  • Patent number: 7396985
    Abstract: The invention relates to a grip for a musical instrument, particularly a band instrument which may be used in a group performance. A component of every musical performance, especially a group performance by a group such as by a marching band or drum and bugle corps, is the visual component. In the case of a horn, a visually attractive visual component would be a selective spinning or rotating motion provided by the performer, using a grip attached to the horn for allowing support of said horn in a single hand. The grip further provides an ergonomic means for gripping the horn in either one or both hands.

  • Patent number: 6715175
    Abstract: A method and apparatus for predicting load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to rapidly accelerate a rotation of the vessel, determine an amount of energy with which the vessel has engaged the relatively stationary part, compare the amount of energy with a predetermined value and send a signal indicative of an unbalance condition if the amount of energy exceeds the predetermined value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor and through manipulation of the current, determine the amount of energy with which the vessel engages the stationary part of the appliance.

  • Patent number: 6685241
    Abstract: The invention concerns a closing device for a washing machine or clothes dryer with a machine door that locks a loading opening exhibiting a closing piston mounted onto the machine door hinged to the machine housing and a lock in the area of the loading opening, whereby the lock is provided with a latching element that brings the closing piston into a latching closed position when the machine door closes and releases it to an open position when the machine door is opened. An automatic adjustment of the closing piston to the latching element when the machine door closes is achieved in that the closing piston can be adjusted horizontally to a limited extent in the door rim, and that the closing piston with its nose is alignable with the latching element in a receiving element in the door frame around the loading opening.

  • Patent number: 6658902
    Abstract: A dynamic balancer for an automatic washer includes an annular hollow first chamber. A first fluid is held within the first chamber and only partly fills the first chamber. An annular hollow second chamber is disposed adjacent to the first chamber and includes a plurality of objects disposed therein which are movable along the chamber. A second fluid is also held in the second chamber and, in combination with the solid bodies, only partly fills the second chamber. The first fluid in the first chamber produces a first balancing characteristic of the dynamic balancer. The movable objects within the second chamber produce a second balancing characteristic of the dynamic balancer. The second fluid held in the second chamber also produces a third balancing characteristic of the dynamic balancer.

  • Patent number: 6647575
    Abstract: A method for reducing displacement of a wash basket that is rotatable about an axis of rotation within a washing machine. The method comprises the steps of: mounting a balancing ring to the basket in the plane that is generally perpendicular to a rotation axis of the basket. Another step is supporting the wash basket by a tuned suspension structure to the machine and determining two resonance critical frequencies for two translational degrees of freedom and three resonance rotational frequencies for the three rotational degrees of freedom of the suspension structure. The method also comprises the step of tuning the suspension structure so that the two critical frequencies of translation each occur at or below a critical first motor speed and so that the three rotational frequencies occur at a second speed that is above the critical rotation speed.

  • Patent number: 6640372
    Abstract: A method and apparatus for determining load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to accelerate a rotation of the vessel between a series of constant rotational speeds, measure an amount of current with which the motor draws in rotating the vessel at each of the rotational speeds and during each acceleration period, compare the amount of current with a calculated threshold value for each speed and each acceleration period and send a signal indicative of an unbalance condition if the amount of energy exceeds the precalculated threshold value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor. The threshold values can further be adjusted by comparing the actual line voltage supplied to the motor with a predetermined nominal line voltage.

  • Patent number: 6642491
    Abstract: A process for controlling a cooking operation in a microwave oven as well as a microwave oven therefor. Subsequent to a heating step at full power for bringing cooking liquid to the boil, foodstuff which is to be cooked is added, whereupon continued moisture sensor controlled heating begins, initially at full power, until boiling resumes, whereupon moisture sensor controlled simmering/boiling takes place during a cooking time. During an initial time period of the continued moisture sensor controlled heating, the moisture sensor action is inhibited.

  • Patent number: 6637062
    Abstract: The invention concerns a method for operating a front-loading washing machine with a washing aggregate comprising of a tub holding a rotatably-mounted drum suspended in the machine housing so as to be able to oscillate with a midaxis descending from front to back and equipped with an imbalance sensor that changes the rotation of the drum by means of a control program when an imbalance occurs in the spin cycle. In many cases of operation involving small amounts of sensitive types laundry an improved spin result can be achieved, by attending to the preset optimum filling amounts, taking into account the weight and absorbency, and by disabling the imbalance sensor and running the spin cycle at maximum speed.
