Abstract: Articles (16, 18) are shrink mounted onto a stiff carrier or backing (10) and simultaneously selectively masked for paint spraying of the interiors of the articles (16, 18). The articles (16, 18) are secured to the backing (10) by a thin gauge plastic film (20) drawn under heat to shrink its dimensions while a vacuumizing head (50, 51) forms portions of the film to effect masking of selected edges (26, 28, 29) of the articles (16, 18). The interiors of the articles may be spray painted through openings (30, 31) in the backing (10), with the masked edges (17, 19, 26, 28, 29) of the articles (16, 18) protected from the paint (38).

Abstract: A portable frame having ground engageable wheels and a scale has an elongated linkage consisting of two pivotally actuated pairs of beams with reinforced cross members. A pivoted, hydraulic first motor is engageable with a hopper adapted to receive the dry mix ingredients. When the hydraulic motor is actuated, extendable movement of the piston causes the hopper to be swung upwardly and the hopper is simultaneously tilted to a vertical position. At maximum extension of the hydraulic motor, a pivoted hydraulic second motor acting at one end through one of the linkages and through the hopper at the other, effects further tilting movement of the hopper, to a substantially vertical position. The ingredients are then discharged through a chute section of the hopper into a self-transit concrete mixer truck.

Abstract: A cementitious product is produced from a combination of two groups of materials: the first group consisting of lime of Portland cement or Linfan (which is defined as a thermally cracked shell of calcium sulfate surrounding a core of lime) or Linvein (a lime particle coated with cracked calcium carbonate); and a second material consisting of thermally cracked fly ash which is cracked by thermally quenching such finely divided particulate material from an elevated temperature at least above 300.degree. C. and preferably higher than 450.degree. C. to ambient or below ambient temperatures.The two materials are blended together. They are mixed with water, placed in a form, and then allowed to cure. Filler materials can also be used in the form of sand, gravel, and other aggregates, depending upon the strength and compositional characteristics desired in the final product.

Abstract: A solid pollution-treatment product consisting of a core material of lime, quicklime or hydrated lime. The core is surrounded by a cracked shell formed of either calcium sulfate or calcium carbonate, such materials being referred to in this and prior applications of inventor by the coined terms "Linfans" and "Linveins", respectively.The described particulate material is particularly reactive to sulfur oxide bearing gases. Reactivity of such core material is even further enhanced by increasing its porosity through hydration and used in either the hydrated form or a selectively, partially or wholly dehydrated form before exposure to the sulfur oxide pollutants intended to be removed from flue gas or the like.

Abstract: A heating system comprising the combination of storage vessels (10, 12) for conventional heating oil and waste oil, respectively, and in which the two storage vessels (10, 12) are effectively sealed apart, one from the other. At the initial stage of heating, conventional heating oil generates temperature of a predetermined amount and the waste oil from vessel (12) is thereafter utilized after having been heated either from a feedback of heat (26, 28) developed by the conventional heating oil from vessel (10) or by a separate electrical resistor element (133), such heating making the waste oil effective as a heating medium. The flows from the two storage vessels (10, 12) containing the waste oil and conventional oil, are pressure controlled (64, 84) so that relief pressure feedback (70, 82) is provided in each distribution network (14, 30).

Abstract: In a multi-layer ceramic package, a plurality of ceramic lamina each has a conductive pattern, and there is an internal cavity of the package within which is bonded a chip or a plurality of chips interconnected to form a chip array. The chip or chip array is connected through short wire bonds at varying lamina levels to metalized conductive patterns thereon, each lamina level having a particular conductive pattern. The conductive patterns on the respective lamina layers are interconnected either by tunneled through openings filled with metalized material, or by edge formed metalizations so that the conductive patterns ultimately connect to a number of pads at the undersurface of the ceramic package mounted onto a metalized board. There is achieved a high component density; but because connecting wire leads are "staggered" or connected at alternating points with wholly different package levels, it is possible to maintain a 10 mil spacing and 10 mil size of the wire bond lands.

Abstract: A vertical tunnel kiln (10) comprising a firing kiln (30) having a interior core (42) supporting a spiral chute (46) attached to the periphery of the core (42). A vibratory bowl feeder (20) automatically feeds parts (100) individually to the upper end (24) of the spiral chute (46), and the parts (100) progress down the chute by means of vibrations imparted to the interior core (42) and chute (46) by a vibratory mechanism (40) attached to the annular base (47). Heating elements (38) and (70) are disposed exteriorly and interiorly, respectively, about the interior core (42) to produce a temperature gradient. As the parts (100) advance along chute 46, resistive materials on the parts (100) are heated in the preheat section (54) to remove volatile organic materials, fired in the intermediate portion (55) of the firing kiln (30), and then cooled in the cooling portion (56). The parts (100) are removed individually by an escapement mechanism (80) attached to the lower end of the spiral chute (46).

Abstract: In a hydraulic press for briquetting loose powders into green compacts, a load cell senses maximum compacting force. The maximum compacting force is compared with a compacting standard force known to effect a particular weight and density of compacted briquette. There is next operated a closed-loop servo network which adjusts the peak force to the standard force by varying the initial size of the cavity receiving the loose powders. Should the peak force be greater or less than standard force, an actuating mechanism is energized either to enlarge or diminish the die cavity for receiving the powder. If the peak force is too small, the initial die cavity size is enlarged so that a greater amount of powder is charged to the die cavity. The result is that when the final configuration of the briquette is reached, there will be greater density and greater weight to the briquette, causing it to more nearly approximate a standard briquette weight and density.

Abstract: A thick film is formed initially as a paste and made up of such oxidizable conductor ingredients as copper which is then mixed with glass frit and next printed on a non-conductive inert substrate by silk screening. The silk screen printed thick film with vehicle is then dried, and a coating of boron in suitable paste or paint form having been mixed with a thixotropic organic vehicle is covered over the entirety of the substrate and silk screen printed thick film. The resulting product after a second air drying is then fired to bond the glass frit-copper as a thick film onto the substrate, with the copper particles being sintered throughout into a thick film. Superposed boron, where contiguous with the copper printing, is fused as a protective layer over the copper allowing the sintering of the copper and bonding with the substrate to occur without oxidation of the copper.

Abstract: Apparatus and process for hot-stamping molded plastic containers in which the container is moved past a heated die having a platen with a printing die, the die being universally movable so that linear uniform pressure is exerted between a confronting container surface and die surface. As the container moves across the die surface, it is rotated so that foil which is pinched between the container and die is transferred onto the surface of the rotatable container. The uniform linear pressure between container and die, transfers foil to the accompaniment of rotation of the container so that defect-free lamination of foil is transferred onto the container surface to form decorative or alpha numeric information. The operation is continuous, with successively spaced containers moving into printing position relatively to the die, where the hot-stamping operation is repeated. Containers are automatically removed after printing, and successive containers supplied either manually or automatically.

Abstract: A looped cannula for administering oxygen and consisting of a flexible hollow tube having apertures disposed along a preselected midlength of the loop and at circumferentially spaced locations so that once the loop is encircled about the head of the patient and the loop is preferentially tightened, there will be a continuous stream of oxygen through at least some of the apertures directed toward the nose of the patient. The loop is held in operative position by means of a mounting member in the form of a fabric which is located at the crown of the head and has portions extending toward the anterior of the head and terminating in mounting sections. Substantially upright portions are operatively connected to the fabric and also to the loop, such upright members being located closely adjacent the ear and holding the loop in its appropriate location. Oxygen is continuously supplied to the loop through both of the open ends by means of a single oxygen supply line which is fitted into an adapter.
