Abstract: In a method for controlling a freeze drying process, a frozen product is arranged on temperature controlled surfaces (12) in an air-evacuated chamber (1) and undergoes a main drying and after-drying phase. During the main drying phase, the temperature of the ice surrounding said product is continuously measured. The pressure in the chamber and/or the temperature of the surfaces are modified during transition from the main drying phase to the after-drying phase. In order to avoid longer idle periods between the chamber (1) and the evacuation device (3, 4, 14) and to determine transition from the main drying phase to the after-drying phase, the pressure and/or the temperature of the surfaces during said transition are modified according to changes int he temperature of the ice.

Abstract: A method and apparatus is provided for continuous dehydration of sludge wherein, prior to dehydration, water is mechanically removed from the sludge, and the thus obtained sludge of cutting consistency is mixed with heated spheres. Dehydration is carried out at reduced pressure, wherein the sludge from which water has been mechanically removed is intimately mixed with the heated spheres in order to increase the heat capacity of the sludge. The dehydrated sludge and the cooled spheres are then separated from each other, the dehydrated sludge is removed, while the cooled spheres are reheated and subsequently added to fresh sludge that is to be dehydrated. The spheres are partly heated by means of water vapor coming from the sludge and partly by means of steam. The spheres are made from steel, having a diameter of 8-16 mm. The pressure in the system ranges form approx. 2 bars to approx. 0.05 bar. An apparatus is also provided for carrying out the method.

Abstract: A method and apparatus for drying material, especially wood particles, having moisture therein, comprising depositing the material to a selected depth onto a transport conveyor at the first end of a drying chamber.

Means are provided adjacent the second end for removing the second layer, which has the desired moisture, from the conveyor and directing that layer exteriorly of the chamber. The first layer, which has a remaining moisture content greater than the first layer, may be further dried to achieve the desired moisture content.

Abstract: In its simplest conceptual form, the applicant's invention is the structure of a conventional shoe sole that has been modified by having its sides bent up so that their inner surface conforms to a shape nearly identical but slightly smaller than the shape of the outer surface of the sides of the foot sole of the wearer (instead of the shoe sole sides conforming to the ground by paralleling it, as is conventional). The shoe sole sides are sufficiently flexible to bend out easily when the shoes are put on the wearer's feet and therefore the shoe soles gently hold the sides of the wearer's foot sole when on, providing the equivalent of custom fit in a mass-produced shoe sole. This invention can be applied to shoe sole structures based on a theoretically ideal stability plane as a basic concept, especially including structures exceeding that plane.
