    • 169,271. Jackson, J. D. June 22, 1920. Surface and outline gauges.-A screw gauge of calliper type is provided with anvils which may be adjusted and locked, and are formed on the contact surfaces with V-grooves of thread-section, but cut straight across the face and provided with a clearance angle. In the form shown in Figs. 1 and 3, the anvils c are dovetailed into the frame and secured by conical screws p. The threads on the contact surface have a clearance angle w of about 10‹. The frame a is recessed to receive screws q, the heads h of which are graduated and bear against the outer ends of the anvils for adjusting purposes. The bow of the frame is in a plane inclined at an angle of about 120‹ to the plane of the lugs. In a " no-go " gauge, one anvil is provided with one thread only, the opposite anvil having two threads. In a modification, the anvils are secured by wedge-shaped binding: slips held in place by studs and nuts.

    • An unsynchronized acoustic or radio-frequency (RF) computed tomography (CT) imaging system with matched, but independent, continuous wave (CW) transmitters and receivers configured to radiate acoustic or RF transmissions in a plurality of vector paths through solid geologic material. A computer calculates and displays tomographic images constructed from individual acoustic or RF path signal travel time or attenuation measurements logged from registered locations from the CW transmitters and receivers after their being shuttled amongst a number of different transmitter and receiver perspectives available around said geologic material to generate data necessary for computed tomography. Each of the transmitters and receivers include independent unsynchronized crystal oscillators rated at 10-ppm or better frequency uncertainty to produce and to detect CW radio frequency (RF) transmissions.

    • Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.
