An asymmetric split bearing with a geometrically contoured work surface is provided that has an upper segment and lower segment and a plurality of spaced, recesses in the sidewall of the bearing segment, which are joined together by means of bearing surfaces or lands. The asymmetric split bearing allows for a greater range of applications, such as reciprocating engine crankshafts, which require split bearings for support. The number of bearing surfaces on each segment can be optimized for load conditions and to minimize friction. The bearing utilizes powdered metal manufacturing and is self-cleaning.

A laryngoscope constructed of materials including metal components having very low magnetic susceptibilities is described. The battery powering the laryngoscope lamp is a lithium battery also constructed of materials having low magnetic susceptibilities. The battery further includes a unique terminal configuration that prevents the inadvertent use of other batteries, including non-magnetic batteries, in the laryngoscope. A unique lamp retaining mechanism provides for quick and easy replacement of the lamp.

A penlight constructed of materials including metal components having very low magnetic susceptibilities is described. The battery powering the penlight lamp is a lithium battery also constructed of materials having low magnetic susceptibilities. The penlight is particularly useful in the vicinity of the strong magnetic field of an MRI scanner.

A perforated fabric for modifying the effective electrochemical surface area of a cell is described. The size and pattern of perforations in the fabric determine the effective electrochemical surface area of the cell. In practice, the modified cell comprises a layer of perforated fabric placed between the anode and the cathode along with a suitable electrolyte absorbent separator material. Electrodes are then assembled into a cell using typical techniques with a spirally-wound configuration being preferred. The present perforated fabric provides for the production of cells with variable effective electrochemical surface areas while using a single manufacturing line. A preferred cell chemistry comprises a fluorinated carbon electrode present in an alkali metal system with the preferred perforated fabric comprising a Fluorpeel fabric, which is a woven fiberglass cloth impregnated with PTFE polymer.

A spirally-wound electrochemical cell having a resilient member such as a resilient pad or a wave spring disposed between the spirally-wound electrode and separator assembly and at least one of the end walls for resiliently dissipating mechanical forces acting to otherwise cause axial movements of the spirally-wound assembly.

A method for preparing an electrode component comprises mixing an electrode active material in a water-based environment with the aid of surfactants. A preferred embodiment of this process comprises combining a high surface area carbonaceous cathode active material with a water/surfactant mixture, and then adding a fluoro-polymer as the binder material to the slurry. The resulting paste is processed and formed into the cathode material. This process replaces the use of isopropyl alcohol with the water/surfactant mixture as the solvent. Preferred surfactants include those of the polyglycol family.

A structure for stabilizing of an electrochemical cell stack against high shock and vibration forces through the use of a plurality of electrode connections at both the top and bottom of the stack is described. Constructing the cell casing having a tubular shape rather than the typical deep drawn can shape, allows access to the lower portion of the stack. There, additional leads are welded to the cell case, which significantly adds to the stability of the stack within the case. The lower portion of the case is then within the case. The lower portion of the case is then hermetically sealed by fitting and welding a disc in place.

Electrochemical cell design for use under high shock and vibration

A method for manufacturing electrochemical cells having a low electrochemical surface, from standard electrodes used in cells having a high electrochemical surface, includes configuring the standard electrodes by folding one or more of the standard electrodes to reduce the overall length, and hence the electrochemical surface area to a fraction of that of the unfolded standard electrode. A cell stack is assembled by placing the folded electrode and a standard electrode, or alternatively a folded cathode and a folded anode, in a face-to-face relationship with a separator therebetween.

Use of standard uniform electrode components in cells of either high or

A fabric separator woven from synthetic halogenated polymeric fibers for use in an electrochemical cell comprising a Group IA, IIA and IIIB metal anode and a depolarizer/catholyte or a solid cathode/electrolyte system, is described. The separator is resistant to the highly oxidizing components present in the cell, is tear resistant and has a reduced thickness to minimize the diminishing effect of the separator on the volumetric amount of active components in the cell. The separator can be used by itself or as a laminate with a microporous film, preferably made of a fluoropolymeric fiber.
