Abstract: A counter flow cooler in which feed material is fed into the top inlet of the cooler and dispersed into a plurality of cooling chambers. At the bottom of each cooling chamber is a discharge grid which will discharge feed material uniformly over the area of the cooling chamber. The discharge rate of this discharge grid can be adjusted to the desired throughput of the cooler. Air is drawn through the bottom of the discharge grid and passes up through the feed material in a counter flow manner. That is, while the product is passing down through the cooler, the air is passing up through the feed material, carrying away heat and possibly. A feed controller is used to selectively direct feed material into the plurality of cooling chambers. When a second batch of feed material is to be introduced into the cooler, feed material to the first cooling chamber is stopped and all the feed material is directed into the second cooling chamber.

Abstract: A material to be dried, such as a semiconductor substrate during manufacturing a semiconductor device, is loaded into a process chamber fitted at a loading opening with a lid which is closed from above. The inner side wall surface of the process chamber has a first surface formed in the lower part thereof and is substantially in parallel with the inner wall surface of the lid, and a second surface extending from the upper end part of the first surface and bent outwards to face the inner wall surface of the lid. A processing solution vapor is fed through a steam supply port in the second surface into the process chamber and flowed downwardly over the material to be dried. The processing solution vapor is condensed and recovered below the material to be dried.

Abstract: The present invention discloses a device and method for separating lint particles in a clothes dryer. In the present invention, the device and method use a cyclone to separate the lint particles. The cyclone includes a housing container having an inlet port and an outlet port. A screen is positioned about the inlet port. A tubing extends through the outlet port into the housing container. A drawing means draws moisture and lint laden air from the clothes dryer through the screen. A circulating means circulates the moisture and lint laden air in the housing container about the tubing. A removing means removes the moisture and lint laden air from the housing container and retains any lint particles within the housing container. The cyclone improves upon the efficiency of accumulating lint particles without compromising the passage of air flow in the exhaust duct and improves upon the passage of air flow without decreasing the amount of lint particles being trapped.

Abstract: Single or multi-screw indirect-heating screw conveyor desorbers having a heating gas guide enclosed by the screw shaft wall (single-wall screw shafts) or located between a screw shaft wall and an internal chamber wall (double-walled screw shafts). Predetermined amounts of cooling and diluting fluid may be added to a heating gas stream to control the maximum temperature thereof. Screw shaft support bearings and rotary drive components may be cooled, and conveyor wall and/or screw shaft surfaces (e.g.. screw flights and interflight surfaces) may be automatically cleaned during screw shaft rotation by hardened bits and/or breaker devices. Cleaning operations may also involve the interaction of two counter-rotating conveyor screw shafts having mutually interleaved and opposite-handed external flights.

Abstract: Apparatus for cooling strip includes a path of travel for the strip and cooling apparatus having a plurality of elongated gas nozzles within which are disposed water nozzles such that the water nozzles will have a discharge outlet within the gas nozzles and discharge water in generally the same direction as said gas discharge. In a preferred embodiment, the gas enshrouds the water and establishes a cocurrent two-fluid stream which impinges upon the strip moving by the cooling apparatus. Subsequently, heat transfer is enhanced by the air and water dynamics which are provided after impingement by fluid flow fields. The gas nozzles and water nozzles may be coaxial and in one embodiment are each circular. In one embodiment, containment gas is caused to impinge on the strip at a position longitudinally displaced from the regions of impingement of the cocurrent two-fluid stream on the strip so as to resist undesired flow of water.

Abstract: Air-blowing nozzles 21 for blowing a hot air are provided in both sides of an electrode sheet 33 for a battery both surfaces of which an electrode compounding agent has been applied to. In each of the air-blowing nozzles 21, a pair of slit-shaped blowholes 65 being extended in the width direction of the electrode sheet 33 are provided on both of the upper and lower sides of the end face part 63. The hot air blown off from a pair of the upper and lower blowholes 65 dries the electrode compounding agent as well as pressurizes a space between the electrode sheet 33 and the end face part 63 to form a pressure room P, and the left and right pressure rooms P hold the electrode sheet 33 to suppress its sway.

Abstract: A device for positioning a probe, such as a temperature sensor, in a flask for freeze drying. The device includes a stopper adapted to be secured to an open end of the flask. The stopper has a center opening and at least one radial opening spaced from the center opening. The radial opening allows for fluid communication between inside and outside of the flask when the stopper is secured to the open end of the flask. The center opening receives a guide tube which extends into the flask and is sized to receive the probe such that substantially no fluid communication between the inside of the flask and the outside of the flask occurs through the guide tube or center opening. A channel formed in an upper surface of the stopper and an O-ring positioned about an outer diameter of a neck of the flask secure the probe in position relative to the guide tube. The multiple radial openings define an annular passageway which mimics fluid communication through a standard slit-type stopper employed in freeze drying.

Abstract: In order to produce an optimally smooth paint surface in automobiles, the heating phase of the drying process is interrupted when an object temperature of about 65.degree. C. is reached. This object temperature is then held for at least two and at most three and a half minutes. Then the heating phase is continued until the holding temperature is reached.

Abstract: A steam blast box for applying steam to a web of paper conducted over a roll of a paper machine. The box has a closed steam blast chamber which extends along the roll transverse to the direction of travel of the web and to which steam can be fed. The front wall of the box, which faces the roll, has a plurality of steam outlet openings. A steam propagation space is formed between the front wall of the steam blast box and the roll. For controlling the temperature and/or for regulating the amount of heat transferred to the web of paper in the steam propagation space, an air outlet channel, which extends transverse to the direction of travel of the web and is located at the web inlet end of the steam propagation space, is provided for the admixing of air in the steam. In this way, sensitive separate, zone-wise control of the heating of the paper web can be obtained. The steam propagation space can be cooled zone-wise by feeding air on the inlet side.
