Prezenta inventie se refera la o compozitie gelifiata si procedeu de obtinere a gelurilor pe baza de acid sulfuric aplicate la baterii mici cu plumb. Electrolitul gelifiat pe baza de acid sulfuric se obtine folosind silice coloidala, acid metastanic, sare de litiu sau de cadmiu, carboximetilceluloza, acid fosforic si acid sulfanilic.; Compsn. comprises a formulation of colloidal silica metastannic...

The transmission device comprises first (I) and second (II) groups of input and output gears arranged on either side of a set of input (22, 28, 34, 46, 56,40) and output (24, 32, 36, 48, 54, 42) gears which produce a given speed ratio. The presence of first and second clutches (18, 20) enables both sequential as well as non-sequential gear shifting between the groups of gears and/or the gear locat...

PURPOSE:To transmit a large clamping force to a multiple disk (friction) clutch speedily by installing an electromagnet supporting a yoke free of movement and a clamping member clamping the friction clutch as well as an adjusting means, moving the yoke, and adjusting an air gap between the clamping member and the electromagnet. CONSTITUTION:A differential case 17 is rotated by rotation and drive o...

PURPOSE:To achieve a large increase of rigidity with a simple structure as aiming at the promotion of lightweightiness by forming each rib along a load direction making each reaction force of both first and second gears act on a peripheral edge of these shaft supporting parts of a gearbox. CONSTITUTION:Ribs 50, 52 and 54, 56 almost along the load direction of load acting on each supporting part of...

PURPOSE:To prevent the occurrence of a bead or the like to a pipe inner surface by forming each end of plastic pipes to be butted, while pressing the pipe ends heated up to a melting temperature in the opposite direction, and melting and binding them together. CONSTITUTION:Each pipe end 2 of plastic pipes 1 is cut into a taper form so as to project a pipe inner surface side 3 in a tube axial direc...

Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

of the Invention A venting unit is inserted in a press fit within the air vent of a rubber article forming mold and is comprised of a cylindrical body member with an axial bore having a reduced outer end section with an air inlet open to the mold cavity. The junction of the reduced outer end section with the main section of the bore is defined by a shoulder that provides a rubber severing member. ...

A venting unit is inserted in a press fit within the air vent of a rubber article forming mold and is comprised of a cylindrical body member with an axial bore having a reduced outer end section forming an air inlet open to the mold cavity. Received for reciprocal axial movement within the bore between an inlet closed position in abutting engagement with. the outer end section and an inlet open po...

A microprocessor controlled system for monitoring, storing and periodically reporting on data pertinent to the commercial operation of a reporting system, such as a soft drink vending machine, to a central data collection and monitoring computer, and which periodically reports such data over a telephone line which it accesses on a nondedicated basis. The microprocessor controls operations of the t...

In a process for the separation of nitrogen from air, gaseous air is compressed in compressor 2, cooled and purified in a reversing heat exchanger 12, and then distilled in a single distillation column 32 to obtain a pure gaseous nitrogen overhead stream 34 and an oxygen enriched liquid bottoms stream 36. All of the bottoms stream 36 and a portion of the overhead stream 34 are passed to a condense...

A pneumatic tire comprises a carcass ply (1), two vulcanized rubber composition layers (3) arranged radially inside the carcass ply, and a continuous layer of a sealing material (2) arranged between the two vulcanized rubber composition layers. The sealing material has a viscosity of not more than 6 x 10<4> poises at 60 DEG C. Bonding portions (1) are formed through the continuous layer, and disco...
