Abstract: An increased air pressure forced hot air towel warmer comprising a substantially airtight enclosure configured to be more desirable and user friendly when placed in close proximity to a tub or shower whether mounted within cabinetry, on the wall or when permanently installed between existing standard 16 inch on center wall support studs while protruding as little as possible into the room. Intended for use with large area plush towels and bath sheets for which insertion in a limited width wall enclosure or shallow depth cabinetry leads to greater vertical depth of towel material to be penetrated and substantially increases the resistance to air flow, therefore back pressure, thereby necessitating increased supply pressure to maintain adequate hot air flow through the towel. Increased supply pressure is created without objectionable noise by use of low noise rotary blowers and associated pressure accumulator cavities arranged in tandem such that their respective pressure gradients are additive.

Abstract: A blast furnace head (11) including a material loading device comprising rotary chute (14) driven in rotation about a first, vertical axis of rotation (16), and a loading chute (15) at the outlet of same, driven in rotation about a second, vertical axis of rotation (17) laterally offset relative to the first axis of rotation (16). The gears (20, 21) assigned to both of the chutes (14, 15) are arranged within a sealing chamber (22). Within this sealing chamber (22), a means (28) is arranged for supplying integrated measuring devices (29 or 30), lubrication points or similar maintenance recipients, with these supply means (28) being drivable by one of the gears (20, 21) assigned to the two chutes, in particular by the gear (20) assigned to the rotary chute (14).

Abstract: Process tubes of a fired process heaters are provided with a more equal heat flux distribution about an exterior circumferential surface region thereof. More specifically, according to the present invention, there is provided on at least one circumferential segment of the exterior circumferential surface region of the process tube, a coating of a material having a selected thermal emissivity and/or thermal conductivity which is different from the thermal emissivity and/or thermal conductivity of another circumferential segment of the exterior circumferential surface of the process tube. In such a manner, a more equal heat flux distribution about an entirety of the exterior circumferential surface region of the process tube is established as compared to the heat flux distribution thereabout in the absence of the coating.

Abstract: A towel warmer comprising a cabinet enclosing a chamber with an opening, a door attached to the cabinet to close the opening, one or more coils heated by conducting hot water, the coils being positioned within the chamber opposite the opening, a resilient compressible support positioned on the door to compress cloth-like objects against the heated coils as the door is closed, and a latch to hold the door closed with force to maintain compression of the cloth-like objects against the heated coils.

Abstract: A pipe stand instrument heater system for heating an instrument within an enclosure supported by a pipe stand. The heater system includes a housing mounted to the pipe stand and a heater unit in the housing. A bracket is provided for mounting the instrument to the housing. The heater unit can be powered by electric, steam or other fluids.

Abstract: The invention relates to a method and a plant for manufacturing mineralized portland cement clinker. The method and plant provides for preheating, calcining, burning and finally cooling the clinker. The mineralizer may e.g. be gypsum, fluorine, or a waste product containing these or other mineralizers. The mineralizer is added to the feedstock after the feedstock has been fed to the process, preferably after the cyclone which handles the feed to the calciner, i.e. the last cyclone in the preheater, or the lowermost preheater stage in a plant which does not incorporate a calciner.

Abstract: A method is presented for uniformly heating plastically deformable material, which comprises particles of electrically conducting matter. This method comprises inducing an electric current, or causing hysteresis loss within such material, by using electromagnetic radiation with frequency between about 50 Hertz and about 10 MegaHertz, to cause heating of the material.

Abstract: A vapor delivery system for the manufacture of an optical preform includes a deposition bubbler (60) and another bubbler (40) referred to as a supply bubbler which is interposed between a reservoir (24) of a liquid and the deposition bubbler. Heat energy is applied to the supply bubbler and to the deposition bubbler to vaporize liquid therein. A carrier gas is introduced into the liquid in the supply bubbler at a location below the free surface and into the deposition bubbler to cause vapor of the liquid to become entrained in the carrier gas and to flow from the supply bubbler into the deposition bubbler and from the deposition bubbler to a substrate tube from which an optical preform is made. Facilities are provided for maintaining sufficient liquid in the supply bubbler and suitable temperatures of the liquid in the supply and deposition bubblers to control the vapor flow into and out of the deposition bubbler to prevent unintended perturbations in the deposition bubbler.

Abstract: Chunks of animal matter with 60% moisture content are fed into a cooker (1) via an inlet (3). Steam at 150.degree. C. is fed into a double skin via an inlet (6) and condenses to leave as water via an outlet (7). The application of heat to the animal matter causes greasy steam to be given off therefrom which leaves the cooker via an outlet (10). The remaining animal solids leave the cooker via an outlet (4) where they have a moisture content of 10%. The greasy steam is condensed in a condenser (19) and greasy steam condensate is discarded via an overflow (36). In the present installation, the major portion of the heat released by condensing the greasy steam is recovered and recycled, thereby reducing the energy requirements of the installation as a whole.

Abstract: Infra-red irradiation is combined with additional heating and/or drying to more effectively treat substrates. Irradiation from gas-fired infra-red radiators provides hot gaseous combustion products that can be directed to help heat and/or dry substrates. Width of irradiator can be made adjustable, as can its color temperature. Color temperatures as low as 950.degree. F. can be obtained without combustion catalysts such as platinum, by having a fine-mesh wire screen in front of ceramic fiber matrix burner face.

Abstract: Objects are levitated in a sound system substantially free of reverberation and reflection by positioning a small reflector in the path of sound waves. Interference between the primary waves and reflected waves creates a localized zone of minimized energy closely adjacent to the reflector in which an object may be stably levitated. The energy well thus produced is not dependent upon distance from the sound source, and the levitated object may be moved in any direction by moving the reflector. A plurality of reflectors may be employed to manipulate and combine levitated materials, and improvements in the processing of levitated objects are also achieved.
