Title: Plant containerizing and watering device
Inventor: DION ANDRE
IPC: A01G9/02
Filed: 1999-06-22
Abstract: A plant containerizing and watering device for containing a plant growing medium and facilitating irrigation of the growing medium by a liquid. The device includes a first container and a second container. The second has at least one venting aperture extending through its base wall. The second container is configured and sized so as to be at least partially insertable within the first container with their respective base maintained in a predetermined spaced relationship relative to each other. A trough extends outwardly from the second container. The trough has at least one trough aperture positionned betweeen the first and second container base walls. A removable reservoir is inserted within the second container. The device also includes a valve mechanism, in fluid communication with the removable reservoir for selectively and automatically transfering a transfer volume of liquid from the removable reservoir to a relatively constant volume of liquid contained between the base walls of the first and second containers so that the surface of the relatively constant volume of liquid is maintained at a relatively constant base level allowing fluid communication with the trough aperture. When a fraction of the relatively constant volume of liquid is soaked up through the trough aperture by a capillary action of the growing medium contained in the second container the valve mechanism transfers a corresponding volume of the liquid from the removable reservoir to the volume beween the base walls.

Title: Uninterrupted extension system for atm devices and uninterrupted extension method
Inventor: IWASAKI TAKASHI
IPC: H04L12/931
Filed: 1999-07-08
Abstract: An ATM device comprises a basic module route passing through a basic module 11 and an extension module route bypassing through an extension module 12. The basic module produces a route switch instruction when the basic module route is switched to the extension module route. In response to the production of the route switch instruction, a switch control cell is inserted into all data received.      When the switch control cell is detected in the data on the basic module route, main signal cells on the basic module route are all discarded. When the switch control cell is detected in the data on the extension module route, a selection control signal is produced which indicates switching from the basic module route to the extension module route. In response to the production of the selection control signal, the basic module route is switched to the extension module route.

Patent CA-2284714-A1 (CA)
Inventor: VAN DEN BURG LAMBERTUS
IPC: A23J3/34
Filed: 1998-03-23
Abstract: La présente invention concerne des gènes codant des variants de métallo-endopeptidases qui ont été modifiées génétiquement pour résister à une ébullition prolongée et conservent cependant leurs propriétés enzymatiques à des températures beaucoup plus basses. En outre, la stabilité thermique des métallo-endopeptidases dépend notamment des teneurs en calcium, lesquelles sont de l'ordre du mM. L'invention concerne en outre des variants de métallo-endopeptidases actives, dont la stabilité peut être modifiée en fonction de la teneur en calcium, afin de constituer des métallo-endopeptidases qui sont dépendantes ou non du calcium. L'invention concerne encore des gènes codant des métallo-endopeptidases résistantes à l'ébullition et dont la stabilité, qui dépend de la teneur en calcium, peut être changée, ainsi que des vecteurs et des cellules comprenant ces gènes, et des protéases produites au moyen de ces gènes, vecteurs et/ou cellules. On décrit notamment des variants de protéases de type thermolysine, possédant les propriétés ci-dessus décrites, tels ceux produits par Bacillus stearothermophilus (TLP-ste) et Bacillus thermoproteolyticus (thermolysine). On peut utiliser des métallo-endopeptidases résistantes à l'ébullition et dépendantes ou non du calcium, dans divers procédés industriels, par exemple dans la préparation de l'édulcorant artificiel aspartame, mais également dans l'industrie du cuir, dans des brasseries et dans la production d'hydrolysats de protéines.
Patent CA-2284842-A1 (CA)
Inventor: VERGNES ALAIN
IPC: H03L7/18
Filed: 1999-01-14
Abstract: A direct digital frequency synthesizer featuring a modulo accumulator (17;  117) addressing a multiplexer (33; 133). The multiplexer receives a series of delay signals generated from digital circuits (41-45; 141-153). The delay signals establish the phase of a reference oscillator (37; 137). The number of units of delay are sufficient to resolve expected jitter. The accumulator is a digital counter which increments by only a single digit for each count, such as a Gray code counter. In one embodiment, the delay signals are generated by a charge pump (43; Fig. 5) feeding individual logic circuits (41; Figs. 3-4) driving integrated capacitors in a loop. Feedback to the charge pump establishes that the total delay will subdivide a single clock cycle of the reference clock. In a second embodiment, a single shifter or several shifters (151; 153), with output in phase reversal relation (145), subdivide a single clock cycle. A clock multiplier (141) and divider (147) are used to assure the synchronism of each clock cycle with the total number of units of delay. The output (33; 155) of the multiplexer (33; 133) is the reference oscillator signal, adjusted by the phase delay, forming a synthesized output frequency.

Abstract: An auger compactor is described in which a hopper is provided to feed vegetation into the intake end of a compression chamber which leads from the intake end opening into the hopper to a discharge end. A first helical auger flight extends along an auger axis, of a pitch that diminishes from a maximum pitch adjacent the intake end of the compression chamber to a minimum pitch adjacent the discharge end. A second helical auger flight is also situated within the compression chamber, circumscribing and slidably supporting the first helical auger flight. The second auger flight includes a second helical pitch that also diminishes from a point adjacent the intake end of the compression chamber to a point adjacent the discharge end of the compression chamber. A drive is provided to rotate one of the flights about the auger axis, to move and compact vegetation along a flow path from the hopper through the discharge end of the compression chamber. An over-compression chamber opening into the discharge end of the compression chamber, with a compression bulkhead positioned normal to the auger axis. An over-compression member faces the compression bulkhead across the over-compression chamber and is driven to forcibly shift the over-compression member between a first position spaced from the compression bulkhead by at least a bale width dimension and a second position spaced from the compression bulkhead by a distance less than the bale width dimension.

Title: Method and system for digitizing handwriting
Inventor: KORSENSKY VICTOR
IPC: G06F3/033
Filed: 1998-06-25
Abstract: A system and method for tracking a moving object very accurately at short ranges in general, and a handwriting input device such as a pen (106) in particular. The method is based on measuring times of arrival of ultrashort RF  pulses transmitted (201) by the pen to an array of receivers (100-103).  Dealing with the ultrashort events is done by "strobing" the pen position. To achieve the necessary resolution, on the order of 0.25 mm, the times of arrival of the pulses are determined by sampling the pulses digitally and fitting appropriate mathematical function to the sampled pulses. The time jitter is averaged over many sweeps, and a dedicated receiver is used for synchronization.

Title: Behind the ear hearing aid system
Inventor: BARNARD DAVID
IPC: H04R25/02
Filed: 1998-07-17
Abstract: The hearing aid system includes a hearing aid case which is designed to be positioned behind the ear of a user, a tube for conducting sound from the case to the ear canal of the user, and an eartip for anchoring the end of the tube within the ear canal of the user. The tube is formed in a preformed shape of a material with sufficient rigidity to support the hearing aid in a proper position on the user's ear. The eartip may be one of several different designs which secures an end of the tube in place in the ear canal in a comfortable manner without the need for an expensive custom made ear mold and without complete occlusion of the ear canal. A combination of the light weight and small size of the case, the rigidity of the preformed tube, and one of the eartips for anchoring the tube in the ear canal allow the system to be held in place securely without the need for either an inflexible and aesthetically unpleasing ear hook or an expensive custom made ear mold.
