Abstract: Disclosed is a collapsible support base for supporting one end of an elongated shaft. The support includes four legs arranged in opposing pairs so as to form two cross members. The central portion of one cross member is flexible so as to be compressible to a smaller cross-sectional dimension, facilitating its insertion in a central portion of the other cross member. When interfitted, the two cross members are interlocked so that a preselected angular displacement between the legs thereof is maintained. In one embodiment, the cross members are pivotally interconnected one with the other at a central shaft-receiving portion. The central portions of the cross members may also include detent means for locking the cross members at a preselected angular position. The cross members may also be telescopically insertable one with the other with no provision for relative pivotal displacement.

Abstract: A free standing merchandiser or wire display rack is disclosed having a carrier detachably connected to a support means for supporting display merchandise such as books, food, or the like. The support means is formed as two elongated horizontally disposed spaced support rods that are offset both horizontally and vertically from one another with the upper support rod being located forwardly of the lower support element. The carrier has framework for supporting the displayed merchandise, and parallel mounting arms rearwardly upstanding from the framework terminating in novel hooks which hook onto a pair of spaced support rods. The hooks are formed with a first contiguous arm segment backfolded or angled relative to the upper part of the mounting arm to define a V-bend therebetween, and a second contiguous arm segment bent or angled relative to the first arm segment to extend in a direction away from the V-bend and the upper arm part.

Abstract: The disclosed collapsible stand has two sets of opposed legs extending radially from a tubular hub support, the stand being of the type that is collapsed or set up by rotating one set of legs relative to the other set of legs about the hub support until the legs are at 90.degree. to each other. Each leg is formed of an elongated rod back folded on itself to present inner and vertically spaced inner ends that are secured to the discs mounted on the hub support with an outer center portion of the back folded rod engaging the floor and serving as a foot for the stand. The inner ends of the legs are sandwiched between a pair of discs movably and rotatably mounted on the tubular hub support. Two pairs of locking or detenting tabs are upstruck from each of the lower discs, each pair of tabs being spaced apart to define a leg receiving slot therebetween. Preferably, the inner ends of the legs are each disposed between a pair of detents to provide a firm and stable support.

Abstract: A display arrangement including a source of polarized radiation; a magnetic material capable of supporting magnetic bubble domains in the path of the polarized beam, for producing a modulated beam; a device for representing an image encoded signal by means of the magnetic bubble domains; and a display device in the path of the modulated polarized beam for providing a visual display of the encoded image.
