摘要： A building sheet includes a substantially flat board having a front surface, a back surface and a thickness defined therebetween. At least one of the front and back surfaces defines a surface direction. The thickness defines a thickness direction that is substantially perpendicular to the surface direction. Recesses are formed in at least one of the front and back surfaces. The recesses have a maximum dimension in the surface direction of less than 3/8 inch, such that each recess is too small to receive a head of the fastener.

摘要： Dissolved components of a liquid sample are recovered for analysis by delivering the sample to a concentrator comprising a cylindrical receptacle into which an uncontaminated gas, such as air, is introduced in a direction tangentially of the cylindrical wall. The gas is under sufficient pressure to effect swirling of the gas and liquid sample and atomization of the sample to rapidly evaporate the same and cause a residue containing the dissolved components to be deposited on the interior surface of the wall. A reconstituting solvent is then admitted to the receptacle to dissolve the residue and provide a reconstituted, concentrated sample for analysis. If desired, the sample may be concentrated to a given volume rather than to complete dryness. In nonlaboratory applications, a dilute liquid substance may be processed by rapid evaporation to provide a final product of desired concentration.
摘要翻译：通过将样品递送到包括圆柱形容器的浓缩器中来回收液体样品的溶解成分，通过圆柱形容器将未受污染的气体（例如空气）沿着与圆柱形壁相切的方向引入其中。气体处于足够的压力下以产生气体和液体样品的旋转和样品的雾化，以使其快速蒸发，并使含有溶解组分的残余物沉积在壁的内表面上。然后将重构的溶剂进入容器以溶解残余物并提供重构的浓缩样品用于分析。如果需要，可以将样品浓缩至给定体积而不是完全干燥。在非实验室应用中，可以通过快速蒸发处理稀液体物质以提供所需浓度的最终产物。

摘要： The present invention includes a screw tip for an extruder screw for effecting mixing in an extruder. The screw tip has a shaft portion and at least one mixing element ring connected to the shaft portion, or a mixing element having an aperture therethrough, or both. The mixing element may have two legs connected by a top portion with the aperture between the two legs to allow flow of extrudate therethrough.

摘要： The deflection of decking planks under load is tested using a portable deflection measurement instrument, after installation of the planks over spaced joists. The instrument has a bridge on support legs spaced to rest on the deck at points apart from a span between joists of one or more planks to be tested. The legs can rest on planks laterally adjacent to the plank(s) under test, so the bridge straddles over the plank, or the bridge can be cantilevered or can rest on the tested plank but at points beyond the span to be tested. A contact foot or tup is movably mounted on the bridge and coupled to a platform or similar receptacle by which weight is applied to the plank. The resulting displacement between rest and loaded states is measured using a distance scale, and applied as a function of the span length and loading criteria to assess the deck structure. In one embodiment, the bridge has handle rails whereby a user moves and places the bridge, and which rails assist in permitting the user to step, kneel or otherwise apply his/her body weight against the plank via the tup.
摘要翻译：在铺设木板之后，使用便携式偏转测量仪测试载荷下的甲板板的挠度。仪器具有支撑腿上的桥梁，间隔开，以便在要测试的一个或多个木板的托梁之间的距离处的位置处搁置在甲板上。腿可以靠在被测板上横向邻近的木板上，所以桥跨过木板，或者桥可以是悬臂的，或者可以搁置在被测试的板上，但是在待测试跨度的点上。接触脚或托板可移动地安装在桥上并且联接到平台或类似的容器，通过该平台或类似的容器将重物施加到板条。使用距离刻度测量在静止和负载状态之间产生的位移，并作为跨度长度和载荷标准的函数来应用以评估甲板结构。在一个实施例中，桥具有手柄轨道，由此使用者移动和放置桥梁，并且哪个轨道有助于允许使用者通过该托板将他/她的身体重量抵靠在板上。
