Abstract: A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. A damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention.

Abstract: The present disclosure describes a sound attenuating flooring system. The sound attenuating flooring system has a subfloor, a sound attenuating material overlaying and contacting only a portion of the subfloor, and an overlayment. The sound attenuating material has a first surface and second surface. The first surface is defined by a plurality of outwardly projecting hollow protrusions. The second surface is defined by a plurality of open recesses corresponding to the plurality of outwardly projecting hollow protrusions. The overlayment overlays the second surface of the sound attenuating material.

Abstract: A semiconductor processing chamber may process wafers by submerging the wafers in a liquid. To determine when the liquid is free of disturbances or contaminants and thus ready to receive the next wafer, a camera may be positioned to capture images of the liquid after a wafer has been removed from the liquid. A controller may provide the images of the liquid to a neural network to determine when the liquid is ready based on an output of the neural network. The neural network may be trained to identify disturbances, such as ripples, bubbles, or contaminants in the liquid. The controller may then begin controlling the next semiconductor process and submerge the next wafer.

Abstract: The present disclosure describes a contiguous sound attenuating panel system. The sound attenuating panel has a top surface, a bottom surface, a first end, a second end, an adhesive strip on the top surface of the first end, and an engagement flap on the top surface of the second end. The adhesive strip has a first edge and a second edge. The second edge is located further from the first end than the first edge. When installed, the first end of a first sound attenuating panel abuts and is substantially coplanar with the second end of a second sound attenuating panel. The width of the engagement flap of the second sound attenuating panel terminates substantially at the location of the second edge of the adhesive strip of the first sound attenuating panel such that the engagement flap contacts and substantially covers the adhesive strip.

Abstract: Disclosed is an embed pan suitable for use with railing embed plates. Railing embed plates are commonly attached by bolts to balcony decks as supports for balcony railings. The disclosed embed pan provides a watertight seal around railing embed plate.

Abstract: A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. A damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention.

The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. As the desired weight of an ingredient is added to the mixing chamber, the computer slows and then stops the inflow of the current ingredient being loaded via broadly variable control of the loading of the ingredients. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. Further, a damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured.

Abstract: The composite material multilayered membrane of the present invention is sound insulating and sound-absorbent, acting as sound deadening insulation for noise impacts, mainly but not exclusively to be used in flooring, and in particular under the slab in floating floors, with the aim of reducing the transmission of noise into the below room. This membrane includes several layers, which include at least one polymeric monofilament three dimensional mat, at least one resilient mat, and at least one topping layer of waterproofing, breathable or not, tissue. This multilayered membrane with a thickness under a weight of 2 kPa of at least 8 and maximum 15 mm, preferably 10-12 mm, so as to achieve a normalized noise level in the disturbed room Lnw below 50 dB, or an impact insulation class of at least 60 points.
