Title: A method of measuring a river horizontal average flow velocity
Inventor: CHANG HAK SOO
IPC: G01P5/24
Filed: 1999-07-16
Abstract: A method of measuring a horizontal average flow velocity at a plurality of depths using an ultrasonic beam to obtain the flowrate of a river comprises steps of emitting continuous ultrasonic beams along a selected flowrate measuring free crosssection from one skirt of a river and measuring a moving distance of paired ultrasonic receiving transducers spaced away in an interval from each other until the outputting voltages of the paired ultrasonic receiving transducers become equal to each other and then measuring a horizontal average flow velocity, in which the paired ultrasonic receiving transducers are electrically connected to differential amplifiers in order to measure the position at a moment that their outputting voltage differences becomes zero, and furthermore steps of testing and correcting an apparatus for performing the method.

Title: Fast, environmentally-stable fiber switches using a sagnac interferometer
Inventor: DAVIS MONICA K
IPC: G02F1/35
Filed: 1999-07-30
Abstract: A fast, environmentally-stable fiber switch uses a Sagnac interferometer having an active fiber portion located asymmetrically in the loop of the interferometer. A pump pulse is applied to the interferometric loop and acts upon the active fiber portion to cause a change in its refractive index either by a thermal effect or by a non-thermal nonlinear effect. Because the active fiber portion is located asymmetrically in the loop, the change in refractive index of the active fiber portion is seen by the clockwise propagating light signal and the counterclockwise propagating light signal at different times, thus causing a temporary difference in the phase changes experienced by the two counterpropagating light signals. The temporary difference in the phase changes causes the two light signals to combine constructively at a switched output port of the input/output coupler of the interferometric loop until the phase changes of the two signals are again the same, at which time the signals combine at an unswitched output port of the coupler. The on-time of the switch is set primarily by the length of the Sagnac loop, and the fall time, which is caused by the Sagnac architecture, can be fast, even with a relatively slow active fiber.

Patent CA-2285760-A1 (CA)
Inventor: STONE HAROLD S
IPC: G06F9/38
Filed: 1999-10-12
Abstract: A method for prefetching structured data, and more particularly a mechanism for observing address references made by a processor, and learning from those references the patterns of accesses made to structured data. Structured data means aggregates of related data such as arrays, records, and data containing links and pointers. When subsequent accesses are made to data structured in the same way, the mechanism generates in advance the sequence of addresses that will be needed for the new accesses. This sequence is utilized by the memory to obtain the data somewhat earlier than the instructions would normally request it, and thereby eliminate idle time due to memory latency while awaiting the arrival of the data.

Title: Truck rear door opening mechanism
Inventor: VADER SCOTT J
IPC: E05D15/46
Filed: 2000-09-25
Abstract: A four bar link is provided between a walled cargo area of a truck and a rigid rear cargo door. The effective length of the lower link of the four bar linkage is longer than that of the upper link such that the motion of the door is generally up and over the top of the truck body. An eccentric cam is joined to the upper link with a tensioned spring extending around the cam such that the spring slackens as the door opens. The cam is configured so that, as the door is opened, the spring slackens more slowly initially then more quickly. This allows the door to be moved initially mostly outwardly before moving significantly upwardly and still be effectively counterbalanced throughout its motion.

Title: Process for controlling scale in the sugar process
Inventor: KUZEE Hendrika
IPC: C13B25/00
Filed: 1999-02-22
Abstract: The deposition of calcium salts, including calcium carbonate and calcium oxalate and the formation of foam, during the evaporation of sugar streams can be prevented or restricted by adding 0.1 - 200 ppm of a carboxyalkylfructan that contains 0.5 - 3 carboxyl groups per monosaccharide unit, 0.4 - 2.5 of which carboxyl groups are in the form of carboxyalkyl groups, to the sugar streams. The carboxyalkyl groups are, in particular, carboxymethyl groups. The other carboxyl groups can be carboxyl groups obtained by oxidation. The carboxymethylfructan gives comparable results to polyacrylates, which are less desirable from the standpoint of health and the environment.
