Patent CA-2140980-A1 (CA)
Title: Conveyor oven with improved air flow
Inventor: HEBER ALBERT J
IPC: A21B1/26
Filed: 1995-01-24
Abstract: A  conveyor  oven  is  described  having  increased efficiency from enhanced flow therethrough.   The oven consists of an upper plenum, a lower plenum, and a return plenum.  The upper plenum is disposed above the conveyor and dispenses heated air through nozzles downwardly.  The lower plenum is disposed below the conveyor and dispenses heated air upwardly.   The upper and lower plenums are tapered from a maximum width of 2 1/2 inches to a minimum of no more than 15% thereof across the path of travel of the  conveyor.   A blower  having  a  vertical  axis  of rotation is  located at a midpoint between the upper plenum and the conveyor and a burner is located below the inlet between the inlet thereto and the return plenum. The outlet from the blower directs air through scrolls onto a baffle plate having rounded edges and from there into the upper and lower plenums.   This  scroll-like pattern with rounded edges and, in combination therewith, a similar scroll surrounding the burner tube directing air from the return plenum through the burner tube and into the fan has been found to be responsible for the improved efficiency.

Patent CA-2153970-A1 (CA)
Inventor: DEVANEY DAVID B
IPC: H04W60/04
Filed: 1993-11-17
Abstract: A method and system for identifying the location of mobile units (20) within a cellular telephone system (10). A subset of cells is dynamically assigned to a mobile unit based upon the cell location of the mobile unit at the time of registration. The mobile unit records the subset information, and as long as the mobile unit remains in one of the cells in the subset, it does not re-register its location with the system. The system is able to locate the mobile unit within the assigned subset of cells. When the mobile unit enters a new cell that is not within the subset of cells, it re-registers with the system which then assigns a new subset of cells corresponding to its location within a new cell that did not belong to the previous subset.

Title: Turbo-molecular blower
Inventor: SCHLIE LA VERNE A
IPC: F04D19/04
Filed: 1993-03-22
Abstract: The turbo-molecular pump (14) of the pres-ent invention comprises, basically, a series of ax-ial, rotating high speed rotor disks (20) being in-terleaved with stationary rotor blades (24). The ro-tor shaft (26) is mounted in the blower housing (58) by means of a ferrofluidic rotating seal (28) which prevents contamination and provides vacu-um integrity. Because of the high molecular weight gases and the velocities needed of such, an external multi-horsepower motor drives the blow-er. External cooling is further provided to reduce heat generated by the blower. Due to the high torque available, pressures from 0.1 to 100 torr are possible with high density gases and at high flow velocities.

Abstract: A five valve flanged manifold valve in a straight-flow configuration has a height that is less than 25 percent greater than it width, and in 90° angled flow configuration is less than 50 percent greater than its width. A vent port is advantageously positioned on the front face of the valve in both configurations.  A vent port control valve is located a rear surface of the straight flow configuration manifold valve, and on a bottom surface of the 90° flow configuration manifold valve.  Neither configuration of the manifold valve requires a separate access hole for use during manufacture to form and shape the internal crossflow passageways.  Both configurations have significantly less mass than the counterpart prior valves of their respective types.
