The plate (10) comprises a matrix or binder resin phase (12) in which is dispersed particulate, conductive tin oxide such as tin oxide coated glass fibers (14). A monopolar plate (11) is prepared by coating a layer (18) of electrolytically active material onto a surface of the plate (10). Tin oxide is prevented from reduction by coating a surface of the plate (10) with a conductive, impervious lay...

The unitary electrode (10) comprises a porous sheet (12) of fiberglass the strands (14) of which contain a coating (16) of conductive tin oxide. The lower portion of the sheet contains a layer (18) of resin and the upper layer (20) contains lead dioxide forming a positive active electrode on an electrolyte-impervious layer. The strands (14) form a continuous conduction path through both layers (16...

Chair support pivotably carries parallelogramic support arms which are pivoted to seat rails. One of the support arms continues above the seat rail to become an arm support and adjacent the top thereof carries one end of a telescoping unit. The other end of the telescoping unit is pivoted to the seat rail. The telescoping unit is of such length that, when the support arms are in the erected positi...

Metal flake of improved conductivity is produced by a method comprising wet ball milling a powder of a conductive metal in the presence of a lubricant comprising an organometallic compound.

A modified low-density flexible polyurethane foam product having a relatively high degree of firmness as well as commercially acceptable dielectric heat sealing characteristics. The product formulation includes an intermediate constituted by a mixture of polyol and a polymer/polyol in a ratio imparting to the product a predetermined degree of firmness, and a thermoplastic additive whose dielectric...

Haloalkoxymethylmelamine adduct is prepared by reacting hexamethoxymethylmelamine with a halogenated alcohol. Dispersions of this adduct in a polyol produce a polyurethane product which displays improved flame retardancy.

1,3-Pentadiene is polymerized in an inert gaseous atmosphere from a mixture of saturated and unsaturated hydrocarbon molecules. At least 50 percent by weight of said molecules have 5 carbon atoms. An anionic polymerization initiator in conjunction with an organic polar solvent is used to effect polymerization. Cyclopentadiene, active hydrogen compounds and other polymerization-terminating compound...

A casting or injection mold for vehicle tires comprises two separable half-shells together defining an annular cavity into which a segmented core is introduced, radially inwardly converging core segments alternating with parallel-sided or radially inwardly diverging core segments to facilitate extraction of the core from the molded tire. In operation, one or more of the non-converging segments are...

A safety toe clamp for a ski binding is disclosed wherein a ski boot sole holder is pivotally mounted for lateral movement on a body member provided with adjustable spring means urging said sole holder in a forward direction. Each of a pair of surfaces on said body member is each oppositely disposed outside of the central axis of the body member and adapted to cooperate with corresponding surfaces...

A false ceiling (10) includes a plurality of concave panels (12, 60) having liquid spray nozzles (40, 62) at their crowns. The liquid streams down the undersides of the panels to collecting channels (16) and carries with it particles of dirt, grease, etc., entrained in vapors from kitchen burners or the like below. Air is exhausted through the spaced openings between the edges (14) of the panels a...

The tire building machine comprises a tire building drum or shaper, annular bladders adjacent each end and a bead setter and bladder pusher mechanism movable axially of the drum selectively to set a tire bead in proper position and to push and effectively roll the bladder when inflated to cause the ply edges of the tire to be wrapped about the bead without air entrapment and stitched securely. Suc...

A switchable permanent magnet eddy current or track brake which has a high density of permanent magnet material, a low internal flux leakage and a higher than heretofore output flux density.
