A drink station is provided with an alkaline filter cartridge in fluid communication with an ambient temperature water line provide alkaline water, and with a chilled water mixed with the alkaline water at a spigot to provide chilled alkaline water. A hot water heating element is located below the spigot so hot water flows upward for dispensing from the spigot, with a vent line between the heating element and spigot helping hot water to flow from the spigot to the heating element. A refrigeration system and a carbonation system is also provided. The refrigeration system uses the ice-bank technology. A submersible agitator pump improves heat exchanged between ice-bank and water by forced convection. The agitator pump operating based on the temperature of the drinking water. A figure eight evaporator coil can provide two cylindrical ice banks and two chilled water coils to increase the chilled water capacity.

An ice cream dipping cabinet which holds tubs of ice cream, is provided with individual tub receptacles, surrounded by cooling coils. The cabinet, which can be used for other foods, either frozen or cold, has a solid top plate which orients the individual tubs. This allows lower maintenance time and cost, helps keep moisture out and cold air in the enclosed bottom of the cabinet. The top plate has holes for the tubs, which limits the escape of cold air from the cabinet, improving energy efficiency, as well as improving the overall visual aesthetics of the cabinet, and the ease of access to the desired tub by the server. The invention also includes a locking device for preventing each tub from turning when being accessed in the proper serving position, and means for moving the tub upward for ease of removal. A clear cover has a slidable lid, which is slidable about an arc, and also pivotable upwardly for ease of removing and replacing the more remote tubs.

The present disclosure is directed to a micro-fluid ejection head for a micro-fluid ejection device. The head includes a semiconductor substrate, a fluid ejection actuator supported by the semiconductor substrate, a nozzle member containing nozzle holes attached to the substrate for expelling droplets of fluid from one or more nozzle holes in the nozzle member upon activation of the ejection actuator. The substrate further includes a thermal insulating barrier layer between the semiconductor substrate and the fluid ejection actuator. The thermal insulating barrier layer includes a porous, substantially impermeable material having a thermal conductivity of less than about 1 W / m-K.

The invention particularly relates to a foamed ceramic wall insulation material. The foamed ceramic wall insulation material is prepared from the following raw materials in weight fraction: 16%-20% of silicon carbide, 40%-45% of one or two of coal gangue or shale, 5%-8% of pulverized coal ash, 20%-25% of ore rock and 5%-7% of clay. According to the foamed ceramic wall insulation material, the thermal conduction efficiency is reduced and foamed ceramic has the characteristics of low heat transfer efficiency, excellent thermal shock resistance, reduced weight and the like, and is an ideal heat preservation and heat insulation material. The invention also provides a method for preparing the foamed ceramic wall insulation material by virtue of a physical reaction. Compared with the traditional chemical reaction process, the preparation method has the advantages that the process is more reasonable, the cost is reduced, no any radioactive material is generated in the production process, and thus the energy conservation and environment friendliness are achieved.

The invention provides a gas turbine blade that is capable of reducing the temperature difference between the pressure side and the suction side even if the trailing-edge cooling channel is narrow, thereby lessening thermal stress as well.A gas turbine blade 1 comprises: an internal trailing-edge cooling channel formed by a suction-side cooling target surface 6a and a pressure-side cooling target surface 6b that face each other; and multiple vortex-generator-shaped fins 10 disposed between the two cooling target surfaces 6a and 6b such that the fins 10 connect the two cooling target surfaces 6a and 6b. Each of the vortex-generator-shaped fins 10 includes an oblique surface 33 located on the downstream side of the flow direction of a cooling medium. A normal line 34 to the oblique surface 33 intersects with one of the two cooling target surfaces 6a and 6b.
