Patent number: 5796075Abstract: At least one radiant heating resistor (10) formed from a corrugated flat material band has in different orientations projections (28) projecting from a corrugated longitudinal edge (14), which on the one hand for retaining purposes engage in an insulation (3) and on the other hand form longitudinal portions (39) with a slightly lower electrical resistance and which for the conventional operating power appear dark compared with the intermediate, visibly glowing longitudinal portions (38). Thus, on putting into operation, there is a very rapidly starting, punctiform lighting up of the corresponding longitudinal portions (38), which then spreads out to a wavy line, as well as a very reliable anchoring of the heating resistor (10).Type: GrantFiled: February 23, 1996Date of Patent: August 18, 1998Assignee: E.G.O.

Patent number: 5796914Abstract: An electrically activatable fumigating device and the method of its use. The device is adapted to be useable with vertically or horizontally oriented, wall-mounted electrical receptacles as well as receptacles mounted in horizontal countertops, all without the need for moving parts in the device. This is accomplished by the relative angle of the electrical plug to the longitudinal axis of a well contained within the body of the fumigating device from the mouth of which active ingredient is expelled by chemical reaction. Use of a modular heating assembly aids in allowing economical manufacture so that the fumigating device may be made inexpensively enough to be a single use device, with a self-disabling, single use, electrically activated heating means.Type: GrantFiled: April 17, 1996Date of Patent: August 18, 1998Assignee: S. C. Johnson & Son, Inc.Inventors: John J. Gatzemeyer, Robert E. Corba, Scott W. Demarest, Nicholas M. Gerrits

-
Patent number: 5781691Abstract: What is disclosed is a hand-held steam dispensing apparatus having a removable water reservoir, the reservoir containing a diaphragm dividing the reservoir into a large chamber and a small chamber wherein water from the large chamber may flow quickly into the small chamber, but water in the small chamber is restricted from flowing into the large chamber, a spring biased bellows pump with two one-way valves for allowing water to be pumped out of the bellows into a heating enclosure when the bellows is compressed and for allowing water to fill the bellows when the bellows expands. The heating chamber is coated to cause the water to form a thin film whereupon the water is heated to form hot water vapor which then expands through a barrel into a perforated tube. The water vapor passes out of the perforations to provide hot water vapor to a user's hair.Type: GrantFiled: June 24, 1996Date of Patent: July 14, 1998Inventor: Daniel S. C. Kwok
