摘要： The present invention relates to a weighing device (1), in particular price labelling device or checkweigher, having a scale for weighing a product in a weighing section (AW), having a conveying device (4) for transporting the product (3) along a conveying region (F) from a start position (Pstart) over the weighing section (AW) to a destination position (Pdestination). To simplify a calibration to compensate for a static-dynamic offset, the invention proposes that the weighing device (1) further has a control device (5) which is configured such that the conveying device (4) can be automatically stopped during its operation in a direction from the start position (Pstart) to the destination position (Pdestination) and then can be automatically operated in a direction from the destination position (Pdestination) to the start position (Pstart). Furthermore, the invention relates to a corresponding method for weighing a product (3).

摘要： Described are systems and techniques configured to compensate for noise in output of weight sensors which may determine the weight of an item. In one implementation, a mobile cart may be configured with a first weight sensor and a second weight sensor. A noise component and a signal component in the output of the first and second weight sensors are determined. The signal component may be processed to determine the weight of the item.

摘要： A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.

摘要： The present invention is to provide a platform scale including a plurality of component force damping devices assembled therein for making high precision weighing. The platform scale for weighing an object to be weighed by supporting a support member that supports the object to be weighed by a plurality of load detection units 301,302 includes at least four component force damping devices 321˜324, each comprising an arrangement of a plurality of needle bearings disposed in parallel and a pair of opposed plates for sandwiching the arrangement of the needle bearings 63 so that the pair of plates make a relative movement in a direction of the arrangement of the needle bearings. The four component force damping devices 321˜324 are in contact with the support member at four locations that form a rectangle. Directions of the relative movement of any two component force damping devices locating at the same side of the rectangle are different, while directions of the relative movement of any two component force damping devices at diagonal locations of the rectangle are identical. Even in case of bending of the support member in any direction, the component force damping devices are able to release the horizontal component force due to such bending.

摘要： A method and apparatus whereby livestock and poultry are administered feed additives in their feed ration. The apparatus stores additive concentrates separately until just prior to use, then on demand dispenses the additive concentrates into one or more weigh hoppers for weighing therein. The weighed contents of the weigh hoppers are discharged into a liquid carrier within a mixing vessel where the dispensed additives are diluted, suspended, and dispersed by mixing. The resulting carrier-and-additive slurry is pumped to a receiving station for mixing with a feed ration. The weighing components are isolated from movements that would affect additive weight determinations during the weighing process so that accurate measurements of additive weights are obtained. Dispensing and weighing of multiple additives within a single weigh hopper are sequential. Each additive may be weighed and discharged from the hopper individually or cumulatively with other additives. With multiple weigh hoppers, dispensing, weighing and discharge of additives from the different hoppers can occur simultaneously or independently. A programmable control can program the apparatuses for dispensing either entirely on a weight basis, partly on a weight basis and partly on a metering basis, on a weight-compensated metering basis, or entirely on a metering basis if the weighing means malfunctions.

摘要： In an analytical balance with a pan and a four-bar mechanism which keeps the balance pan parallel horizontally during its vertical travel, the one vertical side of which is held fast to the housing, the other vertical side of which, in the form of a coupling piece, carries an extension which receives the pan, and both horizontal sides of which are connected in an articulated manner by an upper and a lower rod to the vertical sides, whereby the four-bar mechanism is loaded by the restoring force of a load converter, the extension (16) which receives the pan (17) is L-shaped, the horizontal L-shank (pan arm) (16") carries the pan (17) rigidly connected to its free end and the vertical L-shank (bearing arm) (16') is mounted on the bar (18'") of a U-shaped arm bearing (18) which projects above and below over the vertically movable end (9) of the four-bar mechanism (5, 6, 7, 8, 9) with its two horizontal U-shanks (18, 18") in the rod planes and is rigidly fastened to it in two vertically superposed bearings (118'). Such a construction avoids the introduction of damaging torques from the extension (16) and the balance pan (17) into the sensitive parallel guide (5, 6, 7, 8, 9).

摘要： An assembly which involves a ratchet wheel adapted to be rotated by incremental steps to drive a shaft connected thereto. A rotatable pushbutton is mounted through a hole in the chassis and is connected to a rod to which a flexible pawl is mounted parallel to the rod. When the pushbutton is in one rotary position, inward pressure strokes on the pushbutton cause the pawl to engage teeth in one region of the ratchet wheel causing it to move in a clockwise direction. When the pushbutton is rotated 180.degree. to a second rotary position, each inward push on the pushbutton causes the pawl to engage respective teeth in another region of the wheel thereby moving the wheel incrementally one step in a counterclockwise direction.
