Abstract: A marine engine quick drain system is provided having multiple drainage tubes connecting each drainage point on the marine engine to a water removal device. The water removal device is operable to drain water from all drain ports within the engine simultaneously, routing all drain ports to single point drain which is preferably connected to vacuum for evacuating fluids from the marine engine. Fittings are provided to connect each drainage tube to each drainage point on the marine engine. Integrated within each fitting is a fluid sensor which indicates the presence of water in each part of the engine. Each sensor is connected back to a central control console having a microprocessor which will control the water removal device and verify that the marine engine has been drained properly or if there is water in the marine engine.

Abstract: The sizing screen comprises a plurality of rotatable screening decks mounted co-axially one below the other. The uppermost screening deck is rotated at a slower speed than the relative fast revolving lowermost screen deck.

Abstract: A sizing screen for particulate material of different sizes has a generally horizontal rotatable circular screen surface having a plurality of elongate radially projecting members, first collection means positioned adjacent the outer periphery of the surface for collecting an oversize fraction of the particulate material, second collection means positioned below the surface for collecting an undersize fraction of the material which passes through the screen. Discharge means comprising a rotatable table partitioned into different parts for carrying the oversize and undersize material is positioned below the first and second collection means. A plough or paddle preferably urges material from the table into outlets. The screen is suitable for handling sticky material such as coal fines and clay.

Abstract: A sizing screen provided with feeder means for causing an even distribution of material onto the screen surface. The feeder means comprises a generally spirally shaped plough which urges material over the edge of a generally circular table the distribution of material being substantially uniform over the edge. The plough has a compaction zone for compacting the material so that urging forces exerted by the plough are not absorbed in the material. A chute which can be stepped feeds material onto the table through the plough.
