Abstract: A vertical panic exit device is interchangeably mountable on either left-hand opening or right-hand opening doors and comprises a latch mechanism for engagement with a strike mounted to a doorjamb to alternately transition a door mounted to the jamb in a latched and unlatched configuration. A central portion includes a push bar; an action rod interlinked to said push bar such that a depression of the push bar causes the action rod to be translated in a direction orthogonal to the push bar, and a center case mechanism movable between a latched and an unlatched position. The center case mechanism comprises a housing, and a main link carriage horizontally slidably mounted within the housing. The main link carriage is linked to and is acted upon by the action rod for translation between the latched and unlatched position. An actuator link has a first end pivotally attached to the main link carriage. A pivoting member is pivotally mounted to the housing and has first and second pivotal attach points.

Abstract: A novel power block distribution block kit is disclosed. The blocks may use MAXI or AUG, or other types of commercially available type fuses. The present invention discloses a variably fusable power distribution block kit that permits custom configuration of the fuse to circuit relationships on a common base, and with a common cover to achieve higher circuit ratings with the same device, fuses, and component parts.

Abstract: An excavating machine, representatively a tracked excavator has a boom stick portion on which both an excavating bucket and a hydraulic breaker are mounted for hydraulically driven pivotal movement between first and second limit positions. With the breaker in its first limit position, the bucket may be swung away from its first limit position and used independently of the breaker for digging operations. Similarly, with the bucket in its first limit position, the breaker may be swung away from its first limit position and used independently of the breaker for refusal material-breaking operations. Thus, the same excavating machine may be used for both digging and breaking operations without the previous necessity of changing out excavating apparatus on the boom stick. A specially designed electrical and hydraulic circuit is provided which permits the positional control of both the bucket and the breaker with the same control device typically used to control the pivotal orientation Of an excavating bucket.

Abstract: A modular cart comprises a load carrying frame and a wheeled carriage supporting the load-carrying frame. The carriage includes a front carriage assembly pivotally coupled to a front of the frame and a rear carriage assembly pivotally coupled to a rear of the frame. The front and the rear carriage assemblies are substantially identical. Each carriage assembly comprises an axle pivotally coupled at a vertical midpoint axis to the load-carrying frame. The axle is pivotal about the vertical midpoint axis and is selectable between a first position pivotally fixed with respect to the load carrying frame and a second position freely pivotal about the axis. A caster wheel assembly is attached to each of the ends of the axle. The caster wheel assembly is pivotal about a vertical end axis and is selectable between a third position pivotally fixed with respect to the axle and a fourth position freely pivotal about the vertical end axis.

Abstract: A mixture of hydrocarbons with particulate rock and/or soil that is incapable of sustaining growth of erosion retarding plants can be converted to soil that is capable of sustaining such plant growth by blending the mixture with particulate biomass, and/or with particulate carbonates, hydroxides, and/or oxides of calcium and/or magnesium to produce a compostable aggregate and then exposing suitable piles of the compostable aggregate to the natural atmosphere for a sufficient time to cause the conversion of the aggregate to fertile soil.

Abstract: A landscape-edging device is disclosed which may be used to segregate dissimilar landscaping schemes by positioning the device into the soil. The landscape edging is made of flexible strips, designed for continuous end-to-end attachment. The edging is attached to the soil by stakes. The edging system is designed so that stakes are removably attached to the edging portion of the device. By this attachment, the stakes can be conveniently and cost effectively manufactured and shipped together with the edging portion. Stiffening ribs on the stakes increase the strength of the stakes so that they may be made from the same material and thickness as the edging portion.

Abstract: A method and system for remote assistance and review of a technician or multiple technicians, in real time, working with equipment of various complexity. A technician or multiple technicians at a remote location are coupled by a wireless means to an advisor at a local station, so that the advisor may view and hear the same stimuli as the technician, that the advisor and technician may communicate. The technician has limited training or otherwise in need of support, and may be a field engineer, technician or maintenance personnel. The advisor has extensive training and able to provide technical support, and generally has extended and specialized knowledge with regard to the remote apparatus, and may be a technical expert on the remote apparatus. The technician may comprise an individual or group with technical training and knowledge, but lacking managerial or other authority, while the advisor comprises an individual or group with such authority.

Abstract: The present disclosure provides a secure yet easily adjustable link design for use in interconnected link jewelry and watches. A link for a bracelet is disclosed that allows for easy adjustment in the length of the bracelet, utilizing a bar and spring system. To remove a link from the bracelet, the links must be at approximately a right angle, force must be applied outwardly to the link with the spring from which a bar is to be removed, and the links easily separate. Similarly to couple links, the links must be at approximately a right angle. When the links are at approximately a right angle, the bar of the first link can enter the spring of the second link. When the links are at any other angle, the bar is secured in the spring and cannot be removed or dislodged. The disclosed bar and spring system allows for a secure yet easily adjustable link system.

Abstract: The panic exit device includes several features which improve its ease of use and operability over earlier devices including: (1) an improved latch deadlocking mechanism; (2) an improved latch to pad mechanism; (3) a pad lock down feature; (4) an improved universal mounting plate and easily mounted strike; and (5) a vertical rod-bottom bolt deadlocking mechanism in its center case. The latch deadlocking mechanism includes a deadlock link, which in the event of a fire, will block the movement of the latch bolt.

Abstract: A tool for expanding a hole size while drilling tool is disclosed. The tool utilizes a mechanically actuated mandrel and extendable cutting lugs designed in a configuration with fewer moving parts than previous designs. The cutting lugs have multiple cutting elements attached. The cutting lugs are driven between two cylindrical diameter surfaces to achieve a large differential between the retracted and extended positions of the tool, and to provide sufficient stability to allow the tool to be used in the extended position while drilling forward. The lugs are internally assembled and tapered to closely match the slots in the body of the tool for additional stability and to prevent complete passage through the tool for prevention of catastrophic failure. The tool has a locking mechanism to allow the tool to remain in the extended position when the weight is removed from the tool.
