Title: Fiber-optic sensor and method of use
Inventor: SALOUR MICHAEL M
IPC: G01K11/14
Filed: 1986-08-18
Granted: 1992-03-24
Abstract: Abstract A fiber-optic system for measuring a desired environmental parameter, such as temperature, is disclosed.  The system includes a fiber-optic sensing head that alters light of a prescribed frequency as a function of the environmental parameter to be measured.  Light not of the prescribed frequency is not so altered.  In a preferred embodiment of the fiber-optic sensing head, a semiconductor material is positioned between two substantially parallel optical fibers at a distal end of the fibers.  One fiber serves as in input channel and the other fiber serves as an output channel.  Both fibers approach the semiconductor material from the same direction.  Light channeled to the semiconductor material is reflected at the distal end of the input fiber so as to pass through the semiconductor material, and then is reflected again at the distal end of the output fiber so as to pass back out the output fiber.  The semiconductor material absorbs the light of the prescribed frequency as a function of temperature.  By monitoring the intensity of the light of the first frequency at the output channel, a measurement of the temperature to which the fiber-optic sensing head is subjected can be determined.  To remove the influence of input light intensities, fiber attenuation, and the like, from the temperature measurement, lights of two frequencies, only one of which is the prescribed frequency, are selectively directed to an optical detector through the fiber-optic sensing head and through a separate fiber-optic reference channel.  The four measurements thus obtained at the optical detector -- prescribed frequency through sensing head, prescribed frequency through reference channel, non-prescribed frequency through sensing head, and non-prescribed frequency through reference channel -- are appropriately processed in order to generate a signal that has all variations or influences removed therefrom except the temperature variations of the sensing head.

Granted: 1992-07-21
Abstract: ABSTRACT         Thermoset products are prepared by polymerizing (A) at least one thermosettable compound which contains simultaneously in the same molecule only one maleimide or substituted maleimide group which groups are represented by the formula   wherein each R and R1 is independently hydrogen or a hydrocarbyl group having from 1 to 3 carbon atoms; and only one cyanate group such as 3-(2,5-dihydro-2,5-dioxo-34,329-F     1H-pyrrol-1-yl) phenyl cyanate, and optionally (B) at least one of (1) at least one aromatic polycyanate such as bisphenol A dicyanate; (2) at least one polymaleimide such as N,N'-(methylenedi-p-phenylene)bismaleimide; (3) at least one material having an average of more than one vicinal epoxide group per molecule such as a diglycidyl ether of bisphenol  A; (4) at least one polymerizable ethylenically unsaturated material such as styrene; or (5) a mixture of any two or more of components 1-4 in any combination.  Thermosettable compositions containing (A) and optionally (B) are useful, for example, for preparing castings, laminates and coatings.  Many of the compositions of the present invention possess improved mechanical properties, improved moisture resistance and improved processability.

Abstract: ABSTRACT          Electromechanical operating device for a slidingly mov-able door.          Electromechanical operating device for a slidingly mov-able door, which device comprises a motor driving a worm on which is mounted a nut connected to the door which is is to be moved, said nut being secured in respect of ro-tation by a slide guide having a step at the point corresponding to the end of the stroke of the door. This step allows a certain rotation of the nut and con-stitutes a stop preventing the rearward displacement of the nut when the latter is acted on by means of the door. The nut is composed of two parts axially fastened to one another and mounted for rotation one about the other, these parts being so shaped as to ensure that they will be fastened together in respect of rotation with con-siderable angular play. The aim of the device is to prevent untimely unlocking of the closed door through the elastic torsional cocking of the worm.

Abstract: A  self-centering  seal  for  threaded fasteners and the like consists of a rigid, load-bearing retainer in the form of  a ring  having  an  elastomeric seal molded in place therein at the inner periphery.  The seal is  of  tear  drop  shape  in  section having  a  portion  which  projects  beyond  the  surfaces of the retainer, adjacent recessed portions and  an  inner  tip  portion with a relatively large radius of curvature.  The diameter of the tip portion is sized to be an interference fit  on  the  fastener shank so that the seal may be preassembled with the fastener.

Title: Apparatus and method for storing and processing blood

Granted: 1991-04-09
Abstract: APPARATUS AND METHOD FOR STORING AND PROCESSING BLOOD               Abstract of the Disclosure This disclosure relates to a blood processing and preservation system.  Apparatus of the system comprises a primary collection bag, blood collection means connected to the bag and adapted to draw a unit of blood from a person and feed the blood into the bag, and a harness connected to the bag for conducting solutions and blood components into and out of the bag.  The harness includes first tube means for removing at least one blood component from the bag while retaining another component, second tube means for moving a cryoprotective solution into and out of the bag, third tube means for conducting a wash solution into and out of the bag, and identification means on the bag. The foregoing apparatus is usable in a blood system including the method steps of collecting a unit of blood from a person and delivering the blood to the collection bag, processing the blood to separate the components and removing the components except for the red blood cells from the bag, preparing the red blood cells for freezing by conducting a cryoprotective solution into the bag and mixing this solution with the red blood cells, preserving the red blood cells by freezing, subsequently washing the red blood cells by conducting a wash solution and the cells into and out of the bag, and delivering the cells in the same collection bag to a recipient.  While the foregoing method may be used in a homologous blood system where the recipient is not the donor, it is especially suited for use in an autologous blood system where the blood is reinfused in the person who furnished the blood, and the identification means on the bag assures the recipient that he/she is receiving his/her own blood.  Other blood components, such as the plasma, may also be preserved by freezing.

Abstract: ABSTRACT      A transparent deodorant stick for topical application to human skin comprises a C2 to C4 polyhydric alkanol as a solvent for dibenzyl sorbitol, and additionally a thickening agent.  The stick can also comprise a C1 to C6 monohydric alkanol or a C2 to C6 dialkyl ketone as a co-solvent, and additionally water.  The relative proportions of solvent, co-solvent and water are such that they fall within the area designated ABCDEFGHJKL on the accompanying diagram.
