Title: Method and apparatus for quantitatively evaluating roll hardness
Inventor: ADAMS RICHARD J
IPC: G01N3/48
Filed: 1991-01-10
Granted: 1994-11-08
Abstract: A method and apparatus for testing the hardness of wound rolls, such as paper rolls, which yields quantitative information which is reproducible from roll to roll and under various conditions of testing. The apparatus can be operated much like a back-tender's stick, to simply strike the roll at a point where hardness is to be determined with a force variable between certain limits as determined by the operator using the stick. The apparatus includes an accelerometer (60) mounted in a striker (36) associated with circuitry (26) for producing signals (80, 82, 91, 94) relating to (a) the energy of the impact between the striker and roll and (b) the peak deceleration of the striker. Those signals are processed to produce a roll hardness measure, which can be correlated to a commonly used Rho scale if desired, and which is repeatable irrespective of the force used by the operator to cause the impact.

Title: Quiet bus for the busing analog and digital data
Inventor: CUFFE JOHN M
IPC: G01N29/44
Filed: 1992-08-31
Granted: 1996-06-18
Abstract: Test apparatus (10) performs non-destructive testing of an object (O) to determine if it has flaws or defects.  An ultrasonic wave (W) is generated and directed at the object.  A return wave (R) reflected by the object is received and analyzed to determine if a flaw or defect.  The return wave is converted to digital data which is stored for purposes of later analysis.  For this purpose, digital signals containing the data are routed over a quiet bus (24).  Digital signals are routed over the bus prior to generation of an ultrasonic wave to establish test parameters.  Digital noise may occur during the transmission.  A controller (22) controls routing of digital signals over the bus.  The controller inhibits the flow of digital signals over the bus during that portion of an operational cycle of the apparatus during which the ultrasonic waves are produced and return waves evaluated.  The controller allows transmission of digital signals over the bus at other times.  As a result, the ultrasonic portion of the apparatus is effectively isolated from the bus so any digital noise thereon cannot effect the ultrasonic portion of the apparatus and the test results produced thereby.

Title: Building panel assembly
Inventor: GUFFEY KENNETH J
IPC: E04D13/15
Filed: 1992-12-16
Granted: 1995-04-11
Abstract: This invention provides a panel assembly for buildings and the like comprising, in combination with structure supporting the assembly, an array of overlapping elongated metal panels, each panel including a lower edge, an upper flange, and a web including at least one outwardly protruding longitudinally extending stiffening rib.  The stiffening rib adjacent the upper flange has an elongated longitudinally extending groove and an extended bearing portion for contacting the structure when the panel is fastened thereto. These ribs provide structural support without purlins, sheathing, or the like.  A plurality of fasteners for attaching the panel assembly to the structure pierce the extended bearing portion and hold the bearing portion in contact with the structure so that when panels are affixed to the structure with the lower edge of one panel overlapping the upper flange of another panel, the groove forms a space between overlapping panels to prevent water from flowing around the stiffening rib adjacent the upper flange.

Title: Digital audio broadcasting system
Inventor: SCHUCHMAN LEONARD
IPC: H04B1/713
Filed: 1991-10-17
Granted: 2004-01-06
Abstract: A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels (stereo channels 1 to 33) to mobile receivers in an environment with severe multipath delay (80-I, 80-N) and fading. Intersymbol interference degradations caused by multipath delay (80-I; 80-N) are mitigated via an adaptive equalizer (21) in the receiver. The use of a dynamic single channel per carrier system preserves the simplicity inherent in the single channel per carrier assignment while it incorporates the ability to address frequency-selective fading by providing substantial frequency diversity. Frequency di-versity is achieved via a slow frequency hop implementation in which the assignment of a number of stereo channels to an equal number of carrier frequencies is changed periodically. In this manner, each of many independent stereo channels (stereo chan-nels 1 to 33) achieve the frequency diversity associated with a wide bandwidth by hopping among an equal number of carriers that fully occupy the bandwith. This diversify is achieved without any bandwidth expansion of the group of stereo channels rela-tive to fixed single channel per carrier assignment.
