A wet work is heated by immersion in the hot D.I. water bath and then lifted up to drain and dry same.

Abstract: An apparatus for drying a web of roll material has two rows of comparatively low and high temperature cylinders, and a metal belt and a felt belt entrained in parallel for transporting the web on a serpentine path around the cylinders. The metal belt is pre-heated at an input side to each low temperature cylinder to a temperature from 140.degree. C. to 170.degree. C. An input press roll applies a nip pressure to the metal belt against the web, felt belt, and low temperature cylinder from 60 to 200 pli (pounds per linear inch). The surface of the low temperature cylinder is heated to an intermediate temperature from 100.degree. C. to 140.degree. C. The temperature of the heated belt at an input side is maintained only about 20.degree. C. higher than that of the low temperature cylinder. The low temperature cylinder has air pressure grooves for maintaining a negative air pressure in the range of 0.1 to 0.7 bar at its surface for lowering the vapor pressure for water evaporated from the web.

Abstract: A control system for a clothes dryer is disclosed. A microprocessor monitors the heated inlet air temperature and the exhaust temperature. If the inlet temperature exceeds a high limit value a given number of times, an air blockage indicator is activated. Degrees of dryness are measured by the number of times the inlet temperature has dropped below a threshold value while the heater is off because the exhaust temperature has exceeded a desired value. An estimated drying time is calculated and displayed to the user based on a linear function of the inlet and exhaust temperatures measured at the beginning of the cycle and again a short time later.

Abstract: This invention relates to a heated steam atmosphere drying system comprising dryer in combination with an exhaust recompression system which is extremely energy efficient and eliminates dangers known to air dryers. The system uses superheated steam as the drying medium, which recirculated through the system where its heat of evaporation and heat of compression is recovered, thereby providing a constant source of heat to the drying chamber. The dryer has inlets whereby feedstock and superheated steam are fed therein. High heat transfer and drying rates are achieved by intimate contact of the superheated steam with the particles being dried The dryer comprises a vessel which enables the feedstock and steam to enter recirculate together. When the feedstock becomes dry it will exit the dryer with the steam and become separated from the steam through the use of a curvilinear louver separator (CLS). The CLS enables removal of fine and ultrafine particles from the dryer.

Abstract: A display formed of two colorless, transparent plastic cylinders mounted concentrically with a vertical axis upon a base. The space between the two cylinders forms a tank which is filled with liquid and some plastic snowflakes having a slightly greater specific gravity than the liquid. An object to be displayed is positioned within the inner cylinder and, so, is not in contact with the liquid. The object and the liquid are illuminated by a light within the base. A motor operates a pump having an uncased spiral rotor projecting vertically downwardly into the liquid. Rotation of the pump causes a diffuse upward flow of the liquid and the snowflakes in the vicinity of the pump. Though this causes the snowflakes to move upwardly in a gentle and diffuse manner, this motion isn't particularly noticed by an observer. When the snowflakes reach the top of the liquid, they are diffused sidewardly and begin dropping, creating a snowfall effect.

Abstract: A hydraulic drive system has a consumer of hydraulic power connected to a pressure medium source, e.g., a hydraulic motor 1. The consumer can be actuated by a control valve 4 throttling in intermediate positions; its width of opening is determined by a pressure difference formed at the control valve 4. The pressure difference is derived from a control pressure to be prescribed and the load pressure of the consumer. The consumer can thus be driven with a definite power or a definite torque. To limit the movement speed of the consumer, it is proposed to reduce the control pressure as a function of the speed of movement. The control pressure is present in a control pressure line 7 or 8, which empty at a charging space of the control valve 4, active in the opening direction. A drain line 16 branches from the control pressure line 7 or 8, in which a multiway valve spring-loaded in the closing direction and throttling in intermediate positions is located.
