  • Publication number: 20190263051
    Abstract: An apparatus and method for generating a three-dimensional object. The apparatus includes a build material area, at least one agent distributor with a fluid reservoir to store fluid agent and at least one fluid ejection die to selectively eject fluid agent in the build material area. A cooling system to remove heat from the at least one fluid ejection die has a heat sink. The at least one fluid ejection die is in thermal contact with the heat sink via the fluid agent of the fluid reservoir.

  • Publication number: 20110039293
    Abstract: The present invention is related to the medicine field. Specifically, the present Invention is related with an effervescent solid pharmaceutical composition of dextrose having as purpose determining the metabolized glucose levels in a patient with diabetes or glucose metabolism related conditions, in a simple and effective manner with respect to the conventional products of this kind. Accordingly, the present invention provides a novel product allowing the medical professional or physician of a clinic laboratory to determine in a quantitative, economic, efficient, fast and in a single manner, the clinical conditions of a patient regarding the glucose level and the pancreas ability to eliminate the unnecessary sugars in terms of time. Furthermore, the present invention provides a novel process for preparing the novel effervescent solid pharmaceutical formulation of dextrose.

  • Patent number: 5808871
    Abstract: A modular tower having a plurality of bays. The bays are fitted with rails upon which individual trays slide. The trays are detailed to carry electronic components. Each tray is fitted with electrical connectors which are connected to corresponding electrical connectors on a backplane in the tower. The tower can be employed vertically and horizontally. The tower has easily removable top and side panels and has a two component base that may be adjustably secured to one or more of the towers. The front thereof is fitted with a removable frame which carries a hinged door. The frame can be removed and rotated 180.degree. in order to change the swing of the door from left to right and vice-versa.
