Title: Method and means for coating the interior of a  vertically disposed elongate hollow member
Inventor: CLAYTON DONALD W
IPC: B05D7/22
Filed: 1979-01-31
Granted: 1982-08-03
Abstract: ABSTRACT OF THE INVENTION          The method involves injecting into the hollow member adjacent its upper end a body of the material for coating the interior of the member, and then forcing the body of coating material downwardly while forcing an annular portion of the material laterally outwardly into engagement with the walls of the hollow member. This is done by a brush having bristles facing outwardly and of sufficient flexibility to enable them to pass through a stricture of predetermined degree in the hollow member and to expand when not in such strictures so that at all times the bristles are in close proximity to the inner surface of the hollow member and spread the coating material therealong, pushing the extra coating material ahead to subsequently coat lower portions of the interior of the hollow member. Part of the coating material will escape past the brush to the space thereabove, and when the brush reaches the  lower extremity of the hollow member it will be retracted to coat the interior of the hollow member a second time upon upward movement of the brush to the upper end to the hollow member.  The means for coating include a brush assembly made up of one or more brushes sized and constructed as above stated, disposed singly or one above the other in multiple, and having a weight connected thereto above or below the brush or brushes, of sufficient density and small enough cross section so that the brush assembly as a whole will move downwardly through the hollow member at a rate greater than would the material for coating the hollow member under the force of gravity alone.  Means is provided for retracting the brush assembly after the downward coating trip

Inventor: SLAGMOLEN HERMAN C
IPC: C01C1/10
Filed: 1979-04-10
Granted: 1982-09-07
Abstract: "Method for the removal of ammonia and ammonium salts from industrial waste water ABSTRACT OF THE DISCLOSURE     A method for removal of ammonia and ammonium salts from industrial waste water comprises the steps of passing the water through distillation columns in countercurrent to steam or preheated air, and at an intermediate stage adding alkali (e.g. milk of lime) in order to convert ammonium ions to ammonia.  The distillation column before the addition of the alkali is a fresh supply of steam or preheated air, different from that of the distillation column after the addition of alkali.          The distillation before the alkali addition is such as to remove substantially all carbonic acid, in order to reduce the amount of alkali required and to avoid the formation of scale.

Abstract: MOWING ROTOR                      Abstract A flail-type mowing rotor, spinning about a horizontal axis transverse to its path of travel, has specially configured, swingable cutters that provide finish-cut quality notwithstanding design features that minimize the number of cutters required on the rotor, allow them to be fabricated from stamped, relatively light-gauge metal, and promote quick and easy removal and replacement of cutters as may be necessary or desirable.  Each of the cutters comprises a pair of back-to-back, generally L-shaped blades having a medially dis-posed, obliquely oriented offsetting portion that locates the transverse cutting edge in offset relationship to the plane of the flat mounting portion of the blade.  Thus, when the blades are disposed back-to-back on the rotor, the transverse cutting edge formed by the two cooperating blades is interrupted at its midpoint to present a gap through which uncut grass may pass as the rotor spins, thereby wiping the cutter clean and eliminating grass wrap.  arranging the cutters in a helical series about and along the hub of the rotor causes the cutting edge of one cutter in the series to overlap the gap of the next adjacent cutter in the series, thereby assuring a complete cut.  Formed contours on each blade provide a bottom cutting and bottom sharpening design as well as induce a grass-lifting airflow tending to encourage the grass to stand upright for complete severance, and the mounting hardware for the cutters is such that the back-to-back relationship of the blades of each cutter is maintained without sacrificing the ability of the cutters to yield instantaneously in a retrograde swinging motion upon striking solid obstructions.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of monitoring structural and mechanical properties of drilling mud and a device for realizing this method includes the determination of the viscosity of drilling mud via a viscosimeter and the determination of the shear strength of the mud via a shear strength measuring instrument, both of which have driven sensitive elements immersed in the drilling mud.  The signals of the sensitive elements are con-verted by converters indications of the parameters being measured and are compared.  The sensitive elements are connected to the same pole of a power source.  An electrode immersed in the dril-ling  mud is connected to the opposite pole of the power source. The current flowing between the electrode and the sensitive elements is measured and, when the current is stabilized, the con-verters produce signals porportional to the viscosity and shear strength of the drilling mud.  A first ratio of the shear strength and viscosity signals is determined, the signals being produced by a divider connected to the outputs of the converters.  Then, the polarity of the power source is reversed and a second ratio of the shear strength and viscosity signals is determined.  The arithmetical mean of the first and second ratios is then determined.

Abstract: ABSTRACT              FILTERING METHOD AND APPARATUS THEREFOR      A method of and apparatus for removing particulate contaminants from a gaseous stream.  Broadly, the apparatus comprises a housing containing a substantially vertical granular material retention member having upstream and downstream faces, a substantially vertical microporous gas filter element, said member and element being spaced apart to provide a zone for the passage of granular material therethrough.  The housing further comprises a gas inlet means, a gas outlet means and means for moving a body of granular material through said zone.  In operation, a gaseous stream containing particulate contaminants passes through the gas inlet means and upstream face of the granular material retention member, passing through said member, said body of granular material, the microporous gas filter element and then out the gas outlet means.  The particulates carried in the gaseous stream pass into the granular material and are retained in the body of granular material and upon the upstream face of the gas filter element.  The body of granular material is moved through the zone and across the upstream face of the gas filter element to scour the upstream face and remove the collected particulates, which are carried out of the housing, such that a substantially uniform pressure drop across the apparatus is maintainable during its operation.

Abstract: Abstract The disclosure describes an arrangement to measure precisely probe-to-model board distance in a simulator. A source of radiation is positioned to emit a beam toward a model board surface on which a scaled terrain model is constructed.  A fixed position lens collects reflected radiation and directs it onto a sensor device which develops an electrical signal indicative of displacement of the reflected beam, which, in turn, varies directly as the distance between the probe and the model board surface.  One embodiment describes an arrangement in accordance with the Scheimpflug condition whereby focus is maintained without concern for the depth of field as the probe approaches and withdraws from the surface of the model board.

Abstract: ABSTRACT OF THE DISCLOSURE      A flexible and versatile high performance input/output (I/O) controller for transferring data between a host processor and one or more I/O units. One feature for improving performance is the provision of an interleaving mechanism for inter-leaving two different modes of data transfer between the host processor and the I/O controller.  One mode is the cycle stealing of data between the I/O controller and the main storage unit of the host processor with such cycle stealing being controlled by the I/O controller.  The other mode is an I/O command type of data transfer mode which is under the control of the host processor and wherein for each word of data transferred the host processor supplies an I/O command and an I/O address to the I/O controller.
