Abstract:
A method involves inspecting/testing a refrigeration system. One or more conduits or other components cooperate with the compressor, heat rejection heat exchanger, expansion device, and heat absorption heat exchanger to define a refrigerant flowpath. The inspecting/testing method comprises placing a plurality of collars over respective joints along the refrigerant flowpath. The collars each define a space that may be exposed to one or more sensors. Based upon input from the sensors, the presence or absence of leaks at the joints is determined.
Abstract:
An insulated panel comprises an external sheet 2, an internal lining sheet 3 and an insulating case 4 between the external and internal sheets. Indicating means are provided on an external face of a male projecting part 10 of the external sheet to indicate correct alignment of the panels at the joint. The indicating means may comprise a black line 26 printed on the outwardly extending leg 20 of the male projecting part 10. When the line 26 is aligned with an edge of an adjacent pane a visual indication is provided that the joint is correct.
Abstract:
Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer includes pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.

Abstract:
A transportation refrigeration unit, which is configured to defrost the evaporator coil of an evaporator, is provided with improvements to a power transfer mechanism (218). The power transfer mechanism (218) incorporates a coupling mechanism (236) that can transfer power from the condenser fan (206) to the evaporator fan (210). In one embodiment, the coupling mechanism (236) is encapsulated in a housing (226), which forms an interior cavity for receiving a lubricating fluid therein. The interior cavity is such that the coupling mechanism (236) is immersed in the lubricating fluid.

Abstract:
Embodiments of systems, apparatus, and/or methods can provide a damper assembly for transport refrigeration systems. One embodiment can include a damper assembly including a damper door configured to operate in a first position (e.g., closed), a second position (e.g., open), and at least one intermediate position. In one embodiment, a plurality of intermediate positions can be used to controllably vary a capacity of the transport refrigeration unit, or at least one component thereof. Embodiments of systems, apparatus, and/or methods can provide a damper assembly that can be accessed though an ambient portion of transport refrigeration systems or components.

Abstract:
An insulated panel (1) for cold-stores comprises an external sheet (2), an internal sheet (3) with an insulating core (4) therebetween. The external sheet (2) and internal sheet (3) have profiled joint-forming portions which interengage on assembly of adjacent panels. Both the external sheet (2) and the internal sheet (3) are turned back to define a male projecting part (10, 11) on one side and a female recess part (12, 13) on an opposite side of a panel. Each male part (10, 11) comprises an outwardly extending leg (20) and an inwardly extending leg (21) which terminates in a clip portion (22) which is embedded in the insulating core (4) . The corresponding recesses (12, 13) are formed by similarly shaping the ends of the external and internal sheets (2, 3). The insulating core at the edges of the panel between the joint forming portions engage on assembly to provide an insulated substantially air-tight joint. The exposed section of the insulating core is of generally trapezoidal shape with a male part (30) defined at one edge and a female recess part (31) defined at an opposite edge.
