Abstract: A method and apparatus are provided for delivering items to a plurality of storage locations. The items are fed into the apparatus at an input station having a scanning station. The scanning station evaluates one or more characteristics of each item. The items are then loaded onto a delivery mechanism that delivers the items to storage locations. Once at the appropriate storage location, the delivery mechanism discharges the item to the storage location and returns to receive another item to be delivered.

Abstract: Disclosed within are various methods for adjusting height and rotation of a spray gun used in a line striper via a graphical user interface (GUI) in a control device.

Abstract: A method for venting a spray-cooled roof of a ladle metallurgical furnace is provided herein. The method begins by processing molten metal materials in a ladle metallurgical furnace having a spray-cooled roof with an opening configured for one or more electrodes to pass there through and an integrated hood. Process gases and fumes are extracted through a channel having walls disposed within an enclosed space of the spray-cooled roof. The walls of the channel are cooled with a spray-cool system extends between the walls of the channel and a top of the spray-cooled roof.

Abstract: The present disclosure provides systems and methods for sample analysis. The system comprises a container. The container comprises a sample receptacle and a cap, and the cap comprises a reservoir for retaining a composition, a first piercing member and a first pierceable barrier for sealing said composition within said reservoir. There is also provided a method for sample analysis.

Abstract: Presented are RNA nucleotide sequences referred to as EXO-Codes, and longer RNA polynucleotides that contain the EXO-Codes. EXO-Codes provide RNA with the ability to a) be selectively sorted to extracellular vesicles such as exosomes, and b) deliver a variety of cargo types to program or reprogram the extracellular vesicles, and cells that receive the exosomes. Also presented are methods of making the EXO-Codes, modifying cells using the EXO-Codes, expression vectors encoding the EXO-Codes, and exosomes and other secreted vesicles that include RNA polynucleotides that contain the EXO-Codes.

Abstract: An apparatus is disclosed for a metallurgical furnace having a roof with an integrated off-gas hood. The roof has a hollow metal roof. The hollow metal roof has a top, a bottom, an outer sidewall and an inner sidewall. An opening extends from the top to the bottom and is defined by the inner sidewall. The opening is configured for one or more electrodes to pass therethrough. An enclosed space is defined between the top, the bottom, the inner sidewall and the outer sidewall. A spray-cooled system is disposed in the enclosed space and configured to spray coolant in the enclosed space on the bottom surface of the hollow metal roof. A channel having walls is disposed through the enclosed space, wherein the spray-cooled system extends between the top of the hollow metal roof and the wall of the channel.

Abstract: One embodiment is a cooling system for regulating temperature of a surface of a metallurgical furnace. The cooling system includes a plurality of spray conduits. Each spray conduit has one or more control valves and has a plurality of nozzles. A plurality of temperature sensors are disposed proximate the surface of the metallurgical furnace. A control system adjusts the control valves of the plurality of spray conduits in response to temperature information derived from the plurality of temperature sensors.

Abstract: Disclosed herein is a metallurgical furnace and roof having a drain system. The roof has a roof body comprising a top surface having a center opening, a bottom surface opposite the top surface, and an outer sidewall connecting the top surface to the bottom surface. The outer sidewall, the bottom surface and the top surface define an interior portion. An internal spray cooling system is disposed in the interior portion of the body. A drain system is integral with the body. The drain system has a roof evacuation conduit disposed outside the interior portion and configured to collect spay coolant from the interior portion of the body. The drain system additionally has a drain box having a vent and an exit pipe, wherein the roof evacuation conduit channels spent coolant by gravity into the drain box which is evacuated under gravity by the exit pipe.

Abstract: An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

Abstract: An apparatus for collecting, diluting and dispensing a predetermined volume of a patient fluid sample, such as blood, into the collection port of a point-of-care diagnostic test. The apparatus is constructed and arranged to collect a predefined volume of fluid sample by wicking, to mix the whole blood with a dilution reagent, and to dispense a predefined volume (within predefined tolerances) of diluted fluid sample into the collection port of the POC test kit. The apparatus has an elongate body with an internal cavity and a capillary tube in fluid connection with the internal cavity. A mixing valve separates the capillary tube and the internal cavity and selectively opens and closes the fluid connection between the capillary tube and the internal cavity. A plunger reciprocates within the valve body between a retracted limit position and a distal limit position for creating negative and positive pressure within the internal cavity.
