A seat weight sensor for detecting the weight of a seat occupant. The weight sensor has a case mounted between a seat pan and a seat member. One or more strain gauge resistors are mounted in the case. The resistors generate an electrical signal in response to the case being stressed by the weight of the seat occupant. The electrical signal changes as a function of the weight of the occupant. A fastener passes through the seat member, the case, and the seat pan. The fastener secures the sensor between the seat pan and the seat member. The case is adapted to transfer to the strain gage resistor the weight of the occupant up to pre-determined level. The case prevents the strain gage from receiving weight beyond that of the pre-determined level such that the sensor is not damaged by an excessive load. The case also allows the weight sensor to be insensitive to off-axis forces that might otherwise contribute to inaccurate weight readings.

The present invention relates to the automatic balance adjusting centrifuge that enhances the efficiency of space utilization by simplifying the structure as well as supports a precise movement by improving the structure of the balance weight transport apparatus in the automatic balance adjusting centrifuge that compensates the unbalance of the centrifugal force by transferring the balance weight equipped in the rotor rotational arm.According to the automatic balance adjusting centrifuge of the present invention, the structure is simplified as well as the precise and exact transfer of the balance weight is possible by connecting the balance weight with the axis of the motor directly and adopting the length sensor. Furthermore, the efficiency of space utilization is enhanced because the axis of rotation of the balance weight transfer motor is in radial direction of the rotational arm.

The invention alleviates wear on a plow moldboard by achieving a reduction in the effective weight of the moldboard on the roadway. One or more elastic links are interposed between the moldboard and the lifting arm which elevates and lowers the moldboard. The elastic links may be tensioned to such a degree that they serve as a counterweight for the moldboard, transmitting all or most of its weight to the lift arm and the plowing vehicle. The effective weight of the moldboard is thus reduced to such a degree that the lower edge of the moldboard bears against the roadway with little or no force, and it skids or slides along the roadway rather than grinding against it.
