Patent CA-2406499-A1 (CA)
Inventor: STEPHENSON DWIGHT
IPC: B66F9/065
Filed: 2002-10-03
Abstract: An industrial lift truck has a boom that is raised and lowered by a first hydraulic actuator and a load carrier that is pivoted with respect to the boom by a second hydraulic actuator. In the event that the supply of hydraulic fluid for powering the actuators fails, the boom may be lowered by gravity by draining fluid from the first hydraulic actuator. To prevent a load from sliding off the load carrier as the boom descends, the load carrier is pivoted to maintain a substantially constant angular relationship to the ground. This is accomplished by selectively conveying fluid drained under pressure from the first hydraulic actuator into the second hydraulic actuator. Changes in the position of the boom are sensed and, in response, the flow of fluid into the second hydraulic actuator is controlled to produce corresponding changes in the load carrier position.

Title: Analysis of network performance
Inventor: RACHLEVSKI-REICH BENNY
IPC: H04L12/24
Filed: 2001-04-05
Abstract: A method for testing of a communication network (22), using a plurality of traffic agents (26, 28, 30) coupled to communicate via the network. The method includes transmitting a sequence of data packets via the network from a first one of the traffic agents to a second one of the traffic agents and recording arrival characteristics of the packets in the sequence, responsive to receiving the packets at the second traffic agent. The arrival characteristics of different packets in the sequence are compared so as to determine a measure of variability in transmission of the packets via the network.

Patent CA-2418341-A1 (CA)
Title: Ruggedized photomultiplier tube and optical coupling in armored detector
Inventor: MEDLEY DWIGHT
IPC: E21C35/22
Filed: 2001-07-18
Abstract: A photomultiplier tube and a method and apparatus for molding an optical coupler thereto are described. An optical coupler molding fixture includes a frame and a frame base. A photomultiplier tube is positioned within the frame and a frame base. A photomultiplier tube is positioned within the frame between a spring and a shim. The optical coupler is formed with a mold which is positioned against the shim. A cavity is created radially interior to the shim between the photomultiplier tube and the mold. The optical coupler is molded to a faceplate of the photomultiplier tube with the fixture oriented so that its longitudinal axis L is parallel to the ground. A clamping structure presses the mold against the shim and provides the optical coupler material a non-leak space in which to cure. The optical coupler material is injected into the mold through a fill hole, and may be injected at ambient temperature.  Curing time may range from one week at ambient temperatures to four hours at 65 ~C. The mold can be machined to create any form desired for the optical coupler. The shim can be sized and configured to allow for adjustment in the thickness of the optical coupler. The optical coupler may be as thin as less than 0.015 inches in thickness. If, for example, a thicker optical coupler is desired, the shim may be made thicker. The edge of the photomultiplier tube housing which abuts the shim is checked for its perpendicularity to the longitudinal axis L. Without perpendicularity, proper alignment of the photomultiplier tube is less likely.

Title: Method for producing precooked and dehulled masa flour
Inventor: SOSA FRANCISCO
IPC: A23L7/10
Filed: 2002-01-22
Abstract: Precooked and partially dehulled masa flour for tortilla and the lie is produced by pressure pre-cooking in a continuous process with saturated-steam.  The precooking effect corn hull hydrolysis and partial cooking with a lime solution, reduced kernel washing and solid loss in wastewater. Next, moisture content is stabilized, and the corn is ground and dried in a super-heated stream of air to produce a partial cooking, cooling and further drying of the dried-ground particles. Separating and recovering yields the fine grind or masa flour from the coarse grind which is segregated to isolate a hull fraction as corn hull waste. Reground coarse grind is sieved to produce further yield of the instant masa flour. The flour is well suited for use in making tortilla and other corn-based snack foods.
