Patent number: 10836236Abstract: A vehicle has a climate control system using a heat pump having a condenser heat exchanger that exchanges heat between refrigerant and working fluid within a hot fluid chamber, and an evaporator heat exchanger that exchanges heat between refrigerant and working fluid within a cold fluid chamber. A super-heated fluid pressure vessel may be in fluid communication with the cold fluid chamber by way of a heat exchanger and an electrically controlled variable delivery valve, and has an electric heater that may be powered by a drivetrain battery or by a shore power source. The hot fluid chamber provides heat to at least one cabin heat exchanger and to at least one ambient air heat exchanger. The cold fluid chamber is connected to at least one vehicle interior cooling module, to a waste heat source, and to a cold fluid chamber to outside heat exchanger.Type: GrantFiled: November 28, 2018Date of Patent: November 17, 2020Assignee: International Truck Intellectual Property Company LLCInventors: Gerald L.

Patent number: 10259908Abstract: A novel synthetic route to new classes of polymeric coupling agents using substituted epoxy monomers is reported. In the presence of an initiating agent and tris(pentafluorophenyl)borane catalyst, substituted epoxy monomers bearing polyalkylene oxide and trialkoxysilane moieties undergo a ring-opening polymerization. The polymerization is highly versatile and allows for the fine-tuning of functional, structural, and architectural features of the resulting polymeric coupling agents. These new polyalkylene oxides substituted with organosilyl groups are capable of bonding to and modifying inorganic surfaces. The products of this invention form thin hydrophilic films.Type: GrantFiled: October 5, 2016Date of Patent: April 16, 2019Assignee: Gelest Technologies, Inc.Inventors: Barry C. Arkles, Gerald L. Larson, Jonathan D. Goff, Ferdinand Gonzaga

Patent number: 9995209Abstract: A rotary engine has a circular shaped rotor and stator. The rotor has an expansion chamber for combustion and the stator has thrust director gate that passes through a passageway through the stator face to alternatively ride along the face of the rotor or to ride within the expansion chamber of the rotor. Passageways through the stator and radially close to the thrust director gate allow for air, fuel, and an ignition source to pass through the stator allow for ignition and expansion of the fuel within the expansion chamber. The thrust director allows for thrust to be applied to the rotor to rotate the rotor. An exhaust manifold, also passing through stator, and also radially aligned with the expansion chamber allows exhaust gases from combustion to be released from the expansion chamber as the rotor rotates the expansion chamber adjacent to the exhaust manifold.Type: GrantFiled: March 18, 2015Date of Patent: June 12, 2018Assignee: International Engine Intellectual Property Company, LLCInventor: Gerald L.
