摘要： A liquid sterilizing system (A) defines a basin (10) in which a container (B) is removably disposed. The liquid sterilizing system selectively pumps sterile rinse liquids from a supply (24) and liquid sterilant solutions from a supply (70) into the basin filling the basin and the container. The container includes a lower shell having a bottom wall (34) that defines an aperture (32) for receiving sterilant and sterile rinse liquids. A nozzle plate (44) is mounted close to but spaced from the shell bottom wall to define a tortuous liquid distribution path (40) between the inlet aperture and nozzle plate apertures (90). A barrier (96) divides the liquid receiving portion and a drain portion of the liquid distribution path between the shell bottom surface and the nozzle plate. A cover (80) has a downward depending peripheral wall (82) which is offset from the shell peripheral wall (86) by the spacers (88) to define a tortuous vent path (48) therethrough. The container is lifted out by handles (100) which enable the container to be removed without disturbing the transparent cover, hence, without disturbing the sterile condition of the items within the container. In this manner, the sterilized items can be inventoried and maintained sterilized in the container for an extended duration.

摘要： Each of a plurality of modules (A) have fitings (14) with automatically closed check valves (16) therein such that the interior of the module is sealed. The module is selectively interconnected with a sterilizer apparatus (B). Interconnecting tubing (60) selectively supplied liquid from a reservoir (30) to the module. A sterilant injection chamber (56) receives and punctures a sterilant ampule such that incoming water mixes with the sterilant concentrate forming a sterilant solution which is carried to the reservoir. A reservoir outlet valve (70) selectively permits the sterilant solution to pass from the reservoir through the interconnecting tubing into the module until the module and interconnecting tubing are completely filled. Thereafter, the reservoir outlet valve closes holding the sterilant in the interconnecting tubing as well as the module for sufficient duration to sterilize both. Concurrently, additional tap water is heated in the reservoir until it is sterile. Alternate means of sterilizing the rinse fluid may also be employed. Thereafter, the reservoir outlet valve is opened again and the sterilant solution is drained and rinsed from the module with the sterile water. An air pump (86), a heater (84), and a submicron sterilization filter (82) supply heated, sterile drying air through the reservoir, connecting tubing, and module to dry the sterilized device.

摘要： A tubing system (18) connects a source (10) of tap water with a container (20) holding an item to be sterilized. Powdered buffers, detergents, and corrosion inhibitors are deposited in a well (34) along with an ampule (46) containing a sterilant, such as peracetic acid. The ampule includes an exterior wall (80) which defines an interior volume (82) and a linear vent passage (84) extending from the exterior wall to a central region of the interior volume. A gas permeable liquid impermeable membrane (100) is mounted across a vent aperture (86) which is disposed adjacent the geometric center of the interior volume. The volume is filled less than half way full with the liquid sterilant such that in all orientations of the ampule (FIGS. 4A-C), an upper surface (98) of the sterilant remains below the vent aperture. A pump (50) recirculates the water through the container, the tubing system, and the well to dissolve the powdered reagents. A tubular needle (70) of an aspirator system (42) is moved along the vent passage and through the vent aperture such that its free end is immersed in the sterilant. An aspirator (44) draws the sterilant from the ampule into the tubing system, mixing it with the recirculating water.

摘要： A housing (10, 46, 64, 90, 100) has an internal opening in which a thin recess is defined for receiving a heat expansible polymer (30) and a heating element (24). In some embodiments, an insert (14, 98, 102) is inserted into the housing bore such that the thin recess is defined therebetween. In other embodiments, the recess is defined between the housing and a force receiving surface of a piston (40, 60). When the heating element is heated, the polymer expands, forcing the piston to extend. When heating is stopped, the polymer cools allowing the piston to retract. In the embodiment of FIG. 4, the retraction is accelerated by a second polymer and heating element region (54). In other embodiments, a transmission arrangement (72, 74, 78; 124, 126, 128) is provided for converting the relatively high force, low travel of the heated polymer to a higher travel lower force output. In one embodiment, the heating element is resistance heating wire (32) which is surrounded by a covering (36) of electrically insulating material which is porous to the melted polymer.

