Patent CA-2386959-A1 (CA)
Inventor: HEPPE BIRGIT
IPC: B01D65/08
Filed: 2000-04-28
Abstract: The invention relates to a method for purifying waste water which combines membrane filtration and electrolysis and in this way permits a high purifying effect with virtually no backwashing. Purification yields a high-quality waste water which is suitable, for example, as process water in household use. The corresponding installation is compact and can be used as a domestic fitting, outdoors or for retrofitting to existing water treatment works. According to the invention the waste water is fed into a container comprising a cathodic membrane and an anode. The waste water passes through the membrane which repels negatively ionized particles which then become deposited on the anode.  By cyclic reversal of anode polarity the particles are repelled again by the anode and settle on the inclined bottom of the container. The sediment is withdrawn via a sludge discharge line. The cathodic membrane is backwashed during reversal of anode polarity.

Patent CA-2396162-A1 (CA)
Inventor: SANDBERG STUART DANIEL
IPC: H04B3/23
Filed: 2001-01-25
Abstract: An echo cancellation device relies on the known characteristics of the sync frame to monitor, update in an off-line fashion and determine the accuracy of an echo canceller in, for example, a modem, such as an ADSL modem.  Specifically, time domain samples are read from the transmit (Tx) and receive (Rx) paths of the modem. These samples are stored in memory. When the sync frame has received a predetermined number of the same Tx samples and Rx samples, the samples are stored. Running averages, over the sync frames, of the TX and Rx samples are maintained. These averages are subtracted from a sync frame of samples, to allow LMS updating of the echo canceller taps, free of extraneous signals. Updating, i.e., tracking of changes in the echo channel, is done for the echo canceller in an off-line fashion. The coefficients for the in-line version are updated, while the off-line version is updated over several sync frames. Periodically, the performance of the off-line version is compared with the in-line version. The coefficients of the in-line version are replaced by those of the off-line version only if it is determined the off-line version, which is tracking echo channel changes, has better performance. After replacement of the in-line coefficients, the off-line tracking is continued in the off-line version.

Title: Stroller with spring-biased brake pins
Inventor: LAN RED
IPC: B62B5/04
Filed: 2002-08-13
Abstract: A stroller includes a frame assembly with a pedal-mounting rod, on which a brake pedal is mounted rotatably. When the brake pedal is turned downward, a coupling mechanism activates two resilient elements to bias two brake pins to project from two pin holes in two mounting seats. At this time, in case the brake pins are aligned with two of a plurality of brake holes in two rear wheels, they are biased into the two brake holes. In case the brake pins are deflected from all of the brake holes, they are biased to press against the surfaces of the rear wheels. Under such conditions, the rear wheels are rotated slowly by pushing the stroller so as to permit the brake pins to be biased into two of the brake holes.

Inventor: GAGNON ROBERT
IPC: B01J37/04
Filed: 2002-11-27
Abstract: Comme la COpétrolisation fait appel à deux catalyseurs au lieu d'un seul, la conversion du CO en C7H16 se fait beaucoup mieux. L'addition du sel au catalyseur de fer améliore grandement le rendement du procédé de Fischer parce que le sel retient l'humidité, que le chlore du sel ouvre l es chaînes et le sodium du sel empêche les cristaux d'oxygène de se former à la surface du catalyseur de fer.   Si on est équipé pour fabriquer du CO, pour capter les biogaz et/ou les fumées d'usines ou, si on dispose involontairement de CO , on peut rendre ce gaz indésirable très utile à l'économie par la COpétrolisation. En effet, recycler le CO en pétrole synthétique contribue à nettoyer l'atmosphère tout en procurant une source d'énergie non-négligeable.   Comme le CO est une ressource renouvelable, la COpétrolisation favorise aussi le développement durable.

Abstract: A method and system are provided for acoustic noise removal from human speech, wherein noise is removed without respect to noise type, amplitude, or orientation. The system includes microphones and a voice activity detection (VAD) data stream coupled among a processor. The microphones receive acoustic signals and the VAD produces a signal including a binary one when speech (voiced and unvoiced) is occurring and a binary zero in the absence of speech.  The processor includes denoising algorithms that generate transfer functions.  The transfer functions include a transfer function generated in response to a determination that voicing information is absent from the received acoustic signal during a specified time period. The transfer functions also include transfer functions generated in response to a determination that voicing information is present in the acoustic signal during a specified time period.  At least one denoised acoustic data stream is generated using the transfer functions.

Abstract: The invention includes a process and components for making stamping dies from a set of mass produced metal blocks, each machined to size, each with dowel, counter bored and tapped holes machined along an Upper and Lower Machining Line.  Blocks are of same thickness and width. Each successive block of a set increases in length by a fixed or variable distance. Individual blocks can be mounted directly onto the die-set. Blocks can also be assembled together. Machining pattern of holes in each block is such that when dowel holes align, counter bores of one block align with tapped holes of joining block. All blocks are ready for final custom machining. A set of blocks is designed to accommodate strip widths within a given range. The result is a reduction in die-making time and cost.
