16 provided with a T head 17<a> adapted to engage the heads of plungers 18, 19. These plungers normally prevent the block 7 from moving under the pull of the spring 12. As the treadle lever 13 is depressed the plunger 18 is first retracted, allowing the block 7 to move from beneath the end of the rocking lever 8, and the toe-pincers to close. Further movement of the lever 13 withdraws the plunger 19 and allows the side pincers to close. Further movement of the treadle elevates the last to stretch the upper, and the operation proceeds as described in Specification 3301/10.

Filed: 1941-07-23
Abstract: 545,562. Duplicating machines. FORD, F. R. July 23, 1941, No. 9289. Addition to 538,163. [Class 100 (ii)] Modifications in the duplicating machine described in the parent Specification comprise (1) operatively connecting each pressure roller to its corresponding moistening pad so that they move into and out of operation simultaneously. Each pressure roller 39, Figs. 2 and 3 is carried by a stem 38 slidable in a box 35 and raised to the inoperative position by a spring 52 connected to a lug 50 on the stem, and depressed into the operative position by a rotatable cam 46 acting through a press stud 42 and spring 44. The cam 46 is turned by a finger lever 47 fixed to its shaft 45 and is connected to one end of a Bowden wire 72 the other end of which is conuected to a block 70 on the rod 69 carrying the moistening pad 55. When the cam is turned to allow the spring 52 to raise the roller 39, the wire 72 withdraws the pad against the action of a returning spring 78. (2) The operating levers 47 of the pressure rollers may be normally connected by a disconnectible link so that as one roller is depressed to operative position the other roller is raised into the inoperative position. (3) The carriage supporting the pressure rollers and moistening pads is in two parts connected by a pivot shaft 30 so that one part, 31, may be raised to give ready access to the parts carried thereby and to the printing cylinder 10. (4) The bar or roller 61 for pressing the copy sheet 54 on to the pad 55 is carried by one end of levers 9 pivoted at 56 to the carriage part 31, the other ends of the levers 9 being connected by a bar 57 pressed by a spring 64 into contact with adjustable stops 58 carried by the lugs 50 on the stems 38. The depression 16 in the cylinder 10 which is provided to facilitate the insertion of the copy sheets is formed as a cam adapted, when the cylinder is rotated, to raise the roller 39 and compress the spring 44 so that the roller is resiliently pressed against the cylinder 10 during the printing operation. (5) A stop 79, Figs. 2 and 5 against which the spring 78 abuts and which limits the movement of the pad into the inoperative position, is provided with a number of angular slots to accommodate the rods 69 and is fixed to a rod 80 having an operating handle portion. By moving the rod 80 axially, the stop may be moved clear of a stop pin 82 and then turned upwardly to allow of complete removal of the pads 61. The pads are slidable between guide bars laterally adjustable on the tank 19 and the casings 66 of the pads have portions 67 which, when the pads are moved into the inoperative position, are interposed between the pads and their supply wicks 68 to cut off the supply of fluid to the pads. A finger lever 90 by which the carriage carrying the pads and rollers 39 is advanced step by step across the machine, is adapted to be operated automatically by the engagement with the lever of the end 96 of a lever 92 pivoted at 93 and carrying a roller in the path of a cam 91 on the end of the cylinder 10.
