Abstract: In one embodiment, a filter media tower assembly is provided comprising a first portion and a second portion, wherein the first portion is suspended within the second portion. The first portion is a removable media tower or cage for holding filter media, whereas the second portion is a media tower guide support structure that is mounted to a surface of a tank. In a second embodiment, a load cell or a weighing assembly is disposed above the removable media tower. The deployment of this weighing mechanism above the removable media tower provides constant monitoring of biomass build-up on the filter media.

Abstract: A transformer for low-voltage applications such as landscape lighting, comprising a primary winding and a secondary winding inductively coupled to the primary winding, the primary winding adapted to be energized with a high voltage and the secondary winding adapted to carry a proportionately lower voltage, the secondary winding including a plurality of output taps, each output tap corresponding to a specified output voltage, and at least one common tap for each 300 W of output power up to the full capacity of the transformer, the secondary winding further including an additional common tap for an additional 300 W of output power beyond the full capacity of the transformer. A circuit breaker is associated with the primary winding and a circuit breaker is associated with each common tap and the additional common tap.

Abstract: A device for use in the manual sharpening of arrow broadheads, razor blades and the like includes a unique symmetrical clamp and axle assembly having interchangeable, matched pairs of special purpose jaw members for gripping blades of differing configurations. When coupled to the frame, the clamp and axle assembly is freely rotatable, and this free rotation automatically aligns the length of the edge of the blade with the surface of a whetstone. Additionally these rotational and self-aligning capability enable the user to service both sides of the blade's edge with a single blade clamping operation, by manually rotating the clamp 180 degrees between passes along the surface of the whetstone.

Abstract: A hat utilizing an internal means for securing items to the exterior of the hat. A preferred embodiment of the present invention is a baseball style cap with an internal means for attaching or securing sunglasses above the brim of the cap, where the sunglasses are readily secured by inserting the temples through slits in the cap. Because the securing means is internal, the hat maintains its overall aesthetic appearance. In one embodiment, the internal means for securing the eyeglasses or other object is an internal lining of a semi-rigid, but flexible material, such as buckram, neoprene or stretch fabric, with a corresponding slit in that material through which the article is inserted. In another embodiment, the internal means comprise of two strips of synthetic materials that adhere when pressed together, commonly sold under the trademark VELCRO™, affixed to each side of the slit opening.
