Abstract: Disclosed is a wall framing system having vertical and horizontal mullions each formed of an interior piece and an exterior piece connected together by internal plastic clips. Water diverters are mounted internally of the horizontal mullions for diverting intruded water to exit points on the exterior sides of the mullions. At the crossings of vertical and horizontal mullions, internal water diverter bridge pieces connect through the vertical mullions from the water diverter in one horizontal mullion to the water diverter in the other. The vertical mullion faces each have a height substantially equal to a coextensive with the panels they grip to facilitate glazing and reglazing. A special open channel horizontal mullion with joint forming flanges therein is disclosed, together with a novel snap lock cover system therefor. Installation of the wall system is facilitated by deep glazing pocket vertical jambs, the two piece vertical mullions, and assymetrical glazing gaskets.

Abstract: A wall structure having a framework, for supporting a plurality of panels in horizontal and vertical alignment, the wall structure being installable in an opening of a building structure to close such opening with the panels being installable in the framework either from the exterior or the interior of the building structure. A wall structure may also be installed on the exterior of a building structure as a curtain wall. Frame members are made up of interior and exterior box-like sections, which are connected together by insulating clips, working in connecting flanges on the sections, thus providing thermal isolation of the parts. The panels are gripped by gasketed flanges on the sections. Specific proportioning of the connecting flanges and gasketed flanges provides a metal free zone facilitating deglazing and providing room for internal water diverters.

Abstract: Disclosed is a narrow frame wall structure having panel gripping mullions formed of extruded metal. Typical vertical mullions comprise a mullion proper with a glazing pocket on one side and one half of a glazing pocket on the other side, a mullion stop attached to the mullion proper after installation of a panel, and a mullion filler snap-locked to the mullion proper and the mullion stop to provide the remaining half of the second glazing pocket, thereby providing easy glazing and adequate glass bite notwithstanding the narrowness of the mullion. Joints between vertical and horizontal mullions are formed with joint pins positioned internally of the horizontal mullions on internal splines, and abutting, passing into or through, the vertical mullion, with predrilled screw holes in the pin so located that a screw hole is positioned a predetermined distance from the side of the vertical mullion in every standard location of the pin.

Abstract: Disclosed is a water soluble transfer material of the kind in which transfer is accomplished by localized application of pressure on a portion of the material to implant or transfer part of it to a selected surface. The transfer material is a multi-component mixture including a non-resinated dry pigment having an average particle size between one and five microns, a first polyethylene glycol having a molecular weight in the range of 2,000 to 4,500, a second polyethylene glycol having a molecular weight in the range of 6,000 to 7,500, a third polyethylene glycol having a molecular weight in the range of 400 to 800, a non-ionic emulsifier or plasticizer, and optionally an inert filler. Articles incorporating the transfer material include seamtress' transfer paper, business carbon paper, crayons, lecture pencils, and the like. The transferred markings are readily removed from the receptor surface by water when this is so desired.

Abstract: Disclosed is a compact heat exchanger particularly useful in a vaporizer application, such as a liquefied petroleum gas fuel system. The working fluid side of the exchanger includes a vapor film area of restricted cross section, which may be located at the upstream end, downstream end, or in a mid-region of the exchanger. The vapor film area effectively dams or blocks passage of liquid droplets and thereby aids in the vaporization process.

Abstract: Disclosed is a multi-functional grid structure for use in a vapor-liquid contact apparatus which includes a plurality of layers of relatively thin ribs. Some layers of ribs are flange-free and act as liquid distributors. Some layers of ribs include ribs with flanges and act as vapor-liquid contact devices. Some layers of ribs may have ribs with flanges having upturned edges which form channels, and such layers act as liquid collectors. A single grid structure performing these multiple functions normally requires only a single support structure, thereby saving on tower structure and cost.

Abstract: A pair of torque driven pneumatic tires serially feeds pre-assembled finger jointed boards, aligned end to end, along a path with sufficient force to overcome a drag force imparted to the boards at a point disposed in the longitudinal direction of travel. The drag force is produced by a retarding unit positioned downstream of the tires for engaging opposite surfaces of the boards passing therethrough with conforming bearing surfaces and producing uniform normal forces and friction thereupon. The boards along the path between the points of feed and drag are thus subjected to longitudinal compression facilitating complete interengagement in the finger joint.
