Publication number: 20240109564Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Padam Dhoj Swar, Carl L.

Patent number: 5664882Abstract: A system for concurrently remediating contaminated soil and producing hot mix asphalt includes a single inclined rotary drum; a burner assembly with a burner head spaced intermediately within the drum and oriented to direct a flame and hot gas stream upstream therefrom; a secondary air tube for providing atmospheric air to the burner head for supporting combustion; a drying zone with veiling flights upstream from the burner head for receiving, drying and heating virgin aggregate; a combustion zone with combustion flights downstream from the drying zone and upstream from the burner head for receiving and remediating contaminated soil by heat transfer from the virgin aggregate, the flame and the hot gas stream and for oxidizing volatile contaminants vaporized from the contaminated soil; an isolated mixing zone for receiving various materials including the virgin aggregate, the remediated soil, recycle asphalt, and certain constituents for producing hot mix asphalt therein from thermal energy contained within thType: GrantFiled: April 4, 1996Date of Patent: September 9, 1997Assignee: Cedarapids, Inc.Inventors: Andrew W. Green, Joseph E. Musil

Patent number: 5528113Abstract: A loosely coupled inductive power transfer system suitable for transferring power to a mobile conveyer platform or a vehicle has pick-up coils wound on flux concentrator(s). One or more large flat horizontal ferrite cores 607, 608 are used to concentrate the horizontal component of magnetic flux from an extended volume into one or more secondary or pick-up coils 613. Each shock-resistant core comprises an array of many individual strips of ferrite held in close contact. One, more usually two, or perhaps more resonant pick-up windings are wound about each core and each winding has a shorting switch (within 602, 603 . . . ) placed across it. A controller 601 connects a controlled output voltage on to an output bus 605, 606 from the best-placed pick-up winding on any one core at any moment, while holding the others in a shorted hence inactive state.Type: GrantFiled: October 21, 1994Date of Patent: June 18, 1996Inventors: John T. Boys, Andrew W. Green

Patent number: 5484226Abstract: The invention is directed to automated controls of an asphalt paver wherein the speed of the conveyor is automatically controlled at a rate proportional and responsive to the speed of the auger and the conveyer is free from having a material sensor and speed control responsive thereto.Type: GrantFiled: January 18, 1994Date of Patent: January 16, 1996Assignee: Caterpillar Paving Products Inc.Inventors: David Emerson, Andrew W. Green

Patent number: 5450305Abstract: This resonant power supply produces a varying magnetic field from a resonant inductor. Two active switches drive, but remain outside, a resonant circuit, also including resonant capacitor. A phase-splitting transformer provides, via a decoupling inductor, one connection for a power supply; the return is through the active switches, which are either off or are from time to time driven alternately by the controller so as to maintain the resonant current in the resonant circuit. Applications include induction heating and induction hobs for cooking, and also a power source for inductively powered vehicles (or other inductively powered devices) adjacent to an inductive pathway.Type: GrantFiled: August 5, 1992Date of Patent: September 12, 1995Assignee: Auckland Uniservices LimitedInventors: John T. Boys, Andrew W. Green

Patent number: 5293308Abstract: A contactless inductive power distribution system operating at 10 KHz has a self tuning resonant power supply connected to a resonant primary conductive path comprising a pair of parallel litz wire conductors each encapsulated within an insulated sheath and supported on a structural monorail beam on which a plurality of electric vehicles can run. Each vehicle has an electric motor capable of deriving power from a resonant pick-up coil wound on a ferrite core mounted on the vehicle in close proximity to the primary conductors. Each vehicle also has switching means capable of preventing a lightly loaded vehicle from presenting a reduced load to the resonant primary. In one version this comprises an isolating coil having a switch to switch the coil between an open circuit and a short circuit, so that when the switch is switched from one state to another state the power coupled between the primary conductive path and the pick-up coil is changed.Type: GrantFiled: January 30, 1992Date of Patent: March 8, 1994Assignee: Auckland Uniservices LimitedInventors: John T. Boys, Andrew W. Green

Patent number: 5203642Abstract: An extendable, floating screed for an asphalt paver including screed extensions which extend, retract and pivot relative to the main screed. The screed extensions are mounted to the main screed with a zero clearance pivot joint. The disclosed pivot joint permits the screed extension to extend, retract and pivot relative to the main screed which maintaining zero clearance at the pivot. The pivot joint includes respective mounting plates on the extension screed and the main screed which are adapted for substantial coextensive engagement with each other in a plane perpendicular to the longitudinal axis of the paver. A threaded fastener is received in coaxial apertures in the mounting plates for defining the pivot axis of the extension screed thereby permitting slope adjustment of the extension screed relative to the main screed. Tightening of the fastener draws the mounting plates in tight engagement with each other thereby establishing the zero clearance pivot joint.Type: GrantFiled: April 3, 1991Date of Patent: April 20, 1993Assignee: Barber-Greene CompanyInventors: John W. Heller, Andrew W. Green, James H. Bassett

Patent number: 5201603Abstract: A tow point for an asphalt paver, which allows the operator to: (1) select either a fixed or sliding tow point connection; and (2) select from among several possible locations of each, thereby adjusting the distance between the screed and transverse auger of the paver. Combination of these features in a single machine makes it possible to lay down an asphalt mat of uniformly desired thickness, while optimizing use of the aggregate batch particles.Type: GrantFiled: May 17, 1991Date of Patent: April 13, 1993Assignee: Caterpillar Paving Products Inc.Inventors: James H. Bassett, Jay A. King, Andrew W. Green, David Emerson
