Abstract: A cover that extends over a fastener and methods of installing the cover over the fastener. The cover includes an open end positioned at a member from which the fastener extends. The cover also includes a closed end that extends over the fastener and shields the fastener from the exterior environment that can be combustible. A plurality of holes extend through the cover from the interior space to an exterior environment external to the cap.

Abstract: A cover that extends over a fastener and methods of installing the cover over the fastener. The cover includes an open end positioned at a member from which the fastener extends. The cover also includes a closed end that extends over the fastener and shields the fastener from the exterior environment that can be combustible. The cover includes an outer shell with one or more windows. An inner shell is positioned within the outer shell. The inner shell includes one or more windows that are offset from the windows of the outer shell. One or more flow paths extend through the windows for gas, liquid, and/or some particles to flow through the cover while removing the thermal and/or kinetic energy that may ignite the combustible exterior environment.

Abstract: Process for making purified hydrogen cyanide. The process includes feeding a reaction product including HCN, water, and organonitriles to a separation vessel; taking a liquid slip stream of HCN, water and organonitriles from the separation vessel; and feeding the liquid slipstream into a sidestream stripper to purge nitriles from the HCN reaction product.

Abstract: A full body exercise apparatus and method allowing for a full body workout utilizing all major muscle groups. The apparatus generally consists of a plurality of ropes allowing the user to pull the handles providing for arm resistance as well as leg and core resistance in a downward and upward motion by the user. The result is a full body workout after a series of repetitions using the apparatus.

Abstract: A transportation system for transporting construction equipment that rides on a driven element during ordinary operation. The transportation system relieves a portion or all of the operational weight of the construction equipment from the driven element during transportation of the construction equipment. The transportation system includes a frame, upwardly extending supports that support a chassis of the construction equipment, and a lifting device interface for loading and unloading the transportation system with respect to a vehicle or trailer for transporting the construction equipment.

Abstract: A transportation rack for construction equipment is provided. The transportation rack includes a pad for supporting a hard, smooth wheel of the concrete equipment. The pad absorbs dynamic loads on the construction equipment during transportation to avoid flat spots developing on the hard, smooth wheel. The transportation rack also includes a rigid guard to protect a precisely aligned element of the equipment, and a rigid bar extending across a portion of the construction equipment to hold it down or apply a containment load to hold the equipment against the pad.

Abstract: Medical devices having one or more cutting elements are disclosed. In some embodiments, a medical device includes an elongated catheter configured to be inserted into a body, and a cutting element carried by the catheter. The cutting element has an alloy including from about 12% to about 16% by weight of chromium, from about 0.5% to about 5% by weight of molybdenum, and iron. The alloy has a martensitic phase.

Abstract: A tensioning apparatus for tensioning a screen in a vibrating screen separator of the type having a box structure defined by two opposing spaced-apart upright side walls separated by at least one screen bed support structure. Included is an actuator support mounted to an exterior surface of a side wall of a box structure for pivotally securing the stationary end of an actuator thereto. The actuator includes a movable end that is cyclically movable from a first releasing position adjacent the sidewall, to a second engaging position, transversely spaced apart from the side wall, responsive to a track follower moving along a track inclined transversely to the side wall of the box. A clamp rail assembly is fixed to the movable end of the actuator to engage and tension a screen responsive to transverse movement of the movable end of the actuator.

Abstract: Embodiments of the disclosed technology comprise a combination refrigeration and combustion system including a tank that holds liquefied gas, an expansion valve in fluid connection with the tank, and a sealable chamber housing an evaporator, with the evaporator in fluid connection with the expansion valve. The system is configured for expulsion of the liquefied gas from the tank into the expansion valve. The expulsion takes place in at least one pulse over part of a defined time interval. After an expulsion of gas, the liquefied gas expands into gaseous form in the evaporator, allowing for continuous combustion of the gas in gaseous form.

Abstract: The interface uses a combination of controls that retain essentially the same function throughout all modes and features and controls that vary based on the active mode or feature. The interface also includes a display. The display can provide text information, graphic information or a combination of text and graphics. The arrangement of the mode controls, the soft controls and the display is designed to facilitate the user's interaction with the system. The system provides some redundant controls so that the user can select the control that is most convenient or intuitive for that user.
