Title: Roofing tile and process for the production thereof
Inventor: SCHMIDT KARL-FRIEDHELM DR
IPC: E04D1/28
Filed: 1982-07-29
Abstract: The invention relates to a roofing tile comprising a ceramic body, having at least two layers (1, 2) of different apparent densities, the structure of the layer (2) corresponding to a conventional body structure layer and the layer (1) being penetrated by macropores. The invention further relates to a process for producing the roofing tile, a pore-forming agent being added to a ceramic composition, said composition being introduced into a mould in layers and being slightly pressed, if appropriate, and the layer comprising the dense-graded ceramic composition then being applied, and this subsequently being fired in the manner which is conventional for ceramics. The layering may also take place conversely. <IMAGE>

Title: Cylinder head for internal combustion engines
Inventor: MELZER HARALD DIPL ING
IPC: F01L3/20
Filed: 1983-01-14
Abstract: A cylinder head (1) for internal combustion engines is composed of a material which has a greater thermal expansion than the material of valve stem (4) and valve disc (3) of an inlet valve (2) arranged in the cylinder head (1).

Title: Load-bearing element for mounting a squared-timber member on a shoulder in a force-transmitting manner
Inventor: BUITKAMP HEINZ G
IPC: E04B1/49
Filed: 1983-06-14
Abstract: The invention discloses a load-bearing element which is preferably used in cargo crates for large and heavy goods, which are exposed to high pressure loadings. The load-bearing element is essentially Z-shaped and serves to connect two mutually opposite side walls of the crate to squared-timber members which extend between said side walls and absorb, on the one hand, the pressure loadings channelled in via the cover and, on the other hand, the lateral transverse forces. Using this load-bearing element makes it possible to dispense with further supporting elements, standing on the bottom of the crate, such as beams or the like for the squared-timber element, as a result of which a considerable amount of space is saved and the material costs for the crate are reduced.

Title: System of exhaust gas heat utilisation of heating boilers fuelled with gas and oil, and reduction of the pollutant effect of environmentally harmful substances
Inventor: ROTHBERG HEINZ
IPC: F24D12/02
Filed: 1983-06-25
Abstract: In this system, the hot exhaust gases are not passed out into the atmosphere via the chimney, but are conducted by a compressor X or a suction fan 15 via heat exchangers 8-11 which deliver the absorbed heat, even below the dew point to the heating system. The resulting acid condensate phase is collected via a condensate pump 12 in the container 13. The remaining exhaust gases with the residual heat can be fed to a heat pump and then cooled in a Freon cooler to minus x DEG C-65 DEG C, to achieve a total condensation. <IMAGE>

Title: Resistor structure on a multi-sensor silicon chip
Inventor: WERTHSCHUETZKY ROLAND DR ING
IPC: G01K7/22
Filed: 1983-07-30
Abstract: In a resistor structure on a multi-sensor silicon chip, the object is to provide a sensor element which can be used to measure pressure, temperature or flow rate. The pressure can be measured with high or reduced precision and the flow rate is measured with reduced precision, and the silicon chip used can have two different crystal orientations. This is achieved by providing four different resistor structures on a silicon chip having a monocrystalline membrane, and by integrating, in the membrane, a first, second and third resistor structure, each formed from four pressure-sensitive semiconductor resistors as a coherently doped region and connecting the four resistors to form a Wheatstone bridge in each case. The edge of the square chip is not reduced in thickness and four temperature-sensitive semiconductor resistors are integrated in the vicinity of the corners; these resistors are connected in series for the purpose of measuring temperature and as a Wheatstone bridge for the purpose of measuring flow. <IMAGE>

Patent DE-3330900-A1 (DE)
Title: Process for producing a fabric, especially a conveyor-belt fabric
IPC: D03D47/46
Filed: 1983-08-24
Abstract: What is described is a process for producing a fabric, especially a conveyor-belt fabric, by means of which an improvement of the edge formation can be achieved on automatic looms. The fabric has, in a known way, longitudinally directed warp yarns having weft loops extending transversely to these. The weft loops are inserted alternately from opposite edge sides and are retained on the side located opposite the insertion side, preferably by sewing by means of a sewing thread inserted by means of a sewing shuttle. A sewn edge and a woven edge are thus obtained on the two longitudinal sides. The woven edge is preferably located respectively outside the sewn edge. The fabric is suitable especially as a conveyor-belt fabric.

Title: Aluminium profile screw-on frame construction for new and old wooden windows and doors
Inventor: BORKHOFF HERBERT
IPC: E06B3/30
Filed: 1983-09-28
Abstract: In these aluminium profile screw-on frames, the outer aluminium profiles (5 + 6) are screwed in a shear-resistant manner to the inner wooden frames (1 + 2) from the tongue and form a common static unit. Using the same aluminium profiles (5 + 6), wooden windows which have already been installed are renovated by screwing the wooden strips (9 + 10 + 11) onto the old window frames (15) according to Figure 2. The single panes (12) are replaced by multipane insulating glass (14). The aluminium profiles (5 + 6) form a prechamber which, with the sealing profiles (4 + 8) cover the screw connnections (13) ouwardly and inwardly. Moreover, any glass rebates in the outer frame and casements can be produced steplessly by displacing the screw-on surfaces. The aluminium profiles (5) screwed on from the casement tongue allow glazing and unglazing without casement glass strips, as a result of which a closed profile unit is achieved on the inside of the wooden casement (1). In each case, an embodiment of this aluminium profile screw-on frame construction for new and old wooden windows is illustrated in the drawing, sheet no. 6. The references in the text and in the drawing correspond. <IMAGE>

Title: Method for recording information or images by means of ink jet printers
Inventor: FLECHTNER VOLKER DIPL ING
IPC: B41J2/21
Filed: 1984-05-04
Abstract: The invention relates to a method for recording information or images by means of ink jet printers having at least two nozzles which are at an angle with respect to one another, the ink droplets being charged electrically and being subsequently deflected between electrodes. The aim and objective is to avoid oblique impacting on the paper, to reduce the "puddle effect" and thus to improve the half tone recording and recording of the colour image. In the method according to the invention, the ink droplets which are ejected from at least two nozzles are provided with one of two predetermined charges so that, after deflection in a homogeneous electrical field, they either fly into collection gates or move on on a flight path which is common to all of them and extends perpendicularly with respect to the recording medium. Thus, some droplets are melted before impacting on the recording medium. <IMAGE>
