Title: Method for external calibration of ion cyclotron resonance mass spectrometers
IPC: H01J49/26
Filed: 1990-04-06
Abstract: An ion cyclotron resonance mass spectrometer is 
externally calibrated, i.e. a calibrant compound is not 
present at the same time as the sample to be analyzed, by 
determining changes in the relative number of ions in the 
cell. This may be done by obtaining a spectrum of the 
sample to be analyzed, measuring the trapping sidebands, 
and then determining the trapping frequency from those 
sidebands as the difference between the trapping sideband 
frequencies and divided by four. The cyclotron frequency 
can then be found from the effective measured frequency 
and the trapping frequency, and the mass is then obtained 
as a function of the cyclotron frequency. Another 
approach is to measure the magnetron frequency directly, 
and then to calculate the cyclotron frequency from the 
measured effective frequency and the magnetron frequency. 
A third approach is to introduce a calibrant compound into 
the cell and produce several output signals with various 
relative numbers of ions. Calibration is accomplished by 
using the known relation  
m = k₁B/f + k₂E/f²,  
or variations thereof, where m is the mass of the ion to 
be measured, k₁ and k₂ are constants, B is the 
magnetic field strength, f is the measured frequency for 
that ion, and E is an electric field term which is 
dependent on the cell geometry, magnetic field strength, 
and total number of ions present in the cell. An output 
signal is obtained for the sample under analysis and, by 
knowing the relative number of ions that is to be 
 
 
incorporated into the E term, the values for the various 
factors can be inserted into the calibration relation to 
arrive at mass measurement values.

Title: Spark erosion electrode and method for manufacturing such an electrode
IPC: B23H1/04
Filed: 1991-02-01
Abstract: The invention relates to a spark-erosion electrode which consists of a conductive ceramic material, and to a method for manufacturing said electrode. In particular, said electrode is manufactured by introducing the slip-type ceramic material into a porous female tool, a body forming the electrode being produced by removing liquid. Said body is then fired in a firing furnace. Electrodes manufactured in this way are extremely temperature-resistant, with the result that a high spark-erosion voltage can be applied. Compared with the manufacture of known metal electrodes, the manufacturing method is very simple and cheap because no cutting operations are necessary. <IMAGE>

Title: Method and apparatus for non destructive testing of superficial layers, especially of big construction pieces having a complex form
IPC: G01N29/07
Filed: 1991-07-31
Abstract: The invention relates to a method and an apparatus for nondestructive testing of superficial layers, in particular of large construction pieces having complicated shape. Objects to which the invention relates are mechanical engineering, and plant and equipment construction pieces. In the method, the laser pulse is split, according to the invention, into two spatially separated subpulses of approximately equal intensity and the focal lines of both subpulses are located on the surface of the construction piece. The spacing between the two focal lines is adjusted by moving the beam splitter or individual components of the beam splitter or the like along the optical axis to an extent which depends on the geometry of the construction piece, the frequency of the ultrasonic waves and the attenuation and is kept constant for subsequent measurements. The method is carried out in an apparatus in which, according to the invention, a beam splitter is situated between the cylindrical lens and the surface of the test piece, an adjustable spacer is situated at the position of the two focal lines to fix the spacings between the beam splitter and the surface of the test piece and the ultrasonic test head is arranged on the continuation of the connecting line between the centres of the two focal lines.

Abstract: A cryptosystem utilizes the properties of
discrete logs in finite groups, either in a public key
message exchange or in a key exchange and generation
protocol. If the group selected has subgroups of
relatively small order, the message may be exponentiated
by a factor of the order of the group to place the
message in a subgroup of relatively small order. To
inhibit such substitution, the base or generator of the
cryptosystem is chosen to be a generator of a subgroup of
prime order or a subgroup of an order having a number of
relatively small divisors. The message may be
exponentiated to each of the relatively small divisors
and the result checked for the group identity. If the
group identity is found, it indicates a vulnerability to
substitution and is rejected.
