Title: Pressure swing adsorption air prepurifier
Inventor: LEAVITT FREDERICK WELLS
IPC: B01D53/04
Filed: 1998-12-14
Abstract: A pressure swing adsorption air prepurifier is used to remove water, carbon dioxide and hydrocarbons from a feed gas stream, such as a feed air stream, passing to a cryogenic air separation plant.  By the incorporation of a regenerative heat exchange as an integral part of the air prepurifier, the cooling effects of the desorption of water are stored and transferred so as to cool the incoming feed air stream passing to the adsorbent material within the air prepurifier.  The productive capacity of the adsorbent material is enhanced thereby.
Patent CA-2258522-A1 (CA)
Title: Hand-held motor-driven saw
Inventor: SVENSSON ANDERS
IPC: B23D57/02
Filed: 1997-06-17
Abstract: A motor saw for cutting wood or stone includes a continuous wire loop (18) which carries uniformly-spaced cutting elements (25) and which is tensioned over a saw blade (17), from a drive wheel (30) mounted in the machine housing (15) to a loop-guiding sprocket wheel (20) at the outer end of the saw blade (17), said sprocket wheel functioning as a circular saw.      As the cutting elements (25) pass over the sprocket wheel (20), they drop into recesses (28) between cog-like sprockets (27) thereon.      The sprockets (27) support and guide the wire loop with the cutting elements (25) hanging freely in cutting positions in the recesses (28) between the sprockets. In the case of a duplicated wire loop, a cog cam (51) on the sprockets penetrates between parts (18', 18") of the loop so as to prevent the freely-hanging cutting elements (25) from twisting. These cutting elements may be irregularly shaped if desired. Given an enlarged diameter, the guide sprocket wheel (20') with the aid of the saw blade (17) attains an enhanced circular-saw effect to a depth that passes beyond the centre of the guide sprocket wheel (20').

Title: A method for generating psuedo random numbers
Inventor: SUNDARAM GANAPATHY SUBRAMANIAN
IPC: G06F7/58
Filed: 1999-02-04
Abstract: The present invention is a method for outputting larger bit size pseudo-random number z; that is cryptographically secure.

In one embodiment, the present invention is a pseudo-random number generator defined by a modular exponential function xi = g xt-i mod p . The output of the pseudo-random number generator being a pseudo-random number zi comprising a j-1 bit size segment of xi. The value of j being less than or equal to m-2c (i.e., j~m-2c). In an embodiment of the present invention, the pseudo-random number zi includes the j least significant bits of xi excluding the least significant bit of xi.
Patent CA-2260973-A1 (CA)
Inventor: NAZARENKO IRINA A
IPC: C12Q1/68
Filed: 1997-07-15
Abstract: The present invention provides labeled nucleic acid amplification oligonucleotides, which can be linear or hairpin primers or blocking oligonucleotides. The oligonucleotides of the invention are labeled with donor and/or acceptor moieties of molecular energy transfer pairs. The moieties can be fluorophores, such that fluorescent energy emitted by the donor is absorbed by the acceptor. The acceptor may be a fluorophore that fluoresces at a wavelength different from the donor moiety, or it may be a quencher. The oligonucleotides of the invention are configured so that a donor moiety and an acceptor moiety are incorporated into the amplification product. The invention also provides methods and kits for directly detecting amplification products employing the nucleic acid amplification primers. When labeled linear primers are used, treatment with exonuclease or by using specific temperature eliminates the need for separation of unincorporated primers. This "closed-tube" format greatly reduces the possibility of carryover contamination with amplification products, provides for high throughput of samples, and may be totally automated.
