Abstract: The present invention relates to drinks dispense equipment having an ice dispensing capability. A drip tray is secured to such a dispenser and the drip tray has an electrical heating element secured directly to a bottom surface thereof. The heating element consists of a specialized printed circuit having a flexible plastic base having a positive temperature coefficient (PTC) electrical heating element printed on one surface thereof. The PTC element's resistance to the flow of electrical current decreases as its temperature decreases. Thus, the cooler the circuit the more current is allowed to flow there through, whereas the warmer the circuit the less current flows through the heating element thereof. In operation, as ice accumulates on the drip tray, the heating element is cooled causing an increase in the heat output thereof, thereby melting the ice. Once the ice has melted the heating element will reduce the flow of current as the temperature thereof warms to ambient.

Abstract: The present invention comprises a cart loading machine that provides for improved operating efficiencies, and includes a cart loading station, an infeed conveyor, a pattern forming area, a carrier sheet and wiping mechanism, and a fork loading apparatus. The cart loading station includes a framework defining a cart loading position and a cart waiting position. With the carrier in its extended position having carried a fully formed pattern to the cart loading position, a wiping mechanism is extended from beneath the carrier plate to contact the bundles as they sit on the carrier so that when the carrier moves back to its retracted position, the bundles are blocked and stripped therefrom. The wiping mechanism is then retracted below the carrier to permit the loading of a subsequent pattern of bundles thereon. This wiping mechanism eliminates the need for an overhanging blocking mechanism thereby permitting more efficient loader design and easier access to the pattern forming and bundle stripping areas.
