    Abstract: A pressure vacuum breaker cover assembly for protecting a vacuum breaker while simultaneously improving the appearance. The inventive device includes a pair of covers having a shell structure attachable to one another about a vacuum breaker. Each of the covers includes a lip that mates with the opposing cover lip, a plurality of apertures that allow the securing of the covers together with a conventional fastener, a lower cutout for receiving a lower pipe, and a side cutout for receiving an upper pipe from the vacuum breaker. The covers are preferably constructed of a STYROFOAM or polyfoam material for insulating and protecting the vacuum breaker and pipes. The exterior surface of the covers may be painted to match the exterior of the building structure.

    Abstract: The present invention is a post-mix beverage dispensing valve for accurately maintaining the proper ratio of two liquid beverage components. The present invention includes a valve main body having a gear pump secured thereto. The gear pump includes two sets of oval gears. One set of oval gears is in fluid communication with a source of pressurized carbonated water, and the second set is in fluid communication with a source of syrup. The valve body also includes solenoid operated pallet valves for each of the beverage components. Ratioing of the solenoid provides for simultaneous opening of both pallet valves whereby the pressurized carbonated water flows between the carbonated water gears and is swept thereby through the valve body to the dispensing nozzle. One gear of each gear pair is secured to a common rotating shaft. Pressurized carbonated water provides for the rotation of the syrup gears, thereby providing for the pumping of the syrup to the nozzle. The gear pairs are sized so that the desired ratio between the beverage components is maintained.

    Abstract: The present invention relates to regulators of cellular gene transcription, particularly inhibitors of cellular gene transactivating factors and in particular to inhibition of gene transcription in a viral host cell that is subject to regulation by proteins or factors that originate from a virus as well as conjugates or fusion products of the inhibitors and internalization molecules, pharmaceutical compositions that can be used to alleviate or prevent the manifestation of disease states that are the result of unregulated DNA transcription as a result of transactivation, methods of treating diseases that are caused or exacerbated by the presence of transactivating factors, and regulated gene therapy to achieve long term drug delivery of the inhibitors of the present invention. This invention can be applied both to cells with genetic abnormalities or to cells infected with a virus. Preferably, at least one protein of the protein-protein interactions is a transactivating factor.
