A separator plate for the negative electrode of a lead-acid battery comprising a molded, synthetic plastic wall or planar member of generally rectangular configuration. A pair of like separator plates are vertically oriented in the battery casing to sandwich the negative electrode therebetween including juxtaposed retention mats common in such a negative electrode assembly. The sandwich provides a...

PURPOSE:To produce a long life plate for a lead battery without using a meshy material by packing molten lead into the spaces between porous particles of a lead oxide powder. CONSTITUTION:First, a lead oxide powder is granulated into particles 2. Next, after the particles 2 are packed into a mold 4, molten lead 5 is injected into the spaces between the particles 2 by means of a pressure injector 6...

A multi-cell battery constructed of a plurality of frames of insulating material each frame having a number of active battery material areas arranged side by side with a division portion between each material area, the frames being arranged side by side in a direction normal to the plane of the frame with the division portions secured in sealed relation to form partitions between adjacent cells of...

A device for joining together two ends of a yarn in order to recreate the initial structure of the yarn comprises two heads provided with radial slots and fixed to rods which are rotatable in order to take up the yarn by means of the slots and to wind the yarn about the rods. The free ends of the yarns are untwisted and subjected to electrostatic fields created between the heads and an annular ele...

A powder metallurgical process for producing dense low-alloy ferrous parts having selected carburized surface portions in which a metal powder of the desired composition is briquetted into a shape-retaining preform, the preform is masked, sintered, carburized whereafter the mask is removed and the resultant preform is forged to a desired final shape. The forged part is then quenched immediately fo...

A process for afterburning and purifying process exhaust gases, which contain combustible constituents, wherein the process exhaust gases and the oxygen-containing gases required for a combustion are separately supplied to a fluidized bed reactor of a circulating fluidized bed. In the fluidized bed reactor, the gas velocity is adjusted to 2 to 10 m/s (empty pipe velocity), the mean suspension dens...

Improved integral skin microcellular polyether polyurethane elastomer products, e.g., shoe soles, which are characterized by outstanding low temperature dynamic flex and green strength at demold, at specific gravities as low as about 0.4 gm/cc. These elastomer products are desirably prepared from a two-component system, e.g., the reaction of Package A containing improved normally liquid quasi-prep...

A surface treating agent for a shaped article of a polyolefin is provided which is composed of a solution in an organic solvent of a propylene-ethylene copolymer having a monoalkyl ester of a monolefinic dicarboxylic acid, such as monomethyl maleate, grafted thereto. The propylene-ethylene copolymer has a propylene content of 50 to 75 mole %, and a crystallinity, determined by an X-ray diffraction...
