Abstract: ABSTRACT OF THE DISCLOSURE            The present invention related to a method and an apparatus for treating waste water for ships, and an apparatus for treating waster water on ships in a closed system. The waste water flows upwards through a liquid-solid  separation column having a plurality of downwardly slanting bubble generating plates projecting alternately from opposed inner walls of the column. A small space is formed between the free end of each of the plates and the inner wall opposed to it. Each of the bubble generating plates includes an open cellular plate-like member and a pressurized  gas distributing channel formed within the plate-like member and extending substantially parallel to the plane of the member. Suspended solids are separated from the waste water in this column and are accumulated in a concentrated state beneath of the plate-like members by flotation with bubbles generated in the bubble generating plates. The suspended solids are reduced to below 1,000 ppm and the resulting treated water is clarified by passing it through a semipermeable membrane treating system.

Abstract: 45,674 PUFFER-TYPE GAS-BLAST CIRCUIT-INTERRUPTER HAVING VARIABLE-AREA STATIONARY COMPOSITE PISTON STRUCTURE              ABSTRACT OF THE DISCLOSURE           A puffer-type gas-blast circuit-interrupter is provided having an operating cylinder movable over a fixed composite piston structure, the fixed composite piston structure providing a variable cross-sectional area by means of a secondary piston area, preferably annular in configuration, which is releasably latched in a fixed forward position, and, subsequently, during the opening operation of the breaker, collapsed to a retracted position.           The composite piston arrangement may be such that upon collapse of the secondary "fixed" piston, the diameter of the surrounding movable operating cylinder may be such as to closely surround the central area of the primary fixed piston structure to retain high-pressure gas within the piston-compression chamber without loss.        There results, by the utilization of the variable-area fixed composite piston structure, an improved inter-rupting performance of the circuit-interrupter by giving very high gas pressures early in the opening stroke of the circuit-interrupter, as compared to prior-art conventional structures, which proved such high gas pressure only at a later time in the opening stroke by conventional piston means.

Abstract: RESISTIVE ELECTRICAL  PROTECTION DEVICE          Abstract of the Disclosure Several embodiments of a circuit protective device are disclosed that rely on a unique, spring-biased housing that cooperates with a leaded fusible element to effect a reliable open-circuit condition in response to a predetermined overload condition.  The leads not only provide the means for interconnecting the device with associated circuitry, but are specially configured to provide a simplified, inexpensive and reliable way of normally holding the assembled device together, in opposition to a predetermined closed circuit tensional biasing force applied thereagainst by the housing during normal operation.  The leads may also advantageously be configured during the assembly of the device to provide the means for directly mounting the device on, and optionally (with pre-formed stops) in spaced relationship with, a circuit board.      In several preferred embodiments, the fusible element comprises a leaded resistor of a type that is capable of fracturing when subjected to a predetermined overload condition and, thereby, producing a reliable open-circuit condition when separated into two sections by the force imparted thereagainst by the spring-biased housing.
