Abstract: ABSTRACT OF THE DISCLOSURE Polyhedral structures which are, for example, self supporting domed buildings having a plurality of faces arranged in a symmetric pattern, and in a preferred embodiment, the gridwork structure is defined by sixty identical equilateral triangular faces; having two parallel hexagonal sides of six triangles each that are bounded by six side sections each consisting of eight triangles forming a pair of pentagonal pyramids, that have two triangu-iar faces in common. This equilateral faced gridwork is expandable without bound to form larger polyhedra domed buildings by systematically adding groups of additional face structures. Numerous series of Face edges con-necting end to end, circumscribe the polyhedra domed building to serve as truncations to form juncture walls or a base on which the dome portions of the structure can be supported.

Abstract: PULSE GENERATOR                Abstract of the Disclosure A read head for a Wiegand type wire.  The read head establishes an asymmetric field to which the wire is subjected. A setting magnet at a first position establishes a sufficiently strong positive field to set the core and shell of the Wiegand wire in a first confluent state.  At a second position, the field is sufficiently negative so as to assure that the core switches state thereby establishing a reverse state for the wire.  The field does not go strongly negative and thus the state of the shell is not reversed.  At a third position, the field becomes sufficiently positive so as to cause the core to reverse its state again thereby switching the wire from its reverse state to its confluent state.  This particular switching occurs in close proximity to the pickup coil thereby providing an output pulse in response to the switch of state of the wire from reverse state to confluent state.                                  -i-

Abstract: LARGE CAPACITY AIR-POWERED SMOKELESS FLARE            ABSTRACT OF THE DISCLOSURE    A large capacity air-powered flare for smokeless combustion of very large volumes of vented waste gases, comprises a first inner vertical conduit of diameter D1, for the flow of waste gas, and a second larger coaxial conduit of diameter D2, for the flow of primary com-bustion air, at a selected velocity in the annular space therebetween.  Above the top the inner conduit there is a cylindrical obstruction of diameter D3 which is greater than D1, but less than D2.  This forces the upwardly flowing gases to be deflected outwardly and upwardly into the second annular space between the obstruction and the outer conduit. The velocity of primary combustion air in the second annular space is at least 50 f.p.s., which serves to thoroughly mix with the inflowing gases so that as they rise through the second annular space they continue flowing above the top of the flare as an annular wall of high velocity gas, air and flame.  This high velocity annular flow has large surface area on the outside and inside.  Because of the high velocity of flow, secondary air is induced  into the outside wall of this column, and also axially downwardly into the interior of this flow, where it moves radially outwardly to intersect the flowing gas and provide  additional combustion air.

Abstract: Abstract:    A model of an industrial plant is constructed with a mathematical procedure known as the Kalman filter.  The presumed value or predictive value of a certain parameter of a plant is compared with the actually-measured value of the parameter, and the state transition matrix and drive matrix of the Kalman filter are corrected.  When it is difficult actually to measure a parameter that is a direct controlled object, the model is corrected by utilizing another parameter whose actual measurement value is easily obtained.  When the plant has a feedback control system based on the proportional-plus-integral control, the gain of the system is corrected in correspondence with the corrections of the elements of the matrices.
