![Hospital and Clinical Weighing Scales - Pediatric Weighing Scale Hospital and Clinical Weighing Scales - Pediatric Weighing Scale](http://www.weightcheckers.info//img/hospital_and_clinical_weighing_scales.jpg)
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+ |
