Abstract: A footwear article comprises: an outsole comprising: an outsole body comprising a first polyurethane polymeric material attached to one or more tread cleats comprising a nitrile butadiene rubber polymeric material; and a footwear upper affixed to the outsole, the footwear upper comprising a second polyurethane polymeric material. Footwear articles, including boots, overshoes, and/or work shoes, are effective to meet or exceed slip resistance in accordance with ASTM F3445-21. Methods of making the footwear articles are also described.

Abstract: A boot comprises: an outsole and a polymeric upper affixed to the outsole. The upper comprises an upper body and a gusset, which comprises a relaxed position and an expanded position, wherein the gusset moves from the relaxed position to the expanded position to accommodate a wearer's leg upon donning of the boot.

Abstract: A boot comprises: a shell comprising a first foamed polymeric material; a sock liner comprising a second foamed polymeric material, the sock liner having an exposed section and an enclosed section; and an adhesive layer affixing the shell and the enclosed section of the sock liner; wherein there is an absence of intermingling of the second surface of the enclosed section of the sock liner with the inner surface of the shell. Methods of making and using the boot are also provided.

Abstract: A boot comprises: an outsole and an upper affixed to the outsole, the upper comprising a polyvinyl chloride (PVC) upper body and a composite toe cap. The composite toe cap comprises a fiberglass reinforced polymer, and the composite toe cap comprises a tapered surface.

Abstract: A polymeric outsole for an article of footwear comprises: an outsole body and a tread pattern that comprises a plurality of cleats and channels between the cleats; and one or more tread ribs projecting from the outsole body. The tread ribs project a first distance from the outsole body that is shorter than a second distance that the cleats of the tread pattern project from the outsole body. The tread ribs are effective as wear indicators to indicate remaining useful life of the cleats. During a first duration of wear, the tread ribs are not in contact with a ground surface while the cleats are in contact with the ground surface, and during a second duration of wear, both the tread ribs and the cleats are in contact with the ground surface.

Abstract: The tissue disaggregator device includes a base having a multiple well array. Each of the wells includes a screen embedded into bottom portion of the well. The device removably connects with standardized plate and allows for multiple fold increase in tissue sample preparation.

Abstract: A system to collect by vacuum conveyance, separate, and discharge two mixed immiscible liquids with different specific gravities comprising a prefilter vessel 200, a vacuum tank 100, an optional heavy phase intermediate separation stage 40, and an optional light phase intermediate separation stage 30. Vacuum tank 100 is under a constant regulated vacuum, which sucks mixed immiscible liquids with different specific gravities from their respective remote source(s) through conduit(s) connected to vacuum tank 100. Collection conduits can have manually, mechanically, or electro-mechanically controlled valves at their source ends. Any grit, sediment, particles, and/or floatable debris in the collection conduits is first removed, and then any entrained air in the mixed liquid stream is removed, from the mixed liquid stream prior to undergoing any phase separation stages. Initial phase separation occurs automatically in vacuum tank 100 without any phase interface detection devices.

Abstract: A system to collect by vacuum conveyance, separate, and discharge two mixed immiscible liquids with different specific gravities comprising a grit, sediment, particulate, and floating debris removal/collection chamber 11, vacuum tank 51, optional heavy phase supplemental separation stage 47A, and optional light phase supplemental separation stage 47B. Vacuum tank 51 is under a constant regulated vacuum, which sucks mixed immiscible liquids with different specific gravities from their respective remote source(s) through conduit(s) connected to vacuum tank 51. Collection conduits can have manually, mechanically, or electro-mechanically controlled valves at their source ends. Any grit, sediment, particles, floatable debris, and entrained air in the collection conduits is removed from the mixed liquid stream prior to undergoing any phase separation stages. Initial phase separation occurs automatically in vacuum tank 51, which provides quiescent conditions for gravity separation of mixed immiscible liquids.

Abstract: A dockside system for the collection and disposal of bilge water, waste oil and the like is described for continuously evacuating waste liquids from waterborne vessels (16, 18) into a shore vacuum tank (24) and for simultaneously and automatically separating oil and water from the waste liquid. A continuous regulated vacuum is applied near the top of the vacuum tank (24) for sucking waste liquid, such as bilge water and oil, through tubes (30, 33, 82) into the tank. The tubes have manually operated on/off valves (34) at outer end portions thereof which are operated at the bilges of the waterborne vessels.
