A cassette for steam sterilizing of instruments comprises a lid and a tray, the tray having an inlet and an outlet for the cassette for communication with a sterilization apparatus, and the lid having a seal configured to interface with the tray to maintain either pressure or vacuum conditions for an interior of the cassette. The seal is configured to allow the lid to move between a vacuum position and a pressurized position without exposing the cassette interior to an outside environment. The inlet and outlets have two sets of valves and seals that ensure that the cassette interior remains sterile after the sterilization process is complete and during cassette storage. One set of valves also allows access to the cassette interior for the steam sterilization cycle.

Cassette for vacuum and steam sterilization apparatus

A sterilizer for medical instruments is compact and designed to be placed on a table top. The sterilizer provides includes a cavity for receiving a cassette holding the instruments to be sterilized. A stream circuit provides steam to the cassette for sterilization, and the time required for sterilization is reduced by withdrawing air from the cassette by application of a vacuum. The cavity is evacuated at the same time as the cassette to prevent application of high stresses to the cassette during the vacuum-assisted withdrawal of air. The time for sterilization is further reduced by use of dual heat exchangers to reduce the volume removed from the cassette.

A modular split-axis stage is used to inspect and/or repair large flat glass media suitable for LCD/TFT applications. Low-precision air table sections are detachably mounted to a centrally located, high-precision granite inspection/repair section. Glass media held by a vacuum contact is transported on air cushions from the up-web air table to the central inspection/repair section. Vacuum nozzles integrated with porous medium pads precisely control the height of the flexible media above the central section during inspection or repair. Embodiments includes structures in which the media is either stationary or moving during inspection/repair. A first media can be loaded/unloaded while a second media is undergoing inspection or repair in a pipelined operational mode.

A photocuring device and a method of photocuring using it. The device includes a housing and a light emitting semiconductor array mounted to the housing, capable of emitting light energy having a light output wavelength suitable for initiating a photoreaction. The device also has a power source for providing power to energize the array to emit light energy and a controller coupled to the power source for varying the power provided by the power source to the array.
