Abstract: In one embodiment the semiconductor laser comprises a carrier and an edge-emitting laser diode which is mounted on the carrier and which comprises an active zone for generating a laser radiation and a facet with a radiation exit region. The semiconductor laser further comprises a protective cover, preferably a lens for collimation of the laser radiation. The protective cover is fastened to the facet and to a side surface of the carrier by means of an adhesive. A mean distance between a light entrance side of the protective cover and the facet is at most 60 ?m. The semiconductor laser is configured to be operated in a normal atmosphere without additional gas-tight encapsulation.

Abstract: The suspension means engages with a substantially horizontal portion of the pipework which is located at a geodetic altitude which is considerably different from that of the clamped portion of the pipework. In one embodiment, the suspension means has a pair of links each of which is pivotally connected to one of two spaced apart positions of the horizontal pipework portion and a pendulum to which the links are connected in common. The pendulum is pivotally mounted on a ceiling or the like. During expansion of the pipework, the suspension means allows the horizontal pipework portion to rise so as to relieve stressing in the pipework. In other embodiments, pairs of links may be used or a wire cable can be used to suspend the horizontal pipework portion.

Abstract: The thermal insulation is formed of a plurality of sheet metal elements which are aligned in interfitting manner to define a multiplicity of cells for disposition within or about a pipe or tube. The elements rest against the wall of the tube in a resilient manner and the cells defined by the elements retard heat transfer to and from the pipe wall.

Abstract: A cradle system for a steam generator having four flat diaphragm walls at right-angles to one another comprises a number of cradles. Each cradle has flexural members extending over a portion of the generator periphery which are connected to the diaphragm walls by pressure elements. The construction of the flexural members differs from one cradle to the next.The differences between the construction of successive cradles improve the resistance of the generator to earthquakes, in that forces acting diagonally on the generator are converted into bending loads, which are distributed over large regions of the diaphragm walls.

Abstract: The change-over means employs two three-way valves and two non-return valves for affecting a switch over in the sequence of flow through the four flow elements. Each three-way valve is constructed with a closure member which may only close one of the inlets of a pair of inlets of the valve or one of the outlets of a pair of outlets of the valve. The valves are arranged so as to switch the flow from a sequence of A-B-C-D to a sequence of A-C-B-D.

Abstract: The hand drive employs two coil springs between the sleeve of the coupling and the shaft to be turned. The hand wheel has a driver with a parallelepiped extension for abutting one or the other of the facing spring ends depending on the direction of rotation of the hand wheel. A brake is also used to restrain movement of the sleeve and limit the torque exerted on the sleeve by the hand wheel.

Abstract: The steam generator is provided with electrodes each of which is constructed with at least one longitudinally slotted tube into which a plate is placed in order to deflect incoming water from a central source tangentially into the tube. The deflecting plate is secured against one side of the slot and projects into the electrode tube to form an opening into the tube interior and has a free end within the tube. A trough collects excess water below the plate for delivery into the tube. The delivered water flows in a helical path within the tube while being heated to steam. The water discharge nozzles in the base of the electrode are partitioned so that water flows continuously and evenly from the electrode to prevent arcing below the electrode.
