Title: Improvements in electric feeder connectors for contact rails on electric railways
IPC: B60M1/30
Filed: 1921-12-09
Abstract: 194,005. Hunter, P. V., Mather, J., and Callender's Cable & Construction Co., Ltd. Dec. 9, 1921. Couplings. - Feeders are connected to contact rails of electric railways by means supporting them on the rail but not passing through the rail itself. The device may thus move axially on the rail when necessary. In one construction, Figs. 1 and 2, the cable lug g is secured to two members b, d by a bolt f. The member b extends 'beneath the rail and engages the inner side of the flange by claws c formed on it while the member d rests on the rail and completes the supporting means. The electrical connection is made by bonding members h connected to a lugplate j bolted to the connector plate b. In a modification, the members b, d are arranged as shown in Fig. 4.

Abstract: 1394343 Pre-heating extrudable material NORDENIA KUNSTSTOFFE PETER MAGER KG 11 July 1973 [17 July 1972] 33124/73 Heading B5A Plastics material 3 contained in the hopper 5 of an extruder 2, extruding a film or sheet 7, is pre-heated by air circulated through the hopper 5 and which comprises cold air mixed with air heated by heat produced from heating elements 4 of the extruder. In the Fig. 1 embodiment, the heated air is drawn by a fan 10 from a hood 8 surrounding the extruder 4, and delivered through the material in the hopper via an inlet 11 and an outlet 12 from which the colder air may then be employed in thermal conditioning of the room containing the extruder. The temperature of the air entering the hopper is maintained constant, e.g. at 60 C., by admitting the cold air at a further inlet (not shown) to the fan 10, the quantity of which air is regulated by a throttle flap valve. In the Fig. 2 embodiment (not shown) a water cooling coil (14) extends intermediate the extruder heating elements, and as a coil (16) of a heat exchanger (15) through which air is drawn by a fan (18) to be similarly circulated, with similar provision being made for the admission of cold air to maintain a constant temperature. The amount of air conveyed through the hopper may additionally be regulated by driving the fan at a variable speed, e.g. through a D.C. motor, or a three phase motor with reversible poles.

Abstract: 889,498. Cold separation of air. UNION CARBIDE CORPORATION. Oct. 7, 1959 [Oct. 13, 1958], No. 33921/59. Class 8(2). Periodic actuation of valves 22, 23 Fig. 2 , serving to direct warm air containing condensible impurities from an inlet 10 through one or other of alternating cold accumulators N1 N2 and of valves 24, 25 to direct a reverse flow of cold separated constituent e.g., nitrogen from a duct 16 through the accumulator being dermied is effected in response to-the continuous detection of a predetermined temperature difference between corresponding thermal levels intermediate the warm and cold ends of the accumulators. To initiate a cycle a gas thermometer 30 within the air accumulator N1 and registering -75‹C. assists a thermometer 31 in accumulator N2 at -100‹C. to expand and contract bellows 33, 34 respectively and so move a single-pole doublethrow switch 39 to break a contact 60 and make a contact 61 thereby allowing current to pass from mains 40 through a coil 45 resulting in relay contacts 46, 47 being moved from the position shown to their open and closed positions respectively which in turn results in air valve 23 and nitrogen valve 24 being opened andair valve 22 and nitrogen valve 25 being closed. Air outlet conduits 13, 14, 15 at the cold end of the accumulators have non-return check valves therein as have nitrogen inlet ducts 16, 17, 18. In a modification the temperature-responsive means comprises amines of a wheatstone bridge ; the unbalance current at the predetermined temperature difference being sufficient to operate the switch pole. In a further modification accumulators M3, N4 Fig. 7, one of the branched flow type wherein warm air enters opposite ends of the on stream accumulator through valves 439, 438, 427a, 428a or 445, 446, 427b, 428b and leave at the mid-point through a duct 406.
