An ambulatory infusion and/or KVO (keep vein open) system (12, 18) has a gas-pressurized bladder arrangement (12) including a gas barrier associated therewith. The system includes a flexible bag of solution (13) inserted in a sleeve portion (36) of the bladder arrangement (12). Internal gas pressure which is developed within the bladder arrangement by a selectively initiated chemical reaction exerts a continuing pressure against the solution bag (13) to cause the solution to flow therefrom. A tubing set (18) of the system includes a flow restrictor (24) which is sized for minimal flow rates for indwelling catheter patency maintenance.

A system for inspecting and sorting molded containers, such as glass bottles that includes a finished product inspection station for inspecting containers transported in sequence along a predetermined path, identifying containers to be sorted from the path on the basis of container mold of origin, and providing an electrical signal indicative of such containers. A conveyor is disposed adjacent to the container path downstream of the finished product inspection station, and is responsive to an electronic control signal for selectively removing a container from the path as the container passes adjacent to the conveyor. A timer receives the electrical signal from the inspection station, and applies the electronic control signal to the conveyor after a time delay coordinated with distance between the inspection station and the conveyor, and velocity of travel of containers along the path between the inspection station and the conveyor.

A selectible computer tape drive activation and deactivation technique apparatus is disclosed. The invention integrates with existing floppy controllers in a manner which allows activation and deactivation of a computer tape drive without the need for select lines. The invention programs the floppy controller so as to generate an activation command which may be appended by an address to specify the specific drive involved. Both the command and the argument are chosen to be consistent with existing Quarter Inch Committee standards. With respect to the deselect method, additionally a failsafe, independent deactivation path exists to turn off the tape drive in the event any conflict in drive operations were to exist.

A cap assembly is provided for mounting over the mouth of a container which is occluded with a stopper. The cap assembly includes a housing, a moveable piercing member or penetrator within the housing, a removable overcap over the housing, and a ferrule connecting the housing to the container. A preferred form of the penetrator is fabricated from sheet metal in a progressive die stamping process. One form of the overcap includes a frangible construction that permits the upper part of the overcap to be torn away to expose the upper portion of the housing.
摘要:
A flow restrictive edge profile applied to a fluid propelled/propelling implement and for creating increased driving force as a blade interacts with a fluid medium. An arcuate blade face pattern, including such as a “horseshoe” or modified “U” shape profile, is applied to one or two opposite faces of an oar design, with a deepened and inner extending connecting (arcuate) edge establishing a maximum of resistance (and a corresponding minimization of fluid losses) when traveling through the fluid medium. This in turn maximizes the amount of driving efficiency (e.g. thrust) to the article, such as during it being physically translated through a water medium or acted upon by a wind stream medium. The flow restrictive edge profile also contemplates application into one more blades associated with such as a rotating propeller or a driven windmill.

A tape drive control system with improved overall dam transfer rate. A streaming tape drive system for a multi-track serpentine data tape is controlled by a host computer. The data tape has a fixed number of data sectors per track. The host computer monitors tape position by observing data sector identification. The drive sends a ready/not-ready status signal to the host. The drive has a default mode. In the default mode, the drive generates an error signal if the host sends motor speed commands or head movement commands when the drive is sending a not-ready status. The host computer software can command the drive to enter a special mode. In the special mode, the drive does not generate an error if the host sends motor speed commands or head movement commands when the drive is sending a not-ready status. After placing the drive in the special mode, when the end of data for a track is reached, the host computer ignores the drive status signal and commands the tape drive to immediately set its motor to the maximum speed and to immediately move the head to the next track.
摘要:
A penetrator for penetrating a stopper sealing an opening in a container. The penetrator includes a stamped piece of sheet material formed to define a shank having a length. A groove extends along the length of the shank. The shank has a pointed distal. The stamped piece of sheet material further includes a bearing plate extending from the shank at a proximal end opposite the distal end of the shank.

A closure is provided for mounting across the mouth of a container and through which liquid can be withdrawn with a fluid transfer device having a male member. The closure includes a body for being disposed on the container across the container mouth. The body defines a passage with an exterior opening for matingly receiving the male member of the fluid transfer device. A frangible seal initially extends across the passage in the body to occlude the passage. The seal is broken when it is engaged by the male member of the fluid transfer device, thereby establishing fluid communication between the fluid transfer device and the interior of the container.

A cap assembly for a container has a hollow housing with an upper end that receives a fluid transfer device and a lower end that engages a stopper on the container. The housing has an internal cavity open at the upper and lower ends and a radially outwardly extending portion at the lower end. A penetrator is received in the internal cavity. The penetrator has a pointed distal end opposite the stopper and an upper end constructed to be engaged by a fluid transfer device. A cap is constructed the hollow housing. The cap has a closed upper end, an open lower end, a radially outwardly extending portion at the open end, and a circumferential line of weakness connecting the upper and lower ends. A ferrule is over the radially outwardly extending portion of the hollow housing and the radially outwardly extending portion of the cap.
