Abstract: Synthetic aggregate that includes a plurality of agglomerations. Each of the plurality of agglomerations may include a core; and a shell material disposed on the core. According to various embodiments, the construction aggregate may be non-flammable. According to various embodiments, at least one agglomeration of the plurality of agglomerations may have a plurality of cores. The core may include coal, a coal byproduct, and combinations thereof. According to various embodiments, the coal may be a type such as lignite, sub-bituminous, bituminous, and anthracite. The coal byproduct may be fly ash, bottom ash, shale coal, or coal gob.

Abstract: Described herein are guide sleeves and kits for guide sleeves having a plurality of modules. Each module may have an axial extending main body having first and second axially spaced apart opposed ends and an outer sidewall. The modules may also have an axially extending internal opening extending between the first and second axially spaced apart opposed ends for receiving a flexible linear member. Internal rollers may be associated with the internal opening so that as the flexible linear member travels axially through the internal opening, the internal rollers rotate relative to the flexible linear member. When the modules are connected, a first module may be axially moveable with respect to a second module and the guide sleeve may be bendable.

Abstract: A coating composition and method of making a scratch resistant UV blocking glass coating is described. The composition can include an aqueous colloidal silica. a bifunctional silanol coupling agent, tetraethylorthosilicate (TEOS), a UV absorber, and a water miscible solvent selected from glycol ethers, alkanols, keto alcohols, and combinations thereof. The molar ratio of the bi-functional silanol to TEOS is selected to provide scratch resistance coupled with water resistance.

Abstract: A resin for making abrasion and scratch resistant UV blocking glass coating. The resin can include an inorganic polysiloxane polymer matrix formed from water-based colloidal silica and tetraethylorthosilicate (TEOS). The resin also can include a bi-functional silanol coupling agent coupled to the inorganic polysiloxane polymer matrix. The resin further can include a UV absorber conjugated to the bi-functional silanol coupling agent. The resin also can include a solvent that is compatible with the colloidal silica, TEOS, bi-functional silanol agent, and UV absorber.

Abstract: A rotary drag bit for drilling a subterranean formation includes a plurality of support elements affixed to the bit body, each forming at least a portion of a cutting element pocket. Each of a plurality of cutting elements has a substantially cylindrical body and is at least partially disposed within a cutter pocket. At least a portion of the substantially cylindrical body of each cutting element is directly secured to at least a portion of a substantially arcuate surface of the bit body. At least a portion of a substantially planar surface of each cutting element matingly engages at least a portion of a substantially planar surface of a support element.

Abstract: A motorized, retractable antenna system for a recreational or similar vehicle. The antenna system includes an antenna head pivotally mounted to a support arrangement for rotation about a substantially horizontal axis between retracted and raised position. The support arrangement and attached antenna head in turn are then mounted to a stationary base assembly for rotation about a substantially vertical axis. A locking mechanism is provided to secure the retracted antenna head and support arrangement in predetermined positions relative to the base assembly and vehicle and to aid in the control of the raising, adjusting, and lowering of the antenna head.

Abstract: An air bag module for a motor vehicle. The air bag module includes a housing, an air bag, an inflator, and a tear panel having a weakened area. The tear panel directs deployment of the air bag away from a vehicle occupant before the weakened area tears.

Abstract: A cutting element retention apparatus wherein a support element forms at least a portion of the cutting element pocket is disclosed. A steel body rotary drill bit carrying at least one generally cylindrical cutting element within a cutting element pocket wherein a support element forms at least a portion of the cutting element pocket is also disclosed. A support element may form at least the substantially planar surface of the cutting element pocket configured to matingly engage at least a portion of a substantially planar surface of a generally cylindrical cutting element distal to the cutting face thereof. Alternatively, a support element may form substantially the entire cutting element pocket. The support element may be press-fit, shrink-fit, brazed, welded, or otherwise affixed within the steel body rotary drill bit. Methods of manufacture and repair of steel body rotary drill bits are also disclosed.
