Title: Web inspection and repair machine with web indexer device
Inventor: PRITTIE ALLAN R
IPC: B65H26/02
Filed: 1996-09-04
Granted: 2000-07-18
Abstract: A device for the inspection and repair of a roll of web material includes an unwind mandrel, a rewind mandrel, an inspection area and a splice area. A flaw in the web is detected at the inspection area, whereupon the web is braked to a halt. Where the splice area is adjacent to or coincident with the inspection area, the flawed portion of the web can pass well beyond the splice area before the web comes to a halt. Provided herein is a web-indexer device that includes a reciprocating indexer shuttle having idler rolls mounted thereon, with further idler rolls mounted to the machine such that the web material can be strung between them in a substantiallyboustrophedonic configuration.  Control means are provided to allow the operatorwho has caused the web to be braked to a halt upon detecting a flaw, to move theindexer frame so as to retrieve a portion of the web so as to bring the flaw back to the splicing station for repair, without having to reverse the rotational direction of the unwind mandrel or the rewind mandrel.

Abstract: The detection of fingerprint feature is performed on the basis of a directional distribution of fingerprint obtained by setting a plurality of points on a circle having a center corresponding to a mark point on a directional pattern of ridges, obtaining inner products of vectors indicating tangent lines and vectors indicating ridges at the respective points and providing a distribution of the inner products as a directional distribution of ridges, in the following manner. That is, as the first method, Fourier expansion means Fourier-expands the directional distribution of ridges and outputs Fourier coefficient every frequency component, power calculation means calculates power of every frequency component on the basis of the Fourier coefficients and power determination means detects the fingerprint feature on the basis of the power of every frequency components.      As a second method, smoothing means divides the directional distribution of ridges into a plurality of partial distributions and smooths the respective partial distributions and zero cross detection means detects the number of changes of value of the plurality of the smoothed partial distributions from positive to negative or negative to positive as the number of zero crossings and detects the fingerprint feature on the basis of the number of zero crossings.

Title: Thermally-driven ion-exchange process for lithium recovery
Inventor: LEAVITT FREDERICK WELLS
IPC: B01J39/14
Filed: 1996-10-24
Granted: 2000-06-06
Abstract: Ions (e.g. lithium) can be removed or recovered from brines containing those ions and optionally one or more other ions (e.g. other alkali metal ions) by the use of a temperature-swing, ion-exchange process employing an ion-exchange material.  The process depends on a change in the selectivity coefficient of an ion exchange material for the ions desired to be recovered with a change in temperature, resulting in desirable ions being relatively selectively released at one temperature and undesirable ions being relatively selectively released at another temperature.  The process of the invention can be used to effect the separation of any ion (or set of ions) from another ion or from a set of ions wherein the selectivity coefficient for one ion (or set of ions) has a substantial temperature dependence, compared to that for the other ion (or set of ions).

Abstract: An iron-type golf clubhead includes a blade, a hosel, and a junction. The blade includes a rearwardly facing blade cavity, and the junction includes a rearwardly facing junction cavity that is coextensive with the blade cavity. A graduated weight pad is located within the blade cavity and preferably has a height, in a direction perpendicular to the blade face, that varies in a toe-to-heel direction, and which may also vary from the top to the bottom of the club. The junction cavity may also include a negative weight cutout that extends below the junction cavity floor and that represents a continuation of the profile of the weight pad, in effect forming a negative weight pad. The junction cavity and weight pad act to move the center of gravity outwardly toward the toe, and also to increase the sweet spot on the outer, toe portion of the clubhead.

Abstract: An object of the invention is to provide for a telephone answering machine which reduces a charge for a call.  In a telephone answering machine 15, a caller ID extracting part 6 analyzes a call incoming signal and extracts an area code as ID information regarding a caller.  A transmission period memory part 11 stores area codes and transmission periods per unit charge in correlation to each other in advance.  An ID checking part 7 checks the area code extracted by the caller ID extracting part 6 against the area codes stored in advance in the transmission period memory part 11, and a transmission period reading part 8 reads the transmission period which corresponds to the matching area code, in accordance with the checking result.          A response message memory part 12a stores transmission periods in correlation with response messages in advance.  A transmission period checking part 9 checks the transmission period read by the transmission period reading part 8 against the transmission periods stored in the response message memory part 12a.  A response message reading part 10a reads a response message associated with the transmission period judged as matching on the basis of the checking result.  The read response message is reproduced by a reproducing part 4 at a reproduction condition set in a reproduction control part 14, and outputted to a telephone line network through a network control part 2.  The caller ID extracting part 6 analyzes a call incoming signal and extracts a telephone number as ID information regarding the caller. An operation code of a telephone answering machine 21, associated with the telephone number of the caller, is read to execute an operation of the operation code.  The operation code includes a code for designating a remote control mode.

Abstract: A vending apparatus ensures that the delay between a customer's selection of an article, and the dispensation of the selected article, is minimized, preferably to less than a predetermined delay, regardless of the point in a multi-article vending cycle. The reduced selection-dispensation delay is achieved through use of a "memory and learning" feature. The "memory and learning" feature is predicated on a recall and/or analysis of the relative times of occurrence of one or more previous dispensations, so that the apparatus' present position in the multi-article vending cycle is determined. The "memory and learning" feature allows the vending apparatus to anticipate how long the article dispensation mechanism should run after the present dispensation, to strategically poise the mechanism for a subsequent dispensation having an optimum selection-dispensation delay. Also disclosed are systems and methods for ensuring that articles are dispensed at a proper temperature, even after a "sold-out" condition is corrected; and for sounding an alarm if a person jars the vending apparatus in an attempt to improperly jar an article from the vending apparatus.

Abstract: L'invention concerne un appareil (108) et un procédé de régulation d'un transducteur ultrasonique (107a) comprenant de préférence un circuit générateur de signaux (502), un circuit de détection de signaux (504), un circuit modulateur (506) et un circuit de polarisation (508). Le circuit générateur de signaux donne un signal d'attaque à impulsions au transducteur ultrasonique. Le circuit de détection de signaux détecte la tension (510) et le courant (512) du signal d'attaque. Le circuit modulateur fournit un signal de régulation de fréquence (516) et un signal de régulation d'énergie (514) au circuit générateur de signaux de régulation correspondant à une différence de phase détectée entre la tension détectée et le courant détecté du signal d'attaque (503). Le signal de régulation de fréquence et le signal de régulation d'énergie servent à régler respectivement la fréquence et le niveau d'énergie du signal d'attaque. A l'intérieur du transducteur, un élément mobile en contact avec un liquide est positionné de préférence à un niveau correspondant à celui d'un signal de polarisation en courant continu fourni par le circuit de polarisation. Lorsqu'on règle le niveau du signal de polarisation en courant continu, le débit du liquide est réglé. Lorsqu'on applique le signal d'attaque au transducteur, la viscosité du liquide est réglée, ce qui établit un deuxième débit du liquide. Lorsqu'on change la fréquence et le niveau d'énergie du signal d'attaque, un troisième débit du liquide est établi.
