Abstract: A sealing assembly for a rotary kiln or furnace is achieved with a pair of outer sealing rings urged into a pressured sealing engagement by a barrier gas provided at a predetermined pressure from a burette. An internal intermediate ring, preferably formed of a graphite fiber material serves as an inner seal against the direct transfer of internal gases and heat to the outer sealing rings which provide the final sealing against gas escaping during rotation of the inner work support means relative to the outer stationary supporting means. The intermediate ring also acts as a bearing and as a spacer and absorbs compression forces between the turning inner chamber, or grate, and the outer stationary supporting means.

Abstract: A frangible bonding system utilizes blush lacquer as the frangible link in a system for bonding a substrate to a surface, such as the surface of a cover layer. The system is particularly adapted for packaging sterilized products. A substrate, such as paper, is coated with a layer of blush lacquer and dried. An adhesive, such as heat seal material, is superposed. A cover layer is overlaid, with a product between the layers. The package is then sealed and sterilized. Opening of the package is by peeling the cover layer and substrate from one another, breaking the cohesive internal bonds of the blush lacquer.

Abstract: In a process for refrigerating protein materials, the material is prepared as a viscous paste at a relatively hot temperature and applied to a refrigerated heat transfer surface on a rotating drum, the temperatures of the protein material and the drum surface having a predetermined differential to cause congealed or frozen liquid at the interface between the protein material and drum surface to initially melt and immediately thereafter congeal or freeze in order to cause adhesion of the protein material to the surface. The protein material is compressed against the drum surface to improve heat transfer characteristics and subsequently removed in a suitably refrigerated or frozen condition. Initial heating may be extended to render excessive fat or to reduce bacterial content. Opposite surfaces of the sheet of material may also be contacted by first and second refrigerated heat transfer surfaces either simultaneously or in successive order.

The card reader has two sets of light emitting means and two sets of light detecting means and the light detecting means are interconnected to provide a single set of outputs to comparators which measure the signal levels and provide distinct digital outputs. Selective energization of the light emitting means provides effective multiplexing of two multibit data words from a single set of outputs.

Abstract: A method and a DNA linker are described for synthesizing relatively long double-stranded deoxyribonucleic acid sequences of defined composition. Short complementary single strand segments of oligonucleotides comprising part of the full sequence desired are synthesized using known procedures. Overlapping single strand segments are annealed forming double-stranded fragments which are inserted in cloning vectors and cloned in an appropriate host, both purifying the DNA fragments and amplifying the amount thereof. An adjacent fragment is then similarly synthesized in quantity and such fragments are inserted adjacent to the first synthetic introduced fragments in the cloning vectors, followed by cloning in an appropriate host. The procedure continues until the entire desired sequence has been formed, at which time it may be excised or cloned directly in the vectors upon which it was made.

Abstract: A squeeze bulb dropper assembly is combined with a child resistant closure to form an assembly which cannot be readily removed by younger children. The assembly provides a vapor proof and leakproof connection with the bottle. The preferred assembly employs a closure having an outer cap and an inner cap in which the inner cap rotates with the outer cap in an application direction, but remains stationary relative to a bottle to which it is engaged when the outer cap is rotated in a removal direction unless a simultaneous downward force is applied to the outer cap to intermesh cooperating members on the caps. The closure includes a dropper bulb disposed through the caps so that a resilient compressible flange on the bulb provides the spacing between the cooperating members of the caps unless a downward pressure on the outer cap compresses the flange.

Abstract: A compact power driven ski bob is attained by locating the driving tracks of a rear power ski beneath the seat and pivotally mounting the front end of the power ski longitudinally forward of the seat. The rear end of the power ski is biased into engagement with the snow and is located lower than the front end of the ski to enhance driving contact with the snow. The seated operator is cushioned from impact forces and up and down movements of the power ski by a rear attachment means comprising a lost motion connection and a shock absorber. To aid in transportation of the snow bob, the front ski and the fuel tanks are detachably connected to the frame.

Abstract: An integral locking arrangement adapted for inclusion in different adjustable storage racks. Columns having rows of spaced apertures are interconnected by beams that carry suitable connectors, e.g., transverse lugs which are inserted into appropriate apertures. Downward movement of the lugs creates a camming action that solidifies the connection and aligns an integral locking tab with an aperture. Displacement of the locking tab causes its head to reside in an aperture in the column and prevents upward disengaging movement until the locking tab is withdrawn.
