Abstract: An electric motor driven valve for use in gas meters, has at least one valve unit (V) with a valve body and a valve element, a drive unit (A) and a connection unit (S). The units (V, A, S) can be connected to each other and separated from each other, in a modular manner. The valve element is a spherical or cylindrical valve element that is sealed relative to the valve body by means of only one sealing element, which is preferably a lip seal. The valve body has two recesses in which the valve element is rotatably mounted.

Abstract: The invention proposes a bone plate comprising a bottom side that is to rest against the bone and an upper side opposite to the bone as well as a plurality of holes located along the longitudinal axis of the plate, through which bone screws can be inserted to be anchored to a bone. At least one of these holes is a continuous oblong hole comprising a longitudinal axis running in the direction of the longitudinal axis of the plate. A retaining structure, is provided in a partial area of the lateral side of the oblong hole for engaging the threads of said bone screw to archive an angle-stable fixation of said bone screw in said oblong hole.

Abstract: A gas meter with integrated gas shut-off valve has a housing with a gas inlet and a gas outlet. A device to record the gas flow, a meter mechanism, a gas shut-off valve and optionally a pressure reducer are positioned in a gas flow path between the gas inlet and the gas outlet. The gas shut-off valve is an electrically operated valve with a spherical or cylindrical valve element.

Abstract: In a plug valve with a plug supported around its axis of rotation in a flow passageway of the valve housing, the plug is supported in a floating manner against a spring force pressing the plug against an annular sealing element. The spring force is provided by a spring element bearing against the valve housing and engaging with a trunnion of the plug. The sealing element is supported in a fixed position against a flow passage opening.

Abstract: The aim of the invention is to enlarge the possibilities of use of conventional bone plates and increase their flexibility of manipulation. To this end, the invention proposes a bone plate comprising a bottom side that is to rest against the bone and an upper side opposite to the bone as well as a plurality of holes located preferably along the longitudinal axis of the plate, through which bone screws can be inserted to be anchored to a bone. At least one of these holes is a continuous oblong hole comprising a longitudinal axis running in the direction of the longitudinal axis of the plate. A retaining structure, such as thread flights, is provided in a partial area of the lateral side of the oblong hole, said thread flights, when see in a direction transversal to the plane of the upper side, are arranged only over a part of the depth of the oblong hole.

In the direction transversal to the plane of the upper side, a support structure with smooth walls for the positive fit with a correspondingly configured negative structure at a screw head or screw neck of a bone screw is provided.

Abstract: A fluid-tight cable bushing for a ribbon cable has two profile supports. The ribbon cable extends through an opening in a penetration element, such as a housing for a switch or meter. The bushing has two profile supports each with a first flange having snap-on elements and a second flange. The first flanges extend symmetrical along and enclose the ribbon cable. To form a first fixation point, the snap-on elements are v-shaped and arranged to snap against a first end of the opening. To form a second fixation point, the second flanges extend laterally beyond a second end of the opening. A fluid-tight potting mass covers one of the fixation points. Preferably, the potting mass is disposed in a recess formed in the penetration element about the opening.
