PURPOSE:To enhance the cycle life characteristic of a pasted electrode plate for a lead storage battery by maintaining its rapid-discharge characteristic by pressing only the upper and the lower parts of the electrode plate except the central non-pressed part after the electrode plate is prepared by applying a lead paste to a grid, and solidifying thus treated electrode plate by drying. CONSTIT...

PURPOSE:To enhance the cycle life of a pasted electrode plate for a lead battery by suppressing the reduction of the initial characteristic of the electrode plate by pressing the lower part of the electrode plate while absorbing water from said lower part after the electrode plate is prepared by applying a lead paste to a grid, and solidifying thus treated electrode plate by drying. CONSTITUTION...

An accumulator with plate element of positive and negative electrode plates with interposed separators, lugs on the electrode plates interconnected by connecting straps, and at least one rib secured on the top surface of the plate and separator to secure the plate element to end walls. This enhances the capability of the accumulator to withstand vibration, i.e. makes it shake-resistant.

The appts. is partic. intended to utilise low speed winds, and is of the type which comprises a rotor having a number of blades adapted to rotate about a parallel axis to the direction of the windflow. The blades are shaped and arranged to form an annular ring of blades bound externally by a tubular element and internally by a tapered element effective to duct the air impinging thereon toward said...

The package includes leads extending from the circuit device to selected positions for interconnection both inside and outside the volume of the package such as for switch points or attachment of other electrical components to th...

A process for obtaining isobutylene in a purity greater than 99.5% from an initial feed of relatively pure isobutylene which further has minor quantities of tertiary butyl alcohol, water, polymers of isobutylene, and cis and trans-2-butenes in an economic manner while retaining good yields of the isobutylene by distilling the initial feed to separate a significant portion of the isobutylene with a...

Process for recovering hydrogen chloride from a gas withdrawn from an oxychlorination reaction zone which contains hydrogen chloride and water vapor wherein the gas is initially cooled, followed by contacting the gas with a small amount of water to absorb the hydrogen chloride from the gas. The water content is controlled to provide an aqueous hydrogen chloride stream having a hydrogen chloride co...

PURPOSE:To improve the system efficiency and to restore a failed state quickly, by performing input/output operation for a specified number of times for failure generation frequency and location, according to a failure retrieval section determined with the constitution of an input/output device, without intervention of a system control program. CONSTITUTION:A magnetic disc sub-system consists of a...

A petroleum distillate feed is upgraded and a substantial C3-C4 olefin product fraction produced by contacting the feed with H-ZSM-5 zeolite at (1) a temperature in the 500 DEG -800 DEG F. range, (2) a pressure below about 13 atmospheres gauge, and (3) an LHSV in the 0.1-15 V/V/Hr range, and fractionating the effluent product stream.

PURPOSE:To effect the fluid thermal decomposition of a municipal waste of high water content with good workability, operating efficiency and economically advantageously, by feeding pulverized chars to a bottom of a thermal decomposition furnace, and by the combustion in the zone with a high oxygen concentration. CONSTITUTION:The municipal waste 17 is fed to a fluidized bed with the screw 16, and a...

There are several barrier mechanisms, each including a base or diaphragm extending transversely of the roadway and related to the roadway by releasable anchors. In one version the diaphragm includes overlapping, transversely extending plates arranged to move transversely of the base. There are lateral buffer...

A powder coating composition is disclosed. The composition comprises at least one 1, 2 epoxy compound combined with a functionally terminated elastomer and a curing agent mixture. The curing agent mixture comprises an imidazoline derivative combined with an adduct of (a) a polyhydroxyl compound and (b) a diglycidyl ether of the polyhydroxyl compound, where reactant (b) is present in a less than eq...

A surface of a hot ribbon of glass, which has just been formed, is coated by directing a flow of coating gas substantially parallel to the glass surface under laminar flow conditions. The laminar flow is in the direction of ribbon advance or co-current to that direction, and the gas is released uniformly across the width of the ribbon. The coating gas contains a constituent, for example a silane, ...
