Title: Electrically heated position adjustment pad
IPC: E01D19/04
Filed: 1973-12-07
Abstract: 1455420 Supporting railway track; structural parts for buildings MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd and JAPANESE NATIONAL RAILWAYS 7 Dec 1973 [13 Dec 1972] 56835/73 Headings E1G and E1W [Also in Divisions F2 H3 and H5] In aligning a beam, girder or rail for example, with a vertical, inclined or horizontal surface, an alignment pad comprising an apertured or cellular thermoplastic sheet 1 and a resistance heating element 5 is interposed between the beam, girder or rail and the surface and the thermoplastic sheet 1 is softened by energising the heating element 5 whilst force is applied to the beam; rail or girder to align it with the surface. When the beam, rail or girder, is aligned the heating element is deenergised and the thermoplastic sheet 1 solidifies to permanently maintain the alignment. As shown the pad comprises two perforated sheets of polyester resin with bevelled edges 3 which are positioned to provide V-notches along opposed edges. Between the sheets 1 is a heating element 5 comprising a fibre glass mat with a sinuous heating wire of copper woven therein. The side edges of the mat are covered with insulating tape and then rolled inwards and bonded to the rest of the mat to form the rolled pack portions 8 which are accommodated in the V-notches. This arrangement provides more heat at the sides of the pad so that the entire pad is more evenly heated opposite ends of the heating wire are passed through insulating tubes 11 to terminals 10 sandwiched between layers 1. The pad is completed by a thermally insulating envelope 9 of polyester resin. The perforations 2 in sheets 1 take up a percentage of the volume of the sheets determined by the estimated reduction in thickness of the pad during alignment. The molten material of the sheets 1 flows into the perforations during alignment. In laying a rail on an uneven base several longitudinally spaced alignment pads are positioned in metal tie plates on the base. Vibration absorbent rubber blocks are placed on top of the pads and finally a rail is placed on top of the blocks. The pads are electrically heated until the rail is correctly aligned either by gravity alone or with the aid of a jack or press. The pads may be used in mounting machinery at a desired level.

Abstract: 1348018 Digital transmission; phase correction of modulated carriers INTERNATIONAL BUSINESS MACHINES CORP 13 Dec 1971 [21 Jan 1971] 57705/71 Heading H4P In a correction arrangement for modulated carrier information signals having phase jitter during transmission in which an output from a carrier extraction circuit demodulates information signals, the latter are delayed by a time value equal to that imposed on the carrier by recovery circuitry so that the phase relation between carrier and information signals is the same. Delay means may be an analogue/delta encoder-shift register-delta/analogue arrangement. The carrier may be reconstituted from a plurality of pilot signals transmitted coincidently with information signals. Sync. signals if provided are taken from the information channel at the delay output and are subjected to narrow band filtering in a switched filter driven by the recovered carrier to obtain a signal for controlling the oscillator. A band stop circuit 13 diverts carrier or pilot signals to recovery circuit 15 and local oscillator 16 which is synchronized from the information signal channel either before or after demodulation. Output S is fed to a demodulator 18 also receiving information signals 3 through delay 17, hence due to such delay the inputs to 18 should be in phase.

Abstract: 594,755. Totalizators. WELLS, R. E. Aug. 28, 1939, No. 24729. [Class 40 (i)] In a totalizator for doubles betting as well as for win and place betting, each ticket-issuing machine comprises two manual selecting switches each associated with a typewheel and controlling central recording apparatus. The indicator board has the indicators arranged in rows and columns, and one selector prepares the circuits of a row of indicators while the other selects a particular circuit of that row. Ticket -issuing machine, Figs. 8, 8a. Selector arms 25, 26 and sets of competitor contacts 23 are mounted on each side of the machine, the arms being secured to type-wheels 29. The type is secured in slots 37 by means of plates 39 and the selector arms are centred on the contacts by spring catches engaging in notches 35. Printing is effected and the control circuits are completed by rotation of shaft 43 by a handle 44. The printing anvil 45 is operated by a cam 47 on the shaft, the type-wheels being locked by pawls 40 lifted into engagement with notches in plates 38 by a cam 148. The control circuits are closed by rotation of a contact member 56 by a friction clutch 41 so that contacts 51-55, Fig. 16, engage a fixed set of contacts 57-61. The member 56 is held in the operated position by a pawl 147, Fig. 8a, and as the shaft 43 returns, a pawl 204 released by the cam 148 engages the clutch member 41 and prevents further operation until the bet is registered. For win and place betting, one of the selector, arms is provided with contacts W, P. Central recording apparatus, Fig. 16. The indicators are of known type having units, tens and hundreds wheels controlled by a solenoid 80, the plunger 87 of which actuates the pawl 100 through a lever 97. A roller 102 on the plunger shifts a pivoted contact 91 into engagement with contact arms 90, 94 for release and alarm purposes. The solenoids 80 of each row of indicators are connected to fixed contacts 78 which are engaged by contacts 77 on a rocking drum 74 when a solenoid 82 is energized. The contacts 77 of the various drums are multiplied to contacts 23 of one selector while the solenoids 82 are connected to contacts 23 of the other selector. Interference between the ticketissuing machines is prevented by groups of double-throw switches such as 140, 141 controlled by pairs of magnets. For four machines, three groups of switches are provided, one 140 controlling the supply of current to the other two. Thus, if a bet is entered on machine A or B, magnet 106 is energized as well as 107 or 122 to supply current to the selector arms of the appropriate machine and so energize the relevant solenoid 80 to register the bet. At the same time, the contact made at 91, 90 operates solenoid 104 to release the holding pawl 147, Fig. 8a, and allow the printing and control mechanism to restore to normal. Contacts 126 of the drum switch 74 hold the operated magnets of the double-throw switches until registration is complete. Further holding circuits are closed over contacts 91, 94 in case the indicator sticks.
