Patent EP-0266963-A3 (EP)
IPC: A61M16/20
Filed: 1987-10-29
Abstract: A valve (30) in a medical ventilator (10) opens and 
closes as is needed to permit venting of respiratory gasses 
from a patient (14) to the atmosphere. Changes in position 
of the valve (30) are caused by a stepper motor (48), which 
is joined to the valve by a mechanical linkage. The 
stepper motor (48), in turn, is powered by electronic 
signals from a microcomputer controller (26). The 
position of the valve is controlled on a closed loop basis 
by the controller (26), which receives feedback regarding 
the pressure of the proximal gases from a pressure 
transducer (34). The valve (30) is uniquely designed to 
enable the controller (26) to cause the valve to open 
quickly once the patient (14) begins to exhale, and to 
permit accurate control over the proximal pressure as the 
valve (30), is approaching the closed position. In 
particular, the valve (30) comprises a poppet (42) and a 
valve seat (44) which have curved mating surfaces (108, 
110), with the curved surface (110) on the poppet (42) 
being truncated so that pressure gain variance is 
minimized over the range of positions of the poppet (42) 
relative to the valve seat (44). To enhance this improved 
pressure gain characteristic, a cam (52) in the linkage 
between the poppet (42) and stepper motor (48) has a 
variable pitch. All of the components of the valve which 
are exposed to respiratory gases are easily removed for 
sterilization and replacement. Further, the poppet (42) is 
movable to ensure complete closure of the valve despite 
variability in the tolerances of the replacement 
components.

Title: Storage stable components of reactive formulations for bulk polymerization of cycloolefin monomers
IPC: C08G61/08
Filed: 1989-08-02
Abstract: Methods of preparing storage stable components useful for metathesis bulk polymerization of cycloolefin monomers are provided. These components contain cycloolefins with norbornene-functional groups and cocatalysts activated with a halometal compound. In these methods, the cocatalyst is completely formed before the halometal activator is added to prevent the formation of unwanted hydrogen halides, which catalyze undesired crosslinking reactions which destabilize the cocatalyst component. Bulk polymerization systems are provided wherein these storage stable cocatalyst components are paired with catalyst components that together form the complete metathesis catalyst system. For some embodiments, storage stability is aided by the removal of water.

Abstract: An inner product computing unit (12) computes inner 
products of an input pattern whose category is unknown, 
and orthogonalized dictionary sets of a plurality of 
reference patterns whose categories are known. A nonli­
near converting unit (14) nonlinearly converts the inner

or a statistical discriminant function. A determining 
section (18) compares values calculated in units of 
categories using the present coefficients with each other 
to discriminate a category to which the input pattern 
belongs.

Title: Process for obtaining substantially aldehyde-free ketone products
IPC: C07C45/34
Filed: 1989-07-11
Abstract: Tischtschenko condensation of aldehydes is used to 
remove aldehydes from dry ketone-containing streams. 
The Tischtschenko condensation is used to condense the 
aldehydes into esters whose boiling points are 
significantly different than the ketones, greatly 
simplifying the separation of the esters from the 
ketones. An organic extraction step is used to obtain a 
substantially dry ketone containing stream. One 
particularly preferred class of extraction solvents is 
selected from the group consisting of butane, pentane, 
hexane, heptane, octane, nonane, decane and mixtures 
thereof. In particularly preferred embodiments, the 
Tischtschenko reaction is used in the context of 
aqueous-phase catalyzed olefin oxidation to ketones. 
The aldehyde to ester condensation permits easy and 
efficient removal of the aldehyde analogs of the desired 
ketones.
