Abstract: A coffee and/or tea disperser having a cold water reservoir connected to a water heater which is connected in turn to a spray head. Below the head is a container for a bed of coffee grains or tea leaves and below which again is a tank for the infused beverage. Cups of freshly infused coffee or tea can be metered from the tank by a dispensing valve. In order to ensure that the amount of coffee dispensed does not vary by any significant amount as the head of liquid in the tank varies, the tank is disposed above the surface on which the cup rests by a distance, measured from the maximum head of liquid in the tank to said datum, which is at least six times the maximum displacement of liquid in the tank. Moreover the tank is wide and low. The tank is preferably dismountable for easy cleaning and level probes normally protruding into the tank are arranged to be swung out of the tank to assist dismounting.

Abstract: A method of playing a bowling game in which players are allowed at least one ball to knock down pins in each of a plurality of frames. A handicap is determined for each player of the game. A handicap pin setup is selected for each player for each frame commensurate with the respective player's handicap. Each player is required to deliver at least one ball in each frame. The number of pins knocked down by each player in each frame is counted to determine a score for each player for each frame. Each player's frame score is recorded as determined by the counting, and each player's frame scores are added to determine the player's total score for the game. The players' game scores are compared to determine the winner of the game.
