Abstract: A double top-plate desk comprises a lower or first top plate 10, leg parts 40 for supporting the first top plate 10, and an upper or second top plate 20 which is substantially the same in size and shape as the first top plate 10, disposed above and substantially in parallel with the first top plate 10, slidably toward the rear (R) of the desk. The top plate 20 is slidable relative to the first top plate 10, from a state in which the two top plates are laid to overlap one above the other, toward the rear of the desk. To this end, a slide mechanism 30 is provided between the upper surface of the first top plate 10 and the lower surface of the second top plate 20 while supporting the second top plate 20 slidably toward the rear of the desk above the first top plate 10.

Abstract: A cutting board having a removable resilient band is provided. The cutting board includes a planar body defining a top surface, a parallel bottom surface and a uniform width peripheral side. The cutting board also includes a removable resilient band that is configured to engage the periphery of the body. The removable band has a width complementary to the width of the body and defines footings that each has a width greater than the width of the body. The periphery of the body may have a continuous groove and the removable band may have a continuous tongue that fits the groove.

Abstract: A springy panel bridges the ring mechanism housing. It is mounted on the ring halves so that when the ring halves close they cam the panel up the lower curve of the segments, and bow the panel upward away from the ring mechanism housing cover. An element having an upward end cam surface for paper or for a sheet lifter is mounted through two holes in the element on a lower segment of a ring so that one end of the element is inside the ring adjacent to the ring mechanism cover, the other end is inside the ring, adjacent to a line through the widest horizontal portion of the closed ring, and the element bows out of the ring between the two ends.

Abstract: Graphic material includes at least one area bearing a hologram and at least one area bearing a diffraction grating. Preferably, the diffraction grating and the hologram are simultaneously viewable from at least one perspective. The graphic material is made using an embossing die grown from a precursor blank which has been embossed in discrete areas with a holographic microtexture and then partially overstamped with a diffraction grating microtexture. The stamping of the blank may be effected by pressing a suitably shaped die against a shim bearing a diffraction grating microtexture for forming the microtexture in the die shape on the blank.

Abstract: This invention includes a method for heating a deposition material to form a vapor that may be deposited on a polymer film and thereby create a holographic film or similar material. Included within this method is a vaporizer that has an adjustable aperture. The vaporizer may have (i) a flexible wall that defines a cavity in which a deposition material is heated (ii) a first lip extending outward from a first side of the flexible wall and (iii) a second lip extending outward from a second side of the flexible wall. The aperture size can be adjusted to a desired cross-sectional opening by adjusting the distance of separation between the first lip and the second lip. By adjusting the size of the aperture, the flow rate of the vapor from the vaporizer can be adjusted to achieve a desired flow rate. Heat from a heat source in thermal communication with the vaporizer may be employed to heat the deposition material to form a vapor.

Abstract: A locking cam-type coupling for rapidly coupling two pipe sections together. A spring-biased lock pin is provided for each cam lever arm that has a positive locking action when the cam lever arm is moved to the closed position. Each cam lever arm is grooved to allow the spring-biased lock pin to contact the cam lever arm and control its position. The lock pin has two different diameters, one for locking the fitting to the complementary part of the pipe coupling to couple the pipe sections together, and a second, open position so the pipe sections can be released and decoupled.

Abstract: A ring capture mechanism of a loose-leaf binder includes a first plate having a U-shaped slot of continuous circumference designed to receive a ring of the binder through the slot within the circumference. The first plate moves across a second plate having a straight slot of continuous circumference designed to receive the ring of the binder, and locks the arms of a ring contained in both slots in the legs of the U-shaped slot.

Abstract: A die-cut sheet of material is folded in three and clamped by a ring binder mechanism so that two panels formed by the folding are pressed to a third panel that is between the folds, forming a binder cover leaf on each side of the mechanism. The ends of the folded panels are spaced from the fold lines, and may be fastened together to form a horizontal pocket, a vertical pocket, or horizontal and vertical pockets in both leafs.

Abstract: This invention includes an apparatus for heating a deposition material to form a vapor that may be deposited on a polymer film and thereby create a holographic film or similar material. A system and a method for producing such a film is also provided. Included within this system is a vaporizer that has an adjustable aperture. By adjusting the size of the aperture, the flow rate of the vapor from the vaporizer can be adjusted to achieve a desired flow rate. A heat source in thermal communication with the vaporizer may also be employed in the system to heat the deposition material to form a vapor. The vaporizer may be disposed within a vacuum chamber, which has a feed roll and a take up roll. As film is transferred from the feed roll to the take up roll, the vapor is deposited on the film. With the vaporizer of this invention, feed rates of about 1,500 fpm have been achieved.

Abstract: A material with holographic and non-holographic displayable indicia thereupon has an embossed holographic microtexture upon a surface thereof for forming a reflection hologram and resulting in an associated visible holographic pattern. A non-holographic pattern is printed with a printing press upon the embossed holographic microtexture at a predetermined orientation relative to the holographic pattern. The pattern may have several colors printed in registration and in registration with the holographic pattern which may include 2D and 3D indicia. A reflective coating overlies the microtexture and the printed pattern.

Abstract: A method for making transparent, reflective films includes coating a polymer film with ZnS by charging a set of carbon crucibles with ZnS cubes or pellets. The crucibles are heated by induction in a vacuum deposition chamber having a supply roll of the polymer film and a take-up roll. The ZnS cubes sublimate at a rate matched to web advance to insure a coating thickness for colorless films of at least 1,000 angstroms. The thickness of the ZnS layer on the film is monitored by visual observation of color by a source of visible white light and the rate of transfer of the film is adjusted to control the thickness of the ZnS layer.

Abstract: A flexible sheet having the back coated with a glue is formed into panels which are folded back on themselves with at least one layer being the back glued to itself by the coating. In one embodiment the glue is an energy responsive adhesive, and energy is applied to the folded sheet while it is on a cover, so that a cover having the cover liner with reinforced pocket is made.

Abstract: A decorative multi-colored material and method of making same using rainbow gratings simultaneously evidence different color patterns which change through the color spectrum. The patterns are formed from separate impressions from different portions of a common rainbow grating to provide color differentiation. The multi-colored material may be used for a variety of applications, for example, decorative package wrappings, stickers, product enhancement and the like.
