Title: Controlled release microcapsules
Inventor: MCMAHON WILLIAM A
IPC: A01N25/32
Filed: 1993-03-24
Abstract: Microcapsules are prepared by encapsulating a core material with a capsule shell wall containing glutaraldehyde crosslinked gelatin and at least one water soluble plasticizer that reduces the permeability of the crosslinked gelatin. Optionally, the capsule shell wall also contains a feeding deterrent that dissuades accidental ingestion of the microcapsule. Upon exposing the microcapsules to water, the plasticizer is removed making the shell wall permeable whereby the encapsulated core material is released. Materials such as insecticides, herbicides, plant growth regulating agents, and fungicides may be encapsulated and released at a controlled location, time and rate.

Patent CA-2095494-A1 (CA)
Inventor: LEE RON C
IPC: F25D3/10
Filed: 1993-05-04
Abstract: A method and apparatus for cooling a heat load in which a pressure vessel is provided to contain a cryogen as a saturated liquid   and   saturated   vapor   separated   by   liquid-vapor interface.  The pressure vessel has an inlet adapted to receive a  subcooled  liquid  cryogen  and  thereby  convert  it  to  a saturated liquid through contact with the saturated vapor.  A heated overflow tube projects into the pressure vessel and is level, at one end, with the liquid-vapor interface so that any increase in the saturated liquid overflows into overflow tube and  is  vaporized  to  form  the  saturated  vapor.   The  heat transfer and the reintroduction of the vaporized liquid can be effected  through forced circulation provided by  an  ejector. Preferably the pressure vessel is provided with two outlets for discharging  the  saturated  cryogen  as  saturated  liquid  or vapor.  One or more ejectors having high pressure inlet(s) in communication with the two outlets of the pressure vessel are provided  for  drawing  the  heat  transfer  fluid,  after having cooled the heat load,  into a heat transfer relationship with the overflowed saturated liquid and then into mixture(s) with the  saturated  liquid  or  saturated  vapor,  or  both  and  for discharging  the  same out  of  a  high pressure  outlet  of  the ejector to the heat load.

Title: Method of upgrading residua
Inventor: DE LA FUENTE EMILIANO
IPC: C10G65/12
Filed: 1992-03-13
Abstract: Residua can be upgraded by first partitioning a hydrocracked residua into a vapor fraction and a liquid fraction. The vapor fraction is hydrotreated forming a first hydrotreated product. The liquid fraction is partitioned into a residua fraction and a light liquid fraction. The light liquid fraction can be hydrotreated or hydrocracked to form a hydroprocessed product. The hydrotreated product and the hydroprocessed product are then combined forming a substantially upgraded synthetic crude product refinable as a routine crude in a refinery into products that meet stringent specifications. In particular, residua can be upgraded to make a quality jet fuel fraction and a naphtha fraction containing less than 1 ppmw sulfur and nitrogen.

Patent CA-2107863-A1 (CA)
Inventor: BORGIDA ALEXANDER T
IPC: G06F17/30
Filed: 1993-10-06
Abstract: An information retrieval system implemented as a virtual data base management system which uses a knowledge base management system to provide a problem-oriented conceptual schema for one or more standard data base management systems. In the conceptual schema, a hierarchy of concepts is used to organize individual objects. A classifier determines which concepts an individual object is a representative of and determines the relationship of new concepts to existing concepts. The use of a knowledge base with a classifier permits conversion of queries into concepts and detection of changes in the relationships between individual objects and the concepts. A window-based user interface permits flexible and experimental access to the information. Special features of the user interface permit the user to specify conversion of a query into a concept, to establish monitors to detect such changes, and to define a query by specifying a portion of a graph.
