Abstract: This invention involves a fiberglass composition containing the following components: SiO2, Al2O3, CaO, MgO, B2O3, F2, TiO2, K2O, Na2O, Fe2O3 and SO3. The weight percentage of each of the components are as follows: SiO2 58˜65%, CaO 20˜26%, Al2O3 9˜17%, MgO 0.5˜1%, B2O3 0˜5%, F2 0˜1%, TiO2 0.1˜1%, K2O+Na2O 0˜0.8%, Fe2O3 0.1˜0.5%, SO3 0˜0.6%. The ternary system, SiO2—Al2O3—CaO, is basis of the fiberglass composition in this invention, which also has low quantities of MgO and B2O3. In addition, the total amount of alkaline earth oxide and the proportional relationship between MgO and CaO are rationally designed, which helps to improve the mechanical strength, heat resistance, and chemical stability of the glass. It also has excellent manufacturing performance. Moreover, the raw materials of the fiberglass composition in this invention are low in cost, and the invention meets environmental protection requirements.

Abstract: Circuits and methods for transmission of digital data between two or more devices via powerline particularly suited for use in high attenuation, high noise commercial/industrial powerline environments, including transmission of pulses generated by a capacitor charged in the positive half cycle of the sine wave and discharged during the negative half-cycle, placing the pulse at one of two predetermined signal timing positions related to zero voltage crossing points or to previously transmitted pulses so that the pulses are substantially in the powerline temporal quiet zone near zero crossing and so that the powerline voltage at the time of the pulse is additive to the capacitor voltage.

Abstract: A method for installing a modular fireplace mantel surrounding a fireplace in a wall utilizing a unique leaf spring bracket. The leaf spring bracket for a modular fireplace mantel comprises a base plate, an upper lip, a lower lip, a left side lip and a right side lip attached to said base, said four lips defining a recess, a slot cut in the meeting edges of the base plate and the upper and lower lips, an extension attached to each of said left side and right side lips, each extension having one or more holes through which connectors may pass, an arcuate shaped leaf spring adapted to fit into said recess, both ends of said leaf spring having a reverse arc adapted to fit into said slots.

Abstract: A modern jet engine inlet protection system that protects against large birds and operates autonomously, that is dormant in routine aircraft operations, that automatically actuates its protective device(s) only at the immediate point of need, then returning it (them) to a non-interfering position, including a RADAR system and a LIDAR system which detect birds entering the intended flight path of the aircraft, and fast computer-implemented computational algorithms that track and identify those from the detected set that are (1) projected to enter a zone which would lead to ingestion by the engine, and (2) of a size large enough that they would seriously damage the engine if ingested; that includes defensive mechanisms housed in the engine nacelle cowling or center hub, or in the fuselage structure that are instantaneously actuated shortly before arriving at the point of impact to shield, deflect, reduce the size of the approaching bird to an acceptable mass, or destroy it, and, that after the ingestion threat

Abstract: A stand alone flat bed scanner including a CPU, a removable storage medium, a control system displaying digital image and controls for controlling the mode of operation, degree of resolution, related parameters associated with generating, storing and displaying digital data. Ports for printers, accessories and other peripherals, an internal hard drive, and software adapted to display images directly on a television screen, and/or to display images projected from an LCD projector upon a screen, including battery, and a pivotal handle for portable use in environments not having an external power supply. One embodiment, not including an incorporated flat bed scanner function, adapted to receive image data from a conventional scanner unit.

Abstract: A mounting apparatus for use with a parameter measuring device includes a stem extending from an outer casing of the parameter measuring device, where the stem includes an internally threaded opening. A mounting plate having an integral barrel formed thereon cooperates with the measuring device wherein the mounting plate abuts the outer casing and the integral barrel surrounds the stem. A mounting bar is secured to a distal end of the integral barrel wherein the mounting bar serves to attach the measuring device to an external surface. Finally, a threaded fastener is threadedly received within the internally threaded opening of the stem for securing the mounting bar and the mounting plate to the measuring device.

Abstract: A less lethal projectile to be fired from a launcher comprising a body having a concentric cavity to hold a fluid payload, a nose cap attached to the body, said nose cap having a plurality of slits therein, which will spread open upon impact, allowing the fluid to escape.

Abstract: The present invention relates to a badge where it is possible to select the attachment position of attachment means such as a detachable pin while confirming orientation of a representation attached to a badge body, and a badge manufacturing device that is lightweight and robust, and that can be operated even at an unstable location and in a small space. A badge 200 comprises a badge body 200a having a front cover 201, a sheet body 213 mounted on a front surface plate 202 of the front cover 201, and a rear cover 205 for engaging with the front cover 201 to sandwich a peripheral edge of the sheet body 213 between the rear cover peripheral edge 209 and the front cover peripheral edge 203, and mounting means 229, 237 for linking to the badge body 200a by selecting a direction to cross the rear surface plate 206 of the badge body 200a (X direction, Y direction or Z direction).

Abstract: A yoga mat that may be rolled up tightly and then held closed by straps, which wrap around and encircle the rolled up mat. The straps are affixed to the mat by the ends thereof being sewn to the edge of mat under an attachment strip, which fits along one entire edge of the mat. A shoulder strap is also attached under the attachment strip between the two straps, so that the mat can be carried over the shoulder with both hands and arms free.
