Abstract: An engineering method of providing a lining onto the internal face of conduits for gas, city water, etc. that are burled underground.  This lining work shall entirely be done from the portions exposed above ground.  The distance of the supply pipe to the service tee is measured.  The lining tube is set to a length that is slightly longer than this distance.          The lining tube is turned inside out inside the supply pipe.          As a result, a slightly longer length of non-reverse portion is left inside the supply pipe by the service tee.  This non-reverse portion is helpful when cutting the rewinding tape that is tied to the lining tube after the insertion of a cutter.  Next the heating tube shall be reversed similarly, and a hot water hose is inserted for circulating hot water in the heating tube.  The aforesaid lining tube coated with the thermosetting adhesive is bonded onto the internal face of supply pipe.  Next the heating tube is pulled out and the rewinding tape of the lining tube is cut and removed.  A fusion-cutting heat rod is inserted for fusion-cutting the tip of lining tube for an opening.  Then the fusion-cutting heat rod is pulled out.

Title: Method for determining air mass in a crankcase scavenged two-stroke engine
Inventor: FRANK RICHARD M
IPC: F02D41/18
Filed: 1991-02-05
Abstract: METHOD FOR DETERMINING AIR MASS IN A CRANKCASE SCAVENGED TWO-STROKE ENGINE                   Abstract of the Disclosure A method is described for determining the cylinder mass of air available for combustion in a crankcase scavenged, two-cycle engine, based upon the Ideal Gas Law relationship and indications of pressure, volume, and temperature of air in the crankcase chamber, at predetermined points in the engine operating cycle.  This is achieved by first determining the mass of air trapped and compressed in a crankcase chamber, and thereafter, determining the residual air mass remaining in the crankcase after the transfer of air to the associated combustion chamber.  Then, the actual air mass transferred to the combustion chamber is determined as a function of the difference between the trapped and residual air masses.  Engine trapping efficiency can be used to correct for air leakage from the combustion chamber prior to cylinder exhaust port closure.  The volume of the air within the crankcase chamber is derived as a function of engine cycle position, with crankcase air temperature being derived as a function of intake air temperature.  Air pressure in the crankcase is monitored with a pressure transducer.

Abstract: An active adaptive noise canceller (20) that inserts delays (21) in the weight up-date logic (22) of an adaptive filter (13) employed by the canceller (20) to make the fil-ter (13) stable. It has been found that there is a great deal of flexibility regarding the selection of the delay values. This insensitivity permits designing the delays in ad-vance, and not having to adjust them to different situations as they change, thus no longer requiring a training mode. The canceller (20) dramatically reduces the amount of hardware needed to perform active adaptive noise cancelling, and eliminates the need for the training mode, which in some applications, including automobiles, for example, can be as objectionable as the noise sources that are to be suppressed.

Abstract: A sand screen is positioned in a well adjacent an oil or gas reservoir to be produced. At least one conduit is in juxtaposition with the sand screen and has passageways at selected intervals to establish fluid communications between the conduit and the annulus of the well surrounding the sand screen. A gravel packing slurry is injected down the well to form a gravel pack in the annulus. Actuatable devices associated with the conduit passageways control fluid flow between the conduit and annulus so that if the gravel portion of the slurry forms a bridge in the annulus, thereby blocking slurry flow throb the annulus, the slurry will be diverted from the annulus into the conduit through one or more of the passageways in the conduit above the bridge, downward through the conduit and out through one or more passageways in the conduit into the annulus below the bridge to continue the forming of the gravel pack in the annulus.

Title: Rotatable handle extension for fishing rods and the like
Inventor: LATOUCHE DESMOND J
IPC: A01K87/08
Filed: 1992-03-02
Abstract: ABSTRACT OF THE DISCLOSURE           A rotatable mechanism for reversibly attaching an extension onto the end of a long member is described; in the example a flange extension to go under a fisherperson's forearm and bear the weight of a rod or a net (with or without attached fish) is attached to a rod or net handle.  In one embodiment, splines run on the outside of a shaft affixed previously to the handle, and co-operate with splines on the inside surface of a cylindrical hole in the flange extension.  A screw inserted through the extension and threaded into a hole in the end of the handle prevents longitudinal separation between the handle and extension, and the splines prevent rotational movement.  In cases where the handle needs to be rotated, such as a reel designed to hang down instead of up, the screw is released, the extension disengaged, rotated, reinserted, and the screw is inserted and tightened.  A second embodiment describes a simple screw-on clamp to achieve the same function.  The rotatable handle and extension also permit easy adjustment to comfortably accommodate right- or left-handed fishermen.

Abstract: Abstract of the Disclosure With an infrared radiator, the surface temperature of which is kept constant during measurement, a measuring area on a material surface is thermally irradiated with oblique incidence of the rays. The temperature of the reflected thermal radiation is measured by an infrared thermometer, which is arranged above the measuring area in such a way that the reflected radiation falls into the area of coverage of the infrared thermometer. The entire measuring area of the material surface which lies in the field of coverage of the infrared thermometer must be thermally irradiated. The measured temperature variation of the reflected radiation in dependence on the surface condition of the material is stored in a comparison device.  A set value for the desired surface condition is fed to this comparison device.  The infrared temperature of a material surface, initially unknown with respect to its surface condition, is measured and compared with the stored temperature variation in order to determine the magnitude of the surface parameter. From the value thus obtained and the set value fed in, a differential signal is formed, which is fed via the output of the comparison device to a control  of a treatment device  for the material.

Abstract: A method for varying the color of an image including lines and background. Where the image includes the colors black and white and a plurality of gray pixels, where gray refers to the presence of pixel values between the maximum and minimum pixel values, inclusive, the image is first converted to a color space, such as for example, r, g, b (red-green-blue).Pixel values are thresholded for differentiation between lines and background. When pixels have a value indicating that the pixel is back-ground, that pixel is set to a background color that has been previously selected. Otherwise, that pixel is set to a foreground color. The result is that background is set to a single color, and lines are set to a second color. Alternatively, where intermediate values are present, the foreground color value may be added to the intermediate level color value to produce a gradually varying colored line.
