    • A flowmeter apparatus and method for use in measuring the quantity of liquid beverage passing through a tubing, the apparatus including a flowmeter wheel adapted to be turned by the flow of beverage through the tubing. The flowmeter wheel is interposed in a light path between a light source and a light detector with a plurality of apertures in the flowmeter wheel permitting light passage through the light path to the light detector. Rotation of the wheel creates a series of light pulses that are detected by the light detector and are electronically counted to thereby provide an indication of the amount of beverage passing through the flowmeter and, correspondingly, the tubing.
    • 一种用于测量通过管道的液体饮料的量的流量计装置和方法,该装置包括适于被饮料流通过管道转动的流量计轮。 流量计轮被插入在光源和光检测器之间的光路中,在流量计轮中具有多个孔,允许光通过到光检测器的光路。 轮的旋转产生一系列由光检测器检测的光脉冲,并被电子计数,从而提供通过流量计的饮料量以及相应的管道的指示。

    • An advanced epoxy cationic resin useful as an electrodeposition coating having a charge density of from 0.2 to 0.6 milliequivalent of cationic charge per gram of resin is prepared by reacting in the presence of a suitable catalyst (A) a composition comprising (1) at least one diglycidyl ether of (a) an oxyalkylated aromatic diol or (b) an oxyalkylated cycloaliphatic diol or (c) certain oxyalkylated aliphatic diols and (2) at least one diglycidyl ether of a dihydric phenol with (B) at least one dihydric phenol and optionally (C) a monofunctional capping agent. Components (A-1) and (A-2) are employed in quantities such that from 10 to 75 weight percent of the diglycidyl ethers contained in component (A) are contributed by component (A-1), and from 25 to 90 weight percent of such glycidyl ethers are contributed by component (A-2). Components (A) and (B) are employed in such quantities that the resultant epoxy resin has an average epoxide equivalent weight of from 350 to 10,000. The terminal oxirane groups in the thus formed advanced epoxy resin are converted to cationic groups by reacting the resin with a nucleophilic compound and adding an organic acid and water.
    • 可用作电沉积涂层的先进的环氧阳离子树脂,其电荷密度为每克树脂阳离子电荷的0.2至0.6毫当量,在合适的催化剂(A)存在下,通过使组合物反应,所述组合物包含(1)至少一种 (a)烷氧基化芳族二醇的二缩水甘油醚或(b)烷氧基化脂环族二醇或(c)某些烷氧基化脂族二醇和(2)至少一种二元酚与(B)至少一种二元酚的任选的二缩水甘油醚 (C)单官能封端剂。 组分(A-1)和(A-2)的用量使得组分(A)中包含的10至75重量%的二缩水甘油醚由组分(A-1)和25至90重量份 这种缩水甘油醚的百分比由组分(A-2)贡献。 组分(A)和(B)的用量使所得环氧树脂的平均环氧当量为350至10,000。 如此形成的先进环氧树脂中的末端环氧乙烷基团通过使树脂与亲核化合物反应并加入有机酸和水而转化为阳离子基团。

    • A pressure resistant system for joining concrete pipes in an end to end relationship is disclosed. The first pipe terminates in a bell end and the second pipe terminates in a spigot end with the spigot end surrounded by a seal member and the inner surface of the bell also surrounded by a seal member. Each seal member has internal ribs which extend into and are embedded in the concrete pipe. The spigot end sealing ring includes an internal flap extending substantially perpendicular thereto across an internal offset face of the spigot and a lip extending across a portion of the end face. A rib of reduced length is disposed adjacent the lip and midway between the lip and the flap. In one embodiment the spigot and sealing ring defines a concave groove for receiving an O-ring seal, and in another embodiment the concave groove is replaced by an integral convex seal portion.
    • 公开了一种以端对端关系连接混凝土管的耐压系统。 第一管终止于钟形端,第二管终止于插口端,其端盖由密封构件包围,并且钟的内表面也被密封构件包围。 每个密封件具有延伸到混凝土管中并嵌入在混凝土管中的内部肋。 插口端密封环包括其内部翼片,其基本垂直于其延伸穿过插口的内部偏移面,以及唇缘延伸穿过端面的一部分。 减小长度的肋设置在唇缘附近并且在唇缘和瓣之间的中间。 在一个实施例中,插口和密封环限定用于接收O形环密封件的凹槽,在另一实施例中,凹槽由整体的凸形密封部分代替。
