  • Patent number: 11503945
    Abstract: A beverage making machine having a cartridge holder with an upper portion movable in pivotal and/or linear ways relative to a lower portion. An actuator for the cartridge portion may include a handle-actuated spur gear and link to move the upper portion, which may be guided in movement via a cam and cam follower engagement. Information from a cartridge detector may be used based on movement of cartridge holder portions, e.g., as an upper portion moves from an open position to a closed position. A mixing chamber may be held by a drawer so as to be removable, and movement of the drawer may engage/disengage the mixing chamber from a fluid supply.

  • Publication number: 20220251587
    Abstract: Methods and compositions are provided for the improvement of double-strand-break-inducing agent activity in eukaryotic cells, through the usage of one or more morphogenic factors or developmental genes. The morphogenic factor may be provided to the same cell or to a different cell than that comprising or receiving the double-strand-break-inducing agent. The morphogenic factor may be provided to a cell as a polynucleotide composition on a recombinant vector, and may be placed on the vector outside of a T-DNA border. The morphogenic factor may be provided via an upregulation of an endogenous gene. The morphogenic factor, or the double-strand-break-inducing agent, may further comprise a cell penetrating peptide. The morphogenic factor may be co-introduced with a vector comprising RepA.

  • Patent number: 8004222
    Abstract: A negative sequence feedback circuit is connected to monitor and minimize unbalances in a high-frequency ac carrier signal provided to a motor/load for the purpose of detecting rotor position. The negative sequence feedback circuit detects unbalances in the high-frequency ac carrier signal and generates negative sequence feedback. The feedback is combined with command signals used to generate the high-frequency ac carrier signal, and the combination of the command signals with the negative sequence feedback is provided to an inverter for generation of the high-frequency ac carrier signal, wherein the negative sequence feedback reduces unbalances in the resulting high-frequency ac carrier signal such that a balanced high-frequency carrier signal is provided to the motor/load.

  • Patent number: 7091702
    Abstract: The present invention is a generator control system where each generator in the system has an associated controller. Each controller communicates generator data or information with the other controllers in the generator control system. Each of the controllers includes a digital signal processor for analyzing the generator signal from the associated generator and information from the other controllers in the generator control system. The controllers each compare their generator signal with a system average and adjust the associated generator until the generators all supply equal amounts of power to the system.

  • Patent number: 4546293
    Abstract: This invention relates to a motor control system for a brushless DC motor having an inverter responsively coupled to the motor control system and in power transmitting relationship to the motor. The motor control system includes a motor rotor speed detecting unit that provides a pulsed waveform signal proportional to rotor speed. This pulsed waveform signal is delivered to the inverter to thereby cause an inverter fundamental current waveform output to the motor to be switched at a rate proportional to said rotor speed. In addition, the fundamental current waveform is also pulse width modulated at a rate proportional to the rotor speed.A fundamental current waveform phase advance circuit is controllingly coupled to the inverter.

  • Patent number: 4526272
    Abstract: An endless, laterally flexible and bendable belt conveyor particularly adapted for coal mining applications in facilitating the transport of the extracted coal up- or downslope and around corners in a continuous manner is disclosed. The conveying means includes a flat rubber belt reinforced along the middle portion thereof along which the major portion of the belt tension is directed so as to cause rotation of the tubular shaped belt when trammed around lateral turns thus preventing excessive belt bulging distortion between adjacent belt supports which would inhibit belt transport. Pretension induced into the fabric reinforced flat rubber belt by conventional belt take-up means supports the load conveyed when the belt conveyor is making lateral turns. The carrying and return portions of the belt are supported and formed into a tubular shape by a plurality of shapers positioned along its length. Each shaper is supported from above by a monorail and includes clusters of idler rollers which support the belt.

  • Patent number: 4477765
    Abstract: A motor driven generator has a generator control unit which incorporates a programmed microprocessor to control generator operation. A generator voltage regulator utilizes the microprocessor of the generator control unit to develop an error voltage which is added to the average phase voltage of the generator, controlling the generator field current. In the event of a phase failure the generator control unit senses an abnormally high phase voltage condition, disables the average phase voltage circuit. In the event of an abnormal difference between the high and low phase voltages, the gain of the error signal circuit is reduced.

  • Patent number: 4403292
    Abstract: A control for an electrical generating and distribution system utilizing a plurality of interconnected microprocessors. An electrical system, for an aircraft for example, may have two engine driven generators and an auxiliary power unit generator with loads connected to each of the engine driven generators through generator circuit breakers. An electrical distribution bus connected through bus tie breakers interconnects the load circuits and the auxiliary generator so that any one generator can power either or both loads. Each generator has a microprocessor generator control unit responsive to the associated generator conditions to control generator operation. A microprocessor bus power control unit is responsive to distribution circuit conditions and correlates information from the generator control units, contributing to operation of the bus tie breakers, controlling distribution of power from the generators to the loads.

  • Patent number: 4024949
    Abstract: An endless conveyor apparatus is capable of transverse bending to negotiate a curve lying substantially in a horizontal plane. Pretensioned elongated elastic beads attached to the edges of a flexible endless conveyor belt accomplishes this by accommodating the difference in travel required by the bend radius differential. Specifically, the elastic beads are pretensioned sufficiently to assure support of the belt edges and resist catenary sag adjacent the inside transverse bend radius. Rollers on the frame of the apparatus engage the elastic beads supporting and driving the belt. A spine may be provided along the longitudinal center line of the conveyor and may be engaged by a plurality of pairs of guide wheels. The elastic beads are shorter than the load portion of the belt to provide for the pretensioning function. Laterally extending corrugations assist in accommodating the transverse bending action and flexible cross lines extend along the corrugations supported from the elastic beads.
