Abstract: The machine of the present invention manufactures low-cost garments out of two plys of web material, preferably nonwoven material. It includes a pair of feeder mechanisms to supply two separate sheets of the web material through cutter mechanisms where the webs are cut into shapes suitable for the desired garment. The shapes of one sheet are larger than the shapes of the other sheet. The sheet with the larger shape is placed on a carrier, and the sheet with the smaller shape is placed thereupon. As the combined sheets are moved by the carrier, a plurality of folding mechanisms turns the edges of the larger sheet around the edges of the smaller sheet to create a seam which is subsequently secured, as by adhesives or sewing. The carrier may be either a rotating cylinder or it may move longitudinally. The seams may be created along machine direction lines, cross machine direction lines, or along lines at acute angles to either the direction of movement or perpendicular thereto.

Abstract: A microwave energy concentrating collector having a concave paraboloid reflector surface supported on a plurality of shaped supports, said supports being parabollically shaped on the top edge and extending radially from a circle near the axis of revolution of the paraboloid to its periphery, and arranged to coact with a reference means. The reference means may, in some embodiments, be equidistant from the central axis. In others, it may be a radially extending reference.The reference means insures accurate placement of reflector components for high accuracy focusing after assembly. It may be an indentation on the bottom edge of the supports coacting with an abutment, or it may be a vertical edge of the support coacting with an abutment. In other embodiments, the abutment may be an overhead template having a bottom edge which is parabolic in shape, said template being accurately located with respect to a horizontal reference so as to form an abutment for the parabolic shaped support.

Abstract: A solar energy concentrating collector has a concave parabolic reflective member supported on a plurality of shaped support assemblages, which are parabolically shaped on the top and extend transversely in a direction perpendicular to the axis of the collector.Each assemblage has a vertical planar support and also a flexible member. The flexible member has a top for supporting the reflective member and an appendage affixed to the top and extending away therefrom into operative engagement with the vertical planar support.The top of the flexible member can be moved against a template having a parabolically shaped bottom surface. The space between the top of the flexible member and the top edge of the planar support is bridged by the vertical downwardly extending appendages which are fastened to the support after the top has been properly positioned. The flexible member thus provides a correct concave upper surface having a parabolic shape that matches the accuracy of the template.

Abstract: A solar energy concentrating collector having a concave paraboloid reflector surface supported on a plurality of segments, said segments being parabolically-shaped on the top edge and extending radially from a circle near the central axis of revolution to the periphery, and arranged to coact with a reference means which is equidistant from the central axis at all points of revolution.The reference means may be a protrusion coacting with a cutout or other indentation on the bottom edge of a semi-parabolic shaped support whereby to insure accurate placement of reflector components for high focusing accuracy after assembly.

Abstract: A method of manufacturing a packaged web product and apparatus therefor wherein superposed webs are compressed and while compressed webs pass through an open-ended forming device having a closed perimeter and simultaneously enveloping the compressed, superposed webs, and thereafter transversely severing the resultant product into identical units.

Abstract: A solar energy collector is shown which is comprised of an underlying support, a support surface, and a combined reflector and heat absorber. The combined reflector and heat absorber is formed from a continuous sheet of material to provide contiguous parabolic reflectors, each reflector having an upstanding heat absorber centrally located therein in the form of a fluid conduit. The absorber-fluid conduit is closed along one edge by the support surface or by a spacer between support surfaces. A pair of manifolds are operatively connected at the ends of the heat absorbers to enable heat-absorbing fluid to flow in from one manifold, through the absorber-conduits, and out the other manifold. The continuous formation of the parabolic reflectors and heat absorbers from one sheet provides production economies, manufacturing efficiencies and reduced weight and cost of the solar energy collector.

Abstract: A cutting method and apparatus using a plurality of impact-type laser or water jet cutters mounted on a framework above a moving web. The cutters are disposed in a spaced relationship to each other along a line parallel with the direction of web travel. By spacing the cutters a distance substantially equal to the desired product length, each of the cutters simultaneously cut from the web similar portions of one side of each of two consecutive products. The cutters are arranged so that as the web moves one product length, each of said cutters cuts from the web on the other side of a substantially central axis similar portions of the other side of said products. Embodiments include means to increase or decrease velocity of the cutters when mounted on a second framework which is also movable in a direction parallel to the direction of the web movement.

Abstract: A solar energy concentrating collector having at least one reflector surface and at least one substantially planar vertical absorbing means coacting therewith for the purpose of absorbing reflected solar rays, said absorber being at least partially located in a plane coincident with the nadir of the reflector surface, the absorber surfaces being continuous and at least portions of one fluid conduit, and at least one horizontal extension of said continuous absorber surface being below said coacting reflector surface.

Abstract: This invention describes an inexpensive solar energy collector protective device that controls the flow of hot collector air within a pre-selected range. The device permits automatic opening of a vent, accomplished by a bi-metallic release or by rupturing of a separator. As a result of this construction, power failures, and the resultant failure of fluid pumping apparatus will not cause damage to the solar energy collector components. This protective device comprehends selection of inexpensive materials for internal components.

Abstract: This invention relates to a solar energy collector which utilizes spaced-apart shaped reflector surface supports and a reflective surface with apertures selectively located so that the device collects a portion of the solar energy to transmit same through conductors, and also allows a smaller portion of the solar energy to be passed to the side opposite the reflector surface, this device thereby being a combination solar energy collector and light-emitting panel.
