Abstract: An automated heat shrink device, useful for forming a connection between two tubular sections having a polymeric outer surface jacket, for example, a connection between two sections of a district heating pipeline, and a method of use thereof. The device is configured such that it requires minimal clearance to either side of the pipeline when being used.

Abstract: The present disclosure is directed a vehicle inspection system for carrying out vehicle inspection and providing a quote for repair of a service recipient's vehicle, the quote being provided to a service recipient at a desired location. The vehicle inspection system includes a mobile device having a computer with a processor, a display screen, and a non-transitory computer-readable storage medium. The computer-readable storage medium includes computer-readable instructions for: displaying a graphical user interface, receiving a command to initiate vehicle inspection, determining at least one current part condition associated with at least one part of the vehicle, receiving condition data associated with the at least one current part condition, receiving vehicle identification data for the vehicle, electronically communicating the condition data and the vehicle identification data to a quoting server, receiving quote data from the quoting server, and displaying a price quote associated with the quote data.

Abstract: An induction heating apparatus for use in pre-heating pipe joints. The induction heating apparatus comprises a frame for applying around the pipe joint, and an induction heating coil made from Litz cable wires.

Abstract: A hearth furnace 10 for producing metallic iron material has a furnace housing 11 with a drying/preheat zone 12 capable of providing a drying/preheat atmosphere for reducible material, a conversion zone 13 capable of providing a reducing atmosphere for reducible material, a fusion zone 14 capable of providing an atmosphere to at least partially reduced metallic iron material, and optionally a cooling zone 15 capable of providing a cooling atmosphere for reduced material containing metallic iron material. A hearth 20 is movable within the furnace housing 11 in a direction through the drying/preheat zone 12, then the conversion zone 13, then the fusion zone 14, and then the cooling zone 15.

Abstract: Apparatus for condensing hydrocarbons, such as but not limited to butane and propane, from a stream of natural gas includes as its primary components a pre-cooler assembly, a chiller assembly, a refrigerant compressor/condenser assembly, and separator assembly. In the pre-cooler assembly warm gas entering the apparatus is cooled by counter-current flow heat exchange with cooled natural gas exiting the apparatus. The chiller assembly of the apparatus the hydrocarbon stream is cooled in co-current flow heat exchange with a first refrigerant tube, carrying a first refrigerant which is itself cooled in co-current heat exchange with a second refrigerant tube disposed in coaxial relationship with the first refrigerant tube. Both first and second refrigerant tubes are disposed in coaxial relationship with an outer jacket conveying the gas stream through the chiller assembly. Condensed hydrocarbons are separated from the gas stream in the separator assembly.

Abstract: A dual-blower assembly includes a single blower housing, the single blower housing defined by a base and opposite top, a pair of opposing side walls and a pair of opposing end walls intermediate the base and the top; a pair of inlet openings in the top; a front blower and a rear blower serially packaged in the single blower housing in a same plane, each blower aligned with a respective inlet opening of the pair of inlet openings; a rear blower exhaust opening for the rear blower disposed in one of the pair of end walls proximate the rear blower; and a front blower side exhaust opening for the front blower disposed in one of the pair of opposing side walls, the front blower side exhaust opening aligned with the front blower. Both the front and rear blowers are configured to force air in a direction from the front blower to the rear blower.
