IPC: B29C65/74
Filed: 1997-09-30
Abstract: The invention provides apparatus for producing preselected lengths of rope from a supply of thermoplastic rope, and includes a rope feed system for advancing rope longitudinally along a rope path and a guillotine assembly coupled to the feed system. The guillotine assembly has a thermally conductive blade support mountedfor reciprocal movement orthogonally with respect to the rope path, and a thermally conductive blade removably attached to the blade support. The blade is in good thermal contact with the blade support and movable with the blade support between a first position clear of the rope path and a second position in which the bladecrossed the rope path. An electrical heating element is attached to the blade support to heat the support and thereby heat the blade to a temperature sufficient to fuse the rope locally. A blade actuator is coupled to the chassis and to the blade support for reciprocating the blade support and a control system is coupled to the rope feedsystem and to the guillotine assembly to actuate the rope feed assembly and the guillotine assembly. As a result, the blade engages the rope and applies heat so that the blade passes through the rope as the rope is softened and the sides of the blade fuse the rope ends to thereby fuse and sever the rope. The cycle is repeated in accordance with a counter in the control system and the lengths of the severed ropes are preselected in the control system.

Abstract: A method and apparatus for recognizing an identifier entered by a user. A caller enters a predetermined identifier through a voice input device or a touch-tone keypad of a telephone handset. A signal representing the entered identifier is transmitted to a remote recognizer, which responds to the identifier signal by producing a recognized output intended to match the entered identifier. The present invention compares this recognized identifier with a list of valid reference identifiers to determine which one of these reference identifiers most likely matches the entered identifier. In performing this determination, the present invention employs a confusion matrix, which is an arrangement of probabilities that indicate the likelihood that a given character in a particular character position of the reference identifier would be recognized by the recognizer as a character in the corresponding character position of the recognized identifier. This determination yields an identifier recognition probability for every reference identifier, and the present invention selects the reference identifier with the highest identifier recognition probability as most likely corresponding to the entered identifier.

Inventor: MACDOUGALL TREVOR W
IPC: G01R33/032
Filed: 1996-09-12
Abstract: A Faraday effect current sensor uses a plurality of concatenated field sensors, with a single light source and a single detector. At least two Faraday effect sensing elements (single mode sensing fibers) are used, preferably at least three, the sensing elements being interconnected by fusion spliced, polarizing fibers. The sensing fibers may be oriented generally straight, and arranged to form a regular polygon, e.g., an equilateral triangle for a three-element sensor. The locations of the splices between the sensing fibers and the polarizing fibers may further be advantageously arranged such that the sensing fibers form a substantially closed path which may be placed about the current-carrying conductor. The linearity of the sensor response may be improved by selecting an appropriate value of the bias angle of each sensing element optimally equal to arctan[1/.sqroot.(2n-1)]  where n is the number of sensing elements.    The present invention may also be adapted for use as a differential current sensor wherein each sensing element is housed in a separate package allowing the elements to be placed about different conductors at a Y-branch, or about a single conductor at different locations.

Title: Method and apparatus for creating controlled flows in two mutually separable solutions
Inventor: SAARENP TIMO
IPC: B01D17/028
Filed: 1997-04-29
Abstract: The invention relates to a method for settling the dispersion formed in the mixing unit of liquid-liquid extraction, for controlling solution flows and for creating pure solutions in the separation part.      According to the method, the flow speed of the organic solution phase is adjusted to be clearly higher than the flow speed of the aqueous solution phase, in which case in order to prevent border flow turbulence caused by the speed difference of the solution phases, the water drop dispersion layer left in between the separating solutions is adjusted to extend as far as the discharge end of the separation part. In order to settle the solution phases, at the front end of the separation pan there are arranged at least three spots where the dispersion and the already settled solutions are made to flow through a picket fence forming a restricted transversal surface, in which case the first restricted transversal surface turns the flow fed into the separation part to follow the longitudinal direction of the separation part, and the second picket fence in the flow direction forming a restricted transversal surface allows the settled aqueous solution phase to flow freely in the bottom part of the separation part. The invention also relates to an extraction apparatus according to the method.
