Apparatus and method for measuring the weight of an object such as a letter, magazine or parcel, while the object is in motion, without using a weighing scale. The apparatus and method disclosed make use of moving, preferably vertically-oriented transport belts driven by a constant velocity, closed-loop feedback system which includes an electric motor. An object to be weighed is engaged and lifted upwards by the moving belts, increasing the load on the motor as a function of the weight of the object. The increased motor current evoked by the lifted object can be processed to extract the object's weight.

Apparatus and method for weighing moving objects

A document transfer system for receiving a cluster of stacked documents within the first end of an output holder and, by using movable partitions, advancing the clusters to the second end of the output holder, thereby permitting a next document cluster to be received within the output holder at the first end. A document cluster at the second end of the output holder is then, using extendable and retractable gates, transferred from the output holder to a separate holder for further processing.

Document transfer device for multiple pass document sorting machine

A method and apparatus for increasing the throughput of a multiple pass document sorting device that sorts documents into a plurality of output holders by automatically displacing the sorted documents within the receiving areas of each output holder into a transitional area to make the receiving areas available. In this manner a next sorting pass may be initiated, using documents from the transitional area from the output holders, without the need to empty all of the output holders before a sorting pass can be initiated.
