Abstract: A movable computer work processing system wherein a movable computer work station unit having a plurality of supporting surfaces in a housing thereof for supporting components of a computer work processing system is adapted to be moved over a desk. A slidably and pivotally mounted shelf means has a support surface for supporting components of a computer work processing system and is slidably moved out of the housing and pivoted until a portion thereof contacts the desk. The housing is provided with a slidably pivotally mounted front door means which is in a closed position when the housing is being moved and an open position when the computer work processing system is being used. Also, the front door means may be moved to a partially opened position to block off glare from overhead lighting.

Abstract: A rigid, self-sustaining plastic container is provided with cooperating notches and hooks for supporting a plastic bag, having handles secured thereto and wherein an opening is formed between each handle and the plastic bag, in the container so that the bottom of the plastic bag is adjacent to the bottom of the container and the open end of the plastic bag is held open so that items may be placed therein.

Abstract: The formation of tubular objects by spirally winding and seaming a relatively rigid strip of plastics material. A sealing flap (15, 215) along one longitudinal edge (5, 25) of the strip, and an engaging surface (16, 216) along the other edge (11, 211) positioned close to but separate from the interlocking portions (8 and 12, 28, 212) of these longitudinal edges. The provision of these sealing flaps and engaging surfaces permit the interlocking portions at the edges to be designed independent of the ability of these interlocking portions to create a fluid seal. This results in optimum operation of these interlocking portions to, for example, permit relatively rapid changes in the diameter of the tube as it is formed, as well as subsequent to its formation.

Abstract: Small amounts of ethoxylated (propoxylated propylene glycol) utilized as a surfactant/emulsifier for polyolisocyanate reaction systems for producing rigid foams that can produce at least 80% closed cell formation where the surfactant does not produce undesirable reaction products with the isocyanate and has an HLB less than 4.

Abstract: A fiberizing bushing having a plurality of cooling tube alignment members spaced from the tip plate of the bushing wherein only a small portion of the space is filled with a refractory cement.

Abstract: A railroad brake shoe composition free of fiber reinforcement comprising, in percent by weight:Phenolic Resin Binder: 1-15%Carbonaceous Component: 30-60%Organic Component: 15-30%Inorganic Component: 5-35%Friction Modifiers: 1-15%Additives: 1-7%.

Abstract: An electric melting furnace is provided for optimally melting and mixing a non-homogeneous material. The melting furnace includes a vessel having its top portion open to the environment. Three electrodes are supported above the furnace. Each of the electrodes includes a tip for insertion into the material contained in the vessel. The vessel further includes an outlet formed in the bottom wall of the vessel to discharge the material after it has been melted and optimally mixed. Each of the three electrode tips has a generally round configuration. During the melting operation, the three electrode tips are laterally spaced from each other and are positioned in the vessel to be surrounded by molten material but above the bottom wall outlet. Optimum melting and then optimum mixing of the material occurs at selected horizontal spacings of the electrode tips and at selected electrode tip immersions in the molten material.

Abstract: A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber. Air and fuel are metered to the burner with the amount of air being controlled such that the fuel/air premix contains at least enough air to start and maintain minimum combustion, but not enough to provide stoichiometric combustion. At a point immediately above the burner, additional air is metered into an insulated enclosure surrounding the expansion chamber where it is preheated by the heat passing through the chamber walls. This preheated additional air is then circulated back to the burner where it provides the remainder of the air needed for combustion, normally full combustion.

Abstract: Disclosed is a vehicle exhaust system containing a three-way catalytic converter. An insulated flexible duct connects the outlet of the engine exhaust manifold with the inlet of the three-way catalytic converter to retain the exhaust engine gases at a temperature greater than the ignition temperature of the three-way catalyst in the catalytic converter. The insulated flexible duct is preferably made of an inner flexible metal conduit surrounded by fibrous insulation which in turn is surrounded on the outside by a second flexible metal conduit. The system is economical, contains no active elements which would require maintenance or could get out of order, is adaptable to motor vehicles of all types (especially automobiles, light trucks and vans) including those powered by either gasoline and diesel engines and entirely eliminates the need for expensive and complicated light-off catalysts in the system.

Abstract: A method of deep embossing of sheet material, generally metal, is disclosed. A small scale relief pattern is first embossed across the entire sheet and thereafter a deep embossment of spaced-apart protuberances is imparted to the sheet. Both patterns in combination produce a sheet useful for reflective thermal insulation without the risk of significantly puncturing the sheet.

Abstract: This invention relates to a burner apparatus (10) suitable for use in the flame attenuation of glass filaments. The flame attenuation burners of the prior art are subject to deleterious deposits of glass that have not been properly attenuated by the burner apparatus. These deposits usually form adjacent to the outlet opening (20) in the refractory material constituting the combustion chamber of the burner apparatus (10). In use, these deposits are removed by a mechanical process which tends to cause damage to the refractory material (12) of the burner apparatus (10). The present invention incorporates a metallic protector or a plate (22) having a discharge passageway (26) having an area slightly greater than the area of the outlet opening (20) and provides a means to protect the burner refractory material (12) from damage during mechanical removal of any glass deposits.

Abstract: The present invention relates to a method and apparatus for the production of fibrous insulation, especially relatively thick fibrous insulation. Previously some relatively thick insulation has been produced through lamination techniques using a plurality of insulation layers, which possibly included the use of a continuous fibrous hinge as an alignment aid during lamination. However, proper alignment using a continuous hinge is difficult and leaves an objectionable bulge of fibrous material. The present invention eliminates the fibrous bulge of the prior art and provides a more accurate means by which to substantially accurately align the layers of fibrous insulation.

Abstract: Refractory fiber blanket blocks for electric furnaces having electrical heating elements mounted therewith by supports provide substantially improved insulation capabilities for electric furnaces when attached to the furnace walls. The support elements are in the form of holder members for receiving and support heating elements of the electric furnace and an arcuate spearing member which is capable of insertion into the insulative block at any desired location on an inner surface or hot face without requiring any anchoring structure for heating element support. The arcuate spearing member may take several forms and supports the heating element, engaging only the fiber blanket without anchoring structure for support.

Abstract: A thermal insulation device is described comprising a modular or block insulation composed of at least two layers of serpentine folded fibrous insulating blankets with the layers of blankets being secured by means of extended folds of the hot face layer being interengaged with folds of the cold face layer, with the cold face layer then being separately secured to attachment means for mounting the block on the wall, ceiling, door or other surface of a furnace, kiln or like structure. The layers of fiber are commonly composed of fibers of different compositions, with the more thermally resistant fiber comprising the outer or hot face layer and the less thermally resistant composition comprising the inner or cold face layer.
