Title: Reinforced plastics film and method and apparatus for making same
IPC: B29C48/10
Filed: 1974-07-24
Abstract: 1466593 Ribbed film; extruder MOBIL OIL CORP 24 July 1974 [26 July 1973 15 Oct 1973] 32727/74 Headings B5A and B5B A reinforced flexible thermoplastic film especially of polyethylene has spaced apart ribs integral with the film wherein each rib comprises a peak defined by the intersection of the surfaces on each side of the rib, the rib surfaces proximate to the surface of the film from which the rib projects being rounded so that the sides of the rib merge smoothly into the film. Preferably the thickness of the film between the ribs a is 0À01-0À05 mm., the rib to rib spacing c is 0À125-2À0 cm., the maximum thickness of the ribs in a direction perpendicular to the plane of the film b is from 1-5 to 10 times the thickness between the ribs a and b is especially 0À1 mm. The ribs may extend on both sides of the film or when peaks are formed on one side only. A slight inner rib will be formed opposite the rib which is extruded. When ribs are extruded on both sides one rib will extend farther from the one side than the other. The film is formed by extrusion through a head having an annular extrusion gap between the die lips which are formed with radially extending peaked notches 22 having rounded corners at their intersection with the annular extrusion surface of the lips to form ribs in the tubular extruded material, expansion of the tube by compressed air and cooling the tube so as to cool first the portions of the film between the ribs and to form a gradually hardening film while the region of the ribs is still plastic with a smooth transition of hardening of the material towards the ribs as the thickness of the material increases towards the peak thickness of the ribs. The dimensions of the notches 22 are such that the ribs as extruded are of lesser thickness relative to the extruded wall thickness than are the ribs relative to the wall thickness of the resulting film.

Title: Improvements relating to railway track circuits
IPC: B61L23/16
Filed: 1947-12-12
Abstract: 650,955. Coded track circuits for railway signalling. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 12, 1947, No. 32836. Convention date, Dec. 17, 1946. [Class 105] A coded. alternating-current track circuit, fed through a feed winding inductively coupled with the track circuit has the feed winding periodically shunted, instead of, as heretofore, being de-energized by a break contact, the supply to the feed winding passing through an impedance arrangement such that when the shunting of the feed winding occurs the impedance of the feed circuit is' increased, so reducing the current taken. Alternating current from a source 3 is applied to the rails through a winding 8 inductively coupled with the usual inductance bond 7, 7a for the return traction current, the winding being tuned to supply frequency by a condenser 10 and fed through the usual limiting resistance 5. The current in the rail is coded by the periodic closure of coding contact 4 which not only shunts current from the winding 8 but de-tunes the feed circuit so that the current later to be broken when contact 4 opens is reduced. A condenser may also be included in the shunting branch, Fig. 3 (not shown), still further to reduce the current through the shunting contact 4 though it should be noted that the winding 8 will then receive and apply some current to the rails but this is kept below the holding value of the track relay.
