    Abstract: An electromagnetic pump comprising a housing having a fluid receiving chamber (14) in communication with an inlet (18), a fluid pumping chamber (16) in fluid communication with an outlet (20), a check valve operatively associated with the fluid receiving chamber, and a barrier in the form of a thin diaphragm hermetically isolating the electromagnet from the fluid chambers. An armature of the pump includes both a pole portion located for magnetic attraction by the electromagnet and a piston portion to force fluid out of the chambers. The armature pole portion has a fluid-contacting section of material which is compatible with and corrosion resistant to the fluid. A controlled bypass (274) is provided for bubbles in the fluid. An outlet orifice (290) and accumulator (436) are provided in the path of fluid flow from the pump outlet.

    Abstract: A new process for manufacturing a cathode component from a free-standing sheet of cathode material, is described. The process comprises a first step of adjusting the particle size of the cathode active material (42) to a useful size followed by mixing with a binder and conductive additives suspended in a solvent to form a paste (44). The paste is then fed into a series of roll mills (48) to form the sheet material or the paste can first be pelletized before the rolling step (46). The cathode sheet material is dried (52) and punched (56) into cathode plates having a myriad of geometric shapes suitable for cathode preparation by compressing a current collector between two plates of the cathode material (62).

    Abstract: An electromagnetic valve (10) comprising a housing (12) having a fluid containing region (14) and first and second ports (18, 20) in communication with the region (14), an electromagnet (130) carried by the housing (12) located external to the fluid containing region (14), of the housing (12), and a barrier in the form of a thin diaphragm (160) of fluid impermeable material which hermetically isolates the electromagnet (130) from the fluid containing region (14). An armature (200) is movably positioned in the region (14) and has a pole portion (204) located for magnetic attraction by the electromagnet (130) and has a plunger portion (202) provided with a valve formation (250) for opening and closing one of the ports (18, 20) to place both ports (18, 20) in fluid communication through the fluid containing region (14) of the housing (12) in one control state of the valve (10) and to block fluid communication between the ports (18, 20) in another control state of the valve (10). The armature (200) is moved from a rest position through a forward stroke when attracted by the electromagnet (130) to change the control state of the valve (10), and the armature (200) is moved by a biasing spring (244) in an opposite direction through a return stroke back to a rest position.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for improving application of a biomimetic surfactant to prevent blood coagulation on the surface of implantable medical equipment. SOLUTION: A method for providing a biomimetic coating on a substrate surface includes (a) preparing a substrate with a surface to be coated, (b) preparing the biomimetic surfactant, (c) mixing the biomimetic surfactant in a solvent mixture comprising water and an organic water miscible solvent, thereby creating a biomimetic surfactant solution, and (d) applying the biomimetic surfactant solution to the substrate surface. The organic water miscible solvent drives the biomimetic surfactant out of the solution onto the substrate surface to create a coating of the biomimetic surfactant, thereby providing a method for improving the biomimetic surfactant coating to the substrate surface. A preferable biomimetic material is poly(N-vinyl hexyl amine-co-N-vinyl heparinamine-co-N-vinyl maltonoamide) or the like. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic interference (EMI) tank filter assembly. SOLUTION: This tank filter is provided for a lead wire of an active medical device (AMD). This tank filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the tank filter is resonant at a selected frequency. A passageway through the tank filter permits selective slidable passage of a guide wire therethrough for locating the lead wire in an implantable position. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the tank filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the tank filter is integrated into a TIP and/or RING electrode for an active implantable medical device. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To describe an improved formation electrolyte and a method for anodizing valve metal anodes used in electrolytic capacitors, particularly for high voltage sintered tantalum powder anode.
    SOLUTION: The anodizing electrolyte composition is comprised of (1) a phosphorous oxyacid and/or its salt, such as phosphoric acid and ammonium phosphate; (2) a weak inorganic acid/salt (such as boric acid, ammonium borate) or a weak carboxylic acid/salt; (3) water; and (4) a protic solvent or a mixture of two or more protic solvents. The weak mono-carboxylic acid/salt has 2 to 7 carbon atoms and the weak di-or poly-carboxylic acid/salt has 3 to 13 carbon atoms. The present electrolytes have high anodizing breakdown voltage capability and the formed dielectric oxides have improved oxide quality including good oxide hydration resistant ability, and result in more stable capacitor performance. These properties are particularly important for critical applications such as implantable cardioverter defibrillators (ICDs). Significantly, this means that fewer capacitors are needed to meet an ICD's operating voltage.
