Abstract: Vanadium compound/organometallic compound/inorganic oxid catalyst compositions useful for the polymerization of ethylene to polymers having a molecular weight distribution that can be controlled by selection of the appropriate member of a particular family of vanadium compounds are obtained by using, as the vanadium component, at least one vanadium compound prepared by reacting one molar proportion of VOCI<sub>3</sub> and/or VOBr<sub>3</sub> with about 0.5 to 1 molar proportion of a diol corresponding to the formula HO-R-OH, wherein R is a divalent hydrocarbon radical having a chain length of 2 to 16 carbon atoms. The molecular weight distributions of polymers formed in the presence of the catalyst compositions are narrowed as the cain length of R is increased. The preferred vanadium compounds are those prepared by reacting VOCI<sub>3</sub> with a diol wherein R is a straight- or branched-chain alkylene group containing 2 to 6 carbon atoms.

Abstract: An improved switch for a high-voltage device in which ignition of a power cartridge moves an insulative piston located in a conductive member away therefrom and into a passageway in an insulative liner. The piston moves a contact through the passageway and away from the conductive member to break an electrical interconnection between the conductive member and the movable contact, thereby opening the switch. The switch includes an insulative housing engageably surrounding, holding and fixing the relative positions of the conductive member and the liner. An interiorly relieved extension is formed at and about one end of the liner, and an exteriorly relieved region is formed in and about one end of the conductive member, whereby the region may be telescoped into and conformally engage the inside of the extension so that the conductive member and liner partially overlap along a tortuous interface so as to increase the interrupting capability of the switch by enhancing the isolation between the power cartridge and the passageway.

Abstract: An angiographic injector device for use in x-ray photography for delivering contrast media to a patient at controlled rates and pressures. A processor elicits injection parameters from an operator or a pre-programmed injection module, and on the basis of the injection parameters, calculates appropriate control signals for use in a closedloop servo system to actuate the plunger of a syringe containing the contrast media. Injection parameters include flow rate, volume, duration, pressure limit and rise/fall time of flow rate. The device also includes control circuits for inhibiting the injection device in response to a contrast media pressure limit, failure in the processor or injection control system, or upon reaching a predetermined volume of injected media. A mechanical stop member cooperates with the control circuit for blocking movement of the syringe plunger upon reaching the predetermined injected volume. Further, the device includes a self-test feature for checking the status of operational components thereof and a self-calibration feature for calibrating the servo system and position monitors. To improve reliability and to provide immunity from data corruption due to line power interruption, injection parameters are stored in battery-powered primary and secondary memories, and are compared and verified prior to an injection. To assist in coordinating an injection in synchronism with cardiac activity, the device monitors the ECG waveform of the patient's heart and injects a small bolus of contrast media at a given interval, such as the distolic interval. An interface also is provided for providing remote transfer of status and control information with the angiographic injector device.

Abstract: An implantable microprocessor-controlled dual chamber heart pacemaker is programmed to control the timing of the pacing of the ventricle in response to high rate atrial signals. The microprocessor operates in conjunction with an atrial timer to detect atrial signals which occur at a rate in excess of a predefined atrial rate limit. The microprocessor paces the ventricle at a predefined desirable demand rate and inhibits pacing of the atrium in response to the high rate atrial activity. The microprocessor also controls the timing of an atrial refractory interval which includes an absolute refractory portion during which atrial signals are not detected and a relative refractory portion during which atrial signals are detected but are not tracked. The combined absolute and relative atrial refractory portions insure that relatively high rate atrial signals are detected and spurious signals conducted from the ventricle are ignored.
