Abstract: The invention relates to a horizontal filter with a filter housing, in which an arrangement of superimposed, spaced filter elements is contained, and with distributor means supplying liquid to be filtered to the filter arrangement in a main direction of flow from below to the top, from which supply lines for the supply of liquid to be filtered branch off to the individual filter elements. A horizontal filter with a higher throughput is provided by the invention, since it is provided that the distributor means comprises distributor lines guided between the wall of the filter housing and the filter arrangement and supply lines in each case distributed across the circumference of the individual filter elements and branching off from the distributor lines, and that the supply lines are in each case provided with a flow reduction chamber, which has at least one communication opening to a distributor line and at least one outlet opening for the discharge of liquid to be filtered above the allocated filter element.

Abstract: A gas laser tube assembly includes a gas laser tube having ends, optical elements each vacuum-tightly closing off a respective end of the gas laser tube, each of the optical elements including a washer-shaped ceramic flange and a terminating plate being transparent to laser radiation and thermally matched to the ceramic flange, the ceramic flange having an outer rim joined to the gas laser tube and a central beam passage opening formed therein, and the terminating plate having two base surfaces, and glass solder connecting the terminating plate to the ceramic flange with the terminating plate covering the beam passage opening and projecting beyond the ceramic flange with at least one of the base surfaces thereof and a method of manufacturing the same.

Abstract: A gas laser tube assembly includes:a gas laser tube having two ends; andtwo optical elements each vacuum-tightly closing off a respective one of the ends of the gas laser tube, at least one of the optical elements at one end of the gas laser tube including a flange and a terminating body formed of a given material;the flange:being rigid, being formed of a metal thermally matched to the given material of the terminating body, being inserted into and connected to the gas laser tube, having the shape of a washer with two sides and a central beam passage opening formed therein, and having a meandering profile with a plurality of right angle turns immediately following each other and pointing alternatingly toward one of the sides of the flange; andthe terminating body:being formed of a material transparent to laser radiation, having the shape of a plate, being inserted into the beam passage opening, being connected to the flange by glass solder, and being extended beyond the tangential plane of both of the sides o

Abstract: A gun mount for light automatic weapons, comprising an upper mount having cradle means for the detachable attachment of the weapon thereto and a lower mount having a circular track and being adapted to be attached to a vehicle in such a manner that the upper mount is rotated about the vertical axis of the circular track. The cradle is pivotable about a horizontal weapon traverse axis. Aiming means comprising a rigid periscope having fixed reflecting mirrors is provided with its eyepiece located below the circular track and whose sight radius is coupled with the traverse motion of the weapon about the weapon traverse axis. The aiming means is about a sight axis which is parallel to the horizontal weapon traverse axis and is attached to a blinder having surface areas which are rotationally symmetrical to the sight axis.
