Patent CA-2227429-A1 (CA)
Inventor: REES WILLIAM GERAINT
IPC: C10L5/46
Filed: 1996-07-22
Abstract: A chemically bonded medium is obtained from a resilient organic macromolecular material, in cut elongate of finely divided form (such as grass or peat). The material is dried (3, 4) under conditions permitting escape of water vapour, such that the dried material has a predominantly hydrophobic surface and a water content of not more than 10 % by weight; and then optionally flashed.  The surface properties of the dried material are then equilibrated, under conditions inhibiting escape of water vapour and other volatiles, such that the predominantly hydrophobic surface is rendered predominantly hydrophilic.  The product is then mixed (5) with a lignosulfonate, with application of heat in an amount sufficient to maintain the lignosulfonate in fluid form, such that the lignosulfonate forms a coating film on the surface. The lignosulfonate is caused to undergo partial polymerisation (6) (typically by heating and/or treatment with oxygen) on the surface of the dried material to produce a flowable, substantially non-resilient and non-tacky, chemically bonded medium. The bonded medium may be stored or shaped (8) under pressure to form agglomerates.

IPC: A23P10/30
Filed: 1998-05-28
Abstract: A novel formulation with improved resistance to the breakdown and loss of iodine from fortified food components, especially salt, has been developed. The salt formulation relies on the encapsulation of the iodine compound in a digestible, inert matrix that forms a physical barrier around the iodine compound, and thus prevents reaction of the iodine compound with other components in food, salt or atmosphere, which would otherwise lead to loss of iodine. An especially preferred embodiment is useful in the double--fortification of salt with iodine and iron.

IPC: A63F3/00
Filed: 1998-10-08
Abstract: A method of playing a poker-type game wherein the game provides the players an opportunity to increase the amount wagered based upon two of three community cards shown. After each player places a bet, two cards are dealt face down to each player and three cards are dealt face down to the dealer that are "community cards". The dealer then turns over two of the three community cards so that they are facing up. Each player has the opportunity to "double-down". The dealer then turns over the remaining community card and then turns over each player's two cards. The bets are resolved by using the three community cards in combination with each player's two cards based upon a predetermined plurality of winning card combinations similar to poker. The card deck is a standard 52 card deck with one joker to make a 53 card deck. The joker is utilized only in certain combinations as a 'wild card.'
