IPC: H04M15/00
Filed: 1993-11-29
Granted: 1997-03-25
Abstract: A tone burst generator where a continuous tone voltage is applied across two series-connected semiconductor switches each having an ON state and an OFF state. A first control circuit controls the state of the first switch and the variable impedance in an intermediate region between its ON and OFF states to cause gradual, well-defined OFF/ON and ON/OFF transitions of the first switch. As a result of these first switch transitions, a voltage tone burst is generated that has precisely defined edges to eliminate clicking noise. The continuous tone voltage is of only one polarity--it has a non-zero DC component and an AC component having a peak-to-peak variation less the twice the magnitude of the non-zero DC component. A second control circuit controls the state of the second switch and the variable impedance in an intermediate  region between its ON and OFF states to cause well defined ON/OFF and OFF/ON transitions of the second switch. The second switch OFF/ON transition reduces the voltage tone burst to have a substantially zero AC component.

Granted: 1999-06-29
Abstract: An adaptive clock recovery arrangement for deriving a synchronous clock from an asynchronous, packet stream such as an asynchronous transfer mode (ATM) cell stream. The deviation in the magnitude of information stored in a first-in-first-out memory is continually monitored, and the synchronous clock frequency, referred to as the adaptive line clock frequency, is adjusted in a plurality of modes, under the control of a processor. The adjustment is made in response to a detected increasing condition of the monitored deviation. The adjustment are open-loop adjustment made without continually adjusting the adaptive line clock frequency based on the monitored deviation. Damping is substantially reduced compared with"conventional" PLL arrangements because the open-loop adjustments result in a rapid frequency correction with perfect or nearly perfect deadbeat damping, i.e.without the frequency oscillations that continue after the correct frequency is reached in closed-loop arrangements.

Title: Cross-linkable thixotropic wood adhesive gel
Inventor: COLUMBUS PETER S
IPC: C09D131/04
Filed: 1995-02-15
Granted: 1998-11-24
Abstract: A cross-linkable water-based wood adhesive comprised of a critical mixture of from 0.10 to 0.75 by weight of a water-soluble, high-viscosity thickening agent polymer such as hydroxyethylcellulose, 0.05 - 0.40% by weight of a defoamer to dissipate foam quickly during manufacture, 25.00 to 45.00% by weight of solids of a self-cross-linking polyvinyl acetate polymer (treated with N-methylolacrylamide) dispersed in water, the polymer having a molecular weight of about 30,000 to about 300,000, 1.00 - 3.00% by weight of a plasticizer/coalescing agent such as 2,2, 4-trimethyl-1,3 pentanediol monoisobutyrate, 0.50 to 1.00% of an acidic catalyst, such as aluminum chloride, 4.00 to 12% by weight of fine particle-size wood fibers (soft or hard wood fibers or a mixture of both) and 0.10% by weight of a preservative.The viscosity of this adhesive gel will "break-down" when its container, e.g. a squeeze-bottle or flexible tube is finger-pressed resulting in a sufficiently low viscosity to allow for easy extrusion from the small orifices, approximately 0.10 inch diameter or a rectangular slit opening such as approximately 1/16" wide by 5/16"long of the adhesive application tips attached to such squeeze-bottles and flexible tubes. When pressure is released after the desired amount of adhesive flows out of the container, the adhesive quickly reverts very closely to its original gel state so that it will not "run" on vertical surfaces nor "spill" when used as a general purpose wood adhesive. This adhesive has sufficient wet tack to hold two pieces of wood together while still allowing repositioning of the pieces of wood before drying. In addition, since this product contains real wood fibers, its dry film is stainable and easy to sand.
