Abstract: A media library includes a library housing, a heat-producing device, one or more storage media and an air mover assembly. The library housing can include a library interior where the library interior can include a first wall and a second wall positioned opposite the first wall. The heat-producing device can be positioned near the first wall of the library interior. The one or more storage media can be positioned in the library interior between the heat-producing device and the second wall. The air mover assembly can be is configured to move air into the library interior through the first wall and out of the library interior through the second wall. The heat-producing device can include one or more of a media drive, a power supply and a controller. The air mover assembly can move air through the heat-producing device before the air moves through the one or more storage media.

Abstract: A tape cartridge for use in one or more tape drives of a tape library includes a cartridge housing and a magnetic tape. The magnetic tape is retained within the cartridge housing. The magnetic tape includes a first tape section that is pre-recorded with calibrated data for evaluating data durability on the magnetic tape. The magnetic tape is usable within the tape library to measure a health of the one or more tape drives and/or confirm a suitability of an operating environment within the tape library in terms of at least one of temperature and humidity. The calibrated data in the first tape section can be further configured for evaluating total transverse dimensional stability on the magnetic tape. The first tape section can include predetermined error patterns to assist in evaluating the data durability on the magnetic tape and/or periodic tape scrubbing operations to enhance data durability on the magnetic tape.

Abstract: A retrieval assembly (22) for moving storage media (16) within a media library (10), the media library (10) including a rack assembly (20) having a first rack (20A) and a spaced apart second rack (20B), comprises a picker system (32), an assembly base (30), a first mover (28A), a second mover (28B), and a control system (26). The picker system (32) selectively engages the storage media (16). The assembly base (30) supports the picker system (32). The first mover (28A) is secured to the assembly base (30), and selectively moves along the first rack (20A). The second mover (28B) is also secured to the assembly base (30), and selectively moves along the second rack (20B). The second mover (28B) is spaced apart from the first mover (28A). The control system (26) controls independent movement of the first mover (28A) and the second mover (28B) to position the assembly base (30) relative to the storage media (16).

Abstract: A storage media retrieval assembly (22) for moving storage media (16) within a media library (10) including a library housing (12), comprises a picker system (32), an assembly base (30), and a first sensor (240A). The picker system (32) selectively engages the storage media (16). The assembly base (30) supports the picker system (32). The assembly base (30) is movable relative to the library housing (12). The first sensor (240A) senses if the assembly base (30) is level relative to the library housing (12). Additionally, the retrieval assembly (22) can further comprise a mover (28) that is secured to the assembly base (30), the mover (28) selectively moving the assembly base (30) relative to the library housing (12). In alternative embodiments, the first sensor (240A) or a second sensor (238A) can be a home sensor that senses a home position of the mover (28) relative to the library housing (12).

Abstract: A flame management system comprises two flame detector units which are arranged to view different regions of at least one flame and are connected to separate channels of a processor. Each detector unit has at least two operating modes, such as an infra-red and an ultra-violet operating mode, or a normal and a sensitive infra-red or ultra-violet mode, etc. and is switchable between those modes by the processor. The processor thus selectively processes the output of the two units and actively controls the operating mode of each to obtain responses appropriate to the type and/or condition of the or each flame being monitored. In order to enable both IR and UV monitoring from a single detector unit, the detector includes at least one photo-sensitive member together with an optical element such as an IR filter which operates selectively to deliver an undivided IR or an undivided UV compact to the at least one photo-sensitive member.

Abstract: An oil flame monitoring system has an ultraviolet flame detector 1 and an infra red Flicker flame detector 2. The UV flame detector views a region 11 of the flame 5 known as the primary combustion zone which is situated about 1 to 2 metres downstream of a fuel atomizer 4. The IR Flicker flame detector 2 views a region 3 of the flame 5 inside the fuel oil spray just downstream of the fuel atomizer 4. A programmable logic controller processes the outputs of the two detectors 1, 2 and provides information about the position of the flame front and the quality of the flame.

Abstract: A tip shut-off fluid injector F has its injection device 1 inset to a fixed female interlocking terminal 2 when in the firing position with which a change-over valve 4 is connected by pipes P or is made integral. The terminal 2 includes valves 8 and 9 and, optionally, a by-pass valve 10. A gearbox 12 connects between the valves 8, 9 and 10 and a handwheel 11. Rotation of the handwheel 11 inserts or retracts the injection device 1 to or from the firing position and also, via the gearbox 12, rotates the valves 8, 9 and 10 between open and closed positions. Before the injection device 1 can be retracted, the handwheel 11 must be initially rotated to rotate the valves 8 and 9 to closed positions to isolate the fluid supply from the injection device 1 and, optionally, to open the by-pass valve 10 to allow fluid to circulate from the supply through the terminal 2 back to return.

Abstract: The invention comprehends a fluid injector comprising a liquid supply path to discharge passage means, a liquid return path for liquid supplied through the liquid supply path but not discharged through the discharge passage means, and a gaseous supply path to the discharge passage means and having a region in common with the liquid supply path, by which effecting a variation as between the liquid and gaseous pressures in said region will result in variation in the discharge of liquid from the fluid injector.
