Patent CA-2145138-C (CA)
Inventor: BIRD WARREN M
IPC: B23D61/12
Filed: 1995-03-21
Granted: 1999-10-05
Abstract: A variable thickness linear saw design is proposed for enabling maximum reduction of the thickness of the kerf associated with such saws. Typically, such saws have cutting teeth mounted on the leading edge of a supporting plate. In the improvement of this saw, this supporting plate is given two discrete thicknesses relative to the kerf. A first and narrow thickness (relative to the kerf) longitudinal segment is used parallel to and adjacent the supported teeth. This first and narrow thickness longitudinally extending segment only occupies a fraction of less than half and preferably about 20% of the full width of the saw behind the supported teeth. A second and expanded thickness (relative to the kerf) longitudinal segment is used for the remaining width of the saw. The reduced thickness of the narrow tooth supporting section of the saw forms in the case of the linear saws a preferred exit path for sawdust, this preferred exit path being immediately adjacent and behind the supported teeth of the saw. A variable thickness linear saw of the proposed design exhibits greater lateral stiffness than does a conventional linear saw of uniform thickness. Further, the saw can be subject to greater tension to resist deflection.      Finally, the narrow linear segment supporting the teeth can be shown to have superior resistance to gullet cracking when incorporated to band saw construction. Tension increases in such band saws up to approximately 40% for a given width of kerf can result with consequent improved resistance to transverse forces and improved linearity of the kerf.

Granted: 2000-09-19
Abstract: An improvement on locomotive bubble-type fuel level measuring systems test or monitors the integrity of the bubble-type pneumatic system by observing the rate of bubble formation, in addition to gauging fuel level. A bubble-type fuel level detection system bubbles a volume of air through a bubble tube.     As air exits from the bottom of the tube, bubbles form in the fuel. These bubbles cause small variations in back-pressure in the tube as each bubble grows in size and eventually breaks free from the opening in the tube. The frequency these variations is proportional to the airflow or bubble rate at the bottom of the bubble tube such that pneumatic leaks or other problems can be detected by declaring a problem condition if the bubble rate falls below a predetermined threshold.

Abstract: A bidirectional voltage translator (102) includes a first port (200/400), a second port (202/402) and a bidirectional translator circuit (208-215/404-408, 410, 412-415) coupled between the first and second ports (200/ 400, 202/402). The first and second ports (200/400, 202/402) communicate signals at a first voltage level and a second voltage level, respectively. The second voltage level is different from the first voltage level. When a first port signal input at the first voltage level at the first port (200/400) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the first port signal into the second voltage level at the second port (202/402) and disables translation of a signal at the second port (202/402) to the first port (200/400). When a second port signal input at the second voltage level at the second port (202/402) is detected, the bidirectional translator circuit (208-215/404-408, 410, 412-415) translates the second port signal into the first voltage level at the first port (200/400) and disables translation of a signal at the first port (200/400) to the second port (202/402).
