Patent CA-2113118-A1 (CA)
Title: Novel growth factor-responsive progenitor cells which can be proliferated in vitro
Inventor: WEISS SAMUEL
IPC: A61K35/30
Filed: 1992-07-07
Abstract: An in vitro culture system for the perpetuation of an unlimited number of neural progenitor cells. Progenitor cells are iso-lated from particular neural regions and proliferated in suspension cultures in the presence of growth factors. The progenitor cells can be induced to differentiate into neurons and glial cells. The ability to perpetuate fetal progenitor cells allows for produc-tion of a large supply of tissue from a minimal number of fetuses for transplantation into an animal with neurodegeneration. The use of juvenile and adult cells for generating progenitors would eliminate the need to obtain fetal tissue and may allow for patient to supply his own progenitors. Such an approach would eliminate the ethical problem of obtaining fetal neuronal tissue as well as the problem of tissue rejection and the required use of immunosuppressive drugs.

Patent CA-2131136-A1 (CA)
Title: Analog radio communicator with fade compensation
Inventor: EMBREE DAVID M
IPC: H04B7/00
Filed: 1994-08-30
Abstract: Abstract An analog radio voice communicator includes a speech encoding system that acts in series with normal analog speech processing. Normal corrupted speech is encoded during operation of the radio voice communicator. The signal strength of the incoming speech signal is monitored. During fades when the signal strength is below a threshold value a fade is recognized and the resultant noise signal remaining is ignored by the speech encoding system. A decoder is included in the communicator and operates in cooperation with the encoder and responds to the fade and for the interval of the fade substitutes reconstructed speech in place of the noise signal. Reconstruction is based on the most likely characteristics of the voice signal wave form to follow the previous actual voice signal. This arrangement uses the filter coefficients generated by linear predictive coding techniques and the excitation vectors developed by excitation analysis to reconstruct the expected speech signal in a synthesis filter.

Title: Continuous centrifugation process for the separation of biologic components from heterogeneous cell populations
Inventor: LAKE WILLIAM C
IPC: C12N5/077
Filed: 1993-06-15
Abstract: A method combining the techniques of immunoaffinity separation and continuous flow centrifugal is provided for selective separation of a nucleated heterogeneous cell population from a heterogeneous cell mixture. The heterogeneous cell mixture is intimately contacted to promote binding thereto by particles having attached a substance that actively binds to a specific desired type of cell out of the cell mixture. The particles are selected so that the sedimentation velocity of the particle/cell conjugate differs sufficiently from those of other cells in the cell mixture to allow its separation by means of a continuous flow cell separator. The method rapidly processes large volumes of cell mixture with the high accuracy expected of immunoaffinity separation and can be used to separate, for example, various types of leukocytes from whole blood, bone marrow concentrate, or a peripheral blood stem cell concentrate; or precursors of lymphokine activated killer cells, tumor infiltrating cells, or activated killer monocytes from lymphocyte or monocyte cell concentrates or from a tissue cell preparation.
