An agricultural implement including a frame with a main frame section and at least one wing frame section such that the agricultural implement is configured for transitioning in between a work position and a transport position, at least one conveyance line, and at least one coupling device. The at least one coupling device includes a first coupling member attached to the first line portion and a second coupling member movably connected to the first coupling member and attached to the second line portion such that the at least one coupling device couples the first line portion and the second line portion of the at least one conveyance line in the work position and uncouples the first line portion and the second line portion of the at least one conveyance line in the transport position.

A pipe element coupler includes a plurality of coupling members, a gasket disposed in the coupling members and a fastening element. Each of the coupling members includes two engaging keys at two coupling end portions thereof each having an engaging surface that has varying radiuses of curvature. The fastening element is coupled at the coupling members, wherein the pipe element coupler is adapted for being preassembled on the two pipe elements to align the engaging keys with the corresponding grooves of the pipe elements. When the fastening element is operated to fasten the to coupling members together, each of the engaging surfaces is deformed to change the varying radiuses of curvature, so as to substantially match a radius of curvature of the groove circumference at the bottom of the groove of the pipe element.

Disclosed are systems and methods for connecting a hydraulic fracturing fluid source to various wells at a given well site. In general, use of disclosed systems and methods provide for repositioning (refocusing) the hydraulic fracturing operation amongst multiple wells may be achieved. In one example, a system to reroute fracturing fluid from a source to various wells at a well site may be provided. The use of adapters and quick clamp connections allow hydraulic fracturing fluid to be rerouted between various wells in a manner to decrease the cost and reduce hazards associated with changing hydraulic fracturing locations. Modular components of the system (and an overall modular design of the system itself) may allow a centralized manifold to be relocated to various locations at one or more well sites.

An exhaust lining for an exhaust system of a motor vehicle has a first connecting element clamped between a first and second pipe. The first pipe forms a tailpipe. The second pipe forms a tailpipe cover. The tailpipe cover has a tubular inner part held on by means of the first connecting element which clings onto the first pipe via by means of a lever mechanism. A load arm of the lever mechanism, having the distance A, is shorter than an effort arm, having the distance B. The length of the effort arm is precisely defined, because the end of the effort arm lies against the first pipe via a punctiform contact area. A first contact surface of a clamping spring is designed offset from the longitudinal extent of a main body of the first connecting element to save space in the longitudinal direction of the main body.

An exhaust tailpipe mounting system for mounting on an exhaust pipe end includes a tailpipe and a ring member attached to the tailpipe. At least three spring elements are attached to the ring member, wherein each spring element extends generally along a longitudinal axis and is bent into a wave shape. Each spring element has a proximal end opposite a distal end, where the proximal end is attached to the ring member and the distal end has at least one pointed end configured to grip into an outer surface of the exhaust pipe end. Each spring element has a first, second, third, fourth, fifth, sixth and seventh bend zone starting from the proximal end and respectively going to the distal end. The at least one pointed end of is angled at an angle of 75 to 85 in relation to the longitudinal axis of the spring elements.

A quick-connect fitting includes a polymeric first connector in fluid communication with a first component, and a polymeric second connector in fluid communication with a second component. The first connector is either a male fitting or a female fitting, and the other of the male fitting and female fitting is the second connector. The female fitting includes a longitudinal cylindrical cavity having therein a retaining ring retaining an o-ring, and the male fitting includes a cylindrical body and a tubular sealing element extending longitudinally therefrom positionable within the polymeric female fitting and o-ring in sealing engagement. The quick connect fitting includes a clip pivotably connected to the second connector moving between a first position connecting the female fitting to the male fitting when the male fitting is positioned within the female fitting and a second position in which the male fitting is removable from the female fitting.

An assembly/disassembly apparatus for flanged mechanical device comprising: a main body provided with a rear abutment sector having at least a seat; a coupling pin housed in part in the seat and extending from the seat in a first direction; a grabbing device coupled to said main body; an engagement mechanism provided at least by a first and a second retaining arm, said first and second retaining arms being movable together at least between a first and a second positions, in which, in said first position the first retaining arm faces the rear abutment sector while in said second position the second retaining arm faces the rear abutment sector.
