Patent number: 6780077Abstract: A toy vehicle combination includes a master toy vehicle and a slave toy vehicle. The master toy vehicle includes a transmitter configured to broadcast an IR tracking signal. The slave toy vehicle includes at least first and second directional IR receivers configured to receive the tracking signal from different directions around the slave toy vehicle and is configured to follow or evade the master toy vehicle, which is conventionally remotely controlled.Type: GrantFiled: October 29, 2002Date of Patent: August 24, 2004Assignee: Mattel, Inc.Inventors: Chris T. Baumgartner, Joseph T. Moll, Truman J. Gilbert, Stephen N. Weiss, Nathan Bloch, David V. Helmlinger, Gregory Nungester

Patent number: 6698438Abstract: A fine filter assembly for a dishwasher includes a filter body having a soil accumulation trough. The soil accumulation trough defines a substantially helical flow path between a fine filter inlet and an outlet. A natural flow path is therefore provided to efficiently clean fine the filter assembly with downwardly directed fluid jets generated by a lower spray arm assembly. Soil is directed to a fine filter drain tube with relative ease, thereby facilitating use of more efficient use of a drain pump inlet as a soil collection chamber during wash cycles.Type: GrantFiled: December 22, 2000Date of Patent: March 2, 2004Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, David V. Helmlinger

Patent number: 6692333Abstract: A toy vehicle has front and rear chassis portions and a flipping mechanism which allows the front chassis portion to rotate 360 degrees with respect to the rear chassis portion about a longitudinal axis. The flipping mechanism includes a triggering mechanism, a rotational drive mechanism and a mechanism to prevent damage to a main spring which drives the rotational motion of the front chassis relative to the rear chassis. The toy vehicle may be remote controlled, and include a remote control transmitter. One remote control transmitter includes a left hand and a right hand portion, with the two portions being pivotable with respect to one another to activatea control switch.Type: GrantFiled: February 28, 2003Date of Patent: February 17, 2004Assignee: The Obb, LLCInventors: Androc L. Kislevitz, Adam L. Kislevitz, Noah L. Kislevitz, Justin M. Discoe, David V. Helmlinger, David J. Ribbe

Patent number: 6641058Abstract: A dishwasher spray arm hub assembly includes a hub having a first central bore extending therethrough and a conduit feed extending therefrom. The conduit feed is in flow communication with the central bore and a venturi insert is disposed in the hub central bore. The venturi insert also includes a second central bore extending therethrough. The first bore and the second bore together form a fluid bypass channel in flow communication with the conduit feed. Therefore, a lower spray arm assembly and a spray arm conduit for upper spray arm assemblies may be simultaneously fed through the hub assembly.Type: GrantFiled: December 28, 2000Date of Patent: November 4, 2003Assignee: General Electric CompanyInventors: Arjan Johannes Hegeman, David V.

Publication number: 20030114075Abstract: A toy vehicle remote control transmitter unit wirelessly controls the movements of a programmable toy vehicle. The toy vehicle includes a motive chassis having a plurality of steering positions. A microprocessor in the transmitter unit emulates manual transmission operation of the toy vehicle by being in any one of a plurality of different gear states selected by an operation of manual input elements on the transmitter unit. Forward propulsion control signals representing different toy vehicle speed ratios associated with each of the gear states are transmitted from the transmitter unit to the toy vehicle. The motive chassis has a steering feedback sensor with a plurality of defined steering positions to vary rate of steering position change to avoid overshoot.Type: ApplicationFiled: October 30, 2002Publication date: June 19, 2003Inventors: Joseph T. Moll, James M. Dickinson, Frank W. Winkler, David V. Helmlinger, Charles S. McCall, Stephen N. Weiss

Patent number: 5730767Abstract: A filter or dust collector which includes a housing for supporting a filter media formed as an endless belt to move along said housing as dirty air passes inwardly through the moving filter media. The surfaces of the housing which support the moving filter media are formed with suction channels, and the filter media is provided with a sealing strip that includes a slack portion of flaccid material that can be drawn partially into the suction channel by the suction therein to enhance the seal along the side edges of the moving filter media.Type: GrantFiled: July 30, 1996Date of Patent: March 24, 1998Assignee: Pneumafil CorporationInventor: David V.
