The invention provides an optical short-circuit insert for accommodation in a plug housing, with a plug region with two mutually parallel optical fiber ends of an optical fiber portion. A curved region of the optical fiber portion, intermediate optical fiber ends, is guided in an arc of 180 degrees. The optical fiber portion has a curved portion of a fiber consisting of multi-component glass with cladding or of a multi-conductor glass fiber with cladding, which is enveloped in a plastic carrier. An optical short-circuit plug with a plug housing enveloping a plug and a short-circuit insert capable of being pushed into it is also provided.
摘要:
An apparatus for the adjustment of the valve control of a reciprocating piston internal combustion engine with a cam shaft driven from the crankshaft by an endless, flexible transmission member, in which the cam shaft and a valve control adjustment device are brought into engagement with each other by a control member arranged transversely to the plane of the separating surface of a control space housing with a loosened threaded connection; the driving gear is nonrotatably fixed with respect to the cam shaft by way of the transmission member drivingly connected with the crankshaft and tensioned by a tensioning roller while the crankshaft is nonrotatably fixed in the top dead center position with respect to the crankcase by a locking pin.

A console for holding nautical indicators has a back wall, opposite, generally parallel side walls, top and bottom walls and an open front for receiving an indicator. Preformed openings are in the side walls, closed by a frangible membrane, for receiving fasteners through aligned openings in adjacent side walls of two consoles placed side-by-side to secure the two consoles together as a unit. Each console is configured to support and enclose a single indicator, and a plurality of consoles with associated indicators may be readily secured together to form a multi-indicator console.

An indicating instrument, particularly adapted for use with watercraft, with a cup-shaped casing of plastic material. The casing holds a measuring instrument with a dial. The front end of the casing is shut by a window shield and enveloped by a front frame.
摘要:
A piston-type internal-combustion engine having deactivatable, mechanically actuated cylinder valves that are respectively actuated by at least one camshaft via a roller drag lever (5) comprising two partial levers (5.1, 5.2) that are hinged to one another via an articulated shaft (6), on which the roller (7) associated with a cam (8) of the camshaft is rotatably seated. A locking mechanism (13) is provided to selectively couple or decouple the two partial levers (5.1, 5.2) to activate or deactivate the force transmission between the camshaft and the cylinder valve. The free end 5.11 of one partial lever (5.1) is supported on the cylinder valve (2), and the free end 5.21 of the other partial lever (5.2) is supported on the engine block (11).
