Abstract: To a sheet of oriented polyethylene terephthalate a layer of nickel chrome alloy with an optical density of approximately 60% is applied by conventional vacuum deposition. To this sheet a subsequent stripe layer of stainless steel at 35% is applied by vacuum deposition down the center portion of the web which yields a combined optical density of approximately 21% over the center area. This first sheet is then laminated with a suitable optically clear adhesive to a second sheet of oriented polyethylene terephthalate incorporating a center portion which includes a nickel chrome stripe with an optical density of approximately 35% applied by conventional vacuum deposition. The resulting composite exhibits a vignette pattern of dark (optical density 7 to 12%) to light optical density 50 to 70% (from center to edge). A suitable optically clear mounting adhesive is then applied. When desired, the finished laminate contains a layer of clear PET which has been coated with a hard coat, i.e.

Abstract: A fluid distributing valve has the supply opening or conduit and the outlet openings or conduits disposed on the same side of the valve and oriented in the same direction. Accordingly the need for having couplings or unions to connect the supply pipe to the valve are eliminated. The valve includes a flow chamber or compartment and a control chamber or compartment so that the fluid passing through the valve does not flow past the operating members. By-passes are provided which may be finely screened to provide control water from the flow chamber to the control chamber. The valves are diaphragm operated, close, and remain closed against the flow pressure and are thus normally closed. They are open by a rotating operating cam whose operating surface moves cylindrical balls out of the way so that pressure in the control compartment can be exerted against the upper operating surface of the diaphragm operating members.

Abstract: In a variable radius pulley drive system wherein a flat drive belt engages the central shanks of drive elements supported by the side pulley sheaves and the radial location of the drive elements is determined by the intersection of logarithmic spiral grooves in the pulley disks of the pulley sheaves whereof the stresses on the bearing members of the drive elements can be substantially reduced by disposing the belt element driving line toward or on the center line or axis of the bearing members of the drive elements.

Abstract: A water softening system and apparatus utilizes two tanks, one for service and one for regeneration, and a control system operated by soft water flow controls the operation of all valves and the sequences of regeneration. The control system utilizes parallel plate valves for switching from one tank to the next, parallel plate valves energizing the piston moving the switching valves, and a parallel plate valve structure for distributing the regeneration water, as to amount of flow, direction and timing. A two-way to one-way cam structure initiates the operation of a control cylinder which supplies soft water to the metering valve and the regeneration valve as and where needed.

Abstract: The productive capacity of a drum heater and mixer for asphalt paving composition intended for processing recycled materials can be increased substantially by spraying a curtain of water vertically into the pathway of the raw material as it falls into the drum intake and before any substantial contacts with heated gases or flame and by spraying a curtain of water into the pathway of the heated gases and flame for controlling the temperature profile across the interior of the drum. The latter curtain of water is disposed at about thirty-five degrees to a plane perpendicular to the drum axis. Additional sprays of water downstream from the angular curtain of water may be supplied if necessary.

Abstract: The continuously extruding curb forming machine for roads, for example, may be equipped with a downwardly moving sharpened blade for use in the insertion of an expansion joint piece at appropriate intervals into the curb without stopping the operation of the machine while the expansion joint piece is inserted. The expansion joint piece may be well known felt material for this purpose and the inserting blade has a template attached thereto the surface of which conforms to the surface of the curb and thus to the surface of the expansion joint piece. As the blade moves into the partially cured concrete, the template forces the joint piece into the same concrete.

Abstract: A demountable solar oven includes a principal base upon which is mounted a secondary supporting base collar which contains the essential operating parts and which supports two removable arms at their base whose upper end form diametrically opposed pivots for receiving the appropriately disposed pivots of the cooking chamber. The food basket provided with similarly diametrically opposed pivots is disposed interiorly of the cooking chamber and by virtue of a weight disposed at the bottom thereof the wire basket always maintains a horizontal position irrespective of the angle of the oven itself. A transparent hemispherical cover including a shadow box indicator is disposed over the oven in the direction of the sun and a series of individual plate reflectors are hinged together by means of pins, a certain number of which pins are utilized to attach the reflectors to the oven rim.

Abstract: A rotational indexing nozzle arrangement has been devised wherein positive and consistent indexing action takes place under the influence of the application of fluid pressure and its relief by the action of an indexing or biased spring which becomes relaxed during the first stage (outward) movement of the indexing of the rotational nozzle head and which bites in and holds thereby causing the nozzle head to rotate during the second stage (inward) movement of the discharge head. The extent of the incremental indexing is determined by the length and angle of the biasing spring, or member. For improved operation a bearing of the ball or roller type may be disposed at the inward end of the nozzle arrangement whereby the resistance of the closing spring to rotation of the nozzle head is lessened.

Abstract: In a herringbone stall apparatus efficiency of operation is achieved by having the stall, the feeding equipment and individual gates for each stall carried by a single supporting and reciprocatable structure.
