Abstract: Self adjusting pliers for grasping a workpiece include first and second plier members each including a handle portion, a jaw portion, and an intermediate portion therebetween. The self-adjusting pliers include a first pivot pin about which the first and second plier members pivot permitting the jaw portions to converge on a workpiece and grasp the workpiece in response to initial movement of the handle portions toward each other. The self adjusting pliers further include a second pivot pin about which the pliers pivot once pivoting has been terminated about the first pivot pin so as to permit a further grasping force to be applied to the workpiece in response to continued movement of the handle portions toward each other. The second pivot pin is closer to the jaw portions than the first pivot pin to allow for a greater mechanical advantage to be obtained. The self adjusting pliers also include a biasing spring for biasing the handle portions away from each other and the jaw portions away from each other.

Abstract: A gas outlet apparatus (10) is configured to provide a medical gas outlet for a gas supply line (62). The apparatus (10) includes a front cover (12) formed to include a gas outlet opening (14), a back plate (24) coupled to the front cover (12), and a gas outlet barrel (30) having an inlet end, an outlet end (80), and a valve located between the inlet end and the outlet end (80). The apparatus (10) also includes a retention portion located on the back plate (24). The retention portion is configured to engage the barrel (30) adjacent the outlet end (80) to secure the barrel (30) to the back plate (24) and the cover (12) and with the outlet end (80) of the barrel (30) in alignment with the gas outlet opening (14) formed in the front cover (12).

Abstract: Pliers with self-adjustment capability for applying a grasping force to a workpiece and for augmenting the grasping force applied to the workpiece which include a first plier member, a second plier member, a first pivot, a second pivot and a first biasing spring. The first plier member includes a handle portion, a jaw portion, an intermediate portion, a coupling interconnecting the handle portion of the first plier member to the intermediate portion of the first plier member, and locking device. The second plier member includes a handle portion, a jaw portion, and an intermediate portion disposed therebetween. The first pivot includes a shifting slot portion, a transitional portion, and a positioning slot portion with a generally arcuate portion formed in said intermediate portion of the first plier member. The first pivot also includes at least one pivot member extending into, and movable within, the shifting slot portion, transitional portion, and positioning slot portion.

Abstract: Self adjusting pliers for grasping a workpiece include first and second plier members each including a handle portion, a jaw portion, and an intermediate portion therebetween. The self-adjusting pliers include a first pivot pin about which the first and second plier members pivot permitting the jaw portions to converge on a workpiece and grasp the workpiece in response to initial movement of the handle portions toward each other. The self adjusting pliers further include a second pivot pin about which the pliers pivot once pivoting has been terminated about the first pivot pin so as to permit a further grasping force to be applied to the workpiece in response to continued movement of the handle portions toward each other. The second pivot pin is closer to the jaw portions than the first pivot pin to allow for a greater mechanical advantage to be obtained. The self adjusting pliers also include a biasing spring for biasing the handle portions away from each other and the jaw portions away from each other.

Abstract: A medical item dispensing apparatus includes a dispenser (100) which encloses a plurality of magazines (168). Each magazine holds a plurality of medical items (170) which in the preferred form of the invention are cylindrical containers. Each magazine includes an opening (180). A guide (182) and a front gate member (194) are positioned adjacent to the opening. A back gate member (200) is positioned further inward from the opening than the front gate member. The front gate member and back gate member are moved in coordinated relation so that the front gate member enables a medical item adjacent the opening to pass through the opening while the back gate member moves to prevent the other medical items in the magazine from moving toward the opening. After the dispense of the medical item from the magazine the front gate member moves to block the passage of further medical items through the opening while the back gate member moves to enable medical items to move toward the opening.

Abstract: The invention includes pliers with self-adjustment capability for applying an initial grasping force to a workpiece and for augmenting the initial grasping force applied to the workpiece. The pliers are structured such that angular displacement of a handle portion of a first plier member is smaller than angular displacement of a jaw portion of the first plier member during an initial movement of the handle portions toward each other for applying the initial grasping force to the workpiece. In addition, the pliers are structured such that angular displacement of the handle portion of the first plier member is larger than angular displacement of the jaw portion of the first plier member to permit augmenting of the initial grasping force applied to the workpiece during a continued movement of the handle portions toward each other.

Abstract: A system for monitoring and dispensing medical items includes a plurality of hook registers (10). Each of the hook registers includes sensors (48, 60, 62, 64) sensing the removal or addition of a medical item to the storage location on the hook register. Each hook register has a microprocessor (66) connected to the sensor which stores a count of the items added or removed from the location. The microprocessor also includes location identifying information specifically associated with the particular hook register. The microprocessor is periodically polled by a controller (72) which reads and stores the count and location identifying information from each of the hook registers. The controller information is periodically read by a data terminal (76) which is connected through a local area network (82) to a remote computer (84) having a processor and data store.

Abstract: Inventory monitoring apparatus capable of real-time counting of objects added to or subtracted from a location whose inventory is to be monitored. The apparatus includes structure for supporting a plurality of objects and at least one lever adapted to be contacted and displaced by movement of the objects to and from the supporting structure. Movement of the lever in one direction triggers a switch which generates a signal indicating that an object is being added to the support structure. Similarly, opposite movement of the lever triggers another switch which generates a signal indicating that an object is being removed from the support structure. A microprocessor receives and counts the signals generated by the switches to provide a real-time total of the quantity and, if desired, the locations of objects borne by the supporting structure.
