Abstract: Embodiments of a polyethylene (“PE”) pipe servicing system of this disclosure may include a fusible PE fitting (F) providing a branch connection to a PE pipeline section or run (P), a valve (10) connected to the fitting and including quick connect/disconnect means, and a machine connectable to the valve including complementary quick connect/disconnect means. The quick connect means provide for full scope of operation, including cleaning, fusion, cool down, hot tap, plugging, and completion. No squeezing is used. The quick connect/disconnect means may include a first portion 20 of a cam profile and a second portion 40 of the cam profile complementary to that of the first. The machine may be a drilling or hot tapping machine (30T), a plugging machine (30P), or a completion machine (30C), and their associated tools. The valve and machine are more lightweight and faster and easier to use than the prior art.

Abstract: Control device for activating/deactivating functions, comprising a supporting plate comprising a contact surface providing electrical contacts, a control member for selecting a function with the actuation of a switching means, the control member mounted rotatably about an axis of rotation and pivotably about a pivot axis separate from the axis of rotation, rotation and pivoting of the control member facilitating selection of a function and confirmation of the selected function. The control member may be associated with an actuating lever, of which one end comprises the axis of rotation, and of which the other end is mounted pivotably about the pivot axis, the lever being displaceable between a rest position and at least one active position in which at least one electrical switching means on the supporting plate is actuated for purposes of confirming a function, the axis of rotation and the pivot axis extending in separate extension planes.

Abstract: Control device for activating/deactivating functions, particularly of an automobile vehicle, comprising: a housing in which is produced a supporting plate comprising a contact surface, making electrical contacts, a control member selecting and confirming a function with the actuation of a switching means, the control member being mounted rotatably on an axis of rotation and pivotably about a pivot axis P separate from the axis of rotation R, rotation and pivoting of the control member facilitating selection of a function and confirmation of the selected function.

Abstract: A system for fixing one of two plugs (3, 4) of an electrical connector to a mechanical device (1), the one plug (4) being designed to be connected thereto in a detachable manner, the other plug (3) being attached to an assembly (2) to which the device (1) has just been coupled mechanically along an axis parallel to the axis of the electrical coupling, characterized in that it includes means for assembling/disassembling the plug (4) to and from the said mechanical device (1), the assembly/disassembly being carried out parallel to the coupling axes, assembly being made simply by clipping, while disassembly is carried out simply by pulling.
