摘要： A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated. This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station. Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate. The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station. An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible. This saves time in the filling of the bags because time need not be spent waiting for the air to escape out of the powdery material in the bag before the bag can be closed and sealed. A vacuum probe may be inserted into the bag while being filled to help this de-aeration. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

摘要： Ignition control pulses as well as fuel injection control pulses can be obtained from a single signal generator structure by providing two generator units (28, 29) on the structure (1) which includes a rotating shield, vane or gate element (20) to generate by magnetic, for example Hall generator elements, or optical couplers, pulses (U28, U29). The vanes are so positioned, and the rotation thereof, at half engine speed, so arranged that the pulses (U28) generated by the first generator (28) extend over the pulse gaps or intervals of the pulses (U29) from the second pulse generator (29). At least one, and for example two vanes are foreshortened, so that the pulse generated by the first signal generator (28), upon passage of the foreshortened vane (23, 26) commences only when part of the pulse gaps of the second generator (29) has already elapsed. The pulse is applied to an OR-function gate which, then, will provide the fuel injection pulses; the trailing flanks of the pulses from the first signal generator are applied to control the ignition pulses, for example through a frequency divider (43). The number of vanes (22, 23 . . . 27) is twice the number of cylinders (in the example: three).

摘要： Changes in the magnetic field around a Wiegand wire created by a magnetic rotor coupled to a shaft of the engine induce a signal in a sensing coil. The signal is applied to an input switch which forms part of a control circuit. The output of the control circuit is connected to an interrupter switch connected in series with an ignition coil such that a spark is created at the secondary of the ignition coil when the interrupter switch opens. The control circuit maintains the interrupter switch in the nonconductive state for a predetermined percentage of the ignition cycle at low engine speeds and for a lesser percentage at high engine speeds so that enough energy can build in the ignition coil prior to the next interruption at the higher speeds.

摘要： A voltage divider across the interruptor switch contacts provides a measure of the high voltage produced before a spark occurs at the sparkplug. A Zener diode connected to the upper tap of the voltage divider breaks down when this voltage has risen a certain amount as the result of wear of the sparkplug electrodes that widen the gap. The Zener voltage breakdown causes a relay to lock in and to short-circuit a current-limiting resistor in the spark coil primary circuit that allows a higher voltage spark to be produced to assure proper firing of the sparkplugs with the wider gap. Another Zener diode is connected to the lower tap of the voltage divider to sound an alarm and to disable the ignition circuit when the high voltage at which sparks strike in the sparkplug rises to a value for which the insulation of the spark coil and its connection is not designed to withstand.

摘要： To provide for gradual decay of current flow through the primary of an ignition coil, and hence suppression of spurious sparks at spark plugs, a main switching transistor has its conductivity controlled by the conductivity of the emitter-collector path of a control transistor, the base-emitter path of which forms part of a discharge circuit of a control capacitor, which discharge circuit has a sufficiently high resistance to provide for gradual discharge of the capacitor and hence gradual transition of the conductivity of the control transistor.

摘要： To permit use of shaft position transducers which provide needle pulses at predetermined angular positions of the crankshaft of an engine, such as Wiegand-type, and still enable generation of a counted dwell time even under transient conditions, or under low-speed conditions, the output from the Wiegand transducer is connected to a logic circuit which, under normal operating conditions, by use of a counter counts a predetermined time interval after opening of a switch in series with the ignition coil to determine the dwell period or initiation of current flow for a subsequent ignition event by resetting the counter with a reverse polarity subsequent pulse, thereby passing, upon reset, a predetermined count state which, similar to the normal counting of the count state, initiates closing of the switch. Thus, even though the normal counting time has not yet been reached, the reset operation of the counter will trigger closing of the switch and hence sufficient current flow through the ignition coil to store the appropriate electromagnetic energy therein for a reliable spark at the spark plug.
