Abstract: A system and method for monitoring and maintaining loading of a yaw brake assembly for use with windmills. A bolt assembly attaches to the yaw brake assembly and provides a compressive load to a brake piston within the yaw brake assembly. A load indicator attached to the bolt assembly provides a measurement of load applied to the brake piston by the bolt assembly.

Abstract: A load indicator apparatus which is compact, portable and detachably mounted on the tie-rod. The load indicator apparatus includes a first reference fixture configured for attachment at a first position on the tie-rod, a second fixture configured for attachment at a second position on the tie-rod and an elongation gauge extending between the first reference fixture and the second fixture and configured to measure displacement of the second fixture relative to the first reference fixture during elongation of the tie-rod. A displacement transducer is connected to the second fixture to measure a capacitance value proportional to the loading acting on the tie-rod and transfers it to a load monitoring unit which translates the measured capacitance into a visual load reading and an electronic load output value.

Abstract: A mattress encasement with improved bed bug protection includes an encasement body configured to cover a mattress and a zipper disposed at an opening in the encasement body and movable between an open condition permitting insertion and removal of the mattress and a closed condition preventing bed bugs from traversing the zipper. The zipper has a zipper head and a zipper pull pivotable on the zipper head. A clasp is at least partly fixed to the encasement body. A hook-and-loop fastener is associated with the encasement body and the clasp for locking the zipper pull to the clasp with the zipper in the closed condition to prevent movement of the zipper head and opening of the zipper.

Abstract: A fabric includes a synthetic leather and a substrate containing Lyocell. The substrate backs and adheres to the synthetic leather. A method for producing a fabric includes providing a substrate containing Lyocell and adhering a synthetic leather to the substrate containing Lyocell. The synthetic leather may be formed of polyurethane or polyvinyl chloride.

Abstract: A coverlet includes a first back layer having edges, a second middle layer having edges and a batting layer having edges and being disposed between and quilted to the first and second layers, A third face layer has edges, covers the second layer and is stitched to the first and second layers and to the batting layer. A binding, preferably between ½ and 1 inch in width, covers all of the edges. The first, second and third layers are all formed of the same fabric, especially a lyocell blend. The batting layer is preferably a lyocell blend and in particular a blend with polyester. A method of producing the coverlet is also provided.

Abstract: A woven fabric includes a warp formed of natural or manmade fiber and a weft formed lyocell fiber or a blend of lyocell fiber and at least one other fiber.

Abstract: An electrosurgical generator apparatus controls a variable output signal to electrodes. The generator apparatus operates in a cut mode, a coagulation mode or a stimulate mode. The generator apparatus comprises a DC power supply that provides regulated low voltage and high voltage outputs and a radio frequency (RF) waveform generator circuit that provides pulse duration modulation (PDM) of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes. A control circuit controls a variable output signal to electrodes used in electrosurgical procedures. The control circuit comprises a DC power supply circuit that provides regulated low voltage and high voltage outputs and an RF waveform generator circuit that provides pulse duration modulation of a carrier signal. The carrier signal directly affects the variable output signal to the electrodes.

Abstract: A process for antiquing fabric and fabrics produced are disclosed. The process achieves a worn, distressed, and faded look to the fabric. The process may be used for creating fabrics having an antiqued, worn or weathered look. In the process, the fabric is treated with a dispersant leveling agent, the treated fabric is dyed and the dyed fabric is rinsed with a softener. The fabric may be bagged during the process to assist in achieving the antiqued look.

Abstract: A method is provided for making an electrode tip for use in a bipolar electrosurgical instrument from a single flat blank of metal. The method uses a photo chemical machining process. The resultant electrode tip has a generally loop shaped working portion. Use of the flat blank of metal results in electrodes having working portions with sharp edges in cross-section. The working portions emit concentrated energy in the radial direction.

Abstract: Briefly stated, the present invention comprises a resuscitation mask for administering artificial respiration to a patient. The respiration mask has a container for defining an interior region between the container and the face of the patient. Two conduits are provided through the container wall in order to define two air flow passageways which are in fluid communication with the internal region. A valve is disposed in one air flow passageway for permitting air flow into the internal region and preventing air flow from the internal region. A vent is provided to reduce pressure within the internal region in response to an increase in pressure within the internal region. The container is generally cup-shaped and, in the preferred embodiment, it is formed with a cylindrical member coupled to the one-way air flow conduit. The other airflow passageway is adapted to be detachably coupled to an oxygen source.

Abstract: Cementitious compositions useful as lightweight aggregates are formed from a blend of spent bed material from fluidized bed combustion and fly ash. The proportions of the blend are chosen so that ensuing reactions eliminate undesirable constituents. The blend is then mixed with water and formed into a shaped article. The shaped article is preferably either a pellet or a "brick" shape that is later crushed. The shaped articles are cured at ambient temperature while saturated with water. It has been found that if used sufficiently, the resulting aggregate will exhibit minimal dimensional change over time. The aggregate can be certified by also forming standardized test shapes, e.g., cylinders while forming the shaped articles and measuring the properties of the test shapes using standardized techniques including X-ray diffraction.

Abstract: An electrosurgical bipolar RF generator apparatus includes a bipolar electrode. An aperiodic sequence of uniform width bursts of a high frequency signal are electronically synthesized. Substantially identical decaying amplitude envelopes are impressed on the bursts of the high frequency signal. Each of the envelopes has a predetermined rate of change from a preselected initial amplitude. The impressed bursts of the high frequency signal are applied to the electrode. The electrical apparatus operates in a cut mode or a coagulation mode. The apparatus includes a power supply for providing a variable DC voltage, a short circuit detect circuit for detecting a short circuit at the bipolar electrode, and an open circuit detector for detecting an open circuit at the bipolar electrode.

Abstract: A wood burning stove, a free standing fireplace or fireplace insert is constructed to receive one of three possible types of inserts to make the unit adaptable to a convection, hot air or hot water heating system. The wood or like fuel combustion rate is automatically controlled by a temperature sensor and draft control system. The insert may be a baffle structure, an air to air heat exchanger or an air to water heat exchanger.
