Abstract:
A system is provided for positioning separate portions of a sample in elongate, parallel channels of a sample chamber and for irradiating a sample in the chamber to create a diffraction pattern where the sample and chamber differ in refractive index. The system also can measure absorption of electromagnetic radiation by a sample in the chamber, and can measure the absorption simultaneously with measurement of diffraction by the sample.
Abstract:
This invention is of a method and equipment for reducing stress concentrations in a body supported in a horizontal or any reclining position up to and including a fully seated position. The stress reduction is accomplished by means of specially designed or arranged cushioning material contained inside a membrane or bladder wherein the pressure of a fluid inside the membrane can be controlled as a means of varying the cushioning effect (compressibility) of the material inside and holding the cushioning material in specific places to reduce fight-back of the material over supporting edges that may otherwise create undesirable shear on the supported body tissue.
Abstract:
A connector for use underwater or in a wet or severe environment comprises first and second connector parts adapted to be interengaged to establish an electrical connection. The first connector part has at least one pin, and the second connector part has at least one electrical contact for engagement by the pin when the connector parts are interengaged. The pin comprises an axially extending electrically conductive portion and an axially extending electrically insulating sleeve around said conductive portion, and the pin is supported by and projects axially forwardly from a support whereby its insulating sleeve is exposed along a longitudinally extending portion thereof to ambient conditions when the connector parts are disengaged. The connector part has a protective rigid metal sleeve member arranged to extend at least partly along the first portion of the insulating sleeve and at least partly along the second portion thereof.
Abstract:
A rapid doffing and donning vest uses a clam shell design wherein the ends of the cummerbund are removably attachable to the rear panel. A blade on the cummerbund mates with a receiver on the rear panel and has a plunger hold the two together. The plunger is attached to a pull strap located on the front panel's shoulder strap via a cord. As the pull strap is pulled outwardly, the cord pulls the plunger away from the mated blade and receiver and allows the two to decouple detaching the cummerbund from the rear panel. Outward pulling on the pull strap also facilitates decoupling of the shoulder strap from the rear panel. When the vest is doffed, the front panel and cummerbund remain attached to each other and detached from the rear panel.

Abstract:
A nano-molding process including an imprint process that replicates features sizes less than 7 nanometers. The nano-molding process produces a line edge roughness of the replicated features that is less than 2 nanometers. The nano-molding process including the steps of: a) forming a first substrate having nano-scale features formed thereon, b) casting at least one polymer against the substrate, c) curing the at least one polymer forming a mold, d) removing the mold from the first substrate, e) providing a second substrate having a molding material applied thereon, f) pressing the mold against the second substrate allowing the molding material to conform to a shape of the mold, g) curing the molding material, and h) removing the mold from the second substrate having the cured molding material revealing a replica of the first substrate.
Abstract:
The present invention provides a method of forming a molecular membrane using soft lithography. The method includes forming a pattern having at least one nanoscale feature in a moldable polymer composition and deploying at least a portion of the pattern adjacent a first substrate.
Abstract:
A method of manufacturing a submergible machine protector bag comprising providing a tubular woven sleeve of reinforcing material, fitting the sleeve over a mandrel, embedding the sleeve in a waterproof elastomeric material to form a bag body and removing the bag body from the mandrel.
