Title: Method of making hydrophobic copolymers hydrophilic
Inventor: ZIEMELIS MARIS J
IPC: C08F2/06
Filed: 1990-03-22
Abstract: A method for altering a macroporous cross-linked hydrophobic copolymeric lattice produced by precipitation polymerization in a solvent of at least one monounsaturated ester monomer and at least one polyunsaturated ester monomer soluble therein, in order to render the hydrophobic copolymeric lattice hydrophilic. The method involves saponifying the hydrophobic copolymeric lattice by reacting the surface of the hydrophobic copolymeric lattice with an aqueous alkali. The surface can also be rendered hydrophilic by polymerizing an acrylate monomer onto the lattice in order to form a surface containing carboxylic acid sites. The carboxylic acid sites formed on the surface of the lattice are converted to carboxylate anions.

Title: Space allocation and positioning method for screen display regions in a variable windowing system
Inventor: BOURGEOIS NANCY E
IPC: G06F3/048
Filed: 1990-07-16
Abstract: In display screen or system technology, a window is a viewing area on the video display.  It may be the full screen region or a smaller region represented within a border of typically rectangular shape into which data from application programs and the like may be written for display.  One or more windows may appear on the face of a video display  screen.   In  the context of the present invention, the window areas are of variable size selected by the operator and resizing of the regions or areas within each variable window must be modified to suit the newly selected window size.  Attributes associated with the regions to be placed within a given window include those for relative priority of display within the window, location within the window and the minimum dimensions of each region to be included within the window.  Program controlled operations examine the minimum specifications for  the  regions  to be  displayed within  a window  in comparison  with  the  operator-selected  window  size  in which the regions are to be displayed, and aportion the available window space among the regions to be displayed in accordance with their relative priority and location in the window and their  specified minimum sizes,  and generate the control parameters necessary for recreating the window display with the appropriate regional spaces allocated and located within the window.

Abstract: TITLE: TRANSFORMER DISMANTLING SALVAGE SYSTEM                        Abstract An automated system for forcibly dismantling used power transformers so that their metal constituents may be recovered for recycling.  A rigid, generally cubicle frame is supported upon a suitable concrete floor.  A cutting carriage is independently suspended from suitable rails attached to the frame for slidable movements toward or away from a receiving station into which transformer to be processed are conveyed. The cutter carriage includes a removable cutter blade configured to compressively shear transformer windings. The cutter carriage cooperates with a reciprocating attack carriage which is slidably suspended for independent movements toward or away from the receiving station. The attack carriage comprises an attack blade having at least one outwardly projecting penetrator which initially stabs and captures transformers to be processed. Both carriages may be hydraulically moved towards or away from each other.  The attack carriage is preferably suspended from the cutter carriage.  When compressed together shearing elements associated with the cutter blade and a specially configured attack plate quickly cut through transformers to aid in the recycling of their metal cores and windings.  Transformers delivered to the receiving station may be lifted into a vulnerable attack position by an elevator. After a transformer is conveyed to the receiving station, it is preferably braced by a pusher plate prior to penetration by the attack system.

Title: Light sources
Inventor: HOLDEN JOHN G
IPC: H01J61/35
Filed: 1990-08-07
Abstract: ABSTRACT OF THE DISCLOSURE     A light source 1 comprises a first layer 2 of plastics material, such as polycarbonate, incorporating two organic fluorescent dyes for emitting respectively, red and green light when excited by radiation of a shorter wavelength.   A second layer comprising of a phosphor material 3a is provided for emitting blue light when excited by an ultra violet radiating discharge caused by energisation of an electrode source electrode 6, the blue light serving to excite the organic fluorescent dyes of the layer 2.   A barrier layer 3, such as phosphate glass, is provided between the first and second layer, 2, 3a which serves to absorb ultra violet radiation and therefore prevents degradation of the first layer 2 of plastics material.   The barrier layer 3 may also serve as a gas-impermeable layer to overcome the porosity of the plastics material of the layer 1.   The red, green and blue light emissions from the device provide a white light source, although light of other colours may also be obtained.

Inventor: BARNES RUSSEL H
IPC: A61B5/00
Filed: 1991-12-03
Abstract: Radiation in the near infrared over a limited range of wavelengths about 1660 nanometers is projected on a portion of the body, for example, the ear, of the patient. The resulting radiation emitted by the portion, either scattered from the portion or transmitted after absorption and scattered by the portion, is processed to derive an expression of the resulting radiation as a function of the wavelength.  The second derivative of this function over a very narrow range of this function between 1640 and 1670 nanometers is expanded and the glucose concentration is determined from the magnitude, or intensity, of the scatter-ed or transmitted radiation at the maximum or minimum point of this derivative.  Also disclosed is apparatus for non-invasive determination of glucose concentration in the patient.  Radiation in the near infrared is transmitted through a first fiber-optic radiation conductor to the outer surface of a portion of the patient's body, penetrating into the portion.  A second fiber-optic conductor transmits the resulting radiation emitted from the portion to data proces-sing means which produces the desired second derivative as a function of the wavelength of the incident radiation.  The processor includes a spectrum analyzer which produces a spec-trum of the resulting radiation.
