Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a smolder resistant upholstered furniture or mattress assembly and a method for render-ing the composite materials of such assembly smolder resistant.  Placement of a layer of sulphur immediately adjacent a normally smolder-prone material in the composite effectively prohibits the advance of smoldering combustion to a dangerous stage.  The sulphur layer is advantageously applied by backcoating the fabric overlay, coating or impregnating the  fibrous or polyurethane foam materials or separating layers of such materials with sulphur-containing films, fabrics and the like.  An advantage usly effective amount of sulphur is from about 25-50 g/m2 to about 250-300 g/m2 in a layer having a depth of about 1 to 3 mm.

Abstract: METHOD OF ASSEMBLING MOLDS     ABSTRACT OF THE DISCLOSURE    An improved method of assembling molds enables the size of successive molds to be adjusted to provide cast articles having a desired size.  In practicing the method, a first or initial mold is assembled in a fixture.  This initial mold is used to form a cast article.  The cast article formed in the initial mold is measured to determine the extent to which the dimensions of the article deviate from predetermined design dimensions.  The fixture is then adjusted to compensate for the deviations in the dimensions of the cast article from the intended or design dimensions.  A second mold is then assembled in the fixture.  Since the fixture has been adjusted to compensate for the inaccuracies in the first mold, a product cast with the second mold will have dimensions closer to the desired dimensions.

Abstract: ABSTRACT OF THE DISCLOSURE      A roof or wall structure incorporating support assemblies of this invention is disclosed.  The roof or wall structure comprises an inner sheath secured to plural spaced-apart purlins or girts; an outer sheath; plural spaced-apart support means each assembled from a plurality of the present support means, secured to the inner sheath and to the outer sheath for maintaining the outer sheath spaced from the inner sheath; and thermal insulation filling the space between the inner and outer sheaths.  The arrangement is such that the thermal insulation has a substantially uniform thickness throughout the roof or wall structure.

Abstract: ABSTRACT OF THE DISCLOSURE           Conventionally volatile esters such as ethyl acetate are produced by continously feeding an alcohol and an acid to an esterification reaction still containing an esterification catalyst, removing the ester and water so produced overhead by distillation and returning a proportion of the ester product as reflux to the distillation section in order to maintain the reaction mixture essentially anhydrous.  In the process of the invention, instead of operating the esterification still at atmospheric pressure as in prior art processes, superatmospheric pressure, typically in the range 1.38 to 13.8 bar absolute, is employed.  This results in higher ester production rates.  Although the process is applicable to the production of esters from either ethanol, n-propanol or iso-propanol and acetic, propionic and butyric acids, ethanol and acetic acid comprise the preferred feedstock.  Typically the reaction temperature is in the range 110 to 160°C.  Esterification catalysts include sulphuric acid and toluene-para-sulphonic acid.
