    • A method is provided for effecting a color change in wood or a wood-grained article, and the article prepared thereby. The method includes the steps of applying to a nitrocellulose-finished wood article a composition that includes a water-based dye or pigment and a water-based varnish or lacquer over the nitrocellulose coating, without physically or chemically stripping the nitrocellulose layer. In an alternative embodiment, a wood-grained article is refinished by application of the water-based dye or pigment and a water-based varnish or Lacquer to its surface.
    • 提供了一种用于实现木材或木纹制品中的颜色变化的方法,以及由此制备的制品。 该方法包括以下步骤:在硝化纤维素成品木材制品上,在硝酸纤维素涂层上包括水性染料或颜料以及水性清漆或漆,而不物理或化学地剥离硝酸纤维素层。 在替代实施例中,通过将水性染料或颜料以及水性清漆或漆覆盖在其表面上来提炼木纹制品。

    • A windshield repair device comprising a vacuum cup with a built-in piston and cylinder assembly is characterized by a transverse opening in the cylinder so that when the piston is partly withdrawn, gas bubbles can be drawn out of the repair liquid by the vacuum holding the cup in place against the glass. In operation, after the bubbles are removed from the liquid, the piston is moved toward the glass. The piston closes off fluid communication through the transverse opening in the cylinder and as it moves further toward the glass, it forces repair liquid into the damaged area. One end of the cylinder is provided with a sealing ring which bears against the face of the windshield to provide a seal. The cylinder is used as a reservoir for repair liquid, and allows gas bubbles to be removed from the liquid by the vacuum holding the cup in place. The piston has a pointed projection at its end which bears against a separated cone of glass in the damaged area and breaks the seal between the cylinder and the face of the windshield when pressure in the repair liquid approaches a level such that it is likely to cause permanent damage by delamination of the windshield.
    • 一种包括具有内置活塞和气缸组件的真空杯的挡风玻璃修复装置的特征在于气缸中的横向开口,使得当活塞部分地被抽出时,气泡可以通过真空吸入维修液中,保持 杯子在玻璃上的位置。 在操作中,在从液体中除去气泡之后,活塞向玻璃移动。 活塞通过气缸中的横向开口封闭流体连通,并且当其进一步向玻璃移动时,其迫使修复液体进入损坏区域。 气缸的一端设置有密封环,该密封环抵靠挡风玻璃的表面以提供密封。 气缸用作修复液体的储存器,并且通过将杯保持在适当位置的真空使气泡从液体中除去。 活塞在其端部具有尖端的突起,其在损坏的区域中抵靠分开的玻璃锥体,并且在维修液体中的压力接近可能导致的水平时,破坏气缸与挡风玻璃的表面之间的密封 挡风玻璃分层永久性损坏。

The invention permits the cylinder itself to be used as a reservoir for repair liquid, while allowing gas bubbles to be removed from the liquid by the vacuum holding the cup in place.

    • An analytical toilet is disclosed with a bowl adapted to receive excreta, a conduit for transporting a liquid excreta sample from the bowl, and a liquid reagent source. The analytical toilet also includes a microfluidic chip that has a sensor configured to detect at least one property of the excreta sample. The microfluidic chip also has an excreta sample path in fluid communication with the conduit and the sensor and a reagent path in fluid communication with the liquid reagent source and the sensor. The length of and number of channels in the sample path and the reagent path are selected so as to control the respective fluid resistance of the excreta sample and the reagent to thereby optimize the mixing and flow rates of the excreta sample and reagent into the sensor. There is also disclosed analytical toilet with a microfluidic chip having reagent path that includes a first and a second channel. The second channel is longer than the first channel. A valve, which is controllable so as to cause the reagent to flow through either the first channel, the second channel or both channels. As such, the fluid resistance of the reagent is controlled, to thereby optimize the flow rate of the reagent into the sensor.
