Patent CA-2115051-A1 (CA)
Title: Digitizer with serpentine-type conductor grid having uniform conductor repeat increments
Inventor: MCDERMOTT ROBERT M
IPC: G06F3/047
Filed: 1992-08-06
Abstract: Disclosed herein are position determining apparatus and conductor structures or grids therefor.  The conductor structure for each axis includes a number of conductors which are run in a serpentine-type path each with uniform repeat increment.  The repeat increment, which is the spacing or span between one run and the next of the same serpentine-type conductor, are uniform for each conductor (but may change from conductor to conductor) and is constrained by a maximum repeat increment, or a minimum repeat increment.  In the preferred embodiments, there is at least a constraint on the maximum repeat increment to provide noise immunity.  The conductors are arranged for each axis of the grid in a pattern such that signals obtained for that axis may be processed to provide binary numbers in a Gray-type code, each unique to a small region of the active area in which the coil center is located.

Abstract: Provided herein is a novel method of game play and game components that in one embodiment are in the form of trading cards (10, 12, 40, 42, 44, 48, 54, 60, 64). However, the game components may take other forms, such as a board game, or the game may be played in different media, such as electronic games, video games, computer games, and interactive network. In one version, the game components comprise energy or mana cards 40 and command or spell cards (10, 12, 42, 44, 48, 54, 60, 64) having commands or spells associated therewith that utilize the energy to enable a player to attack, defend and modify the effect of other mana cards, spell cards, and the fundamental rules of play. The goal of the game is to reduce the life points of other players to a level below one. In this game of strategy and chance, players constrict their own library of cards, preferably from trading cards, and play their library or deck of cards against the deck of cards of an opposing player. Cards may be obtained from retail outlets, trading with other players or collectors, and winning cards at games and tournaments.

Title: Selective Crosslinking of Hemoglobin by Oxidized, Ring-Opened Saccharides
Inventor: PLIURA DIANA
IPC: C07K14/805
Filed: 1994-03-11
Abstract: Hemoglobin for forming the basis of blood substitute is modified by crosslinking it by reaction with a polyaldehyde produced by ring opening oxidation of a di/tri-saccharide such as raffinose, wherein the o-saccharide solutions are maintained and the reaction is conducted at a pH from about 5.0-7.0, and at a stoichiometry from about 1:1-4:1 based upon the molar ratio of di/tri-saccharide to hemoglobin tetramers, followed by appropriate reduction of the Schiff base linkages so formed to stabilize them. Careful control of the pH of ring opening of the di/tri-saccharide ensures consistent production of the polyaldehyde without unwanted side products and reaction of this product with the hemoglobin at the specified stoichiometry leads to high yields of stabilized, tetrameric hemoglobin and oligomers thereof of predetermined composition and beneficial properties.

Title: Method for the production of fiberboards
Inventor: HOFMANN MICHAEL
IPC: B27N1/02
Filed: 1994-04-14
Abstract: A method for the production of fiberboards made from pieces of wooden particles,and a polyurethane glue used as a binder in an amount of less than 10 percent by weight is described, in which the wooden particles are heated by pressurized steam and thus refined into fibers, the fibers being subjected to a blow line, being dried in a drying device, and then formed in the shape of a mat and pressed to form the fiberboards. The fibers are applied in an amount resulting in a bulk density of the whole fiberboard of approximately 550kg/m3 to 650 kg/m3. The binder is applied in an amount of 0.5 to 4.0 percent by weight, preferably in the range of 1.0 to 3.0 percent by weight, with respect to dry wooden particles. The steam generated during the heating of the wooden particles is passed through the drying device without having a portion thereof separated out and is used with the binder to form a coating layer out of polycarbamide to prevent the fibers from forming a preliminary reaction with the binder.
