Abstract: Coffee filters formed by longitudinally spaced segments of a continuous tape of filter paper, connected by intact strips of said paper, the tape being rolled longitudinally to permit large numbers of said segments to be stored in a small space. The tape may be paid out from the roll and torn or otherwise separated from the tape for individual use. Each individual segment is provided with fold lines facilitating its formation into cup form, after separation from the tape, as required for use in most coffee making machines. Also provided is a dispenser container for the filter paper roll, the container being configurated to permit easy, one-at-a-time dispensing of the tape segments, and to prevent damage to the tape during dispensation.

Abstract: A hydroelectric device wherein a water wheel having radial paddle boards is partially submerged in a moving stream of water, and driven by the water current to operate an electric generator. The water wheel has end discs at its respective sides to block escape of water from between the paddle boards. The paddle boards are normally disposed at right angles to the current flow, but if the water current should flow faster at one side of the wheel than at the other, the ends of the boards at the slow-current side may be shifted forwardly, or the ends thereof at the fast-current side may be shifted rearwardly, having reference to the direction of current flow, in order that a portion of the water impinging against the fast-current ends of the boards will be deflected to the slow-current side. This adjustment may be made either by shifting the position of the wheel relative to the water bodily, or by shifting the paddle boards relative to the wheel.

Abstract: A lunch bucket having a food compartment and a separate, unconnected compartment for a beverage bottle, so that liquid possibly leaking from the bottle cannot damage the food, both compartments having closure doors, the bottle compartment door operating a friction device operable to secure said door frictionally in either its open or its closed position, and to secure the bottle in position when said door is closed.
