Abstract: 1,058,110. Boring earth; wells. PAN AMERICAN PETROLEUM CORPORATION. Nov. 5, 1964 [Feb. 7, 1964], No. 45226/64. Heading E1F.  Apparatus for conducting operations in an underwater well comprises a floating vessel positioned directly above the well, an elongated element extending from the vessel into the well, sensing means positioned to bear against the element when the vessel is laterally displaced a predetermined distance and to provide an indication of the displacement. The element is a drill string 28. which passes through a rotary table 30 on the vessel 11. The indication of the displacement is a measure of the stress in the string and indicates when the vessel should be relocated to maintain the stress in the string at a safe level. The well 13 has a surface casing 18 supporting a conductor pipe 16 including blow-out preventers 21, a spool 22 and a flexible joint 26 and connected to the vessel by cables 17. The spool encloses a  sleeve 31 and carries the sensing means 23, the arrangement being that displacement of the vessel causes the drill string to engage the sleeve which is caused to load one or more of the sensing means. The sensing means each comprise a compression member mounting strain gauges attached to a bridge circuit provided with an indicator or recorder, or a plunger capable of acting on a fluid connected to a pressure indicator, the indicators being calibrated to show displacement of the vessel. In modifications the sensing means may be located in or adjacent the rotary table, or at the top of the conductor pipe.

A vertical frame 21 which carries load engaging forks 29 is connected to the mast 15 by a pair of sets of crossed links 25, 26 which are expanded and contracted by a ram 28 to move the frame 21 relative to the mast 15. When a rack loading or unloading operation is taking place the guide assembly 1 is adjusted to the required height on the main mast, the turntable 13 is rotated to position the tracks 14 relative to the rack and the carriage 16 and thus the mast 15 and forks 29 are moved along the tracks 14, the rollers 30 on the lower sides of the tracks 14 engaging in skids (34) in the rack, thus stabilizing the truck, Fig. 5 (not shown). The forks 29 may be moved vertically relative to the rails 14 to permit the forks to be manipulated below an article stored in the rack, such movement of the forks being effected upon relative movement between parts of the secondary mast 15.

Title: Process for the manufacture of graft copolymers of vinyl esters
IPC: C08F271/00
Filed: 1963-11-15
Abstract: Graft polymers are made by polymerizing one or more vinyl esters in the presence of one or more polymers of open chained tertiary N-vinylamides and in the presence or absence of an organic solvent for the polymers.  Preferred vinyl esters are the acetate, propionate and benzoate, which may be used in admixture with other monomers, e.g. acrylic, methacrylic, crotonic, maleic and fumaric acids and the amides, nitriles and esters thereof. The preferred preformed polymer is poly-(N-vinyl-N-methyl acetamide), which may be used in solution in, or swollen by, methanol or tertiary butanol.  The graft polymerization is initiated by the use of a peroxide, azo or redox catalyst. The examples describe grafting vinyl acetate, propionate and benzoate, and a mixture of vinyl acetate and crotonic acid on to poly-(N-vinyl-N-methyl acetamide).  The graft polymer derived from crotonic acid is soluble in aqueous ammonia.
