Title: Automated Purchasing Control System
Inventor: LANGHANS STEPHEN
IPC: G06Q20/30
Filed: 1995-05-10
Abstract: An automated purchasing control system which can be customized for a corporate customer.

IPC: B08B9/04
Filed: 1997-03-24
Abstract: A pipeline pig suitable for use in cleaning deposits and buildup from a pipeline is also particularly suited for applications wherein the pipeline has a series of bends or even right angle corners.  The pig is suitable for  bidirectional  travel,  having  front  and  rear hemispherical noses.  The pig is constructed in a manner that  facilitates  a greater degree of elongation and deformation than is possible with known pipeline pigs, while still providing the radially outward bias that is required to effectively scrape the sidewalls  of the pipeline.   A cover carries a plurality of metal studs arrayed  about  the  cylindrical  middle  portion,  and encloses an internal core.  The core is formed in a mold from a mixture of resin and ISO,  resulting in a pig having  superior  ability  to  elongate  and  deform,  if needed, while still effectively scraping the sidewalls of the pipeline.

Title: Separation of particulate from flue gas of fossil fuel combustion and gasification
Inventor: LIPPERT THOMAS E
IPC: B01D50/00
Filed: 1995-11-03
Abstract: The gas from combustion or gasification of fossil fuel contains flyash and other particulate. The flyash is separated from the gas in a plurality of standleg (81) moving granular-bed filter modules (31). Each module includes a dipleg (77) through which the bed media (85) flows into the standleg. The bed media forms a first filter bed (95) having an upper mass having a first frusto-conical surface (97) in a frusto-conical member (83) at the entrance to the standleg (81) and a lower mass having a second frusto-conical surface (101) of substantially greater area than the first surface after it passes through the standleg. A second filter media bed (110) may be formed above the first filter media bed. The gas is fed tangentially into the module above the first surface. The flyash is captured on the first frusto-conical surface and within the bed mass. The processed gas flows out through the second frusto-conical surface and then through the second filter bed, if present. The bed media is cleaned of the captured flyash and recirculated to the moving granular bed filter. Alternatively, the bed media may be composed of the ash from the combustion which is pelletized to form agglomerates. The ash flows through the bed only once; it is not recycled.

IPC: H04R23/00
Filed: 1996-02-29
Abstract: A passive acousto-optic modulator for the modulation of a light beam as a function of a variation in air pressure comprising a beam splitter arranged relative to the beam so as to produce a signal beam and reference beam, the beam splitter ideally comprising a flat interface located between two optically transparent mediums such as the end of an optic fibre located within air, the interface being arranged relative to the light modulator such that when the light beam travels through the interface, some of the light beam is able to pass through the interface to form the signal beam, the rest of the light beam being reflected back off the interface to form the reflected reference beam; a light modulator which modulates the signal beam, the light modulator comprising an approximately flat optically reflective surface capable of movement, the reflective surface being located in a position which, at rest is a predetermined distance from the beam splitter and is approximately parallel to and facing the beam splitter and a piezoelectric element, the piezoelectric element being connected to the reflective surface in such a way that when an electric potential is applied across the piezoelectric element, it causes the reflective surface to move; and conversion means to convert variations in air pressure into corresponding variations in a signal for driving the light modulator; the arrangement being such that the modulated signal beam is combined with the reference beam to produce constructive or destructive interference.

Title: A multi-purpose high speed cryptographically secure sequence generator based on zeta one-way functions
Inventor: GOLDFELD DORIAN
IPC: G06F7/72
Filed: 1996-03-11
Abstract: A method is disclosed whereby a high performance, high integrity, cryptographically secure sequence generator based on zeta one-way functions is specified for pseudorandom sequence generation, authentication, key transfer by public discussion, and message transmission by public-key encryption. The method encompasses a new one-way function with trapdoor based on Artin reciprocity in an algebraic number field. Public keys are pseudorandom sequences based on zeta one-way functions. In the simplest instance of this method, public keys are quadratic signatures, i.e. special sequences of Jacobi symbols. The generation, transfer, and sharing of private keys is a process based on the law of quadratic reciprocity. The computational complexity of the quadratic signature problem provides the foundation for the cryptographic security of this method. This new trapdoor one-way function is distinct from constructions in the prior art.
Patent CA-2216803-A1 (CA)
Inventor: MILLER KEVIN
IPC: G06F9/48
Filed: 1997-10-16
Abstract: A computer system (e.g. running under the Unix operating system) comprises a scheduler for scheduling a number of processes.  The scheduler comprises a number of Policy scheduler classes each of which performs the same scheduling algorithm, but each of which  has a separate parameter table for independently adjusting the behaviour of that scheduler class.  This gives the system administrator much more control over how groups of applications, individual applications or parts of applications are scheduled.  A Policy scheduler monitor periodically scans the processes, accessing a database to check whether each process is allocated to its required scheduler class and, if not, assigns the process to the required class.  The database consists of an alias table, which allocates mnemonic names to processes, and a workmix table, which associates the mnemonics with scheduler classes.

IPC: H05K1/09
Filed: 1997-12-19
Abstract: A line circuit module is disclosed which comprises effectively all of the required circuitry for a line card apart from mechanical components such as relays and edge card connectors. The module includes a small ceramic substrate 2.0 inches by 0.825 inches on to which surface mount components which include a heat sensitive integrated circuit and a field effect transistor are mounted to one side and thick film components which include two battery feed resistors are printed on an opposite side. Various innovative techniques are disclosed which significantly reduce compromising component thermal interactions. Heat concerns from using a small thermally conductive substrate have been managed through advantageous use of printed battery feed resistor layouts which provide for larger portions of heat to be dissipated in resistor portions removed from a heat sensitive integrated circuit than resistor portions adjacent to the heat sensitive integrated circuit. Advantageous placement of feed resistor trim links to further manage heat dissipation are also disclosed. A line card which advantageously includes the line module is disclosed.
