Granted: 2004-06-08
Abstract: In chemical production processes having flammable3 substances in a reactor, the reactor is rendered inert by feeding into it an inert gas, while headspace gas is removed from the headspace of the reactor. This inert-rendering must also be maintained if the reactor must be opened during the production process. Even when inert gas locks are used, the inert-rendering can only be reliably maintained in this case with a complex instrumental determination of the oxygen content in the reactor. This expense can be avoided by establishing and maintaining a certain difference between inert gas flowrate and headspace gas flowrate removed in a defined manner, which difference is specific to the particular production factors and is determined in advance.

Title: Code amount controlling method for coded pictures
Inventor: TANAKA MITSUMASA
IPC: H04N19/103
Filed: 1996-07-17
Granted: 2000-08-29
Abstract: The invention provides a code amount controlling method wherein, when code amount control is performed in units of a GOP, data do not remain in a buffer even if data with which a moving picture comes to an end intermediately of the last GOP are compressed. A control parameter setting section gets the number of frames from among all frames of picture data of an object of compression for which coding processing has not been performed, gets the number of frames in one GOP, and discriminates from the remaining frame number and the frame number in the GOP whether or not coding processing comes to an end intermediately of the last GOP. When coding processing comes to an end intermediately of the last GOP, the last GOP and a directly preceding GOP are coupled to vary the frame structure, and an aimed code amount is calculated. Also another method wherein all aimed code amount of the last GOP is compulsorily determined making use of an aimed code amount of the preceding GOP may be utilized. Using the thus obtained aimed code amount, a Q-scale of the macroblocks is calculated and compression coding is performed.

Title: Method and apparatus for monitoring and positioning a beam or jet for operating on a workpiece
Inventor: GROSS NORBERT
IPC: B23K26/044
Filed: 1996-08-20
Granted: 2007-06-19
Abstract: In a method for monitoring and positioning a beam or jet (3) for operating on a workpiece, a first sensor (7) (eg. in the case of a beam, a seam detecting system) ahead of the beam or jet, and/or a preset value, determines the path to be followed by the beam or jet (3). A second sensor (9) behind the beam or jet (3) monitors the action of the beam or jet. The preset value, or the readings obtained by the first sensor (7) regarding a required position of the beam or jet (3), is or are compared with readings obtained by the second sensor (9) regarding an actual position of the beam or jet (3), taking account of the velocity-dependent relative displacement between the beam or jet and the workpiece. The beam or jet (3) is corrected to a basic position if the actual position deviates from the required position.

Title: Mediation of open advanced intelligent network interface by shared execution environment
Inventor: WEISSER FRANK J JR
IPC: H04M3/42
Filed: 1995-03-21
Granted: 1999-11-16
Abstract: A method of mediation of traffic across a particular interface between the Advanced Intelligent Network operated by a local exchange carrier and an outside service provider is disclosed. The particular interface is defined between an application by a non-local exchange carrier service provider for some form of enhanced telephone service requiring use of the Advanced Intelligent Network and a shared execution environment interpreter on the other side of the interface. Mediation is conducted by the shared execution interpreter that is run on a local exchange carrier operated service control point. The shared execution interpreter enforces sufficient rules so that the local exchange carrier does not require knowledge of the details of implementation of the service provider's application. The methodology defines a unique transaction identifier that is defined and known on the local exchange carrier side of the interface. A table is created carrying the unique transaction identifiers with service process identifiers generated by various service provider applications. In this way, the shared execution environment interpreter can pass messages and instructions across the interface to the service provider's application that only reference the application's internally generated service process identifier. This isolates the service provider application from unnecessary information about the operation of the network and the operation of other service providers services. Mediation rules include testing of tables to determine whether a directory number referenced in a message request from a service provider application is a customer of the service provider, whether trunk group routing requests are valid for the service providers and whether any access to, or particular levels of access to, certain network elements are authorized for the service provider requesting same.
Patent CA-2194957-C (CA)
Inventor: BENTLEY ROGER G
IPC: G01N33/34
Filed: 1995-07-18
Granted: 2001-01-02
Abstract: A method and apparatus for monitoring the fibre surface development of pulps due to the refining or beating of mechanical or chemical pulps; an optical cell, fabricated with light-transparent windows, permits an incident collimated beam of light to pass through pulp stock flowing through the cell. The beam is transmitted through a polarizing filter prior to entering the cell, and through a second, crossed, polarizing filter, on exiting from the cell. The exit beam converges onto a photodetector. A gradual variation in the mass of fibres of the pulp stock is established over a predetermined range and this produces a change in the intensity of the transmitted light. As the light intensity changes, it passes through a maximum value; this is accompanied by a similar change in the photodetector electrical output signal. The photodetector signal is fed onto a signal processor which generates an output corresponding to the maximum photodetector output value, and this represents an index of the degree of fibre surface development.
Patent CA-2202822-C (CA)
Inventor: LEITH DONALD G
IPC: F16C3/10
Filed: 1997-04-16
Granted: 2004-07-20
Abstract: A two-part electric motor shaft assembly. The assembly includes an elongated shank member which has a cavity hollowed out at one end. A cam pin has one end configured to be received in the shank cavity and secured thereto. The other end of the cam pin forms a cam surface which is eccentric with respect to a longitudinal axis defined by the elongated shank member. By utilizing a two-piece design, the shank member may be formed of a softer and less expensive material than the alloy steel used to form the cam pin since the shank member is subjected to less loading and wear. The two-part motor shaft assembly of the present invention eliminates the stress riser that occurs with application of loading to the transition joint of a single piece design.
