Granted: 1995-07-04
Abstract: An easy open flexible bag containing one or more stacks of flexible articles maintained in a state of compression in a direction substantially parallel  to their  thickness.   For products  such  as disposable  absorbent  baby  diapers,  catamenial  pads,  incontinent briefs and the like, the degree of compression within the bag may be as much as 50% or more when compared to the uncompressed thickness of the  stack  of  articles  in  question.   In  a  particularly  preferred embodiment,  the  bag  totally  encloses  the  stack  or  stacks  of compressed flexible articles and exhibits a substantially rectilinear shape.  The bag preferably includes an integral carrying handle.  The end panels and at least one pair of either the front and back or the top and bottom panels of the bag are subject to tension imposed by the stack of compressed flexible articles.  This leaves at least one pair  of  panels,  preferably  the  top  and bottom  panels,  in  a substantially  untensioned  condition.   One  of  the  substantially untensioned  top  and  bottom  panels  contains  an  easily  visible, unobstructed tear initiating device which comprises a portion of the easy open device for the bag.   The tear initiating device can be readily activated by the end user's fingers to create an aperture traversing at least one corner of the bag.   Partially pre-erected easy  open  flexible  bags  of  the  present  invention  are  filled  by over-compressing  the  flexible  articles  to  a  dimension  which  is smaller than the interior of the bag and thereafter allowing the articles to expand slightly once they have been inserted within the bag.  Preferred apparatus for compressing the flexible articles and inserting  them  into  partially  pre-erected  flexible  bags  of  the present invention are also disclosed.

Title: Electronic article surveillance tag and method of deactivating tags
Inventor: FRONING ROBERT LEE
IPC: G08B13/24
Filed: 1990-07-31
Granted: 2000-01-25
Abstract: A deactivatable tag useable with an electronic article surveillance system and method of making such a tag. The tag includes a resonant circuit and a provision for promoting the permanent deactivation of the tag. The solution according to the present invention has been to render the deactivator more difficult to operate. A higher level of excess energy is applied to the resonant circuit before the breakdown material breaks down. This higher level of energy in the resonant circuit is applied to the improved deactivator and operates the deactivator much more completely. This arrangement promotes permanent deactivation of the resonant circuit to prevent the resonant circuit from becoming active again or "coming back to life" as time passes. The deactivator adjacent the resonant circuit can include a vacuum metalized conductive coating.

Filed: 1990-09-18
Granted: 1998-02-03
Abstract: A device to determine phase transitions by means of thermal analysis using a sample taken from molten metal comprises an expendable measuring probe with a solidification chamber into which the molten metal flows, whereby the solidification chamber contains a thermocouple with which the course of cooling is recorded over a specific time period.  According to the invention, the side walls of the solidification chamber 3 comprise a metal casing 4 that completely surrounds the chamber and extends lengthwise of the measuring probe 1.  Both open ends of the casing 4 are covered by plugs 5,6 made of a material whose heat conductivity is substantially less than that of the casing material.  The casing is completely surrounded by a covering 2,8 which is made of a material whose heat conductivity is substantially less than that of the metal casing.  The supply orifice for the molten metal comprises a quartz pipe 9 surrounded by a metal pipe 10.  According to the invention, the mass of the casing 4, which results from its height (h) and the thickness of its walls (b), is proportioned so that the heat which is given off by the molten metal flowing into the solidification chamber and absorbed by the metal casing produces, in the area of the thermocouple, an equilibrium temperature which approximates the solidification temperature as closely as possible.

Title: High efficiency power converter employing a synchronized switching system
Inventor: ENG JOHN E
IPC: H02M3/158
Filed: 1990-12-21
Granted: 1996-01-09
Abstract: A synchronized switching system for use in a power converter. A pulse-width modulation controller is provided to alternately turn on and off a switching device and control the on/off duty cycle. When the switching device is turned off, initial commu-tating or flyback current from an inductor is conducted by a protective diode connected to ground. The diode is paralleled by a more efficient secondary switching device that is synchronized to conduct during the nonconduction period of a main switching de-vice. A sense winding is added on the inductor for synchronizing the secondary switching device. A digital logic circuit controls the conduction time of the secondary switching device based on signals from a pulse-width modulation controller and from the sense winding of the inductor. After the main switching device has been conduct-ing for the required time, the pulse-width modulation controller turns it off. The digi-tal logic circuit senses the voltage level on the inductor and causes the secondary switching device to conduct, just after the main switching device stops conducting. The digital logic circuit prevents the main and secondary switching devices from con-ducting simultaneously.

Title: Wireless telecommunication systems
Inventor: VANNUCCI GIOVANNI
IPC: H04L7/00
Filed: 1991-10-31
Granted: 1996-09-03
Abstract: The present invention overcomes the prior art limitations by dividing a coverage area into very small regions or cells. The inventive system can be built as an adjunct to a wired telecommunication system such as a PBX. Advantageously, because of the relatively small size of each cell, transceivers in the inventive system can use very low transmission power, compared with a pico-cellular communications system, to communicate with a fixed transceiver. In addition, because of the relatively short distance between any two transceivers are reduced and, therefore, the multipath distortion which can affect the received signals is substantially reduced.  A concomitant problem normally associated with relatively small cells is the need for a switching system which can accommodate the large amount of switching or handovers requiredto accommodate the various mobile units as they move from one cell to another. In accordance with the present invention, this problem is solved by a switching technique which is not centralized in the PBX but, rather, is effectively distributed among the individual fixed-call terminals.

Title: Digitally controlled element sizing
Inventor: DUNLOP ALFRED E
IPC: H03H11/24
Filed: 1992-06-11
Granted: 1997-10-21
Abstract: Effective control of impedance values in integrated circuit applications is achieved with an integrated circuit transistor whose size is digitally controlled. The digitally controlled size is achieved, for example, with a parallel interconnection of MOS transistors. In one application, the digitally controlled transistor serves as a controlled impedance connected to an output terminal of an integrated circuit. In that application, a number of transistors are enabled with control signals, and the collection of enabled transistors is responsive to the input signal that normally is applied to a conventional transistor. In another application, where the digitally controlled transistor serves as a controlled impedance at the input of a circuit, only the control signals that enable transistors and thereby determine the effective developed impedance are employed. In still another application, the digital control of the transistor's size is employed to controlthe speed or power consumption of the effective transistor. Such control is exercised to erase the manufacturing variability of the integrated circuit. Alternatively, such control is exercised as part of a feedback control of the operational characteristics of the entire circuit. In the feedback control application, the digital signals that control the transistor's size are obtainedfrom an assessment of the circuit's operation. In the manufacturing variability control application, the digital signals that control the transistor's size are obtained from a measure of the integrated circuit's paramenters relative to a reference element.
