Title: Method and apparatus for testing chew-out strength of paperboard core
Inventor: TIFFIN RONALD C
IPC: G01N3/00
Filed: 1994-07-25
Granted: 1997-01-14
Abstract: The invention provides a method and apparatus for testing the chew-out strength of paperboard cores. The apparatus of the invention includes a clamping element for clamping a tubular core to prevent rotation thereof; a splined chuck element in the form of an axially tapered member having a plurality of circumferentially distributed splines for insertion into one end face of the core; and a means for applying increasing torque at a controlled rate to the splined chuck element.  A measuring means measures the torque applied to the splined chuck element.  In operation, increasing amounts of torque are applied by the torquing means until the splined chuck element shears the end face of the tube resulting in chew-out of the core.  The maximum torque force applied to the splined chuck element provides an accurate indication of the chew-out strength of the core.

Title: Atm switching system and cell control method
Inventor: KOZAKI TAKAHIKO
IPC: H04L47/80
Filed: 1994-08-18
Granted: 1999-09-28
Abstract: An ATM switching system includes PVC allocation circuits 13-i corresponding to output queues 14-i is disclosed. At the time of arrival of the leading cell of each burst data, if the output line has a room, the PVC of the burst data is stored as information for admission and identification. The subsequently-arriving cells having the same PVC identification information as the stored identification information are input to an output buffer, and the cells of the remaining burst data are all discarded. Even when a plurality of burst data compete for the same output line, the fact that all the cells other than the first-arriving admitted burst data are discarded prevents the cells from being input other than within a predetermined bandwidth and localizes the burst data affected by the cell discarding due to output queue overflow.

A logic circuit receives the outputs of all of the signal processors and provides an output alarm signal when a predetermined combination of affirmative signals is received from the signal processors.  Such logic circuit preferably works with digital signals obtained by analog-to-digital conversion.  A threshold bias adjustment may be provided for adjusting the threshold amplitude of at least one input signal so that ambient noise may be taken into consideration by the logic circuit.

Abstract: The trellis demapper, which is capable of demapping 8-PSK and 16, 32, 64, 128 and 256 QAM trellis codes, comprises respective I-channel, Q--channel and remapper RAMs, an 8-PSK demapper logic means and a MUX selects. Each of the RAMs includes a lookup table is selectively programmed for each of the QAM codes. The I-channel RAM and the Q--channel RAM, each of which has a storage capacity of 768 bits, directly forwards their respective outputs through the MUX selects as the trellis demapper output in response to a QAM trellis code which is an even power of 2 (i.e., 16, 64 or 256) being selected. In response to a QAM trellis code which is an odd power of 2 (i.e., 32 or 128) being selected, the respective outputs of the I-channel RAM and the Q-channel RAM are applied as inputs to the remapper RAM, which has a storage capacity of 320 bits, and the output of the remapper RAM is forwarded through the MUX selects as the trellis demapper output. In response to an 8-PSK trellis code being selected, the output of the 8-PSK demapper logic means is forwarded through the MUX selects as the trellis demapper output. This configuration is structurally efficient and requires minimum storage requirements compared to a trellis code demapper employing ROM storage for the 16, 32, 64, 128 and 256 QAM and 8-PSK trellis codes.
