摘要： An instrument for automatically and accurately determining the "test weight" of grain, utilizes a confined column having a constant cross sectional area with means for sequentially dumping a plurality of batches of grain from the column and weighing the batches as dumped, combined with means for detecting the height of the grain in the column before or after each dump and feeding the information as to the height and weight to a microprocessor to determine the weight per unit volume utilizing linear regression equations. The instrument also includes an infrared spectroscopic detection device for determining moisture, protein, and oil content.

摘要： An electronic weighing apparatus comprises a slit plate provided to be displaceable in association with the weight of an article being placed on a weighing pan. A photosensitive device is provided in the vicinity of the split plate for generating a train of pulses responsive to the slits in association with the displacement of the slit plate. The slits are provided on the slit plate such that the pulses are obtained from the photosensitive device only if and when the amount of displacement exceeds that corresponding to a predetermined weight value. The slit plate is further provided with a magnetic shield plate at the position before the photosensitive device detects the slits for the first time when the slit plate is displaced by virtue of an article. A permanent magnet and a reed switch are provided to be faced to each other through the slit plate at a mechanical zero point position, such that the reed switch is turned on if and when the slit plate is displaced and the magnetic shield plate is removed from the mechanical zero point position, whereby various components of the electronic weighing apparatus are energized by a battery. The pulse train obtained from the photosensitive device is counted by an up/down counter, which is initially loaded with the data associated with the above described predetermined weight value when the reed switch is turned on. Accordingly, the up/down counter starts a count operation of the pulse train, starting from the above described initial count value associated with the above described predetermined weight value.

摘要： Weighing apparatus and method. A plurality of weigh members are moveable in sequence in a continuous path. Each weigh member receives an item to be weighed and includes a member which is moveable in response to the weight of the carried item. Preferably, the moveable member is elastically deformable. When an item to be weighed is deposited on a weigh member, the moveable member moves in response to the weight and then "springs" back and so on in an oscillating fashion. The weigh members, each carrying an item to be weighed, are rapidly moved in sequence along the continuous path to a weighing location and the time, while short, is sufficient to permit oscillating movement of the moveable member to substantially cease by the time that the weigh member arrives at the weighing location. At the weighing location, electromagnetic radiation is impinged upon a boundary edge of the moveable member and a pattern of electromagnetic radiation is produced which is characterized by the position to which it moved in response to the weight of an item carried by the weigh member. In a preferred embodiment, the electromagnetic radiation is impinged upon two boundary edges, one fixed and one moving with the moveable member. Diffraction waves emanating from the boundary edges interact to form an interference pattern and the interference pattern is characteristic of the position of the moveable boundary edge relative to the fixed boundary edge. The pattern is analyzed to determine the weight of an item borne by each respective weigh member.

摘要： System for providing a digital indication of the load on a scale, utilizing a relative position transducer to produce two output signals which vary between fixed levels in response to incremental displacements of the output indicator of the scale. The two signals are phase encoded in that one of the signals leads the other, depending upon the direction of displacement. The two signals are processed to determine the occurrence and direction of each increment of displacement, and the count in a digital counter is incremented or decremented in response to each increment according to the direction of the displacement.

摘要： A spring weighing scale includes an optical detector which generates a moire fringe pattern and moves the pattern as an optically amplified function of scale tare deflection. A first of a pair of parallel optical gratings moves with a scale tare structure, while a second reticle grating remains fixed. Passing through both gratings is a light beam which projects a fringe pattern upon a photodetector array. Placement of a load upon the scale results in movement of successive fringes across the photodetectors and the sequential generation of weight indicative signals which are counted to determine load weight. Automatic zero load adjustment is effected by a displacement linkage driven by a stepping motor to provide displacement of the photodetector array along the axis of pattern movement. The motor is controlled by a counter monitor to register the photodetector array with the pattern image no load position such that a null count is produced. The linkage employs a twin parallel threaded worm and socket to provide any requisite compensatory shift of a chassis which carries the photodetector array. In a further embodiment, the photodetector chassis is supported by a pair of parallel leaf springs which bias the chassis against an adjustment worm driven by the motor. Alternately, a sine bar sliding wedge is worm driven against the bias of the leaf springs to displace the chassis.

摘要： An optical detection system for a spring scale includes an apparatus for generating a moire interference fringe pattern and detecting the pattern movement to measure scale tare deflection and thereby determine the load weight. One of a pair of ruled parallel grating sets is fixed while the other is mounted to the tare structure in alignment with the fixed set. A lamp projects the interference pattern upon a photodetector array. The placement of a load upon the scale deflects the tare structure which results in a linear movement of the projected fringe pattern across the photodetector array and the resultant sequential generation of weight indicative signals. To compensate for variations in the spring constant of selected scale springs, the linear tare deflection required to provide movement of a given number of interference fringes past a reference is adjustable. This adjustment of effective spring constant is achieved by varying the angle of the gratings of the movable grating set.

摘要： A high speed weighing scale for use in a continuous mail sorting and postage imprinting system which automatically weighs and meters each piece of mail. The system is designed to rapidly handle a large quantity of mixed mail. Mixed mail is continuously and synchronously fed in seriatim along a continuous feed path. Unsealed envelopes have their flaps wetted and sealed. All the envelopes are stopped at a weighing station where they are weighed, and the postage corresponding to their particular weight is computed. The determined postage value is used to continuously reset a postage meter which imprints the required postage upon each envelope as it arrives at a metering station. The metering and weighing functions of the system are synchronized such that the postage meter will imprint the proper postage upon each piece of mail, despite the fact that several envelopes may be simultaneously in transit along the feed path. Overweight pieces of mail are rejected from the feed path prior to their reaching the postage meter station. Metered and overweight pieces of mail are separately stacked.
