Patent CA-2349275-A1 (CA)
Title: Fluid filters having a concealed machine-readable identification
Inventor: HUNTER SUSANNE PHYLLIS
IPC: B01D35/00
Filed: 2001-05-31
Abstract: An intake filter (1) or a coalescing filter (4) of a compressor or vacuum pump, or an in-line filter has its identity recorded in a transponder (50, 54), memory chip or other device such as a magnetic or magnetostrictive strip. Interrogation e.g. by means of antennae (52, 56) enables a control unit (55) to verify the identity of the filter and to store the result in memory (57). A record can therefore be maintained of whether approved filters are being used and whether they are exchanged at approved intervals.

Title: Improved structure for electric lock
Inventor: HUANG TSUN THIN
IPC: E05B47/00
Filed: 2001-09-07
Abstract: An improved structure of electric lock disclosed herein employs only one electromagnetic coil and a DC power source formed of 4 3A-type dry battery unit for operating the lock instead of using two coils and an AC large power source along with a clumsy conductor layout, and a skilful arrangement of mutual positions between the driven rod and the extended portion of the actuated rod can produce an amplified driving torque effect from this minimized DC power source. Besides, the key function is controlled by a coded chip attached thereon to identify the visitor.

Patent CA-2362368-A1 (CA)
Inventor: CAPLAN MICHAEL
IPC: C07K19/00
Filed: 2000-02-10
Abstract: The disclosed method involves providing a collection of mutant polypeptides where the amino acid sequence of each mutant polypeptide differs in at least  one position from a polypeptide of interest, identifying mutant polypeptides  that exhibit less of the immune response than the polypeptide of interest, a nd identifying mutant polypeptides with less potential for eliciting an undesirable immune response that still retain the desired characteristic(s).  The collection of mutant polypeptides can be provided by mutagenizing nuclei c acid encoding a polypeptide of interest and expressing the mutagenized nucle ic acid to produce mutant polypeptides. The method is especially useful for reducing immune responses involving both linear and/or conformational epitop es on a polypeptide of interest. This is possible because the recombinant polypeptides used as substrates for mutagenesis in the method are essentiall y full length, remaining structurally similar to the polypeptide of interest a nd displaying essentially the same conformational epitopes.

Title: Identification of genes having a role in the presentation of diabetic nephropathy
Inventor: BRADY HUGH REDMOND
IPC: C12Q1/6809
Filed: 2000-02-28
Abstract: A method for identifying a gene having a role in the presentation of diabetic nephropathy comprises culturing mesangial cells in the presence of a concentration of glucose sufficient to induce differential expression, especially up-regulation, of a gene susceptible to such differential expression and identifying the gene so induced. The cells are also optionally subjected to mechanical strain and/or TGF-.beta.1 can be added to the culture medium. The differentially expressed genes can be identified by suppression subtractive hybridisation. The method has resulted in the identification of novel genes which play a role in the presentation of diabetic nephropathy. The genes can be used as diagnostic markers for diabetic nephropathy and as the basis of drug development programmes.

Title: Enhanced cordless telephone platform using bluetooth technology
Inventor: HUNDAL SUKHDEEP
IPC: H04M1/72505
Filed: 2002-01-29
Abstract: A cordless telephone implementing using a BLUETOOTH wireless bearer is presented. A BLUETOOTH voice data structure is implemented by coding the voice data at a bitrate below 64 kb/s, such that the full number of payload bits provided by the BLUETOOTH voice data structure are not required for transmission of voice data. The packet payload is then encoded in a non-standard format to implement a robust error detection and/or correction protocol for the voice data, as well as for the provision of a low-rate data channel for transmission of information such as caller ID.  Alternatively, a BLUETOOTH non-voice data structure can be employed by transmitting encoded voice data as user payload bits. The data link is then flushed each time new voice data is ready for sending by the transmitting device. If slots are available before the data link is flushed, unsuccessfully transmitted data can be automatically resent, thereby implementing time and frequency diversity.

Title: Apparatus and method for mixing a gas and a liquid
Inventor: DRESSELHAUS HELMUT
IPC: A23L3/3409
Filed: 2002-02-01
Abstract: An apparatus and method are provided for mixing a gas and a liquid to produce a gaseous vapor of the liquid that is substantially free of droplets.  Gas, e.g., carbon dioxide, is divided into first and second streams. The first stream is combined in an atomization zone with the liquid, e.g., acetic acid, to form an atomized mixture of the gas and liquid. This atomized mixture is then contacted with the second gas stream in a mixing zone within a mixing/separation chamber in which the second gas stream vaporizes substantially all of the atomized liquid, and the resulting mixture of gas, vaporized liquid and residual droplets moves to the separation zone of the mixing/separation chamber. In the separation zone, the residual droplets gravitationally separate from the vaporized mixture, and the vaporized mixture free of a substantial amount of residual droplets is removed from the chamber. A  vaporized mixture of carbon dioxide and acetic acid is useful as, among other things, a preservative for perishable products, e.g., baked goods.

IPC: B24C1/00
Filed: 2000-11-30
Abstract: An apparatus (110) is provided for removing a coating (200) from a substrate  (220), comprising a nozzle (140) having an outlet (142) and adapted to direc t a particle stream therethrough at a predetermined flow rate, a signal source  (162) for emitting a signal capable of traversing the particle stream, and a  signal sensor (164) positioned to detect the signal emitted by the signal source once the signal has passed through the particle stream. The particle stream is directed from the outlet of the nozzle toward a coating on a substrate to remove the coating from the substrate. Since the signal emitted  by the signal source traverses the particle stream before being detected, th e intensity of the signal detected by the signal sensor corresponds to a flow rate of the particle stream such that a subsequent change in the intensity o f the signal that is detected by the signal sensor indicates a change in the flow rate of the particle stream. A method of monitoring a particle flow in an apparatus used for removing a coating from a substrate is also provided.</SD OAB>
