Abstract: A foldable jewelry card, capable of securing thereto an article or articles of jewelry, includes a front panel with a forwardly facing surface and a rearwardly facing surface. An intermediate panel is hingedly connected to the front panel, and interconnects the front panel with a rear panel hingedly connected thereto. The rear panel has a forwardly facing surface, a rearwardly facing surface, and a hook portion for supporting the card on a hanger. The rear panel and the front panel are attached to one another in such a manner that the front panel is securely interlocked with the rear panel. The intermediate panel causes the front and rear panels to be at an acute angle with each other whereby the forwardly facing surface of the rear panel substantially faces the rearwardly facing surface of the front panel.

Abstract: In monitor circuitry, a simple circuit separates out the horizontal synchronization pulses from the composite synchronization signal and removes undesired horizontal synchronization pulses during the vertical blanking period. By using a pulse-width modulated signal having the same frequency as the horizontal rate but not necessarily with the same phase, and having at least a 50% duty cycle, the undesired pulses are gated out before being coupled to the horizontal synchronization circuit of the monitor, thus, the monitor system will not attempt to lock at a double frequency, nor cause visible distortion of the raster. The effect of the pulse width modulated signal is inhibited when a user changes the horizontal synchronization frequency and until the monitor achieves lock on the new frequency.

Abstract: A modular clip is adapted to releasably secure together a pair of articles for movement as unit. Each article has an article body, a lug protruding from the article body, and a transversely-extending flange at the free end of the lug. The clip includes a generally planar clip body defining a central T-shaped opening therein including a wide aperture zone with widely spaced sides and a narrow aperture zone with relatively narrowly spaced sides, the wide and narrow apertures zones being in operative communication with one another. Each of the narrowly spaced sides defines a plane inclined relative to the clip body and extending from the adjacent wide aperture zone to adjacent a far end of the narrow aperture zone, whereby the inclined planes of the clip may be pressure fit intermediate the article body and the article flanges to preclude accidental displacement of the clip from the articles when the pressure-fit clip holds in juxtaposition the lugs of a pair of adjacent articles.

Abstract: Unwanted electric fields in the area in front of a CRT can be produced by flyback voltage pulses which occur across the horizontal deflection coils and are coupled to the inner DAG coating of the CRT. The unwanted fields can be eliminated by providing voltage pulses equal and opposite to the causative voltage pulses and applying the provided voltage pulses to the inner coating and the anode button, leaving no fields to be cancelled in the relevant area.

Abstract: An improved gravity feed display system and display card for the display of jewelry articles and the like. The gravity feed display system comprises pairs of inclined slots spaced apart to slidably receive the display cards in such manner that when a lower card is pulled out, a card situated adjacently above slides down to occupy the position of the card being removed. Each display card comprises a generally flat panel and a top flange, and means to prevent the overlapping of an adjacent card while in the display system.

Abstract: An improved image transfer device for transferring light images or the like is formed using "in-situ" optical waveguides or transfer elements rather than discrete optical fibers. In one embodiment, at least first and second tapered modular spacers are formed with grooves etched therein extending between first and second end surfaces thereof. Each of the grooves has a raised lip structure which enables the spacers to be interconnected in a rigid confronting relationship to produce a plurality of closed tapered channels. Each of the channels is then filled with a conductor to form an optical waveguide for transferring an elemental portion of an image between the first and second end surfaces.

Abstract: A combination holder for an ornamental article and protector therefor is disclosed and includes a substantially flat card member on which the ornamental article is mounted. A cover member having a dish-like configuration receives the card member therein, the cover member having a front wall that is located in spaced relation with respect to the front surface of the card member when it is mounted on the holder so that the ornamental article as mounted on the card member is protected by the cover member during shipment and/or display of the card member and the ornamental article.

Abstract: A method and apparatus for making fiber optic light transfer devices has apparatus to continuously supply a selected number of optical fibers, apparatus to form those fibers into a ribbon and adjust to different wrapping radii of a wrapper. The wrapper is in the form of a rotary wheel on which there is mounted a matrix former and a spaced ribbon former. The end of the ribbon is clamped to the rotary wheel and as the wheel is rotated successive wraps of ribbon are made on aligned U-shaped support surfaces of the formers. A separator is positioned between each ribbon layer in the matrix former and a channel-shaped locator element is positioned on the spaced ribbon former before each ribbon layer is wrapped thereon. A reflective glue is added to the layers in both formers. A clamp clamps the wrapped layers in each former after which they are cured in an oven.

Abstract: A fiber optic light transfer device with variable resolution comprises a plurality of optical fibers arranged at one end thereof as a series of spaced, parallel fiber ribbons. The ribbons are supported in a locator body having a plurality of spaced, parallel slots therein each defined by first, second and third support surfaces and an end surface of the locator body. Each of the slots includes one or more projections selectively spaced along the first support surface for supporting the associated fiber ribbon in the slot such that one or more of the fibers therein are are in a spaced relationship. Preferably, the fiber optic light transfer device includes "n" parallel fiber ribbons each including "n" optical fibers.

Abstract: Light transfer apparatus and method and apparatus for making disclosed includes a screen row clamping assembly that clamps a row of screen units side by side in a straight row with uniform spacing of fiber ribbons between units. A matrix row clamping assembly clamps a row of matrix units side by side in a straight row with uniform spacing of fiber ribbons between units. A pair of alignment rods connect screen units side by side and also connect to alignment ribs on the back of the screen units that interfit end to end and are joined by connecting channels. The alignment rods fasten to terminator bars secured to a screen frame and the ribs are also secured to the screen frame. The rows of matrix units are placed in a matrix frame in which they are held together in a square configuration with uniform spacing between and alignment of fiber ribbons. The matrix ends are cut to a planar surface by a band saw.

Abstract: A fiber optic light transfer device has a plurality of optical fibers with first and second end surfaces. A locator body for the first end surface has parallel slots through which the fibers extend and by which the fibers are located and mechanically held against movement relative to one another in three mutually perpendicular planes. The locator body has ear projections along the back as well as a projection and socket for aligning and connecting two locator bodies side by side. The locator body has a series of ridges and grooves along opposite surfaces which enable them to be connected in a columnar arrangement. A separator is disposed between each ribbon for disposing the fibers forming the second end surface in substantially parallel planes. These separators and ribbons are integrally joined by glue to form a matrix body. The matrix body has a series of ridges and grooves which assist in aligning and connecting them side by side and end to end in an assembly.
