Abstract: The grinding wheel (2), which is intended in particular for plunge-cut grinding, has a first abrasive-layer part (5) which contains fine-grained diamonds as well as a further abrasive-layer part (9) which contains larger diamond grains. This grinding wheel can be a straight wheel as well as a cup wheel. Known embodiments of such grinding wheels either cannot obtain the required surface roughness or exhibit high wear, since they do not have a continuous high proportion of diamonds in the outer marginal area of the end face as protection against rounding-off of the outer edge. In order to remedy this, provision is made for the abrasive-layer part (9) to be provided with diamond grains of larger grading which are arranged in a single layer parallel to the axis of rotation of the straight wheel, the diamonds being arranged at right angles to the axis of rotation in several layers and being held in mutual contact in an electro-deposited bond (10).

Abstract: A wood/metal window with a fixed glass has a window frame (1) made of wood, on which are fastened, as the outer shell, metal profile sections (2) which form a first abutment, provided with a seal (5), for a glass pane (6). Glass-holding strips (7) made of wood are provided, which are releasably fastened to the window frame (1) and have a second abutment, likewise provided with a seal (33), for the glass pane (6), so that the glass pane (6) is held with a pressing force between the two abutments. The glass-holding strips (7) are fastened to the window frame (1) by means of local clip connections (8) which are arranged in a concealed manner. Each clip connection (8) consists of a receiving part (9) placed on the window frame (1) and of an insert (10) arranged on the glass-holding strip (7). For taking up the moment acting on the glass-holding strip (7) due to the pressing force, there are provided between the receiving part (9) and insert part (10) two supporting points (18, 21) arranged at a distance, of which the supporting point (21) facing the inner room (15) is designed in such a way that it can be lifted out. <IMAGE>

Abstract: A rolling-lobe air spring has a rolling lobe which is formed from elastomeric material and is provided with embedded strength supporting layers. Both ends of the rolling lobe are in each case fastened to a fitting. Under normal operating conditions, the rolling lobe forms a rolling fold which changes during contraction and expansion. In order to reduce the technical cost during production and assembly of the air spring, and to reduce its weight, one end region of the rolling lobe is constructed as a more greatly reinforced lobe wall section (15) which has stable dimensions with respect to the air spring internal pressure and the external loading by the rolling fold (17). The rolling lobe created in this way rolls off with its rolling fold over the reinforced lobe wall section, that is to say over itself. <IMAGE>

Abstract: A burner (1), with a conical shape opening in the direction of flow, is composed of two part cone members (2, 3) which are positioned on top of one another and the central axes (2a, 3a) of which run in a displaced manner in relation to one another in the longitudinal direction. From this displacement, a tangential inlet slot to the interior (17) of the burner (1) is in each case formed over the length of the burner (1). The fuel supply takes place centrally via a nozzle (9) and tangentially in the region of the inlet slots via a fuel pipe (10, 11) in each case, which is provided with fuel openings (21) which there take on the injection of the fuel (6). Above each inlet slot, a duct is formed, which is equipped with an injector (12, 13). Additional fuel (4) is introduced by this injector. The air/fuel mixture with fuel from the injector (12, 13) and/or fuel from the fuel pipe (10, 11) flows generally in the form of an air/fuel mixture (8) through the tangential inlet slots into the interior (17) of the burner (1). There, if necessary, further mixing with the fuel (5) from the nozzle (9) takes place.

Abstract: Cooling-air cooling units for gas turbines usually have tube plates (4, 7) in which the heat-exchange tubes (5) are mounted so that the air to be cooled is separated from the fluid which takes up the heat. Rapid changes in temperature frequently occur, in particular in the tube plate (4) at the air-input end. In order to reduce the mechanical stresses produced by these changes in temperature, the invention calls for this tube plate (4) to be held in place on one side only while, at the same time, a secure connection is provided between the air-inlet chamber (1) on the tube side and the walls (3) of the container surrounding the tubes.

Abstract: In order to limit damage when pressure exceeds or falls below a certain permissible level, ducts carrying gas or liquid are provided with automatically closing shut-off fittings. These fittings are kept in the open position by elements which counteract the closing force. The purpose of the invention is to create an automatic closure device of simple design which will reliably and automatically cause the shut-off fitting to close if the pressure exceeds or falls below the permissible range. The proposed closure device is provided with at least one variable-volume hollow body which can be pressurized; this acts as the closing force counteracting element. The hollow body has at least one relief device (9) to which the operating pressure is applied. If the pressure exceeds or falls below the permissible value, the closure sequence is triggered: the relief device (9) opens, the pressure at that location falls and the closing force becomes effective and closes the shut-off fitting (1). A closure device of this type can be combined with various types of usual commercial shut-off fittings (1).
