Abstract: A multiple-function beverage container opener is provided which features an ergonomically-shaped, elongate body having a stay-on tab opener on one end thereof, a crimped-on bottle cap opener on the opposite end thereof, and twist-off bottle opener in a central socket portion thereof. The stay-on tab opener is characterized by an arcuate loop formed between outboard and inboard arcuate-shaped lances. The arcuate-shaped lances and loop are provided with a radius that is substantially similar to the rim of the beverage container lid so that the loop fits between the tab handle and the rim of the beverage container. A ramp is coined in the arcuate loop to further assist in the camming of the tab handle upwardly into the arcuate loop for further pivoting and opening of the scored closure of the stay-on tab opener.

Abstract: A litter container is provided that is particularly adapted for use in urban environments. The litter container comprises an architecturally-styled, substantially cylindrical body which is bolted or otherwise suitably secured to a support surface. An arcuate door is disposed in the cylindrical body, the door comprising a substantially 180.degree. arcuate section of the cylindrical body. A hinge and mounting structure for the door is provided for pivotally mounting and cantilevering the door about a substantially vertical axis. The end of the door opposite the hinge is automatically locked in a closed or latched position by a tamper-proof latch which can only be actuated from the exterior of the litter container by a special key. A corrosion-resistant liner is disposed within the cylindrical body of the container and a chute centered on the axial centerline of the container communicates with the corrosion-resistant liner to direct litter therein.

Abstract: A method and solid-state electronic flowmeter with no moving parts is provided for monitoring instantaneous and/or accumulated fluid flow. A preferred application for the method and flowmeter is the measurement of the total volume of filtered fluid in a fluid treatment system as an indication of end of life for a filter therein. The flowmeter employs a solid-state transducer which senses differential pressure generated by a flow restriction such as a venturi which varies depending on a rate of flow. The transducer output in integrated over time to provide a representation of total fluid flow through the filter. The meter is preferably compact and battery-powered to facilitate ease of installation and use. Battery power is conserved by periodically energizing the transducer during idle periods and by periodically energizing the end of life indicator during and end of life condition.

Abstract: A double shell filter including an inner shell of bounded 80 to 400 U.S. mesh screen carbon particles and an outer shell of bonded 20 to 80 mesh screen carbon particles wherein the inner and outer particles are bonded internally to each other and the two shells are bonded together preferably by an ultra high molecular weight polymer binder having a melt index of less than about 1 gram per ten minutes as determined by ASTM D1238 at 190 degrees C. and 15 kilograms load.
