Title: Transmission line branching device
Inventor: YOMOGIDA TOSHIHIKO
IPC: H04L12/437
Filed: 1989-10-13
Abstract: In a branching device which sends out data received at an arbitrary one of three terminals thereof through the other two terminals, the terminals are coupled to each other via photo-couplers. The head of a data block received by each receiver connected with each terminal is detected, a signal which specifies the length of the data block is generated and reception of communication data by way of the other two terminals is inhibited while transmission of the communication data is enabled. 
<??>Since the transmission lines of the three directions are electrically isolated from each other by the photo-couplers, even when a failure of short-circuiting occurs at a main transmission line or a branch line or the like, communications are continued bypassing the location of the failure.

Patent GB-2233367-A (GB)
Title: Composite guide line
Inventor: HOPPER HANS PAUL
IPC: E21B41/10
Filed: 1990-06-12
Abstract: A composite guideline for use with sub sea installations has a latch, preferably a releasable latch, attached to the end of a large diameter cable 17 and a tie joint joining the large diameter cable 17 to a smaller diameter cable 3, which forms the main length of the guideline. The composite guideline thus provides a length of large diameter, strong cable in the vicinity of the sub sea installation to take the strain of landing equipment on it. The tie joint may be a shear joint or be associated with a shear joint and there may be associated flotation collars 18. The composite guideline allows guideline operation at greater sea depths than hitherto and enables a variety of equipment to be run and landed. Drill bits, well casing and other relatively light weight units can be run down composite guide lines using a guidance damping tool, which grips the large diameter cable to reduce swing and heave to an acceptable level before the unit is landed.
