Abstract: CONTROLLED REACTANCE REGULATOR CIRCUIT      ABSTRACT OF THE INVENTION A circuit for providing a regulated a-c or d-c output voltage from an unregulated a-c input voltage.  A series inductance is connected between the regulator input and the regulator output to support the difference in voltage between the unregulated a-c input voltage and the regulated a-c or d-c output voltage.  A controllable shunt reactance is connected to the source of input voltage, through the series inductance, to vary the current through and the voltage across the series inductance.  Control circuitry controls the magnitude of the current which the shunt reactance draws through the line inductance, as required, to establish and maintain the regulated output voltage at the desired output current.

Abstract: FLAT FIELD SCANNING SYSTEM                      ABSTRACT OF THE DISCLOSURE         A flat field scanning system is disclosed which has the following characteristics:  (a) a stationary lens is located between a scanning mirror and a medium; (b) the mirror is moved linearly for scanning; (c) at the start of scan, a beam is directed from or received by the mirror substantially on axis of the lens; (d) the beam distance from the object plane of the lens to the lens and from the lens to the image plane of the lens always increases from the start of scan to the end of scan; and (e) during movement of the mirror, the mirror is pivoted to continue to reflect the beam through or receive the beam from the center of the lens.  Linear movements are utilized in the scanning system eliminating the use of intricate cam surfaces.         In one embodiment, the medium is either a recording medium or a document to be read by scanning and is located at the image plane of the lens.  The scanning mirror is located between the object plane of the lens and the lens and scans the beam to the medium.  A polygon scanner scans a beam onto the medium via the scanning mirror in an "X" direction while the scanning mirror provides scanning of the beam in a "Y" direction.  In a modification of the above embodiment, an oscillating mini-scan mirror is located between the scanning mirror and the object plane and scans the beam to the scanning mirror in the "Y" direction.  The scanning mirror is stationary allowing the mini-scan mirror to "Y" scan only a portion of the medium, which is usually 20-32 "X" scan lines or one text line.  The scanning mirror is moved one text line at a time to allow mini "Y" scanning of the whole medium.         In another embodiment, the medium is a document illuminated by flood lamps and is positioned on the object plane of the lens.          The scanning mirror is located between the image plane of the lens and the lens.  A recording medium is located at the image plane of the lens to receive the image on the document.

Granted: 1979-05-01
Abstract: ABSTRACT OF THE DISCLOSURE      An improved burner for both liquid and gaseous fuels in which the combustion air is divided into at least two parts, comprising primary and secondary air.          The primary air, which is insufficient to completely burn the fuel, creates a flame zone in which there is a deficiency of air, which provides quantities of carbon monoxide and hydrogen.  The combustion products are recirculated, cooled and re-entered into the combustion zone in the region of the fuel and primary air entry, resulting in a reduction in the oxides of nitrogen.  The secondary air, in quantities greater than the primary air, is introduced into a second combustion zone downstream of the first combustion zone.  In the second combustion zone the deficiency in air is made up by the secondary air so that complete combustion can be carried out.  If desired, a third quantity of air can be introduced still farther downstream in the flame zone.

Abstract: ABSTRACT OF THE DISCLOSURE        A particular arrangement of web stiffening members for the extensible and retractable telescoping sections of a crane boom assembly.  A series of web stiffening members are secured to each of the side webs of a telescoping boom section, the web stiffening members being angularly displaced in a particular arrangement on each boom section to provide for reduced stress levels in the section.  The web stiffening members are arranged on each side web in two series of members, the innermost stiffener of each series being reversely positioned about a reference point provided on the boom section.   The reference point for the boom section corresponds to the point of changeover for shear load for the section under cantilever loading.  At the defined reference point of the boom section the innermost stiffener of each series of stiffeners are angularly disposed away from each other to form a V-shaped configuration with the apex of the V directed to the lower or compression flange of each boom section and the remaining stiffeners of each group longitudi-nally spaced outwardly therefrom in respective parallel, spaced relation.  The angular displacement of the stiffeners is derived from a formulation which provides for improved stress levels in the boom section.  The formula set forth below provides, .beta. angle for the web stiffeners when calculated to mimimize the stress level in the web at a given load as follows:       Thus the use of the shear loading diagram for a beam under canti-lever end loading combined with the formulation providing the optimum stiffener angle results in a stiffener arrangement which produces reduced stress levels in the boom section.  The use of Abstract continued..... the method proposed provides two groups of web stiffeners for each side web of each boom section, arranged in parallel longitudinally spaced relation, each group angularly inclined toward the horizontal at the angle prescribed by the formulation, but reversely positioned on opposite sides of the changeover point.

Tracer gas (helium) and pressurizing driving gas (nitrogen), the latter in condensed form, are introduced into the transport vessel when in open condition. The tracer gas is introduced in a plastic bag which occupies a major part of the interior of the transport vessel and through which the tracer gas diffuses at a low rate. The liquid pressurizing gas is introduced in a smaller vessel. After the transport vessel has been sealed, the tracer gas diffuses out of the collapsing plastic bag and the pressurizing gas boils off resulting in a pressuriz-ed tracer gas atmosphere within the transport vessel. The transport vessel is now examined on the out-side with respect to any tracer gas penetrating out through possible leaks in the transport vessel.
