Publication number: 20040016741Abstract: The present invention relates to a portable adhesive dispensing appliance with adjustable duty cycle. Rather than applying power continuously to the heating element, the element power is intermittently switched over to a variable duty cycle. Savings are gained in three areas: extended life of the element; less heat lost to thermal radiation; and less adhesive waste due to dripping and overheating. The duty cycle may be adjusted manually or automatically based on the temperature of the heating element, or tip. Additionally, the voltage and/or current to the heating element may be adjusted, either manually or automatically, for more rapid recovery during high usage periods. Higher throughput is achieved by sensing the temperature, comparing the temperature to a desired temperature, and then increasing the duty cycle by either or both one of increasing the frequency of duty pulses and/or lengthening the duration of the duty pulses.Type: ApplicationFiled: May 20, 2003Publication date: January 29, 2004Inventor: Walter Evanyk

Patent number: 5635143Abstract: A method and apparatus for the microwave removal of contaminated concrete surfaces. The apparatus comprises a housing adapted to pass over a support surface. The housing includes a waveguide for directing microwave energy to the surface at an angle maximizing absorption of microwave energy by the surface. The apparatus is further provided with a source of microwave energy operably associated with the waveguide, wherein the microwave energy has a frequency of between about 10.6 GHz and about 24 GHz and acts to remove the uppermost layer from the surface. The apparatus further includes a debris containment assembly comprising a vacuum assembly operably associated with the housing. The vacuum assembly is adapted to remove debris from the area adjacent the surface.Type: GrantFiled: September 30, 1994Date of Patent: June 3, 1997Assignee: Martin Marietta Energy Systems, Inc.Inventors: Terry L. White, Timothy S. Bigelow, Charles R. Schaich, Don Foster, Jr.

Patent number: 5634388Abstract: Marks such as patterns, designs, numbers, or the like are cut out of a mark sheet or mark sheets placed on a glass base by a thermal cutter having a heated cutting bit. The thermal cutter is movable two-dimensionally over the mark sheet, and is also vertically movable between an upper position in which the thermal cutter is lifted off the mark sheet supported on the base and a lower position in which the thermal cutter is lowered in contact with the mark sheet supported on the base. The thermal cutter is angularly movably supported on an eccentric shaft that is rotatable by a stepping motor. The thermal cutter has a cutting bit resiliently urged by a spring for stable positioning. A range or ranges in which desired marks are to be cut out of a mark sheet or mark sheets can be confirmed by being traced by the thermal cutter before the marks are actually cut out. When mark numerals indicative of desired numbers are to be cut out, such mark numerals are rearranged and displayed for the operator's information.Type: GrantFiled: June 7, 1995Date of Patent: June 3, 1997Assignee: Kabushiki Kaisha Tokyo HoraishaInventors: Shinichi Fuchigami, Shingi Suzuki, Takeshi Kongo, Tetsuo Nakada, Takehiro Kodama, Sachie Sato

Patent number: 5452633Abstract: A process for the thermal cutting of a running, meltable fabric run includes cutting the fabric run by a hot cutting wire. The cutting wire extends in a plane extending essentially perpendicularly to the travel direction of the fabric run. The cutting wire is inclined relative to the fabric run by an angle of greater than 0.degree. and smaller than 90.degree..Type: GrantFiled: January 28, 1994Date of Patent: September 26, 1995Inventor: Francisco Speich

Patent number: 5446819Abstract: An optical fibre cable terminating tool (16) and method for terminating a cable to a connector (13) of the type having at one end a ferrule (14) provided with a meltable adhesive therein. The tool (16) has a recess 16a for receiving and locating a connector (13) with its ferrule end projecting from the recess and permitting the end to be inserted into a heating recess of an oven. A heat sensitive element (36) is provided on the tool spaced from the recess end and this displays a change in appearance at a predetermined temperature which is indicative of a higher temperature at the ferrule at which higher temperature the adhesive is molten.Type: GrantFiled: July 14, 1994Date of Patent: August 29, 1995Assignee: ITT Industries, Inc.Inventors: Nigel S. Foster, David P. Murray
