Patent EP-0403031-A3 (EP)
IPC: B01D33/00
Filed: 1983-12-13
Abstract: A suspension of cellular material which is subject to 
trauma is passed from inlet 22 to outlet 34 axially along a shear 
gap between a stationary outer wall 24 and a cylindrical membrane 
62 carried by a rotating spinner 50 and plasma is filtered off 
through the membrane and withdrawn through axial passage 76. 
The membrane has a pore size of not less than 0.4µm. The width 
of the gap and the rate of rotation of the spinner are chosen 
such as to establish a shear rate in excess of 1000 sec⁻¹ across 
the gap. The spinner 50 is driven by magnetic coupling 68, 74 
from outside the housing 40, 12, 44 which thus forms a disposable 
unit.  
     In a construction for separation of anti-freeze solution 
with white cells from frozen concentrated red cells, saline 
solution is introduced through a porous outer wall 12 and passes 
radially through the mixture to carry the anti-freeze and white 
cells through the membrane.
Patent EP-0397299-A3 (EP)
IPC: G06K15/02
Filed: 1990-02-08
Abstract: This invention relates to a method for displaying 
characters on a screen or printer, particularly kanji characters. 
The structure of the character is represented by stems and 
counters, both vertical and horizontal, the counters being the 
spaces between stems. The character is then transferred from 
character to display space. Either the horizontal or vertical 
counters are grouped into a first chain of counters. The non-integral 
counter widths of this chain are adjusted in relation to 
the other counter widths within the chain, selected counter 
widths being made equal to others within the chain in order to 
most faithfully reproduce the desired character. The remaining 
horizontal or vertical counters, if any, are also grouped into 
one or more series of chains which are also adjusted, chain by 
chain. Then the orthogonal set of counters are adjusted in the 
same way. The widths of the stems themselves may also be 
adjusted to more faithfully represent the character in the scale 
at which it will be displayed.

Title: Composition of an active agent for oral administration, especially to ruminants
IPC: A23K40/35
Filed: 1992-01-01
Abstract: 2.1 Active agents such as feed additives and drugs are often to be released in a delayed manner or slowly after their oral administration. In particular in the case of ruminants, little or none should be released in the rumen. Appropriate encapsulations are expensive and, in particular for administration of relatively large amounts of product, are unsuitable and too costly. Known encapsulations of this type also have the disadvantage of a questionable physiological acceptability and/or are not permitted. 
<??>2.2 The novel encapsulation contains relatively thin regions and/or predetermined breaking points, which accelerate the release in comparison to an essentially uniform coating. Angular particulars such as pellets are preferably encapsulated, the encapsulation being formed in such a manner that the encapsulation can break at the edges after the oral administration. Encapsulations are preferably composed of two layers, the inner layer containing a filler plus film-forming agent and the outer layer only containing film-forming agent. 
<??>2.3 The encapsulation is suitable for protected administration of active agents for nutritional purposes, for example methionine, or for medical, in particular veterinary medical, treatment, in particular of ruminants.
