Abstract: A device for a curved conductor pipe for a pull wire wherein the conductor pipe is provided along the inside thereof with a lining which has a material yield point that is higher than the compressive force that operates between the lining and the pull wire. The lining is equipped with a guide seat for the pull wire in order to distribute the compressive force from the pull wire over the lining.

Abstract: A seine ring which is equipped with a replaceable wearing piece, where the wearing piece is affixable to the mount part of the seine ring adapted for this function by means of a nut and bolt connection which is fed through a hole in the mount part. The hole is formed such that, seen from either side and along the axis thereof, it tapers towards the axial center of the hole. The wearing piece is given a clearance in relation to the mount part to facilitate its ability to tilt in relation to the mount part.

Abstract: A compensating device equipped with a hydraulic cylinder/piston arrangement as a damping member, and a sheave operatively connected with the cylinder and piston arrangement, and a hydraulic accumulator connected to the cylinder, for use on board a trawler vessel operating in autotrawl mode for dampening shock forces or alternating stresses on trawl pulling wire elements between the trawler vessel winch system and a bottom trawl.

Abstract: A melting furnace has a supporting structure of thermostable steel, and an internal shell of common steel, serving as a contact area for the refractory lining of the furnace.

Abstract: Retractable tow line guide pins (1 and 2) at the stern of a tugboat or supply boat are made to be elevated from/retracted into the deck (3) of the vessel and are also pivotable, such that over a portion of the raising or lowering movement they are pivoted 90.degree., whereby fixed locking members (4,5) mounted thereon and the pins themselves pivot from an inoperative position into a position in which the opening between the pins (1 and 2) is closed at the top, thereby preventing a tow line disposed in the opening between the pins from being released therefrom.

Abstract: A stop assembly on a vessel for securing a buoy line connecting a mooring anchor and an associated buoy, comprising at least one fork-shaped stop member which is mounted so as to be raised up from and lowered down into the deck of a ship and which can be remote-controlled from a command location, the opening between the arms of the fork being wide enough to provide room for the buoy line, but narrow enough that an expansion on the line, for example, a swage sleeve, rope wire thimble or the like will be restrained so that the line is securely locked in position.

Abstract: Control means for two trawl winches having separate motors and supply systems, each motor having a shunt line which is connected to the shunt line of the other motor by a pressure operated value for opening of either one of the shunt lines.
