A coin handling apparatus having: a first coin position; a second coin position; and a pipe for transporting coins from the first to the second coin position. The pipe is jointed and has a rigid, elongate element having a straight, elongate portion and a curved portion at a first end of the straight, elongate portion. The pipe further includes a rigid, curved element. The curved portion and the curved element are connected to define a continuous passageway through the curved element and the elongate element. The curved element, at least before mounting of the pipe in the coin handling apparatus, is rotatable in relation to the elongate element, such that an angle between a first opening of the curved element and a direction extending along the straight elongate portion is variable.

A quick connect fluid connector is directly connected to a fluid port of a fluid manifold using a quick connect fluid connector swivel that is configured to permit rotational and/or longitudinal movement of the quick connect fluid connector relative to the fluid port. The relative axial and/or rotational movements provided by the swivel eliminates the need for a fluid hose to be used in the fluid path between the quick connect fluid connector and the fluid port.

A recreational vehicle waste disposal system is provided. The waste disposal system includes a conduit assembly having a proximal end connected to the sewer outlet of a sanitation unit, wherein the distal end of the waste disposal system is rotatable relative to and extendable from the proximal end. A user may rotate the conduit assembly between an operable position and a stored position directly under the RV's sanitation unit. The downstream portion defines an extension arrangement of a plurality of threaded conduit sections that may be optionally connected to allow an extended length to store two waste hoses if desired.

A coupler, adapted for being assembled and connected with a water sprayer, includes a sleeve and a coupling member adapted for being assembled and connected with the water sprayer. The coupling member and the sleeve are sleeved with each other and respectively have a first corresponding end and a second corresponding end which correspond to each other. The first corresponding end and the second corresponding end are adapted to be engaged with each other, so that the sleeve and the coupling member are capable of being mutually locked and into a non-rotatable state through the engagement and rotation meshing operation. The sleeve can be disengaged with the coupling member through axially moving the sleeve so that the sleeve is allowed to be axially rotatable.

The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.

A backflow prevention assembly is configurable with varying lay-lengths and orientations. The assembly includes coupling assemblies and valve bodies that adjust in length and/or rotation to allow for the varying lay-lengths and orientations of the backflow prevention valves and assemblies with and without certification. A coupling assembly is connected to a backflow prevention valve and includes an outer sleeve and an inner sleeve that is slidingly received within the outer sleeve. The lay-length is adjusted by slidably moving the inner and outer sleeves with respect to one another.

A coupling for conveying a fluid between a stationary part and a rotatable part having confronting ports centered on a rotation axis of the rotatable part has an axially extending tube fixed in the port of one of the parts and extending toward the port of the other of the parts and a control element axially slidable on the tube. The one part, the tube, and the control element form an annular chamber around the tube pressurizable for axially shifting the control element. A first slide ring is connected to the control element and carries a seal ring turned toward the port of the other part, and a second ring on the other part at the port thereof axially bears on the first slide ring so that pressurization of chamber presses the slide rings axially against each other.

A magnetic filter 10 includes first and second separation chambers 10, 12. The separation chambers 10, 12 each have an inlet and an outlet, and the separation chambers 10, 12 are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement 28 connects both inlets to a single inlet pipe, and an outlet port arrangement 30 connects both outlets to a single outlet pipe.

A coupling for an irrigation system may have a first member and a second member, each of which has threads that engage a threaded fitting of an adjacent component. The first member may have a shank and a flange that has a greater exterior dimension than the shank. The flange may have a first locking extension. The second member may have a bore that receives the shank such that the second member is slidable along the base member between a locked configuration in which rotation of the second member about the centerline induces rotation of the base member about the centerline, and an unlocked configuration, in which the second member is rotatable about the centerline independently of rotation of the base member. The second member may further have a first recess that receives the first locking extension in the locked configuration.

A tubular connection system includes a connector coupled to a tubular segment, the connector having a first bore with a first bore diameter and a mating connector coupled to the connector, the mating connector having a second bore with a second bore diameter. The connector includes a plurality of connector lugs extending into the first bore. The connector also includes a plurality of gaps, respective gaps of the plurality of gaps are arranged between adjacent connector lugs of the plurality of connector lugs in a first alternating pattern. The plurality of connectors lugs are arranged in connector lug rows. The mating connector includes a plurality of mating lugs radially outward. The mating connector also includes a plurality of openings, respective openings of the plurality of openings are arranged between adjacent mating lugs of the plurality of mating lugs. The plurality of mating lugs are arranged in mating lug rows.
