    Abstract: A hydraulic backcheck valve system for controlling an opening cycle of a door closer has a housing with an interior chamber, at least one cylinder, and a piston that can reciprocate between a door closing stroke and a door opening stroke within the cylinder. One side of the piston faces a variable volume chamber in the cylinder and an opposite side of the piston faces the interior chamber of the housing. The backcheck valve system has a fluid passage with a port in fluid communication with the cylinder and an opening in fluid communication with the interior chamber of the housing. The port is blocked by the piston during at least part of the door opening stroke. A one-way valve is disposed in fluid communication with the fluid passage and permits fluid to flow freely during a closing cycle of the door closer and prevents fluid flow from the second passage during the opening cycle. A backcheck valve is disposed in fluid communication with the passage and with the variable volume chamber. The backcheck valve permits metered fluid flow from the second passage to the variable volume chamber during the opening cycle to control the opening cycle.

    Abstract translation: 用于控制门关闭器的打开循环的液压反向检查阀系统具有壳体，该壳体具有内腔，至少一个气缸和可在气门内的门关闭行程和门打开行程之间往复运动的活塞。 活塞的一侧面向气缸中的可变容积室，并且活塞的相反侧面向壳体的内部腔室。 反向检查阀系统具有流体通道，其具有与气缸流体连通的端口和与壳体的内部腔室流体连通的开口。 端口在门打开行程的至少一部分期间被活塞堵塞。 单向阀设置成与流体通道流体连通，并允许流体在门关闭器的关闭循环期间自由流动，并且防止在打开循环期间流体从第二通道流出。 反向检查阀设置成与通道和可变容积室流体连通。 反向检查阀允许计量流体在打开循环期间从第二通道流向可变容积室以控制打开循环。

    Abstract: A novel method for inhibiting oxygen corrosion in an oil well, and an emulsion useful therein. The method comprises introducing into the well a pourable emulsion comprising about 50 to about 95 volume percent discontinuous aqueous phase, about 5 to about 50 volume percent continuous oil phase, and a corrosion inhibiting amount of a composition comprising a corrosion inhibitor selected from among thiophosphates containing both oxygen and sulfur, pyrophosphates containing both oxygen and sulfur and mixtures thereof.

    Abstract: A continuous partially preprinted, preglued form suitable for subsequent envelope construction comprises a single web partially preprinted on one side, having detachable marginal feed hole strips parallel with each longitudinal edge, and transverse marginal lines of perforations defining individual envelope forms with two transverse lines of perforations defining fold lines intermediate the marginal lines. On the side of the web opposite the preprinting, a first transverse adhesive strip is disposed immediately adjacent one of the transverse marginal lines and a second transverse adhesive strip is disposed parallel to the first transverse adhesive strip intermediate between that strip and the adjacent fold line. Two first aligned longitudinal adhesive strips lie parallel to one of the longitudinal edges adjacent a marginal feed hole strip with one adhesive strip extending between the transverse adhesive strips and the other extending between the transverse fold lines. Two second aligned longitudinal adhesive strips lie parallel to and coextensive with the first two longitudinal adhesive strips and spaced a predetermined distance therefrom, and a longitudinal line of perforations extends between the two transverse fold lines a predetermined distance from the other of said longitudinal edges. The web may then be variable printed on the preprinted surface, detached along the transverse marginal lines of perforations, folded and sealed to form complete envelopes.

    Abstract: A door closer comprises a housing containing a cylinder and two movable pistons. When the associated door is opened, both of the pistons and the cylinder are moved relative to the housing to draw oil into the cylinder. Expulsion of oil from the cylinder through an orifice on closing of the door controls the closing movement.
