Abstract: A flowable nondigestible oil composition having a Consistency in a temperature range of 20 ~C to 40 ~C of less than about 600 P.sec(n-1). The flowable nondigestible oil contains a liquid polyol polyester having a complete melt point less than 37 ~C, and a solid polyol polyester having a complete melt point of at least about 37 ~C, wherein the solid polyol polyester contains a solid saturated polyol polyester capable of forming crystallized spherulites.  The flowable nondigestible oil is made by a process which includes the steps of melting completely the nondigestible oil, reducing the temperature of the melted nondigestible oil to a first crystallization temperature less than the onset crystallization temperature of the solid saturated polyol polyester, holding the nondigestible oil at the first crystallization temperature for a time sufficient to crystallize a portion of the solid saturated polyol polyester into crystallized spherulites, further reducing the temperature to an ambient crystallization temperature, and holding the polyol polyester composition for a time sufficient to crystallize the remaining portion of the solid polyol fatty acid polyester. The process is accompanied by shearing of the composition during the crystallization of the remaining portion of the solid polyol fatty acid polyester. The process is generally completed within 5 hours, usually within about 2 hours.

Filed: 1998-09-11
Abstract: A flow-through microcentrifuge comprising a container (70) in which a sample (82) is placed, and a power source capable of rotating the container (70) around an axis. High speed rotation causes the components of the sample (82) to separate according to their respective densities. Pressurized gas (81), a flowing liquid, electromagnetism, or an engine can power rotation of the container. Speeds of the microcentrifuge can reach up to 600,000 rpm, with a corresponding increase in centrifugal acceleration up to 1,500,000 g. In addition to separation, the microcentrifuge can resuspend pelleted material in a liquid by rotating in one direction and then in the opposite direction, repeatedly. The microcentrifuge is also able to mix two or more reagents (118) using this method. Two or more microcentrifuges can be placed together in any configuration and run by the same power source. In the preferred embodiment, several microcentrifuges are used simultaneously to centrifuge samples in multi-well plates (114a, 114b).

Abstract: A ballistic resistant protective garment of multi-component construction for covering and protecting vital portions of the body of the wearer. The garment having layers of composite body armor material which are positioned generally at the strike face portion of the garment. Each layer of the composite body armor material is formed of resin plies having high tensile strength fibers disposed therein. The high tensile strength fibers of one ply are placed in a transverse direction to the high tensile strength fibers of an adjacent ply and a laminate film covers the sub-layer plies enclosing them and sandwiching them together to form a single layer of the composite material. The combined multicomponent construction of the overlying layers formed of laminated plies of aramid and resin with the woven flexible panels of high tensile strength fiber sheets together create a multi-component thin and lightweight ballistic resistant body armor pad. The pad is of such thin and lightweight properties that it meets NIJ Standard 0101.03 standard specifications for Threat Level IIA with an areal density of 0.69 lbs./ft2 with a thinness of 0.17 inches; for Threat Level II, an areal density of 0.84 lbs./ft2 with a thinness of 0.20 inches; and for Threat Level IIIA, an areal density of 0.99lbs./ft2 with a thinness of 0.23 inches.

Patent CA-2311750-A1 (CA)
Inventor: MORIN GUY MICHEL
IPC: H04L7/04
Filed: 2000-06-22
Abstract: Circuits that establish a communication channel over an optical fiber and allow multiple laser wavelengths to behave as a single logical transmission channel. A  sequence, or signature, is added to the data signal and acts as a timing reference at the transmitter and receiver. Coordinating this reference with adjacent circuits at the transmitter, when multiple circuits are used in parallel, enables the receiving circuits, in corresponding numbers to the transmitters, to reproduce the reference synchronization and to extract the transmitted data. The system elements include interconnected transmit circuits, each of which is coupled to a device that generates laser light at a specific wavelength, and are then conveyed through an optical fiber to multiple suitable arrangements of laser light receivers that separate and convert the laser light signals to independent electrical signals, to the interconnected receiving circuits that restore the original data sequence.
Patent CA-2312441-A1 (CA)
Inventor: FANG YI PYGN
IPC: B32B3/24
Filed: 2000-06-21
Abstract: This invention relates to a method for producing a product which exhibits (a) a low level of emissivity and (b) a high level of moisture vapor permeability, and which enables trapped excess moisture to be transported from the product to the surrounding atmosphere while maintaining its effective radiant barrier properties. The product is an underlying substrate, having a pair of outer major surfaces and a radiant barrier material adhered to at least one of the pair of outer major surfaces of the underlying substrate with an adhesive material to form a radiant barrier material covered substrate. A plurality of apertures are formed in the radiant barrier material covered substrate. These apertures extend substantially completely through both the radiant barrier material and the adhesive material thereby forming substantially completely open moisture vapor flow channels which create a high level of moisture vapor permeability through the radiant barrier material and the adhesive material. In this way, a substantial amount of trapped excess moisture can pass from the underlying substrate into the surrounding atmosphere to avoid unwanted degradation of the underlying substrate, while maintaining the low level of emissivity of the product.
