Abstract: A process for laying small decorative tiles on a surface includes the use of a lightweight plastic matrix having ridges of a desired pattern which are used to locate and space the tiles of different shapes in the desired locations. Tiles of the desired color and shape are placed face down on the matrix. A perforated paper matrix having an adhesive layer is then placed over the exposed back sides of the tiles to maintain their relative positions. The surface to be tiled is then coated with thinset adhesive and the tile strip with the matrix is removed and placed against the surface. Several such tile strips may be placed side-by-side or in a desired arrangement on the surface after which grout is applied between the tiles in a well known manner. The process for producing the paper matrix is also described.
Abstract: A switch housing assembly which uses an internal pressure bracket to simultaneously provide pressure against multiple switches located in multiple locations within the switch housing assembly. The pressure bracket creates a fluid seal between the flexible switch buttons and the switch housing by pressing the switches against the switch buttons which in turn are pressed directly against the inner surface of the switch body. Multiple switches are simultaneously secured to the switch housing by an internal bracket which simultaneously provides pressure against the backs of multiple switches. An optional pressure ring focuses pressure from the periphery of the switch assembly to the outer peripheral ring of the flexible switch button. The bracket assembly is preferably secured to the switch housing by a single removable screw to allow disassembly when needed.
Abstract: Flashing footwear includes at least one light source located within and/or on footwear so as to be visible directly or indirectly with the light pipe such as heel of the footwear or garment. A power source, such as a battery, provides sufficient power to light the light source. An inertia responsive spring mass electrical switch develops pulses that are directly related to the amount of force to cause illumination flashes in direct response to the force applied to the spring mass switch. The switch is actuated by the condition of motion of the footwear or garment so as to change between open and closed positions and count the number of times the switch is actuated and further to display that count as a set of either a division, multiple, addition, and/or subtraction of the number of times the spring mass makes electrical contacts and to further flash illuminate any number of lights in sequence based on a set count of spring mass electrical contacts.

More particularly, the invention relates to a carbon black which imparts upon tire tread rubber improved treadwear, lower rolling resistance, lower heat buildup and improved tear resistance. The improved carbon black is in the N100 series and, when in rubber, combines the long tread wear and low heat buildup advantages N121 carbon black with the high tear resistance properties of N115 or N110. The improved carbon black has particular application to truck and bus steel cord radial tire treads, especially for use in on/off highway conditions, and for high performance passenger car tires.
Abstract: An optical waveguide system includes a generally planar waveguide 1 arranged so that light can be injected by a projector 2 into one edge at a range of out-of-plane angles. The waveguide 1 is tapered so that different out-of-plane angles, after being totally internally reflected for a certain distance, leave the waveguide at different respective points along the waveguide. This expands the image in the direction of propagation along the waveguide. Meanwhile the image is expanded transversely by a parallel-sided input waveguide 3. A large-area flat-panel display is thus created, or the planar waveguide can be used as a planar collimating light source or, using layers of controllable optical index, an optical switch.

Abstract: A fishing lure is formed of three principal parts, including a bullet-shaped nose section having a reduced diameter part toward the rear including an axial bore, a rear or plug section having a reduced diameter forward section which is a press fit into the axial bore, and a centrally positioned spinner consisting of an annular member surrounding said reduced diameter part and having highly reflective fins secured to its exterior surface. Grooves formed in the ends of the spinner serve as bearing races and bearings are located in the grooves to aid in causing the spinner to rotate freely when the lure is pulled through the water causing the fins to spin and flash in the light. The plug section has a collar of approximately the same diameter as the exterior surface of the spinner and a slightly reduced diameter toward the rear to accommodate a plastic streamer. The collar prevents direct impingement of the water against the forward edge of the streamer.
Abstract: A compact reusable bait station that can be used for either solid or liquid bait. The bait station has an outer wall that defines an inner bait chamber. The chamber, when sealed, prevents liquid bait inside the chamber from flowing out. The chamber has limited access from the outside to reduce evaporation, drying, and contamination of the liquid bait by preventing unnecessary exposure to the environment. Access to the outside is limited to access ports that are sized to allow access by an insect, but nothing larger. The access port is positioned above the level of the liquid bait to prevent leakage. The bait station is fabricated from reusable material, such as plastic, PVC, polyethylene, polypropylene, etc. and may be opened for cleaning and storage. Different configurations, such as triangular, rectangular, or tubular chambers may be used. Alternative embodiments provide ground attachment spikes which may be an integral part of the bait station or a removable attachment.
Abstract: A hand-held laser device that stimulates hair growth. The device provides distributed laser light to the scalp while simultaneously parting the user's hair to ensure that the laser light contacts the user's scalp. A unique beam splitting reflector splits a single laser beam to ensure that energy from the laser beam is evenly distributed. The reflector is mechanically aligned with the laser source and has a zigzag structure which mechanically deflects portions of the beam as it passes over the peaks of the reflector. The portions of the laser beam form a line of laser beams that project toward the user's scalp. Parallel rows of teeth are aligned with a central row of individual laser beams and part the user's hair to form furrows in the user's hair as the device is combed through the user's hair. The furrows create an unobstructed path for the laser beam to reach the scalp of the user.
Abstract: A device for collecting debris flowing in an artery downstream from a percutaneous coronary intervention includes a hollow guidewire, a double walled balloon connected to the guidewire, and a filter secured to the balloon and to the guidewire, all of which are inserted into the artery downstream of the intervention. Prior to the intervention, the double walled balloon is inflated to occlude the blood vessel except for the open area of the filter. Any debris flowing downstream from the intervention is caught in the filter. When the intervention is completed, the balloon is deflated causing it to collapse away from the vessel wall, permitting blood flow past itself and trapping any debris caught by the filter between itself and the guidewire. Multiple inflation and deflation cycles may be performed if multiple interventions are required upstream. The entire device can then be removed from the artery.
