A base portion of the linear motion unit is fixed to a mount. A base portion of the rotation unit is fixed to an output portion of the linear motion unit. The end effector is mounted to an output portion of the rotation unit.
A pin array release and capture chamber system includes a chamber assembly having two parallel plates of pin arrays from which a plurality of pins extends and retract vertically opposite each other so as to release and capture a space vehicle. The pin arrays are separated from each other by a space having two vertical and two horizontal sides, and the space is sized so as to receive the space vehicle. Each pin arrays may be housed in a pin array chamber enclosure. The chamber assembly may be attached to a moving object, such as a host space vessel.
A launch includes a frame including a platform defining a slot designed to slideably receive a rudder of a fixed-wing unmanned aerial vehicle. The launch includes two drive wheels rotatably supported by the frame and defining a space between each other. The space is open to the slot and designed to receive the rudder. The launch includes at least one variable speed drive wheel motor supported by the frame and operatively engaged with the drive wheels.
Ribs for working an aircraft component having an aircraft component surface, fixtures for the same, and methods for the same, are provided herein. The rib includes a rib surface configured to receive the aircraft component and to be in abutting contact with at least a portion of the aircraft component surface. The rib further includes an extension extending away from the rib and configured to couple to a worksurface. Orientation of the rib is configured to be adjustable relative to the worksurface for improving working of the aircraft component. The fixture includes a mount defining an aperture and configured to be coupled to the worksurface and the rib. The method includes providing the fixture including the rib. The method further includes coupling the extension to a worksurface. The method further includes disposing the aircraft component on the rib surface.
A replacement vibration absorbing device for replacing a wear wrap on a flexbeam includes a sleeve having a plurality of layers of vibration absorbing material, wherein an edge of the sleeve is cut so that the sleeve may be installed around a generally central portion of a flexbeam.
Embodiments described herein generally relate to methods and systems for preparing compositions, such as those comprising hydrogen gas. In some embodiments, the method comprises injecting liquid hydrogen and/or a liquid noble gas(es) into another liquid (e.g., a composition) such that at least a portion of the liquid hydrogen and/or liquid noble gas(es) can change phase into a gaseous phase. The liquid noble gas may be, for example, liquid xenon, liquid argon, or the like. In some embodiments, the gaseous hydrogen and/or the liquid noble gas(es) may infuse with the composition (e.g., such that at least a portion of the hydrogen gas and/or noble gas(es) is dissolved within the composition). Such compositions comprising hydrogen gas and/or noble gas(es) may be useful, for example, for the treatment of animal and human diseases, for improvement in athletic performance, for the enhancement of the overall health of a subject, or the like. Such compositions and/or liquids described herein may be administered (e.g., orally) to a subject, e.g., drunk by a subject.
An apparatus includes an infeed conveyor configured to convey food products from an infeed position to a free end of the infeed conveyor. Means are provided for detecting positions of the food products on the infeed conveyor, and a tray feeding conveyor is configured to convey empty trays to a tray filling position where food products are released from the free-end of the infeed conveyor and into the trays. Means are provided for detecting positions of empty trays on the tray feeding conveyor. A moving means adjusts the position of the free end of the infeed conveyor, and a control unit controls the moving means by utilizing the detected positions of the food products and the detected positions of the empty trays as operation parameters in adjusting the position of the free end when releasing the food products from the releasing end of the infeed conveyor and into the trays.
A utensil wrapping apparatus including belt rollers, conveyor belts, a bracket assembly, napkin folders, fold actuators, and a rolling station is provided. The conveyor belts wound around the belt rollers accommodate and convey a napkin with one or more utensils placed thereon from an entry end to a release end of the conveyor belts. The bracket assembly folds a leading corner of the napkin over the utensils. The napkin folders, actuated by the fold actuators, fold opposing corners of the napkin around the utensils. The rolling station receives and initiates rolling and tucking of the napkin folded around the utensils. A set of rolling belts in the rolling station moving in a direction counter to movement of the conveyor belts rolls the napkin folded around the utensils and facilitates conveyance of the rolled napkin with the utensils over the conveyor belts to a release end of the conveyor belts.
A method of individually packaging a single-use disposable diaper for use in intimate absorption of body fluid includes compressing a single-use disposable diaper for use in intimate absorption of body fluid from a first condition to a second, compressed condition, and retaining the single-use disposable diaper in the second, compressed condition with a pressure differential that acts upon a substantially flexible, substantially air impermeable material to maintain the single-use disposable diaper in the compressed condition. The pressure differential is created by locating the single-use disposable diaper in an interior space of a substantially air impermeable, substantially flexible material, creating a negative pressure within the interior space, and hermetically sealing the single-use disposable diaper at the negative pressure within the flexible material. The single-use disposable diaper is the only single-use disposable diaper contained within the hermetically sealed substantially air impermeable, substantially flexible material.
A vacuum sealing device includes a sealing base and a sealing cover arranged on the sealing base, the sealing base is also provided with a push-pull assembly for pushing and pulling the sealing cover; the push-pull assembly includes two piston cylinders disposed at both ends of the sealing base, a piston assembly disposed within the piston cylinder and pivoted to said sealing cover, and a pneumatic assembly disposed in the sealing base and pushed the piston assembly to reciprocate within the piston cylinder. The vacuum sealing device solves the trouble that the original mechanical structure needs to close and open the seal cover manually, thus realizing automatically vacuum sealing functions, it releases hands and greatly increases the convenience of operation.
