Abstract: The present disclosure relates to a vortex tube for separating a working fluid into a first working fluid and a second working fluid, the vortex tube comprising: a hot end; a cold end opposed to the hot end; a vortex generator between the hot end and the cold end, the vortex generator configured to receive a working fluid, the vortex generator comprising: a vortex chamber including a bottom wall defining a bore therethrough; and a plurality of channels configured to direct the working fluid into the vortex chamber, wherein one or more of the bottom wall and the plurality of channels are configured to direct the working fluid in a vortex motion to form a first toroidal moving away from the vortex chamber and towards the hot end; and wherein a first working fluid exits the hot end and a second working fluid is turned away from the hot end and flows through the bore to exit the cold end. The present disclosure also relates to use of the vortex tube for panel and spot cooling.

Abstract: A method, device, and nozzle for dispensing cooled lubricant is provided. Lubricant is supplied to the nozzle through an inner lubricant tube. Cooled compressed gas is also supplied to the nozzle through a conduit which surrounds the inner lubricant tube. Cooled compressed gas from the conduit is introduced into a nozzle gas bore in the nozzle and lubricant is introduced into a nozzle lubricant bore in the nozzle. The cooled compressed gas and the lubricant are mixed at a junction between these bores, such that the lubricant is siphoned into the junction by the cooled compressed gas. The mixture of cooled compressed gas and lubricant are then dispensed from an aperture in the nozzle, preferably as a fine atomized mist of cooled lubricant.

Abstract: A power generation systems with solid oxide fuel cell (SOFC) and heat recovery unit (HRU) and method are provided. In accordance with one embodiment of the disclosure, a power generation system includes a partial oxidation (POX) reactor, an array of one or more fuel cell stacks and an HRU. The POX reactor is operable to generate a hydrogen rich gas from a fuel. The array of one or more fuel cell stacks includes at least one SOFC and is coupled to the POX reactor. The fuel cell stacks are operable to generate electrical power and heat from an electro-chemical reaction of the hydrogen rich gas and oxygen from an oxygen source. The HRU is coupled to the array of fuel cell stacks and operable to generate electrical power from the heat.

Abstract: A valve assembly comprising a support body (10), a plunger assembly (11) movable relative to the support body in an axial direction parallel with a longitudinal axis of the plunger assembly and said plunger assembly being angularly movable relative to the support body about said longitudinal axis, seal means (34) to provide a fluid seal between the support body and plunger assembly when support body and plunger assembly are in a first position relative to one another, bias means (43) acting on the plunger assembly in said axial direction to urge the plunger assembly in a first direction relative to the support body towards said first position, a fluid flow passage (28) to allow flow of fluid through the valve assembly when the plunger assembly has been moved relative to the support body away from said first position, said support body and plunger assembly having associated therewith respective abutment surfaces (19,31) engagable with one another to hold the valve assembly in an open state when the plunger ass

Abstract: A mobile elevator apparatus for transporting people between a ground surface and a raised landing of an adjacent structure includes a base having wheels for rollably supporting the base on a ground surface, a tower frame having a lower end mounted to the base and an upper end above the lower end, the vertical distance between the upper and lower ends defining a frame height. The apparatus includes a track secured to the tower frame and extending generally between the lower and upper ends thereof, and an elevator car coupled to the track and movable therealong between raised and lowered positions.

Abstract: A three-phase center-filled candy product. A candy material for the outer layer or shell is extruded from a first extruder and a second material which could be a chewy material, such as gum or bubble gum, is extruded as an inner layer from a second extruder. A semi-liquid center-fill material is inserted into the inner layer. The three-phase rope of material is formed into individual pieces or tablets of candy in a forming machine. Sticks can be added to form lollipops in one embodiment. The formed products are then cooled, tumbled and prepared for further processing.

Abstract: An extensible interlocking structure suitable for tower cranes, scaffolding towers and the like is of multilateral cross-section and has two sets of main members which engage one another in end-to-end relation when the structure is extended. Tie members are pivoted to the main members, with the free ends of the tie members interlocking automatically with the main members during extension to provide diagonal bracing. On retraction the members may be stored on drums or in a rack.
