Title: Method for the synthesis of sulfonylimidides
Inventor: ARMAND MICHEL
IPC: C07C303/38
Filed: 1989-10-04
Abstract: Method for the synthesis of sulfonylimidides having the formula M((RSO2)2N)y, whrein M is a metal or an ammonium radical quaternary or not, the Rs, which may be identical or similar are organic monovalent radicals, particularly hydrocarbyles and preferably perfluorohydrocarbyles, in C1 to C12, and y is the valence of M. On the one hand, a silazane component selected amongst the silazane compounds M(((R2)3Si)2N)y or the associations of a silazane derivative A((R2)3Si)2N or a fluoride M1Fz of low cross-linking energy is reacted with, on the other hand, at least one sulfonic halogenite component consisting of a sulfonyl fluoride RSO2F or in the association of a sulfonyl chloride RSO2Cl with a fluoride M1Fz, M, R and y having the above-mentionned significations, M1 being selected amongst the Ms and being optionally identical to M, z being the valence of M1 and R2 representing an alkyl in C1 to C4. The imidides obtained for which the R2 are perfluorated radicals and M is an alkaline metal such as Li are usable in association with polyethers for the production of materials of the ionic conduction type for all solid generators in thin films.

Abstract: A catheter equipped with an expansible member according to the present invention comprises  a first lumen whose tip is open, a second lumen whose tip is closed, a foldable expansible member communicating with the second lumen, and a rigidity imparting member consisting of a linear member extending in the axial direction disposed in the second lumen. Therefore, an extreme flection or bend of the catheter is prevented without decrease of the flexibility of the catheter, especially the elastic deformability in the lateral direction with respect to the axial direction of the catheter. Thus, the force applied to the base end portion of the catheter for advancing the tip end portion thereof is surely transmitted to the tip end portion. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the outer diameter of the tip end portion of the catheter including a portion to which the expansible member is attached is smaller than that of the base end portion of the catheter. Therefore, the tip end portion of the catheter can be inserted into a severer stricture portion or in a more peripheral blood vessel. Further, a catheter equipped with an expansible member according to the present invention comprises a first lumen whose tip is open, a second lumen whose tip is closed, and a foldable expansible member communicating with the second lumen, the tip of the expansible member forming the tip of the catheter. Therefore, the expansible member is prevented from peeling off and the tip end of the catheter is prevented from being an injury to the inner wall of a blood vessel when the catheter advances in the blood vessel.

Title: Method and apparatus for controlling single or multiphase a.c. power controllers
Inventor: RUNGGALDIER DIETHARD
IPC: H02P27/02
Filed: 1990-02-05
Abstract: When using phase control of semiconductor valves (4) for controlling AC voltage converters, in order to regulate the power factor it is necessary to determine the phase angle between the current I and the voltage U by measuring the time difference between the points at which the current and voltage pass through zero. However, disturbances superimposed on the mains voltage cause considerable random fluctuations, particularly in the measurement of the times of the voltage zero-passages, which are transferred to the phase angle and can result in an unstable regulation characteristic. It is therefore proposed according to the invention to make use of a reference time for the voltage zero-passage when determining the time difference, which reference time is derived from the measured values for the true times of the preceding voltage zero-passages.

Filed: 1990-08-08
Abstract: ABSTRACT            Thermal Insulation A pipeline 2 has an inner surface 4 which comes into contact with cryogenic fluid at a temperature of 70K.  The outer surface 6 of the pipeline 2 carries a coating of foamed polyurethane having closed cells containing carbon dioxide.  The pipeline 2 is located in an outer sleeve 10.  The annular space 12 defined between the pipe 2 and the sleeve 10 is filled with perlite powder and is able to be purged with dry nitrogen gas.            In operation with the inner surface 4 of the pipelines subjected to a temperature of 70K, the carbon dioxide in the cells of the polyurethane solidifies creating a vacuum therein.  This increases the temperature difference across the polyurethane coating and enables the perlite powder to be maintained at a temperature above 77K so that the nitrogen purgant does not condense.  A relatively simple alternative to conventional vacuum insulation is thereby provided.

Filed: 1990-10-04
Abstract: ABSTRACT OF THE DISCLOSURE      A door latch assembly 10 includes a rack 102 which is moved upon depression of a thumbpiece 12.  Movement of the rack 102 results in rotation of an enmeshed pinion 136 and an assembled spindle 152.  As the spindle 152 rotates, a latch 26 is moved from a latched position to an unlatched position to thereby permit opening of a door 20 on which the door latch assembly is mounted.     When it is desired to lock the door 20, a key-operated lock cylinder 16 is operated to place into motion facilities for moving the rack 102 into a disabled position whereafter depression of the thumbpiece 12 will not result in movement of the rack.    As the rack 102 is moved to the disabled position, teeth 104 of the rack remain enmeshed with teeth 138 of pinion 136.  When the rack 102 is again moved to the enabled position, the teeth 104 and 138 remain enmeshed and thereby avoid any deleterious reactions had they been separated upon disablement of the rack 102 and re-enmeshed upon enablement thereof.
