摘要： A system for sensing the load carried in a structural member by attaching a load cell to a neutral axis of bending. Small deflections along an arc of bending create a desirable signal level via mechanical amplification. A load sensor is adapted for mounting on an axle that deviates from a neutral axis when under a load. The load sensor comprises a reaction portion adapted for mounting on the axle and an active portion adapted for mounting to at least two points along the axle. The active portion has an amplifier arm and at least one sensor element. The sensor element is attached at a first end to the reaction portion and the sensor is attached at its second end to the amplifier arm. At least one strain gauge is mounted on the sensor element. At least one flexion web is attached to the reaction portion and to the active portion. When a load is put on the axle, flexion of the axle moves the active portion relative to the neutral axis of the axle, the active portion moves the amplifier arm, causing a curve to be formed in the sensor element, the curve being of sufficient magnitude to be calibrated by the at least one strain gauge.

摘要： A system for sensing the load on a load supporting beam of a vehicle. The system comprises an elongate sensor beam and means for releasably securing a pair of opposite end sections of the sensor beam to a load supporting beam of a vehicle. The sensor beam is secured to the load supporting beam so that a longitudinal axis of the load sensor beam is aligned with a longitudinal axis of the load supporting beam. A plurality of strain gauges are attached to a central section of the load sensor beam. The strain gauges are connected so that each of them can transmit an output signal processor.

摘要： A system for the operation of once-through boilers which utilizes variable throttle pressure over a very wide load operating range is disclosed. The system utilizes a valving arrangement permitting the turbine valve (22) to be opened to a predetermined open position, typically 70 percent of its full open position, as soon as possible during the system loading process, maintaining the turbine valve (22) in this predetermined open position while the flow of steam from the boiler is being varied by a control valve (40) and the output pressure of the boiler is varying accordingly, and then allowing the turbine valve (22) to open further from the predetermined open position when the system reaches full design pressure so as to vary the flow of steam from the boiler while the output pressure thereof is maintained substantially constant. In this manner, the boiler is operated at a variable output pressure over a very wide load operating range.

摘要： A closet bend stabilizer that receives the closet bend and is embedded into a cement slab surrounding the closet bend. The closet bend stabilizer serves to reduce the movement of the closet bend installed in the opening of the cement slab. Toward this end, the closet bend stabilizer comprises a horizontally disposed plate formed with a central opening of suitable dimension to receive the closet bend. In addition, the stabilizer includes a plurality of reduced diameter openings on each side of the central opening to improve its fixed relation within the cement slab. Below the horizontal plate and surrounding the central opening is a tapered flange to facilitate the stabilizer receiving the closet bend. The stabilizer is sealed or caused to adhere to the closet bend by a suitable adhesive.

摘要： A system for detecting the weight of a person seated in a vehicle seat includes a pair of load sensor beams. Each load sensor beam has an intermediate section extending between a pair of opposite end sections. The opposite end sections of the load sensor beams are connected to a base frame of the vehicle seat. The load sensor beams are also connected to a seat pan of the vehicle seat that is positioned adjacent the base frame. The end sections of the load sensor beams are connected to opposite sides of the seat pan so that a plurality of loads generated by the weight of a person sitting on a seat cushion carried by the seat pan are transmitted to the intermediate sections of the load sensor beams. At least one sensor is mounted on the intermediate section of each load sensor beam for outputting signals representative of the plurality of loads generated by the weight of the person sitting on the seat cushion.
