Title: Variable power telescopic sight
Inventor: FISHER TIMOTHY D
IPC: F41G1/38
Filed: 1996-10-11
Granted: 2004-12-21
Abstract: A variable magnification telescopic rifle sighting means includes an externally-located zoom adjusting ring rotatable about sighting means axis and modified to provide a digitally-activated zooming feature, permitting an essentially instantaneous switching over the range of magnification settings. The switching means includes an annular recess on the periphery of the magnification adjusting ring suited to receive on end of a flexible cable.  The cable length is adapted to extend and be coupled to a grippable means that can slide longitudinally upon manipulation within a slotted bracket mounted on the rifle stock. A second protective collar embraces the modified magnification ring and has an aperture for control cable translation. The movement of the grippable means through its line of travel via the cable effects a concurrent shifting of the zoom adjustment ring setting.

Abstract: The implementation of two-dimensional decoding, necessary to achieve a reasonable array aspect ratio for a large content addressable memory, is achieved by having multiple match lines per physical row, these match lines being physically routed on top of the array core cell in an upper metal layer. To limit power dissipation in the resulting large-capacity content addressable memory, the match function is implemented by two or more NAND chains per word. Means for achieving the precharging and evaluation of these chains, and for implementing dummy chains for the provision of timing information, are also disclosed.

Abstract: A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a middle layer, or core, of a material stiffer than the first and second mutually interlocking zipper profiles, and may also have a bottom layer of a sealant material. In use, the laminated film strip is folded over, and the zipper profiles are interlocked with one another. In doing so, portions of the top surface of the laminated film strip face inwardly, so that the folded film strip may be closed with a heat seal. The outside of the folded peel seal zipper tape, that is, the bottom layer of sealant material is bonded to plastic sheet material from which reclosable plastic bags or packages are made. In the production of the bags or packages, the mutually facing portions of the laminated film strip are sealed together. The resulting seal gives a visual indication of having been broken when initially opened.

Granted: 2001-12-25
Abstract: A sign adapted to be quickly and easily attached to and removed from a rope. The sign has a split-T portion defining flexible arms. The arms are bent to allow the rope to slide through transition slots to ultimately enter rope engaging channels. The arms are then released so that the transition slots have a width which restricts passage of the rope, thereby confining the rope to the rope engaging channels. The deflecting portions of the arms are located near the center of the sign to correspond with the natural position of a person's thumbs when holding the sign. The sign allows a new method for attaching a sign to a rope to be used, in which both arms are simultaneously bent from the center of the sign to insert the rope in the rope engaging channels.

Title: Method and apparatus for delivering a cased glass stream
Inventor: SCOTT GARRETT L
IPC: C03B7/084
Filed: 1998-07-28
Granted: 2004-03-09
Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass that includes a spout for delivering core glass from a first source through a first orifice. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by an annular chamber that communicates with the second orifice through a gap between the first and second orifices. A tube delivers casing glass from the outlet opening of a casing glass spout to the annular chamber in such a way that glass flows by gravity through the orifices from the first and second sources to form the cased glass stream. A hollow tube within the casing glass spout is positioned with respect to the spout outlet opening for metering flow of casing glass through the outlet opening and delivery tube to the annular chamber surrounding the orifices. The interior of the hollow tube is coupled to a source of gas under pressure so as to maintain the tube interior, and the interior of the thin fall of casing glass through the spout outlet opening, at a pressure above ambient pressure surrounding the casing glass spout. This elevated gas pressure within the casing glass fall reverses the pressure differential between the interior and exterior of the spout outlet opening, so that any tendency for air to migrate through the refractory material surrounding the outlet opening and into the casing glass fall is eliminated.

Title: Optical transparency having a diffuse antireflection coating and process for making it
Inventor: YAN YONGAN
IPC: G02B1/11
Filed: 1997-11-12
Granted: 2002-04-02
Abstract: A coated transparency, and method for making it, is disclosed, the transparency having a multi-layer antireflection coating that provides high transmittance with low specular reflectance, yet that also provides reduced visibility of surface defects. The coating includes alternating layers of polymerized silicon dioxide and polymerized titanium dioxide on a transparent substrate, with at least one of the layers incorporating discrete particles having a refractive index different from that of surrounding polymer. This provides the coating with a diffuse reflectance that is comparable to, or larger than, its specular reflectance, yet that still is negligible when compared to the coating's transmittance. The diffuse reflectance creates a loss of contrast for any reflected image or glare, thus masking any surface defects and providing a comfortable visual appearance. The successive layers of the antireflection coating are deposited on the substrate by applying separate solutions of an alkoxide, and alcohol, and water, and by curing the layer at an elevated temperature before the next succeeding layer is applied.

Abstract: The process precipitates additives onto nickel hydroxide seeds in an ammonia solution. Then introducing at least one metallic additive into the aqueous solution creates a slurry having a reducing potential. The additive is selected from the group consisting of aluminum, cadmium, cobalt, indium, iron, manganese and zinc. Introducing oxygen into the additive-containing slurry at a controlled rate maintains the reducing potential of the solution. At least one of the additives dissolves into the aqueous solution in excess of the slurry's solution solubility to precipitate the additive in the form of a hydroxide on the nickel hydroxide seeds.
