Title: High temperature/ultra-high pressure sterilization of low acid foods
Inventor: BAKER ROBERT
IPC: A23B7/005
Filed: 1996-12-02
Granted: 2005-04-12
Abstract: Method for sterilizing low acid foods using both ultra-high pressures and hi gh temperatures. The instantaneous temperature change that occurs when pressure is applied combines a high-temperature short-time process with ultra-high pressure to deliver a fast and therefore gentle thermal process to a pre-packaged product. The process involves heati ng a low acid food to a pre-pressurized temperature, subjecting the food to ultra-high pressure, which instantaneously raises the temperatur e of the food, and then releasing the pressure so that the temperature returns to the original pre-pressurized temperature. The method leverages the adiabatic temperature rise which occurs when the food is hydrostatically pressurized, coupled with the lethality of the pressure, to achieve appropriate sterilization conditions. The disclosure also includes low acid foods which have been sterilized using both ultra-hig h pressures and high temperatures.
Patent CA-2243024-C (CA)
Inventor: SPRINGER SERGE
IPC: E05F15/14
Filed: 1998-07-13
Granted: 2001-02-27
Abstract: The present invention is a bi-parting door system for transit vehicles. It has two doors mounted for movement in opposite directions and a motor for opening and closing them.      It has at least one lock having a lock member for locking the doors in a closed position. The lock member is biased toward the locking position and moveable to an unlocking position by an actuator controlled by a control system which also controls the motor. When the doors are closed they experience a biasing force tending to open them and this biasing force is reacted by the lock member to generate a load on the lock member which prevents it from moving as a result of a spurious signal to the actuator Unlocking of the doors requires a door closing signal to be received by the motor to remove the load from the lock member, as well as an unlocking signal to the actuator. Hence, the doors cannot be opened by any one spurious signal to either the motor or to the actuator.

Granted: 2003-04-15
Abstract: An independent distributed database system comprising a plurality of sites wherein all users at all sites work off-line with local data. All applicatio n transactions are against the local database only, and every site stores "all  and only" the data it needs. On-line transactions occur only in the background, including a periodical "synch" between sites that transmits any changes to data of interest to that site. If the background operations are interrupted or the network is temporarily unavailable, the user does not see  new changes made at other sites until the data link is available again, but is otherwise unaffected. It is a feature that no site acts as a "server" for an y other site. Some sites may store more data or have more users than others, b ut all sites are logically peers.

Title: Connector having surface mount terminals for connecting to a printed circuit board
Inventor: MICHAUX GWEN L
IPC: H01R12/57
Filed: 1999-06-30
Granted: 2005-03-29
Abstract: A connector having a set of terminals that are preferably coplanar and are used to connect electrical components, such as surface mount components, with a printed circuit board (PCB). The connector uses an insulative wafer to achieve and to maintain the coplanarity of the terminals. Initially, the terminals are overbent so that as the wafer is being placed in the connector housing, the terminals contact the wafer on a slope of the wafer. In other words, as the wafer is being mated with the connector housing, the wafer pushes against the terminals to establish coplanarity. Thus, the wafer works in conjunction with the terminals in the connector housing to establish coplanarity. Therefore, the connector supports the terminals for positioning while ensuring that the terminals are coplanar.
