Abstract: The present invention relates to a process for making and a method for using a corrosion inhibitor composition to reduce the corrosion rate of a metal by a fluid containing a corrosion agent. The corrosion inhibitor composition comprises at least a quaternized compound having an amido moiety. An example of the quaternized compound is a quaternized amido imidazoline.

Abstract: A process and apparatus are provided for assembling two, mating, threaded containers. The threaded end of the first container is disposed in the threaded port of the second container. The second container is clamped to prevent rotation of the second container. A cam is rotated to engage a torque-applying assembly to produce relative movement between the clamp assembly and the torque-applying assembly. This effects sequential engagement and disengagement of the torque-applying assembly and the first container. The torque-applying assembly is rotated relative to the clamp assembly while engaged with the first container to effect threaded engagement of the containers.

Abstract: A coronary sinus catheter introducer system in which an introducer is installed in the right atrium of the cardiovascular system of a patient for delivery of a coronary sinus catheter into the coronary sinus. A bend near the distal end of the introducer enables placement of the end of the introducer into the coronary sinus opening and within the coronary sinus. A soft pliable tip end provided on the introducer minimizes abrasion of the coronary sinus and its opening by the introducer.

Abstract: A identification system for a cassette pump wherein a plurality of different types of cassettes administer different types of drugs, and each type of cassette is characterized by a different type determinative indicia carried by the cassette, and the cassette pump includes a prime mover for actuating the plurality of different types of cassettes corresponding number of different operating modes, each operating mode being used with a corresponding different type of cassette, wherein the pump-cassette interface for receiving and actuating each of the different types of cassettes includes a sensor disposed at the pump-cassette interface, and when the sensor is engaged by the type determinative indicia of a cassette, the pump is able to identify the particular type cassette inserted into the pump, and initiate the operating mode of the pump associated with the specific type of cassette positioned at the pump-cassette interface.

Abstract: A solution administration apparatus for patient care, for use with an associated solution administration system, which apparatus includes a laser drilled orifice flow control device to provide a controlled, predetermined flow rate of solution to the patient. The apparatus includes a tubing set and a laser drilled orifice flow restrictor, formed in a body, and in fluid communication therewith, for use with an associated fluid supply container. The system provides a controlled, predetermined flow rate of solution to the patient which is independent of, and relatively constant over minor variations in solution supply pressure and viscosity.
