  • Patent number: 11735711
    Abstract: A battery includes a case having a feedthrough port, a feedthrough assembly disposed in the feedthrough port, and a cell stack disposed within the case. The feedthrough port includes an inner conductor and an insulator core separating the inner conductor from the case. The cell stack includes an anode, a cathode, and a separator insulating the anode from the cathode, wherein the anode and cathode are offset from one another. An insulating boot surrounding the cell stack insulates the cell stack from the case. The insulating boot has an opening configured to receive therein the feedthrough assembly, which may include overmolded insulation. The interior surfaces and interior walls of the battery case may be thermal spray-coated with a dielectric material to prevent lithium dendrite formation between cathode and anode surfaces.

  • Publication number: 20210159470
    Abstract: The battery has a header positioned in an opening in a case. An electrode is in the case and a terminal is in electrical communication with the electrode through the header. A cured epoxy contacts the case and the terminal such that the epoxy seals the opening in the case. The header is located between the electrodes and the epoxy. The header can exclude a glass-to-metal seal.

  • Publication number: 20120141511
    Abstract: A novel agent for the targeted control of a mammalian cell activity can be used to control the interaction of particular cell types with their external environment. The agent has applications as a pharmaceutical for the treatment of a variety of disorders. An agent according to the invention comprises three Domains B, T and E, linked together in the following manner: Domain B-Domain T-Domain E where Domain B is the Binding Domain, which binds the agent to a Binding Site on the cell which undergoes endocytosis to produce an endosome; Domain T is the Translocation Domain, which translocates the agent from within the endosome across the endosomal membrane into the cytosol of the cell; and Domain E is the Effector Domain, which inhibits the ability of the Recyclable Membrane Vesicles to transport the Integral Membrane Proteins to the surface of the cell.

  • Patent number: 7611805
    Abstract: An electrochemical cell comprising a cathode of a powder material pressed into intimate contact with a rod-shaped current collector and an anode at least partially wrapped around the cathode is described. The cathode current collector is preferably provided with a plurality of offset flats offset with respect to each other. This helps prevent the cathode active material from sliding off of the rod-shaped current collector. The anode has spaced apart edges at opposite ends of its width that form a gap with the anode wrapped around the cathode. This helps in sliding the anode/cathode electrode assembly into a cylindrical tube comprising the cell casing. A preferred chemistry is a lithium/CFx activated with a nonaqueous electrolyte.

  • Patent number: 7452543
    Abstract: A class of novel agents that are able to modify nociceptive afferent function is provided. The agents may inhibit the release of neurotransmitters from discrete populations of neurones and thereby reduce or preferably prevent the transmission of afferent pain signals from peripheral to central pain fibers. They comprise a galactose-binding lectin linked to a derivative of a clostridial neurotoxin. The derivative of the clostridial neurotoxin comprises the L-chain, or a fragment thereof, which includes the active proteolytic enzyme domain of the light (L) chain, linked to a molecule or domain with membrane translocating activity. The agents may be used in or as pharmaceuticals for the treatment of pain, particular chronic pain.

  • Patent number: 7388463
    Abstract: An electromagnetic coil assembly comprising a spool-spindle and a case. The spool-spindle comprises a spindle portion and a larger included portion. The spindle portion has a conductor wound thereon. The larger included portion has opening for receiving the conductor. The case has a first case end and a second case end, with an opening extending through the case. A first internal surrounding surface extends from the second case end and a second surrounding internal surface having a smaller diameter extends from the first case end. The first internal surrounding surface meets the second internal surrounding surface at an annular internal wall. The spool-spindle is positioned in the case until the larger include portion abuts against the annular internal wall, and the case and spool-spindle are joined.
