Patent DE-2923738-A1 (DE)
Title: System protecting copyright label of program - prevents changes or removals from computer program by checking whether copyright is still stored
Inventor: JOEPGEN HANS-GEORG
IPC: G06F21/12
Filed: 1979-06-12
Abstract: The system, for program in higher languages such as BASIC and FOCAL, automatically checks at random intervals to see whether the characters describing copyright are still present in storage. If these characters are not found in storage then measures are taken to render the program unusable, e.g. by a conditional skip, deletion disabling or falsification. Alternatively, constants needed by the program are derived from the copyright characters in the computer's storage area. Changing the copyright line results in the use of incorrect constants which prevents the program running correctly.
Patent DE-2928998-A1 (DE)
Title: Removing ochre from water well - causing intermittent anodic current flow to produce hydrogen ions
Inventor: RICKERT HANS PROF DR
IPC: E21B41/02
Filed: 1979-07-18
Abstract: The system has one or more anodes set directly in to the porous well pipe at the required points and at least temporarily supplied with an anodic current set such that oxygen is evolved and hydrogen ions produced. The anodic current is supplied at periodic intervals such that the time for which the current flows is small compared to the time for which it does not flow. The current only flows whilst the well is not in use. The cathode is located in the ground. The anodes are made of non-corrosive material such as titanium coated with platinum or with ruthinium oxide, or such as ferrite or carbon etc. The well's pipe may be made of these substances or it may have holes through which wires of this material pass. The system prevents ocherous deposits blocking the filtration holes in the well pipe.

Title: Disc system representing mathematical equations - represents variables by discs mounted on carrier turned through angle to cause variable transposition
Inventor: KUENZEL WALTER
IPC: G06G1/00
Filed: 1979-11-09
Abstract: A simple disc system is used to enable various forms of equations to be represented, based upon four variables. In a positioning system, where the controlled unit is moved by a motor, the revolutions per distance moved is given by:- (r.p.m.X time) divided by 60. Four discs (2,3,4,5) pinned (7,8,9,10) to a carrier disc (1) represent the four variables of the equation. A fifth disc (6) represents the arithmetic operations. The position of the carrier allows the equation to be read directly from the discs. By rotating the carrier through 90 degree increments, the equation may be transposed to obtain one variable in terms of the other three.

Patent DE-3100618-A1 (DE)
Title: Recording device for echo sounders and other short-time measuring instruments
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: G01S7/60
Filed: 1981-01-12
Abstract: Recording devices, particularly for echo sounders, carry the recording element on a circulating belt. If the speed of circulation of the belt is increased in order to improve the resolution of the recording device, the belt begins to flutter as a result of which the recordings of the recording element become unclean. This fluttering of the belt can be eliminated only partly by means of smoothing rails at the rear. These disadvantages do not occur in the invention according to Figure 3. The belt is guided in grooves the sides of which it does not initially contact and therefore runs very easily. If unstable fluttering movements are beginning to build up, this is suppressed even in the initial stage since the escaping parts of the belt immediately touch the guide and are calmed by this. Due to the arrangement according to the invention, high belt speeds and thus high resolution recording instruments are possible without needing strong drive powers for the belt guides.

Title: Plastifying and drying of wood and wood materials for the production of bent parts
Inventor: TROEBS REINHARD ING GRAD
IPC: H05B6/80
Filed: 1981-02-20
Abstract: Microwave plastifying and drying of wood and wood materials for the production of bent parts, in particular for the requirements of the furniture industry. The object of the invention is to utilise the orientation polarisation for heating the wood material to plastify it. The object is achieved with an efficiency at least 40 times greater in comparison with the conventional dampening method and less than a tenth of the time requirement for plastifying by irradiation with a microwave radiation field emitted from an aerial. The most advantageous frequencies lie between 1 and 4 GHz (wavelength between 30 and 7.5 cm). In the case of an aerial power of between 0.5 and 5 kW of the plate-shaped aerials having linear dimensions of between 10 and 50 cm, the wood material in the open or closed microwave chamber is plastified in a matter of minutes at possible temperatures of up to 400 DEG C. The plastified wood material is forced into the desired shape and is dried in the microwave radiation field. The microwave chamber, essentially a metal housing with a dielectric grating and microwave aerial(s) arranged above it, can be provided as a moisture chamber, which can be filled with and emptied of water, for moistening the wood material throughout before plastifying, or as a tunnel chamber for a plastifying and drying operation of the assembly line type.
