Abstract: ANNULAR ARRAY ULTRASONIC TRANSDUCERS            Abstract of the Disclosure An annular array ultrasonic transducer is provided which comprises a plurality of concentric rings of piezoelectric material having widths chosen for operation at different depths of focus. The total aperture of the transducer is divided into a plurality of contiguous focal depths.  In the near field only the inner element or elements are activated, and rings of increasing radius are added as the depth of focus is increased. The widths of the rings are chosen to keep phase errors across each ring within acceptable limits over the depth of field for which they are energized.  The transition depths at which the aperture is changed are chosen to allow rings of manufacturable widths to be employed while maintaining aperture transitions which prevent banding in the ultrasonic image.

Abstract: ABSTRACT OF THE DISCLOSURE             "A Process for Metal-Enrichment of Lead Bullion"      A process for metal-enrichment of lead bullion, wherein an alkali metal-desired metal intermetallic, such as sodium-antimony intermetallic, is added as a refining dross to the bullion and the desired metal is stripped from the dross and recovered as an enriched bullion.  The process includes the steps of heating the lead bullion, in which the desired metal is to be recovered, to a temperature between 650°F and 900°F; agitating the molten bullion; adding said alkali metal-desired metal intermetallic to said bullion; mixing said intermetallic into said bullion; adding a stripping reagent for stripping said desired metal from said intermetallic; forming a desired metal-enriched lead bullion and a residue dross substantially void of said desired metal; and separating said enriched bullion from said residue dross.  The process may also require a cleansing step to cleanse said enriched lead bullion of any said alkali metal in solution.  Through the control of temperaure, additions of stripping and cleansing reagents and agitation, the process provides economies of materials, energy, time and labor over conventional metal recovery processes.

Abstract: POWER MEASUREMENT IN AN ELECTRICAL DISTRIBUTION SYSTEM HAVING THREE OR MORE WIRES     Abstract A system for measuring power in an electrical distribution circuit having at least three wires includes a Hall-effect generator directly coupled to one of the live wires of the circuit and current transformers coupled to the other live wires of the circuit.  The output of each current transformer is magnetically linked to the Hall-effect generator.  The excitation current for the Hall-effect generator is derived from the line potential between the live wires.  The Hall-effect generator acts to produce an output whose magnitude is directly proportional to the product of the vector sums of the currents flowing in the live wires and the potential between the live wires.  This power indicative output may be accumulated to produce an indication of energy consumed by a load connected to the live wires.  A high frequency A.C. bias is applied to the Hall generator in order to linearize the output of the generator.

Abstract: ABSTRACT Filters are provided at the outputs of data transmission links to overcome attenuation distortion and phase distortion but such filters tend to increase the noise content of received signals. In the present invention a filter coupled to a linear baseband channel is constrained to be an all pass network, thus avoiding any noise enhancement at its output.  The filter is adjusted by means of a channel estimator and an adjustment system to give the channel plus the filter an impulse-response that rises rapidly to its peak, thus simplifying the detection process needed for a satisfactory tolerance to noise.  The required response is obtained by finding those roots (zeros) of the z transform of the sampled impulse-response of the channel, which have a modulus greater than some given value which is not less than unity, and adjusting the said filter such that, in the z transform of the sampled impulse-response of the channel and filter, the said roots are replaced by the complex conjugates of their reciprocals, the remaining roots of the channel z-transform being left unchanged.
