Abstract: A high power electrical connector includes a plug and receptacle for use in a power transmission system. The plug includes a wire conductor attached to a mounting end and a circular contacting portion extending from a second end. The plug is configured to mate with a receptacle connector having a sleeve for engaging the circular extension and a mounting end for connection to a conductive wire. A contacting ring made from a braid provides a low resistance interface between the plug and receptacle minimizing the potential for heat buildup across the interface and minimizing electrical failure.

Abstract: A self-propelled construction road milling machine, includes a machine frame and a milling drum housing, in which a milling drum is arranged. The machine includes a drive unit with which the height of the scraper blade of a scraper device can be adjusted in relation to the milling drum. A control unit for the drive unit adjusts the height of the scraper blade and a measurement device measures the distance between the lower edge of the scraper blade and the milled material. The control unit is designed in such a way that the scraper blade is height-adjustable depending on the height of the milled material remaining in the milled track. The control unit ensures that, on the one hand, the milled material can come out of the milling drum housing unimpeded behind the milling drum in the direction of work and, on the other hand, that the milling drum housing is shut above the material that is coming out.

Abstract: A road milling machine includes a rear wheel or track mounted on a pivot arm such that the wheel or track is movable between a first outer end position projecting laterally relative to the machine frame, and a second inner end position which permits milling close to an edge. A travel drive of the rear wheel or track provides a driving force to move the wheel or track between the end positions.

Abstract: The invention concerns a dosing system for adjusting a dose volume of a fluid medium. The dosing system has a longitudinal center axis, a dosing sleeve with at least one communication opening, a dosing plunger, which can move axially in the dosing sleeve between a retracted and a depressed position to take up and dispense the medium through the communication opening, and a retraction limiting element to delimit a maximum axial retraction path of the dosing plunger. The retraction limiting element in at least one position can be axially fixed to the dosing plunger and can move radially to the longitudinal center axis between an inner position, axially fixed on the dosing plunger, and an outer position relative to the dosing plunger. In the inner position, it is completely inside the dosing sleeve. Furthermore, the dosing system has an end stop arranged on the dosing sleeve for interaction with the retraction limiting element in the retracted position of the dosing plunger.

Abstract: A self-propelled construction machine includes a machine frame and an operating drum arranged in a drum housing which is open downwards and is closed on both sides by an edge protector which is adjustable in height. A control assembly determines a reference value for the height of the ground surface relative to the machine frame on which the edge protector rests in a floating position, the height of the edge protector relative to the machine frame and the lowering speed of the edge protector. Furthermore, the control assembly is configured such that the height of the edge protector relative to the machine frame is determined at the point in time at which the lowering speed of the edge protector is less than a specified limit value. Preferred embodiments of the machine furthermore detect the edge protector sinking into the ground, and/or prevent the edge protector from digging into the ground.

Abstract: An in-line vacuum coating system includes a vacuum chamber, a coating source and a substrate carrier for holding tubular substrates, the carrier being displaceable using the vacuum chamber. A sure method of simply and securely coupling a fixed rotational drive unit to a carrier that can be displaced at a constant rate of speed in an in-line vacuum coating system is accomplished by a fixed splined shaft rotatably installed and connectable to a rotational drive unit, and a gearwheel that can be engaged with the splined shaft and that is rotatably mounted on the carrier. The gearwheel is longitudinally displaceable to a predefined extent in spring-loaded fashion in a direction opposite to the direction of travel of the carrier.
