the following steps (i), (ii) and optionally (iii) carried 
out in any order: 
   (i) reacting epoxy groups with a compound having 
one active hydrogen in its molecule (c);    (ii) at least partly esterifying secondary or 
tertiary hydroxyl groups; and    (iii) reacting epoxy groups with a primary amine 
(b).
Patent EP-0350278-A3 (EP)
IPC: G09C5/00
Filed: 1989-07-04
Abstract: For more convenient mechanisation, the modulo  m  reduction of a 
binary number P can be carried out by conditionally summing the modulo 
m reductions of a power series of two and then modulo m reducing the 
sum. The modulo m reductions of the series, called the 'residues' of 
the series, can be pre-calculated and stored but this may be 
inconvenient if they are long in terms of numbers of bits. Herein, 
the residues are calculated in sequence by a recursive process, each 
residue being calculated from the next preceeding one, this leading to 
a 'serial' arrangement for generating the residues which can be 
incorporated into a serial modulo m reduction unit. Such a serial 
modulo m reduction unit is convenient for implementation as an 
integrated circuit especially as part of an overall circuit for 
encryption and decryption of digital signals.

Title: Digital demodulator system
IPC: H03H11/04
Filed: 1989-10-12
Abstract: An analog baseband signal (32) modulates a reference frequency carrier signal (38) to provide a double sideband, suppressed-carrier DSB-SC signal. The DSC-SC signal is converted in a voltage-to-frequency converter (54) to a series of pulses, the repetition rate of which is proportional to the level of the DSB-SC signal. The output signal of the voltage-to-frequency converter is demodulated to produce a digitally formatted version (62) of the baseband signal. A notch filter to reflect an undesired signal is provided as a feedback path from the output voltage-to-frequency converter (54) to a negative input of a summer (48) in the input line of the DSB-SC signal. The feedback path converts the frequency signal from converter (54) to a cancellation signal having the format of the undesired signal.

Title: Coding method of image information
IPC: H04N1/417
Filed: 1990-01-26
Abstract: A coding method of a binary Markov information source 
comprises the steps of providing a range on a number line 
from 0 to 1 which corresponds to an output symbol sequence 
from the information source, and performing data compression 
by binary expressing the position information on the number 
line corresponding to the output symbol sequence. The 
present method further includes the steps of providing a 
normalization number line to keep a desired calculation 
accuracy by expanding a range of the number line which 
includes a mapping range, by means of a multiple of a power 
of 2, when the mapping range becomes below 0.5 of the range 
of the number line; allocating a predetermined mapping range 
on the normalization number line for less probable symbols 
LPS proportional to its normal occurrence probability; 
allocating the remaining mapping range on the normalization 
number line for more probable symbols MPS; and reassigning 
the predetermined mapping range to the remaining mapping 
range the half of a portion where the allocated remaining 
range is less than 0.5, when the allocated remaining range 
becomes below 0.5.
