Title: Improvements in or relating to snap action electric switches
IPC: H01H19/32
Filed: 1944-02-12
Abstract: 575,338. Snap-action switches. MORRISON, P. H., TAYLOR, S. W., WOOD, R. S., and PLESSEY CO., Ltd. Feb. 12, 1944, No. 2624. [Class 38 (v)] A switch operates with a snap-action when the release of a catch allows movement by a spring which is torsioned from each end alternately with successive movements of the handle. The switch body comprises two cup shaped members 1, 2 bolted together to hold in position fixed contacts 3 which fit into pairs of slots half in each of members 1, 2. Moving contacts 29 made of a number of arcuate laminations, fit into slots 28, cut in insulating rotor 23, and are pressed outwards by springs 30 with slotted ends to give each lamination separate pressure. Rotor 23 surrounds a spindle 14 journalled in recess 13 in cup 2 at one end and in bush 5 at the other. Packing rings 18 and 7 in spindle grooves 17 and surrounding bush 5 respectively seal the switch. The rotor is mounted on a boss on a catch plate 21, and both would be free to rotate independently but for the engagement of body projections 10a and 10 in recess 23b in the rotor and with catch plate 21 respectively and for the engagement of rotor projection 23a with lobe 12 on a leaf spring 11. Relative movement between the rotor and catchplate due to the stressed helical spring 24 in the cylindrical space between rotor and spindle, which has ends engaging respectively a lug 25 on the rotor and a hole in the catchplate is prevented by the catchplate engaging rotor abutment 22. Keyed to the spindle at the opposite ends of the switch are sector plate 21 and cam plate 26. To operate the switch from the position shown, spindle 14 is rotated in a counter-clockwise direction by a handle (not shown). The sector plate 20 moves the catchplate 21 and winds up the spring 24 the other end of which cannot move until one of two lugs 27 on the camplate 26 engages and pushes back lobe 12 and spring and rotor snap round as far as projection 10a allows. When the spindle is turned in a clockwise direction, a lug 26a on camplate 26 engages the end of the spring which is wound up against catchplate and rotor until the second ear 27 of the camplate pushes back lobe 12 to release the rotor with a snap.

Title: Circuit arrangement for controlling means for measuring the speed and rolling resistance of railway cars
IPC: B61L17/00
Filed: 1957-01-30
Abstract: 815,018. Railway car retarders. WESTING- HOUSE AIR BRAKE CO. Jan. 30,1957 [Feb. 14, 1956], No. 3247/57. Class 103 (1). The track leading from the hump to the retarder bars of a railway classification yard includes a section AT followed by a section BT, the sections being preferably of about 60 feet and 10 feet in length. A car moving down from the hump in the direction of the arrow shown, on entering section AT, operates occupancy relay ATR, which is de-energized. Closure by relay BTP of contact 19 energizes the units RSM, a radar speed measuring apparatus, and RRC a rolling resistance computer. As the car moves through the section AT, the unit RSM is fed by signals received by an antenna RA and the rolling resistance is computed by the unit RRC for transmission to register relays R1, R2, &c., for transmission to storage banks in a manner similar to that described in Specification 781,845. The storage transfer relay ST is energized as soon as the car enters the second track section BT and energizes the relay BTR so as to also energize relay ST through a circuit including contacts 25, 26 and 27, the contact 26 closing only when the initial storage bank is free of any previous storage. The retarder system thus provides a control circuit arrangement for rolling resistance measurement apparatus for railway cars which delays the final registration of the measured rolling resistance until the averaging of the variable factors is accomplished, but at the same time allows the initiation of the rolling resistance of a following car, while the measurement for a first car is still being transferred to a bank of storage relays.

Abstract: 1168522 Super-conducting material GULF GENERAL ATOMIC Inc 23 Jan 1967 [28 Jan 1966] 3265/67 Headings H1A A5 and A4D A composite super-conducting material comprises layers less than 1Á thick of a material which super-conducts at a particular temperature e.g. Nb 3 Sn, alternated with layers of a material which does not superconduct at that temperature, e.g. a metal such as Nb, Cu or Ag, or an insulator such as a silicon or aluminium composite or an organic compound, the thickness of the latter layers being at most 20% of that of the former layers. In the preferred form Nb 3 Sn layers are separated by layers of Nb. A method is described in which Nb and Sn are vacuum deposited from heated crucibles 21 on to a heated stainless steel substrate sheet 41. Electron heating is used to evaporate the material from the crucibles 21. The relative deposition rates are adjusted to cause Nb 3 Sn to be deposited, and at regular intervals a shutter 55 intervenes between the Sn source and the substrate 41, so that a layer of Nb alone is deposited. A laminated structure thus builds up, and when it is sufficiently thick the shutter 56 may interrupt the flow of Nb vapour to allow a protective layer of Sn to be deposited. An insulating coating may or may not then be applied over the Sn layer. The composite super-conductor, which is flexible, may either be left in contact with the substrate 41, or may be separated therefrom. An alternative method is referred to in which the substrate 41 is reciprocated back and forth over two separate baffles through which Nb3Sn and Nb are deposited independently. Alternative deposition techniques are flame spraying, sputtering or chemical deposition.
