Title: Resonant ultrasound spectroscopy
Inventor: MIGLIORI ALBERT
IPC: G01N29/12
Filed: 1991-09-19
Abstract: ABSTRACT      A resonant ultrasound spectroscopy method provides a unique characterization of an object  (10)  for use  in distinguishing similar objects  having  physical  differences  greater  than  a predetermined tolerance.  A resonant response spectrum is obtained for a reference object by placing excitation (14) and detection (16) transducers at any accessible location on the object.  The spectrum is analyzed to determine the number of resonant response peaks in a predetermined frequency interval.  The distribution of the  resonance  frequencies  is  than  characterized  in  a  manner effective to form a unique signature of the object.   In one characterization, a small frequency interval is defined and stepped through the spectrum frequency range.   Subsequent objects are similarly  characterized  where  the  characterizations  serve  as signatures effective to distinguish objects that differ from the reference object by more than the predetermined tolerance.

Abstract: A microphone mask to be worn in front of the mouth of an underwater diver has a microphone assembly and a teethpiece assembly mounted in a rubber waterproof enclosure. The enclosure has an air passage extending from an inlet opening to a rear outlet opening. The teethpiece assembly includes a plastic insert with a vertical plate mounted in the enclosure. The vertical plate has openings for the air passage as well as to allow sound to travel from the diver's mouth to the microphone assembly. A teeth member extends rearwardly out of the outlet opening into the diver's mouth where it is held between the diver's teeth. The teeth member is connected to the insert by resilient spring members which draw the enclosure rearwardly against the diver's face. There is a sealing surface around the outlet opening, and this seals it around the outside of the diver's mouth. This eliminates the need for a headband and facilitates the use of the microphone mask for the combination of breathing and speaking.

Title: Swirl ring and flow control process for a plasma arc torch
Inventor: COUCH RICHARD W JR
IPC: B23K10/00
Filed: 1991-04-23
Abstract: Abstract Of The Disclosure A process and apparatus for reducing wear of an electrode in a plasma arc torch involves providing a substantial pressure drop in a flow of plasma gas from the torch to a plasma arc chamber defined by the electrode and a nozzle.  The pressure drop is immediately before the plasma arc chamber.  There is also a small, localized supply of the plasma gas located between the pressure drop and the plasma chamber.  The supply is sufficient to stabilize the arc when the gas flow is cut off upstream of the pressure drop and the arc current is cut off very shortly thereafter.  The pressure drop is small enough to permit an adequate flow of plasma gas to the plasma arc chamber during normal operations, but large enough to isolate residual gas in the torch from the plasma arc chamber when the arc current is cut off.  The apparatus is preferably a swirl ring with an annular pre-chamber fed by a set of choke holes to feed gas to the chamber and create the pressure drop.  A set of swirl holes feed gas from the pre-chamber to the plasma arc chamber.     4436m

Title: Digital phase and amplitude modulator
Inventor: BENNETT STEVEN J
IPC: H04L27/36
Filed: 1993-01-22
Abstract: ABSTRACT           A digital modulator for modulating a stream of incoming data bits in which at least each one of the bits corresponds to a symbol.  The modulator includes storage for each incoming set of symbol bits, where there is at least one bit in each set, of "n" successive symbols where "n" is a positive integer with a value greater than or equal to 1, with the oldest stored set being discarded upon the arrival and storage of a next set of symbol bits.   Memory stores sample values corresponding to a modulated symbol impulse response for each of a predetermined number of symbols wherein the modulated symbol impulse responses each extend over "n" symbol periods.   Sample values over one symbol period are retrieved from the memory for overlapping portions of each of the modulated symbol impulse responses stored in the storage. An adder sums the sample values which correspond to each other in time for each of the modulated symbol impulse responses corresponding to the received symbols.  A converter converts summed digital sample values to an analog signal for subsequent transmission.

Abstract: ABSTRACT   A winding device for sheet material such as paper, cardboard and the like includes at least two axis-parallel support elements for the sheet material being wound, which extend at least over the length of the winding and of which at least one of the support elements is a carrier roll. The other of the at least two support elements has a rigid carrier which guides the winding over a sheath arranged in a rotating manner around the carrier.

The carrying shoe is provided with a concave bearing surface whose radius of curvature essentially corresponds to the maximum diameter (T) of the winding including the sheath wall thickness. The position of the carrying shoe can be adjusted as the diameter of the winding increases to reduce linear pressure on the winding allowing comparatively large diameter windings to be formed while avoiding the formation of disruptive spots or breaks in the winding.
