Abstract: Systems and methods described herein are optimized for cutting sealing elements on packages using optical radiation. Packages can pass through a cutting device that applies the optical radiation to damage, vaporize, or cut the sealing element (e.g., tape) on the package. The systems and methods control several aspects of the cutting process to adjust throughput, improve efficiency, and reduce line stoppages. Systems can include an in-feed conveyor that orients packages and rejects packages that are out of specification, which can lead to issues such as jamming or damage to the equipment. Systems can include a variable-speed cut conveyor controlled by a computing system to dynamically adjust the speed of packages based upon historical cut quality, environmental measurement data, and height data related to a vertical dimension of the package.

Abstract: A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for a refining process; and (ii) adding an additive to the crude hydrocarbon.

Abstract: A speech detection system is provided with multiple speech detector sub-systems. The speech detection sub-systems employ distinct statistical methods for determining whether speech is present in an electronic communication signal received at an output terminal. For example, a first speech detection sub-system employs moving average peak signal filter, a second speech detection sub-system employing a moving average noise filter, and a third speech detection sub-system employs a variance filter. Signals from each of the filters are compared with respective threshold values, and the threshold values are provided to speech determination logic for making an aggregate speech detection decision. The speech detection system is useful for telephonic automatic gain control.

Abstract: Process and apparatus for modifying melt spun filaments after extrusion and solidification by tensioning and exposing to a heated fluid environment. By this invention it is possible to directly form a melt spinnable filamentary yarn having properties similar to those of drawn yarns.

Abstract: Uniformly drawing tows of synthetic linear thermoplastic polymer filaments between sets of feed rolls and draw rolls by saturating a tow while on the feed rolls with water at a temperature of Tg .+-. 10.degree.C and ensuring that drawing is substantially complete before the tow leaves the last feed roll.

Abstract: A process for uniformly drawing tows of poly(ethylene terephthalate) to produce high shrinkage fibres wherein the drawing is effected with the tow in a hot water saturated condition at a controlled birefringence, temperature and draw ratio. The product has initial shrinkages (as defined) of at least 5% and a high uniformity.
