definition of weighing scale

Hospital and Clinical Weighing Scales - Pediatric Weighing Scale

This class provides for (1) scales that determine the weight of articles or material, (2) the control of the supply of material to, with or without the discharge from, a weigh chamber responsive to accumulation of a predetermined weight of the material in the weigh chamber.

Card, Picture, or Sign Exhibiting, subclass 458 for a changeable exhibitor operated or controlled by a weigher.
Measuring and Testing, subclass 296 for a weighing type liquid level gauge, and 433+, for specific gravity or density determination with a weighing feature. See the notes to Class 73 for the distribution of measuring and testing art.
Tobacco, subclasses 280+ for automatic weighers controlling the feed of tobacco to cigar or cigarette machines.
Fluid Handling, subclasses 161 and 162 for a gravitating vessel controlling a fluid pressure system and subclasses 403+ for a fluid handling system controlled by the weight accumulated fluid.
Fluent Material Handling, With Receiver or Receiver Coacting Means, appropriate subclasses for a weigher-receiver organization with handling in addition to supplying or removing receivers, or treatment subsequent to completion of a weighing phase, particularly subclass 83 for mere determination of weight of contents of a receiver.
Metal Founding, subclass 155.7 for a metal casting apparatus including control means influenced by a weight sensor.
Check-Actuated Control Mechanisms, for check controlled weighing scale subclass 339 for the rejection of coins of improper weight.
Conveyors: Power-Driven, subclass 959 for a conveyor having a weighing feature wherein there is some moving of the material besides that necessary to the weighing operation.
Classifying, Separating, and Assorting Solids, subclasses 510+ , 592+, and 645+ for means for automatically sorting articles by weight, and subclass 239 for sifting with weighing.
Traversing Hoists, subclass 283 for a traversing hoist with a weighing means which accomplishes more than the mere lifting and weighing of the load.
Dispensing, subclass 55 for constant feed from a dispenser responsive to the weight of unrestrained material already discharged, subclass 58 for means responsive to the weight of material in a container for controlling its discharge, and subclass 77 for weighing-dispensing combinations involving means to weigh material already dispensed.
Recorders, subclass 94 for a recorder operated by a weigher wherein there is included only so much of the weigher as is necessary to operate the recorder.
Agitating, subclass 18 for mortar mixing devices including means for proportioning ingredients by weight, and subclass 141 for agitation with weighing.
Thermal Measuring and Testing, subclass 14 for thermal gravimetric analysis.
Conveyors: Fluid Current, subclasses 23+ and 32+ for a fluid current conveyor including a weighing feature wherein there is some movement of the material besides that necessary to the weighing operation.
Material or Article Handling, subclass 21 for weighing with handling of that class more than that necessary to the weighing operation.
Data Processing: Generic Control Systems or Specific Applications, subclass 305 for weight responsive computer control system.
Data Processing: Measuring, Calibrating, or Testing, subclasses 101+ for weight calibration or correction system, and subclasses 173+ for weight measurement system.
Data Processing: Financial, Business Practice, Management, or Cost/Price Determination, subclass 407 , for a postage meter system including (a) a weighing device to determine the weight of an article and (b) an electrical computing arrangement to calculate a postage fee based on the determined weight; and subclasses 414+, for determining the cost per unit weight of a material by an electrical computing arrangement.
Measuring, Testing, or Signalling Instruments, subclasses 87+
