Title: Laser monomode utilisable dans des applications a multiplication de frequence et methode connexe
Inventor: XIE PING
IPC: H01S3/109
Filed: 1998-05-26
Granted: 2002-01-22
Abstract: L'invention concerne une configuration de laser monomode et un procédé associé. Le laser (10) peut recevoir un dispositif de multiplication de fréquence qui le transforme en laser à intracavité à doublage de fréquence unique. La configuration de laser comprend un miroir d'entrée (20) et un miroir de sortie (22) définissant une cavité résonnante et un trajet lumineux dans ladite cavité et entre les miroirs. Un matériau à effet laser (24) est placé sur le trajet lumineux pour donner l'effet laser, à la longueur d'onde fondamentale voulue et éventuellement à d'autres longueurs d'onde non voulues. Un premier élément biréfringent (26) est également placé sur le trajet lumineux pour assurer la réfraction dans différentes directions des longueurs d'onde de la lumière sur le trajet. On place aussi dans ledit trajet un second élément biréfringent (28) qui coopère avec le premier élément biréfringent de sorte que ces deux éléments fassent ensemble la distinction entre la longueur d'onde fondamentale voulue et les longueurs d'onde non voulues, de sorte que soit assurée la réfraction d'une polarisation de la longueur d'onde fondamentale voulue dans une direction, ce qui induit un effet laser, alors que la réfraction de certaines parties des longueurs d'onde non voulues est assurée dans d'autres directions, ce qui supprime toute polarisation des longueurs d'onde non voulues.

Abstract: A food container and its method of use are disclosed. The food container includes a top panel, bottom panel and plurality of sidewalls. A movable panel is hingedly connected to one of the sidewalls, allowing a consumer to open the container. Attached to the lower edge of the movable panel is a shelf supporting a food item. A consumer can access the food item by opening the movable panel, which causes the shelf to carry the food item outside the container into a position that permits the consumer to easily manipulate it. The food item or a portion thereof can then be replaced in the container by simply closing the movable panel. The shelf may engage one or more sidewalls of the bottom panel to assist in maintaining the container in a closed position after initial opening and reclosing.

Title: Method for acquiring an alternate communication system
Inventor: SORENSON JOHN R
IPC: H04B17/00
Filed: 1998-09-25
Granted: 2005-06-07
Abstract: A wireless communication device automatically and seamlessly switches to an alternate, available system when it is unable to complete a call origination attempt, without requiring the user to take any affirmative actions to select the alternate system, the wireless communication device stores a list of preferred communication systems. The mobile station attempts to acquire (302) one of these preferred communication systems upon failure of the reverse link (300). If that is not successful (304), the mobile station attempts to acquire (306) a communication system most likely to provide service. If that is also not sucessful (308), the mobile station re-attempts acquisition of the current communication system. The mobile station also re-attempts (310) acquisition with one of the preferred communication systems after a predetermined idle time.

Abstract: A mud saver valve is described that features an outer housing that retains upper and lower valve pistons therewithin. The pistons coordinate to provide a check valve so that fluid, such as drilling mud, is permitted to flow in one direction while under pump pressure and works as a relief valve in the event of excessive wellbore pressure when the pump is turned off. Both pistons are provided with apertured plates that selectively define fluid passages through the valve. In the described embodiment, the valve also includes a frangible vent cap that is self-securing and easily replaceable. The cap permits venting of excessive downhole pressures.

Title: Syringe pumps
Inventor: COBB ANTHONY RICHARD
IPC: A61M5/00
Filed: 2000-05-11
Granted: 2008-07-22
Abstract: Syringe pumps have a drive mechanism for moving the plunger of a syringe along a barrel. In the present invention, ears at the rear of the barrel engage against a wall on the pump and an L shape clamp arm is urged against the ears by a spring. The clamp arm is mounted about an axis at right-angles to the syringe and is articulated at a point along its length. A lever having a flag at one end is pivoted about a horizontal axis by movement of the arm and moves relative to an optical sensor so that the output of the sensor indicates whether the syringe is correctly loaded in the pump. The clamp arm is rotated away from the barrel by the drive mechanism during loading of the syringe.

Title: Battery recharging device and method and an automatic battery detection system and method therefor
Inventor: FISCHER DANIEL M
IPC: G01R31/36
Filed: 2001-10-26
Granted: 2008-07-22
Abstract: A system includes a recharging device to which an electronic hand-held device powered by a battery can be connected. A controller associated with the recharging device performs a method of internal-device battery cell detection, i.e., distinguishing between NiMH/NiCd and other types of cells in the battery, before recharging the battery. A method determines the cell chemistry without any modifications to the battery and/or without any user input by performing tests on the battery. The tests include a Battery Voltage Test, an Internal Resistance Test, and a Timed Voltage Test. The testing is performed through a combination of hardware and software in the charging cradle. By performing the tests in a preferred order, detected alkaline, lithium, rechargeable alkaline, and carbon-zinc cells, damaged NiMH and NiCd cells, and close to fully charged NiMH and NiCd cells cause termination of a recharging operation before damage to the device or battery is sustained, without requiring input from a user.

Filed: 2000-09-20
Granted: 2007-03-27
Abstract: A method of directly fabricating metal parts with surface features only requires first preparing a mold (50) of the desired metal part. A powder blend is poured into the mold (20), which includes a base metal, a lower melting temperature alloy of the base metal, and a polymer binder.

Title: System and method for liquefied petroleum gas recovery
Inventor: MEALEY W BRENT
IPC: C10G5/06
Filed: 2002-05-30
Granted: 2008-08-26
Abstract: An improved process for recovery of liquefied petroleum gas from a raw natural gas feed stream, capable of achieving ultra high propane recovery yields, thereby separating substantially all of the propane and heavier hydrocarbon components from a predominantly methane and ethane feed gas stream. The process includes steps to liquefy all of the propane and heavier components and part of the methane and ethane components by cooling, condensing, and absorption. The residual feed gas containing the methane and ethane components, being the final gaseous product stream. The liquefied portion of the feed is separated and then fractionated in a distilling unit to produce a propane and heavier product stream. The distilling unit overhead vapors are cooled and condensed in two steps to provide reflux for the top of the deethanizer and for the feed gas absorption.