摘要： A piston (14) is slidably received in a chamber (10). The chamber is filled with an expandable medium (16), such as wax, that expands and contracts significantly as it undergoes a phase change from a solid to a liquid state. A Peltier effect chip (20) selectively adds and removes heat energy from the chamber, hence the medium, to cause the medium to change phase. A temperature control (26) maintains the temperature of the medium substantially at the phase change temperature such that the addition of heat causes an isothermal melting (hence, expansion) and the removal of heat causes an isothermal solidification (hence, contraction). The chamber defines a plurality of thin branches (42) such that the heat is transferred more effectively.

摘要： A workpiece is held between a movable clamping element (56) and a stationary clamping element (52). During setup, a hex drive (58) is rotated to move a traveler (100) which is connected to the movable clamping element along a threaded shaft (80). The threaded shaft is supported at one end through a spring retainer nut (88), a spring (86), and a bearing (82). After the movable clamping element engages the workpiece, the spring is compressed, limiting the amount of clamping force applied to the workpiece. The retainer nut (88) is selectively moved through the use of the tool to a selectable position along the threaded shaft (80) to adjust the spring compression, hence the clamping force. After initial setup, an electrochemical actuator (110) is actuated to melt a polymer, forcing a piston assembly (118, 120) and a bearing (84) to shift the threaded shaft (80) longitudinally against the spring, moving the clamping elements apart a short distance to release or receive a workpiece. The electrochemical actuator is then deactivated, allowing the spring to expand, clamping the workpiece between the clamping elements with the selected force. This enables an operator to load a workpiece manually into a vise (12) at a loading station (14). An automatic controller (30) controls a plurality of the vises, a moving table (10), a plurality of machine tools (18), and optionally, a robotic workpiece repositioning station (20).

摘要： A clamping device includes an expansible polymer that is disposed in a polymer chamber (14). A heat transfer conduit (22) transports heat transfer fluid and brings it into thermal conductivity with the polymer. By cooling or heating the polymer as needed, the polymer expands and contracts as it melts and freezes, respectively. The volume change of the polymer is used to advance a piston (16). The piston is used to engage upon a surface, e.g., clamp a machine part. In this manner, the surface is disposed between the actuated piston (16) and an immobile plate, causing the surface to become rigidly held in position. When the piston (16) contacts the surface, pressure builds in the polymer chamber(14), which translates into clamping force on the surface.

摘要： An actuator (A) includes a body (10) in which a plurality of chambers or bores (34) are defined. The bores are interconnected at an inner end by an elongated passage (30). A heater element (32) extends along the elongated passage. The elongated passage and the inner portion of each chamber or bore are filled with a polymeric material which expands and flows on heating, preferably undergoing a solid to liquid phase change. Extensible members (12), such as pistons, diaphragms, bellows, or the like, are mounted in the bores or wells. When the heater heats the polymeric material causing it to expand and flow, the extensible elements (12) extend under high force with limited travel. In one embodiment, the extension of the extensible members moves a thrust bearing (B) causing frictionally engageable plates (18, 22) of a friction member assembly (C) to engage.

摘要： An operator selects an operating characteristic, such as a degree of extension or force of an extension member (66) of a thermal actuator (16), with an input circuit (10). The input control circuit generates a reference signal. A feedback circuit (18) monitors a characteristic of the thermal actuator such as a temperature of its internal polymer, extension of the extension member, force, or the like, and generates a corresponding feedback signal. An error circuit (12) compares the reference and feedback signals and generates an error signal in accordance therewith. A dither circuit (30) generates an oscillating dither signal that is superimposed on one of the control and feedback signals before comparison by the error circuit. A power conversion circuit (14) adjusts an amount of electrical power supplied to a heating element (54) of the thermal actuator in accordance with the error signal.
