Title: Rollable roof ventilating devices and methods for use thereof
Inventor: GOSZ MICHAEL L
IPC: E04D1/36
Filed: 1998-12-16
Abstract: A ventilating system for a roof (40) made of a multi-plied weatherproof material (200). The weatherproof material includes a planar ply (204) and a second ply (208) joined such that a multiplicity of air passages (144) is defined thereby. The air passages extend generally transversely to longitudinal axes of the embodiments. Each embodiment can be transported and stored in a spiral conformation. The spiral conformation is achieved by rolling the embodiment in a direction generally parallel to the longitudinal axis. A series of embodiments include a top panel and one or more lateral vents, rolled such that the one or more lateral vents are radially exposed. When shipped and stored in a spiral conformation, the embodiment with radially exposed lateral vents is more quickly and easily installed on a roof. Another embodiment, also conformable to a spiral for shipping and storing, is advantageously used to enhance ventilation by ventilating the eave.

Title: Signal processing system for energy transfer arrangement under test
Inventor: THEISZ LAWRENCE C
IPC: G01M13/028
Filed: 1999-06-29
Abstract: Processes and apparatus for signal analysis enable "pass/fail" determinations to be made with respect to noisiness of a mechanical system under test, particularly the presence of bumps and nicks in gear train systems under test.  In a process aspect, for a gear system, a torque input is applied. A first signal responsive to the noise of the gear system under test is produced, which is converted to digital data responsive to a first correlation between the first signal and time. Peaks in the digital data are measured to determine whether they exceed a predetermined threshold magnitude. The peaks that exceed the predetermined threshold magnitude are subjected to harmonic analysis, the results being compared to gear tooth harmonics to determine whether the peaks constitute an anomaly. A load is applied to the gear system under test, the load being controllable in response to the noise signals.

IPC: A61K47/64
Filed: 2001-04-12
Abstract: The Rho family GTPases regulate axon growth and regeneration. Inactivation of Rho with C3, a toxin from Closteridium botulinum, can stimulate regeneration and sprouting of injured axons. The present invention provides novel chimeric C3-like Rho antagonists.  These new antagonists are a significant improvement over C3 compounds because they are 3-4 orders of magnitude more potent to stimulate axon growth on inhibitory substrates than recombinant C3. The invention further provides evidence that these compounds promote repair when applied to the injured mammalian CNS.
