Title: Improvements relating to plastics sheathed pipes having end-protecting plugs
IPC: B65D59/02
Filed: 1969-09-25
Abstract: 1279832 Stoppers for pipes and tubes BENTELER-WERKE AG 25 Sept 1969 [26 Nov 1968] 47318/69 Heading F2P [Also in Division B8] The end of a metal pipe is provided with a removable plug to protect the pipe from fouling, corrosion and other damage, the plug being in the form of a thimble with a flanged rim which covers the end face of the pipe, being forced into the end of the pipe, and being retained in position by a peripheral inward constriction of a plastics sheath applied to the pipe which embraces the face of the flanged rim of the plug. In the embodiment shown, drawn steel tubes 1, 2 are closed by plastics plugs 4 comprising a tapered cylindrical shell 4<SP>1</SP>, a thinner bottom 5 and a flanged rim 6 which has the same outside diameter as the pipes. Double-ended steel connecting members 7, with an axial channel 8, connect pairs of tubes 1, 2, and hold them in axial alignment. The tubes are then passed through the nozzle head of an extruder, which coats them with a plastics sheath 3 which also covers the connecting member 7 and follows its contours, forming external groove 16 and internal constrictions 14 and 15. The elevated temperature of the extrusion process causes the plug and the sheath to fuse together, thus ensuring a tight seal and retention of the plug. The bottom of the plug is of reduced thickness to facilitate distortion due to pressure changes caused by the elevated temperature of the extruder. Channel 8 in the connector 7 equalizes the pressure within adjacent plugs and so reduces the pressure changes. The pipes are separated by a cut at the groove 16 and protected by their plugs during transportation and/or storage. When they are required for use the sheath 3 is cut near the end (at 17, Fig. 3, not shown), and peeled off the pipe end, and the plug 4 extracted by means of a suitable tool, giving a pipe with clean ends and a plastic sheath which may provide sound and heat insulation.

Title: Television vertical blanking pulse generators
Inventor: ELLIS RICHARD JOHN GODWIN
IPC: H04N5/08
Filed: 1968-10-10
Abstract: 1,247,694. Television. PYE Ltd. 8 Oct., 1969 [10 Oct., 1968], No. 48055/68. Heading H4F. In a PAL system wherein the swinging colour bursts are required to be suppressed during the transmission of the vertical synchronizing signals and the associated equalizing pulses, and wherein the initial and final bursts in each and every field are of identical phase, e.g. as described in Specification 1,151,726, the blanking pulse should last for nine line periods and the leading edge should vary in position relative to the field datum point over a four field cycle as indicated at X-X in Fig. 1. The plots 1.1 to 1.4 each show 3 line sync. pulses, 5 equalizing pulses at double line frequency preceding and following 5 broad pulses comprising the vertical sync. signal, and finally two line sync. pulses, the phases of the colour bursts being indicated by the arrows. Fig. 2 shows a suitable circuit for generating the blanking pulse. A signal 2H of twice line frequency is divided at 1 and 3 and employed to trigger horizontal and a vertical sync. pulse generators H and V. A further division at 2 produces the colour axis gate waveform H/2, e.g. as shown in Figs. 1.5 to 1.8 and 3.2, which also varies in relative phase over a four field cycle and controls the phase of the colour burst according to whether it is positive or negative. The negative going edges of the waveform 3.2 actuate a generator 6 to produce 10 Á sec. negative pulses 3.5 which are fed to an AND gate 7. An AND gate 4 in conjunction with the divider 3 produces a pulse 3.3 commencing at the 616th input pulse which enables a generator 5 to produce a pulse 3.4, lasting for between 2 and 2¢ line periods, typically 140 Ásec., and longer than pulse 3.3, which is fed to the gate 7. The output of gate 7, 3.6 to 3.9, causes a generator 8 to produce a blanking pulse of 9 line periods duration. Reference has been directed by the Comptroller to Specification 1,151,726.
