摘要： The invention is directed to improvements in existing liquid hand held spray guns which deliver liquid to a spray nozzle and have fixed or adjustable spray pattern adjustment of the liquid being dispensed from the nozzle. The improvements comprise the addition of a ball valve between the spray gun internal air flow passage and a container of liquid to be sprayed through the nozzle and a venturi assembly which attaches upstream in a series relationship between the pressurized air input to the gun and the source of pressurized air. The venturi assembly is adaptable to substantially all of the liquid spray guns of the type described and when installed reduces the pressure of the pressurized air entering the gun to 10 PSI or less to comply with governmental environmental pollution standards. With the venturi assembly attached to a given liquid spray gun, the ball valve is employed to provide a slight positive pressure to the container of liquid attached to the gun to control the flow of that liquid from the container into the nozzle. The use of the two assemblies together enhances the flow of liquid to the nozzle and provides environmental acceptable pressure standards to the now non-complying existing liquid spray guns.
摘要翻译：本发明涉及现有的液体手持喷枪的改进，其将液体输送到喷嘴并具有从喷嘴分配的液体的固定或可调喷雾图案调节。这些改进包括在喷枪内部空气流动通道和通过喷嘴喷射的液体容器之间添加球阀和文丘里组件，该文丘里组件以输入到枪的加压空气与源的串联关系连接上游的压缩空气。文氏管组件适用于基本上所有类型的液体喷枪，并且当安装时将进入枪的加压空气的压力降低到10PSI或更低以符合政府环境污染标准。当文丘里组件附接到给定的液体喷枪时，球阀用于向连接到喷枪的液体容器提供轻微的正压，以控制该液体从容器进入喷嘴的流动。使用两个组件一起增加了液体到喷嘴的流动，并为现在不符合现有的液体喷枪提供环境可接受的压力标准。

摘要： A coping for the top of a swimming pool wall. The coping consists of successive cap segments, each having a rigid grooved outer flange and an inner resilient flange having a locking groove facing the groove of the rigid flange. The segments are snapped on spaced elongated anchor plates secured transversely on the top wall of the pool enclosure. The segments are provided with locking recesses to lockingly receive the enlarged marginal bead of a waterproof pool liner, or alternatively, the liner may be clampingly secured between the anchor plates and the top wall of the pool enclosure.

摘要： A pack-off seal assembly 26 particularly suitable for use for purposes of effecting a seal between a wellhead housing 18 and a casing hanger 16. The subject pack-off seal assembly 26 is designed to be interposed between the cylindrical wall surface 18a of the wellhead housing 18 and that of a casing hanger 16 so as to be movable between a non-sealing position and a sealing position relative thereto in response to an actuating force of low torque magnitude being applied thereto. The pack-off sealing assembly 26 includes an upper metal seal 30 having downwardly extending lips 44, a lower metal seal 32 having upwardly extending lips 46, and a plurality of independent non-bonded elastomeric members 36, 38 of differing diameters suitably supported between the upper and lower metal seals 30, 32. In addition, the upper and lower metal seals 30, 32 are provided with first and second means, respectively, that are designed to be operative to insure the retrievability of the lower metal seal 32 from between the wellhead housing 18 and the casing hanger 16 should removal of the pack-off seal assembly 26 be necessitated. The latter first and second means are cooperatively associated one with another so as to be operable to establish a lost motion connection between the upper metal seal 30 and the lower metal seal 32 when the pack-off seal assembly 26 is moved in a first direction between the non-sealing and sealing positions thereof, and so as to be operable to establish a rigid connection between the upper metal seal 30 and the lower metal seal 32 when the pack-off seal assembly 26 is moved in a second direction between the non-sealing and sealing positions thereof.
摘要翻译：包装密封组件26特别适于用于在井口壳体18和套管悬挂器16之间实现密封的目的。主体包装密封组件26设计成插入在井口的圆柱形壁表面18a之间壳体18和套管悬挂器16的外壳18，以便响应于施加到其上的低扭矩幅度的致动力，在非密封位置和相对于其之间的密封位置之间可移动。包装密封组件26包括具有向下延伸的唇部44的下部金属密封件30，具有向上延伸的唇缘46的下部金属密封件32和具有不同直径的多个独立的未结合的弹性体构件36,38的上部金属密封件30，上下金属密封件30,32。另外，上金属密封件30和下金属密封件32分别设置有第一和第二装置，其被设计成可操作地确保下金属密封件32的可检索性在井口壳体18和套管悬挂器16必须去除包装密封组件26。后者的第一和第二装置彼此协同地相关联，以便当包装密封组件26沿第一方向移动时，可操作以在上金属密封件30和下金属密封件32之间建立空动连接其非密封和密封位置，并且当打包密封组件26沿着第二方向移动时，可操作以在上金属密封件30和下金属密封件32之间建立刚性连接，密封和密封位置。
