An orbital shaker with a balancing device that automatically and passively compensates, without supply of external energy, forces and moments which are caused by imbalance and arise during operation, in particular as a result of a possible variable loading (mass, geometry of the containers, properties of the contents) and variable operating parameters (speed of rotation and shaking radius). The balancing device can be designed such that only the unbalance forces (static balancing) and/or the unbalance moments (dynamic balancing) are compensated.

A balancer includes a balancer housing having an annular channel defined therein, at least one mass movably disposed in the channel, and at least one magnet coupled to one side of the balancer housing to restrain movement of the mass along the channel when rotational speed of a drum of the washing machine is within a predetermined range. The magnet includes a plurality of unit magnets arranged in a circumferential direction of the balancer housing.

A balancer for a wheel and tire assembly includes one or more tubes 101 containing a movable mass 104. The tube or tubes is/are mounted to a resiliently deformable support 102 with an outer dimension that substantially matches an inner dimension of the tire. the support being arranged to position and support the or each tube within the tire. The/or each tube may be annular. The support may be formed from a plastics mesh 102.

A balancer of a washing machine having improved balancing performance. The balancer includes a balancer housing having an annular channel therein, at least one mass movably disposed in the channel at least one groove recessed in an inner surface of the balancer housing so as to accommodate the mass, and at least one magnet coupled to an outer surface of the balancer housing to restrict the mass accommodated in the groove when an RPM of the drum is within a specific RPM range. The magnet is configured as a plurality of N poles and S poles which are arranged alternately, and the outermost pole of the magnet among the plural N poles and S poles has a relatively shorter length than another adjacent pole.

A combination vehicle tire sensor assembly and in-tire wheel balancer is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. The combination comprises a flexible mounting cable secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable inside the pneumatic tire a spaced distance from the sensor assembly. A substantially hollow balancer belt resides inside the pneumatic tire adjacent the sensor assembly and counterweight, and defines a circumferentially-extending exterior groove designed for receiving and locating said mounting cable, and a circumferentially-extending interior cavity adapted for loosely containing a wheel-balancing medium.

An in-tire vehicle tire sensor assembly is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. A flexible mounting cable is secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable a spaced distance from the sensor assembly.

The present invention relates to a laundry treating apparatus. The laundry treating apparatus according to an embodiment of the present invention includes a control unit which controls the tub to rotate at a first speed in a case of a blanket dehydration mode, to rotate at a second speed lower than the first speed so that the plurality of balls are dispersed when amount of eccentricity in the first speed rotation is equal to or greater than a first reference value, and to rotate at a third speed higher than the first speed when the amount of eccentricity in the first speed rotation is less than the first reference value. Accordingly, in a blanket dehydration mode, it is possible to stably perform dehydration by preventing the plurality of balls from operating unbalanced.
