Abstract: An electric air heater system including a first electric air heater module. The first electric air heater module including an outer casing having an inner surface, a first end, and a second end; a refractory insulation layer in tight communication with the outer casing; an inner cavity within the refractory insulation layer; and a plurality of tubes extending through the inner cavity from the first end to the second end, the plurality of tubes each having an exterior surface. Each tube is fixed relative to the outer casing at the first end, and each tube has an electrical connection disposed at the first end. The plurality of tubes is arranged into one or more bundles of tubes, where each bundle includes two or more tubes having a plurality of fins extending radially from the exterior surface, and a heating element axially through a hollow interior of the tube.

Abstract: An inline static mixer includes an outer tube and an inner tube positioned inside the outer tube and arranged coaxially with respect to the outer tube with a space between the inner and outer tubes. The inner tube is operable to receive and convey a hydrocarbon stream and the outer tube is operable to receive and convey a diluent stream. At least one baffle extends from the inner tube toward the outer tube and through at least a portion of the space that is operable to generate a twisted diluent flow from the diluent stream. The twisted diluent flow and the hydrocarbon stream are mixed downstream of an outlet of the inner tube with the twisted diluent flow forming a boundary layer along an internal surface of the outer tube to minimize fouling from liquid or liquid droplets of the hydrocarbon stream after mixing.

Abstract: Systems and processes for external combustion air preheating for providing preheated combustion air to a furnace. The furnace systems convective heating section includes multiple heating coils for waste heat recovery. The heating coils may be used for preheating a feed (feed preheat coils), heating a boiler feed water, superheating steam, or heating or superheating a feed stream prior to the feed being fed to the radiant coil. The waste heat in the combustion gas is also used to heat a heat transfer fluid, which may be used to pre-heat combustion air or for other purposes within the plant.

Abstract: The present disclosure provides, in some examples, a method, a system, and a computer program for vectorizing a QR code with an image in an online store or platform, digitizing the QR code with associated image, printing the QR code with the image on a sublimation/heat transfer paper, placing the paper onto a fabric, loading a cutter machine with the fabric, cutting the fabric into a patch with design details of QR code, and placing the patch onto a garment.

Abstract: An expandable piñata includes a plurality of legs, each leg comprising a plurality of triangular panels hingeably connected via hinge lines, each triangular panel having a proximal end and a terminal end, the terminal ends of the triangular panels converge, and each triangular panel including an inner and an outer surface; each leg hingeably adjustable between a first, substantially flat configuration, and a second expanded configuration in which the inner surfaces of the triangular panels define a cavity; each leg further including one or more tabs hingeably connected to the proximal ends of the one or more triangular panels, and a tab connected to a triangular panel of a first leg coupled to a tab connected to a triangular panel of an adjacent leg; and a locking device connected to two of the plurality of legs and configured to maintain the plurality of legs in the expanded configuration.

Abstract: An awning drive assembly with a motor internal to an awning roll-up tube and/or the awning using the awning drive assembly. A transmission linkage is attached to a motor assembly which is at least partially inserted into the roll-up tube of the awning. The transmission linkage is a disk connected to a motor shaft and the disk has notches which engage corresponding projections within the roll-up tube, allowing the motor to deploy and retract the awning. The awning drive assembly also has a mechanism for releasably connecting the motor assembly to a support arm mounting assembly. When the means for releasably connecting is released, a spring retracts the awning, even when the motor is not operable.

Abstract: A slide-out room and awning assembly for a recreational vehicle. The assembly includes a roll enclosure for attachment to an exterior side wall of the vehicle, a roll rotationally journalled within the roll enclosure, a slide-out room for extension from the exterior side wall, an elongated trough attached to the slide-out room, and an awning fabric attached at a proximate edge to the roll and attached at a distal edge to the elongated trough. When the slide-out room is in a retracted position, the awning fabric is wrapped around the roll. When the slide-out room is in an extended position, the awning fabric is extended from the roll over a top wall of the slide-out room at a downward slope from the roll to the trough such that debris and liquid flow into the trough.

Abstract: An awning assembly adapted to automatically lower an edge of a canopy under a predetermined weight collected on the canopy to remove some of the collected weight from the canopy and thereafter return the canopy to its original position. The awning assembly includes an arm assemblies comprising a vertically extending base arm secured at the wall, a bottom arm having a first end pivotally connected to the base arm, an extended arm having a first end pivotally connected to the bottom arm and a second end supporting the awning arm, and a top arm having a first end pivotally connected to the extended arm. Another arrangement for the arm assemblies includes a rafter arm having an inner end pivotally connected to the wall and an outer end pivotally connected to the a support arm, the support arm has an outer end connected to and supporting the awning arm and an inner end removably connected to the wall.
