Abstract: ABSTRACT OF THE DISCLOSURE A steerable null antenna processor system is described for receiving desired wave energy signals from at least one angular region of space, and for suppressing interfering signals from at least one other angular region. The system includes at least first and second antenna elements.  Nulling means are coupled between the antenna elements and a common port to supply signals to said common port, and have phase means and amplitude means, both adjustable in incremental steps.  The nulling means also has control inputs, responsive to control signals to adjust respectively the phase and amplitude values of the nulling means.  The amplitude means is a variable ratio combiner having a quadrature hybrid, a sum-difference hybrid, and two adjustable delay lines between said hybrids.  A digital controller means is also included having clock means, sample storage means, comparison means, feedback input means, and phase and amplitude memory means having connections to control inputs of the phase and amplitude means respectively.  Apparatus between the common port and the feedback input means supplies feedback signals containing a representation of the interfering signal at the common port.  Clock signals provide successive cycles.  The comparison means operates during each cycle to compare a feedback signal from the feedback input means to a previous sample thereof stored in said sample storage means, to indicate improvement.  It also supplies the control signals via the memory means to the nulling means to make adjustments  for steering at least one null to the interfering signals. Preferably the nulling means is operable selectively for one of receiving and transmitting, and the phase and amplitude means are up-down counters, in which values are more preferably stored as binary numbers.  Still more preferably, second nulling means are provided coupled to third and fourth antenna elements.

Abstract: TITLE Polyurethane molding process with siloxane internal release agent.                           ABSTRACT An improved polyurethane RIM process using a polycarboxy-functional alkyl siloxane as an internal release agent characterized by:      (1)  Tool break-in or preconditioning with siloxane treatment of the surfaces; (2)  Supplying the siloxane to the mix head as a third stream when necessary to prevent undesired side reactions; (3)  using a minimal amount of siloxane that is inadequate for mold release in the absence of the tool preconditioning; (4)  Adjustment of catalyst package to counter the inhibiting effects of the siloxane. The use of a bare minimal amount of siloxane prevents excess siloxane from  appearing in the surface of the article and causing subsequent paint wet-out and like difficulties.   The third stream isolating of the siloxane prevents its carboxy-functional groups from reacting with the prepolymer or with other ingredients that may be carried in the polyol blend.

Abstract: ABSTRACT     A combustible gas producer plant is described in which a finely divided inert particulate material fluidised bed is divided into a first, combustible-gas producing section and a second, heating section, to both of which sections fuel is fed.  Heat transfer, by bed material migration, from the second to the first section sustains the reaction in the first section leading to the production of combustible gas.  A diaphragm water wall divides and surrounds the volumes above bed sections and is part of a boiler generating steam used (optionally with added oxygen) to fluidise the first bed section.  The steam is also used to fluidise the bed material at the boundary of the bed sections and prevent in-bed gas migration across that boundary.  The second section of the bed is fluidised with air or an air/inert gas mixture.  Fluidisation is effected with sparge tubes and the plant may include evaporator, superheater and economiser sections for the boiler.

Abstract: FAULT INDICATOR WITH BIDIRECTIONAL INDICATOR WINDING     Edmund O. Schweitzer, Jr.     Abstract of the Disclosure A fault indicator for indicating the occurrence of a fault current in a power distribution system includes a test-point-mounted circuit module and a remotely-mounted indi-cator module.  The indicator module incorporates a bidirectional magnetic winding and a magnetic indicating element having a magnetic state conditioned by energization of the winding.          Upon the occurrence of a fault in the power system trip cir-cuitry within the circuit module energizes the winding with current in one direction to condition the indicator element to a fault-indicating magnetic state.  Upon restoration of current in the system, reset circuitry within the circuit module energizes the winding with current in the opposite direction to condition the indicator to a reset-indicating magnetic state.  The use of currents of opposite direction in a single magnetic winding provides greater flux density at the indicating element, and enables the indicator module to be connected to the circuit module by means of a two conductor cable.  Alternate embodiments of the invention, utilizing visual-type indicator modules and current-reset modules, are also shown.

Abstract: Abstract of the Disclosure A DC coupled signal translating circuit for supplying auxiliary graphics information switching signals to a video signal processor. The switching signal comprises plural switching levels including a quiescent level. The translating circuit includes first and second complementary conductivity input transistors with interconnected emitter signal inputs for receiving switching currents representa-tive of the graphics switching signals via a conductor which undesirably exhibits a parasitic capacitance. The transistors are biased to conduct a nominal quiescent current and develop collector output currents which are proportional to the input switching currents, and which are respectively coupled via current repeating networks to control inputs of the video processor. Switching delays attributable to the parasitic capacitances of the input coupling conductor are significantly reduced due to the emitter voltage clamping action of the input transistors for all conditions of the input switching signals.
