Title: Backgammon multi-player game
Inventor: HOLSTEIN ROBERT A
IPC: A63F3/00
Filed: 2001-02-28
Abstract: The invention is a new variation on the game of backgammon. The game consists of six colour-coded game boards and six sets of coloured playing stones (15 per set). This game allows 3-6 players to challenge each other to be the first player to successfully bear off all of his or her stones. To accomplish this, each player moves his or her stones around the board from point to point (space to space) as per the roll of the dice towards their own colour-coded home base. During the process they must try to avoid leaving "blots" (a single stone on a point) that make their stones vulnerable for a "hit" (another player landing on their blot). A "hit" from an opponent will send their stone "to the bar" (back to the beginning). At the same time, each player will try to prevent their opponents from reaching their own colour-coded home bases. Once a player has all of his or her stones in their colour-coded home base, they are able to start "bearing off" (removing stones from play).

Abstract: The invention relates to a method for preparing an albumin isolate from a substance containing albumin, according to which the substance is first grou nd to a flour and the flour suspended in an aqueous solution. The albumin is th en extracted from the flour and introduced into the solution by means of at lea st one countercurrent protease. The albumin is extracted from the solution by precipitation using a mineral acid and then neutralized. The aim of the invention is to improve said method in such a way that the albumin is extracted from the solution and introduced into the solution by way of a process comprising at least two steps and carried out using the at least one  protease, at a pH greater than 8 and at a temperature of between 30 and 60 ~ C. In the first step the flour is treated at a lower concentration of the at least one protease, in relation to albumin weight, at a lower pH and at a higher temperature than in the second step. After the first step a first upp er flow of a fraction containing the flour is separated and the albumin separat ed from said fraction by precipitation, and after the second step a second uppe r flow of a fraction containing the flour is separated and fed back to the fir st step.
