Abstract: Metering dispensers include a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Heat from an exothermic chemical reaction(s) is employed to superheat and/or reheat steam generated by a light water nuclear reactor (LWR). The use of such a source of heat enables the selection of a temperature for the heating limited by thermodynamic considerations that eliminates equipment failures due to overheating the heater tubes.
