Abstract: A solar collector panel is provided which has a pair of integral hook portions disposed along the longitudinal edges of the panel for corresponding contact with each pipe of a pair of adjacent solar collector pipes of a normal side-by-side solar collector pipe array. Adjacent hook members of adjacent panels cooperate to generally encompass, in a heat transfer relationship, a common pipe of successive adjacent pairs of pipes. Spring-biased fasteners attach the end panels to the main frame of the solar collector unit with the spring bias transmitted across the plurality of adjacent panels so as to introduce balancing forces to the cooperating hook members for clenching the common pipe therebetween as well as providing a solar collector panel/pipe array suspended from the main frame.

Abstract: A method and apparatus for impregnating low density fiberboard with asphalt is disclosed, and which includes stacking the sheets, placing the stacks in a sealable chamber, and flooding the chamber with a treating solution composed of a mixture of asphalt and solvent. The chamber is thereafter drained, and the fiberboard is then heated by the injection of live steam into the chamber. A partial vacuum is then drawn in the chamber, while condensing and separating the withdrawn solvent and water vapors. Both the condensed solvent and water of the steam injection system are maintained in closed conduit systems to permit their reuse and to prevent contamination of the environment.

Abstract: This invention relates to a process for producing crimped yarn or fibers which comprises spinning filaments from a spinning jet into a spinning bath and simultaneously subjecting said material to ultra-sonic sound vibrations so as to impart extremely fine and regular crimps onto said filament formed.

Abstract: A locking system for a railway car coupler includes a gravity lock member which defines a slot and a locklifter which includes a trunnion extending through the slot, terminating at a distal end. A flange is secured to the trunnion at the distal end. The flange prevents disengagement of the trunnion from the slot unless a predetermined orientation is achieved.

Abstract: An elongated longitudinally extending guide structure supported beneath the rear of a pickup truck with the forward end of the guide structure pivotally supported from the pickup truck frame for oscillation about a horizontal transverse axis. An elongated wheel supporting rack is slidably supported from the guide structure for longitudinal displacement relative thereto and the rack is shiftable between forward and rear positions relative to the guide structure. In the forward position of the rack front and rear ends of the latter are supported from the guide structure and when in the rear position, the rear end of the rack is disengaged from and displaced rearwardly of the rear end of the guide structure. The rear end of the rack and the rear end of the associated vehicle include coacting latching structure effective to latch the rack in its forward position relative to the guide structure and the latter in its raised horizontal position beneath the underside of the rear of the associated pickup truck.

Abstract: A process for the continuous filtration and aging of a viscose solution comprising xanthated alkali cellulose (XAC) is described wherein the XAC is continuously passed in a downstream direction through a series of aging tanks and a series of filter means. The aging tanks are so designed and arranged that the viscose solution is never partitioned into batches, as necessitated by common manufacturing systems, but constitutes a continuous, uninterrupted stream throughout aging filtration, deaeration and spinning. The filter means, standard plate and frame filters, are designed and installed in such a manner that the number of filter changes, or redressings, are substantially reduced in the aggregate, without increasing the number of filters now used in a standard plant, or sacrificing viscose quality. This results in less process interruption, loss of product, and less potential environmental pollution.

Abstract: This invention relates to a process and apparatus for the manufacture of viscose products which includes a motor means having a constant torque in the viscose during ripening wherein the resistance on said motor means changes as the viscose ripens because of the change in viscosity and the temperature is adjusted in response to said change in viscosity to heat or cool the viscose, and thereby control its rate of aging.

Abstract: A process and apparatus for making alkali cellulose having a desired predetermined degree of polymerization in which cellulose is steeped in an alkali hydroxide bath, generally 17-25% sodium hydroxide, and then passed through an RF treatment chamber where it is subjected to an RF energy field, to produce a controlled depolymerization thereof. Upon emergence from the steeping bath, the cellulose passes to an excess solution removing means, such as one or a series of pairs of nip rolls where the excess solution is expressed from the cellulose and the amount of absorbed alkali is controlled. Preferably, the excess solution is recovered and returned to the steeping baths. A second, lower concentration, steep bath may follow the RF treatment chamber.

Abstract: Improved process and apparatus for making alkali cellulose comprises continuously steeping indefinite length sheets of cellulose in an alkali hydroxide bath, generally 17-25% sodium hydroxide, and then passing the cellulose strip through a chamber where it is subjected to extremely rapid mercerizing conditions, including an RF energy field, to produce depolymerization thereof. Upon emergence from the steep bath, the cellulose passes to an excess solution removing means, such as one or a series of pairs of nip rolls where the excess solution is expressed from the cellulose and the amount of absorbed alkali is controlled. Preferably, the excess solution is recovered and returned to the steeping baths. A second, lower concentration, steep bath may follow the rapid mercerization step.

Abstract: A sampling apparatus for communicating with the interior of a vessel containing a liquid at an elevated temperature extracts a liquid sample of predetermined volumetric displacement from the vessel and maintains the sample at or above the elevated temperature or within a selected temperature range while conveying the same to a point of collection. If desired, an environment control medium may be maintained about the sample while within the sampler. In this manner, the sampler may advantageously be used to obtain samples of liquids which solidify, thicken, change in property and/or become unstable unless temperature controlled, or which must be maintained in a controlled environment during collection.
