Abstract: There is also provided an apparatus for use on an automated pipette machine for transmitting pressure changes produced by a pump on the machine to a pipette nozzle. The apparatus comprises a housing defining a chamber a first conduit and a second conduit. The first conduit extends into the chamber and has a first opening positioned in the chamber. The first conduit is fluidically connectible to the nozzle. The second conduit extends into the chamber and has a first opening positioned in the chamber. The second conduit is fluidically connectible to the pump. The first opening of the first conduit is positioned above the first opening of the second conduit. The chamber defines at least a selected volume between the height of the first opening of the first conduit and the height of the first opening of the second conduit.

Abstract: A pipette nozzle is provided for use on a movable arm on an automated pipette machine. The pipette nozzle includes a body defining a passage therethrough and having at least two seating surfaces provided on the body. The first seating surface is configured to receive and sealingly mate with a first size of pipette tip in a manner such that the first end of the passage is in fluid communication with the first size of pipette tip. The second seating surface is configured to correspondingly receive, sealingly mate and provide passage first end fluid communication with a second size of pipette tip.

Abstract: A high shock absorbing rubber composition comprises a cured blend of a conjugated diene rubber such as natural rubber or nitrile rubber with an EPDM rubber, and significant amounts of silica and optionally clay. The cured composition has low pendulum rebound properties of 20% or less, and is suitable for use as sport grips such as tennis rackets or golf grips, hand tools, lawn equipment, and the like.

Abstract: A surface coil system for single channel MRI reception comprising a coil system including a plurality of self-resonant, overlapping coil conductor sections arranged relative to one another and to anatomical regions of a patient such that a combination of regions form a desired larger region of interest, a control unit located remotely from the coil system and electromagnetically communicating therewith, having means for selectively electronically activating and deactivating each coil section to produce MRI output signals when activated, means for combining selected MRI output signals, and means for electrically connecting the coil system to an MRI system to transmit selected MRI signals to the MRI system.

Abstract: A pneumatically operated and controlled pump which is capable of maintaining its efficiency and reliability in various environments. The pump head contains a spool and sleeve valve assembly operated in response to a signal pressure. The assembly controls the cycling of the pump through a pumping phase and a pump filling phase. A timing switch on the surface controls the occurrence of the signal pressure and thus the pump cycles, at preset intervals thus eliminating any lag time between the cycles and the need for operator estimations of the cycle times. This results in a virtually closed system and self contained unit.
