Abstract: Methods, devices and systems are provided for performing a random access (RA) procedure. A wireless transmit/receive unit (WTRU) may be configured to receive RA resource sets, where each of the RA resource sets is associated with a node-B directional beam, select an RA resource set from among the RA resource sets, and initiate an RA procedure based on the selected RA resource set. The RA procedure may include selecting multiple preambles which include a preamble for each resource of a plurality of resources corresponding to the selected RA resource set. The WTRU may be configured to sequentially transmit the selected multiple preambles in sequential RA transmissions, and may be configured to receive, from a node-B, in response to the RA transmissions, at least one RA response (RAR), where each of the received at least one RAR corresponds to one of the transmitted multiple preambles.

Abstract: An automatic bottle sealing mechanism is provided for use with an automatic liquid sampling apparatus of the type having a plurality of sample receiving bottles and a movable sample distributing spout for sequentially filling the bottles with liquid samples. The bottle sealing mechanism includes a cap body adapted to be fitted over the mouth of a sample bottle in place of the usual screw cap or other type of closure. The cap body includes an open throat for allowing liquids to be poured into the sample bottle, a movable closure member for opening and closing the cap body throat, and a spring loaded latch mechanism for automatically moving the closure member to a closed position in response to the movement of the sample distributing spout.
