A linear positioning apparatus has a positioning actuator assembly including a cylinder and movable piston to be used for moving a workpiece or a moveable worktable along a rectilinear path or thrust axis. The apparatus includes at least one stop member adjustably mounted on a support such as a plate or hub. To stop the worktable at a selected stop point, each stop member can be positioned to engage an object, for convenience referred to herein as a bumper, that is connected to the moveable worktable to halt movement when the correct position has been reached. The apparatus includes means such as an actuator operatively associated to provide relative aligning movement between the stop member and bumper for placing the bumper and a selected one of the stop members in alignment with each other. The support for the stop member, e.g., a plate or hub, includes a bore or passage that extends entirely through it for each stop member so that each stop member can project out through both sides of the support. Consequently, the stop member can be fully retracted or extended its full length with respect to the support.

Linear stopping and positioning apparatus

A fluid delivery device having a self-contained stored energy membrane for expelling fluids at a precisely controlled rate which is of a compact, laminate construction. The device also includes a novel adapter which is usable to fill the reservoir of the device using a compatable filling syringe apparatus which is mateable with the adapter.

A linear pneumatic actuator stopping and positioning apparatus has a pneumatic actuator connected to a worktable for moving the worktable along a rectilinear path as well as a selector shaft that is mounted for rotational indexing movement at one side of the actuator and is operatively associated with one or more extendible stop arms for selecting a stop arm located at a selected stop point so as to contact the worktable and stop the movement of the worktable at the stop point selected. The shaft can be mounted to allow it to be shifted along its own central axis for moving one or more sleeve members that are connected to the shaft a short distance for extending a stop arm to an operating position. In one form, a stop arm actuator and locking bar is positioned to be engaged by the sleeve and to press the stop arm to its extended position. In another form of the invention, a stop plate is mounted on the selector shaft for rotation with the shaft as the shaft is indexed one or more times through a predetermined arc for extending a lobe on the plate to an operating position in the path of the worktable to halt the worktable at a selected stop point. In a third form, the stop member is screw-threaded into a hub that is mounted on the selector shaft and can be threaded into or out of the hub for establishing a selected stop point.

An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, which, in cooperation with a thin planar base defines a fluid chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visual indication of fluid flow through the apparatus.

Modular worktable

Modular work table

A modular metal cabinet is described which includes vertical interchangeable support columns formed from sheet metal and having a pair of web portions at right angles to each other. A plurality of interchangeable hollow reinforcing box panels also formed from sheet metal are secured to the web portions of the columns by fasteners hidden within the box panels. Each box panel is composed of the central rectangular wall sections, parallel top and bottom walls, parallel side walls with coplanar tabs extending toward one another from the edges of the side panels and positioned in overlapping face-to-face relationship with the webs of the columns. The fasteners extend through the webs into the tabs to hold the panels in place.

A self-contained, self-actuating corner radius punch and die machine is described including a plurality of spaced apart side-by-side cutting edges arranged in transverse alignment above a worktable. A motive power actuator, e.g., a hydraulic cylinder is mounted below the worktable with its actuator rod extending upwardly through the table and being connected to the punch. A guide is provided for preventing the punch from tilting about a horizontal axis and a stiffening plate is secured to the punch to rigidify the structure and to serve as a support for the guide.
