Title: Process and apparatus for recording and reproducing signals on and from magnetic tapes
Inventor: KUSSEROW BERND ING GRAD
IPC: G11B20/06
Filed: 1981-07-14
Abstract: In the case of such a process, the signals occurring as analogue voltages pass via a modulator for frequency modulation to the recording head and the information stored on the magnetic tape is output by the reproducing head via a demodulator for frequency demodulation as an analogue voltage. Usually a linear characteristic is used. According to the invention, a characteristic of such a type that a constant change in input voltage ( DELTA UE) brings about a constant change in relative frequency <IMAGE> over the entire range of deviation is used for modulation/demodulation. In the case of the apparatus for carrying out this process, the modulator (2) is preceded by an exponentiator (1) and the demodulator (7) is followed by at least one logarithmator (8, 18). <IMAGE>
Patent DE-3128435-A1 (DE)
Title: Mechanism for automatic stroke adjustment
Inventor: KOBAYASHI TETUO
IPC: F16C1/22
Filed: 1981-07-18
Abstract: A mechanism for automatic stroke adjustment, intended for a control cable, has an adjusting member, such as an adjusting lever or disc cam, with first and second locking or engagement pins and is pivotably connected to the inner cable via a movable pin. The mechanism furthermore has a lever which is provided with first and second surfaces. While, in the rest condition of the lever, the adjusting member can be moved freely relative to the said lever in order to compensate for expansion or contraction of the inner cable, the rotation or pivoting of the lever brings the first and second locking or engagement pins respectively into contact with each of the above locking surfaces, against which they are pressed, thereby locking the adjusting member on the lever and hence allowing the inner cable to be operated to a sufficient extent.

Patent DE-3142939-A1 (DE)
Title: Photographic camera equipped with a computer flash unit
Inventor: ETTISCHER HELMUT
IPC: G03B15/05
Filed: 1981-10-29
Abstract: A pivotable diaphragm member (4) having a small aperture opening (4c) and a filter lever (6) articulated thereon and having filter areas (6a and 6c) are influenced by an exposure control device in such a manner that under low ambient light an electromagnet (2) retains the diaphragm member (4) via a holding spring (1, 1a). By this means, a large aperture (5) comes into effect and the filter regions (6a, 6c) release light-sensitive elements (7a) (exposure control) and (7b) (flash control) arranged in the path of movement of the filter regions, so that below a defined ambient light, full-power flash illumination is carried out. Above a defined ambient light, with the position of the diaphragm member (4) staying the same, an automatic changeover of the computer flash unit to partial power flash (fill-in flash) occurs. At a higher level of ambient light, the electromagnet (2) releases the sprung diaphragm member (4) so that the smaller aperture (4c) comes into effect. The filter range (6a) arrives in the course of this in front of the light-sensitive element (7a) and the filter range (6c) in front of the light-sensitive element (7b). By this means, an exposure time appropriate to the smaller aperture (4c) is achieved and the reflected light from the flash, because of the effect of the filter (6c) must act longer on the light-sensitive element (7b) according to the reduction in aperture, in order to achieve the preset amount of light from the flash for fill-in. <IMAGE>

Patent DE-3226295-A1 (DE)
Title: Actuator
Inventor: HAAS FRANZ
IPC: F15B15/10
Filed: 1982-07-14
Abstract: An actuator for actuating a locking device has on its actuating rod (2) two spring arms (6, 7) which are guided out of it at an acute angle and are located opposite one another and which carry a roller body (8, 9) at each of their free ends. Each of the roller bodies (8, 9) is assigned a fixed guide track (12, 13). The two guide tracks (12, 13) are made sinusoidal, so that they first come nearer to the actuating rod (2) and then go further away from it again. Since the spring arms (6, 7) are prestressed resiliently outwards, there occurs a snap effect, by means of which the actuating rod (2), after overcoming a dead centre, assumes one end position or the other. <IMAGE>

Patent DE-3234608-A1 (DE)
Title: Method and circuit arrangement for generating a position-independent object signature
Inventor: KRAFT HANS RAINER DR ING
IPC: G06K9/46
Filed: 1982-09-16
Abstract: The method of functioning and its circuit implementation enables a position-independent object signature to be formed. The formation of such a signature significantly simplifies and accelerates the position-invariant classification of two-dimensional objects (industrial pattern recognition). The invention is based on the formation of a structure-specific data string (object signature) which is independent of position and orientation. The hardware implementation is effected with the aid of an image processing processor which contains the logic operations (dyadic operators) suitable for the digital computation. The separated object is split into an object-characteristic data string (object signature) independently of its instantaneous position via dyadic operations by a set of translation- and rotation-invariant decomposition functions. Part 2 of the system, the segment area correlator, is a specific correlation circuit which correlates the generated object signature by hardware means, that is to say at high speed by direct comparison of the "unknown" pattern in all possible positions with each reference element. The advantage of the structure according to the invention lies in the simplicity of the methods used, that is to say in simple operations suitable for digital computation.
