Abstract: A dryer monitor detects when textiles in a dryer are dry, detects when textiles in a dryer are overdry, and/or may count dryer cycles. The dryer monitor includes a humidity sensor, a temperature sensor, a controller and various status indicators.

Abstract: A method and apparatus for drying long fiber hay. A first step involves providing round bales of long fiber hay. A second step involves separating the bales to form a loose mass of long fiber hay. A third step involves feeding the loose mass of long fiber hay into a rotary dehydration drum. A fourth step involves separating the loose mass of long fiber hay from air containing entrained moisture by passing the long fiber hay through a cyclone separator with a first stream of air passing to an exhaust and a second stream of the loose mass of long fiber hay passing into an air lock. A fifth step involves cooling the loose mass of long fiber hay. A sixth step involves passing the loose mass of long fiber hay through a hay baler, whereby the loose mass of long fiber hay is formed back into bales.

Abstract: A universal building unit comprising a plurality of members connected to each other by at least one adjustable plate. There is also at least one panel connected to the plurality of members. In this case, the plurality of members, the adjustable plate, and the panels all connect together to form a universal building unit that can be repeatedly constructed and combined with adjacent building units to form a building structure. These building units also contain a heating and cooling system for heating and cooling each unit within the structure. In addition, these units can be combined in any manner to create stairs, walls, doors, fixed and movable partitions, windows, roofs, or any other type of building component. These building units comprise a series of simple, easy to install fittings and steel profiles to create framing for any type of building.

Abstract: A cooling system and method are provided for cooling a heater block located in a cylindrical processing chamber of a wafer processing apparatus. The cooling system includes first and second frame assemblies having respective ends adapted to rest on an upper peripheral surface of the processing chamber, and fan assemblies mounted to the frame assemblies at spaced locations therealong. A first pair of fan assemblies are directed to push air into the processing chamber, and a second pair of fan assemblies are directed to pull air out of the processing chamber. The fan assemblies are arranged such that they circulate ambient air through the processing chamber to provide a rapid cooling of the heater block to a safe working temperature. The frame assemblies have an adjustable length that can be adjusted to fit processing chambers having different sizes and configurations.

In another embodiment, one portion of a cooling stream from a cooling zone is vented, and another portion of the stream is passed to a drying zone.

Abstract: A method and apparatus for operating a dryer used to reduce the moisture content of sheet material such as a jet veneer dryer. A drying chamber is provided and includes a plurality of individual, juxtaposed drying sections. Each drying section circulates air in a path substantially transverse to the path of movement through the dryer. A single point exhaust system extracts the exhaust from the first drying section. A wet seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the wet seal section are a combination of ambient air drawn through restricted passages at the entry to the wet seal section and exhaust gas that bleeds into the wet seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential.

Abstract: Offal material, such as shrimp or crab shells, fish offal, etc, is dried to produce a fine-grained base material or additive for use in foodstuffs and animal fodder by subjecting a starting material in a chamber to a turbulent air current which accelerates the material lumps into various paths of movement. Hereby the material lumps continuously collide with each other, thereby constantly exposing new surfaces or rupture. The chamber is supplied with air, having a temperature which partly depends on the temperature of the starting material and partly depends on the comminution rate, in an amount adjusted according to the amount of starting material introduced per time unit. Hereby it is achieved that free water is immediately removed from the exposed surfaces of rupture by evaporation. By exerting a counter-pressure, the material is retained in the chamber until a desired particle size has been achieved.
