Patent CA-2264327-A1 (CA)
Inventor: RAMBO TAN
IPC: F16G11/10
Filed: 1999-03-02
Abstract: The invention relates to a device used to restrain relative movement of a cord such as a garment drawstring. The one-piece device comprises two resilient arms extending from a base, forming a "V" wedge shape. One or more conduits are spaced transversely along the ends of each arm, having bores sized to pass the cord. When squeezed between with one's thumb and fingers, the spaced conduits of one arm alternate and interlock with the conduits of the other arm with their bores aligned so that the cord can pass continuously therethrough.  When released, the resilient arms of the device try again to spring open and out-of-alignment, distorting the cord for restraining its location relative to the device.    Ease of actuation and its low "V" profile allows the device to be installed protectively within a garment. In another aspect, the device is not necessarily resilient but is instead actuated using a parallelogram double-pinned hinge formed with two additional bars connected between the arms, forming an inside hinge while the base forms an outside hinge. A tether actuates the inside hinge to force the arms between an open and a closed position. Accordingly, great force can be applied to the tether for holding a cord more tightly.

On recueille les mots existant dans l'identificateur d'unité définie et on produit un schéma du programme de traitement dans lequel toutes les palettes nécessaires au logiciel sont disposées dans l'organigramme, en fonction de l'identificateur d'unité définie. On détermine ensuite un fichier nécessaire en fonction des mots recueillis et du schéma du programme de traitement produit. On produit ensuite les premières logiques de base pour l'exécution de l'édition d'image ou de l'édition de fichier, des secondes logiques de base pour la détermination d'un programme de traitement et des troisièmes logiques de base pour la mise à jour du fichier pour tous les mots recueillis. On produit ensuite les trois types de palettes reliant les premières, secondes et troisièmes logiques de base pour toutes les fonctions-images et palettes qui exécutent les logiques de base dans les palettes respectives de manière autonome et avec pertinence. On transmet une image basée sur la fonction palette concernant les premières logiques de base, l'image est reçue, et la fonction palette concernant les secondes logiques de base est exécutée. Ce processus est un itinéraire de traitement parmi d'autres. Les fonctions de palette susmentionnées sont intégrées à une fonction chaîne de palettes qui présente une structure permettant de déterminer un programme de traitement parmi plusieurs, dont le programme de traitement dans lequel la fonction palette concernant les troisièmes logiques est exécutée en fonction des résultats de l'exécution de la fonction palette concernant les secondes logiques.

Title: Surface treated additive for portland cement concrete
Inventor: MCKENNY COLIN J
IPC: C04B24/10
Filed: 1997-12-09
Abstract: The invention is directed at an additive for incorporation into a cementitious compound comprising Portland cement and water prior to the setting of the compound. The additive is comprised of a surface treated additive wherein the surfaces of the additive are treated with a substance which has a transient hydrophobic effect on the additive, which effect temporarily renders the additive more hydrophobic for a time period following the incorporation of the additive into the compound such that the water comprising the compound is less attracted to the additive during the placement of the compound and is thus available to provide workability to the compound, and such that the additive regains its natural properties following placement of the compound in order to permit the additive to participate with the compound during the curing of the compound. The invention is also directed at a process for preparing the additive and a process for preparing a cementitious compound comprised of the additive.

Abstract: An ink ribbon assembly for use in a thermal transfer printer includes a plurality of ink ribbons 17a, 17b and 17c. At least one ink ribbon 17c less influencing the printing accuracy is shorter in length than the other ink ribbons 17a and 17b. The shorter ink ribbon has a terminal end mark 60 formed at its terminal end. At the time point when the end of the shorter ink ribbon is detected in the middle of the printing of one printing area, the other ink ribbons have finished the printing of such printing area, because they are longer than the ink ribbon 17c, and thus, joints cannot be produced in the printing with the longer ink ribbons.

IPC: A61F9/02
Filed: 1999-11-23
Abstract: Eyewear comprising a frame having top, bottom and opposite sides defining a lens opening, each opposite side having lens engaging means, and a lens adapted to be removably attached to the frame to substantially cover the lens opening. The lens posseses translucent front and rear faces, opposite first and second side ends, and a first and second lens locking portions. The first lens locking portion is located at the first side end for cooperatingly engaging one of the lens engaging means at a first opposite side of the frame. The second lens locking portion is located at the second side end for cooperatingly engaging the lens engaging means at a second opposite side of the frame for locking the lens to the frame. The lens is flexible in a direction enabling distance variation between the first and second lens locking portions. Manual pressure exerted on the lens to flex it engages and disengages the locking portions with and from the lens engaging means. The invention is useful in many sports, where there is a need for wearing protective eyewear in order to avoid eye injuries. It is especially advantageous in sports where it is desirable to have the capability to replace eyewear lenses quickly. This may be necessary because of changing light conditions or simply because a lens may be damaged or dirty thereby impeding the wearer's vision.

Title: Methods and apparatus for retrieving messages
Inventor: LONG JAMES R
IPC: H04M3/533
Filed: 1999-12-06
Abstract: Systems and methods of retrieving one or more stored messages from a common message server onto a portable medium selectively attached to a terminal located remote from the common message server. Voice, text, facsimile and/or data messages may be transmitted to and stored on the common message server. The remote terminal reads information from the portable medium, which includes an address of the common message server and an account identifier. Subsequent to reading the information, the remote terminal contacts the common message server and logs on. Subsequent to the remote terminal logging on, the message server forwards any messages stored therein to the remote terminal. The remote terminal receives the messages and stores them on the portable medium. The remote terminal then disconnects from the common message server. The systems and methods could include a feature which assists a subscriber in making a determination not to retrieve messages before connection costs are incurred.      This feature could be provided by an acknowledgment tone provided by the message server or a lack of an acknowledgment tone prior to the message server connecting the call.

Title: Dual band antenna for mobile communications
Inventor: GOUDELEV ALEXANDRE
IPC: H01Q5/10
Filed: 1997-12-26
Abstract: A dual band antenna for mobile communications includes a rod-shaped radiating element having a first portion of a predetermined length connected to a coaxial feed line, and a second portion of a specified length integrally extended from the first portion. The coaxial feed line connects to a ground plate, and a first capacitive load connects to the first portion of the radiating element. A choke surrounds the second portion of the radiating element, and has a shorting end connected to a distal end of the second portion and an open end at a proximal end of the second portion. A second capacitive load connects to the shorting end of the choke. In a higher operating band of the dual band, the input impedance of the choke is high, such that only the first (lower) portion of the radiating element radiates. At a lower operating band of the dual band, the choke's input impedance is lower to allow for radiation from the entire length of the antenna.
