Abstract: A method and apparatus for separating air in which an argon refining column of a distillation column system is reboiled with a liquid air stream. The argon refining column further refines crude argon produced by a crude argon column connected to a lower pressure column of the distillation column system. At least one intermediate reflux stream is formed, at least indirectly, from at least part of the liquid air stream, and is introduced into the lower pressure column at a level thereof above where a crude liquid oxygen column bottoms of a higher pressure column of such system is further refined to increase a liquid to vapor ratio below said level and therefore, argon recovery from the argon refining column.

Abstract: A compactor/baler for compacting materials includes a frame defining a compacting chamber, a platen movably mounted to the frame, a loading gate movably mounted to the frame and a control panel including a biometric reader having a biometric scanner. The platen is movable within the compacting chamber and the loading gate is movable from a closed position blocking access to the compacting chamber and an open position exposing the compacting chamber. The control panel is actuable between a locked configuration and an operational configuration. The biometric reader is designed to accept a biometric attribute of a user and to actuate the controller between the locked and operational configurations. The biometric reader actuates the controller to the operational configuration if the biometric attribute matches a stored biometric attribute. The control panel prevents the loading gate from moving to the open position when the controller is in the locked configuration.

Abstract: A castor control unit for a swivel castor has a plurality of selectable modes of operation. The modes of operation include at least a free mode, in which the castor (14) can freely swivel about a swivel axis (26) and a wheel or wheels (30,32) of the castor can rotate about a rolling axis (28), and a direction lock mode, in which the castor is locked against swivelling about the swivel axis and the wheel or wheels of the castor can rotate about the rolling axis. The castor control unit (70) comprises a measuring means (154) for measuring motion, a processing means (150) that deduces, from the measured motion, whether there is a need to engage or disengage the direction lock mode, and an actuating means (120a) for actuating the castor to engage or disengage the direction-lock mode of operation. The actuating means is controllable by a control signal, and the control signal is determined, at least in part, from the deduction of whether there is a need to engage or disengage the direction lock mode.

Abstract: Separation method and apparatus for separating a gaseous mixture, for example, air, in a cryogenic rectification plant in which a compressed stream is divided into subsidiary streams that are extracted from a main heat exchanger of the plant at higher and lower temperatures. The two streams are then combined and expanded in a turboexpander to generate refrigeration for the plant. The flow rates of the two streams are adjusted to control inlet temperature of a turboexpander supplying plant refrigeration and to minimize potential deviation of the turboexpander exhaust from a saturated vapor state. Control of the expansion ratio can advantageously be applied to allow variable liquid production from the rectification plant.

Abstract: A method and apparatus for producing an oxygen product in which air is separated in an installation including air separation units having higher and lower pressure columns. A pumped liquid stream generated within the installation, that can be a pumped liquid oxygen stream, is warmed within a main heat exchanger through indirect heat exchange with a compressed air stream to produce a liquid air stream. An impure oxygen stream is rectified within an auxiliary column to produce an oxygen containing stream that is introduced into the lower pressure column of each of the air separation units and intermediate liquid streams, composed of the liquid air stream or another air-like stream, reflux the lower pressure columns and the auxiliary column and optionally the higher pressure column of each of the air separation units.

Abstract: Methods, systems and computer-readable storage media relate to determining individualized treatment planning margins. The methods may include processing motion data of a target obtained from at least one marker for one or more periods. Each period may include a plurality of time intervals. The processing may include processing the motion data to determine an isocenter for each time interval along at least one of the axes of motion. The axes can include the x axis, the y axis, and/or the z axis. The method may include determining motion prediction data for each of the at least one of the axes; and determining treatment planning margins for each of the at least one of the axes based on the motion prediction data. The individualized treatment margins can be smaller and more optimal because the treatment margins can incorporate patient specific patterns of motion of a target (e.g., an organ).

Abstract: Air separation method in which air is separated within cryogenic rectification processes conducted in first and second cryogenic air separation plants. The first cryogenic air separation plant is designed to produce an oxygen-rich product stream and the second cryogenic air separation plant is designed to produce an impure oxygen vapor stream. At least part of the impure oxygen vapor stream is introduced into a lower pressure column of the first cryogenic air separation plant and oxygen contained in such stream along with air separated within the first air separation plant is used in producing the oxygen-rich product stream.

Abstract: A method of producing a liquid product stream, for example, a liquid nitrogen product stream, at a production rate that is selectively varied. This variation is produced in either a waste expansion or air expansion process by increasing the pressure and flow rate of the feed stream during periods in which a high rate of liquid production is desired without substantially increasing the pressure of the exhaust stream produced by a variable speed turboexpander. This increases the expansion ratio across the turboexpander and therefore the refrigeration supplied to increase liquid production. At the same time, the increase in flow rate prevents a decrease in the performance of the variable speed turboexpander.

Abstract: A method and apparatus to produce oxygen and nitrogen co-products in which a compressed a compressed and purified air stream is cooled, fully or partially condensed and then rectified in a main distillation column to form a nitrogen-rich vapor column overhead and crude liquid oxygen. A crude liquid oxygen stream is depressurized and then stripped in an auxiliary distillation column with a stripping gas to produce an oxygen-rich liquid. The nitrogen-rich vapor column overhead from the main distillation column is used to form a nitrogen product and the crude liquid oxygen is partially vaporized to produce the stripping gas, a residual oxygen-rich liquid and liquid nitrogen reflux to the main distillation column. The oxygen product is formed from the residual oxygen-rich liquid by either providing the heat exchange duty in condensing the compressed and purified air stream or by condensing nitrogen-rich vapor used in refluxing the main distillation column.

Abstract: A cryogenic air separation method and apparatus in which a lower pressure distillation column is configured to receive, at successively higher locations of the lower pressure column and at successively lower temperatures, crude oxygen derived from a crude liquid oxygen stream discharged from a higher pressure column, an intermediate reflux stream and a nitrogen-rich reflux stream. All of the streams are subcooled and depressurized. The subcooling is conducted such that the intermediate reflux stream and the nitrogen-rich liquid stream cocurrently, indirectly exchange heat to a nitrogen-rich vapor stream withdrawn from the lower pressure column and the intermediate reflux stream is subcooled to a temperature between the temperatures over which the nitrogen-rich liquid stream is subcooled. Additionally, the crude liquid oxygen stream and the intermediate reflux stream can, cocurrently, indirectly exchange heat to a pressurized liquid stream used in forming an oxygen product and the nitrogen-rich vapor stream.

Abstract: The present invention relates to a method and apparatus for producing a pressurized product stream product by cryogenic rectification. A main heat exchanger, used in the cryogenic rectification, warms a pumped product stream composed of oxygen-rich or nitrogen-rich liquid and thereby produces the pressurized product stream. Layers of the main heat exchanger are designed such that a reduction in the heat transfer area provided within the main heat exchanger for warming the pumped product stream occurs at a location at which the temperature of the pumped product stream exceeds either the critical or a dew point temperature of such stream. The reduction in heat transfer area leaves regions of the layers able to heat or cool another stream that is used in connection with the cryogenic rectification. Such other stream can be a refrigerant stream that allows the introduction of additional refrigeration to increase production of liquid products.
