Title: Controlled release drug formulation
Inventor: CALANCHI MASSIMO MARIA
IPC: A61K36/53
Filed: 1991-04-15
Abstract: The invention provides pharmaceutical compositions with the property of targeted controlled release of active principles which act pharmacologically within the intestine and in particular within the colon and the terminal portion of the ileum. To attain this object the active principle is prepared in multiparticle multidose form and is covered with at least two membranes, one of pH-dependent solubility and the other insoluble but permeable to the intestinal fluids. While the covered active principle remains in the stomach and in the initial intestinal portion, ie while the pH is less than 5.5, it is not released. Only when it reaches an environment of higher pH (small intestine or colon) does the pH-dependent membrane dissolve to commence release of the active principle. From this moment the second membrane, which is pH-independent but permeable to the intestinal fluids, acts to slow down and control the dissolution of the medicament within the small intestine-colon tract.

Title: Cationic resin containing blocked isocyanate groups suitable for use in electrodeposition
Inventor: VALKO JOSEPH THEODORE
IPC: C09D175/04
Filed: 1991-06-05
Abstract: A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed. The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups. The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups. The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates. The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.

Abstract: A portable storage device, for example a secure smart card, contains network identification information for a processing unit that is connectable to a data communications network, which processing unit includes a device reader for reading the portable storage device. The portable storage device includes storage and an access controller. The storage holds a network identity for the processing unit and at least one encryption key. The access controller is operable to control access to the storage by implementing key-key encryption. An embodiment of the invention thus provides a medium not only for storing a network identity for processing unit, but also for other secure information such as an encryption key associated therewith. The processing unit is operable to access a secure portion of the storage of the portable storage device by supplying a request key to the access controller of the portable storage device, and, in response to receipt of an access key from the access controller, to send an encrypted command to access the content of the storage of the portable storage device. In response to the return of an access key, the processing unit can be operable to use the access key to encrypt a command for access to a secure storage in the portable storage device.
