Title: Classification of splinters and wood chips
Inventor: OTTOW MANFRED
IPC: B07B7/08
Filed: 2006-11-02
Abstract: The invention pertains to a method and a device for classifying splinters and wood chips. Splinters and wood chips accumulating in a saw mill are usually subjected to a classification process, i.e., the initial mixture of splinters and wood chips of different sizes is separated in accordance with particle size or settling velocity in a large-scale separation process. The inventive device consists of a centrifugal classifying unit, a countercurrent classifying unit, a separating funnel for the coarse fraction and a separating cyclone for the fine fraction. A gas or a gas mixture is circulated in the system by means of a blower. It is tangentially introduced into the lower classifying chamber, initially flows through the countercurrent classifier, through the gaps between the blades of the centrifugal classifier and then into the separating cyclone before being returned to the blower.

Patent CA-2582475-A1 (CA)
Title: Fluidic cassette detection mechanism
Inventor: WILLIAMS DAVID LLOYD
IPC: A61F9/007
Filed: 2007-03-23
Abstract: A fluidic cassette detection mechanism is used for detecting the presence of a cassette at a certain position within a fluidic module. When the cassette is inserted into the fluidic module to a certain position and orientation, the detector mechanism senses the presence of the fluidic cassette and provides an appropriate signal to the system software. The system software can then command the closing of the mechanism, which holds the cassette during a procedure. The fluidic cassette detector mechanism can comprise a number of mechanical probes, optical interrupt switches, and miscellaneous components including springs and screws. The probes extend beyond the face of the fluidic module faceplate and beyond the rear stops of the clamps. When the fluidic cassette is inserted into the fluidic module far enough to sufficiently move the probes, the probes trip the switches to signal that the cassette is in the correct position and orientation for the clamping motion to begin. The correct position and orientation are sensed due to the use of probes in the mechanism. The probes are spaced sufficiently apart on a diagonal, and raised beyond the rear stops of the cassette clamps, such that when both probes are moved appropriately, the cassette must be acceptably parallel to the clamps, and in the correct position, for the cassette clamping motion to begin.

IPC: G01B9/02
Filed: 2005-11-18
Abstract: The Miniature Fourier Transform Spectrophotometer provides the capability, in a miniaturized device, of determining the light absorption/transmission spectra of a collected sample of gas or liquid though Fourier Transform spectroscopy techniques. The device takes an optical input from an optical fiber, manipulates that light through miniature optical components, and launches it into a miniaturized Michelson interferometer with a scanning mirror that acquires the interferogram of the optical input. The interferogram can be processed to retrieve the spectrum of the input light. A novel multi-stepped micro-mirror operates as the optical path length modulator in the miniaturized interferometer. A unique monolithic beamsplitter/mirror combination provides for accurate alignment of the components and greatly simplifies product integration. The device is designed to cover various optical spectra of interest. During operation, the precision and accuracy of the microfabricated components in the device allow operation and resolution even at extremely low wavelengths. In addition, the miniaturized nature of the device allows it to be used in new and extremely space-constrained applications.

The glare signaling circuit ("GSC") may have a first input port in communication with the first input channel, a second input port in communication with the second input channel, a logic-or gate capable of producing an output signal when the logic-or gate detects that the first input channel or the second input channel indicates glare on the light receiving surface. The glare reducing circuit ("GRC") may be in communication with the logic-or gate, and may be capable of reacting when the logic-or gate produces the output signal. For example, the GRC may react by determining where on the light receiving surface glare exists.

Title: Device to perform equipment alignment
Inventor: ZUGRAVU LIVIU
IPC: B23Q41/04
Filed: 2007-11-23
Abstract: The alignment of machineries at the user's place can be a very tedious and lengthy operation.   This activity is: -Time consuming, because the operators have to watch for end effectors, which is always tedious and requires multiple iterations. -Expensive, because sometimes it requires equipment not readily available and many highly skilled operators, able to decide when the alignment operation has been completed. -Aligning process can also be dangerous, especially when heavy machines are involved or if machines have to operate in order to asses the alignment. -In case the equipment has to be rearranged, the whole setting operation has to be redone.  This invention creates the possibility to conclude the alignment operation in a fraction of the time required by the existing methods. The invention also offers the possibility to check at any time whether the machines still preserve the alignment or have changed their relative positions to each other.  This advantage promotes quality and eliminates equipment down time.   The invention consists of pair of blocks placed on adjacent pieces of equipment that need to be aligned. One block is placed on one machine and the other is placed on the adjacent one. These blocks, that make a pair, are pre-aligned and all that is needed to be done in order to align the equipment, is to recreate the alignment. In order to achieve maximum of precision, it is advisable to use multiple alignment blocks on every machine.
