Title: Sheating elongate bodies
IPC: B29C48/06
Filed: 1974-03-07
Abstract: 1450313 Repairing cable sheaths INDUSTRIE PIRELLI SpA 7 March 1974 [23 March 1973] 10363/74 Heading B5A [Also in Division H2] A tubular insulation sheath of polyethylene is extruded around a zone of an electric telephone or power cable between spaced apart locations at which the cable is clamped, the extrusion being effected from the tubular orifice of a die which is mounted to an extruder for displacement along the zone during the extrusion. The die is axially divided to permit it to be manually assembled around the zone of the cable and, during extrusion, vacuum is applied through the die to between the sheath and cable. The sheath may be extruded during the manufacture of the cable, or in repairing damage to the insulation of part of the length of a submarine cable raised from the sea bed on to a cable laying ship. Movement of the die and the extruder along the zone is effected on a wheeled carriage Fig. 1 (not shown). The die, Fig. 3, comprises respective axially divided pairs of inner and outer shells 11, 12 which locate together, at an annular groove and projection 13, upon manual assembly by handles 19 around the cable 2 which passes, at a centering ring 20, through a bore of the die to which the vacuum is applied at an inlet 21 during extrusion. The assembled die is manually inserted, and secured, within an extruder die head 6, Fig. 2, at a recess 22 having a lateral opening 22<SP>1</SP> through which the cable is introduced prior to its clamping at the spaced apart locations. During extrusion, the insulation is delivered to diametrically opposed inlets 17 of the die, supplying an annular die groove 16, by a pair of die block passages 18 supplied from the extruder 4, via a valve 24 which, at the termination of extrusion, is operable to divert the insulation to the exterior of the block 6 at 25.

Abstract: 1,095,834. Pipe couplings. J. MULLER. March 11, 1965 [Aug. 20, 1964; Oct. 29, 1964], No. 10371/65. Heading F2G. [Also in Divisions F1 and G1] A pipe coupling 1 as disclosed in Specification 873,671 comprises a valve 7 which is spring loaded into its closed position by a spring 13 and eccentric cam 8 combination and is opened by rotation of the cam by means of a handle 10 and coupling means including catch rings 4 and a grip ring 5. The other half of the coupling is identical with that shown, such that the group rings 5, when rotated with the halves of the couplings in abutment, cause ramps integral with the ring 5 of one of the halves to engage the catch rings 4 of the other half. With the halves coupled the valves are opened and a sector 11 of each eccentric operating handle 10 co-operates with an abutment of the grip ring 5 such that the valves have to be closed before the coupling is disconnected. A visual flow indicating device is connected to the coupling as by screwing or welding or the body of the device may be integral with the body of the coupling. The device includes a rotatably mounted paddle wheel 18 which is magnetically coupled to a visible pointer or disc 23. In a further embodiment the device is as disclosed in Specification 988,282 and comprises an oscillating disc which rotates a magnet through a crank arrangement, the magnet being magnetically coupled to a pointer (Figs. 4, 5, not shown). The magnetic coupling may be used to form eddy currents in a ferrous metal disc which is attached to a spring-loaded pointer (Figs. 6, 7, not shown). Also a flap valve may be magnetically coupled to a pointer directly or through toothed gearing (Figs. 8, 9, not shown). This valve may be constructed such that it closes about its centreline (Fig. 10, not shown).

Abstract: 1375904 Electron beam apparatus FORD MOTOR CO Ltd 6 March 1972 [12 April 1971] 10389/72 Heading H1D Electron beam generating apparatus comprises a plurality of thermionic cathodes 12, Fig. 1, arranged within an evacuated envelope 10, a reflecting electrode 22 for reflecting emitted electrons and for collecting positive ions, an anode 24 for attracting the electrons, and a magnetic field for focusing the electrons into a beam. There may be eight cathodes equally spaced round the circumference of the envelope, and each may comprise a directly heated filament 40 parallel to the beam axis. The anode 24 may be covered by an electron permeable window 34 through which the electrons pass to an external anode 32 which may comprise a surface which is to be bombarded or irradiated by electrons. The magnetic field sould increase in strength towards the anode 24, and for this reason the number of turns in the focusing coils 42-48 may increase progressively. The coils may be connected in series or in parallel, or may be individually energized.
