Title: Masonry block for fair-faced masonrywork
Inventor: SCHENCKING WOLFGANG
IPC: E04B2/04
Filed: 1987-08-19
Abstract: The invention relates to a cuboidal masonry block for erecting fair-faced masonrywork. For the cost-effective production thereof, the proposed masonry block exhibits, on at least one side, a diagonal groove which runs longitudinally in the edge region between at least one side surface and the underside and/or the top side as well as a diagonal groove which runs vertically in the edge region between the at least one side surface and at least one of the end surfaces. Consequently, the masonry blocks can be laid in thin-bed mortar, with the result that vertical joints and horizontal joints with a high degree of dimensional accuracy are obtained, a joint pattern corresponding to the conventional construction type being achieved after the pointing of the diagonal grooves. The invention provides, as a border block or corner block or bonders in a masonry bond, a special form of such a masonry block, which exhibits a diagonal groove running around, in the edge region, between the underside and the side surfaces and the end surfaces or the top side and the side surfaces and the end surfaces. Consequently, all known masonry bonds, for example heading bonds or cross bonds, can be erected as fair-faced masonrywork using the proposed masonry blocks.

Title: Arrangement for the flexible connection of the pans of a face conveyor which are equipped with a side spill plate and a rack bar
Inventor: MUSKULUS ULRICH
IPC: B65G19/28
Filed: 1987-09-10
Abstract: Longitudinal sections of a rack bar on the one hand and of the face conveyor as well as the side spill plate, connected to it, or the machine track on the other hand require different clearance in the longitudinal direction. Connecting members which hold these components with the required longitudinal clearance by different longitudinal dimensions are easily mixed up on assembly. They therefore do not definitely guarantee the clearance between these components which is required for a smooth sequence of operation. In order to prevent mix-ups of the connecting members, it is proposed to equip all longitudinal sections (2a) of the rack bar (2), the machine track (4) and the side spill plate (3) with identical connecting members (5). The latter are to engage in such recesses (7) or on such extensions whose dimensions give the respective longitudinal sections (1a, 2a, 3a, 4a) the required mobility in the longitudinal direction in order to ensure in this way the angular mobility, required for the shifting movement of the face conveyor (1), of the individual pans (1a) relative to one another. <IMAGE>

Filed: 1987-12-10
Abstract: PCT No. PCT/EP88/01095 Sec. 371 Date Jun. 6, 1990 Sec. 102(e) Date Jun. 6, 1990 PCT Filed Dec. 1, 1988 PCT Pub. No. WO89/05432 PCT Pub. Date Jun. 15, 1989.A counterflow plate-type heat exchanger has heat exchange areas which are arranged at an oblique angle relative to the stack direction. This arrangement enables channels to be formed having a smaller width for the passage of fluid than the distance between the plates in the stack direction. As a result, a high rate of heat exchange can be obtained. Corresponding inflow and outflow channels are arranged on opposite lateral sides of the stack. This provides for fluid flow through the stack from one side to the other in a manner such that the entire heat exchange area is contacted by fluid. The channels narrow in the inflow direction and widen in the outflow direction in order to provide optimum flow conditions in the exchanger.

Title: Stress wave gearing
Inventor: MAIER PETER DIPL ING
IPC: F16H49/00
Filed: 1988-05-04
Abstract: The proposal is for a stress wave gearing with a first gearing element (10), which has a circular-cylindrical aperture (11) and on the inner surface of which a deformable tubular second gearing element (12) can be made to roll, the outside diameter of the second gearing element in the undeformed state being slightly less than the diameter of the aperture (11). Rotatably mounted within the second gearing element (12) and concentric with the first gearing element (10) is a third gearing element (16), on which the second gearing element (12) is rotatably arranged and which is deformed essentially elliptically in such a way that it rests at two opposite points on the first gearing element (10). A region (28) of the second gearing element (12) extended beyond the width of the third gearing element (16) is connected in torsionally rigid fashion to a transmission element (25) mounted rotatably and concentrically with the first gearing element (10), the torsionally rigid connection being effected by means of pins (29) which are arranged radially on the extended region (28) of the second gearing element or on the transmission element (25) and engaging in apertures (30) of the other of these two elements. As a result, the transmission element (25) does not influence the deforming second gearing element (12), allowing the latter to be given a very short construction and making it possible to achieve a very compact construction of the stress wave gearing overall. <IMAGE>

Title: Tyre pressure control system for changing the air pressure in vehicle tyres during driving
Inventor: PECHAR FRANZ
IPC: B60C23/00
Filed: 1988-10-05
Abstract: In a known tyre pressure control system, a diaphragm of the venting valve which shuts off the discharge of air is acted on at the top by the control pressure during the control process. The diaphragm opens against the control pressure. The difference in pressure which is available for the discharge of air out of the tyre is reduced by the value of the control pressure. During this process, the driving difference in pressure slowly approaches the zero value in the end phase of the control process, the final value being reached relatively late after an initial rapid reduction in pressure. According to the invention, a tyre pressure control system is proposed in which the venting valve (20) is connected to the tyre (3) via a tyre connection line (8) and is pilot controlled by a shut-off valve (26) which is connected to the control valve (6) and the tyre by two control lines (7, 12). By means of the pilot control, according to the invention, of the venting valve, the air can flow out freely from the tyre at the outside of the wheel without counterpressure due to the control. <IMAGE>
