Title: Isolation of proteins by ultrafiltration
Inventor: WESTFALL PETER H
IPC: A23L11/30
Filed: 1992-02-11
Abstract: 4964.US.01 ISOLATION OF PROTEINS BY       ULTRAFILTRATION                        ABSTRACT OF THE DISCLOSURE A high quality soy protein isolate with a significant reduction in phytate and aluminum is prepared via ultrafiltration.   Defatted soy flour slurry is prepared and adjusted to a pH such that the protein becomes solubilized.  The solubilized  protein  can  pass  through  the  ultrafiltration  membrane.    The ultrafiltration system rejects phytate and aluminum.

Patent CA-2066329-A1 (CA)
Title: Microbial monitoring device
Inventor: STITT DAVID T
IPC: C12M1/34
Filed: 1992-04-16
Abstract: This invention presents methods for detection and evaluation of metabolic activity of microorganisms based upon their ability to consume dissolved oxygen.      The methods utilize a fluorescence detection system which makes use of the sensitivity of the fluorescent emission of certain compounds to the presence of oxygen, which quenches (diminishes) the compound's fluorescent emission in a concentration dependent manner. Respiring microorganisms will affect the oxygen concentration of a liquid medium in which they are immersed. Thus, this invention provides a convenient system to gather information on the presence, identification and metabolic activity of microorganisms by determining their effect on the oxygen concentration of the media in which they are present.

Patent CA-2067217-A1 (CA)
Inventor: EDELMAN GERALD M
IPC: G06V10/764
Filed: 1990-10-10
Abstract: An apparatus capable of sensing the presence of objects in its environment, categorizing these objects without a prior description of the categories to be expected, and controlling robotic effector mechanisms to respond differentially to such objects according to their categories. Such responses include sorting objects, rejecting objects of certain types, and detecting novel or deviant objects. The invention includes a device called a "classification n-tuple" (of which a "classification couple" is a special case) capable of combining signals from two or more sensory modalities to arrive at the classification of the object. The invention operates by simulating certain features of animal nervous system, including neurons with responses determined at each moment of time by inputs received along synaptic connections from sensory means or form other neurons. In this invention, neurons are arranged in "groups", which permits them to act cooperatively while still retaining characteristic individual responses. Groups in turn are arranged in "repertoires", which provide a totality of response specificities sufficient to respond to any of a range of possible input objects. Some of these repertoires are organized as "maps", such that groups responding to inputs that are similar along some dimensional (spatial or abstract) are close together in the repertoire, enabling the repertoire to respond correctly to novel objects that are similar to objects it has encountered previously. Maps in this invention are linked by connections, called "reentrant" connections, that enable the responses of one map to be reentered into the system as inputs to another map. Reentrant connections permit signals from different sensory modalities to be correlated in an ongoing fashion, and they are the basis for the operation of classification n-tuples. The responses of the apparatus of this invention may be improved and optimized for a particular task through the operation of "neuronal group selection", a process which enhances the responses of those neuronal groups in the apparatus which were active in some time interval preceding the production of a useful output action. This process operates by modifying the strength of selected synaptic connections. The value of various output actions is determined, for the purpose of regulating selection, by means which are internal to the apparatus of this invention. Accordingly, the invention is capable of self-organization and learning, and does not require a predetermined specification of correct responses for all possible inputs.
