Abstract: INDUSTRIAL BATTERY STACK, AND APPARATUS AND METHOD       FOR STACKING, ALIGNING AND BURNING SAME     Abstract of the Disclosure A novel industrial battery stack is disclosed, wherein positive plates which have been longitudinally wrapped with a perforate or semi-perforate material are accurately aligned with respect to the negative plates and separators in the stack dur-ing the stacking operation.  The novel spacing members of the present invention have a generally U-shaped cross section for engaging through the wrapping a portion of the positive plate adjacent to the longitudinal edges of that plate.  Projections protruding substantially from the base of the "U" provide the pro-per distance between the edges of the wrapped plate and an adjacent longitudinal surface.  During the stacking and burning operation, this longitudinal surface comprises the back wall of a novel industrial battery plate holder.  Following the burning of the battery stack and its subsequent assembly into an appropriate industrial battery case, the spacing member or members act to protect the positive battery plates and retain them in their proper alignment during the operation of the battery.  Appli-cants have also provided a novel apparatus and method for stacking, aligning and burning industrial battery stacks which comprises a battery stack holder having several upstanding walls which define a stacking column having a coplanar terminus.          An adjustably locatable partition within said stacking column may be disposed at any of a plurality of positions parallel with respect to the coplanar terminus so that the battery stack holder may be adjusted for any of a variety of given sizes of plates and separators.  The battery plates and separators may then be stacked into the battery stack holder so that only the plate lugs extrude beyond the coplanar terminus.  A dam is insertable along the top of the battery plates and across the top of the upstanding side walls of the battery stack holder to facilitate the rapid efficient burning of the industrial battery stack.  This method is enhanced by the prior axial compression of the battery stack which effectively reduces the volume of the stack, and consequently the size of the industrial battery case required to contain a given amount of active bat-tery material.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and a machine for producing a latticework structure composed of cells of essentially parallelepi-pedon shape from e.g. paper coated on one side with synthetic resin.  The web is formed over a mandrel into a sleeve of square cross-sectional shape while being successively advanced, and the sleeve is cut into bits which are flattened and by a step-by-step feeding mechanism positioned adjacent one another with one bit overlapping the following one over halfway in the transverse direction.  The bits are bonded together while so positioned whereby flat elements are formed. These flat elements are stacked on top of one another by a mechanism ensuring that the elements are displaced by one cell width in their longitudinal direction and the stack of elements is then cut into pieces having the desired height of the cells.  When extended, these pieces form the desired cellular latticework structure.

Abstract: FLUID-OPERATED VISE                          Abstract A fluid-operated vise includes an elongate base struc-ture having a generally rectangular top surface.  An elongate undercut groove is formed in the base structure and opens through the top surface.  A pair of jaw structures are supported on the top surface and are movably positionable therealong.  Vise jaws are mounted on the jaw structures by interfitting dovetail for-mations which taper to draw the jaws into tight-fitting engage-ment with their supporting jaw structures while also serving to accurately position and orient the jaws relative to their sup-porting jaw structures.  One of the jaw structures includes a fluid-operated movable component for gripping workpieces between it and the other jaw structure.  Downwardly facing elongate grooves are formed in bottom portions of the jaw structures and communicate along their lengths with the undercut groove.  Elon-gate key members are positioned in the communicating grooves to maintain proper alignment of the base and jaw structures.  The key members also form parts of clamping systems which are oper-able to releasably retain the jaw structures in place at selected positions along the length of the top surface.  Groove and projection formations are provided on side and end portions of the base structure to permit interlocked, end-to-end and/or side-by-side positioning of a plurality of the fluid-operated vises.

Abstract: ABSTRACT OF THE DISCLOSURE      A basket, with no movable parts, for holding and dis-playing goods is provided with opposed bails at the upper end and support feet at the lower end, constructed and arranged to provide secure but separable stacking character by a separable interconnection of bails and feet of two sim-ilar baskets, wherein the basket construction effects resilient snap-together and locking of bails and feet to provide a stacking, or columnar, arrangement with great stability.  Addi-tional safety means to prevent inadvertent unstacking is pro-vided by cooperating elements on the baskets.  Two baskets may be nested, for reducing volume occupied by baskets when stored or shipped, by use of interfitting such baskets in an inverted and offset arrangement that is accommodated by slots defined adjacent basket corners.  A base basket and support base com-bination provides a very stable construction, that may have additional baskets stacked in a column upon the base basket, by use of wire elements that are shaped and arranged to interfit for maximizing resistance by the base basket to tipping relative to its support base.

Abstract: ABSTRACT  A fluid/particle separator unit comprises a cylindrical chamber having an inlet end substantially closed by an apertured rotor and an outlet, opposite the inlet, surrounded by a baffle wall extending coaxially within the chamber.  The rotor has vanes projecting into the chamber at an acute angle to the circumferential direction of motion in use and the chamber wall has elongate bleed slits.  In use in a particle-containing fluid flow, the rotor is rotated so as to oppose the flow through the inlet and separates particles from the fluid, cleansed fluid leaving the chamber through the outlet.  In a suction cleaner, the unit is mounted in the cleaner container so as to separate dust particles from air drawn through the cleaner, the dust collecting in the container; the rotor may be driven by a drive shaft coupled to the shaft of the impeller/motor assembly which causes the air flow through the cleaner.

Abstract: Abstract of the Disclosure For the combustion of finely-ground coal which is slow to ignite, the coal is preheated before it enters the combustion chamber.  The preheating can be carried out by passing cold air around the outside of the combustion chamber and then using this heated air to preheat the coal in bunkers.  For this purpose the combustion chamber is provided with a hollow casing surround-ing the combustion chamber proper and a partition in the hollow casing pro-vides an annular outer space and a concentric annular inner space.  A helical baffle arrangement is also provided in the inner and outer spaces to guide the cold air down the outer space and up the inner space.  The coal is burned below the melting point of the coal slag and this produces a soft ash rather than molten material.  The ash is cleaner and cannot bake onto burner housing.  Heat is stored in the combustion chamber wall and the time of residence of the coal in the combustion chamber is increased by impart-ing a spiral motion to the coal and/or air supplied to the combustion chamber.          The layer residence ensures more complete combustion.

Abstract: Abstract A seal for a bulk material circular cooler includes arcuate sections of flat, horizontally disposed rings directed inward from each upper side edge of the wind boxes. Horizon-tally disposed outwardly directed ring-shaped flanges depending from both arcuate bottom edges of the rotating cooler frame extend  outward  underneath  these  arcuate  sections.  Arcuate sealing strips mounted on the underside of the arcuate sections bear against the upper surface of the ring-shaped flanges to form a  sliding  seal  between  the wind boxes and the cooler frame.  The  arcuate  sections  are  bendable  in  the  vertical direction and  the weight of these sections and the sealing strips is sufficient to overcome the overpressure of cooling air bearing against the underside of the arcuate sections to maintain the seal.
