Patent CA-2280920-A1 (CA)
Inventor: WOODS CARL HENRY
IPC: E04H3/28
Filed: 1998-02-17
Abstract: A collapsible stage (1) is provided which has a first planar wing (3), a second planar wing (5) and an intermediate planar section (7). The respective wings (3 to 5) are hinged to respective sides of the intermediate section (7) so they can both swing upwardly from a plane where they are co-planar with the intermediate section where they collectively form an open stage (1), to a collapsed position where both wings (3 to 5) are generally parallel to one another and extend upright. The intermediate section (7) has ground engaging means (17) to permit rolling or sliding movement of the collapsed stage. A first pair of retractable legs (11) are connected with an underside of the first wing (3) adjacent one side of said intermediate section (7), and a second pair of retractable legs (13) are connected with an underside of the second wing (5) and the other side of said intermediate section (7). These legs (11 and 13) are guided by guide means (21) attached to the intermediate section (7) so that feet means on those legs will be below the ground engaging means (17) when the wings (3 and 5) are swung so they are substantially co-planar with the intermediate section (7), and will be above the ground engaging means (17) when the wings (3 and 5) are swung upwardly to the collapsed position.   The outermost ends of the wings (3 and 5) each have further leg means (35) swingably connected thereto which can be swung from a collapsed position where they extend substantially parallel to the planes of the respective wings (3 and 5) to erect positions where they are substantially perpendicular to the planes of the wings (3 and 5).

Patent CA-2295554-A1 (CA)
Inventor: TAMKIN JOHN M
IPC: G02B26/12
Filed: 1998-06-19
Abstract: On décrit un lecteur laser incluant un relais optique qui reforme une image provenant d'une lentille de balayage à un emplacement pouvant fournir une distance frontale additionnelle. Le relais optique contient des éléments à réflectance prépondérante qui permettent une focalisation achromatique pour le rayonnement ultraviolet. Une forme de réalisation du relais optique présente un grossissement d'environ 1 et met en oeuvre des miroirs sphériques dans une configuration telle que la déformation et les aberrations de l'image sont éliminées. Un deuxième relais optique réduit la grandeur de l'image en utilisant des miroirs asphériques (miroirs paraboliques ou elliptiques, par exemple). Une lentille additionnelle élimine les déformations ou aberrations introduites dans le deuxième relais optique. La distance frontale additionnelle permet d'insérer sur le parcours du relais optique des appareils optiques (séparateurs de faisceaux, par exemple), des prismes de correction des chevrons ou des dispositifs optiques à réglage automatique.

Title: Ask modulator and communication device using the same
Inventor: NAKAO MOTOYASU
IPC: H04L27/04
Filed: 2000-04-28
Abstract: An ASK modulator can be operated with only a positive-voltage power source. A source-voltage switching circuit that applies a positive voltage to the source of an FET when a data signal is at an L level in relation to the source of the FET is connected to the source of the FET which has a negative pinch-off voltage. Since the L level of the data signal can be set to 0 V, the ASK modulator can be configured only with the positive-voltage power source.      This allows miniaturization and cost reduction to be implemented.

Title: Digital signature system
Inventor: PAVLIK PATRICK
IPC: H04L9/32
Filed: 2000-05-25
Abstract: A digital signature system includes a data receiver for receiving an electronic document over a network; an encryption key database, and a signature processor in communication with the encryption key database and the data receiver. The encryption key database includes encryption key records, each being associated with a subscriber of the database and identifying an encryption key uniquely associated with the subscriber. The signature processor is configured for receiving an indicator of one of the subscribers and for deriving a digital signature from the received electronic data and the encryption key associated with the one subscriber. Upon receipt of electronic data and an indicator of one of the database subscribers, the digital signature system derives a digital signature from the received electronic data and the encryption key associated with the one database subscriber. Typically, the database subscriber is the originator of the electronic data, and the data originator identifies itself by providing the signature processor with a personal identification number assigned to the data originator. After the digital signature is derived, preferably the digital signature system then transmits the derived digital signature to the data originator.

Title: Multi-stage filtration and softening module and reduced scaling operation
Inventor: COTE PIERRE
IPC: C02F1/44
Filed: 2000-07-07
Abstract: A filtration module comprising has a plurality of preceding or succeeding stages of hollow fibre membranes. The lumens of the membranes are the retentate or feed side. The lumens of the membranes of the stages are connected in series between a module inlet and retentate outlet. A permeate collection plenum is in direct fluid communication with each stage. The stages are connected by caps typically having dividers located at the ends of the module. The caps and dividers collect the membranes into the stages such that the surface area of the membranes of each preceding stage is between 1 and 2.5 times the surface area of the membranes of a directly succeeding stage and the surface area of the stages decreases from the first stage to the last stage. Liquid, typically water, being filtered flows through the stages in series with interstage flows through the caps and dividers being generally parallel to the periphery of the module. Optionally, the caps and dividers re-collect the membranes into stages such that the same surface area relationship applies when feed flows through the module in a reverse direction. The module is used to filter water and when optionally fitted with hollow fibre membranes adapted to selectively reject hardness causing salts is used to remove hardness. Carbon dioxide or other suitable acids may be added to the feed water to control scaling.
