Granted: 1982-04-13
Abstract: Abstract of the Disclosure A support is disclosed for a spherical tank comprising a foundation operatively associated with an outer boundary ring and with a layer of sand bearing the tank.  In order to avoid problems associated with storage of media whose temperature is below that of the tank surroundings with the resulting lifting of the tank by a bead of ice, the disclosed invention provides a filling of insulating concrete between the foundation slab and the sand layer inside the boundary ring.          The top of the filling defines a support surface for a layer of sand whose shape corresponds to that of the spherical exterior of the tank.  The invention achieves the above object while providing a relatively inexpensive support for the tank.

Abstract: AN ADAPTIVE INTERFERENCE SUPPRESSION ARRANGEMENT          Abstract The present invention relates to an adaptive interference suppression arrangement.  In the present arrangement, a main antenna picks up the desired signal and some interfering signal and a small auxiliary antenna is pointed in the direction of the interfering source and picks up a sample of the interfering signal. The interfering sample is then put through a quadrature modulator for adjustment of its phase and amplitude to provide an estimated cancellation signal at the output. This estimated cancellation signal is then combined with the main antenna output to give a corrected signal.  After down-converting, the present system detects the power in the corrected signal and a processor, in response to such power detection, generates a small dither signal which is added to the control signals to vary the phase and amplitude in the quadrature modulator of the residual interference in the corrected signal.

The method also includes the steps of inserting the closed end of the compo-site billet into a close-fitting bore of a die having within the bore an extrusion orifice of a diameter less than that of the bore, inserting a plung-er into the bore of the die against the filled end of the composite billet, and applying pressure to the plunger to force all of the composite billet except a terminal portion adjacent to the filled end thereof through the ex-trusion orifice to form an electrode blank having the unextruded terminal portion as an upper headed portion and a rod of reduced diameter extending longitudinally therefrom as a lower portion of a diameter equal to that of the extrusion orifice and a length greater than that of the composite billet. The cylindrical billet of corrosion-resistant metal can be nickel or nickel alloy and can be formed into the cup by back-extrusion.  The cylindrical billet of metal of high thermal conductivity can be copper, and, after being inserted into the cup, can be compressed therein to force a lower end and the cylindrical walls thereof into close-fitting relationship with the cavity of the cup.
