Patent EP-0325147-A3 (EP)
Title: Circuit arrangement for a voltage-controlled constant voltage source with an input side rc network
IPC: G05F1/46
Filed: 1989-01-10
Abstract: The input of a voltage-controlled constant-current source is connected, apart from via the RC network with a resistor in the series branch and a capacitor in the shunt branch, to a first terminal, also via a further resistor and a diode to a second terminal. A reference voltage supplied to the input via the first terminal and the RC network resistor can be suppressed by a control voltage supplied via the second terminal, the diode and the further resistor. The control voltage suppresses the reference voltage due to the resistance ratios. The junction between the further resistor and the diode is connected via a third resistor to the output of the constant-voltage source via which, when the diode is loaded in the reverse direction, a reverse current flowing through it is bypassed which eliminates the possibility of the reverse current influencing the constant-voltage source. <IMAGE>

Patent EP-0352447-A3 (EP)
Title: Virtual lookaside means and method
IPC: G06F12/08
Filed: 1989-06-06
Abstract: A virtual lookaside facility is provided for 
maintaining named data objects in class-related data 
spaces in virtual storage, readily retrievable by user 
programs. A search order is associated with each user, 
specifying an ordered list of "major named" which are, 
in effect, sequentially searched for a specified "minor 
name", or data object, to obtain a virtual storage copy 
of that data object. As data objects are placed into a 
virtual cache, existence information, implicit in the 
naming structure, is captured and saved. This 
information is relied on later in retrieving objects 
from the cache. The data isolation provided by 
maintaining class data and control blocks in individual 
data spaces is exploited to prevent failures relating 
to one class of objects from affecting the others, and 
to handle latent program users, following failures, 
effectively.  
     An LRU-like trimming technique is used to remove 
less useful objects from the cache when cache space is 
fully utilized.

Title: Products rich in vegetable origin and water-soluble function, obtaining them, their use and compositions containing them
IPC: C08B37/06
Filed: 1989-09-01
Abstract: Products rich in plant cell wall, originating, for example, from higher plants which are naturally rich in pectins, from algae or from by-products, such as wheat bran, potato pulp, oil mill shells or residues, and the like, are modified so as to contain a fraction of water-soluble polysaccharides which is higher than, in particular which is equal to at least twice, that existing naturally, without modification of their overall chemical composition. To obtain them, water is added if need be to the natural product in the divided state, to form a mixture suitable for being subjected to a shearing treatment, and the resulting product is subjected to a shearing force before extrusion, resulting in modified products as aggregates which can be converted into powder. After aqueous extraction, conducted directly on the extruded product, a water-soluble fraction is obtained, from which, for example, pectins are isolated, with a degree of methylation >75%, and the extraction residue which, after drying and grinding, can be employed as alimentary fibres, like the extruded product which, having a low water content, can be employed directly.
Patent EP-0387855-A3 (EP)
IPC: C08F291/00
Filed: 1990-03-14
Abstract: A process for preparing polymer particles is disclosed. 
The process comprises polymerizing polymerizable monomers by 
the seed polymerization in the presence of a polymer 
emulsion comprising water-insoluble low molecular weight 
polymer particles, in an amount of 0.5-30 parts by weight 
(on solid basis) per 100 parts by weight of polymerizable 
monomers, having a weight average molecular weight of 500-­
10,000 which are prepared by emulsion polymerization or 
soap-free polymerization of radically polymerizable monomers 
in the presence of a molecular weight modifier. Said seed 
polymerization of polymerizable monomers is carried out (i) 
by initially not charging or charging less than 30% by 
weight of said polymerizable monomers to the polymerization 
mixture and (ii) after the polymerization conditions is 
established, by continuously or intermittently adding the 
remaining portion of said polymerizable monomers to the 
reaction system. The process provides far more excellent 
polymerization stability than conventional seed 
polymerization processes. It can produce high quality 
polymer emulsions containing less amounts of agglomerated 
components, and ensures improved process operation, e.g. 
decreased dirt in the polymerization reaction vessels, and 
higher productivity, e.g. better filtration performance.
