Title: In-memory preprocessor for a scalable compound instruction set machine processor
Inventor: EICKEMEYER RICHARD J
IPC: G06F9/38
Filed: 1991-03-14
Granted: 1995-06-27
Abstract: A digital computer system capable of processing two or more computer instructions in parallel and having a main memory unit for storing information blocks including the  computer  instructions  includes  an  instruction compounding  unit  for  analyzing  the  instructions  and adding to each instruction a tag field which indicates whether or not  that  instruction may be processed in parallel with another neighboring instruction.   Tagged instructions are stored in the main memory.  The computer system  further  includes  a  plurality  of functional instruction processing units which operate in parallel with  one  another.   The  instructions  supplied  to  the functional units are obtained from the memory by way of a cache storage unit.  At instruction issue time, the tag fields of the instructions are examined and those tagged for parallel processing are sent to different ones of the functional units in accordance with the codings of their operation code fields.
Patent CA-2039164-C (CA)
Title: Logical event notification method and apparatus
Inventor: RUBIN DARRYL E
IPC: G06F9/46
Filed: 1990-08-08
Granted: 1996-02-20
Abstract: A method and apparatus for notifying programs that a logical event has occurred on a network.  Upon the occur-rence of a logical event in an operating program, an alert report is generated and stored in a buffer.   An alert function call  occurs,  providing the event type and a pointer to the buffer.   The alert function call reads a look-up table listing the programs or users requesting notification of events.   The look-up table provides the addresses to which notification should be sent and the type of notification requested.  The alert subroutine sends the requested event data from the buffer to the listed ad-dresses.  The alert function is completed and the operating program  resumes  operation.    Upon  receiving  the  event report, the receiving program stores it, displays it to a user, generates additional reports, or the like as directed by the receiving program.   The invention provides the advantage that each operating program need only perform a universal function call to send event data through the network and then may return to a task.   The operating program is not concerned with who receives the report or what action is taken based on the report.   The programs requesting alert data from an operating program of any type need only provide a request to an alert look-up table.  The sources of the events and requesting programs are all software controlled, providing ease in adding or modifying each.

Title: Apparatus for transferring a threading tail of a web
Inventor: WEDEL GREGORY L
IPC: D21F7/00
Filed: 1991-06-05
Granted: 1995-05-16
Abstract: An  apparatus is disclosed for transferring a threading tail  of a web from a press section to a dryer section of a papermaking  machine.   The apparatus includes a press roll for  releasably  supporting the web and a doctor blade which cooperates  with  the  press roll.  A tail cutting device is disposed upstream relative to the blade for cutting the tail from  the  web.   A lead-in roll is disposed adjacent to the press  roll.   The  lead-in roll includes a suction tail box which  cooperates with the tail.  A device moves the lead-in roll  from  a  first  to  a  second  location with the first location  being  in close  proximity to the press roll such that  when  the tail box is connected to a source of vacuum, the  tail  is  drawn  away  from the press roll onto a dryer felt extending around the lead-in roll.  The second location is  spaced  from  the  press  roll such that an open draw is established  between the press roll and the lead-in roll.  A tail  guide  is movable from a first to a second disposition with  the  first  disposition  being  such that the guide is retracted   from   contact   with   the  tail.   The  second disposition  is such that the tail guide physically contacts the  tail  for  urging  the  tail  laterally relative to the lead-in  roll  into  engagement with a threading rope system which extends around the lead-in roll.

A spring means may be provided to urge disconnection of the serial circuit when the fusible link melts.
Patent CA-2057529-C (CA)
Inventor: PARKINSON KEITH
IPC: B32B27/08
Filed: 1991-12-12
Granted: 2001-08-28
Abstract: A retortable container has a wall of at least two co-formed laminas. This wall is highly impermeable to fluids selected from the group consisting of oxygen and aromatic vapors. The wall includes a first load-carrying lamina of a first plastic material. This load-carrying lamina has been formed without mechanical hysteresis in the melt phase by a thermal pressure forming apparatus to cause strengthening with orientation of the load-carrying lamina in at least one axis but without memory of its pre-melt phase shape. The wall also includes a second sealing lamina of a second plastic material.      This second sealing lamina is coextensive with the first load-carrying lamina. Consequently, the container formed by the apparatus is retortable, i.e. it can withstand temperatures and pressures of a retort chamber without undergoing signifi-cant and permanent distortion.

Granted: 1997-03-18
Abstract: A  process  and  apparatus  for  impregnating  a  cellular material with  liquefied gas  at  a predetermined pressure for subsequent  expansion  of  the  impregnated  cellular  material including the steps of charging the cellular material into an impregnation vessel, purging the impregnation vessel with inert gas, pressurizing the impregnation vessel with inert gas to the predetermined pressure,  transferring liquefied inert gas into the  impregnation vessel  from a process vessel  in which the liquefied gas is stored at the predetermined pressure, soaking the  cellular  material  in  the  liquefied  inert  gas  for  a predetermined time  period,  transferring  unabsorbed  liquefied gas  from  the  impregnation  vessel  to  the  storage  vessel, depressurizing the impregnation vessel by venting the inert gas therefrom and removing the impregnated cellular material from the  impregnation  vessel,  the  inert  gas  used  to  purge  and pressurize the impregnation vessel being taken from a source completely independent of the liquefied inert gas contained in the process vessel.  Pressure and temperature variation in the process vessel  is minimized by using  an external  source of inert gas for the purging and pressurization steps.

Title: Process for bleaching of lignocellulose-containing material
Inventor: ANDERSSON LENNART
IPC: D21C9/10
Filed: 1992-04-27
Granted: 1996-07-23
Abstract: The present  invention relates to a process for delig-nification and  bleaching of  chemically digested lignocel-lulose-containing pulp,  where the  pulp is  treated with a complexing agent at a pH between 3.1 and 9.0, whereupon the pulp is  bleached with  ozone. The initial treatment with a complexing agent removes the ions of  certain metals detri-mental to  the subsequent  ozone bleaching, while retaining in the pulp the desirable ions, primarily of alkaline earth metals. Thereby,  the selectivity in the delignification is increased and the strength of the pulp maintained. The pulp can be  bleached with peroxide before the ozone step and/or after the treatment according  to the  invention, to obtain the desired final brightness and completely avoid formation and discharge of chlorinated organic compounds.

Title: Noise cancellation arrangement
Inventor: ROSENTHAL FELIX
IPC: A61B5/344
Filed: 1992-10-09
Granted: 1996-12-10
Abstract: Information collected from the primary sensor and a plurality of the reference sensors is compared to derive correlation  data.  A matric, representing correlation data in the time  domain or cross-spectral density information in the frequency domain, is constructed based on the computed correlation  data. The matrix is transformed to a diagonal matrix and a threshold value is selected with reference to one of the larger  eigenvalues of the diagonalized matrix.  Components of the diagonalized matrix are compared to the threshold and values greater than the threshold are used together with primary sensor correlation data to compute Wiener filter constants.  The reference sensor outputs are modified by the filter constants and modified sensor outputs are substracted from the primary sensor output. A noise-cancelled output signal is then synthesized.
