Abstract: Pourable products such as pool chemicals are packaged in a rectilinear stackable receptacle assembly. The receptacle assembly includes an upper cover or lid which includes a stacking recess into which a second receptacle assembly can nest. The receptacle assembly also includes a lower bucket portion which includes a continuous sidewall forming a rectilinear shape. The cover and the bucket side wall include interlocking members thereon which securely attach the cover to the bucket when the cover is pressed down against the bucket. The cover may include a pivotable bail handle, and also includes opposed side handles. The receptacle may include wheels partially located inwardly from one of the walls and upwardly from the bottom of the bucket.

Abstract: The present invention relates to the use of 4-(2-formyl-3-hydroxyphenoxymethyl) benzoic acid or physiologically acceptable salts thereof as an immunopotentiatory agent, compositions containing such a compound and their manufacture, combinations of such a compound with anti-tumour or anti-infective drugs and the use of such combinations in the prophylaxis or treatment of such diseases arising from tumours or infections.

Abstract: A modular stackable receptacle for pool chemicals or the like includes an upper cover and a lower container portion. The cover includes a continuous rectilinear sidewall having a latch ring on an inner surface thereof. An upper surface of the cover includes a product dispensing pour spout which receives a removable closure cap. The upper surface of the cover also includes a raised crown portion which is coplanar with the closure cap. Both the closure cap and the crown portion have stacking and aligning projections which cooperate with respective recesses formed in the bottom wall of the container portion, which recesses facilitate stable stacking of the receptacles, one atop another. The container portion has a continuous sidewall which includes an upper outwardly projecting rim and an outwardly projecting catch ring that is adapted to interlock with the latch ring on the cover, whereby the cover cannot be readily removed from the container.

Abstract: A high temperature electrical insulation system is provided by forming a winding in an electrical device from a conductor that is pre-coated with a first layer of at least partially cured inorganic material. A second layer of inorganic material is applied, either during or just prior to forming the winding, over the first layer in order to seal any cracks in the first layer. The resultant electrical insulative coating is cured following the forming process, essentially at room temperature. The insulation system provided is thus totally inorganic, and its manufacture does not require the use of organics, or heating to high temperatures to cure the coating or to cause pyrolysis and/or volatilization of organic elements, as did prior electrical insulation systems. Furthermore, because no organics are utilized in either the manufacture or operation of the insulation system, there is no residual carbon in the resultant coating.

Abstract: A process for making a continuous fiber reinforced thermoplastic article that is sufficiently strong and rigid for use as a structural member includes the steps of providing a tubular composite parison that has continuous, axially oriented glass fiber filaments dispersed in a thermoplastic resin and admitting pressurized air into the interior of the tubular parison to expand the tubular parison to a desired shape.

Abstract: A chimney is disclosed having a plurality of blocks including corner positioned ambient air downflow passageways and upflow passageways surrounding a central combustion gas conduit. Ambient air flows downwardly then upwardly around the conduit to prevent over heating in the lower portions thereof and to maintain the upper portions at a sufficiently high temperature to preclude the condensation of creosote and the like. A unique cap construction vents the combustion products and heated air through separate openings and inducts cool ambient air for the downflow conduits through a covered opening provided by a cover cap assembly.

Abstract: Apparatus for initiating compressive treatment of a running length of flexible material wherein the material is confined against a moving drive surface by a confining surface and then retarded by a retarding surface located downstream of the confining surface and spaced from the drive surface. The material is pressed into driven engagement with the drive surface by pressing the confining surface against it while maintaining the retarding surface in ineffective position. The retarding surface is movable toward the drive surface to increase the retarding effect until satisfactory running condition is achieved. The thus pressed confining surface may be shifted upstream while the retarding surface is shifted to engage the material in the region vacated by the confining surface.
