Title: Pipetting device
Inventor: THOMAS NICHOLAS
IPC: G21F7/06
Filed: 1993-03-26
Abstract: An automatic device has a pipette (46) which is movable by motors along a guided path (48) between first and second locations at which a supply and storage vial (43) and a rack (45) for carrying one or more receptacle tubes (44) are respectively positioned.

Patent CA-2121221-A1 (CA)
Inventor: RYAN CHARLES P
IPC: G06F12/08
Filed: 1994-04-13
Abstract: In a data processing system which employs a cache memory feature, a method and exemplary special purpose apparatus for practicing the method are disclosed to lower the cache miss ratio for called operands. Recent cache misses are stored in a first in, first out miss stack, and the stored addresses are searched for displacement patterns thereamong. Any detected pattern is then employed to predict a succeeding cache miss by prefetching from main memory the signal identified by the predictive address. The apparatus for performing this task is preferably hard wired for speed purposes and includes subtraction circuits for evaluating variously displaced addresses in the miss stack and comparator circuits for determining if the outputs from at least two subtraction circuits are the same indicating a pattern yielding information which can be combined with an address in the stack to develop a predictive address. The efficiency of the method and apparatus is improved by providing pattern detection logic circuitry for searching for a plurality of patterns simultaneously and priority logic circuitry which establishes precedence in the event that more than one pattern is sensed with a given set of recent cache misses.

Title: Method and apparatus for testing a spring-loaded safety valve
Inventor: KUEHN EDMUND
IPC: F16K37/00
Filed: 1994-05-05
Abstract: A method for testing a spring-loaded safety valve includes ascertaining a closing pressure of the safety valve by selecting a pressure of a medium acting on a closing device of the safety valve to be less than an expected closing pressure. The closing device is lifted with a force origi-nating at an auxiliary lifting device by acting upon a chamber below a lifting bell in the lifting device with an auxiliary medium. Then the safety valve is closed by divert-ing the auxiliary medium out of the chamber and simultaneous-ly a supply of auxiliary medium is passed through the chamber and diverted. Pressures of the medium and of the auxiliary medium are measured as the safety valve is closing. The closing pressure is determined from the measured pressures, from an effective area ratio of the lifting bell and a valve plate of the closing device, and from a constant, in accor-dance with the equation:        P S = P P + (P H .cndot. V A)/(m + 1).   wherein P S is the closing pressure of the safety valve, P P is the measured pressure of the medium acting upon the closing device in the closing process, P H is the measured pressure of the auxiliary medium acting upon the lifting bell in the closing process, V A is the ratio of the effective area of the lifting bell and the closing device, and m is a constant. An apparatus for testing the safety valve is also provided.

Abstract: A synchronous voice/data messaging system allows parties to communicate both voice and graphic information or  other  data  interactively  or  to  retrieve  such information synchronously in the exact sequence in which it was created.  Voice information and data information are transmitted on a voice channel and a data channel. Time stamps are generated to synchronize the voice and data information.   The time stamps can be generated either in a user device or in a multimedia messaging system.  In either case, the voice and graphic or other data is played back to the called party in the exact sequence and at a rate corresponding to the rate at which it was received.   Such a system can also be used to provide other services such as synchronous voice/data messaging while on hold or as part of a multimedia greeting.
