Patent CA-2112761-A1 (CA)
Title: Control knob assembly for a cooking appliance
Inventor: RAY KEITH
IPC: F24C3/12
Filed: 1994-01-04
Abstract: ABSTRACT      A control knob assembly includes a control knob and a track body disposed in the control knob.  A cam arm mounted at one end thereof to the control knob contains on the other end a cam follower which rides in a track disposed within a top surface of the track body.  The control knob is slidable over the track body, and is alternatively locatable in extended and retracted positions.  When the control knob is located in a retracted position, the cam follower is releasably secured in a notch contained in the track.  A pushbutton stop located in the control knob is spring-loaded to move to a radially extended position when the control knob is extended, thereby aligning the pushbutton stop with an extended portion of the track body, permitting actuation by the user of a two-step gas valve by sequentially depressing and rotating the control knob.   19.

Patent CA-2137464-A1 (CA)
Inventor: DE BRUIJN RONNY B
IPC: G05B19/418
Filed: 1993-06-01
Abstract: A secure front-end communication system which couples a plu-rality of actively redundant process control computers to a computer network. The system includes a front end computer which is capable of establishing time limited communication contracts with one or more computer entity on the computer network. Each time limited communication contract is based upon an acceptable response to the transmission of an unpredicable signal from the front end computer, such as an encrypted transformation of a pseudo-random number gen-erated by the front end computer. A security table is used to identify the network entities that are permitted to send write command mes-sages to the process control computers to which the front end compu-ter is connected. The front end computer also includes at least one per-missive table which is used to determine whether a write command message from the network entity should be transmitted to the process control computer for which the message was intended.

Patent CA-2139877-A1 (CA)
Title: Hematopoietic facilitatory cells and their uses
Inventor: ILDSTAD SUZANNE T
IPC: A61K35/28
Filed: 1993-07-09
Abstract: The present invention relates to mammalian hematopoietic facilitatory cells (FC). In particular, it relates to the isolation, characterization and uses of the FC. The FC of the present invention can be distinguished from all other known bone marrow cells by their morphology, cell surface phenotype and in vivo function. It has now been established that purified hematopoietic stem cells alone or bone marrow cells depleted of FC do not readily engraft in a recipient. When co-administered with other bone marrow cells, especially the hematopoietic stem cells into a recipient, the FC  enhance their engraftment, without apparent adverse biologic activities. In fact, the ability of the FC to enhance the engraftment of bone marrow cells in establishing lymphohematopoietic chimerism without producing graft versus host disease also induces donor-specific tolerance to permit the permanent acceptance of donor's cells, tissues and organs. Therefore, FC may have a wide range of applications, including, but not limited to, hematopoietic reconstitution by bone marrow transplantation for the treatment of cancers, anemias, autoimmunity, immunodeficiency, viral infections and metabolic disorders as well as facilitation of solid organ, tissue and cellular transplantation.
