Title: Method for preventing supercooling of a latent heat storage composition and a latent heat storage equipment utilizing the same
Inventor: SAITA KENJI
IPC: C09K5/06
Filed: 1995-07-14
Granted: 2007-04-24
Abstract: The invention provides a method for preventing supercooling of a latent heat storage composition comprising one peritectic salt hydrate selected from the group consisting of disodium hydrogenphosphate dodecahydrate, sodium thiosulfate pentahydrate, sodium carbonate decahydrate and sodium acetate trihydrate, water and a water-swellable crosslinking polymer. The latent heat storage composition has a constitution such that a temperature of secondary nucleation of the peritectic salt hydrate is higher than a temperature of secondary nucleation of a lower hydrate, and a part of the latent heat storage composition is always kept at a temperature the same as or lower than a melting point of the peritectic salt hydrate.

Abstract: A compensating positive drive rotary shaft seal assembly comprises a two-part housing (11, 12), each housing part including a radially directed stator surface (30, 31) surrounding the shaft (S). A collar (33) is keyed to the shaft between the stators, and an axially shiftable rotor (37, 38) is interposed between the collar and each stator. The rotors an positively coupled to the collar for rotation with the shaft. An elastomeric annular seal (55) is mounted on the shaft between each rotor and the collar. The housing parts are axially shiftable toward and away from each other adjustably to compress the elastomeric seals and yieldably bias the rotor against the stators. An internal annular gasket (25) spanning the housing parts encompasses the seal assembly and defines a sealed chamber coupled to one or more purge ducts (29).

Title: Methods for dehulling of flaxseed, producing flaxseed kernels and extracting lignans and water-soluble fibre from the hulls
Inventor: CUI WUWEI
IPC: A23K10/30
Filed: 1996-01-24
Granted: 2002-04-30
Abstract: A dry process for dehulling has been developed in order to utilize all components of flaxseed. The dehulling process is composed of three steps: first the flaxseed is dried, then broken (milled) and fractionated by air classification to produce a hull fraction and a kernel (embryo) fraction. Three drying methods, including oven drying, microwave drying and fluid bed drying, were optimized for efficiency of removing moisture by response surface methodology (RSM) and suitability for the dehulling process. Of the drying methods tested, fluid-bed drying appeared most suitable for the dehulling process with satisfactory drying efficiency. Finally, an optimized flaxseed dehulling process consists of drying of the seeds using fluid-bed dryer, milling by barley Pearler and fractionation of the hull and the kernel (embryo) fractions by air classification. The yield of flaxseed hulls and kernels obtained by the optimized process were 22.6% and 72.2%, respectively. The chemical composition of the hulls was carbohydrates 48.3%, proteins 16.8%, crude oil 26.5%, moisture 5.0% and ash 3.5% compared to that of the embryo fraction (carbohydrates 22.0%, proteins 23.9%, crude oil 47.7%, moisture 3.6% and ash 3.8%) on dry base. Lignans and flaxseed gum are extracted sequentially from the hull while the kernels, purified by sieving, are used as a food and/or feed ingredient with or without further processing.

Title: System for cardiac procedures
Inventor: STEVENS JOHN H
IPC: A61F2/24
Filed: 1993-12-17
Granted: 2004-08-31
Abstract: A system for accessing patient's cardiac anatomy which includes an occluding catheter with an expandable member or balloon on a distal extremity of the catheter which when expanded within the patient's ascending aorta separates the left side of the heart from the rest of the patient's arterial system. A cardiopulmonary by-pass is connected to a major vein e.g. femoral, and a major artery e.g. femoral, to withdraw blood from the major vein, remove carbon dioxide oxygenate the withdrawn venous blood and then return the oxygenated blood to the patient's arterial system through the major artery. Preferably, the heart muscle or myocardium is paralyzed by the retrograde or antegrade delivery of a liquid containing cardioplegic material to the myorcardium through patient's coronary sinus and coronary veins. The pulmonary trunk is vented by withdrawing liquid from the trunk through an inner lumen of an elongated catheter or by holding at least partially open the pulmonary valve and preferably also the tricuspid valve which depressurizes the left atrium. The cardiac accessing system is particularly suitable for removing aortic valves and replacing the removed valve with a prosthetic valve.

Granted: 2000-04-11
Abstract: An improved circuit and method of making precise time of arrival measurements on optical pulse data of relatively varying widths.     The  invention  provides  an  analog  input  pulse representing received optical pulse data, along with a delayed version of the analog input pulse.  The time of delay is set such that the original analog pulse and the delayed analog pulse cross each other  at  a  predetermined  point.    This  cross-over consistently occurs at the same point on the signal independent of the size or shape of the analog pulse.  Preferably, the cross-over occurs at approximately 70 % of the analog pulse amplitude. The cross-over point between the original pulse and the delayed pulse triggers the generation of the leading edge of a time of arrival pulse.

Abstract: This process serves to form a long-time-vacuum-tight, high-strength, and corrosion-resistant joint, by means of a joining material, between a first body and a second body each made of sintered, polycrystalline alumina ceramic with a purity greater than 92 wt.% or of sapphire. The joining material is interposed in the form of a paste, a foil, or a slip between the first body and the second body. The joining material has been made from 1) an agglomerate-free, highly disperse, high-purity .alpha.-alumina powder with particles of as high a degree of calcination as possible and of a size not exceeding 100 nm (= 10-7 m), 2) an anorganic oxidic powder of an auxiliary sintering agent with particles of approximately the same size as the particle size of the .alpha.-alumina powder, 3) an organic vehicle which is dissolved or suspended in an organic or aqueous solvant and in which the particles of the respective powder are distributed as evenly as possible. Instead of the anorganic oxidic powder of an auxiliary sintering agent an anorganic oxidic auxiliary sintering agent produced chemically as envelopes around or attachment to the particles of the .alpha.-alumina powder can be used, the total .alpha.-alumina and auxiliary-sintering-agent content of the paste, the foil, or the slip ranging between 50% and 70%. After interposing the joining material the bodies are heated to a temperature of not more than 1,300 °C and then allowing them to cool down. After cooling the alumina content is at least 95 wt.% and the auxiliary-sintering-agent content at least 5 wt.%.
