  • Patent number: 5937552
    Abstract: An iron having a soleplate with a soleplate base and a soleplate wrap. The base is a unitary metal member with a heating element therein. The wrap is a one-piece sheet metal member that is directly attached onto the base.
    Type: Grant

    Inventor: Stephen M Hall
  • Patent number: 5924225
    Abstract: An iron having a housing with a skirt, a soleplate, and a heating element in the soleplate. The skirt has a molded body comprised of dielectric material. The body has a downwardly extending perimeter rim. A metal plating is adhered directly onto the rim to give an appearance of a metal skirt. The rim includes a base coat, the metal layer and a top coat. The base and top coats on the skirt being baked at particular temperatures and for particular amounts of time for curing and drying.

  • Patent number: 5922228
    Abstract: An iron is provided with heat buffering spacers which vertically set apart component elements in a stacked arrangement. The spacers cause gaps between stacked parts thus allowing for improved air convection through the iron as well as spacing the metallic heated elements from the thermoplastic elements which attach to it to prevent melting.

  • Patent number: 4519019
    Abstract: A ceiling light fitting has three extended, constant-section reflectors which are parallel to the wall, the reflector being swingable back to enable the lamp to be changed. The lamp filament is linear and parallel to the wall. The reflectors are of part-circular section and enhance the light, as well as the reflector acting as a mask to prevent the filament being seen from behind the fitting. The reflector projects very little below ceiling level. The reflector is parabolic with the filament at its focus, the axis of the parabola being directed at the base portion of the wall. The reflector faces downwards and has at least its major part above the level of the filament and on the wall side of the filament.

  • Patent number: 4474652
    Abstract: The present invention relates to an electrochemical process for synthesizing carboxylic acids by reduction of gaseous oxides of carbon in which a gas transfer electrode is used as the cathode.The gas transfer electrodes are preferably used as hydrophobic gas transfer electrodes. In carrying out the process it is particularly preferred to use porous, hydrophobic gas transfer electrodes made from an electrocatalyst e.g. carbon, bound in a polymer such as polyethylene or polytetrafluoroethylene (PTFE). In the case of some reactions another electro-catalyst may be added to the carbon/polymer mixture.The process is particularly suited to producing acids such as formic acid and oxalic acid.

  • Patent number: 4342792
    Abstract: This invention relates to novel electrodes and a method of preparation thereof for use in electrochemical cells. The novel electrodes contain a combination of electrocatalysts deposited on a metal substrate.The electrocatalysts are deposited from a homogeneous solution of the compounds of (a) at least one metal selected from iron, cobalt, manganese and nickel, (b) at least one metal selected from molybdenum, vanadium and tungsten, and (c) at least one rare earth metal of the lanthanide group having an atomic number of 57-71 inclusive, the metal compounds are decomposed to the oxides and the oxide coated substrate cured at elevated temperature in a reducing atmosphere. The electrodes thus produced can be used as an anode or as a cathode in fuel cells and in cells for the electrolysis of water or brines.
