摘要： A portable bathroom scale is described wherein an optical encoder is used to determine the scale displacement in an unambiguous manner. A convenient circuit is used to transform the optical code on an encoder disc to the code needed to activate a decimal display. A mechanism is described for automatically activating the encoder and display when a person steps on the scale and deactivate the mechanism when the person steps off the scale.

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.

摘要： Liquid dye is pumped by a pump submerged therein from a supply tank through a feed pipeline and into a portable bucket set on one side of a beam balance scale, until a preselected weight of such liquid in the bucket balances the scale, whereupon the other side initiates an electrical signal and operates a relay which energizes a control circuit, activating a solenoid which, in turn, operates valve means in such feed pipeline to switch the entire flow of liquid from the bucket, back to the tank through a liquid return pipe, thereby recirculating such liquid as long as the pump is running, which agitates the liquid dye in the tank, keeps the pump cool, and avoids any need for priming the pump prior to each weighing operation.

摘要： In a computer weigher, an optical device is used to detect the position of balance of the weigher mechanism by measuring the rotary position of a drum connected to the weigher mechanism. On thedrum, a Gray code chart is arranged around the periphery of the drum with several channels extending axially. A mounting block is adjustably positioned adjacent to the drum and is used to mount fiber optics and photoelectric measuring means. For each channel of code on the drum chart, a fiber optics bundle picks up reflected light at one end adjacent to the chart and transmits it to its other end at a photoelectric sensor. Binary coded signals are generated from the sensor outputs which accurately identify each drum position.
