Patent CA-2322418-A1 (CA)
Title: Process and double-belt press for the continuous production of board materials
Inventor: WOLFF HEINZ-PETER
IPC: B30B5/06
Filed: 1999-03-09
Abstract: A double-belt press has a press line in whose downstream section a heat-transfer medium is conducted to forming belts through channels in the supporting plates, the channels running transversely to the panel. This heat-transfer medium is not heated, but rather partially releases its heat in a heat exchanger for use in another assembly. In this way, the heat balance of the installation which includes the double-belt press is improved. The forming belts are supported on roller chains. The roller chains are subdivided in the direction of travel of the panel, thus reducing the transport of heat from the upstream section of the press line to the downstream section.

Patent CA-2341231-A1 (CA)
Inventor: HANSEN W PETER
IPC: C12Q1/06
Filed: 1999-08-20
Abstract: An instrument for analyzing and dispensing objects larger than about 70µm in diameter is based on a flow cytometer with a novel fluidic switch arrangement for diverting a portion of a sample stream in response to detector signals in a flow cell. The instrument is particularly adapted for dispensing multicellular test organisms like nematodes or large microspheres for use in screening large libraries of potential pharmaceutical agents. Hydrodynamic focussing is used to center and align the objects in the flow cell. The objects pass through a sensing zone where optical or other characteristics of the objects are detected. The detector signals are processed and used to operate a fluidic switch that is located downstream from the sensing zone. The fluid stream containing the detected objects emerges from the flow cell into air where a fluid stream controlled by the fluidic switch diverts portions of the stream containing no sample objects or sample objects not meeting predetermined characteristics. The undiverted sample stream deposits selected sample objects into a plurality of containers.

Title: Segmented optical switch
Inventor: AO ERIC RONG
IPC: G02B6/35
Filed: 2002-01-10
Abstract: In an effort to greatly decrease the insertion losses inherent in larger sized M × N optical switches, the present invention deals with minimizing the variation in the optical path lengths of optical beams passing through the switch. To accomplish this goal, the present invention relates to a segmented optical switch comprising four segments, two segments having input ports and two segments having output ports. The segments having output ports are separated from each other, and positioned on adjacent sides of the segments with input ports. Accordingly, the very short optical paths as well as the very long optical paths in the switch are eliminated, thereby minimizing the variation in the optical path lengths. Preferably, the switch is comprised of four identical segments, making manufacturing and supply costs less.

IPC: A01D41/127
Filed: 2002-03-19
Abstract: An agricultural combine having a supporting structure that is driven by ground engaging wheels at a harvesting speed by a propulsion assembly. The combine is also provided with a threshing assembly that is driven by a variable torque sensing drive. The variable torque sensing drive is manipulated by pressurized hydraulic fluid. A  hydraulic sensor in hydraulic communication with the variable torque sensing drive provides an actual hydraulic pressure signal that is directed to an electronic controller. An operator control in the operator's cab of the combine provides a loss rate signal that is also directed to the electronic controller. The electronic controller converts the loss rate signal into a desired hydraulic pressure signal. The electronic controller regulates the forward speed (harvesting speed) of the combine so that the desired hydraulic pressure signal is equal to the actual pressure signal. The harvesting speed regulation can be modified or overridden by moisture signals from a moisture sensor located in the feederhouse for sensing the moisture content of harvested crop.
