Title: Method for producing mixed metal oxides and metal oxide compounds
Inventor: PROCHAZKA JAN
IPC: C01F17/00
Filed: 2001-09-05
Abstract: A process to produce mixed metal oxides and metal oxide compounds. The process includes evaporating a feed solution that contains at least two metal salts to form an intermediate. The evaporation is conducted at a temperature above the boiling point of the feed solution but below the temperature where there is significant crystal growth or below the calcination temperature of the intermediate. The intermediate is calcined, optionally in the presence of an oxidizing agent, to form the desired oxides. The calcined material can be milled and dispersed to yield individual particles of controllable size and narrow size distribution.

Patent CA-2422203-A1 (CA)
Title: Tone detection for integrated telecommunications processing
Inventor: BIST ANURAG
IPC: H04Q1/46
Filed: 2001-09-05
Abstract: Disclosed is an integrated tone detection processor for discriminating between tone and voice signals and determining the tones. The tone detection processor performs Automatic Gain Control (AGC) to normalize the power of the tone or voice signal. Further, the energy of the tone or voice signals are determined at specific frequencies utilizing a Goertzel Filter process. The tone detection processor determines whether or not a tone is present, and if a tone exists, determines the type of tone. Based upon determining the two maximum energy levels of the Goertzel filtered tone, whether the tone is a single tone, dual tone, silence, or other (e.g. speech) can be discriminated. The tone can then be identified by a user-defined dictionary of tones. Based upon various ON and OFF cadence checks in combination with the use of TONE ON and TONE OFF counters, tones can be declared.

Filed: 2002-08-19
Abstract: Antigen-specific antibodies of enhanced sensitivity and specificity to target bacterial antigens selected from among lipo-polycarbohydrate antigens, antigens comprising lipoteichoic acid or teichoic acid or a derivative of either and capsular carbohydrate antigens may be obtained by (1) extraction from a culture of known gram-negative or gram-positive bacteria of the target antigen containing not more than 10% protein by weight, (2) coupling the conjugate to an affinity column, passing raw polyclonal antibodies to the target antigen or an IgG cut thereof over the affinity column and eluting from the column purified antibodies specific to the target antigen.     A rapid immunochromatographic test is described in which the thus purified antibodies are used to detect in a mammalian bodily fluid the target antigen or the bacterium from which it was extracted. Use of the the purified antibodies in any known test for the purpose of detecting the presence or absence of target antigen (or target bacterium) is further contemplated.

Title: Digital video recording system
Inventor: ORTH JEFFREY
IPC: H04N5/77
Filed: 2002-03-12
Abstract: A digital video recording system (10) includes a video camera (12) directed at a scene of interest to continuously view the scene and generate video images (F) of the scene. An image processor (14) is configured to compare the video image (F) with a previously established reference image (Fr) of the scene to determine if changes have occurred. The image processor includes a memory (2 0) in which portions of video images (F) are stored, together with the time and date information as to when the image was acquired. A video playback capability (30) allows the memory to be accessed to retrieve the portions of the video images for image reconstruction. The playback system enables the memory to be accessed at any desired date and time location so an image of interest can be reconstructed without having to scan stored video images in a date/time sequence. Accessing the memory is done without interrupting the image processor's processing of currently acquired video images.

Title: Push-up exerciser
Inventor: WILLIAMS GORDON
IPC: A63B23/12
Filed: 2003-09-15
Abstract: This invention relates to an exercise apparatus and in particular to an exercise apparatus designed for performing a variation of a push-up. There are a number of apparatuses presently described in patent literature. An example, which most closely resembles the invention herein, is described in United States Patent No. 4171805, issued to T. Abbott on October 23, 1979. The problem with said apparatus is that the exercises performed are limited by rolling handles confined by a complex track system. The object of the present invention is to overcome the above-mentioned problem by providing a relatively simple apparatus, capable of performing a larger variety of exercises. Accordingly, the present invention relates to an exercise apparatus comprising: (a) A basically square base, two supports extending upwardly from base, approximately perpendicular to base and parallel to each other, a handle horizontally connected to supports, and said base unit fixedly mounted upon four swivel type casters.

Patent CA-2444497-A1 (CA)
Inventor: TALAVERA VICTOR C
IPC: B26B19/20
Filed: 2002-04-16
Abstract: A hand held hair trimming device (10) which when pulled through the hair cuts only a determined portion of the ends of hair strands while leaving adjacent hairs uncut. The device will cut a predetermined length off only the distal ends of the hair shafts each time it has the hair drawn through its serpentine channel. Angled encounter of the distal ends with the cutting blade (72) is prevented by ridges and apertures (53) encouraging such contact only at substantially straight angles. The device may be held in either hand allowing the hair pass through in either direction by merely changing the rotational direction of the motor by moving the thumb switch. The blade section of the device may be adjustable for changing the amount of the determined length to be cut from the hair shafts or may be removable and replaceable with one of a plurality of differently configured blade assemblies thereby allowing for adjustment of the trimmed amount.

Title: Modele de racle concu pour mesurer le transfert d'encre vers des cellules anilox
Inventor: HANACHIAN JOEY
IPC: B41F31/20
Filed: 2002-04-23
Abstract: L'invention concerne un dispositif de racle duale, à autorégulation pouvant mesurer avec précision la distribution d'encre au niveau d'un rouleau anilox (3) d'un système d'impression flexographique. Ce système utilise un modèle de lame duale rétractable avec une chambre à encre et un espacement entre la racle inférieure (11) et le rouleau anilox. La racle supérieure (14) de ce système rentre en contact avec le rouleau anilox au niveau d'un certain point, après avoir tourné à travers le plateau d'application, et gratte l'encre de la surface du rouleau d'anilox, pour l'amener directement dans la chambre à encre. A mesure que la chambre se remplit d'encre, la pression hydraulique créée par la rotation dudit rouleau d'anilox augmente jusqu'à un certain point auquel les cellules anilox sont remplies pour atteindre le volume approprié. Cet espacement permet alors la distribution d'un volume adéquat d'encre aux cellules anilox (10), ainsi que l'expulsion de l'encre de la chambre, lorsqu'une pression hydraulique critique est atteinte.

Filed: 2002-06-13
Abstract: A method for providing an early packet termination such that prior to the complete transmission of the number of cells specified in the first cell of a packet, a crossbar connection is released. The act of releasing the connection is triggered on recognition of an End of Packet bit (EOP) set in any cell of the stream. The feature can be enabled, for example, by a specific act of setting a register bit, connecting a pin to Vcc or ground or some other intentional act. The feature will default to the inactive state upon reset.
