摘要:
A beverage preparation apparatus for preparation of a beverage from a capsule in a clamp assembly (30). The clamp assembly has a first clamp member (31) and a second clamp member, where the inner surfaces of the first clamp member and the second clamp member form a clamp chamber (33) for substantially enclosing and supporting a capsule (10) during beverage preparation. The second clamp member comprises a rigid peripheral frame (32) having a central void and a resilient layer (37) extending across said central void. There is a piston (36) positioned in the central void and resiliently coupled to the peripheral frame (32) to allow limited resilient movement of the rigid peripheral frame (32) relative to the piston (36).
摘要:
A beverage preparation capsule containing a beverage preparation ingredient, having a body with side walls formed from one or more substantially air- and liquid-impermeable sheet materials defining a chamber containing a beverage preparation ingredient and further defining an outlet channel having an upstream end in fluid communication with the chamber for escape of beverage from the chamber. At least a region of the outlet channel is filled by a filtration material for filtering the beverage escaping from the chamber. Also provided is a clamp assembly for preparing a beverage from such a capsule, the clamp assembly comprising two or more clamp members, wherein an inner wall of at least one of the clamp members comprises a concave base surface for receiving the capsule and one or more pressure pads projecting from the concave base surface for selectively constricting a region of the capsule. Also provided are a beverage preparation apparatus and system comprising the clamp assembly, and a method of preparing a beverage from the apparatus.

A microkeratome blade for use for the removal of the epithelial layer and underlying Basement Membrane while leaving a smooth and undisturbed Bowman's Membrane in preparation for a laser refractive surgical procedure. The blade is capable of cutting through the epithelial layer and Basement Membrane, but not capable of cutting through Bowman's Membrane.

A thermal imaging apparatus includes an internal drum for supporting a receiver material and a donor material in a superimposed relationship, an imaging unit for thermally transferring an image from the donor material to the receiver material, and a material dispensing mechanism for dispensing the receiver and donor materials from a plurality of material supply rolls. A rotatable material supply carousel having a plurality of supply stations for supporting the plurality of supply rolls is provided. A drive system rotates the carousel to sequentially position a selected plurality of the supply stations at a dispensing position.

A dual buffer internal to an imaging device uses a one-way, over-running clutch system to buffer multiple sheets of media between an internal drum recorder and a processor. The one-way over-running clutch system is incorporated into a drive system of a plurality of rollers that transport the media. An input set of rollers and an output set of rollers are driven independently to allow for two sheets of media to be buffered simultaneously and at different speeds if desired. The buffer is mounted pivotally within the imaging device to allow access into the imaging device and to allow installation of a take-up cassette as an alternative to the buffer.

A cooling system comprises a first fan operable to push air to a device, where the air pushed forms an air column, a second fan adjacent to the device, and operable to pull air from the device, and a guide coupled to the first fan and the device and operable to guide the air column from the first fan to the second fan.

A conventional imagesetting system includes an imagesetter for transferring an image onto media, a wet chemical processor for processing the imaged media, an enclosed dryer section for drying the media by circulating air thereabout, and extraction rollers for extracting the media from the enclosed dryer section. An improved imagesetting system further includes: an apparatus for drying and lifting the media after extraction from the enclosed dryer section by blowing air along an underside of the extracted media; a stacking surface for stacking the extracted, dried media, where the stacking surface is formed by one or more external surfaces of the imagesetter and the processor and the stacking surface has at least one sloped section; and an indent which extends the stacking surface beneath the extraction rollers in a direction opposite to a direction of movement of the media being extracted, so that the indent prevents binding of trailing edges of the media by accepting sections of the media which abut the trailing edges onto the stacking surface proximate to the indent.

A media transport bridge is an integral media transport device within an internal drum laser imagesetter that transports media from an imaging area in the drum to an external processor or intermediate buffer. Five pairs of rollers transport the film over the drum. A first stage of the bridge includes a first pair of rollers driven independently so that the first stage is removable and replaceable with a take-up cassette if desired. A friction drive within the imagesetter is adaptable to drive either the first stage or the take-up cassette when installed. Upon removal of the first stage, an automatic adjustment of the bridge is performed to balance the pivotally mounted bridge. The media is moved into the bridge by a pair of drum rollers while the first stage is synchronized with the other four pairs of rollers in the bridge and monitored to keep a slack loop of media at the first stage rollers to eliminate perturbations in the media. A mechanical flag sensor changes state to slow and speed up the bridge rollers to maintain the slack loop.
