Patent DE-3332389-A1 (DE)
Title: Process and equipment for producing paper or cardboard
IPC: D21B1/02
Filed: 1983-09-08
Abstract: In a process for producing a fibre suspension, in particular from waste paper, a soaking drum is mounted to tilt on a frame, in order to release a variable quantity of fibre suspension from the drum by means of the adjustable angle of inclination of the drum. The support frame in this case is designed so that the drum can be tilted downwards at its end discharging the suspension. The fibre suspension taken off from the drum at a relatively high consistency then passes onto a transport belt whose capacity is designed for the maximum fibre quantity to be taken off. A constant speed of the conveyor belt is sufficient, but it would also be possible to provide a variable speed, in order to adjust it to the fibre quantity to be taken off. The drum is also mounted via support rollers directly on an upper frame, on which the drive means for rotating the drum are provided so that further rotary driving of the drum is possible even during the swivelling and after the swivelling motion of the drum.

Title: Guide apparatus for a running web
Inventor: BRUNNER GERHARD DIPL ING
IPC: B65H23/032
Filed: 1983-09-28
Abstract: The invention relates to a guide apparatus for a running web, especially a textile or plastic web, with devices which have a correcting effect on the web transversely to the web running direction when the web diverts from a desired running direction. Known guide apparatuses of this type operate with clip chains or pairs of nip rollers, which correct the running of the web when required to do so. Driving, controlling and constructing these apparatuses is expensive and demanding. According to the invention, it is proposed to provide at least one roller which is rotatably arranged transversely to the web running direction and parallel to the plane of the web and over which the web runs, to make the roller drivable so as to move in a reciprocating manner transversely to the web running direction and to make the web rest on the circumferential surface of the roller in a form-locking manner exclusively in one direction of movement of the roller respectively. Web-correcting forces are thereby imparted to the web by the roller in a simple and effective manner.

Patent DE-3429110-A1 (DE)
Inventor: KRUMHAUER PETER DIPL ING DR IN
IPC: G09G1/14
Filed: 1984-08-03
Abstract: A process for coding, and a process and device for decoding characters and graphic elements is proposed, in which polynomials are processed. In these, horizontal (y = f(x)) and vertical (x = f(y)) polynomials are used. The polynomials of the contour concerned are calculated with spline functions, in which the running length of the polynomials is optimized. In coding, a characteristic number relating to the type of polynomial, the start and end co-ordinates and the polynomial factors are memorized for each polynomial of the contour. In decoding, the polynomial factors which are, independent of the character size, are converted into and memorized in character-size dependent starting values, for example, four starting values K, L, M, N for a third-order polynomial. Here, K corresponds to the actual function value, M to the second derivative, N to the third derivative and L to the derivative reduced by a/4, and for each contour point a new K-value is determined by adding the previous K-value and L-value, a new L-value is determined by adding the previous L-value and M-value, and a new M-value by adding the previous M-value and N-value. By using the prescribed character width and the relevant K-value determined, and taking into account the type of polynomial, the x, y co-ordinates of the contour points of the character are determined, whereby the xold, yold co-ordinates of the previous contour point are intermediately memorized. The x, y co-ordinates of the previous contour point are compared with the xold, yold co-ordinates of the previous contour point and a positive and/or negative deviation is determined. Depending on the relevant general direction of the contour and the deviations from the contour points the piercing points are selected and memorized.

Title: Process for degritting or regenerating wells, and wells with enlarged capacities
Inventor: MEISTER KARL
IPC: E03B3/15
Filed: 1985-02-05
Abstract: A process for degritting or regenerating wells, which simultaneously involves an enlargement of the capacity of the well, provides that the filter pipe is flushed from inside and the filter gravel wall is flushed from outside. The latter takes place by introducing bores radially outside the filter gravel wall, that is to say in the grown soil, approximately up to the base of the well. The flushing is then, step-by-step, forced out horizontally through perforations in flushing pipes inserted into the bores, while the filter pipe of the well is degritted inside a pipe portion corresponding to the flushing portion concerned.
