Title: Automatic material cutter -  has CNC system with edge monitor and synchronised cutting head with fabric movement on two axes
Inventor: HERZOG ARNOLD
IPC: B23K26/08
Filed: 1990-08-20
Abstract: Computer numerically controlled cutting system, giving shaped cutting to fabrics or paper or film has a drive system (26,27) moving the cutting head (25) along one cutting plane along a co-ordinate line (Y). Actual cutting points (S) along the line are set as co-ordinates by the position of the cutting head (25) on one side, and by the lateral positioning of the fabric (4), through a drive which moves it along the other co-ordinate line (X). Pattern edges are identified by a photo-electric unit (24) or a mechanical monitor, to give the co-ordinates of the monitored points (A) along the pattern edge during cutting, and while the fabric is moved along one or both directions. Monitored co-ordinates are converted into electrical signals, at the monitoring time point, or the image (24) is passed to a computer which gives the various monitored points through a program working on the run of contrast or brightness signals along the pattern edge. Control (28) generates cutting signals and setting data for the first drive (27), the cutting head (25), the drive (21,22) to move the fabric (4) and/or for the tracking of the photoelectric unit (24) according to the monitor's co-ordinate signals. Photoelectrical unit (24) tracks the fabric (4) along the determined cutting line, synchronised with the cutting head (25), or the cutting head (25) movement is by a separate drive from the drive to the monitor (24). During a cutting action of the fabric (4) along a line at right angles to the fabric movement line, the material (4) is steadily moved and, on a reverse of the cutting line against the current direction of fabric movement, the direction of fabric (4) travel is changed over.

Patent DE-4041590-A1 (DE)
Title: Determining depth of vehicle which emits sonar signal
Inventor: ARENS EGIDIUS DIPL ING
IPC: B63G8/39
Filed: 1990-12-22
Abstract: The method involves using a transducer arrangement (12) installed on a submarine (10) for measuring the angle of incidence of the sonar signals. The transducer arrangement consists of hydrophones arranged along a side wall of the craft. The submarine is set into two different alignments of its longitudinal axis and the angle of sonar signal incidence measured for each alignment setting. A horizontal angle and a vertical angle, representing the depth (T), are derived from the angles of incidence, whereby the relationship between the angles is sin (angle of incidence) = sin (horizontal angle)*sin (vertical angle).
Patent DE-4042227-A1 (DE)
Inventor: MENGES WILHELM DIPL ING
IPC: D21B1/32
Filed: 1990-12-29
Abstract: A device for reprocessing, that is to say for disintegrating, used packaging materials, for example unsorted household paper, is described. The device essentially consists of a first comminution unit (14), a downstream trough-like housing (2) with an agitator (4, 6) rotating therein and a further comminution unit (18) located in the material outlet shaft (16). The device is also provided at its lower end with a heavy dirt collection chamber (26). The comminution units (14 and 18) are exchangeable and, depending on the processing requirements, it is possible to choose between purely cutting tools, more chopping or even disintegrating tools. The first comminution unit (14) serves for comminuting raw material with in part large surface area to give a conveyable size of pieces, while the second comminution unit (18) essentially serves for fine comminution and disintegration of the material. In the interposed trough, purification of the material can take place, it being possible to operate with washing fluid circulation via the connections (38, 34, 36 and 28). In this case, low-density stock operation is envisaged. The device can, however, also be operated in the high-density stock range, where disintegration can already start in the trough (2). The stock leaving the device has been pretreated in such a way that it can be separated by means of screen-sorting devices into its components which are to be treated further.
