Title: Multiple electromagnetic tiles for boundary layer control
Inventor: NOSENCHUCK DANIEL M
IPC: B64C21/00
Filed: 1994-06-24
Abstract: The boundary layer of a fluid travelling in a mean-flow direction relative to a surface of a wall of a body is controlled by generating in the fluid a magnetic field B having flux lines along the surface of the wall and an electric current density J traversing the magnetic flux lines in the fluid to form a control region. The magnetic field B and the electric current density J create in the control region a force J X B that can stabilize or destabilize flow in the boundary layer. A plurality of such control regions can be arranged in a two-dimensional array (300) of control tiles that are actuated in a controlled, predetermined pattern at a critical frequency that provides boundary layer control over a given area.

Patent CA-2177941-A1 (CA)
Inventor: ROUTHIER FRANCOIS
IPC: F24F11/00
Filed: 1996-05-31
Abstract: The present invention relates to air-conditioning control, more particularly to a ventilation system well suited for industrial applications, such as for air freshening of intensive livestock farms. The ventilation system comprises a master controller connected by communication links to slave controllers that regulate the operation of individual fan units. The master controller transmits to the slave controllers temperature or rotational speed set points calculated to maintain within the premises desired environmental conditions. The slave controllers enforce the set point (either temperature or rotational speed) by varying the magnitude of the voltage impressed across the excitation winding of the electric motor that drives the fan. At least one slave controller is provided with a temperature sensor allowing the slave controller to modulate the speed of the fan according to the local temperature. This feature is useful in situations when the master controller is no longer capable of sending valid set point data to the slave controller, either due to a malfunction of the master controller or because the communication link is interrupted. The local temperature sensor can also be used as backup to the main temperature sensor of the master controller. Should the main temperature sensor fail, the master controller reads the temperature remotely, over the communication link and this data is used to continue generating set points data that is transmitted to the slave controllers.

Title: Improved Simulated Egg Patty
Inventor: MANDERFELD MICHELLE MROZIK
IPC: A23L15/00
Filed: 1996-01-23
Abstract: Simulated egg patties and simulated egg yolks, and methods of preparing them, are provided. The simulated egg patties and simulated egg yolks have superior mouthfeel and texture characteristics which are similar to a fried egg prepared from a fresh, natural egg. The simulated egg yolks are prepared by freezing a predetermined amount of egg yolk in a predetermined shape whereby the egg yolk structure is modified so that, upon thawing, the egg yolk is gel-like and essentially maintains its shape. The frozen egg yolk can be combined with, or essentially surrounded with, egg white and then cooked to form a simulated egg patty. Preferably the egg yolk is pre-cooled prior to freezing and the frozen egg yolk is tempered prior to cooking.  Upon cooking, the egg yolk portion of the simulated egg patty or the simulated egg yolk has similar mouthfeel and texture to cooked fresh egg yolk.

Patent CA-2197039-A1 (CA)
Title: Fluid control valve
Inventor: GERSTENBERGER GERALD ROSS
IPC: F16K1/36
Filed: 1997-02-07
Abstract: Needle valves which are seated in valve seats defined by circular edges have DELRIN® tips for the purpose of minimizing unseating torque which would otherwise be excessive due to the thermal expansion and contraction characteristics of the valve seats and the needle valves. In salt spreaders with aluminum valve seats and steel needle valves, the needle valves become stuck in the valve seats if the needle valves are seated after operation in frigid weather and the salt spreaders are subsequently garaged to raise the temperature of the valve seat and needle valves. By utilizing the DELRIN® tips, the needle valves do not become stuck.
