    Abstract: An improved process for the recovery of high-purity ethylene-oxide water feed streams to EO purification and MEG reaction units when both are operating in EO plants that incorporate EO Stripper bypass technology, by installing a second lights stripper to exclusively degasify the diluted EO feed to the MEG reactor, thus permitting the use of additional bypassed (gasified) EO absorbate as the diluent and resulting in a substantial increase in the total amount of EO absorbate that can bypass the EO Stripper.

    Abstract: A device for indicating the weight of an object is disclosed herein and includes a first circuit for producing an oscillatory excitation signal which is capacitively coupled to a second circuit for producing at the output of said second circuit a signal indicative of the weight of said object. In this regard, the second circuit is capacitively coupled to the first circuit by a coupling plate mounted to a support member for movement in response to the weight of said object. This output signal is applied to an electromagnetic assembly which, in response thereto, applies to said coupling plate a proportional force which is equal and opposite to the gravitational force of the supported object for terminating movement of said coupling plate. In this manner, the output signal may be monitored for indicating the weight of said object.

    Abstract: A device adapted for high-speed weighing of multiple articles, and a method for such weighing, wherein an article is supported in the vertical direction and accelerated in a horizontal direction to produce a horizontal force which is measured preferably independent of the force produced by gravity. The device includes article support means rotatable in a horizontal plane, the article support means being connected directly or indirectly to a stable support through means for sensing force only in a horizontal direction. The article is preferably maintained at a constant speed while undergoing horizontal acceleration.
