IPC: B63B35/04
Abstract: 846,469. Laying submarine cables. SUBMARINE CABLES Ltd. Nov. 11, 1957 [Nov. 9, 1956], No. 34402/56. Class 78 (5). [Also in Group XXXVI] A method of laying a cable provided at intervals with rigid submarine repeater housings or other sections of enlarged cross-section, comprises bridging the repeater housing by a flexible member which is connected to the cable on each side of the repeater housing and also to the housing, so that as the cable passes around a control drum D having a fleeting knife F its place will be taken by the flexible member, which will bear against the fleeting knife in place of the housing which it supports. The flexible member may be a chain 1 having a clamp 2 at each end to grip the cable " C " and a central clamp 3 to grip the housing " H." The clamps may be in two parts 4, 4<1> hinged at 5 and bolted together through flanges 7. To enable the cable to twist within the clamps rollers 8 are provided, these having ribs 9 to grip the cable or housing to prevent axial displacement. In an alternative form (Fig. 4, not shown), the rollers are bobbin-shaped and two semi-circular ribbed inner linings fit within them to grip the cable. Various sizes of cable may be accommodated by changing the rollers of the first type of clamp or the inner linings of the second. The chain should be of approximately the same width as or slightly less than that of the repeater housing, at least over its central portion, to ensure correct juxtaposition of turns around the drum.

The housing seat 70 and wellhead 24 are connected by a breech block connection 66, 76. The housing seat 70 maintains a full 360 DEG circumferential bearing surface with the casing hanger 50. The holddown and seal assembly 180 includes an upper rotating member 182 threadingly engaging the casing hanger 50 and suspending a lower stationary member 184. The stationary member 184 includes a Z-shaped portion 220 composed of a plurality of frustoconical metal rings connected together by connector links so as to provide a positive connective link throughout the stationary member 184. The annular links form grooves for housing resilient elastomeric members where, upon the compression of the Z-shaped portion of the stationary member, the elastomeric members sealingly engage the wellhead and casing hanger to form a metal-to-metal primary seal. The seal is actuated initially by the application of torque through a running tool 200 connected to the casing hanger. The seal is further actuated by the application of hydraulic pressure below the blowout preventer whereby a compression set of the seal is achieved which is greater than the working pressure of the well. The rotating member of the holddown and seal assembly follows the further compression of the seal so as to prevent the release of the compression set upon the removal of the hydraulic pressure. <IMAGE>

Title: Heat-sensitive recording material
Inventor: USAMI TOSHIMASA
IPC: B41M5/28
Filed: 1985-05-15
Abstract: A solution of a substantially colorless dye precursor in an organic solvent preferably boiling at above 180 DEG C is emulsified as droplets, and polymer microcapsule walls are formed therearound; the glass transition point (loss elastic modulus/storage elastic modulus) of the walls is 60-200 DEG C. The latter is achieved by selection of the polymer-forming components, e.g. a polyol or polyamine and a polyisocyanate, or by addition of a transition point modifier, preferably in the organic solution. The modifier can be a carbamic acid ester, aromatic methoxy compound or organic sulfonamide compound. The microcapsules are mixed with a color developer, e.g. a phenolic compound or organic acid, usually with a polymeric binder, and the mixture is coated onto a support of paper or a synthetic film. Coloration on heating, e.g. in a high speed thermal printer, occurs by permeation of coloration reactants through the capsule walls.

Patent GB-2212160-A (GB)
Title: DNA sequence
Inventor: EDWARDS RICHARD MARK
IPC: C12N15/62
Filed: 1987-11-13
Abstract: DNA comprises the sequence 5'-ACCTGCNXXXNNN-3', where each N independently represents any nucleotide and XXX represents a codon such as an initiation codon. The enzyme BspMI recognizes the sequence ACCTGC and gives rise to a staggered cut in the DNA four bases downstream of the recognition site, ie just downstream of the codon, which may be an ATG initiator. This therefore allows for the generation of a blunt end immediately following the ATG by the simple expedient of BspMI cleavage followed by repair of the cohesive end such as with DNA polymerase Klenow fragment. This approach may be used to prepare fused genes and may be found to be superior to other methods of fusing genes without the initiator methionine codon since it is completely independent of the nature of the coding sequence.
