Abstract: A quick lock device for wristwatch bands comprising: (i) a frame having a pair of overlaps defining a sliding cavity of which cavity is suitable for a sliding movement, one end of the frame being an extension to form an elongated hooking member having a groove along the axis thereof and a latch being formed on the surface of the guiding cavity; and (ii) a sliding member adapted to slide within the cavity being provided with a tongue section at one end of the member and a slide handle to facilitate the sliding movement of the sliding member within the frame, and a latching recess along the axis of the slide, thereby the tongue of the sliding member locks a pin member of a wristwatch being positioned within the groove of the hooking member by sliding the slide handle towards the body of the wristwatch.

Abstract: The invention lies in the field of environmental technology and relates to a compound, in particular for the use, in particular as metabolically inert gas absorber for ruminants on the basis of zeolite, salt and a binding agent. It furthermore relates to a licking element with such a composition, a process for the production of such a licking element as well as its application. The use of zeolite relieves the organism of toxic substances, such as heavy metals and toxins. Clinoptilolite is a dietetically working ballast material, which stabilises the intestinal activities without depriving the body of nutrients such as vitamins and trace elements. Thus it is possible to achieve a reduction of the gas expulsion from the digestive tract. The licking element can be set up in the open, so that even free-ranging animals that belong to a farm can be reached in an easy manner.

Abstract: A vacuum valve is used in vacuum systems having connectors including an internally threaded system component with connector seal, a KF-thread flange with connector seal, and a nut collar with clamping rings and pipe. The valve includes one valve case with an interior and at least two spaced apart openings communicating with the interior. The case defines a valve seat and has a valve member movable in the interior and into positions against the valve seat and away from the valve seat to close and open the valve. A driver is connected to the valve case for moving the valve member. A separate externally threaded nipple is provided around each opening and special sealing surfaces are on each nipple for connection to each of the vacuum system connectors in a vacuum-tight manner.

Abstract: A vacuum valve has a valve stem with a magnetic drive for moving the valve stem in the opening direction of the valve. A piston configuration is connected to the valve stem and is enclosed within a double-cylinder configuration. Overflow or inflow/outflow lines connected between the two chambers of the double-cylinder configuration, contain flow conductance value setting elements such as valves or filters, for setting a damping effect on movement of the piston configuration, thus damping movement of the valve stem.

Abstract: A cathode chamber (1) with a thermionic cathode (3) generates a low-voltage arc discharge in a vacuum treatment chamber (11). Arcing on wall portions of the treatment chamber (11) is prevented by providing a screen (20), operated so as to be electrically floating, in the region of a diaphragm (9), through which diaphragm (9) the discharge is drawn from the cathode chamber (1) into the treatment chamber (11). The discharge is ignited by impressing portions of the cathode chamber wall with the ignition potential, with respect to the potential of the cathode (3).
