Abstract: 1,247,313. Pipe couplings. T. D. WILLIAMSON Inc. 6 March, 1970, No. 11005/70. Heading F2G. An apparatus for forming a side opening in a pipeline comprises a housing having a branch connection, with one end sealingly surrounding the pipeline, the housing containing equipment for cutting a portion from the pipeline and for retracting the cut portion into the housing away from the path between the opening and the branch connection. The branch connnection 31 is intermediate the ends of the housing 23 or forms the other end 85 of the housing 81. In the former instance, the cut pipeline portion 32 is retracted into the upper end of the housing 23 above the branch connection 31, by a spring retracted telescopic rod system 42, as shown, or by a rod sliding in an evacuated cylinder on toP of the housing, or an evacuated bellows diaphragm. In the latter instance the cut pipeline portion 32 is retracted into a portion of the housing 81 offset from the branch connection 85 by spring-operated linkages or a spring hinge 87 as shown; alternatively, a ring-shaped portion is cut from the pipeline which is pulled by springs into the bottom of the housing projecting below the pipeline. The pipeline P is cut by a ring charge 39, or ring charges detonated by a fuse 40, and the retraction equipment operates automatically upon completion of the cutting operation. The retraction equipment is attached to the pipeline portion to be cut prior to the cutting operation by means of a threaded stud or studs. The housing is either welded to the pipeline or bolted around the pipeline with a sealing ring surrounding the portion to be out.

Title: Improvements in or relating to radio-navigational systems
IPC: G01S1/02
Filed: 1920-04-23
Abstract: 161,448. Grenfell, G. P., Murray, J. Erskine-, Robinson, J., and Crowther, H. L. April 23, 1920. Bearings, determining.-In a wireless transmitting system for enabling receiving stations to determine their bearings, in which the orientation of the directional radiation is varied uniformly at a given frequency, the transmission is controlled by means operating uniformly at a somewhat different frequency. In one method, a directional loop aerial 3 is rotated, and is energized through a rotating coil 6. If at the commencement there is zero coupling and minimum radiation on a north and south line, and the aerial and coil are rotated through angles of 181‹ and 180‹ per second respectively, the direction of minimum radiation will after one second be 1‹ East. The receiving station determines its bearing by measuring the time interval between a distinctive signal and the first minimum due to coincident minimum radiation and minimum coupling. In a modification, a radiogoniometric transmitting system is used in which the transmission of energy to the aerial is interrupted for a short period of each revolution at a frequency slightly different from the frequency of rotation of the radiator.

Filed: 1958-04-10
Abstract: 855,575. Pipe making. MITTAG, W. April 10, 1958 [April 18, 1957], No. 11371/58. Class 99(2). Corrugated flexible tubing is made by extruding a continuous plastic strip of S-shaped section 3, Fig. 1, helically winding it whilst still hot and subjecting the interlocked convolutions to an all-round axial expansion after which all the wound convolutions are maintained under axial tension until they are cooled. Channel section plastic strip 3 is extruded from a machine 1 through a slack detector 5 and on a channel section feed rail 20, Fig. 4, into the winding head 6 where it is wound on to a rotatably driven mandrel 11 after which it passes over a universal joint 14, Fig. 3, and on to an adjustably inclinable guide shaft 15 which may be telescopic and supported at its end by a spherical bearing or centre 16. The feed rail 20 mates with a slot in a member 23 which is pivotally mounted in the winding head. The member 23 carries a longitudinal guide 26 and a guide roller 27 both of which engage with the open channel of the plastic strip 3 and maintain the side of the channel erect. A second guide roller 30 engages the strip channel after it leaves the member 20 and a helical guide 31, fixed to the bore of the winding head between the first and second guide rollers 27, 30 form the strip into a helical convolution. One or more convolution spacing members 35 and a further axially adjustable guide roller 36, Fig. 9, engage the channel of the formed tube to maintain the shape of the channel and to maintain the convolutions under axial tension. Beyond the member 36 the tube passes over the universal joint 14 and down the inclined guide 15 which passes through cooling means 40, the weight of the tube assisting in maintaining the convolutions under axial tension until they have been cooled. A portion of the mandrel 11 is provided with a fluted portion lying within the winding head to entrain the plastic strip for the first convolution. The slack detector head S e.g. a photoelectric cell device, is connected electrically to a controller 8, Fig. 2 (not shown), which through a shaft controls an infinitely variable speed motor, so that the winding speed of the mandrel 11 driven through a clutch, e.g. on electromagnetic clutch, can be varied in accordance with the extrusion speed.
