Title: Apparatus and method for installing
IPC: E21B43/013
Filed: 1970-05-15
Abstract: 1309600 Installing cables SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 15 May 1970 [19 May 1969] 23684/70 Heading H2C [Also in Division F2] The invention relates to a coupling for, and a method of, connecting a plurality of coextending conduits 32 or cables to an underwater installation (e.g. a wellhead), provision being made for correctly rotationally aligning said conduits to be co-operable with installation conduits 28, Fig. 4. As described conduits 32, adapted to lie on the bed of a body of water, are pulled by cable 37 via disconnectable connector 38 engaged in a pulling head 39. The pulling head is secured to the conduits 32, and the cable is threaded through an anchoring means 30 which may be lowered on to the installation from a drilling barge. The pulling head 39 is received in a receiving portion 45 of an anchoring means, Fig. 6, a projection 47 of the latter engaging a helical ridge 48 on the pulling head to rotate the latter as it is pulled in. When rotationally aligned, the spring urged detents 50 lock the connection and further tension in the cable 37 releases the connector 38. A sleeve 55, Fig. 4, may then be hydraulically operated to release pins 53 engaged in an external groove 54 on the receiving portion 45, and piston 72 is then used to axially separate the cable guide 40 therefrom. The cable guide may be raised axially by piston 44 so that the end of the pulling head 39 and the connectors 29 cooperating with installation conduits 28 can be brought together. This may be achieved by moving the receiving portion 45 leftwards by means of jacks (63) (Fig. 5, not shown). Alternatively a piston 58, Fig. 6, telescopically engaged with conduits 28 and bearing connectors 29, may be moved rightwards in cylinder 56, or a combination of both movements may be used. When connected, the connectors 29 fit within corresponding bores 49 in the pulling head 39, which are in turn associated with the conduits 32. Hydraulic actuation of sleeve 62 carries dogs 60 into a groove 61 to lock the connection. The invention may also be applied to making electrical connections, Specification 1,161,616 is referred to. Reference has been directed by the Comptroller to Specification 1,071,155.

Patent GB-872214-A (GB)
Title: Extraction process for the recovery of heparin
Filed: 1958-07-30
Abstract: Heparin is recovered by extracting defatted animal tissue with a salt solution maintained at a pH between 7 and 10 and of sufficient concentration to produce an anion concentration of between about one mole per litre of mixture and about saturation, and recovering heparin from the mixture.  The preferred salt employed is sodium chloride at a concentration of at least about 60 gms. per litre, preferably 100 to 150 gms. per litre.  Other salts specified are the alkali metal and ammonium citrates, halides, acetates, sulphates or thiocyanates or alkaline earth halides, acetates or citrates.  The extraction temperature may vary from 0 DEG -100 DEG C., preferably 20 DEG -60 DEG C.  Heparin may be recovered from the salt extract, after filtration, by acidification to a pH of less than 4 to precipitate the protein, separating the protein by centrifugation or filtration, and recovering the partially purified heparin from the filtrate by addition of an alcohol, acetone, or other water miscible organic solvent.  When the soluble salt used in the extraction is not very soluble in the water-miscible solvent, it is desirable to subject the filtrate to dialysis before precipitating heparin or to dissolve the precipitated heparin in water, dialyse the solution and then reprecipitate the heparin.  Heparin can also be recovered by acidifying the salt extract to precipitate the protein, separating the protein by filtration, and adding a fatty amine such as octylamine or dodecylamine to the filtrate to precipitate an amine-heparin salt.  The heparin is recovered from the amine-heparin salt by reslurrying the salt in water with an alkali at a pH of about 10 to dissociate the salt, filtering, and adding alcohol or acetone to the filtrate to precipitate the heparin.  A further method of recovering heparin from the salt extract comprises removing the salt from the original extract by dialysis, acidifying the dialysate to a pH of less than 4 to precipitate the heparin-protein complex, redissolving the complex in water at a pH between about 7 and 10, adding sufficient water soluble salt to the mixture to produce an anion concentration of between about one mole per litre of mixture, and about saturation, acidifying the mixture to a pH of less than 4 to precipitate the protein and separating the protein and recovering heparin from the remaining solution by adding methyl or ethyl alcohol or other water miscible organic solvent.  Specification 754,885 is referred to.
