When in use, the rack has major dimensions of approximately 40 inches .times. 7 inches .times. 7 inches and when collapsed and folded has dimensions of approximately 18 inches .times. 7 inches .times. 2 inches.

Abstract: A sampling apparatus for sequentially testing a plurality of samples by sequentially lowering the samples in a sample testing means and which includes a standard photographic slide projector and slide tray wherein the projector has a vertically upwardly opening gate, said tray has a plurality of vertically upwardly and downwardly opening slide slots and said projector has power driven means for moving the tray to sequentially advancing the slots into and out of register with the gate and power driven transport means to elevate slides dropped from each slot into the gate back up into the slot; a plurality of slide-like test sample carriers engaged in the slots to project upwardly therefrom and shiftable into and out of engagement in the gate, arms projecting from the bodies and having terminal ends spaced from the projector and about the testing means and test sample handling means at said ends of the arms to support samples to be lowered into the testing means when the body of each carrier is shifted vertical

Abstract: A substantially non-compacting carpet padding of controlled resiliency in flat sheet form comprising a mixture of staple fibers having lower indexes of resiliency and memory than is desired for such padding and flexible foam plastic granules having a greater index of resiliency than is desired for such padding and having a high index of memory, said fibers and granules being interengaged and interrelated whereby the fibers are acted upon by the granules to compensate for their lack of resiliency and memory and the granules are acted upon by the fibers to buffer and to compensate for their excess of resiliency.

Abstract: A vacuum packaging apparatus comprising an elongate tubular loading horn with front and rear ends, an elongate drive member shiftable axially forwardly to an actuated position within the horn, an item engaginf pusher at the forward end of the member and shiftable rearwardly from a normal forward position forward of the member to an actuated position, the front of the pusher normally projecting forwardly from the horn when the member is in its actuated position and occurring within the horn when the member and pusher are in their actuated positions, an elongate vacuum nozzle within and extending longitudinally of the pusher when the pusher is in its normal position and projecting forwardly therefrom when the pusher is in its actuated position, an elongate supply of tubular packaging film shirred axially on and about the exterior of the horn with a lead portion extending forwardly from the horn and closed by a sealing means, an item conveyor extending forwardly from the horn to support items enveloped in the le

Abstract: The method of hermetically sealing the ammunition between the bullet and casing of an ammunition round and establishing a jacket with a soft, lubricous, plastic inner layer of hydrogenated vegetable oil and a thin hard, dry frangible outer layer of carnuba wax on and about the bullet forward of the casing and about the forward portion of the casing, said method comprising dipping the bullet and forward end of the casing in a heated molten mixture of oil and wax and permitting the round to heat sufficiently to expand and drive air and moisture out of the casing between the bullet and casing, extracting the round from the solution and first chilling the surface of the solution on the round to cause the wax at and adjacent to said surface to coelesce, set and harden, whereby the outer layer of the jacket is established to contain the inner layer and to thereafter permit the round to cool and the oil and wax beneath the outer layer to solidify.

Abstract: The process for producing roofing felt which is softer, more flexible and more fire-resistant than such felt commonly produced by the prior art and which consists of permeating the felt stock with a treating fluid comprising a mixture of oil and soda ladened water, next drying the treated felt stock to remove excess moisture therefrom, next impregnating the felt with heated molten asphalt, next permitting excess molten asphalt to drain therefrom and finally permitting the asphalt in the felt to cool.
