Patent CA-2096034-C (CA)
Title: Horizontal well gravity drainage combustion process for oil recovery
Inventor: KISMAN KENNETH EDWIN
IPC: E21B43/247
Filed: 1993-05-07
Granted: 1996-07-02
Abstract: An in-situ combustion method is provided for the recovery of viscous oil from an oil-bearing reservoir. A linear array of vertical air injection wells is drilled into the reservoir; the wells are completed in the upper portion of the reservoir. One or more gas production wells are provided, remote from the row of injection wells, said gas production wells also being completed in the upper portion of the reservoir. A horizontal oil production well is completed in the bottom portion of the reservoir, aligned with and positioned in spaced relation beneath the vertical injection wells. The reservoir is prepared for ignition and combustion is initiated at each of the injection wells. A hot fluid-transmissive chamber is formed around each of the injection wells as combustion proceeds. Combustion gas communication is established with the gas production wells. Heated oil and water, produced by the combustion front in each hot chamber, drains under the effect of gravity and is produced from the horizontal production well. The main features of the process are the implementation of gravity drainage to a basal horizontal well in a combustion process and the splitting of liquid and gas production.

Title: Bradykinin antagonist peptides
Inventor: KYLE DONALD J
IPC: A61K38/17
Filed: 1992-04-16
Granted: 2000-10-10
Abstract: Novel compounds according to aspects of this invention are provided by the modification of the sequence of the mammalian peptide hormone bradykinin (Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg) by the substitution of the L-Pro at position 7 in a unique manner which produces sequence-related analogues, i.e., hydroxyproline ethers or thioethers, that act as specific and competitive inhibitors of the biological activities of bradykinin to convert bradykinin agonists into bradykinin antagonists. Pharmaceutically-acceptable salts thereof, and compositions containing them are also provided. These compounds are useful in the treatment of various diseases including inflammatory disorders, asthma, septic shock and burn pain, for example, where an excess of bradykinin or related kinins are produced or injected, e.g., by insect bites.

Abstract: WET PRESS FOR A PAPER MAKING MACHINE            ABSTRACT OF THE DISCLOSURE          A wet press for a paper making machine presses out water from a moist paper web.  The wet press has a plurality of press rolls, preferably five.  The press rolls are paired so that each pair defines a respective press nip.  There are preferably at least four press nips defined by the paired press rolls.  The press rolls are so placed and the press nips are so defined and the web is so trained on the path through the wet press that the paper web is always supported by the outer surface of one of the press rolls on the web path from the first press nip to the last press nip.  At the second press nip in the path of the web, each of the press rolls there forms a felt free second press nip and each of the press rolls at the second nip has a closed outer surface.  The same may be true for the fourth press nip.  Some of the press rolls may be shoe press rolls.

Granted: 1999-11-30
Abstract: L'invention se rapporte à une installation pour la décoration de boîtes en fer-blanc cylindriques à mouvement continu, qui comporte des mandrins (20) destinés à recevoir les boîtes non décorées (16), ainsi qu'un transporteur à chaîne (30) destiné à acheminer les boîtes décorées dans un four de cuisson. Les mandrins sont montés sur la périphérie d'un porte-mandrins continuellement en rotation (18). La vitesse du transporteur à chaîne est considérablement inférieure à la vitesse linéaire des mandrins et l'espacement des ergots (29a, 29b) sur le transporteur à chaîne est considérablement inférieur à l'espacement des mandrins. Entre le transporteur à chaîne (30) et le porte-mandrins (18) est placé un tambour de transfert en rotation continue (27) sur lequel sont fixées plusieurs ventouses (36). La vitesse linéaire des ventouses (36) au moment de leur déplacement à travers la région de transfert dépasse la vitesse du transporteur à chaîne et l'espacement des ventouses dans cette région est surpérieur à l'espacement des ergots. Au fur et à mesure qu'elles atteignent la région de préhénsion, les ventouses (36) se disposent en deux rangées, s'éloignent entre elles et se déplacent à une vitesse telle qu'elles suivent essentiellement le mouvement des ergots (29a, 29b) tandis que ces derniers sont chargés les uns après les autres avec les boîtes décorées.

Granted: 2005-09-06
Abstract: A telephone answering device (TAD) (25) which includes a means of intelligently organizing voice messages, associated entered codes such as personal IDs and home telephone numbers, and information stored in the memory of the TAD. These codes or numbers are decoded by means of the caller entering DTMF signals into the telephone which are recognized, recorded and processed by the TAD. When processed with codes and personal information previously entered into the device's memory, the TAD displays (32) the identity of the callers for each message, thus providing a menu of choices, i.e., a list of callers. This enables the user to access messages in a selective manner based on the identity of the caller. The need to listen to the actual voice messages to determine the caller's identity and the need to listen to the messages sequentially or chronologically is obviated, saving both time and effort.

IPC: G09G5/14
Filed: 1994-10-25
Granted: 1999-09-07
Abstract: A method and apparatus for controlling the execution of image processing operations carried out on an array of image signals, the specific operations having been identified by a plurality of predefined windows.      The windows are divided into a plurality of regions, the boundaries of which correspond to transitions from one window region to another. Each region defines an exclusive region within the array of image signals, and the image processing operations to be applied to the signals within the boundaries of that region. The image processing operations are selected by decoding an effect data word that is assigned to each pixel and which follows the pixel along the image processing path. The bits within the effect data word are not assigned individual significance which allows the effect data word, in most cases, to maintain the same bit length even though additional image processing procedures or modules have been added to the image processing path. The apparatus is designed to efficiently manage the identification of regions while minimizing the bit length of the effect data word used to identify the image processing steps.    The apparatus also provides flexibility of architecture design resulting in more efficient expansion of functions and easier modifications to existing functions.
