Abstract: Heat can be supplied effectively to a porous member of a vaporizer apparatus so that a vaporizing operation can be carried out smoothly and efficiently. The vaporizer apparatus includes a vaporizer section having a porous member including a liquid receiving surface and a vapor discharge surface. A feed supply section supplies a liquid feed material to the liquid receiving surface of the porous member. A heating medium passage is in thermal contact with the porous member. A heating medium supply system flows a heating medium of a temperature higher than a vaporization temperature of the liquid feed material through the heating medium passage.

Abstract: A line for the semiautomatic feeding of industrial hides, particularly for setting-out/drying machines and vacuum driers, includes a loading/unloading device (5, 5') that lies between the unloading section of the setting-out/drying machine (2) and the drying tables (3') of the vacuum drier (3); the device (5, 5') can be actuated on command after spreading the hides (P, P') on each table of the vacuum drier. The loading/unloading device (5, 5') has at least one movable surface (8, 8') and has a translatory direction (V) that lies substantially at right angles to the main dimension of the tables (8) of the vacuum drier (3).

Outer wall (105) has a fluent material inlet opening (119) such that with the fluent material inlet opening (119) in register with the flow path fluent material outlet (27), the fluent material will flow by gravity through the fluent material inlet opening (119) in the outer wall into the chamber (126). The inner wall (107) has a fluent material outlet opening (127) therein such that the fluent material in the chamber (126) will flow by gravity from the chamber to a fluent material discharge outlet (15).

Abstract: A cordless, hydrocarbon fuel powered hairdryer. The invention incorporates a novel electronic control system which evaluates the thermal and electrical conditions within the hairdryer during its operation. Two fuel flow valves are provided. The first fuel flow valve is mechanically actuated and opens and closes the valve in the hydrocarbon fuel cartridge. The second fuel flow valve is a solenoid valve that cannot open without a predetermined voltage being supplied. Application of the predetermined voltage will allow gas to flow through this second valve and into the area where the fuel is ignited. Only when both valves (the mechanical and the solenoid) are open, can fuel flow. A microcontroller monitors the temperature conditions in the combustion area, and controls system conditions such as power to the solenoid valve and to the fan motor to prevent uncombusted gas from building up and presenting a safety hazard.

Abstract: A double backer for curing the web bonding adhesive and drying the corrugated paperboard web utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel. Supplemental holddown force may be provided by banks of spring fingers supported above and in contact with the holddown strips on a transverse support rod which may be rotated to vary the amount of supplemental holddown force. Alternately, the holddown strips may comprise continuous cables in which one run of the cables rests upon the moving web to provide the web holddown and a second run includes high friction cable portions which are movable into driving contact with the upper surface of the web to pull it through the heating section, as for initial web thread up.

Abstract: The inventive clothes dryer is provided with a system for preventing the overheating of the clothes in the drum caused by the abnormality in the V-belt, such as the break or derailment thereof. By the system, the power supply to the motor is halted temporarily while the motor is rotated at a predetermined speed, whereafter the motor keeps rotating due to its inertia. During the inertial rotation of a predetermined period of time, the number of rotations of the motor is counted. When the V-belt is in the normal state, the motor is loaded appropriately, so that the speed of the motor falls rapidly during the inertial rotation, and the number of rotations is accordingly small. When, on the other hand, the V-belt is in an abnormal state, the number of rotations is large. Therefore, the state of the V-belt is checked by comparing the number of rotations to a predetermined value, and when the number is smaller than the predetermined value, the drying operation is stopped.

The endless belts are smoothly driven by rotation of the driving rollers due to the protrusion-aperture engagement.

Abstract: A method and apparatus for impingement drying and/or through-drying of a paper or material web in which the web is dried by blowing hot air and/or superheated steam and/or equivalent from an impingement drying device in a direction substantially perpendicular to the web, and the web is passed on support of a wire or equivalent past the impingement drying device. In the area of the impingement drying device, the web and wire are supported from the opposite side of the wire, opposite in relation to the web, by blowings produced from vacuum blow box substantially across the entire width of the web. One set of blowings from the blow box are blown at a speed substantially higher than the speed of the drying wire. The outlet direction of the blowings is substantially the same as the running direction of the drying wire in this area, and as such, steam and/or air is/are ejected out of the space between the drying wire and the wall placed in connection with the blow boxes that produce the blowings.

Abstract: The present invention is directed to drying and heating processes and to an apparatus incorporating a pulse combustion device that can be used in a drying system or in a heating system. In general, the apparatus includes a pulse combustion device for the combustion of a fuel to produce a pulsating flow of combustion products and an acoustic pressure wave. The pulse combustion device has a combustion chamber connected to at least one resonance tube. A resonance chamber surrounds at least a portion of the pulse combustion device and includes a nozzle downstream from the resonance tube. The nozzle accelerates the combustion products flowing therethrough and creates a pulsating velocity head. In a drying system, the nozzle exits into a drying chamber where the combustion products contact a feed stream.

Abstract: A bed plate for a fluid bed apparatus comprises a great plurality of bulges or dents each having at least one through-going gas flow opening defined therein. Conventional bed plates having openings of the gill type inevitably comprises small cracks or notches formed in the edge portion defining each of the gas flow openings. According to the invention the gas flow openings are formed in the bulges or dents in a manner so as to exclude the formation of such notches in the edge portion. This may, for example, be done by forming such openings with crack free edges prior to or after the formation of the bulges or dents. Thus, the openings may be formed by punching, drilling, laser cutting or the like. Each of the gas flow openings is directed in relation to the plane of the bed plate so as to cause a flow of gas, which is passed through the opening, to contact an adjacent part of the bed plate, which interconnects the bulges or dents.
