Title: Method of and apparatus for forming and cooling a thermoplastic cylindrical tube
IPC: B29C48/10
Filed: 1969-10-17
Abstract: 1,253,393. Extruding thermoplastics tubes and films. PROSYN S.A. 17 Oct., 1969 [22 Oct., 1968], No. 51067/69. Headings B5A and B5B. In the production of thermoplastics tubular material which may be of film thickness, i.e. 0À01-0À25 mm., tubular extrudate 7 from an extrusion head 2 is cooled externally by air delivered from a rotating ring 6 and internally by contact with a cooled mandrel 4, the air from ring 6 being directed to produce a zone of reduced pressure between the annulus of air and the extrudate and upstream of the point where the air contacts the extrudate, the air within chamber 19 being cooled by mandrel 4 to precool the internal surface of the extrudate, and the pressure inside chamber 19 being adjusted in conjunction with the zone of reduced pressure to achieve a required diameter of the extrudate prior to its contact with the mandrel. Ring 6 is adjustable to modify the size of its air outlet. Coolant, e.g. water, is delivered to mandrel 4, Fig. 3, via conduit 14 and removed via conduit 15. Air pressure in chamber 19 is adjusted via ducts 17, 18 and any air carried forward by the extrudate to chamber 20 downstream of mandrel 4 is removed via conduit 13. Mandrel 4, which is axially adjustable, carries a flattening device comprising shoes 22 movable by reciprocation of a piston-like member 25. Downstream of the flattening device are haul-off rolls 9, Fig. 2, and a wind-up spool (not shown). To distribute any irregularities in the product over the width of the spool, rolls 9 are reciprocated or the mandrel and/or extrusion head are rotated. The apparatus is fully automatic being controlled from a panel 11, Fig. 2, and Fig. 1 (not shown), which is shown diagrammatically connected by lines (a-g) to the areas where adjustment may be made.

Abstract: 1,235,228. Oil tankers. PATENTS & DEVELOPMENTS A.S. 17 Oct., 1969 [23 Oct., 1968], No. 51153/69. Heading B7A. [Also in Division F4] In a system for heating a liquid cargo, e.g. oil, in a ship's tank 10, liquid cargo passed upwardly by means of a pump 21 through a discharge conduit 25 is led by way of conduits 26 and 33 into a heat exchanger unit 29, whereafter it passes down a drop line 39 back into the tank. The heat exchanger 37 which can be withdrawn from the outer casing 36 of the unit 29 is fed with heating fluid in the form of steam through a dropline 43 to a reversing chamber 44 from whence the steam flows upwardly through tubes 45 to leave the exchanger by way of outlet chamber 46. The liquid to be heated enters through openings 34 and flows downwardly over the tubes. The liquid cargo can be loaded and unloaded by means of external piping connected to a three way valve 28 located in the flow path between the pump and the heat exchange unit.

Title: Improvements in or relating to pulsed radars
Inventor: NUTTALL THOMAS CAYTON
IPC: G01S13/526
Filed: 1965-12-21
Abstract: 1,131,250. Pulse Doppler radar. MARCONI CO. Ltd. 5 Oct., 1966 [21 Dec., 1965], No. 54180/65. Heading H4D. The Specification describes a pulse Doppler radar wherein cancellation is performed at I.F. This normally requires that the delay of delay means 15 be equal to the pulse interval and equal to an integral number of periods at the I.F. used. The object of the invention is to overcome this latter strenuous accuracy requirement. The transmitted signal at 3000 Mc/s. is produced by mixing the outputs of Stalo 1 and Coho 2 at 2880 Mc/s. and 120 Mc/s. respectively. The echo signals are converted to an I.F. of 120 Mc/s. by mixing in mixer 8 with the output of the Stalo. The I.F. echo signal proceeds directly to one input of cancellation device 9. The output of a pilot oscillator 13 at 22À5 Mc/s. is frequency doubled at 12 and the resultant 45 Mc/s. signal mixed with the output of the Coho, to produce a signal at 75 Mc/s. This is mixed with the I.F. echo signal in mixer 14 to produce a signal at 45 Mc/s. and this signal is fed through the delay means 15 having a delay nominally equal to an integral multiple of a period of 45 Mc/s. The output of the pilot oscillator is also passed through the delay means 15 and is then converted to a 75 Mc/s. signal by means of frequency doubler 17, and mixer 11. The I.F. of 120 Mc/s. is recovered by mixing the 75 Mc/s. signal with the delayed 45 Mc/s. echo signal. Any error in the delay means 15 resulting in phase shifting of the 45 Mc/s. echo signal in excess of an integral multiple of 2 is cancelled by the mixing process in mixer 76, the 75 Mc/s. signal, due to its 22À5 Mc/s. component having passed through the delay means, having a phase slight equal but opposite to said excess. The delayed I.F. echo signal is passed to the cancellation device 9, the output of which is coherently phase detected.
