Patent number: 6036793Abstract: The present invention provides a method of heat-treating an oxygen-sensitive workpiece to minimize any oxidation of the workpiece, as well as an improved door seal specially suited for use with oxygen-sensitive products. In the method, an oven has an oven chamber and an outer housing, with an enclosure being defined therebetween. The workpiece is placed in the oven chamber and the chamber is sealed. Heated inert gas is circulated within the enclosure to heat the oven chamber and to hold it at a desired treatment temperature. The oven chamber is then cooled to a threshold temperature of the workpiece using inert gas. The chamber is then cooled further by circulating aerobic gas, preferably ambient air, within the enclosure. Another embodiment of the invention provides an oven with a housing forming an oven chamber, the oven chamber having a door opening in one of said walls.Type: GrantFiled: October 14, 1997Date of Patent: March 14, 2000Assignee: Despatch Industries Limited PartnershipInventors: Hans L. Melgaard, Louis A. Larson

Patent number: 5788484Abstract: The invention provides an oven which can be used to rapidly heat and cool a workpiece. In one embodiment, the oven includes a first duct which defines an initial leg of an enclosed air flow path and which has an inner panel and a heat exchanger. This first duct has an inlet end and an outlet end, the inlet end of which is connected to a temperature-controlled air supply. The oven also includes a second duct which defines a final leg of the enclosed air flow path and which has an inner panel spaced from the first duct's inner panel to define an oven cavity. The oven also has a connecting conduit connecting the outlet end of the first duct to the second duct and which defines an intermediate leg of the enclosed air flow path. In a preferred embodiment, the first duct is the lower of the two ducts and includes a plurality of holes through at least the inner panel of the duct.Type: GrantFiled: June 29, 1995Date of Patent: August 4, 1998Assignee: Despatch Industries Limited PartnershipInventors: Hans L. Melgaard, Louis A. Larson

Patent number: 5516489Abstract: An apparatus for testing peroxide concentration in a gaseous sterilant. A preferred embodiment of the apparatus includes a condenser for condensing the gaseous sterilant into a liquid condensate; an aliquot collector of predetermined volume to receive the condensate; a reaction chamber containing a catalyst for dissociating the peroxide; and a pressure monitor for detecting pressure changes in the reaction chamber as a function of time. The pressure monitor of this apparatus is capable of detecting a threshold pressure and an upper pressure and it includes a timer to measure time change between detection of the threshold pressure and the upper pressure.Type: GrantFiled: August 19, 1993Date of Patent: May 14, 1996Assignee: Despatch Industries, Inc.Inventors: Hans L. Melgaard, Louis A. Larson

Patent number: 5436569Abstract: The present invention, in one embodiment, provides a testing apparatus for electronic components to monitor their behavior at elevated temperatures. The invention comprises a transport belt with at least one carrier attached to the transport belt, the carrier being capable of retaining an electronic component. The carriers are adapted to contact bus bars positioned adjacent the transport belt to electrically connect a component retained by the carrier to an electrical power supply. The apparatus includes means for ramping up the electrical power applied to the component from an initial low voltage to a second, testing voltage.Type: GrantFiled: September 30, 1994Date of Patent: July 25, 1995Assignee: Despatch Industries, Inc.Inventors: Hans L. Melgaard, Louis A. Larson, Brian E. Hajder, Phillip G. Jordon, Eric W. Nelson

Patent number: 5431491Abstract: A method and apparatus for automatically inserting and ejecting electrical connectors of electronic component test trays from electrical connectors in a panel of an environmental test chamber, e.g. an oven, at the beginning and end of a test period to facilitate loading and unloading the test trays. The electronic components are inserted into test trays so that electrical connections are made with test tray conductors which terminate at a test tray connector. The trays are loaded into the oven in an insertion cycle by manually sliding them onto lateral tray supports with the tray connector ends aligned with mating electrical connectors in the panel of the test oven. The insertion cycle of a track guided, carriage mounted, inserter/ejector mechanism is commenced wherein the mechanism is advanced from tray to tray to sequentially insert the tray connectors into the panel mounted connectors until all trays are inserted. The oven door is closed and the test is conducted.Type: GrantFiled: October 12, 1993Date of Patent: July 11, 1995Assignee: Despatch IndustriesInventors: Hans L. Melgaard, Louis A. Larson, Wendell Schafer

Patent number: 4313669Abstract: An improved photographic print stacking tray device includes a print tray concavely bowed transversely to the direction of travel and a central deflector. As the individual photographic prints are discharged from a conveying line onto the print tray, the central deflector pushes the central portion of each print downwardly while the side edge portions of each print are deflected upward by the print tray so that each print is bowed, thereby giving each print greater beam strength in the direction of travel.Type: GrantFiled: October 27, 1980Date of Patent: February 2, 1982Assignee: Pako CorporationInventors: Louis A. Larson, Charles L. Euteneuer

Patent number: 4139980Abstract: An automatic film conveying and packaging mechanism for conveying cut film lengths forwardly from a film cutter to a packaging envelope while maintaining continuous contact with the film lengths between a pair of opposed upper and lower conveyor assemblies and driving the lengths directly into the packaging envelope in stacked relation to each other with the trailing ends thereof positively disposed in substantial alignment with each other and in rearwardly spaced relation to the discharge end of the upper conveyor assembly.Type: GrantFiled: April 11, 1977Date of Patent: February 20, 1979Assignee: PAKO CorporationInventors: Louis A. Larson, Robert E. Diesch

Patent number: 4114349Abstract: A photographic print sorting, conveying and packing mechanism includes a main conveyor line and a plurality of branch conveyor lines with an initial feeding device which receives individual cut prints from a print cutter and feeds the prints into the main conveyor line which defines a main flow path. All of the conveyor lines include a plurality of driver rollers spaced apart less than the length of each cut photograph so that one roller will always be in contact with the prints to maintain positive driving contact with the prints at all times during their successive travel along the conveyor lines. The conveyor lines also include deflecting elements ahead of each roller to flatten momentarily the curl in each print and insure proper driving engagement between the rollers and the print.Type: GrantFiled: April 11, 1977Date of Patent: September 19, 1978Assignee: Pako CorporationInventors: Gerald A. Jensen, Louis A. Larson, Robert E. Diesch
