PURPOSE:To improve high rate charge-discharge performance and a charge-discharge cycle life of a sealed lead-acid battery by using a lead alloy grid containing no Sb such as a Pb-Ca alloy and adding either or the mixture of boric acid and/or borate to an electrolyte. CONSTITUTION:By making an electrode plate thin by using an alloy grid containing no Sb such as Pb-Ca, Pb-Ca-Sn in a sealed lead-acid...

This invention relates generally as indicated to a servicer and more particularly to a servicer for supplying tire components to a building drum or shaper for the construction of tires, or more particularly for the construction of tire components such as belt and tread assemblies.

The residual metal content of tightly chelated heavy metal-containing effluents is reduced by carrying out a sulfide precipitation process in the presence of a seed material comprising an added unchelated soluble heavy metal salt, preferably with an adjustment of pH to at least above about 9.0, with optional variations including passage through a mixed filter media comprising at least two particul...

An installation for the purification of effluents, has a rake (0) an aerated sand trap (1), and adsorption stage (2), a culturing stage (3) and a final clarification stage (4). The discharge from adsorption stage (2) also passes through an intermediate clarification stage (5). No provision is made for sludge recycling between the adsorption stage (2) and the culturing stage (3). The tank aeration ...

The invention pertains to aqueous liquid detergent compositions of the suspending type which comprise a nonionic detergent active material and/or derivative thereof in admixture with an anionic detergent active material and/or cationic detergent active material, and electrolytes which consist of one or more salting-out electrolytes and one or more auxiliary electrolytes having a lyotropic number o...

PURPOSE:To shorten the reading time of an instruction for a small-scale instruction loop, by reading the instruction directly out of an instruction buffer while the branching conditions of a branch are satisfied. CONSTITUTION:For a small-scale instruction loop formed by a specific instruction loop, an instruction loop is assumed with a specific branch instruction. Then a detecting circuit 15 is pr...

PURPOSE:To improve the processing capacity for a data processor which has high processing performance, by invalidating the reading request before the transfer of data is over. CONSTITUTION:When the reading request is given to a storing part 2, an instruction processing part 1 feeds the invalid information showing that the reading request is invalid to the part 2 through a reading request circuit ...

PURPOSE:To shorten the executing time of an RR instruction, by skipping an address qualified stage and at the same time starting the decoding of the subsequent instructions at one time in case an instruction (RR instruction) exists between registers following a load/store instruction or a branch success. CONSTITUTION:When a load/store instruction (n) and an RR instruction 16 are consecutive, the i...

A method and apparatus for determining the parity of data bits that have been disassociated from their parity bits and regrouped by a data byte shifter/converter or like apparatus. The lack of usually available parity bit association is overcome by generating a parity bit for each of the groups, including the parity bits, formed by the disassociative procedure. The group parity bits are then logic...

PURPOSE:To facilitate an easy correction of errors, by providing an emulating function to a data processor to translate a program to translate the read-out program and to give a grammatical check to the translated program. CONSTITUTION:A program which is written to a coding sheet 1 and fed to an electronic computer is read by an optical character reader 2 and then converted into the character code...

Fluorinated derivatives of erythromycins A, B, C and D, having antibiotic activity, are prepared, starting from 8,9-anhydroerythromycin 6,9-hemiacetals or their N-oxides, through the reaction with a compound capable of generating electrophilic reactive fluorine, the resulting reaction product undergoing thereafter a reduction, possibly together with a methylation, to the corresponding (8S)-8-fluor...

The invention relates to a tubular reaction furnace for the indirect heating of crackable fluids, particularly for cracking hydrocarbons used for the extraction of gases rich in CO and H2, said furnace consisting of a plurality of vertical reaction tubes arranged in a firing chamber with internal fuel-gas burners. The invention primarily relates to furnaces in which cracking takes place at high pr...

A reaction furnace capable of functioning efficiently in off-shore process installations which comprises a plurality of vertical reaction tubes arranged in a firing chamber having one or more burners, and a plurality of horizontal beams, suitably hollow, having external insulation which extend through the central region of the furnace without impeding the fuel gas flow and to which one or more rea...
