Abstract: 982,070. Wells; submerged tank fittings. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 21, 1963 [May 23, 1962], No. 20250/63. Headings E1F and E1H. [Also in Divisions B3 and F2] A connection between an operating platform at the surface of a body of water and an underwater installation is established by removably attaching one end of a connecting element to a self propelled submersible manipulator, moving the manipulator through the water to a position adjacent the installation, and attaching the end to the installation. The installation may comprise storage tanks, pipe lines, oil productions handling facilities or waste disposal wells. As shown a vessel 11 is to be connected to an underwater wellhead 19 by a cable 53. Initially a manipulator 35 is lowered on a line 51 to the vicinity of the wellhead, a hook 52 on the cable being secured to a wrench head 43 on the manipulator. The manipulator is propelled by propellers 52a, and guided by means of a television camera 45 to seat on a track 32 on the wellhead, and the wrench head is extended and the manipulator moved to engage the throat 61 of the hook with a part 54a of a bracket 54 on the wellhead. The wrench head is turned to cause a screw 64 to fix the hook to the bracket, and to permit removal of the wrench head from the hook. In a modification the hook is fixed to the bracket by a spring loaded catch, and the hook is carried by claws on the manipulator behind the wrench head. The cable is used as a guide for a marine conductor 56 having a landing head 57. In the modification shown in Fig. 7 the lower end of a pipe spring 92 is attached to claws 94 on the manipulator before being stabbed on the top of the wellhead. The claws 94 may be replaced by a hook having a throat closed by rotation of the wrench head. In the modification shown in Fig. 10 a sleeve 117 on the wellhead 19 is engaged by a connector 119 at the lower end of the guide cable 118, the connector having dogs 120, 121 which engage the bottom of the sleeve. In the modification shown in Fig. 14 the guide cable 134 is initially attached to the wrench head 43 by a cage 132 which is finally attached to the wellhead by a screw 131. In a further modification (Fig. 15, not shown) the lower end of the guide cable has a ring revolvable on a stud for fixing to the wellhead and the head of the stud is adapted to be engaged by a socket on the wrench head, the socket being provided with spring detents for holding the stud head.

Abstract: 731,284. Extracting textile fibres from plant parts. RONCIN, D. Aug. 14, 1952 [July 11, 1952], No. 20498/52. Class 120(1). A method of extracting textile fibres from the leaf stem, &c., of a plant comprises subjecting the plant part to vibrations whose frequency and/or amplitude is varied by causing the plant part to be beaten between a stator and a rotating drum whose periphery is provided with blades extending along generatrices of the drum, and causing relative movement between stator and drum so as to vary the distance, which is preferably not less than half the maximum amplitude of vibrations of the plant part, between the stator and the operative edges of the blades. The frequency may be varied between 20-10,000 cycles per second and the amplitude between 5-100 mm. It is stated that in certain cases, plant parts may be first subjected to low frequency-high amplitude vibrations and later to high frequency-low amplitude vibrations. Fig. 1 shows one form of device for carrying out the method, such device comprising a drum 4, with substantially radial blades 5 (the edges of which may be of corrugated or toothed form) driven from a motor 8, the best positioning'of the blades on the drum being determined by experiment for a given plant. The stator 11, carried by a rod 10, is spring biassed at 15 and movable by a pedal 14 operating between adjustable stops 16a, 16b. An operative, holding plant parts by hand, introduces them through the window 1b in the outer casing 1a, and after action thereon by the rotor blades, he periodically depresses the pedal 14 to vary the distance between rotor and stator. In a modification, Fig. 5, the plant parts are carried along longitudinally. of the drum 24, having blades 25, by belts 31, 32 passing over pulleys 28, 29. The stator part 26 is fixed in relation to the rotor but the part 26a is provided with a moving device similar to that for the stator 11 of Fig. 1.
