PURPOSE:To enable manufacturing of lead storage batteries selected into two species of a high capacity type and a long life type by changing a ratio of the amount of paste, with which a non-formation anode plate is filled, to the amount of paste, with which a non-formation cathode plate is filled, so that phase composition in an active material at a formed cathode plate of post-formation is change...

PURPOSE:To improve the discharge property by using a substantially unfluidized electrolyte, polymerizing a synthetic resin fiber over the surfaces of a positive and a negative electrode plates in a biting condition, and laminating them each other through separators consisting of minute fibers to arrange parallel the electrode groups. CONSTITUTION:An electrode group 4 furnishes plural electrode pla...

PURPOSE:To make effective heat collecting operation possible by changing the capacity of a compressor in accordance with the signal of a setting means for heat collecting operation condition, the signal of a switchover means for compressor capacity, and the signal of a detecting circuit for the outside air temp. CONSTITUTION:A heat collecting circuit consists of a compressor 1, a fourway cock 2, a...

PURPOSE:To prevent the supplied hot water in a heat storage vessel from being stored with temp. distribution in accumulation regardless of the change in the outside air environment by a method wherein a high-low pressure bypass circuit equipped with a check valve and a pressure reducing device is connected in parallel to the expansion valve and heat collector of a main refrigerant circulation circ...

A method is disclosed for absorbing bases, acids, alcohols and radioactive liquids using phenol resin foamed plastic particles. The size of the particles should lie between about 0.3 and 3 mm. The particles are initially closed-celled, but have been powdered or fine flaked. They may be treated with an acid for absorbing a base, or with a base for absorbing an acid. A preferred use is in the form o...

This invention describes novel molded flexible polyurethane foam surfactants which can be used in foam having high concentrations of reinforcing graft copolymer solids. The invention also describes an improved process for making these foams using the novel surfactants.

Metallic sintered parts with hollow structure and high density and toughness can be produced easily by kneading a raw metallic powder with an aqueous solution of an organic binder, extruding the resulting kneaded mixture, removing the organic binder from the extruded product and sintering the binder removed extruded product.

The gas cooler has a pair of coaxial flues for the cooling of a synthesis gas wherein the flues are resiliently mounted independently of each other. The gas flow connection at the top of the pressure vessel is sized to permit the inner flue to be lifted out of the vessel for cleaning and repair purposes. In addition, the outer flue can be constructed of interconnected wall elements which may also ...

An improved hydrogel adhesive, particularly adapted for adhesion and contact to tissue. It is especially useful in attaching electrical leads to tissue, for example in attaching pacemaker leads to the heart, interiorly or exteriorly.

A drum brake comprises two brake shoes (4,5) which are operable hydraulically and/or mechanically. A first brake shoe (4) is supported trailingly in forward travelling direction and leadingly in backward travelling direction. In the forward travelling direction both brake shoes (4,5) are supported trailingly so as to obtain soft response behavior. And a lever (7) is supported at the second brake s...

The rate and ease of water dispersibility and/or water solubility of powdered or granular starch materials are substantially enhanced by the incorporation therein of a small but effective amount of a glycoside surfactant ingredient.

Free-flowing plural extrudates of a polar ethylene interpolymer, and method of preparing the same. The extrudates are essentially coated with about 0.001-2 percent, by weight of the composition, fumed silica, preferably about 0.025-0.05 weight percent. The fumed silica has an average primary particle size of about 5-25 millimicrons, a surface area of about 200-250 m2/g, and is substantially amorph...

The polymerization of compositions containing styrene by an aqueous suspension process in which is used a suspending agents system constituted by a mineral agent and, an extending agent which is at least a rosin acid derivative (abietic acid, neoabietic acid, dextropimaric acid) or their salts of a metal belonging to Group IIa of the Periodic Classification of elements. The use of this extending a...

Expanded particles obtained by a method including the steps of: providing unexpanded particles formed of a polyethylene resin; impregnating the unexpanded particles with a liquid containing a polymerizable monomer including an acrylic monomer, and optionally a styrenic monomer; subjecting the impregnated polymerizable monomer to polymerization conditions so that at least a portion of the polymeriz...
