Abstract:
A lantern assembly (10) is provided having a handle supporting beam. The handle (18) is attached to a low profile base (16) containing a channel (80) defined about its circumference configured to receive and stow a length of electric cord (82) therein. The electric cord (82) is connected at one end to a pair of terminals (84) extending from the top of the base (16), which also serves to attach the handle (18) to the base (16). The opposite end of the electric cord (82) is attached to a connector (90) for coupling the lamp to the vehicle power supply. The lamp configuration is specially configured and adapted to easily convert a battery-powered lantern to one for use with a vehicle.
Abstract:
An electrochemical cell having a zinc anode comprising zinc flakes or zinc alloy flakes. Various mixtures comprising zinc flakes having a high average surface area (compared to typical powders) are disclosed.
Abstract:
A galvanic cell, especially a miniature galvanic cell, comprises a cupped container, a cover therefor, and a gasket, the cover having a depending flange, the gasket being compressed between the container and the flange of the cover such as to seal the cell and to electrically insulate the cover from the container, wherein the flange extends no further than half of the way into the container from the rim of the container and allows the gasket component to occupy less than 8 % of the internal volume of the cell, thereby allowing more room for active components.
Abstract:
An electrochemical cell (2) having an alkaline electrolyte, a cathode comprised of a metal oxide (6) and a zinc anode (10) wherein the anode current collector (22) of the cell is made of the same zinc material as that which forms the anode active material.
Abstract:
The invention relates to a housing which receives dry cells in an in-line or end to end orientation. The invention includes features which prevent the incorrect orientation by preventing dry cell terminals making contact with the necessary components. In this way it prevents premature dissipation of dry cells or their impairment. The mechanism by which these features do this is to recess one terminal namely that terminal which would be contacted by the positive terminal of a dry cell. In this way the negative terminal of a dry cell can never make electrical connection. Another feature of the invention is the provision of an aperture having a profile of a silhouette of a dry cell, which has advantages in low light situations, saves material, and allows for relatively easy extraction of dry cells from the cartridge.
Abstract:
The present invention relates to a circuit for a portable lighting product such as flashlight, lantern, desk lamp, area light, combination area light and flashlight, front and rear bicycle light, emergency light, night light, rechargeable versions of any of those products previously mentioned, in which several power sources are provided. The invention includes the feature that each power source is electrically isolated from each other by the switch in mechanism or mechanisms, when the portable lighting product is switched to the off condition. The power sources can include single dry cells, or sets of series connected dry cells of any number.
Abstract:
A gasket-cover assembly for use as a closure for an electrochemical cell which is produced by a process in which an extended wall (16) of the cover (8) is ultrasonically forced into a flange (6) of a gasket (4) such that the flange of the gasket makes a "U" shaped enclosure about the bottom wall of the cover.
Abstract:
A label that can be applied to an arcuate surface of an article such as to the exterior surface of a cylindrical dry cell battery which includes a bottom layer and an outer layer. The bottom layer (3) can be positioned adjacent to the arcuate surface and is adherable thereto. The bottom layer includes at least one opening (4). The opening is bounded by a first edge (12), and a second edge (13). The second edge (13) extends generally parallel to the first edge (12). The outer layer (9) is operatively connected to the bottom layer at a first and a second location. The opening is positioned on a portion of the bottom layer between the first and second locations. Whereby the first and second locations are moved into a closer relative position by tension created by the outer layer (9), however the opening prevents buckling of the bottom layer.
Abstract:
A battery core winding apparatus for winding into an electrochemical cell, a plurality of flexible strip members comprising a first conducting flexible electrode (86) having a first leading edge (87), a second conducting flexible electrode (88) having a second leading edge (89), and a separator (90), includes a first elongate feeder bed and a second elongate feeder bed longitudinally disposed from the first feeder bed. A winding cavity is formed between the feeder beds. A first arbor half (58) having a first flat surface and a first curvilinear winding surface is rotatingly supported within the winding cavity substantially midway between the first and second feeder beds, and a second arbor half (64) having a second flat surface and a second curvilinear winding surface is rotatingly supported within the winding cavity such that the second flat surface faces the first flat surface and the first and second flat surfaces are interspaced to form a slot. A first pair of forming rollers (48, 50) are rotatingly supported and disposed within the winding cavity proximate to and forming a gap with the first curvilinear surface and a second pair of forming rollers (54, 56) are disposed within the winding cavity proximate to and forming a gap with the second curvilinear surface. At least one feeder roller (32) is rotatingly embedded in each of the first and second feeder beds, the rotational axis of each roller being substantially perpendicular to the elongate axis of the feeder beds, and a pressure roller (34) is rotatingly mounted in registration with each of the feeder rollers, the pressure roller axis of rotation being parallel to that of the feeder roller and each pressure roller is spring biased against its adjacent feeder roller.
Abstract:
A portable lighting device (such as a bicycle lamp) may include the following: an arrangement (illustrated) of light emitting diodes (38, 40, 42) at different angles to each other so that light can travel in at least two directions away from the lighting device; use of multiple images of at least one light emitting diode to present a more visible effect from one or more light emitting diodes; a body portion which will glow when internally generated light falls upon it; a main lamp and openings or channelling means so that light is also emitted from side portions; faired surfaces to facilitate the use of the lighting device in more than one situation; or a lens section having at least two side portions in optical communication with a light emitting diode.
