Patent CA-2232049-A1 (CA)
Title: Compact anamorphic motion picture system
Inventor: VETTER RICHARD
IPC: G03B1/48
Filed: 1996-07-26
Abstract: A method is described for producing Cinemascope-type motion picture images that have a large aspect ratio (e.g. 2.35 to 1), which enables their high quality projection using moderately priced projection lenses, which produces a steadier projected image, and which increases the life of the release print while reducing its cost. A scene is photographed in the prior art manner, using an anamorphic lens to produce 50 % horizontally compressed anamorphic camera film frame images (aspect ratio of about 1.175 to 1). During processing to produce a release print, another anamorphic lens is used to produce 36.5 % vertically compressed anamorphic release print film frame images (aspect ratio of 1.85 to 1) of the camera film images. An anamorphic projection lens is used in a motion picture theater to horizontally expand the projected images by about 27 % (to an aspect ratio of 2.35 to 1). The fact that the anamorphic projector lens horizontally expands the image by only 27 % instead of the 100 % of the prior art, enables the projection of extremely sharp and undistorted images on a screen, using a moderately priced anamorphic lens. The fact that the release print images have been vertically compressed, results in their convenient use in current projectors, in the use of less film for each release print, in a longer lifetime of use for each release print, and in a steadier image. Each release print film frame occupies 2.5 perforations instead of 4, which results in a steadier projected image.

Title: Differential total-gas determination while drilling
Inventor: ZAMFES KOSTA
IPC: E21B49/00
Filed: 1998-04-30
Abstract: Apparatus and process is provided for establishing values of the quality of gaseous hydrocarbons in gas extracted from mud while drilling. Two rare earth sensors, without a coating, are exposed to the extracted gas. The first sensor is pre-calibrated and outputs a signal proportional to the relative concentration of light hydrocarbons. The second sensor is pre-calibrated and outputs a signal proportional to the relative concentration of heavy hydrocarbons. Preferably a second sensor is selected which, during calibration outputs a signal which is also proportional to the relative concentration of light hydrocarbons in a light sample gas and outputs a signal which is inversely proportional to the relative concentration of heavy hydrocarbons in a heavy sample gas. The difference of the two signals is obtained and is compared to the first sensor signal as being indicative of the quality of any hydrocarbons present in the extracted gases.

Title: Hydrogen production apparatus and method operable without an external supply of steam and suitable for fuel cell systems
Inventor: MATSUBAYASHI TAKAAKI
IPC: H01M8/06
Filed: 1998-05-22
Abstract: A hydrogen production apparatus is disclosed which operates based on a steam reforming method and operates without supply of steam from outside. The hydrogen production apparatus humidifies air by allowing air to contact with warm water to generate a mixture of air and steam, mixes the mixture with a hydrocarbon fuel. Alternatively, the hydrogen production apparatus humidifies a mixture of a hydrocarbon fuel and air by allowing the mixture to contact with warm water to generate a mixed gas of the hydrocarbon fuel, air, and steam. The hydrogen production apparatus then allows air to partially oxidize the hydrocarbon fuel and allows the steam to reform the hydrocarbon fuel, resulting in the production of hydrogen.

Patent CA-2246509-A1 (CA)
Inventor: MORIWAKI HISAYOSHI
IPC: H04N19/625
Filed: 1998-09-04
Abstract: When a spectrally spread additional information signal, obtained by spectrum spreading additional information such as an anti-duplication control signal or copyright information, is superimposed on a video signal, the level of the spectrally spread additional information signal is controlled according to the scatter of pixel values in each block comprising plural pixels.  The sensitivity of detecting additional information from the spectrally spread additional information signal is therefore improved, and the visual effect of the spectrally spread additional information signal on a reproduced image is suppressed.

Title: Systemes de messagerie
Inventor: STOCKTON TOBY JAMES
IPC: H04L12/58
Filed: 1997-02-26
Abstract: La présente invention concerne un système qui est commandé par une fonction de commutation des services (22), ou "SSF", et par une fonction de régulation des services (23), ou "SCF", qui peuvent se trouver en différents emplacements du réseau afin que n'importe quel client puisse utiliser n'importe quelle plate-forme de messagerie (27, 28) pour le stockage de messages et qu'il soit possible d'utiliser les protocoles de messagerie habituels. Dès la détection d'une requête de service de messagerie, la SSF (22) alerte la SCF (23) via les chemins de signalisation du réseau en transitant par le central numérique local (16) et les unités principales de commutation numériques (17), ou "DMSU". La SCF prend en charge la communication du client, et, utilisant des données conservées dans une mémoire de données de services (24) ou "SDF", réalise les messages d'interrogation appropriés, les contrôles d'accès voulus et remplit les fonctions de stockage. Le stockage des messages se fait en mode distribué, c'est-à-dire qu'une séquence de messages pour un même client ne seront pas systématiquement conservés au niveau de la même plate-forme de messagerie, la SDF (24) ne connaissant que l'emplacement de chacun des messages conservés. Tous les messages FAX, de messagerie vocale, de messagerie de données et de messagerie électronique peuvent être stockés de la même manière.

Patent CA-2252241-A1 (CA)
Inventor: HARDY FRED
IPC: H03J7/04
Filed: 1998-10-29
Abstract: Fast recovery is provided from transient loss of a received carrier in a satellite or terrestrial modem.  A carrier tracking loop, loop filter and steering loop are provided in the modem.  The occurrence of a transient condition affecting the carrier tracking loop is detected.          The loop filter is flushed in response to the transient detection for a time period dependent upon an anticipated length of the transient condition. A voltage of the loop filter is steered toward a predetermined pre-transient value during the flushing step to minimize any change in frequency of the carrier tracking loop when the loop filter is flushed. After the filter has been flushed, the carrier tracking loop attempts to quickly reacquire the carrier.

Patent CA-2260678-A1 (CA)
Inventor: MILLER VAN
IPC: A23D7/02
Filed: 1999-02-04
Abstract: A reduced-fat table spread which is spreadable at refrigeration temperature, and up to 20°C to 25°C, has the appearance, flavour, consistency, rheology, and mouth-feel, which is similar to that of butter or margarine. However, the reduced-fat table spread includes a significant portion of non-fat milk solids, together with water, and vegetable oil. A further colloid carrier may also be included in the formulation of the reduced-fat table spread, together with other optional trace elements, including salt, potassium sorbate, sodium benzoate, citric acid, lecithin, butter flavour ingredient, butter culture ingredient, and colour ingredient. The table spread is soft, but has a solid appearance, and is spreadable at refrigeration temperature and up to room temperature. These factors are achieved as a consequence of protein coagulation at elevated temperatures of a stirred mixture of the starting materials; whereby the water content of the table spread is bound by the protein constituents thereof in a continuous phase dispersion. The vegetable oil content, on the other hand, is present in a discontinuous phase, suspended in the continuous phase dispersion.      During production of the reduced-fat table spread, the product is not homogenized until after protein coagulation at elevated temperatures has taken place.
