Patent CA-2241741-A1 (CA)
Inventor: MATSUO MAMORU
IPC: F23G7/06
Filed: 1996-12-27
Abstract: A deodorizing furnace directed to making an equipment compact and considerably enhancing a thermal efficiency of the furnace as compared with the prior art. An out-of-furnace circulation circuit (4) connects a deodorizing furance (1) to a thermal equipment (8), which makes use of intermediate and low temperature air currents as a heat source, so as to circulate a combustion exhaust gas in an interior (2) of the deodorizing furnace, which has been used for incineration or thermal decomposition of odor components. When the combustion exhaust gas passes through heat accumulating bodies (5A or 5B) on a suction side of the out-of-furnace circulation circuit, a part of its sensible heat is recovered by the heat accumulating bodies (5A or 5B) and is fed to the thermal equipment (8) as intermediate- and low-temperature air currents which are usable in the thermal equipment (8). After completing a predetermined work in the equipment (8), the air currents make use of recovered heat at the heat accumulating bodies (5A or 5B) on a discharge side of the out-of-furnace circulation circuit to be made high in temperature to be returned to the interior (2) of the deodorizing furnace. Accordingly, a part of heat generated in the interior (2) of the deodorizing furnace and not fully recovered by the heat accumulating bodies (5A or 5B) and discarded, is used as a heat source of the thermal equipment (8), and it is possible to make the equipment compact and low in cost without the need of any additional air-heating furnace for the thermal equipment (8).

Title: Secure metering vault having led output for recovery of postal funds
Inventor: LEE DAVID K
IPC: G07B17/00
Filed: 1998-07-15
Abstract: A secure metering vault for use with a host printing module via a secure communication link includes a secure output device such as a light emitting diode (LED) configured for outputting the available postal funds stored in the secure metering module in response to a detected malfunction in the secure communication link. The vault includes a processor that monitors the condition of the secure communication link, and that controls the storage and updating of the stored available postal funds in a nonvolatile memory. If a failure is detected in the communication link, the processor outputs to the LED the stored value of the available postal funds based upon a prescribed format, such as Morse code or some other blinking pattern that is equivalent to the postal funds remaining in the vault. Use of the secure output device to output the stored available postal funds enables a user to recover the funds without tampering with the secure metering module, which may otherwise cause self-destruction of the vault or deletion of the available postal funds from memory.
Patent CA-2244047-A1 (CA)
Inventor: HERMANSON DAVID WILLIAM
IPC: G06T15/70
Filed: 1998-07-28
Abstract: Image data representing image frames are edited. Segment data is storedand image frames are displayed in response to this segment data. A visual display displays visual elements representing adjoining image segments in response to the segment data. A manual input device selects and adjusts transitions between adjoining segments so that the segment data is modifiable in response to these adjustments. The system is configured to selectively operate in a linked mode or in an unlinked mode. In the linked mode, movement of a transition between adjoining segments maintains the segments as being adjoining by adjusting the lengths of both of the segments. In the alternative unlinked mode, movement of a transition results in the length of one of the segments being modified while its adjoining segment retains its original segment length.

Abstract: Improved techniques for synchronizing transmissions and receptions of a data transmission system utilizing time division duplexing is disclosed. The improved synchronization techniques utilize the time-varying nature of the energy of the received data to obtain synchronization. In one embodiment, an improved synchronization processing (500) measures energy (502) in n consecutive frames of received data. An alignment error estimate is then computed (504) based on the measured energy values for the n consecutive frames. In another embodiment, the improved synchronization technique uses the output signals from a multicarrier modulation unit (FFT unit) and thus provides the ability to avoid frequency tones that are susceptible to RF interference. The improved synchronization techniques can also utilize crosstalk interference levels to obtain synchronization. Remote receivers in the data transmission system are able to synchronize to central transmitters, central receivers in the data transmission system are able to synchronize to remote transmitters, and central transmitters are able to synchronize with one another.

Patent CA-2258031-A1 (CA)
Inventor: SHERWOOD WILLIAM LYON
IPC: B21B31/20
Filed: 1996-06-10
Abstract: La présente invention concerne des améliorations apportées à des cages de laminoir d'ébauche, de traitement intermédiaire et de finition à cylindres montés en porte-à-faux, applicables essentiellement au laminage à chaud des produits longs. Une amélioration fondamentale apportée aux cages de laminoirs duo et sexto consiste à monter les paliers à roulement (20) sur un arbre en porte-à-faux fixe (12), directement sous l'anneau de laminage (21), éliminant ainsi les paliers d'appui principaux à forte charge qui sont confinés dans un espace radial limité lorsqu'ils sont montés à l'intérieur du logement de la cage. Des ensembles moteurs d'entraînement individuels pour chaque arbre, couplés de façon rigide et directement supportés par les arbres d'entraînement (28), constituent une caractéristique préférée, plutôt que des dispositifs d'entraînement fixés sur plancher et agissant par l'intermédiaire de cages à pignons sur des broches et des accouplements. Ceci permet d'éliminer les forces de réaction à l'entraînement qui agissent contre l'ensemble cage, de mesurer et régler directement la traction/compression entre les cages à l'aide de barres de charge placées entre les cages, et de faciliter les applications de ladite invention aux trains de laminoirs en tandem dans lesquels le laminage se fait directement, automatiquement, en continu et sans tension. Un ensemble laminoir sexto présente des ensembles cartouches pour cylindres de travail pouvant être installés hors ligne afin de permettre des changements très rapides de cylindres et de guides, ce qui peut être particulièrement utile pour les applications aux passes intermédiaire et de finissage. Les cylindres de travail (64, 130) sont dépourvus de tourillons, le cadre (58) de la cartouche et les paliers (65) ne servant qu'à maintenir la position des cylindres plutôt qu'à porter les charges de laminage. La taille et le matériau des cylindres peuvent dès lors être choisis en fonction des formats courants et d'exigences de réduction de taille plutôt qu'en fonction de leur capacité de charge. Des moyens permettent de régler axialement la position des cylindres et de séparer les cylindres de manière symétrique de part et d'autre de la ligne de laminage. Les châssis des cages de laminoirs présentent la caractéristique supplémentaire d'une orientation transversale horizontale, verticale ou angulaire, ladite orientation pouvant être modifiée rapidement.

Patent CA-2272991-A1 (CA)
Inventor: HASTY PAUL
IPC: A61K38/00
Filed: 1997-11-05
Abstract: When a mutation, designated rad51M1, was generated in the mouse MmRAD51 gene, mutant embryos died shortly after implantation. rad51M1 cells exhibited hypersensitivity to ionizing radiation, reduced proliferation, programmed cell death and chromosome loss. The disruption of MmRad51 protein-protein interactions stopped cell proliferation and/or reduced cell viability. Several proteins that interact with MmRad51 have been identified including, for example Brca2 and M96. Additionally, Rad51 self-associates via the N-terminal region. When a single residue was changed from a conserved lysine to an alanine, the alteration proved toxic to cells. Moreover, a rad51 allele that lacked the RecA homology region was also deleterious to cells. In view of the above, it is clear that inhibiting MmRad51 function or the function of any molecule that associates with MmRad51, or any molecule in the Rad51 or Rad52 pathways, hinders cell proliferation and/or viability. Accordingly, molecules capable of blocking these critical DNA repair pathways may be effective as therapeutics for inhibiting cell proliferation.
