Patent CA-2038967-A1 (CA)
Inventor: KOMODA MOTOYOSHI
IPC: H03B5/32
Filed: 1991-03-25
Abstract: Frequency compensation for a crystal oscillator circuit whose oscillation frequency is dependent on source voltage applied thereto.  When a capacitor is added to the frequency compensation terminal of the crystal oscillator circuit, the circuit changes the oscillation frequency thereof on the basis of the capacitance of the capacitor.          A source voltage detector compares the source voltage being applied to the crystal oscillator circuit with a predetermined reference voltage and produces a control signal matching whether the source voltage is higher or lower than the reference voltage.  On receiving the control signal, a control switch turns on or off the contact thereof to add or not to add the capacitor to the frequency compensation terminal.  Assuming that the characteristic of the crystal oscillator circuit is such that the oscillation frequency decreases with the decrease in the source voltage,  when the source voltage is low, the capacitor for frequency compensation is not added so as to increase the oscillation frequency of the crystal oscillator.  Conversely, when the characteristic is such that the oscillation frequency increases with the decrease in the source voltage, the capacitor is added so as to decrease the oscillation frequency.

Title: Method and apparatus to improve fuel economy of internal combustion engines
Inventor: MELENDREZ JULIAN B
IPC: F02B51/04
Filed: 1991-07-23
Abstract: METHOD AND APPARATUS TO IMPROVE FUEL ECONOMY        OF INTERNAL COMBUSTION ENGINES   Abstract of the Disclosure The present invention is a method and apparatus to improve the fuel economy of internal combustion engines by inducing a magnetic field in the fuel as it flows into a carburetor or fuel injector system.  A rubber fuel line, without any metal reinforcements, is used to convey the fuel from an inlet fitting made of steel or aluminum to an outlet fitting, again, made of steel or aluminum.  A magnet is placed so that its south pole is in contact with the rubber fuel line.  A rubber wrap is placed about the magnet and about the portion of the fuel line in contact with the magnet to further focus the magnetic field on the flowing fuel.  The magnetic field induced in the flowing fuel ionizes the hydrocarbon fuel to increase combustion efficiency, thus, increasing fuel economy.

Abstract: THREADING THE WEB INTO A TWIN WIRE DRYER GROUP            ABSTRACT OF THE DISCLOSURE           The dry end of a paper making machine includes a twin wire dryer group following a single wire dryer group.  The paper web is continuously guided by a support belt which moves alternately between dryer cylinders and intermediate deflecting rolls in the single wire dryer group.  In the twin wire dryer group, the web travels over open lengths between dryer cylinders in the two rows of the second group.  A rope guide threads the web into the twin wire dryer group.  The start of the rope guide, called the rope shears, is in the vicinity of the periphery of the last or next to last deflecting roll called the selected deflecting roll in the single wire dryer group.  Between the selected deflecting roll at the start of the rope shears and the preceding selected dryer cylinder, there is a relatively long straight path of travel for the support belt.  Parallel to that path, there is a scraper and a guide plate which deflects the edge strip of the web laterally into the rope shears which is laterally to the side of the web.  The rope guide then threads the web into the second dryer group.
