Title: Fish'n fun-nel
Inventor: GAUNE KENNETH J A
IPC: A63F9/34
Filed: 2003-07-15
Abstract: The invention is a device that provides a unique opportunity for a person(s) with a fishing rod and casting reel to cast into a specifically defined target.    Instead of casting a fishing lure, the lure is replaced with a magnet. When the magnet lands in The "Fish'n Fun-nel" it is naturally directed to the center of the funnel and down into the funnel tube. The funnel tube is closed at the bottom and holds round metal tokens stacked on top of each other. The tokens are only a fraction smaller in circumference than the inside circumference of the tube. Therefore the magnet always attaches to the top token only. The person(s) or player(s) then reels in the token. The token has a symbol on it which represents one of the symbols needed to win that particular game being played.    The tokens are loaded in the funnel tube in random order. Different sets of tokens represent different games.

Abstract: One aspect of the present invention relates to a method for the kinetic resolution of racemic and diastereomeric mixtures of chiral compounds. The critical elements of the method are: a non-racemic chiral tertiary-amine-containing catalyst; a racemic or diastereomeric mixture of a chiral substrate, e.g., a cyclic carbonate or cyclic carbamate; and a nucleophile, e.g., an alcohol, amine or thiol. A preferred embodiment of the present invention relates to a method for achieving the kinetic resolution of racemic and diastereomeric mixtures of derivatives of -and- amino, hydroxy, and thio carboxylic acids. In certain embodiments, the methods of the present invention achieve dynamic kinetic resolution of a racemic or diastereomeric mixture of a substrate, i.e., a kinetic resolution wherein the yield of the resolved enantiomer or diastereomer, respectively, exceeds the amount present in the original mixture due to the in situ equilibration of the enantiomers or diastereomers under the reaction conditions prior to the resolution step.

Abstract: The present invention relates to the field of e-commerce and in particular to making purchases on-line using payment card, for example debit, charge or credit cards. The concept of the present invention adopts an alternative approach to security methods presently employed to protect cardholders. The concept obviates the need for a cardholder to transmit Card Numbers along with other purchasing details at the time of purchase and couples this with the use of a password feature. This renders the transaction akin to a Bank Cash withdrawal that Bank/card Schemes are totally happy with from a security point of view but are reluctant to allow e-commerce and/or any others access to their "network" to ensure Security.

Abstract: With small, generally residential heating systems, it is common to use a single forced-air furnace for heating and cooling of all levels. The basement is normally provided with supply air from the furnace, which is distributed to the space from ceiling diffusers. The result is that the area where the furnace thermostat is located (normally the main floor) is comfortable but the basement is warm at ceiling level and uncomfortably cool at floor level. The invention that we have devised provides a means of effectively heating a basement (or other) floor, wall or ceiling slab using a conventional forced air furnace as the heat source.
