摘要： A computer driven plotter pen includes a turret from which a any one of plurality of different types of pens may be selected. When the plotter determines that a pen has become spent, the spent pen is automatically removed by a pen transfer carriage from the pen turret and discarded. The transfer carriage then removes a fresh replacement pen of like type to the spent discarded pen from a magazine thereof, and installs the replacement pen in the turret which in turn installs it in the plotter pen carriage. No operator involvement is required.

摘要： A sling assembly for use in carrying shoulder weapons, such as hunting rifles, in a horizontal ready position. A sling strap is connected to sling swivels mounted on the weapon in the conventional positions at the bottom of the butt stock and forestock, by loops which encircle the butt stock and the front portion of the weapon. The rear part of the sling strap is fixed to the rear loop, which is long enough to surround the butt stock and to slip rearwardly off the butt stock as the weapon is raised to the shooter's shoulder. The front end of the strap is free to hang down beside the front portion of the weapon with only the front loop around the top of the weapon, where it does not interfere with use of the sights. Various ways are disclosed to attach the loops to sling swivels or to a handguard on the front portion of the weapon. In one embodiment a slide fastener holds the sling strap at a desired length but is adjustable using only one hand.

摘要： The plate feed apparatus of the present invention is comprised of a cylindrical carrier having air inlet holes located in its periphery which are connected to a vacuum source. A stack of plates is fed toward the carrier on a conveyor belt and each time one of the air inlet openings becomes aligned with the plates the front plate in the stack becomes affixed to the carrier and is rotated with it away from the stack. The plates then are released from the carrier for further handling. In order to prevent the plate being carried from striking the remaining plates a gap must be provided between them. In one embodiment this is accomplished by locating rollers, whose axes are parallel with the axis of the carrier, at the periphery of the carrier in positions which are rotationally ahead of the air inlet openings. In a second embodiment a pair of levers are mounted rotatably outwardly of the carrier sides. Rollers contact the levers at the proper rotational orientation of the carrier and rotate them rearwardly so that they contact the plates and move them away from the carrier. A return spring pulls the levers back toward the carrier. In both embodiments the forwardmost plate becomes free to move back toward the carrier as the air inlet opening becomes aligned with the plates. The vacuum then pulls the forward plate away from the stack thereby creating the necessary gap between it and the rest of the plates in the stack.
摘要翻译：本发明的送纸装置由圆筒状的载体构成，该圆柱形载体具有位于其周边的与真空源连接的进气孔。一堆板在输送带上被运送到载体上，并且每当空气入口开口中的一个与板对齐时，堆叠中的前板就固定在载体上并随着其离开堆叠而旋转。然后将板从载体上释放以进一步处理。为了防止板被携带而撞击剩余的板，它们之间必须有间隙。在一个实施例中，这通过将辊的轴线与载体的轴线平行的方式定位在承载件的周边处，其位置旋转地位于空气入口开口的前方。在第二实施例中，一对杠杆可旋转地安装在托架侧面的外侧。辊子以承载件的正确旋转方向接触杠杆并向后旋转，使得它们接触板并将其从载体移开。复位弹簧将杠杆向载体拉回。在两个实施例中，当空气入口开口与板对准时，最前面的板自由地朝向载体移回。然后真空将前板拉离堆叠，从而在其与堆叠中的其余板之间形成必要的间隙。

摘要： In the preferred embodiment of the present invention trimethylsilyl 7-trimethylsilyloxycarbonylaminodecephalosporanate was prepared by bubbling dry carbon dioxide into an anhydrous solution of trimethylsilyl 6-trimethylsilylaminodecephalosporanate and found to be a useful intermediate in the production of cefadroxil and cephalexin by its acylation in anhydrous media with the appropriate 2-phenylglycyl chloride hydrochloride. Other cephalosporins are produced by acylation of 7-trimethylsilyloxycarbonylaminoceph-3-em-4-carboxylic acids or esters having a variety of substituents at the 3-position.

摘要： A holder for releasable securement of cartridges in condition for simultaneous loading of the cartridges into the chambers of a revolver's cylinder. The holder comprises a cylindrical body having a plurality of axially extending, radially distributed cartridge-receiving bores adapted to align with and introduce the rounds into the revolver's cylinder chambers. The holder also includes a manually operated cartridge engagement member for axial and rotary movement within the holder body centrally of the bores and having a double star sprocket system whose lateral projections releasably lock each cartridge flange while laterally supporting each cartridge body within the holder in a position of parallelism with a center bore. The holder further includes protected means for releasing the double star sprocket system and thereby releasing the cartridges, when the cartridge ends are in the revolver's cylinder chambers, in response to the pressing of the holder against the rear of the revolver cylinder.

摘要： A ladder assembly for a work vehicle comprises a deck affixed horizontally just below an entry door of the cab. A yoke is pivotally joined to a support member of the deck for rotation about a vertical axis below the deck surface. The yoke has a pair of arms pivotally joined to an upper end of a ladder structure for allowing rotation of the ladder about a horizontal axis. A turnbuckle is coupled between the support structure of the deck and one stringer of the ladder while a mechanical actuator is operatively coupled to the ladder's other stringer and to an arm of the yoke to which the other stringer is attached. Operation of the mechanical actuator moves the ladder reciprocally between a use position and stowed position where the stowed position is parallel to and immediately below the deck.

摘要： A robotic mower home finding system includes a charging station connected to an outer boundary wire loop, and a vehicle control unit on the robotic mower that directs a traction drive system to drive the robotic mower along a path offset a specified distance from an outer boundary wire loop toward the charging station. The vehicle control unit changes the specified distance randomly or incrementally so that the robotic mower does not take the same path to the charging station each time.
