Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to controlling tension in such continuous webs during the processing operation. Tension is controlled in a dancer control system by connecting a corresponding dancer roll to a servo motor or the like, sensing position, tension, and velocity parameters related to the web and the dancer roll, and providing active gain force commands to cause translational movement in the dancer roll to control temporary, short-term tension disturbances in the web. In some applications of the invention, the dancer control system is used to attenuate short-term tension disturbances.      In other applications of the invention, the dancer control system is used to create short-term tension disturbances.

Title: Gas, fire and earthquake detector
Inventor: ANDERSON GARY
IPC: G01V1/00
Filed: 1996-02-28
Abstract: A safety system for a building has an earthquake detector circuit for detecting ground accelerations exceeding a threshold acceleration/frequency curve dividing safe and hazardous ground accelerations throughout a predetermined frequency range. The earthquake detector includes an accelerometer for measuring linear acceleration along an axis, and for generating an acceleration signal indicative of a magnitude of the measured acceleration. A filter circuit produces a filtered acceleration signal from the acceleration signal. The gain/frequency characteristic of the filter circuit is a reflection of the threshold acceleration/frequency curve, such that ground accelerations falling on the threshold acceleration/frequency curve yield a filtered acceleration signal having a substantially constant value throughout the frequency range. Finally, a threshold circuit compares the filtered acceleration signal to a predetermined threshold voltage, and produces an earthquake detected signal indicative of the comparison result. The safety system can also include a gas detector circuit capable of detecting a gas in air, and generating a gas detected signal in response to detection of the gas. A high temperature detector circuit can also be provided for detecting a high gas temperature, and generating a fire detected signal in response to detection of the high temperature gas. A main unit including a microprocessor is responsive to the earthquake detected signal, gas detected signal and the fire detected signal, and generates a first control signal in response to any one or more of the earthquake detected signal, gas detected signal and the fire detected signal. A valve controller closes a gas valve to shut off a supply of gas in response to the first control signal.

Patent CA-2175075-A1 (CA)
Title: Pit membrane-broken wood drying method and apparatus
Inventor: ANDO MINORU
IPC: B27K5/00
Filed: 1995-10-12
Abstract: The present invention is intended to artificially break pit membranes in cell membranes of cells constituting wood and then to readily attain dryness of the wood. In view of the fact that one pit or the other pit of pits in the form of a pair is blocked with the torus 1 in felled wood to cause poor removal of water in cells, it is intended to prevent the blockage of the pit membrane, i.e., to break the pit membrane per se, thereby facilitating easy escapement of water in cells after the breaking. In the present invention, wood fuel is burned, and subject wood is allowed to stand in a treatment chamber filled with smoky wood gas generated by the combustion for a predetermined period of time, to expose the subject wood to far-infrared radiation and components contained in the wood gas. Further, ceramic material for multiplying far-infrared radiation or high-density lava is heaped in a combustion chamber with appropriate gaps left therebetween, thereby effecting heat reservation and further multiplication of far-infrared radiation. Accordingly, the subject wood is irradiated with a large amount of far-infrared radiation, thereby preventing the torus of the wood from blocking up one pit or the other pit of pits in the form of a pair to form gaps in the pits.
