A metal strapping band to support flexible insulation within a wall cavity between spaced-apart wall studs, which strapping band comprises an elongated, metal strapping band having a plurality of uniformly spaced-apart lines of weakness therein extending from and adjacent at least one edge thereof, to define a plurality of defined tab elements in the plane of the band, which tab elements may be bent outwardly from the plane of the metal band, to form a support for flexible insulation to be secured within the wall cavity between the wall studs, the insulation supported by securing the metal strapping band to and across the wall studs, and bending outwardly the defined tab elements and impaling the flexible sheet material on the bent tab elements.

Strapping band for retaining insulation between wall studs and method of

An insulated wall system and method of construction, which system comprises: generally horizontal metal strapping bands secured to a wall, the metal strapping bands characterized by lines of weakness therein adapted to form tab portions from the metal strapping bands; a solid-panel insulating material placed against the wall and secured by a tab portion of the generally horizontal metal strapping bands, the tab portion extending about one edge of the panel material and against the interior side thereof, so as to secure the panel material against the wall; a generally vertical, metal-bank strapping material secured to the interior tab portion; and wallboard or finished wall material secured to the generally vertical metal-band material, thereby providing for an insulated wall system and method of construction employing solid panel material, without the requirement of wall studs.

In a method of preparing the enzyme, urease, from jack beans, wherein the jack beans are reduced to a fine particle size and the fine particles so reduced constitute urease, the fine jack-bean particles thereafter irradiated for a period of time, the irradiated jack beans then recovered and employed as a source of urease enzyme, the improvement which comprises: irradiating the whole jack beans prior to any size reduction of the seeds of the jack beans, to provide a urease derived from the white seeds of the irradiated whole jack beans having an improved activity level.

Method of preparing high-activity, low-bacteria, urease enzyme

A process for the expansion of an expandable, polymeric, bead material by exposing the bead material to steam at an elevated temperature, to effect the expansion of the bead material into a polymeric bead material form, while tumbling the bead material during expansion to prevent fusion, the improvement which comprises: employing as a lubricant for the bead material a lubricant material which, on exposure to the steam and prior to the end of the expansion of the bead material, is changed in lubricant characteristics, to provide an expanded, polymeric foam bead material having a reduced surface lubricity.

Method of preparing expandable polystyrene

A chemically embossed cellular vinyl chloride resin sheet material is prepared by treating the gelled surface of a vinyl chloride resin plastisol containing a blowing agent and a peroxide catalyst which induces polymerization of an acrylic monomer or resin with a liquid which contains an acrylic monomer or resin subject to polymerization, and subsequently heating the treated gelled vinyl chloride resin sheet material to polymerize the acrylic monomer or resin and to decompose the blowing agent, whereby full expansion of the sheet material is prevented by the polymerization in the treated areas, thereby producing a chemically embossed product.
