Abstract: A method of manufacturing an orthotropic deck panel includes cambering a deck plate of the orthotropic deck panel to a first degree of camber in a longitudinal direction, cambering the deck plate to a second degree of camber in a transverse direction, and attaching a rib member of the orthotropic deck panel to the deck plate by welding the rib member to the deck plate. The first degree of camber corresponds to a shape of a surface of which the orthotropic deck panel is a part, and the second degree of camber is configured such that the deck plate is flatter in the transverse direction after the rib member is welded to the deck plate than when the deck plate is being cambered in the transverse direction.

Abstract: A method for producing a mixture of oil and fluid food product includes placing a funnel into a pressure tank such that a stem of the funnel extends at least halfway down into the pressure tank. The pressure tank is flushed with nitrogen. Oil flows into the pressure tank through the funnel. A flow of nitrogen into the pressure tank is maintained through a side inlet of the pressure tank. Oil is dispensed from a pressure tank into the transfer line flowing a flow of fluid food product from a batch tank. The dispensed oil is dispersed into the flow of fluid food product in a inline shear mixer creating oil-in-fluid food product droplets. The oil-in-fluid food product droplets flow to the batch tank with the flow of fluid food product. The oil-in-fluid food product droplets are distributed in a volume of fluid food product in the batch tank.

Abstract: An imaging apparatus having RFID tags associated with wearable components of a system to track the usage and wear levels of the wearable components. The RFID tags can be antennas formed from conductive material impregnated in the wear components such that the RFID tags are worn with the wearing of the wear components. The RFID tags may also be RFID chip tags having memory for storing information, a portion of which is updated in real time. The presence or absence of the impregnated antenna RFID tags or the updated information stored in the chip tags may be used to track usage and wear level of the wear components.

Abstract: Correction of rotary encoder eccentricity in an image forming device having a motor controller using period and position pulse train feedback signals. A motor includes an encoder disc rotating with the motor and at least two encoder sensors disposed at different circumferential positions about the encoder disc. A controller may use a high speed clock to calculate a corrected speed count based on speed counts determined from the number of clock cycles that elapse per cycle of pulse trains from the encoders. The controller may also calculate a corrected position count based at least partly on one or more position counts determined from the number of clock cycles that elapse between periodic sampling points and transitions of encoder pulse trains. The corrected position count may also be calculated based on a position count and one or more speed counts.

Abstract: An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a driven toner distributing member that distributes accumulated toner within the container. The toner distributing member may be driven by a shared speed-controlled motor that further drives an image forming process member. The waste toner system may detect the accumulation of waste toner by monitoring a drive control circuit while the toner distributing member is being driven. For example, a logic circuit may detect the accumulation of waste toner based on monitoring a predetermined frequency of interest of a frequency domain transform of a motor control signal, the frequency of interest associated with the shared motor driving the toner distributing member.

The present invention also relates to purification of low molecular weight monofunctional organic polymer derivatives produced by procedures in which high molecular weight bifunctional poly(ethylene glycol) impurities are removed. The present invention further relates to purification of high molecular weight branched polymer products from low molecular weight starting materials.

Abstract: A method of controlling the speed and position of a motor includes receiving a pulse train indicative of the speed of the motor, and a periodic signal at a frequency greater than the pulse train. The number of cycles of the periodic signal per cycle of the pulse train is counted, and compared to a predetermined number. The speed of the motor is adjusted to match the count to the predetermined number, thus effecting speed control. A command position signal defining a plurality of sampling points is generated. The number of cycles of the periodic signal between a sampling point of the command position signal and an operative edge of the pulse train is counted and compared to a predetermined number. The speed of the motor is further adjusted to match the count to the predetermined number, thus effecting position control.

Abstract: A motor control circuit uses a stored commutation table to effect time-based commutation of a brushless dc motor. Each entry in the commutation table defines a motor winding commutation state, and an exemplary method of open-loop motor control based on the commutation table comprises commutating the motor based on sequentially selecting table entries at a desired selection rate. That is, motor speed is controlled precisely by controlling the sequential selection rate rather than by relying on feedback from the motor. However, motor feedback for closed-loop control may be used in some modes of operation. For example, the method may include closed-loop control or open-loop control depending on the motor speed range, and may transition from closed-loop to open-loop control.
