Patent CA-2020803-A1 (CA)
Title: Process and apparatus for collecting and stapling folded printed sheets
Inventor: HANSCH EGON
IPC: B27F7/21
Filed: 1990-07-10
Abstract: A process and apparatus for collecting and stapling printed products is provided.  A self-enclosed track of travel for stapling heads extends around a collector drum having a plurality of supports.  A stapling head is assigned to each support.  The stapling heads rotate mutually synchronously about the axis of rotation of the drum.  While running past a wire section dispenser, each stapling head accepts a wire section from which a staple is formed in a predetermined first region.  In a second region, the staple is brought onto the side of the stapling heads facing the supports.  In a third region, the stapling heads are lowered onto the printed sheets, which are deposited onto the supports, and stapled together.

Patent CA-2023821-A1 (CA)
Inventor: VANDER MEY JAMES E
IPC: H04L7/06
Filed: 1990-08-22
Abstract: Spread spectrum chirps (i.e., wideband frequency packets) are propagated on a local area network in a hostile communications environment, such as a powerline or a crowded radio frequency band. chirps are self-synchronizing, data bit (or subdata bit) in length and detectable by all network nodes, to allow the contention resolution and collision detection needed to support carrier-sense based network protocols. A matched filter of the same time length and encoding sequence as the transmitted chirp provides the self-synchronized chirp reception at each receiver.

Patent CA-2034052-A1 (CA)
Inventor: BIRDSONG THOMAS E
IPC: B01D61/10
Filed: 1991-01-11
Abstract: A reverse osmosis system includes a sediment filter which cleans feed water from a source and from which that feed water is fed to a reverse osmosis membrane filter. Permeate from the latter is fed to a bladder within a storage tank. Concentrate from the membrane filter is fed to and used within the storage tank as squeeze water for the bladder. When a faucet that delivers permeate to the user is open, squeeze water is used to cause permeate to flow out of the storage tank through an impurity filter to supply the faucet. A valve unit is included to control the amount of squeeze water fed to the storage tank and to regulate permeate flow so that the water outletted from the faucet remains at a constant pressure and provides relief as against overpressure in the system. A proportioning valve within the valve unit serves to maintain at all times a constant ratio of concentrate to permeate flow through the membrane filter for adequate cleansing of the membrane. Also included are input-side and output-side flow monitors which provide signals to a processor that serves to indicate the status of filter conditions. There also is an advantageous faucet assembly for controlling the delivery of permeate to the user with flexibility and convenience.

Title: Locking device
Inventor: SAKAI TADASHI
IPC: E05B65/52
Filed: 1991-03-07
Abstract: LOCKING DEVICE          ABSTRACT OF THE DISCLOSURE     In   the  improvement  to  a  locking  device  of   this invention, a slider is mounted for sliding by a card key with tumblers  being pushed in the sliding direction by  the  card key.  In  addition, since the tumblers are  pushed  into  the slider,  the  slider  does  not prevent  the  card  key  from sliding. Consequently, unlocking or locking operations can be attained  by  sliding  the card key along  the  tips  of  the tumblers without stopping of the card key by a step  portion.          Therefore,  the  improvement  to  a  locking  device  of  the invention  effects  smoother unlocking or  locking  operation than a conventional locking device.

Abstract: JBF144  The invention concerns a sheet folding device for a package producing folding and gluing machine. A sheet (1) is carried forward by a conveyor belt (4) in a direction parallel to a folding  line (O1)  predetermined  by  a  crease.  A  second belt (6) having adopted a helical shape under the action of truncated rollers (7) exerts pressure onto the part or flap  (1') to be folded under the action of the truncated rollers  (7),  and folds the  said flap  over in the  direction of the remainder of the sheet (1). For varying the helical shape of the belt (6), the truncated rollers (7) with different angles are fitted for  appropriate  adjustment on the supports  (7a, 20,  15,  30a)   which  are  pivotable  around  the folding  line  (O1).

Abstract: ABSTRACT            Applicator coil for an electromagnetic therapy apparatus, with an approximately oval-shaped cross-section with a large and a small diameter and can serve to treat the trunk of the human body with low frequency magnetic alternating fields. The cross-section of the applicator coil is asymmetrical relative to the large diameter, in particular the upper part is more strongly curved than the lower part. An applicator coil so formed is felt to be substantially more comfortable by the treated patients than the known applicator coils with a symmetrical, circular or elliptically formed cross-section.
Patent CA-2043111-A1 (CA)
Inventor: NAKAZAWA KENZO
IPC: H01M8/04
Filed: 1991-05-23
Abstract: ABSTRACT OF THE DISCLOSURE     An LNG cryogenic   power generation system using a molten carbonate fuel cell is equipped with   a COz separator.          The CO2 separator takes advantages of cryogenic LNG in a manner such that CO2 among gases discharged from an anode chamber of the fuel cell is liquefied with cryogenic LNG and separated from the anode exhaust gas.    Cell reactions take place at a cathode chamber and the anode chamber of the fuel cell to cause power generation  as the oxidizing gas which contains CO2 is fed to the cathode chamber and the fuel gas is fed to the anode chamber.          LNG is reformed by a reformer of the fuel cell and the reformed gas is fed to the anode chamber.   During the cell reaction, CO2 of the oxidizing gas fed to the cathode chamber is transferred as carbonate ion to the anode chamber and CO2 is enriched or concen-trated before expelled from the anode chamber.    This anode gas is introduced to the CO2 separator.   In the CO2 separator,  CO2 among the anode gas is liquefied by cryogenic LNG and separated from the anode gas.   As a result, the power generation and the CO2 recovery are carried out at the same time, and an amount of CO2 discharged to atmosphere is remarkably reduced.

Title: Circuits logiques rapides a transistors a effet de champ complementaires
Inventor: VINAL ALBERT W
IPC: H03K19/0948
Filed: 1990-04-10
Abstract: Circuit logique FET entièrement parallèle, très rapide, de densité élevée, à faible consommation d'énergie et comportant un étage d'attaque muni d'un certain nombre de FET parallèles d'un premier type de conductivité pour recevoir des signaux logiques d'entrée et un FET de charge appartenant à un deuxième type de conductivité qui est relié à la sortie commune de l'étage d'attaque.  Un inverseur FET complémentaire constitué de FET reliés en série et faisant partie du premier et du deuxième types de conductivité est rattaché à la sortie commune et au FET de charge.  Avec cette invention, la fonction de transfert de tension de l'inverseur complémentaire est désaxée pour que le produit de la mobilité du porteur de charge avec le rapport de la largeur de canal sur la longueur de l'inverseur FET du premier type de conductivité soit sensiblement plus important que le produit de la mobilité du porteur de charge avec le rapport de la largeur de canal sur la longueur de l'inverseur FET du deuxième type de conductivité.  En désaxant la fonction de transfert de tension de l'inverseur complémentaire, on fait décroître considérablement l'intervalle de levée de tension et l'on améliore ainsi la vitesse.  Cette invention permet également d'obtenir des circuits logiques ET et OU et des circuits combinés ET-OU comportant des sorties vraie et complémentaire.  Un transistor à charge en série multiporte permet également de réduire la consommation d'énergie.
