Abstract: A spider in an extrusion die mandrel has a plurality of internal plastic flow passages extending axially through the spider and a spider leg between each flow passage. Each spider leg has a region with a radially extending air passage and further has upstream and downstream spider parts to opposites sides of the air passage region. The upstream part is a flow splitter which splits flow of plastic along the die mandrel to the spider leg into a plurality of independent plastic streams which then flow around the air passage region in the spider leg. The downstream part of the spider leg has a plurality of flow guides staggered at different radial depths in the spider leg with all of the flow guides being directed at one another to guide the bonding of independent plastic streams after they have passed around the air passage bearing region of the spider leg.

Abstract: A system and method for conducting a multi-person, interactive auction, in a variety of formats, without using a human auctioneer to conduct the auction. The system is preferably implemented in software. The system allows a group of bidders to interactively place bids over a computer or communications network. Those bids are recorded by the system and the bidders are updated with the current auction status information. When appropriate, the system closes the auction from further bidding and notifies the winning bidders and losers as to the auction outcome.

Abstract: In a communications system implementing an in-band on channel AM (IBOC-AM) (also known as "hybrid IBOC-AM") scheme, digitally modulated signals are transmitted in a 30 kHz digital band centered at an analog host AM carrier frequency f c. The host AM carrier is assigned to the geographic area served by the communications system for AM radio broadcast. It is likely that a similar IBOC-AM scheme is implemented in an adjacent area which is assigned a second analog host AM carrier having a frequency which is either 20 kHz higher or lower than f c. In that case, the transmission of the digitally modulated signals are interfered by a similar transmission in the adjacent area.      The interference is known as "second adjacent channel interference." To reduce such interference, selected power profiles in accordance with the invention are used to allocate the relative transmission power to the digitally modulated signals in the digital band.

Title: Determination of frequency offsets in communication systems
Inventor: KREMM STEVEN A
IPC: H04B7/208
Filed: 1997-09-26
Granted: 2009-09-08
Abstract: A method and apparatus for determining frequency offsets caused by oscillator error or Doppler effects in a user terminal in a communication system. The system (100) includes at least one user terminal (124, 126) and a base station (112), or gateway (120, 122) for communicat-ing through a satellite (116, 118) with predetermined or-bital positions or patterns. A communication signal (500) is precorrected (512) for known Doppler effects, such as between a gateway and a transferring satellite, when used, and transmitted to a user terminal. The user terminal deter-mines the signal frequency relative to a reference oscillator (516, 518), and treats any detected difference as resulting completely from Doppler. The frequency difference is ei-ther transferred as data in reverse link transmissions (524, 526), or used as a pre-correction factor for such transmissions (522, 526). The frequency of the reverse link user terminal signals is measured at the gateway (528), again compensating for knowm Doppler effects, to pro-vide a nominal error measurement (530). Measured fre-quency error or offsets are then divided in half to arrive at a Doppler shift error, or divided in half and scaled to the appropriate frequency to arrive at a user terminal oscilla-tor error (532). The detected error can be transmitted to the user terminal (534) for use in correcting the oscillator output frequency, or for adjusting the timing of, or time tracking for, the user terminal. Alternatively, the detected error can be included as data in subsequent signals for use by gateways or base stations (538, 540).

Abstract: An electronic tide meter which calculates a high tide time and low tide time with accuracy, and a high tide/low tide calculating method are disclosed. A tide level estimating equation is fixed by performing calendar input and selection of a region through an input section and reading tide data of the selected region from a ROM stored with tide data for each region. First tide data is determined with a first time interval from the tide level estimating equation in the CPU, and further second tide data is determined with a second time interval shorter in time interval than the first time interval. Accordingly, from the first tide level data a range is extracted in which the sign in displacement between those of the first tide level data so that tide data at a fine time interval can be determined only for the range. From the tide level data a high tide time and low tide time is calculated with accuracy.

Abstract: A rotary die cuter for a box making machine has an abrading cylinder mounted for rotation alongside the anvil for engaging and resurfacing the blanket of the anvil on a virtually continuous basis to smooth, level and even the surface of the blanket. This resurfacing occurs during normal operation of the rotar y die cutter so no production is lost. The abrading cylinder has a sheet layer of abrasive material spirally wrapped on the surface of the cylinder and bonded thereto with adhesive material on the backside of the sheet layer. The abrading cylinder is movable towards or away from the anvil by a servo motor and gearbox. The position of the abrading cylinder relative to the anvil is determined by an encoder which sends the information to a computer or programmable controller which calculates the changing diameter of the blanket and the amount of speed chan ge that must be imparted to the anvil to compensate for its changing diameter. The computer or programmable controller is connected to a drive system of the anvil to effect the speed change.

Abstract: This invention provides a method and apparatus for applying tape tabs to a traveling web, for example, for placement of fastening tabs on a running web of disposable diapers. The invention provides a cutting roll positioned to cut segments from a continuous infeeding web of tape material against a rotating anvil. The anvil, which is traveling at a speed equal to or very close to that of the infeeding tape web, carries the tape segments to a point on its tangency where a higher-speed traveling diaper web most nearly approaches, at which point the traveling diaper web is displaced slightly toward the anvil by means of a protuberance acting against the web. This movement causes it to come into contact with the next available tape segment, which becomes adhered to the higher-speed traveling web. This process provides for operation at higher speeds, higher efficiencies, greater flexibility and lower noise levels than previous processes.
