摘要:
The invention provides an apparatus for supercritical fluid chromatography. The apparatus comprises a binary pump; an autosampler; a sampling valve; a first and second port switching valve; a first and second manifold; two or more channels, each having a check valve assembly, a separation column and one or more detectors operatively connected thereon; and a backpressure regulator. The apparatus also includes computer software and hardware to control distribution of fluid through the apparatus, including switching between a multi-channel mode or a single channel ode; 2) analyze data collected by the one or more detectors; and 3) optimize separation of analytes by controlling solvent combinations, concentration gradients, pressure and temperature. The apparatus excludes additional backpressure regulators or pumps on individual channels. Also provided is a method of screening a sample, using supercritical chromatography, using the above apparatus, where multiple samples can be screened simultaneously with parallel processing.

An adapter is used to allow beer to be dispensed from a single keg to a plurality of containers simultaneously. The adapter includes a connector for attaching the adapter to the keg tap spout. It further includes a separator for dividing a fluid flow from the keg into a plurality of flows. A plurality of spigots are connected to the separator for controlling flows into the plurality of containers.

A clamping device having a front member, a back member opposing the front member, a pair of opposing side members, a stop block and a clamping mechanism. The side members extend between and connect the front member and the back member. The work piece is supported by and between the side members. The stop block is interposed between the back member and the work piece. The clamping mechanism, which is operatively coupled between the front member and the work piece, exerts a clamping force against the work piece to press the work piece against the stop block. In this way, the work piece is clamped between the front member and the back member.
摘要:
A, preferably external, storage device is provided with a button or other user input which, when activated, causes a launch of an application such as a backup of data from the host device onto the external storage device. Preferably, the external storage device includes a hard disk drive. Communication with the host device can be made using USB, IEEE 1394, Ethernet, wireless links or other links. The external device is configured to allow the host to become aware of a button press, e.g., by a notification or interrupt technique, or by a polling technique.
摘要:
A containment device is described which has been developed for use on stairlift chairs, but may have a variety of other applications. The containment device includes a belt (26) retractably wound onto a reel. The reel is, in turn, mounted in a carrier (28). In operation, the carrier (28) is displaced to a locking point, the act of displacement unwinding the belt from the reel. When the carrier (28) is locked in position the belt (26) is locked with respect to the reel. Other features, particularly relevant to stairlift applications, are described.
摘要:
A health food product containing a first component in the form of a discrete portion from a second component provides enhanced in vivo oxidative defense indices and prevents or attenuates exercise-induced in vivo oxidative stress as indicated by cellular and/or tissue modification. The first component includes an antioxidant mixture containing a blend of antioxidants selected from all-trans beta-carotene, a mixture of cis beta-carotenes, all-trans alpha-carotene, a mixture of cis alpha-carotenes, all-trans lycopene, a mixture of cis lycopenes, all-trans gamma-carotene, a mixture of cis gamma-carotenes, zeta-carotene, phytofluene, phytoene, vitamin C, vitamin E and curcumin. Internalization and integration of the above nutrients within a lipid containing core of the food product facilitates absorption of the fat-soluble components in the gastrointestinal tract following consumption, increases shelf-life and minimizes degradation of these labile compounds by minimizing exposure to heat, light and/or oxygen, and prevents disadvantageous yellow/orange coloration of the outer material of the food product.
