Patent number: 5419306Abstract: An apparatus which uses friction to generate heat for heating liquids. The apparatus includes a cylindrical rotor disk housed inside a close-fitting housing structure. The rotor disk is connected to the shaft of a motor which turns the rotor disk at high revolutions inside the rotor chamber of the housing structure. The rotor disk has a plurality of curved, outward radiating, closed-end passageways formed therein. During operation, liquid flows into the housing structure via an inlet port which fills the rotor chamber of the housing structure and the curved passageways in the rotor disk. When the rotor disk is rotated at high speeds, the liquid located inside the curved passageways is pulled outward by centrifugal forces which creates a vacuum therein. When the vacuum becomes sufficient, the liquid "cracks" or boils at a low temperature. The resulting vapor formed inside the curved passageway suddenly forces the liquid remaining inside the curved passageway outward and exit at relatively high speed.Type: GrantFiled: October 5, 1994Date of Patent: May 30, 1995Inventor: Michael T. Huffman

Patent number: 5046480Abstract: An apparatus for the heating of air with a series of compression and expansion stages. The heating system includes four primary stages, centrifugal turbine compression, expansion through diffusing vanes, expansion into a low pressure chamber and nozzle compression. The thermal energy transferred to the air during these compression and expansion stages is of a degree to omit the need for a heat exchanger. The turbine compression stage heats and compresses the air significantly, while the following three stages convert this very high pressure and temperature air to a level that allows the air to be directly discharged into standard heating ducts. The diffusing vanes decrease the velocity of the air discharged from the compression turbine and the expansion chamber lowers the pressure to sub atmospheric pressure. The final stage compresses the air to standard atmospheric pressure and compensates for the heat lost in the expansion chamber.Type: GrantFiled: June 8, 1990Date of Patent: September 10, 1991Inventor: William E. Harris

Patent number: 4781151Abstract: This invention utilizes a combustionless heat source wherein a vaned rotor having efficiently designed vanes is rotatably supported within a cavity inside a cylindrically-shaped, cast aluminum block. The vaned rotor is rotated by connection to a power source and thereby imparts mechanical energy of motion to a heat transfer fluid encased within the cavity. Frictional forces developed by agitated molecules of the fluid convert the mechanical energy of motion into heat. The heat thus generated moves uniformly throughout the cylindrically-shaped block and heat transfer fluid is circulated through a circumferential passageway contiguous to substantially all of the outer cylindrical surface of the block and absorbs the heat generated inside the cavity. The heated fluid is then conducted to a remote heat transfer station. An electrical control circuit governs the sequencing of heat demand, heat production and heat transfer cycles.Type: GrantFiled: November 24, 1986Date of Patent: November 1, 1988Inventors: George H.

Patent number: 4596077Abstract: A heating process and its apparatus reduces air pressure within a chamber at a balanced level. The air retained within the chamber or the air suctioned through an outer air suction means is suctioned forcibly by rotation of rotary means disposed in the chamber and discharged outside the chamber through an inner air discharge means until air pressure within the chamber is reduced to a balanced level. Meanwhile, air friction heat is generated by continuous rotation of the rotary means, thereby the interior of the chamber is heated by air friction heat. Cooled outer air suctioned by the outer air suction means is heat-exchanged with heated air discharged by the inner air discharge means.Type: GrantFiled: June 20, 1983Date of Patent: June 24, 1986Inventor: Nobuyoshi Kuboyama

Patent number: 4554906Abstract: A friction boiler system has a rotary member frictionally engaging a housing having adjustable fit to the rotary member. The rotary member has a gray iron cover fixed on it and rotating with it. The housing is in two halves split longitudinally, each half has fixed therein a hemi-cylindrical liner of gray iron for fitting the circumference of the rotary member. To adjust the fit, a wedge on each side, driven by a screw-actuated cam, sets the spacing between the housing halves, against spring bias urging the housing halves together. The screw actuated cam has a straight portion guided by guideways and an angled portion inclined to the direction of wedge motion and riding in a recess in the respective wedge. A heat-transfer circulation system carries fluid heated by the frictional boiler system to point of use, and return, if a closed system is used. An electric motor may be employed as one form of power. Kinetic energy of other origins can be directly and efficiently converted to thermal energy by the system.Type: GrantFiled: October 12, 1984Date of Patent: November 26, 1985Inventors: William E.
