Abstract: In order to provide a treatment installation for treating workpieces that is of simple construction and enables optimised workpiece treatment, it is proposed that the treatment installation should include a treatment chamber and a conveying device, by means of which the workpieces are suppliable to the treatment chamber, are removable from the treatment chamber, and/or are conveyable through the treatment chamber in a conveying direction.

Abstract: Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.

Abstract: A method for drying a wet material, which comprises a liquid Fd to be distilled, uses a gas-tight container system resistant to excess and/or negative pressure and a drying container, a condenser and a vapor chamber connecting the drying container and condenser. The temperature adjustable drying container contains the wet material. The liquid Fd is turned to vapor in the temperature adjustable vapor chamber. The condenser condenses the vapor to give the condensation product. The pressure in the vapor chamber is monitored and controlled so that drying and distillation are always carried out in a range close to the saturation vapor pressure of the liquid Fd to be distilled. The pressure and the temperature in the vapor chamber are continuously determined. If the pressure goes above the upper limit of the range, the pressure is reduced in such a manner that especially foreign gas is removed.

Abstract: A centralized device for the distribution and discharge of air causing the evaporation of a carrier in a number of user installations each having an intake channel and a discharge channel, comprising a single manifold for the reception, delivery and discharge of air-carrier mixture from and to the installations and a discharge fan connected to said manifold, and comprising for each installation: a device for air supply, connected to the single manifold and having a fresh air suction channel and an air supply channel, a fan connected to the air supply device, a heat exchanger connected to the fan and to the intake channel of the installation, a discharge device connected to the discharge channel of the installation and to the manifold and comprising a discharge channel, and a recirculation device comprising a recirculation channel connected to the air supply device and to the discharge device.

Abstract: An etching processing apparatus 1 has a transfer chamber 2, a plurality of processing chambers 3 and 4, and a plurality of cassette chambers 7 and 8. Inside the transfer chamber 2, a transfer mechanism 14 is provided. A control device 17 pauses the operation of the vacuum pump 16 after closing an opening/closing valve 15 of a vacuum evacuating mechanism, which vacuum evacuates the transfer chamber 2 in which the transfer mechanism 14 is provided, when the operation of the transfer mechanism 14 is paused for a predetermined time or longer. Accordingly, conservation of energy becomes possible without causing decrease of productivity.

Abstract: A vehicle air supply system having a compressor, an air dryer, a reservoir adapted to receive air from the compressor via the air dryer, and control means operable to cause a standard regeneration of the air dryer when a predetermined system condition is met, the control means being further operable to cause an intermediate regeneration of the air dryer in advance of said predetermined system condition being met.

Abstract: Control of temperature of the shelves in a freeze dryer compartment is achieved by circulating a cooled heat transfer fluid from a heat exchanger through a vacuum condenser independently of circulating the cooled heat transfer fluid either directly through the passageway chambers in the freeze dryer shelves, for cooling the shelves, or through a heater for heating the shelves. These circulations are effected by the selective control of electrically operated valves in fluid conduits automatically by a programmed computer.

Abstract: In a method for preventing the occurrence of an explosive state in a gas mixture, especially of solvents in air, in an essentially confined space, virtually complete oxidation of at least part of the gas mixture taking place, either the temperature difference .DELTA.T between the temperatures of the gas mixture before and after the oxidation is determined, and if the temperature difference .DELTA.T is greater than a maximal permissible temperature increase .DELTA.T.sub.max, safety measures are taken, or the temperature T.sub.1 of the gas mixture before the oxidation and the temperature T.sub.2 of the gas mixture after the oxidation are measured, and the measured temperatures T.sub.1 and T.sub.2 are compared with a minimum temperature T.sub.min before oxidation of the gas mixture and a maximum temperature T.sub.max after oxidation of the gas mixture, the difference between T.sub.max and T.sub.min being less than, or equal to, the maximal permissible temperature increase .DELTA.T.sub.
