Abstract: A filter element 28 for a gravity-flow water filter. An inlet screen 44 divides a cylinder 48 into two functionally distinct portions, an overflow chamber 24, and a filter body 26 which contains a filter medium 54. A wire half-loop 16 suspends overflow chamber 24 from an adjustable water source and positions overflow chamber 24 to catch the water outflow from the source. Wire half-loop 16 also positions overflow chamber 24 at a distance from the source so that there is a gap 22 between overflow chamber 24 and the source. The potential for water rising and spilling from overflow chamber 24 induces a user to adjust the source flow to less than a characteristic rate. When the flow is adjusted so that water level in overflow chamber 24 is not rising, the water level continues dropping until the flow of water from the source continuously enters the screened entrance of filter body 26 with no appreciable pressure head.

Abstract: A device that reclaims industrial fluids. Solid contaminants are removed from the liquid being reclaimed by a series of increasingly fine filter elements positioned within a filter housing. The substantially solid contaminant-free fluid then enters an evaporation chamber having a design that constrains the fluid to form a thin film atop an evaporation plate at the bottom of the chamber to facilitate evaporation of volatile contaminants. Insert members are positioned within the evaporation chamber to increase the surface area of the thin film to further enhance the removal of the volatile contaminants. The temperature and pressure of the evaporation chamber is controlled by a heating element that is under the control of a temperature sensor. Evaporated volatile contaminants escape the evaporation chamber through a port formed in the head that closes the device. Latches are used to secure the head in the absence of conventional nuts and bolts, and the head screw threadedly engages the evaporation plate.

Abstract: A totally enclosed fuel oil filter housing having a fuel inlet nipple and a fuel outlet nipple is assembled on a mounting bracket with the nipples extending through hexagonal apertures in the mounting bracket. The inlet and outlet nipples are threaded to couple connecting fuel lines and are of different sizes to prevent a reversal of the connections. The nipples have hexagonal peripheries which mate the apertures so that torsional forces during coupling are transmitted to the bracket rather than to the seals between the nipples and the filter housing, and the apertures of the mounting bracket are formed by being drawn out of the plane of the base of the mounting bracket to project therefrom. The side walls of the housing has inwardly directed ribs and a bead of sealant spans each rib to localize the pressure between the side walls of the housing and the accordion pleated filter medium through the sealant bead to assure a void-free seal therebetween.

Mounted upon a power unit is a motor having an output shaft which at one end is provided with a magnet. The power unit and filter unit are both hung from the rim of a wall of the aquarium by means of interlocking lip structures. The units are constructed such that the filter unit is seated in a "nesting" fashion upon the power unit, thus the power unit and filter unit are positioned in close proximity to one another and maintained in proper alignment such that the magnetic field of the magnet on the motor shaft magnetically influences a flywheel of the water pump and causes the latter to pump water when the motor is energized.
