Title: Method for adjusting a contact spring set
Inventor: BERKEL EGON
IPC: H01H49/00
Filed: 1985-10-10
Abstract: A contact spring set of a relay has a displacement/force characteristic (1) which has a number of bends (inflection points). A first straight regression line (2) is determined from the measured pairs of values from which that corner point of the characteristic (1) is obtained which is furthest from the straight regression line (2). The characteristic (1) is split into two subregions at this point, for which second straight regression lines (3) are determined. The precise values of the corner points of the characteristic (1) result from the distances between the characteristic (1) and the second straight regression lines (3). In consequence, the position of the corner points can be determined purely by computation. The function of the contact spring set is governed in accordance with the values of the corner points. The contact spring set is thus adjusted as a function of these values. <IMAGE>

Title: Measuring device for measuring the position and orientation of a body
Inventor: SCHIELE GUENTER DIPL ING
IPC: G01B5/00
Filed: 1986-01-30
Abstract: A description is given of a measuring device for measuring the position and orientation of a body relative to a fixed reference element, which is particularly suitable for checking a programme-controlled equipment arm. The measuring device according to the invention is distinguished in that it is mounted by means of two flanges on the reference element or on the body. Attached to the flanges (1, 2) are intermediate elements (3, 26) which can rotate about an axis (A-A or F-F) perpendicular to the respective flange, and to which, in turn, there are joined connecting elements (9, 16) which can pivot about an axis (B-B or E-E) perpendicular to the axis of rotation and of which one can additionally be rotated about its longitudinal axis (D-D) and which can be pivoted relative to one another about an axis (C-C). In order to measure each pivoting or rotating movement, provision is made in each case of an angle sensor from whose signals a signal-processing device determines the position and orientation of the plane of the movable flange (1) and thus of the body. The measuring device according to the invention thus has the advantage that it is exclusively angular measurements which are required to determine the position and orientation.

Title: Determining the age of writing
IPC: G01N33/32
Filed: 1986-02-06
Abstract: To determine the age of writings, small samples are taken and brought into solution a number of times. Both the amount of solvent and the dissolution time are prescribed exactly. Dissolution can be accelerated with the aid of ultrasound. The 5 to 7 solutions are applied one after the other onto an HPTLC plate according to known rules. This is followed by the quantitative evaluation of the subsequent high-performance thin layer chromatography with the aid of a TLC scanner and the evaluation with the aid of a laboratory calculator by mathematically calculating a numerical value for the gradient of the resulting curve, an exponential function, which is to be viewed as an indicator for the age of the writing.

Title: Hydraulic oscillating valve
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F01L25/04
Filed: 1986-03-21
Abstract: Hydraulic oscillating valves are special valves for the control of pressure medium in hydraulic systems. They permit the automatic control of working cylinders in constant stroke sequence as long as pressure medium flows to the pressure-medium feed. By means of the invention constant stroke sequences of a working cylinder (25) in its end positions or overload stroke blocking by identical forces, arising in the process, on the end faces of the control spool (2) by the pressures of the pressure medium in the end chambers (15 and 21) to the end chambers (16 and 22) are initiated by virtue of the fact that the force of the respective restoring spring (17 or 18) pushes the control spool (2) into a middle stroke position in which a previously closed control bore (5 or 4) is opened and the uniformity of forces on the end faces of the control spool (2) is terminated. In the process, the end chamber (21) is always connected in a throttled manner to the working connection (B), and the end chamber (22) is always connected in a throttled manner to the working connection (A). Upon re-starting by connecting pressure medium to the pressure-medium feed (P), the piston rod of the working cylinder (25) controlled as described always travels at first in the direction of the arrow. <IMAGE>

Title: Method and device for improving the resolution in the digitisation of an analog signal
Inventor: HENNING MANFRED DIPL ING
IPC: G01F15/06
Filed: 1986-04-09
Abstract: To improve the quantisation-related resolution accuracy in the digitisation of analog signals with a wide dynamic range, it is proposed to digitise the unamplified analog signal and the amplified analog signal separately. The resultant amplified digital signal is then amplified or correspondingly divided by the reciprocal gain factor. The digital signals thus produced are finally combined area by area by a weighting-type of adding up. In the area of large values of the analog signal, only the unamplified digital signal is used. In the area of small values of the analog signal, only the digital signal amplified back to normal level is used. In a transition area of medium-sized values of the analog signal, a sliding, preferably linear signal transition occurs between the two digital signals. For this purpose, a weighting factor, which is variable in the transition area, is derived from the amplified digital signal and is correspondingly taken into consideration in an addition circuit for forming the final digital signal.

