Patent CA-2438839-A1 (CA)
Title: Vacuum cleaner with continuous liquid pick-up
Inventor: KNAUFF VINCENT
IPC: A47L7/00
Filed: 2003-08-28
Abstract: The disclosed vacuum cleaner can continuously collect liquid while periodically discharging liquid from an outlet. It has a tank with two chambers divided by an intermediate wall with an aperture. One chamber is vented to the atmosphere, and has an outlet with a pressure--responsive drain valve that closes when a partial vacuum is present and opens when the partial vacuum is reduced and liquid in the chamber presses on the drain valve. The aperture has a pressure-responsive control valve that closes when the liquid level in the second chamber is high, so that liquid collects in the first chamber while the vent reduces the partial vacuum level, thereby discharging liquid through the outlet. A reset assembly can re-establish a partial vacuum level to close the drain valve and open the control valve.

Title: Circuit and method for providing an auto-off capability for a wireless transmitter
Inventor: COHEN ARTHUR L
IPC: G05F1/10
Filed: 2004-01-09
Abstract: The invention is a circuit and method for providing an auto-off capability for a wireless transmitter, of a type having an audio plug which mates with the output jack of an audio source. The portable transmitter modulates audio signals from the audio source onto a carrier and transmits them to a receiver. The auto-off capability is provided to prolong battery life and degradation of the transmitter circuit and comprises pinching off a FET when the circuit is in an "off" state. This occurs when a pre-determined threshold in a capacitor is reached by not discharging that capacitor. The capacitor is discharged by dropping an input to a comparator below a pre- determined threshold limit when presented with an audio peak and wherein the drop in value causes the comparator output to discharge the capacitor and causing the FET to supply power to the regulator.

Title: Gaming apparatus and method
Inventor: MOSHAL MARTIN
IPC: G07F17/32
Filed: 2002-09-19
Abstract: A gaming apparatus comprises a server and a client computer, each operating under stored program control and in communication with each other by means of a communication network. The client computer is usable by a player to place a wager on an outcome of a particular spin of a roulette wheel, as well as a side ager on a combined outcome of the particular spin of the roulette wheel and one or more immediately preceding spins of the wheel. A portion of each side wager is accumulated in a pooled jackpot. Once the wagers have been placed, the gaming server randomly selects the outcome of the particular spin of the roulette wheel, and evaluates the success, or otherwise, of the side wager. The side wager is successful if the outcomes of the particular spin of the roulette wheel, and the immediately preceding spins are identical. The outcome of the particular spin of the roulette wheel and the success, or otherwise, of the side wager are transmitted by the gaming server along the communication network to the client computer for display to the player. A  successful side wager wins for the player the accumulated contents of the pooled jackpot.

Title: Idiom recognizing document splitter
Inventor: KLASSEN R VICTOR
IPC: G06F3/12
Filed: 2004-03-29
Abstract: A method and system is provided for splitting a print job lacking page independence into selected job portions wherein the job portions can be independently processed in a plurality of processing nodes into a printer dependent format for printing by a printer. The print job is searched for selected tokens/idioms known to normally generate a fault upon the independent processing if the print job were to be split into the selected job portions that were intended to be handled independently. The selected tokens found in the search are saved. The print job is then split into the selected portions and the tokens are then associated with the split job portions for guaranteeing processing independence during the processing by the processing nodes.

Abstract: The object of this invention is to provide a curling iron using heated fluid as its heat source for heating hair. The curling iron of the present invention is comprised of a fluid heating unit which heats the fluid to produce steam (100) used as the heat source, a heating unit which transfers heat of the steam to hair, and thereby curls the hair, and curling tongs which support the heating unit so as to allow the heating unit to heat the hair while the curling tongs grasp the hair. Since the curling iron uses heated fluid as its heat source for heating hair, the curling iron uses heated fluid as its heat source for heating hair, the curling iron maintains a constant temperature capable of accomplishing a desired curling effect and prevents an excessive increase in its temperature so as to prevent damage to the hair.
