Abstract: A vehicle having park assist includes a plurality of powered closure doors, each door having an actuator for moving the door between closed and open positions, a plurality of sensors located on the vehicle for sensing objects relative to the vehicle and generating sensed signals indicative of the sensed objects, and a transceiver for communicating with a parked vehicle. The vehicle also includes a controller processing the sensed signals, determining a distance and location of the sensed objects relative to the doors, and determining a parking location for the vehicle in a garage where the closure doors are free from contact with an object in the garage when in an open position and are free of contact with powered closure doors on the parked vehicle. An output is provided to assist a driver of the vehicle to park the vehicle in the garage in the determined parking location.

Abstract: The integrity of membranes utilized on-board marine vessels to separate oil from oily waste water is monitored by conducting the cleansed waste water along a predetermined path through an enclosure within which a surface of such waste water during flow is exposed to a confined body of air so as to effect the extent of light absorbed therefrom into the waste water. Sensing the light remaining in the body of air produces signals from which membrane integrity may be determined based on the presence of an oil film on the air exposed waste water surface.

Abstract: Liquid waste generated aboard a maritime vessel is separated into oily and non-oily components for separate treatment to obtain flow streams having different waste contents. Those of the flow streams having waste content reduced by the treatment are discharged overboard while the other flow streams having concentrated waste content are subject to incineration.

Abstract: A hydraulic system containing a piston-type pump having wear surfaces containing copper or a copper alloy, and, optionally, a vane-type pump having wear surfaces containing steel, uses an antiwear hydraulic fluid having an oil of lubricating viscosity and minor amounts of zinc dithiophosphate and a wear moderating agent. The wear moderating agent can be aliphatic polyol esters, boric acid derivatives of aliphatic polyol esters, aliphatic amines, aliphatic polyamines, aliphatic imidazolines, or mixtures of any combination thereof. The aliphatic groups of the wear moderating agent are substantially straight-chained, and the wear moderating agent contains at least ten carbon atoms.

Abstract: A pulper includes a pulping chamber, a pulping mechanism, and a non-pulpas collection chamber attached to a bottom of the pulping chamber below a top of the pulping mechanism in an annular area outside of the pulping mechanism. The collection chamber includes a container with openings at first and second ends; a basket having an opening at a first end and disposed inside the container wherein at least a bottom portion of the basket includes perforations; a pipe connection located at the second end of the container; means for removing the basket from the container; and means for preventing material from entering a space between the basket and the container; wherein the first end of the container is inserted into the pulping chamber. The collection chamber does not interfere with the fluid flow around the pulping mechanism and can collect a relatively large amount of non-pulpables without requiring pulper shutdown.

Abstract: An antiwear additive has an alkali metal borate; and a thiadiazole compound. That thiadiazole compound may be a 2,5-dimercapto-1,3,4-thiadiazole, a 2-alkylpolythio-5-mercapto-1,3,4-thiadiazole, or a 2-alkylestermercapto-5-mercapto-1,3,4-thiadiazole. If the thiadiazole compound is a 2-alkylpolythio-5-mercapto-1,3,4-thiadiazole or a 2-alkylestermercapto-5-mercapto-1,3,4-thiadiazole, the alkyl group has from one to twenty carbon atoms. If the thiadiazole compound is a 2-alkylpolythio-5-mercapto-1,3,4-thiadiazole, the polythio group has from two to eight sulfur atoms. This antiwear additive can be used with a base grease in a grease composition.

Abstract: A solid waste pulper including a pulping chamber, oriented at an angle, hng a first inlet port for introducing solid waste material to be pulped, and a second inlet port in the pulping chamber for introducing water into the chamber. A blade assembly, preferably formed of a plurality of rotatable blades and a plurality of fixed blades, is mounted in the chamber for pulping the solid waste material introduced in the chamber, the water mixing with the pulped waste material to form a slurry. A sizing ring is provided in the pulping chamber through which the slurry must pass to be discharged, the sizing ring having a predetermined area for limiting the size of the pulped waste material in the slurry which can be discharged from the pulping chamber.
