    摘要： Cephamycin compounds of the formula (I) ##STR1## wherein R.sup.1 represents hydroxyl or sulphooxy and R.sup.2 represents sulphooxy together with derivatives thereof including salts, esters, N-protected derivatives and solvates thereof are disclosed. These compounds are of great value as intermediates in the preparation of other cephamycin compounds.The compounds of the invention may be isolated from fermentation broths of strains of the genus Streptomyces which produce the compounds and a new such strain is described. The isolation of the compounds may be achieved by a liquid/liquid or liquid/solid ion-exchange technique, and is preferably achieved by the formation of an ion-pair in a liquid/liquid technique.

    摘要： A trailer marker system including side markers and a round marker is disclosed herein. The side markers are to extend along the side of a trailer or trailer vehicle. The side markers are elongated lights, while the round marker is a circular shaped light. The side markers and round marker illuminate the surroundings of a trailer vehicle for increased safety. Importantly, each of the side markers and rear marker include lights that face down towards the roadway. This results in road markings being illuminated as to allow a driver of the trailer vehicles to safely remain on the road. Additionally, the downward facing lights found in the side markers and the rear marker help to eliminate blind spots. Blind spots when making a turn or reversing the trailer are eliminated as they are illuminated in order to allow the driver to be safer when operating the trailer vehicle.

    摘要： The present invention discloses a method and device for dispersing powders and, in particular, to a method of dispersing inhaling powders in which a powder is positioned in a passage wherein the passage has one or more exits, one or more inlets and one or more obstructions to block the movement or to contain the powder within the device before use, whereupon a breaching pressure differential between the one or more exits and the one or more inlets of the passage is applied to breach the one or more obstructions so as to generate a flow through the passage which fully or partially aerosolizes the powder by means of the generated flow thus releasing a fully or partially aerosolized powder from the device.

    摘要： An improved HVAC system is provided for the delivery of a temperature controlled air supply via one or more air curtains provided at windows, doors and walls. The air curtains create a double layer of insulation over the surface of a window, door or wall. The invention provides for the use of the temperature controlled air flow from the air curtain to directly affect the interior room temperature. The invention provides an improved system for continuous cleaning the recycled air through the use of a wet electrostatic precipitator in the HVAC air flow, as well as providing a higher speed mode for the air curtain to prevent the inflow of particles and contaminants from outside of the building, when windows or doors are open. The invention may be installed on existing construction, or incorporated as part of new construction.
