Clamps 9 comprise a cleat screwed to a linked plate of the endless conveyer the clamp jaws being slidable along a vertical slide (Figs. 4, 7, not shown). The jaws have stops which prevent overlapping and which engage an actuating means associated with rotor 1 to become prised apart as it rotates. Vacuum tubes are supplied to the clamps along a shoot. As described two of the rotors, namely 2 and 6 are drive rotors being connected to an electric motor (Fig. 6, not shown). Each rotor, as exemplified in Fig. 8 by rotor 2, comprises sprocket discs 69, 70 on shaft 36 rotating in relation to spindle 75, and arranged between housing plates 61, 62. The actuating mechanisms comprise profiled annular members 80, 81 fixed in relation to plates 62, 61. As shown their height varies in a regular manner, whereby on the right hand side the clamp 9 has been lowered by engagement with member 81 into engagement with shaping mechanism 79 (detailed in Fig. 9, not shown) raised by member 80, disengagement following on further rotation of the sprockets. The rotors are arranged to give a zig-zag path to conveyer 7, and rotor 6 is associated with a tensioning means. After rotor 6, the bases are released from clamps 9 and transferred via clamps 34 on assembly 32 to assembly 33 for further processing.

A method of detecting leaks in a pipe-line comprises flowing oil through the line, injecting into the flowing liquid a dilute solution of an oilsoluble radio-active material to form a radioactive slug in the line, flowing the slug through the line and leaking portions of it into the adjoining ground, thereafter continuing to flow additional amounts of the oil behind the slug to flush radioactive material from the interior surface of the line, introducing and passing a radio-activity detector and recording means through the line to record with distance along the line radio-activity exterior of the line, removing the detection and recording means, passing the radio-active slug into a storage vessel wherein it is mixed with oil and retained until the radio-activity of the mixture has dropped to a safe level. The oil may be a petroleum oil or an oil-soluble organic compound and the radioactive material may be an organic derivative of bromine 82 or iodine 131 at a concentration of 0. C1 to 1%. The pipe-line pig incorporates an instrument carrier wherein scintillation-detected radio-activity is metered, the meter and a chronometer being photographed only when the meter input is above ambient radio-activity level, Fig. 2 (not shown).

Title: Phase Control System.
IPC: H04N1/36
Filed: 1967-03-08
Abstract: 1,176,002. Electric synchronizing. RANK XEROX Ltd. 8 March, 1967 [14 March, 1966], No. 10890/67. Heading H2L. [Also in Division H3] The phase angle of a synchronous reluctance motor, e.g. driving a facsimile receiver, is brought into agreement with an incoming signal, e.g. from the motor of a transmitter, by interrupting the supply either for a short period to slip one pole or for a longer period to slip several poles depending upon whether the phase difference is less or greater than a predetermined amount. The phase difference is detected by the logic circuit shown; if slave and master pulses are in phase there is no output at 100, but if they are not, either NAND 25 or NAND 27 will have an output according to whether the difference is less or greater than the time constant of mono-stable multivibrator 24 and an output at 100 is produced by the resultant triggering of mono-stables 28 or 33, the time constants of which are set to cause single and multipole slippage respectively. It is stated that the mono-stable devices may be replaced by bi-stable ones reset by clock pulses and either an electromagnetic or an electronic relay is used to interrupt the motor supply. The phase position detectors are photo-electric.
