[Also in Group XXXIII] A water-tight door for an underwater port in the side of a ship (see Group XXXIII), is moved by hydraulic actuators to an open position where it lies alongside the ship's plating 71. The upper hinge comprises a bracket 171, secured to the ship's plating, and a boss 173, secured to the door. Links 166 and 167 are interposed between the boss and the bracket and the whole is joined by pins 177, 179, 180 which have hydraulic actuators 165, 163 and 164 keyed to them respectively. Upon initial opening of the door link 166 is moved anti-clockwise through 90 degrees and link 167 clockwise through 90 degrees, the movement being completed by the door 189 moving through 180 degrees. The Specification describes the hydraulic control circuit for the actuators.
