Abstract: A power monitoring system that reduces the need for transient voltage suppressors while using current transformers on an associated support operating using a current mode.

Abstract: A beverage dispenser for gravitationally dispensing a liquid from a bottle such as standard sized bottles commonly used in the drinking water industry. The dispenser preferably includes a removable top closeable over a space large enough to hold and fully enclose the inverted bottle, a base having a substantially flat bottom surface for maintaining the bottle in an inverted position and mating surfaces for receiving the removable top, a collar having an aperture sized to receive a neck portion of the bottle and disposed within the base for supporting the bottle in the inverted position, a reservoir attached to the collar for receiving the liquid from the bottle, whereby the neck portion of the inverted standard sized bottle extends downward through the aperture of the collar, and a spigot extending from the reservoir for dispensing the liquid from the reservoir.

Abstract: A device for removing calluses and dry skin is disclosed, including a base (2) with a rim (24) and support (30) for a block of pumice (15). Base (2) also has keyholes (8) and the pumice black (15) has receiving holes (16) to accommodate suction cups (20).

Abstract: A method of conducting a rapid microbiological assay of gases is disclosed that utilizes an improved gelatin membrane filter that is pre-filtered before casting to remove microscopic-sized particles.

Abstract: An internally plumbed housing for containing fluid purification media especially suitable for the production of ultrapure water. The device may be installed in a system for the production of laboratory grade water or may be used with pressurized feed for the delivery of purified water or other fluids in multiple applications.

Abstract: Devices suitable for adsorptive separation, filtration or catalytic conversion of liquid media are disclosed that have ideal dimensions for efficient performance. A method for dimensioning such devices is also disclosed.
