Abstract:
An improved cleaning composition and method adapted to clean a variety of hard surfaces. The improved cleaning composition and method includes the use of a cationic biocide that includes biguanide compounds and/or quats.
Abstract:
The present invention relates to disinfecting wipes or pads that can be use to treat or clean glass or other glossy surfaces. The disinfecting wipes or pads do not depend upon quaternary ammonium compounds for disinfection, but instead depend upon relatively low solvent levels and basic pH or relatively high levels of sodium hydroxide or potassium hydroxide.
Abstract:
An implement for coupling to and effecting remote manual manipulation of an object. The inventive device includes a handle tube having a plurality of extension tubes telescopingly received within the handle tube. An engaging clip is secured to an outermost extension tube for engaging an object for manipulation by an individual holding the handle tube.
Abstract:
A colorless tunable optical dispersion compensator (TODC) comprising a silica arrayed-waveguide grating (AWG) directly coupled to a polymer thermo-optic lens. As a result of its inventive construction, the device exhibits low loss, large tuning range, low electrical consumption and is readily manufactured using standard processes. Additionally, the TODC is fully solid-state and scales to a large figure-of-merit (dispersion range times bandwidth squared).
Abstract:
A magnifying apparatus removably attached to a menu, check wallet, billfold, wine list, and the like. The magnifying apparatus includes illumination means to illuminate an area viewed using the magnifying apparatus. The magnifying element may be a fresnel lens. The fresnel lens preferably has a power of 2-4 times. However, a magnification of up to 9 times or more can be used. The magnifying element may also be a standard lens preferably having a high index of refraction. It is preferable to have a high index of refraction to minimize the thickness of the lens. The standard lens or the fresnel lens is plastic, glass, polycarbon, or the like. Electronic magnification and display means may also be used.

Abstract:
An energy efficient water purification system which maintains critical operating temperatures for effective reverse osmosis. The system includes hot and cold water inlets providing a flow of heated feed water, a regeneratable pre-treatment system for treating the heated feed water, a reverse osmosis machine for receiving the flow of pre-treated feed water heated to a given temperature to purify the feed water and discharge impurities in a discharge stream and feed the purified feed water to an outlet for end use, and a valve to control the temperature of the heated feed water entering the pre-treatment system, and an energy conserving apparatus comprising a valve arrangement which interrupts the heated water flow into the pre-treatment system and substitutes fresh unheated feed water during regeneration.
