Abstract:

The present disclosure provides a thermal management device comprising a vapor chamber, a heat pipe in fluid communication with the vapor chamber, and a fin in thermal contact with the heat pipe. The vapor chamber may contain a first working fluid and may facilitate transfer of thermal energy from a source of thermal energy to the first working fluid. The fin may comprise a fluid flow path configured to direct a second working fluid from a first opening to a second opening. The first opening may be oriented along a first direction of flow towards the fin, and the second opening may be oriented along a second direction different than the first direction. The heat pipe may direct the first working fluid from the vapor chamber through the heat pipe and may facilitate transfer of thermal energy from the first working fluid to the fin or the second working fluid.

Abstract:

A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem is configured to receive and to thermally roast a batch of beans. The air handling subsystem is coupled to the roasting subsystem and includes a blower, a cyclone separator, and a heater. The blower is configured to impart air motion. The air passes through the air handling subsystem. The cyclone separator is configured to remove particulates from the air handling subsystem. The heater is configured to heat the air passing through the air handling subsystem. The heater includes heater windings that are incorporated into the cyclone separator.

Abstract:

A technique for planarizing build surfaces in three-dimensional printing includes the use of a three-dimensional printer having an extruder with a sensor mechanically coupled thereto, where the sensor is operable to sense a contact force between the extruder and a separate structure. In particular, the sensor may be used to measure the contact force at a plurality of locations across a build surface of the separate structure, so that a difference between the measured contact force at two or more locations can be identified. In response to the difference between the measured contact force at these locations, a control signal may be created to reduce the difference for planarizing the build surface, e.g., by fabricating a layer on the build surface that mitigates irregularities therein, by gap filling on the build surface, or by adjusting a parameter of the three-dimensional printer.

International Classification:

A23N 12/10
A23N 12/08
A23F 5/04

Abstract:

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.

Abstract:

A bean roasting system includes a roasting drum, an agitator, and a door. The roasting drum has an inside surface extending from a back end to a front end. The agitator has blades mounted to an axial shaft. The axial shaft has an anterior end portion. The door is mounted rotationally relative to the roasting drum and includes a glass plate and a bearing assembly. The glass plate provides visual access to contents inside the roasting drum when the door is closed. The bearing assembly includes an outer housing and an inner bearing. The outer housing is mounted to the glass plate. The inner bearing defines a receiving hole that receives and supports the anterior end portion of the axial shaft when the door closed.

Abstract:

A three-dimensional printer is configured to fill interior cavities of a fabricated object with functional or aesthetic materials during fabrication. In general, a number of layers can be fabricated with an infill pattern that leaves void space within an exterior surface of the object. These void spaces can receive a second material such as an epoxy or adhesive that spans multiple layers of the object to increase structural integrity. Similarly, aesthetic materials may be used to add color, opacity, or other desired properties to a fabricated object. The void spaces can also or instead form molds that are filled with a build material to provide a fabricated object.
