Abstract: A system for drying microelectronic, optical and other parts which are rendered wet in the course of their processing, the system functioning rapidly to dry these parts so that they are free of contaminants. The system includes a drying chamber having a work zone in which the wet parts are held in a removable carrier resting on a stand, the work zone being heated to promote evaporation. Flowing through the work zone and passing over the wet parts is a gaseous stream which entrains vapors emitted from the parts and discharges the vapors from the chamber. To accelerate the evaporative process, a vibration generator is operatively coupled to the stand or to a vibration coupling device to impart vibrations thereto which are transmitted to the wet parts in the carrier, causing liquid drops on the surfaces of the parts to fractionate into droplets or to otherwise disperse and spread the liquid over a larger area, thereby greatly increasing the aggregate exposed surface area of the liquid.

Abstract: A process for manufacturing a high bulk density particulate detergent composition, of a bulk density greater than 0.7 g./cc. and preferably in the range of 0.8 to 1.0 g./cc., includes turbodrying a mixture of synthetic anionic organic detergent, preferably of sodium C.sub.12-13 linear alkylbenzene sulfonate, water, and fabric softening bentonite, in which turbodrying process the mixture is repeatedly subjected to centrifugal and axial forces which create thin films of the mixture, which are pulled apart, due to such forces, to form particles, which are further turbodried and thereby converted to high bulk density particles of substantially globular shape and desired particle sizes. In a preferred embodiment of the invention the mixture charged to the turbodryer is made by turbomixing and aqueous solution, dispersion or paste of anionic detergent with bentonite, and the mixture made thereby is directly turbodried.

Abstract: A steam shower apparatus and method including a supply of steam which is fed through a Coanda nozzle and along a path running adjacent one surface of the apparatus which is heated to a temperature in excess of 175-180 degrees Fahrenheit.

The flow of steam runs the entire length of this surface heating the sheet as it flows in the opposite direction. The apparatus may be divided into several sections so that the sheet may be profiled along certain regions which are defined by these sections.

Abstract: Flat structural components such as sheetrock panels are dried sequentially by two different drying methods and devices. The first drying is performed as a convection drying, whereby surface layers of the panels are dried. The second drying is performed by a high frequency drying, whereby a still moist central core layer is dried down to a desired remainder moisture content. During the second drying by a high frequency generator, the moisture is driven out by diffusion, whereby any over-drying of outer surface layers is reversed again so that any over-drying, or rather damages that may be caused by dehydration of the gypsum in the sheetrock panels is repaired again since the outwardly diffusion moisture enables the gypsum to cure and set again.
