  • Patent number: 4008678
    Abstract: A mooring system is proposed for use at docks where tide changes are large. The system requires two vertical mooring posts positioned on the dock at a distance apart so that when the ship is docked one will be at a bow section of the ship and the other at a stern section. The ship is fitted with two post-engaging devices, one in the bow area and one in the stern area, each of which will be in alignment with the appropriate mooring post. The post-engaging devices are mechanically movable so as to engage the adjacent post and the engagement will prevent horizontal movement of the ship, but will permit vertical movement in accord with the tides.

  • Patent number: 3996031
    Abstract: A process and system for separating a preferentially crystallizable component A from a feed, wherein a series of zones are used between which mother liquor can flow without passage of crystallized material. Liquid feed is introduced to a zone other than the end zone from which effluent rich in component A is withdrawn. During one stage gradating crystallization temperature pattern is established throughout the series ranging from relatively low to relatively high, causing component A to crystallize in each zone; and mother liquor is caused to flow toward the low temperature end, while a portion of previously withdrawn effluent rich in component A is returned to the higher temperature end and effluent lean in component A is removed from the lower temperature end.

  • Patent number: 3996030
    Abstract: A process to separate hydrocarbon gases into different fractions by condensing in the high pressure condenser of a staged dual pressure rectification system only that amount of vapor necessary for the reboiler duty of the low pressure column and expanding the excess vapor to provide the low temperature refrigeration duty.
