  • Publication number: 20200210968
    Abstract: Systems and methods for generating a sensor driven optimized maintenance program are provided. A first maintenance plan for an apparatus type is received; the first maintenance plan defining maintenance tasks for the apparatus type and defining intervals at which the maintenance tasks are to be performed. Historical sensor data, historical scheduled maintenance data, and historical unscheduled maintenance data are received and correlated to determine a predictive value of the sensor data. One or more maintenance optimization objectives of an operator of an apparatus of the apparatus type are received, and the sensor driven optimized maintenance program is generated, based at least on the predictive value of the sensor data and the maintenance optimization objectives. The sensor driven optimized maintenance program includes an adjusted one of the defined intervals.

  • Publication number: 20200023382
    Abstract: A separator unit includes a tank defining an internal volume and having an inlet and an outlet. An insert is provided within the tank, the insert including a down cylinder substantially centrally disposed within the tank and a baffle assembly at an external side of the down cylinder. The baffle assembly defines first and second inlet flumes for flowing incoming water from an external side of the down cylinder to an internal volume within the down cylinder. Inward ends of the first and second inlet flumes are positioned and oriented to create first and second vortex flows that progress downward within the internal volume, wherein a rotational direction of the first vortex flow is opposite a rotational direction of the second vortex flow in top plan view.

  • Patent number: 5910890
    Abstract: A control circuit drives the coil of a contactor in response to a control voltage being applied. The control circuit includes a power supply that produces a regulated output voltage from the control voltage. The onset of the regulated output voltage starts a timer which controls the width of pulses produced by a PWM controller. The pulses control a transistor that applies the control voltage to the coil. Initially the pulses cause a high current to flow through the coil to close the contactor and after an interval of time the timer signals the PWM controller to shorten the pulses which applies lesser current to the coil to keep the contacts closed. A flyback circuit provides a relatively low reverse voltage drop path in parallel with the coil to maintain the electromagnetic field during the periods between the pulses. When the control voltage is removed to open the contactor, the flyback circuit provides a high reverse voltage drop path to promptly dampen the coil current.

  • Patent number: 5814955
    Abstract: A control circuit for an overhead crane motor includes a low supply voltage monitor to disconnect the motor from the control circuit and ensure brakes engage in the event of interruption of power supplied to the crane. A sensor circuit detects whether voltage supplied to the control circuit drops below a predefined threshold level which is greater than a voltage magnitude produced by the motorN operating in a regenerative mode during a power interruption. A switching circuit responds to sensing supply voltage below the threshold level by disconnecting electrical current to a relay coil which causes contacts to open which result in the motor being electrically disconnected from the control circuit. As a result of that disconnection, voltage produced by the motor operating in a regenerative mode does not inhibit electrically controlled mechanical brakes from engaging.

  • Patent number: 5742015
    Abstract: A sealed contactor for switching electric current has a switching assembly that includes a movable contact which selectively bridges a pair of stationary contacts to provide an electrical path therebetween. The moveable and stationary contacts are mounted to a body of electrically insulating material to form a unitized structure. A separate actuator assembly has an enclosure which contains an electrically operated driver with a linkage that extends into the switching assembly to alternately operate the moveable contact into engagement with and disengagement from the stationary contacts. The switching assembly is sealingly attached to the actuator assembly in an interlocking manner that prevents arcs produced between the contacts from escaping outside the electric current switching apparatus. Nevertheless, the switching assembly is capable of being easily removed and replaced as a single unit from the actuator assembly when repairing the contactor.

  • Patent number: 5561734
    Abstract: An electric tool including a variable speed switch assembly including a potentiometer having a central rotatable member defining a bore with a noncircular cross section and a molded plastic speed control wheel housing the potentiometer. The speed control wheel includes a central post with a cross section corresponding to the cross section of the central potentiometer bore such that the central post can be housed in the central bore in only one relative position with respect to the central rotatable member. The variable speed switch assembly also includes a switch cover having projections which snap into designated holes provided in a circuit board such that the switch cover and the circuit cannot be incorrectly assembled. The switch cover includes a stop member that extends into a semi-circular recess in the speed control wheel to provide mechanical stops so that rotational movement of the speed control wheel corresponds with the range of the potentiometer.

  • Patent number: 4453120
    Abstract: A control system for a generator for regulating the field current received from an exciter includes a phase control regulator circuit which produces an output voltage having a duty cycle which is proportional to the generator output signal. An oscillator circuit is responsive to the output signal of the phase controlled regulator circuit and produces a pair of controlled circuit pulses whose duty cycle varies accordingly. Control circuit pulses from the oscillator circuit are coupled via a coupling transformer to a rotating current control circuit which controls the generator field current supplied from the exciter in accordance with the oscillator control pulses.

  • Patent number: 4325350
    Abstract: An alternator-powered breakerless capacitor discharge ignition system for an alternate firing two-cylinder outboard motor provides improved timing characteristics at low, as well as high, engine speeds and prevents reverse engine rotation. The alternator rotor and stator assemblies define a first magnetic circuit which provides constant polarity, constant power pulses for charging a single capacitor in the system. The alternator rotor and trigger assemblies define a second magnetic circuit which provides synchronized narrow trigger pulses, successive one's being of opposite polarity, to operate an electronic control circuit to effect timed capacitor discharge to a pair of spark plug ignition coils in the system. The first magnetic circuit includes a pair of relatively narrow ceramic permanent magnets spaced apart on the alternator rotor flywheel for energizing series-connected, oppositely wound, spaced apart low-speed and high speed stationary windings in the stator assembly.
