Publication number: 20030141353Abstract: An improved sleeve style beverage carton can be processed at or near peak production rates for carton blanks and without the need for manual removal of scrap from apertures in the carton blank. The increase in production rates and efficiency is principally obtained because the stripper pins on the stripper drum used in producing the carton blank consistently and reliably puncture and remove the scrap from apertures in the die cut carton blank thereby alleviating the need to slow or stop the machine for manual removal of the scrap. Advantageously, gusset holes which are die cut in the carton blank are preferably generally trapezoidal-shaped to provide for increased surface area of the gusset hole relative to prior art configurations. The trapezoidal-shaped larger gusset holes provide for a more consistent and reliable removal of the carton material scrap from the gusset hole during production of the blank.Type: ApplicationFiled: January 31, 2002Publication date: July 31, 2003Applicant: The C.W.

Patent number: 5689238Abstract: Methods and systems for locating objects are disclosed. An electronic tag is attached to an object before storing the object. The electronic tag is identifiable by a unique response code. The response code and information pertaining to the object are recorded and the object may then be stored. To locate the object, the response code is entered into an interrogator. The interrogator sends a signal that causes the tag to emit a sound. The system thus allows for random storage of objects and is also useful for locating misplaced objects.Type: GrantFiled: March 8, 1996Date of Patent: November 18, 1997Assignee: Lucent Technologies, Inc.Inventors: Thomas C.

Patent number: 5598168Abstract: The effectiveness of a microstrip conductor antenna, such as a patch antenna, is improved at any particular frequency by making the thickness of the conductor sufficiently small to reduce shielding and losses caused by the skin effect and make currents at the upper and lower surfaces couple with each other and make the conductor partially transparent to radiation. In one embodiment the thickness is between 0.5.delta. and 4.delta.. Preferably the thickness is between 1.delta. and 2.delta. where .delta. is equal to the distance at which current is reduced by 1/e., for example 1.5 to 3 micrometers at 2.5 gigahertz in copper. According to an embodiment, alternate layers of dielectrics and radiation transparent patches on a substrate enhance antenna operation.Type: GrantFiled: December 8, 1994Date of Patent: January 28, 1997Assignee: Lucent Technologies Inc.Inventors: James G.

Patent number: 5461685Abstract: An optical passband filter having a frequency transition that is several of orders of magnitude narrower than prior optical filters includes two frequency routing devices. The first frequency routing device has one input for receiving the input signal and at least N outputs, where N corresponds to the number of frequencies that compose the input signal. The N outputs of the first frequency routing device are each coupled to inputs of a second frequency routing device. The outputs of the second frequency device each correspond to one of the selected output frequency bands into which the input signal is to be divided. A multiplexed input signal containing several different frequency channels is divided into bands that are each directed to respective outputs of the second frequency routing device. The frequency transition between the various bands may be as small as the frequency resolution between adjacent outputs of the first frequency routing device.Type: GrantFiled: October 18, 1993Date of Patent: October 24, 1995Assignee: AT&T IPM Corp.Inventors: Bernard Glance, Robert W.
