Abstract:
The present invention provides an automatic charging system of inflators into the thermally treating tower. The inflators 40 are conveyed inside a tubular passage 10 by a bucket 12 in an inflator conveying and discharging apparatus, and they are discharged into a first vertical passage 51 of an inflator charging apparatus. The inflators 40 are charged into a thermally treating tower 100 via a flat passage 53 and a second vertical passage 52.
Abstract:
The microfabricated cell injector having an injection wall and a cell injection needle projecting from the wall for piercing cells suspended in a fluid. The needle is held within a housing defined by the internal surfaces of the microfabricated cell injector. The housing has an inlet for suspended cells to enter and an outlet for cells to exit via the cell injection needle. A cell propulsion device is provided for impelling cells towards the needle such that, in use, cells suspended in the fluid are impelled towards the injection wall by the injection needle.
Abstract:
A flow distributor for mounting in an inlet of a heat exchanger includes a nose cone and one or more diverting rings. The nose cone is aerodynamically shaped to divert impingent gas flow around the nose cone. A first diverting ring is spaced outwardly from the nose cone and can be oriented such that at least a portion of the gas flow diverted by the nose cone is redirected into the wake of the nose cone. A second diverting ring can be spaced outwardly from the first diverting ring and can be oriented to divert gas flow impingent thereon. Struts connect the nose cone and one or more rings. Refractory on the wall of the inlet is shaped to reduce the recirculation at the outer perimeter thereof. The flow distributor is installed in the inlet with refractory to achieve substantially equal flow across the tube sheet of the heat exchanger.
Abstract:
The invention concerns a hollow needle axially mobile so as to pierce a container stopper. Said needle comprises a pointed end with a cutting edge tangent to the needle cylindrical body generatrix, an oblique shape linking the edge to said cylindrical body and a side outlet orifice of the channel centred on said generatrix and a site spaced from the edge, said orifice being centred perpendicular to the needle longitudinal axis. This invention is applicable to automatic and semiautomatic analytical equipment.
Abstract:
A medical infusion pump is disclosed which has a tube present sensor that determines the position of the tube within a pumping body. The tube present sensor having a pivotable sensor arm with a blade which engages the tube. The pivotable sensor arm having a sensor flag which actuates an optical switch to signal that the sensor arm is in engagement with the tube. The sensor exchanges positional information with a pump controller to affect operation of the pump.
Abstract:
The invention is for mixing at least one kind of an additive with a powdery or granular main material homogeneously so as to continuously supply the same quantitatively. A barrel comprises a front side cylindrical part, a trough part, and a rear side cylindrical part from the upstream side. A quantitative extruding zone comprises the front side cylindrical part and a quantitative extruding part having a full flight provided on the peripheral surface of the axis part of a screw, for quantitatively transporting a main material to the downstream side. A mixing zone comprises the trough part and a mixing part having an agitating blade formed zigzag on the axis part of the screw and a ribbon screw having a distance with respect to the peripheral surface of the axis part, for homogeneously dispersing additives added from additive supply openings in the main material. The scraping out zone comprises the rear side cylindrical part and a scraping out part having forward paddles and backward paddles formed alternately on the peripheral surface of the axis part of the screw, for discharging the mixture from a discharge opening.
Abstract:
In a method and apparatus for producing a vapor which serves as a chemical processing material by delivering a carrier gas and a reactive liquid to a vaporizer in which the vapor is produced, the operating state of the vaporizer is monitored by measuring the pressure of the carrier gas being delivered to the vaporizer and producing a detectable indication when the measured pressure exceeds a given value.
Abstract:
A showerhead for introducing gas from one or more external supplies into a substrate processing chamber, the showerhead including a faceplate including a plurality of gas injection ports through which gas is injected into the chamber, wherein the plurality of gas injection ports includes a first subset of gas injection ports and a second subset of gas injection ports; a first gas distribution system which during use delivers a first gas to the first subset of injection ports for injection into the chamber; and a second gas distribution system which during use delivers a second gas to the second subset of injection ports for injection into the chamber.
Abstract:
An ozone supplying apparatus comprising an ozone generator, an adsorption/desorption device for adsorbing and storing ozone from ozonized oxygen, and an ozone desorbing means, the apparatus being arranged to return oxygen to the ozone generator after desorbing ozone therefrom to desorb ozone from the adsorption/desorption device and to perform treatment of an object by mixing the ozone with fluid. The apparatus further includes a fluid storing means for storing fluid after being injected with ozone and a fluid treating means for treating the fluid after treatment of the object.
Abstract:
An apparatus for sampling and draining media from a vessel or reactor is described. The apparatus comprises: (a) a valve body with a generally longitudinal axis extending therethrough; (b) a moveable disc assembly positioned within a central channel of the valve body; (c) a valve operating rod extending within the valve body along its longitudinal axis; (d) a piston actuator assembly for positioning the disc assembly along the central channel; and (e) a sampling port extending away from the valve body. The valve body comprises the central channel, which has an upper end communicable with a port in the wall of the vessel or reactor and a side outlet which extends away from the longitudinal axis of the valve body. The valve operating rod has an upper end which is communicable with the disc assembly. The piston actuator assembly is communicable with an opposite, lower end of the valve operating rod.
