Title: Method for determining the instantaneous state and the future state of a technical process with the aid of nonlinear process models
Inventor: KALLINA GUENTER DR ING
IPC: G05B13/04
Filed: 1981-08-21
Abstract: In this method, a greater number of process data which, in particular, cannot be directly measured, is calculated from a number of input process data and reference variables and stored in a first process simulator which is operated in real time in parallel with the process. Using a correction computer, process data in which differences between the real and the simulated values are to be expected are continuously monitored and the input variables of the process algorithms are appropriately corrected in the first process simulator. A second process simulator which is operated with at least ten times the computing speed referred to real time calculates the process data describing the state of the technical process at a future time from the corrected and stored data in the first process simulator and from further operating criteria such as limit values and optimization parameters at predetermined time intervals, which process data are indicated and/or used for influencing the reference variables of the process. The method is used in the automation of complex technical processes (energy conversion, chemical reaction sequences).

Title: Apparatus for securing pressure plates in laminate presses
Inventor: MUELLER WALDEMAR
IPC: B30B15/02
Filed: 1981-08-22
Abstract: The invention relates to the fixing of pressure plates or die-plates made of ferritic stainless steels or other magnetic materials on steam plates of presses, as are used in particular for the surface formation and refinement of plates in wood, paper and plastics processing industries and the rubber industry. The aim of the invention is to increase the life and maintain the quality of the products produced therewith over a longer period of time by substantially reducing the material stresses in the surface formation or refinement elements. The object of the invention is to achieve this aim by dispensing with the clamping devices known hitherto and by completely eliminating the sagging of the said elements still present even when using clamping devices of the customary type. According to the invention the aim is achieved by embedding adhesion elements of the permanent-magnet or\and electromagnetic type in the underside of the upper steam plate or of the extrusion die of suitable presses. The adhesion elements are preferably concentrated in the area of maximum bowing of the pressure plate. Their magnetic flux is directed predominantly towards the pressure plate. The apparatus is also suitable for securing deformed pressure plates where use thereof is advantageous.

Title: Triangular indexable insert for turning tools
Inventor: ECKLE OTTO
IPC: B23B27/14
Filed: 1981-08-27
Abstract: In a triangular indexable insert, in particular for fine machining, a main cutting edge (3, 3a, 3b) encloses an acute angle with the adjoining secondary cutting edge (4a, 4b, 4). A radius (R) is provided at the transition of both cutting edges (3, 3a, 3b and 4a, 4b, 4 resp.), and the side length (L) of all three sides is the same size. The radius (R) is about 0.15 to 0.3 times as large as the side length (L) of the indexable insert (1), and the centre (M) of this radius (R) is offset from the centre of the indexable insert (1) at a distance (a, a1) from the main cutting edge (3, 3a, 3b) which corresponds to about 0 to 0.3 times the radius (R). <IMAGE>
Patent DE-3136443-A1 (DE)
Title: Process and apparatus for zero-balancing a measuring head in cylindrical grinding machines
Inventor: BELTHLE HEINZ ING GRAD
IPC: B24B49/04
Filed: 1981-09-14
Abstract: The invention relates to a process for zero-balancing a measuring head (2) in cylindrical grinding machines, the measuring jaws (7, 8) which can be displaced with respect to one another and belong to the measuring head (2) resting, in the operating position, diametrically opposite one another on a workpiece (10) and the measurement values of the measuring head (2) being fed to a machine control means in order to guide a grinding tool (9). In known processes, the measuring jaws, when the workpiece was removed, were displaced towards one another until they were in abutment in order thus to define the actual zero point. Since the tracing heads (11), however, were subject to wear, owing to their abutment on the workpiece (10), during the machining of the workpiece, the finished dimensions of the workpieces removed were checked by hand in order to repeat the zero balancing in the event of excessive erroneous dimensions occurring. As a result, however, the production time of a workpiece was increased untenably. The invention proposes to raise the measuring jaws (7, 8), at any pre-selectable point in time, from the workpiece (15), to pivot the measuring head (2) to a reference measuring pin (12) and to rest the measuring jaws (7, 8) diametrically opposite one another on the reference measuring pin (12) in order then to set the measurement value, given by the measuring head, as zero point of the measuring head (2). Owing to this process, not only is an erroneous dimension due to the wear of the tracing heads (11) of the measuring jaws (7, 8) to be avoided, but possible heat expansions may also be taken into account. An advantageous apparatus for carrying out the process is represented in Figure 4. <IMAGE>

Patent DE-3207621-A1 (DE)
Title: Frame body
Inventor: RUMP HANS-JOACHIM
IPC: A47B47/03
Filed: 1982-03-03
Abstract: According to the invention, frame bodies made of bars can be extended by further frame bodies made of bars to the side, upwards and in various depths in order thus to compose furniture such as cabinets and shelving systems. The object is achieved by four holes in each case in the ends of the bars running horizontally towards the rear, into which holes attachment means can be inserted for connection to bars running perpendicular thereto. A different depth is achieved by a further four holes in the centre of the bar. Due to this solution, there is only one intermediate side between two frame bodies. The bars (2) running perpendicular to the bar (1) have a counter-profile (7) to the profile of the bar (1) which prevents displacement by surrounding the bar (1). <IMAGE>

Title: Process for producing a road surfacing
Inventor: BILDSTEIN JOACHIM
IPC: E01C7/18
Filed: 1982-06-30
Abstract: The invention relates to a process for producing a road surfacing having a substructure of unbonded grainy material and a superstructure comprising an upper base course of bituminously bonded grainy material and a wearing course. By choice of suitable materials and corresponding placing methods, an intimate bond of the materials used is to be achieved and stratification is to be avoided. This is achieved by using for the substructure coarse-grained refuse incineration slag with a small fine grain fraction, which slag is compacted after dumping in place, by using for the upper base course a mixture of broken grains having a high voids content, with exclusive use of washed crushed sand and an amount of bitumen just adequate for adhesively bonding neighbouring grains, the mixture being compacted by shaking in the hot state immediately after placing, and by the wearing course of bituminously bonded chippings with washed crushed sand being applied directly to the upper base course.

Title: Method and devices for firmly joining building or construction elements
Inventor: SPAHN DIETER
IPC: B23K1/20
Filed: 1982-09-25
Abstract: With the invention, surface areas allocated to one another of building or construction elements made of the same or different materials are firmly joined to one another according to a novel method. To this end, the surface areas to be joined are placed against one another, are then subjected to friction cleaning by a friction tool by reciprocating displacement relative to one another, and, during the friction cleaning or after it is complete, are firmly joined to one another by fusion welding, brazing or cold-setting or hot-setting adhesive bonding or the like, whereupon the surface areas firmly joined to one another are removed from the working station. In order to achieve this, a static friction-cleaning frame, a movable friction tool and an associated vibration generator are connected to a welding electrode of an opposite electrode and a welding generator. To carry out the further joining phases, a brazing or adhesive-bonding device, instead of the welding appliance, can also be in operative connection with the friction-cleaning device.

Title: Mosaic printing head with piezoceramic drive
Inventor: SAILER ERHARD DIPL PHYS DR
IPC: B41J2/295
Filed: 1982-11-24
Abstract: Maximum energy conversion is achieved in the bending elements of mosaic printers, serving for the piezostrictive drive, if the bending elements have a triangular shape. As a result, all the bending elements can be arranged in one plane and all the ceramic plates on a common spring disc. The reduction in the number of individual parts, which is made possible thereby, simplifies the production and assembly. Another advantage is that, if the bending element is designed in the form of a triangle, there are no losses of material during the division of the strip-shaped ceramic raw material. <IMAGE>
