Abstract: A filter element designed for engine oil lubrication and hydraulic oils, comprising a core having a hollow interior and a perforated outer surface, in fluid communication with the hollow interior, an open first end in fluid communication with the hollow interior, and a closed second end. The filter element comprises alternately wrapping one or more layers of flat sheet barrier filter material and, on top of the barrier filter material, winding, in a uniform winding pattern, one or more layers of cotton/cellulose composition yarn over the outer surface of the core, each layer having a progressively finer filtration as the oil moves radially from the exterior of the element inward towards the core.

Abstract: A hot water dispensing system includes a water tank having a heat source for heating water in the tank. The tank has a cold water inlet and a hot water outlet. An expansion chamber is connected to the water tank and situated above the water tank for receiving heated water from the water tank.

Abstract: A hot water dispensing system includes a water tank having a heat source for heating water in the tank. The tank has a cold water inlet and a hot water outlet, and an expansion chamber is connected to the water tank. A faucet is connected to the hot water outlet of the tank. The faucet has an actuator for selectively dispensing hot water from the faucet as desired by a user. An aspirator is situated between the expansion chamber and the water tank, with an inlet coupled to the cold water inlet, an outlet communicating with the water tank and a vent opening in fluid communication with the expansion chamber. A flow control device is in fluid communication with the cold water inlet. The flow control device may be received in a pocket defined in the aspirator.

Abstract: A water chilling system includes a reservoir having an inlet and an outlet and a cooling device, such as a thermoelectric cooling probe, situated to cool water contained in the reservoir. A baffle is situated adjacent the inlet to direct water entering the reservoir to a predetermined area of the reservoir such the warmer water entering the reservoir does not immediately mix with the chilled water near the cooling probe.
