Abstract: A heating furnace (561) comprises an inner cylindrical part (601) adapted to rotate about a predetermined axis (C1), a cover part (581) containing the inner cylindrical part therewithin and being capable of confining heat therewithin, and a heat supply part (92) for supplying the heat into the inner cylindrical part. The inner cylindrical part includes a first end part (65A1) located on one end side of the predetermined axis, a second end part (65B1) located on the other end side of the predetermined axis, and a plurality of connecting members (661) for connecting the first and second end parts to each other and circulating an object within the inner cylindrical part as the inner cylindrical part rotates.

Abstract: A mixing laundry dryer vane has a general profile which is scooped or “saddle” shaped. The mixing dryer vane has two relatively tall end portions and a reduced height central portion. The mixing dryer vane may have an upper surface that extends arcuately from one taller end portion to the other taller end portion. The arcuate shape may define along the length of the vane a relatively deep concavity which defines the reduced height central portion. The mixing dryer vane's taller end portions may be configured and positioned to cause “wiping” of clothes off and away from an exhaust duct grill within the dryer. The taller end portions of the vane may have a generally propeller-like twist that directs clothes towards the scooped central portion of the vane. The scooped mixing vane in combination with other non-scooped dryer vanes can reduce or eliminate the tendency of harmonic tumbling of a load.

Abstract: A cleaning apparatus having a sealable pressure vessel and an agitator for agitating an article, such as clothing, in a liquid within the vessel to remove contaminants from the article. A fluid system supplies fresh liquid to the vessel and drains used liquid from the vessel to separate excess contaminated from the article, a portion of the contaminated liquid being retained by the article after this separation. One or more heating elements are activatable to vaporize the retained liquid, and a vacuum system is activatable to reduce the pressure in the sealed vessel while the heating elements are activated, such that the boiling point of the retained liquid is substantially reduced from that at atmospheric pressure. The liquid may be plain, ozonated or carbonated water, or a mixture thereof, and may be cooled by a heat exchanger before being introduced into the sealed vessel. Agitation during washing and drying is minimized for use of the apparatus as an alternative to dry cleaning.
