Patent number: 4223581Abstract: An apparatus for forcefully feeding cabling in an underwater environment into a container includes a gripper block positionable above the container and an air cylinder for reciprocating the gripper block vertically. Jaws on the gripper block are pivoted to grasp the cabling when the gripper block is reciprocated downwardly but to release the cabling when the block is reciprocated upwardly. This permits forceful feeding of the cabling by mere reciprocation of the gripper block.Type: GrantFiled: March 22, 1978Date of Patent: September 23, 1980Assignee: Combustion Engineering, Inc.Inventor: Jan Markiewicz

Patent number: 4224124Abstract: An electrode is fluid-coupled to the driven electrode, which is directly connected to either an AC or a DC source of potential. The driven electrode is provided with the usual ground electrode to establish the electrostatic field of a coalescing system. The electrode fluid-coupled to the driven electrode is positioned to establish two zones in the electrostatic field. A fluid mixture is passed through the two zones of the electrostatic field, in sequence. The intensity of the field in the first zone decreases as the dispersed polar fluid of the mixture increases, in relation to the less polar fluids of the mixture. At the same time, the field in the second zone increases in intensity. The field gradient shifts between the two zones, in accordance with the quantity of the polar fluid in the mixture passed through the zones in the field, in sequence.Type: GrantFiled: August 30, 1979Date of Patent: September 23, 1980Assignee: Combustion Engineering, Inc.Inventor: Kenneth E. Pope

Patent number: 4224160Abstract: A bottom loaded filter assembly for filtering radioactive liquids through a replaceable cartridge filter. The filter assembly includes a lead-filled jacket enveloping a housing having a chamber therein for the filter cartridge. A track arrangement carries a hatch for sealing the chamber. A spacer plug supports the cartridge within guide means associated with the inlet conduit in the chamber. The plug and cartridge drop out of the chamber when the hatch is unbolted and move laterally of the chamber. During cartridge replacement, a new plug and cartridge are supported in the guide means by a spacer bar inserted across the track means under the chamber. The hatch is then slid under the chamber and bolted to the vessel, engaging an O-ring to seal the chamber.Type: GrantFiled: December 8, 1978Date of Patent: September 23, 1980Assignee: Combustion Engineering, Inc.Inventor: William G.

Patent number: 4220505Abstract: A liquid solution containing a tri-halide from the halogen group consisting of bromine and iodine is passed in countercurrent flow with fluids containing sulfur compounds, including hydrogen sulfide, within a tower. The tri-halide solution removes selected sulfur compounds, including hydrogen sulfide, from the fluids and the halide solution is drained from the bottom of a tower for sulfur removal, electrolytic regeneration, and hydrogen release in order that a tri-halide from the electrolytic cell may be returned to the tower for continual removal of sulfur compounds, including hydrogen sulfide. A portion of the spent halide solution from the bottom of the tower is conducted to a point in the tower above the introduction of the tri-halide solution to prevent the loss of the diatomic halogen.Type: GrantFiled: December 6, 1978Date of Patent: September 2, 1980Assignee: Combustion Engineering, Inc.Inventor: Calvin K.

Patent number: 4217861Abstract: An apparatus for reheating stack gases leaving a plurality of scrubbers which uses water within an associated steam generator as the heating source. A heat exchanger receives heat from the boiler water transferring it to a low pressure fluid which is circulated through heat exchange surfaces downstream of each of the scrubbers. The flow of the high pressure boiler water is controlled in response to a temperature of the low pressure fluid thereby providing a means for minimizing the flow and return temperature of the high pressure water. The high pressure water is taken from a circulating pump discharge and returned to the circulating pump suction.Type: GrantFiled: November 13, 1978Date of Patent: August 19, 1980Assignee: Combustion Engineering, Inc.Inventor: Edward J.
