Patent DE-3830336-A1 (DE)
Title: Screen for magnetic and electromagnetic fields
Inventor: BUEHNE JOACHIM
IPC: H05K9/00
Filed: 1988-09-07
Abstract: In order to screen against magnetic and electromagnetic interference fields, superconducting screening elements are used which cancel the interference field using an opposing field generated in the superconducting layer and so allow complete screening. The screening effect is, in the case of these screening elements, independent of the geometrical design and of the screen thickness as well as of the electrical and magnetic constants of the material. By the method of operation of the screening elements, these elements can be ordered in any desired sequence. The design of the screening elements can be chosen freely.

Title: Method for tuning the sample head of an NMR spectrometer, and an NMR spectrometer designed for carrying out the method
Inventor: KUSTER ANTON
IPC: G01R33/36
Filed: 1988-11-11
Abstract: For tuning the sample head of an NMR spectrometer, the sample head (5) and a standard resistor (6) representing the desired impedance of the sample head are connected into a measuring circuit which responds to the difference between the impedances of the sample head and of the standard resistor. The tuning of the sample head is then carried out in the sense of a minimisation of the difference between the said impedances. For this purpose, special measuring devices were previously used. The connection of a sample head into such a measuring device is very complicated. According to the invention, the receiver circuit (1, 2, 3) of the NMR spectrometer is used directly as the measuring circuit, by firstly substituting the sample head (5) in the NMR spectrometer by the standard resistor (6) and storing the signal delivered by the receiver circuit (1, 2, 3) in the digital computer (4) of the NMR spectrometer as a reference signal, and then comparing, using the computer, the signal delivered from the receiver circuit (1, 2, 3), connected once more to the sample head (5), as a comparison signal with the reference signal stored in the digital computer (4) during the tuning of the sample head. <IMAGE>

IPC: G01C19/04
Filed: 1990-01-10
Abstract: The gyro comprises a drive motor Me, a torque motor Mc, and moving parts such as a flywheel (Vo, Fig 1 a not shown) and a ring of magnets (CA).

A scale factor coefficient KT is established in real time as a function of the estimated temperature using a polynominal relationship of the form:  where KTo is the scale factor of the gyro at a reference temperature To, * small Greek lambda *p represents proportionality coefficients determined by calibration, and n represents the degree of the polynomial. The invention is applicable to thermally compensating gyros used for stabilizing mechanical moving parts or systems used for providing navigational assistance.

Title: Forming half tone raster points - de-arranging regularity of arrangement between density values and partial raster spot forms to achieve desired irregularity
Inventor: GLEIXNER EWALD
IPC: H04N1/405
Filed: 1990-04-06
Abstract: The density values of the scanned original document points falling in lines and columns are assigned to a regular sequence of repeated partial raster spot forms.  The density values determine the concrete partial raster point of corresp. form.  The regularity of the assignment between density values and partial raster point forms (R11,R12,R22) is disassembled to produce a desired irregularity. The ordering between density values and partial raster point forms can be made by a random generator (21) which assigns an arbitrary partial raster point form from all those  available to each density value.  The decision for deranging can also be made dependent about a random generator (22). USE/ADVANTAGE - Producing print forme for colour separations avoiding Moire effect achieving better detail contrast.
