Disclosed is system, method, and rack stand portion for the advantageous cooling of computer equipment 305. The rack stand 200 includes a hollow body 210, 212 that may be formed of cartridges 2416. Gas from an airflow source 5204 is guided into the rack stand body and then into a sealed case of the computer equipment. Air flow is then guided out of the computer equipment for recirculation, exhaust, or other purpose.

A shutter valve for regulating pressure and controlling fluid flow comprising: an actuator ring comprising a plurality of gear teeth, the gear teeth driven by a mating gear; a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, each arm pin boss further comprising a hinge pin aperture; three or more pivot arms, each pivot arm having a first end and a second end, the first end forming a hinge and mounted to a hinge pin aperture of an arm pin boss; three or more obturator elements; and a housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements.
摘要:
The invention relates to a device for regulating the chamber pressure of coking chambers of a coke-oven battery using adjustable iris diaphragms or iris nozzles at the ascending pipe elbow openings in the raw gas receiver. The gas stream flowing from the gas chamber of a coking chamber into the raw gas receiver can thus be regulated in permeability so that the pressure in the gas chamber of the coking chamber can be regulated. The invention also relates to a method for regulating the gas stream which flows out the gas chamber of a coking chamber, wherein the pressure in the coking chamber is regulated by said control, and wherein also the liquid stream is regulated which serves to wash out the coking gases from the raw gas stream of the coking chamber.
摘要:
A vapor compression system (10) having a line (19) for flowing heat transfer fluid (34), a compressor (12) and a condenser (14) both connected with the line (19). The vapor compression system (10) also has an expansion device (18) connected with the line (19) for expanding the heat transfer fluid (34). The expansion device (18) has a housing (40) defining an orifice (44, 46, 62, 66, 74, 76) with at least two positions, wherein the orifice is effectively made larger in the first position than in the second position. The vapor compression system (10) also has an evaporator (16) connected with the line (19) for transferring heat from ambient surroundings to the heat transfer fluid (34).

A weighing machine includes at least one hopper, said hopper having a tubular body (11) with closing means (15) located adjacent its lower end. The closing means (15) selectively opens and closes the lower end of the tubular body and comprises a plurality of plates (16) pivotally mounted for movement in a plane transverse to the axis of the tubular body. This pivotal movement is between a closed position, in which the plates engage one another generally centrally of the bore of the tubular body and an open position, in which the plates are disposed clear of the bore of the tubular body. Means (30) are provided to drive the plates between their open and closed positions.
摘要:
A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes a plurality of blades disposed about the air inlet and each pivotable about one end of the blade, the blades extending through a slot in the air inlet wall when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates.
摘要:
Apparatus for blocking the bore of a pipe (1) comprises a plurality of elongate shutter members (15-17) pivotably mounted to an elongate support member (3/3a) for insertion through a pre-drilled aperture (8) in the pipe wall. Actuating means (14) are provided for pivoting the shutter members (15-17) from an insertion configuration in which they are substantially aligned with said support member (3a) and a deployed configuration in which they are fanned out across the bore of the pipe (1). Each shutter member (15-17) is pivoted about a point (9) located towards one end thereof and towards the insertion end of the support member (3a) so as in use to lie between the axis of the bore of the pipe and the wall of the pipe (1) opposite the location of said aperture.
