Abstract: A process for producing a polyamide from dicarboxylic acid monomer and diamine monomer comprises the steps of: (a) mixing molten dicarboxylic acid monomer and molten diamine monomer in equimolar amounts, thereby producing a molten reaction mixture; (b) flowing the reaction mixture through at least one unvented reaction vessel. The residence time of the reaction mixture in the at least one unvented reaction vessel being between about 0.01 minutes and about 30 minutes, thereby forming a first product stream that comprises polyamide and water of polymerization; and (c) flowing the first product stream through at least one vented vessel, whereby water of polymerization is removed, thereby forming a second product stream that comprises polyamide. The process can operate continuously, and there is no need to add water to the dicarboxylic acid, to the diamine, or to the reaction mixture.

Title: Finalisation in incremental garbage collectors
Inventor: HOULDSWORTH RICHARD JAMES
IPC: G06F12/02
Filed: 1999-06-23
Granted: 2003-02-11
Abstract: A data processing method and apparatus are described for mark-sweep garbage collection through stored data structures defined by data objects in a multi threading environment supporting the handling of finalisers. Pipelining of the marking (MA) and sweeping (GC) states is enabled by increasing the number of mark states M to four, namely marked, unmarked, pending or deletable. The sweeping stage GC consists of a linear sweep across the heap in which any objects with M=deletable (detected non-reachables) are deleted at point D1, whilst objects with finalisers and M=pending are placed on a finaliser queue and marked. The finalising stage executes finalisers for objects on the finaliser queue (D2). The method includes a synchronisation point (SP) where the results of the mark phase are passed onto the sweeping phase. The synchronisation point performs the following operation of rotating M for all objects; this operation converts the systems perception of the stored code indicating marked to indicate unmarked, with similar conversion for unmarked to pending, and pending to deletable. In operation, it takes two garbage collection cycles to move an unmarked object to the deletable state (D3), which is long enough to detect finaliser-reachability in the intervening mark phase.

Title: Recordable disk recording controller with batch register controller
Inventor: WU WEN-YI
IPC: G11B20/00
Filed: 2000-11-29
Granted: 2002-03-11
Abstract: In a recordable disk recording controller circuit, a data buffer manager receives a command and sends the command to a micro-controller. The micro-controller generates a set of register batches from each command and sends the register data and index of the register batch to a batch register controller. The batch register controller receives the register data and index of the register batch in a batch buffer. The batch register controller retrieves the register batches from the batch buffer and writes the master registers of an encoder controller based on the register data and index of the register batch after the master registers of the encoder controller are updated into the slave registers of the encoder controller. The encode controller generates control signals to a recording circuit depending on updated slave registers. Such control signals causes the recording circuit to record a signal representative of signal data on a recordable disk located in a recordable disk driver.
