Abstract: A system is provided for determining the tensile characteristics of a sample under dynamic conditions. The system includes an apparatus adapted to accelerate the sample to a desired test velocity and maintain the test velocity through a predetermined test run, and a microprocessor for controlling the apparatus, data collection and data evaluation. The apparatus is formed with two movable clamping jaws for engaging the sample and sensors for measuring characteristics necessary to determine the stress-strain characteristics of the sample. During the course of the test, a sample is accelerated to a predetermined test velocity and one end of the sample is caused to be instantaneously fixed. The other end of the sample is then translated away from the fixed end at the test velocity. A closed loop between the microprocessor, a linear encoder measuring velocity, and a linear motor can be formed to accordingly adjust and maintain the desired test velocity.

Abstract: There is provided a valve for use in regulating flow of fluid through a conduit having a deformably resilient valve sleeve, in which the valve includes a housing, and at least first and second opposing jaw members disposed transversely to the conduit for deforming the valve sleeve with the conduit sandwiched between the first and second opposing jaw members. The jaw members are movable between an open position, with the first and second jaw members spaced apart a distance sufficient to permit flow of liquid through the conduit, and a closed position, with the jaw members pinched together sufficiently to restrict or shut off the flow of fluid through the conduit. Inflatable diaphragms are provided to control movement of the jaw members between the open position, when the diaphragms are in a deflated configuration, and the closed position, when the diaphragms are in an inflated configuration.

Abstract: An oil recovery and storage ship having a general tank configuration of a conventional crude oil carrier is modified by providing inlet doors along opposite sides of the ship and a deployable floating boom arrangement for maximizing the floating oil gathering swath. The side inlet doors open into sluice or sea-calming compartments which have adjustable weir doors opening into primary separation tanks on port and starboard sides. Adjustable weir doors open from the primary separation tanks into a secondary separation tank. A selected number of cargo tanks are interconnected by conduits which permit the flow of liquid from one tank to the next in a series or cascade manner to decant oil from oily water and to discharge substantially oil-free water overboard from the last tank in the cascade. The ship may be used as a conventional liquids carrier when not required for oil spill recovery operations.

Abstract: A simplified glove donning device to inflate and detect pinhole size leaks in elastic gloves using no internal or external energy sources. The device may be mounted to any flat surface. Glove donning cylinders (100) hold elastic gloves securely in place and forms an air tight seal between cylinder (100) and elastic glove. When a hand is inserted into the cylinder (100), sealed with an elastic glove, air in the cylinder is forced out through a one-way check valve (400). When the hand is retracted slightly or fully, the elastic glove is pulled into the cylinder (100) by the vacuum developed below the glove, thus, it expands larger than a hand. The user may then insert a hand friction free and disengages the glove from the cylinder (100) by rolling the cuff up and off the upper edge (130) of the cylinder (100). When the air tight seal is broken, the glove deflates rapidly and conforms to the shape of the hand with no air pockets at the finger tips.
