Title: Method and device for the electronic comparison of continuous lines
Inventor: BORNHOLDT WERNER PROF DR
IPC: G06K9/22
Filed: 1988-07-05
Abstract: The method according to the invention serves for the electronic comparison of continuous lines or sets of continuous lines, in particular for the identification of handwriting and signatures. When a continuous line is produced, the writing speed is measured and the division of the continuous line into regions of different speeds is then carried out. Characteristic data of these speed regions can then be their number, their speed value, their sequence and the like, these characteristic data being stored. In the comparison of two signatures, the corresponding characteristic data of the individual continuous lines are then compared with each other. The characteristic data provided are characteristic of a specific person, so that a high reliability of recognition and identification is given. By means of the division into speed regions or segments, a reduction of the quantity of data to be processed results so that more rapid and simpler further processing and, especially, processing in real-time is thus possible.

Title: Hand propulsion system
IPC: B63H1/36
Filed: 1988-12-10
Abstract: The purpose of this appliance, for which a patent is applied here, is to fill a gap which really must be closed. As revealed in Figures A and B, this is a genuine innovation which can produce two different things with the least possible variation. Control and propulsion individually or separately or both together. There are already some possibilities, including some from me, in this sector, but so far nothing like this. The system can be operated very easily by any layman. In moving water, storms, etc., the appliance can be turned from a rudder into a drive with only the smallest change and without any effort. Rudder fracture, for example, is impossible with this construction. That is the aim and object of the propulsion systems.

Patent DE-3910914-A1 (DE)
Title: Apparatus for controlling the cutting depth of coal ploughs
Inventor: REISNER GUENTER DIPL ING
IPC: E21C27/34
Filed: 1989-04-05
Abstract: To control the cutting depth of the coal ploughs used in underground mining, a valve arrangement is allocated to the thrust cylinder. The valve arrangement first of all has a pressure-reducing valve which provides for reduction of the high face pressure so that long service life of the thrust cylinder is guaranteed. A manipulating valve is connected in such a way that it controls the alternate filling and emptying of a metering piston which is connected to the thrust cylinder. An identical quantity of pressure medium in each case is thereby fed via the metering piston into the thrust cylinder, the thrust cylinder in each case performing a stroke corresponding to the displaced quantity. Accurate adherence to the cutting depth is thus guaranteed, especially as the thrust cylinder remains locked until the coal plough has passed the respective thrust cylinder. The pressure drop occurring in the process is utilised in order to actuate the manipulating valve and thus refill the metering piston. <IMAGE>
