Abstract: An annunciator apparatus has a light directing device that efficiently causes light to pass from a light source, such as a lamp, toward a generally flat surface of the light directing device in an efficient manner. The light pipe of the annunciator incorporates parabolic rear surfaces that are reflective. In addition, discs of partially reflective and partially transmissive material are disposed directly between a light source and the preselected plane toward which light is directed perpendicularly. The annunciator comprises an indicia plate which incorporates layers to accomplish the desired effect of having a reduced reflection characteristic. Indicia are represented on front and back surfaces of a substrate and aligned with each other to define a "pinhole" effect that significantly reduces light reflected back from the light directing device toward the viewer.
Abstract: An elongate produce information display tag for presenting product information at the distal end of a product support hook is useful on both wire-back hooks and plate-back hooks. The tag has a mounting portion with selective apertures by which the tab is engaged on the hook. One of the apertures is associated with a strip of contact adhesive extending across the mounting portion by which the tag can be adhered to the front surface of a back plate of a plate-back hook. The other aperture merges into a keyhole-type slot which can be used to embrace over the depending leg at the back of a hook by which the hook is welded to a back plate or rod-like bracket. The intermediate portion of the tag which extends over the hook has a fold down stabilizing tab which engages the hook and provides lateral stabilization of the tag.
Abstract: An improved mode of construction is provided for a display device of the kind comprising an array of triangular-section slats rotated in synchronism in 120.degree. steps to present repeatedly to view, in sequence, three compound display surfaces, each carrying a respective poster or the like. In embodiments of the invention, each slat has a respective bearing and driving module with a respective rotary member releasably drivingly engaging the slat and with a respective cam, driving the rotary member and driven in turn by a driving shaft, passing through the cams of the bearing and driving modules of all of the slats. The bearing and driving modules are received in a stack within a hollow extrusion which forms one side member of a frame of the display device. The opposite side member of the frame receives a stack of bearing members rotatably supporting the opposite ends of the respective slats.

Abstract: A diagrammatic indicator assembly includes a hollow, transparent housing which is substantially Z-shaped in side view with upper and lower terminal portions interconnected by an angled central portion. Each of the terminal portions define reservoirs adapted to carry a sandy medium stored within the housing. An inclined plate is mounted within the housing and includes opposing sides provided with a plurality of holes for retaining some of the sandy medium as it flows thereover. The housing can be orientated in a first upright position wherein the sandy medium flows over and is retained in the holes on one side of the plate and an inverted, upright position wherein the sandy medium flows over and is retained in the holes on the other side of the plate.
Abstract: An illuminant photo frame, comprising: a transparent frame body constituted by elongated lines and cross lines respectively having a back side created with a plurality of integrant 45.degree. prisms in more than one flight of stages to collectively form a certain pattern, a recess arranged at the back side of the naturally met elongated and cross lines in cross opposition to the other for installing a small bulb each thereat, and a photoresistance in control of electricity supply to small bulbs to have them transmit lights automatically at night, which sent from two sides of each recess to travel forward alongside elongated and cross lines will make an internal total reflection at each 45.degree. slant of the prism to project out of the front side, thereby, with a crystal illumination given to the pattern. And the electricity supply will automatically cease at daytime.
Abstract: An apparatus for displaying an advertisement or message inside a golf cup is comprised of a bottom disk releasably securable inside the golf cup, a sheet of material having an advertisement or message marked thereon, and a transparent top disk that is assembled to the bottom disk with the sheet of material enclosed therebetween. The top disk is assembled to the bottom disk by friction, sealing engagement between the two disks. The sealing engagement between the disks protects the sheet of material enclosed between the disks from the outside environment. The transparency of the top disk enables the sheet of material to display an advertisement or message marked on the sheet through the top disk. The message or advertisement displayed is visible from outside the golf cup into which the apparatus of the invention is inserted.
Abstract: Chair comprising an underframe, a back being pivotally connected to the underframe, a seat being pivotally connected to the back, the seat at its front edge also being pivotally connected to a foot rest which by a guide is so connected to the underframe that the angle which the foot rest forms with the seat varies with displacement of the seat. The control consist of sliding device being pivotally connected to the underframe and spring which impart a force impacting in the longitudinal direction to the sliding device in dependence on the position of the chair.
Abstract: A stand for mounting a device having a rib member includes a mast, with a pair of spaced mounting clips secured to the mast. The mounting clips are spaced from the outer surface of the mast so as to form pockets therewith for receiving the rib member. Upon insertion between the mounting clips, the rib member is pivoted for entry into the pockets and a locking pin receivable in an aperture in the rib member prevents a dislocating pivoting in an opposite direction.
