Patent number: 10362798Abstract: A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.Type: GrantFiled: April 10, 2018Date of Patent: July 30, 2019Assignee: Bellwether Coffee Co.Inventors: Ricardo Lopez, John Sandhu, Arno Holschuh, Victor Escobedo, Benjamin Jones, Brandon McLaughlin, Neil Vesco, Henry D'Souza, David Kortbawi

Patent number: 10259052Abstract: A system for duplicating a master key includes a clamping mechanism for receiving and positioning a master key. The master key defines a major key axis and an intermediate key axis along which a key blade variably extends. The key blade has an upper surface and a minor key axis along a key thickness. A mechanical measurement device includes a probe that deflects along the intermediate key axis during a measurement process. A movement mechanism imparts relative motion along the major key axis between the mechanical measurement device and the master key. The mechanical probe follows the upper surface of the key blade. The mechanical measurement device generates a signal indicative of the deflection of the probe. A processor receives the signal and generates information usable for defining the machining of a duplicate key.Type: GrantFiled: August 2, 2018Date of Patent: April 16, 2019Assignee: The Hillman Group, Inc.Inventors: Richard L Gardner, Jr., Bradford Shayne Cooley, David Kortbawi

Patent number: 10252392Abstract: A system for duplicating a master key includes a mechanism for receiving and positioning a master key. The master key defines a major key axis and an intermediate key axis along which a key blade variably extends, and a minor key axis along a key thickness. Optical path components direct a light beam along the minor key axis. The light beam impinges upon the key blade. A portion of the light beam traverses the key blade. A detector receives the portion of the light beam that traverses the key blade. An apparatus imparts relative motion along the major key axis between the light beam and the master key. The light beam scans along the major key axis of the master key. A processor receives a signal from the detector as the beam scans along the major key axis and generates information usable for defining the machining of a duplicate key.Type: GrantFiled: May 4, 2018Date of Patent: April 9, 2019Assignee: The Hillman Group, Inc.Inventors: Richard L Gardner, Bradford Shayne Cooley, David Kortbawi
