摘要： A valve cover for enclosing an underground area surrounding the actuating mechanism of a flow control valve. The valve cover includes a body having a structure configured to position the valve cover in a desired orientation relative to the flow control valve. This positioning structure may be at least partially elastomeric, and configured to resiliently deform and urge against the flow control valve when the valve cover body is placed over the valve actuating mechanism. This maintains the valve cover body seated in a centered, leveled orientation relative to the valve actuating mechanism. The positioning structure may also be formed as a spacer configured to contact the valve actuating mechanism itself and space the actuating mechanism from the valve cover body. The valve cover body is configured so that, when it is installed, a valve tool may be freely inserted into the enclosed underground area and operatively engaged with the valve actuating mechanism.

摘要： Method and apparatus are provided for moving perforated continuous paper (10) through a dual axis printer (12), with both axes (14, 30) driven, while regulating the feed with the perforations and maintaining a controlled tension (38a) in the paper between the two driven axes. The novel approach in this invention is the addition of a set of spring-loaded friction surfaces (56a-62a), incorporated into a gear transmission (50), which limit the amount of torque which can be transmitted to the unregulated drive axis, with the direct effect of controlling the tension in the paper between the two axes.In order to create this tension, the unregulated axis is driven at a slightly greater speed than the regulated axis (with speed measured in terms of inches of paper per revolution of the driven gear (20)). In normal operation, the slack in the paper is taken up, to the point at which the tension is at the correct level, and then enough slip occurs at the friction surfaces to drive the same amount of paper at both the regulated drive (16) and unregulated drive (32). The unregulated drive is only overdriven slightly (e.g., about 0.2%) to allow accurate feeding of single sheets (which are not driven by the regulated drive). This slight overdrive requires only minimal slip at the friction surfaces when driving continuous paper and thus keeps the amount of wear small.
摘要翻译： 提供了用于通过双轴打印机（12）移动穿孔连续纸（10）的方法和装置，其中两个轴线（14,30）被驱动，同时用穿孔调节进给并且保持纸张中的受控张力（38a） 在两个从动轴之间。 本发明中的新颖方法是加入一组弹簧加载的摩擦表面（56a-62a），该弹簧加载的摩擦表面（56a-62a）被结合到齿轮传动装置（50）中，该齿轮传动装置（50）限制可传递到未调节的驱动轴的转矩的量， 控制两轴之间纸张张力的直接效果。 为了产生这种张力，未调节的轴线以比调节轴线稍快的速度被驱动（以从动齿轮（20）的每转一英寸的纸张的速度来测量）。 在正常操作中，纸张的松弛被吸收到张力处于正确水平的位置，然后在摩擦表面发生足够的滑动，以在调节驱动器（16）处驱动相同量的纸张， 和非稳压驱动器（32）。 未调节的驱动器仅稍微过载（例如，大约0.2％），以允许精确地馈送单个片材（其不被调节的驱动器驱动）。 这种轻微的超速传动在驱动连续纸时只需要在摩擦表面上的最小滑动，从而保持磨损量较小。

摘要： The invented printer includes a paper drive and mechanisms which hold paper in proper alignment in the drive. Specifically, it includes a pressure plate capable of bringing a sheet of paper into contact with a drive roller so that the paper is properly aligned, a wrapper which keeps paper in proper contact with the drive roller, a media edge contactor that presses against paper, a carriage guide support which helps to insure proper alignment of the paper during printing, and a back-out restraint to prevent paper from backing out of the printer.

摘要： An active paper drop mechanism (20) for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members (22) associated with opposed walls (14) of a horizontal-disposed output collection tray (12) for receiving sheets (10) of printed media.In particular, each rail member is provided with return spring (26) that act to maintain the rails in a closed position. In that position, the rails support a sheet of the print medium during the printing operation, thus giving the ink on the previously printed-on sheet (10') time to dry.The rails are provided with a wing member (32) and are pivotally secured (38) in the floor of the output tray, with the pivot point spaced inwardly from the wing member. Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess (24) provided in the side of the output tray. This provides sufficient clearance for the sheet to drop into the output stack. Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.

摘要： A novel ink-jet printer (10) is provided. The print provides both paper supply tray (12) and paper collection tray (18) in the front (14) of the printer for ease of paper handling and reduced footprint. The paper collection tray is provided with a pair of opposed output rails (22) which support a sheet of paper (16c) during printing to permit ink on a sheet of paper (16b) previously printed to dry. A paper handling mechanism is provided which eliminates a sheet pickup motor and associated elements. The paper handling mechanism is configured to pick off a sheet of paper from a stack of input paper, bring it around paper drive rollers (24) onto a platen (26), where the printing operation, employing a printhead cartridge (32), occurs. The printer further includes a service station (230) for clearing clogged nozzles in the printhead (33) and removing bubbles therefrom, for covering the nozzles with a protective cap (266), and for wiping contaminants off the nozzles. Reference pads (200) are provided for aligning and securing the printing cartridge in a carriage (35). The carriage is associated with a carriage guide (27), to which the carriage and print medium are referenced. The resulting printer is easy to manufacture, has reduced complexity by eliminating components in the paper drive mechanism and is lower in cost.
