Patent EP-0394628-A3 (EP)
Title: Computer method for executing transformation rules
IPC: G06F3/16
Filed: 1990-02-13
Abstract: A computer method is disclosed for using rewrite rules 
of the form X(Y)Z=(R) where X is the left context, Y 
is the body of the rule, Z is the right context and R 
is the replacement value for Y if the rule is successful. 
The method places restrictions on how the rules are 
defined to make it possible to organize the rules so 
that they can be indexed efficiently. In particular, 
the body of the rules is not allowed to be defined in 
generic terms, whereas this restriction is not applied 
to the left and right context of the rules. The rules 
are scanned so that the first rule that matches the 
body and its context is the one that applies. 
Ordering the rules into a hierarchy makes it possible 
to have exceptions to any particular rule. The method 
encompasses a model where the rules are applied to any 
input string to create an output string while the body 
of any rule that matches is skipped in the input 
string. When no rules apply to any character of the 
input string, a default rule to copy the string is 
applied. This guarantees that the process will always 
terminate and that it will be loop-free.

Title: Passive acoustics process for monitoring fluidized bed flow
IPC: G01N29/14
Filed: 1990-03-01
Abstract: A method is described for the non-intrusive 
determination of flow anisotropy through the cross-­
section of a two phase fluid bed reactor. The method 
involves measuring wall vibrations of the reactor at 
several positions spaced circumferentially around the 
reactor, and determining the power spectrum as a 
function of frequency. The area of the power spectrum 
under a resonance peak for each position is determined, 
and a change in the area of the power spectrum between 
adjacent positions is correlated with flow anisotropy 
through the cross-sectional plane of the circumference 
of the reactor on which the said positions are located. 
The foregoing may be repeated for another cross-­
sectional plane, and a change in the area of the power 
spectrum between adjacent positions in one plane is 
compared with the corresponding area between adjacent 
positions in the other cross-sectional plane, and the 
difference in changes in the two planes is correlated 
with a change in bed density.
