Publication number: 20210394997Abstract: An apparatus is provided that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical shape having an open end, a closed end, and a longitudinally extending bore or opening extending from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received by a rotational device. The mixing apparatus can be used to mix various sized containers containing contents having one or more materials to be mixed.Type: ApplicationFiled: September 3, 2021Publication date: December 23, 2021Inventors: Donald Dunn, Chance E.

Patent number: 9483924Abstract: A smoke detector system that includes an airflow barrier installed between a detector base unit and a mounting surface to ensure there is separation between the detector base unit and the mounting surface. The barrier isolates and seals the smoke detector to prevent the formation of condensation in or around the smoke detector. The barrier further includes a cavity that can collect condensation if condensation does occur. The condensation is then directed to a channel that extends around the periphery of the airflow barrier. Additionally, the channel includes weep holes so that condensation has a means to exit the detector.Type: GrantFiled: May 26, 2015Date of Patent: November 1, 2016Assignee: Tyco Fire & Security GmbHInventors: Alexander Singer Andrews, Donald Dunn Brighenti

Patent number: 6438973Abstract: Electronic circuitry provides protection for refrigeration machines by continuously monitoring supply voltage conditions and various other conditions. Information regarding abnormalities detected in the refrigeration machines or supply voltage is stored in a memory. The stored information may then be downloaded from the memory by a service technician. The electronic circuitry is universal and can therefore be used with various refrigeration machines. Further, the efficiency of a low temperature storage cabinet is enhanced by cycling the evaporator motor in comparison to a compressor percentage run time. Other factors are also considered in the running of the reach-in cabinet evaporator fan.Type: GrantFiled: May 1, 2000Date of Patent: August 27, 2002Assignee: Hoshizaki America, Inc.Inventors: Kazuhiro Yoshida, Donald Dunn, Robert McDonald, William P.
