    摘要: Input data from an XY encoder stage is continuously monitored and compared to an internally generated count as the stage is adjusted in position. The internal count is generated a single count at a time by transitions in the X-Y input data on the basis that each transition is a one-step change in encoder position. A series of one-step transitions causes both the input data and the internal count to change together, or track. If a single transition is greater than a single encoder step, the input data advances ahead of the internal count and tracking is lost, causing a comparison error. The error halts the monitoring process, activates an alarm, and holds the current input data and internal count for visual comparison in a numerical display. The operator can then remonitor the faulty portion of the stage encoder to determine the nature of the error. The transition monitor is provided with internal testing circuit for counting up and down, changing counting directions, and detecting a prewired multistep test error.

    摘要: A separator for liquids, such as oil and water, is provided. The separator comprises a tangentially-fed, cylindrical vortex generating chamber which communicates axially with a conical accelerating chamber so as to form an axially disposed vortex of the lower density liquid surrounded by the higher density liquid. Both liquids flow generally downwardly in a helical flow pattern and leave the liquid separator by gravity, the lower density liquid flowing freely through an axially disposed vortex finding tube. The axially disposed vortex finding tube may be adjusted in a plane normal to the axis of the accelerating chamber as well as in the direction of the axis of the accelerating chamber. Additionally, the vortex finding tube may contain a flexible section to permit oscillation of the mouth of the vortex finding tube in a plane normal to the axis of the accelerating chamber.

    摘要: A grouting cartridge is described for placing in a hole of a support structure. The cartridge is capable of rapidly forming a solid grout about an anchor element where the anchor element is thrust into the hole. The cartridge comprises a frangible outer tubular casing fabricated of plastic or the like and containing a uniform mixture of a water-hardenable cement and a multitude of frangible microcapsules which hold droplets of water. One or more of these cartridges is placed in the borehole, and the anchor element in a one-step operation is inserted therein, and preferably rotated, to pierce the casing and rupture the microcapsules to uniformly wet the cement to form a cement paste. The cement paste under the pressure of the anchor element flows into intimate contact with the hole wall of the support structure and into intimate contact with the surfaces of the anchor element. The cement paste rapidly solidifies forming a solid grout between the support structure and the anchor element to affix the anchor element securely to the support structure.

    摘要: The azimuth beamspread smear effect in a radar image is simulated by convoluting a terrain function with an antenna gain function for each sweep that the target object is within the antenna gain bandwidth. The initial grid map of elevation-reflectance terrain data is combined with aircraft position and antenna orientation data to provide composite terrain data required to compute a terrain function along each range arc. Each radar sweep generates a data raster of composite terrain data for the R range points within that sweep. The antenna bandwidth is a small sector, M sweeps wide, which moves across the scanned sector as the antenna rotates forming R range arcs. A constantly changing block of composite terrain data for the M sweeps and R points must be continuously maintained to generate the beamspread smear by convolution of the terrain function and the antenna function. The MxR block of terrain data is held in the form of a Fourier series for each range arc. Each range arc Fourier series requires a (2N+1) memory capacity (N sine terms, plus N cosine terms, plus one constant term). The total memory requirement for the MxR data block in Fourier series form is (2N+ 1)R. The terrain Fourier series for each point along the target range arc is multiplied by the antenna gain at that point (also expressed as a Fourier series) to provide the terrain-gain point product, or return signal power for that point. The terrain function Fourier series constantly changes as the antenna rotates, and is generated from the composite terrain data through an updating technique in which a new leading sweep is added to the MxR block and the previous trailing sweep is dropped. The antenna gain pattern is typically symmetrical and has a Fourier series with N term plus a constant. The antenna function is fixed for each antenna model, mode and operating circumstance.