Title: Drive for lateral stops in sheet deliverers
Inventor: BORMANN GUNAR DIPL ING
IPC: B65H31/38
Filed: 1986-10-15
Abstract: The invention relates to a drive for lateral stops of sheet-processing machines, in particular printing machines. The aim of the invention is to provide a mechanical drive for lateral stops, which allows precise stack formation, even in the case of stiff printing carriers with large trimming differences and, with little technical expenditure, ensures maintenance-free and interference-free functioning even at a high operating speed and with a large amount of soiling in the sheet delivery. The object of the invention is to provide a drive for lateral stops, in which, starting from a uniform movement via a forced gearing, a rest phase is achieved on the output drive member to fix the sheets in the hovering phase and high aligning forces are achieved in this phase with a low drive moment, in which case a defined maximum force shall not be exceeded. The object is achieved in that two four-bar linkages arranged one after the other and connected to one another constitute the drive, in that, in an operating position, a connecting rod is assigned to a crank and a connecting rod is assigned to an arm of an angle lever in or approximately in an extended position (Figure 2). <IMAGE>

Title: Clock (timepiece)
Inventor: HALFEN NORBERT
IPC: G04B19/30
Filed: 1987-04-23
Abstract: A clock having a dial 2, mechanism 3, hour hand 7, minute hand 8, and second hand 9 is modified, for better and more comfortable reading of the second intervals, to the effect that the second hand 9 is rotatably arranged behind the dial 2 and can only be seen throught the cutouts 4 in the dial 2. The cutouts 4 are arranged at uniform angular distances around the point of rotation (fulcrum) of the hand; they follow a closed contour line 5, 5' or freely selectable shape. The second hand 9 appears in each case behind a cutout 4 as indicating background; in order to enhance the display effect, the visible area of the second hand 9 can be designed to be reflecting or phosphorescent or else to be illuminated. The idea of the invention can be applied to conventional timepieces with a mechanical time display of any shape, that is to say for example wall-mounted clocks, grandfather clocks, table clocks, or wristwatches. <IMAGE>

Title: Arrangement for temperature compensation of scintillation dosimeters
Inventor: SEYFRIED PETER
IPC: G01T1/208
Filed: 1987-07-04
Abstract: The display of scintillation dosimeters is greatly dependent on the ambient temperature especially because of the variation of the gain and of the dark current of the secondary electron multiplier SEV with temperature. It is known to connect a temperature-dependent resistor (for example NTC) in series with the voltage divider for supplying the dynodes in order to reduce this influence. Corresponding compensation circuits have only an incomplete effect because of the nonlinear characteristic of the NTC resistors; in particular, they cannot compensate for the influence of the dark current. To be able to achieve a desired nominal sensitivity of the dosimeter independently of the respective ambient temperature, a temperature sensor (6) is attached to the SEV, as shown in the basic diagram, the output quantity of which sensor (for example voltage) is converted into a digital value in an analogue/digital converter (7). This digital measurement value of the temperature is used as address for a memory (8) into which values of the supply voltage of the SEV had been written which, in accordance with calculation with known temperature coefficients of the gain and known voltage dependence of the sensitivity for each temperature within the selected temperature range just result in the desired nominal sensitivity and the values of the dark current at the same temperatures and sensitivities. The voltage value read out for the prevailing temperature controls, via the DAC1 (9), via ... Original abstract incomplete. <IMAGE>

Title: Method and device for setting the addresses of subscribers connected to a bus
Inventor: POLLY EDGAR DIPL ING
IPC: H04L12/403
Filed: 1987-10-24
Abstract: The subject of the invention is a method and device for setting the addresses of subscribers which are connected to a bus, and via the bus to a central processing unit. The subscribers (3, 4, 5) are connected in series in daisy-chain fashion, via a separate control line (9) from the central processing unit (2). By a signal with a defined binary value on the control line (9) at the input to a subscriber (3, 4, 5), the subscriber accepts an address which is assigned to it from a transmission telegram, which is generated in the central processing unit, on the bus, and outputs the defined binary value to the control line. If the signal with the defined binary value at the input of a subscriber (3, 4, 5) fails, the daisy-chain connection is broken. If the daisy-chain connection exists, each subscriber outputs the received address to the bus (1), as the response to the poll of the central processing unit. <IMAGE>
