Title: Asymmetrically flared notch radiator
Inventor: WHELAN DAVID A
IPC: G01S7/02
Filed: 1992-08-24
Abstract: ASYMMETRICALLY FLARED NOTCH RADIATOR                              ABSTRACT An asymmetrical notch radiating element comprising a metal or metal-clad dielectric substrate into which a tapered slot or notch is disposed. The direction of the axis of the tapered slot lies along any preselected axis and is not constrained to be collinear with the normal to the aperture of the element. An asymmetrical antenna array comprises a plurality of asymmetrical notch radiating elements as described above. Each of the plurality of radiating elements is disposed such that the apertures of each of the elements are substantially coplanar and are at an angle relative to the notch axis. The present antenna uses asymmetric slot lines to control the antenna's electrical per-formance. The precise slot dimensions are chosen to optimize radiation and reduce scattering. The asymmetric flared notch allows optimization of the transmit gain in a direction that is not necessarily normal to the array surface. The asymmetrical notch radiator is designed for use in phased array antennas where reduced radar cross section and wide bandwidth are essential, or in conformal arrays, where the surface normal and array axis are not collinear. The normally high specular radar reflection from the antenna radiators, that lies along the array normal, no longer points in the same direc-tion as the peak antenna gain. This allows the design of a low radar cross section array antenna that does not suffer poor gain due to its reduced cross section.

Patent CA-2089330-A1 (CA)
Inventor: BARNUM THOMAS G
IPC: G05B19/10
Filed: 1993-02-11
Abstract: A programmable fluid or gas control system controls the operation of one or more solenoid valves, each of which in turn controls a gas or fluid dispensing unit.  The control system may be used to control water dispensing fixtures such as sprinklers, sinks, showers, toilets and the like, or it may be used in heating-ventilating-air conditioning (HVAC) applications. The control system may have several configurations.  In one configuration, a master controller controls one or more slave circuits, which in turn control one or more solenoid valves.  Each valve controls at least one gas or liquid dispensing device.  The mode of operation of any particular valve and the timing of its operation may be input either via the master controller or via the associated slave control circuit.  The operation of the valve may be easily changed without changing hardware or software, allowing the system to be used in a wide variety of applications.  In other configurations, the master controller is not used.  Either a single slave control circuit may be used to operate one or more valves, or multiple slave controllers, each controlling at least one valve, may be linked together via a communications data bus to transfer information between them.

Title: Product and method for improving keratinocyte adhesion to the dermis
Inventor: BURGESON ROBERT E
IPC: A61K35/36
Filed: 1992-03-26
Abstract: A purified protein kalinin is disclosed that provides adhesion between epidermal keratinocytes and the underlying dermis. Purified kalinin localizes to the anchoring filaments of basement membranes of human subepithelial skin, trachea, esophagus, cornea and amnion when exposed to monoclonal antibody BM165. The protein has a molecular weight of approximately 400-440kDa and separates on Western blots into fragments of 165kDa, 155kDa, 130kDa and 105kDa when its disulfide bonds are reduced. The epitope of BM 165 is identified on the 165kDa fragment when the blots are probed with BM165. The protein has a rotary shadow image which reveals an asymmetric 170nm long rod having two globules at a first end and a single globule at a second end of the rod. A method is also disclosed for improving adhesion of transplanted keratinocytes to an underlying sub-strate, such as the human dermis, by optimizing the production of kalinin from cultured keratinocytes, or providing an exogenous source of kalinin between the keratinocytes and substrate.
