Planar active endfire radiating elements and coplanar waveguide filters with wide electronic tuning bandwidth
(United States. Patent and Trademark Office, 1992-08-25)
Microwave and millmeter-wave system components are fabricated by using slotlines extending from the periphery of CPW resonators. This technique permits the degree of electrical coupling between the CPW and and the slotlines ...
Methods for producing superoxide ion in situ
(United States. Patent and Trademark Office, 1992-09-01)
Three methods are provided for generating superoxide ions in an aprotic solvent. In each method a compound that is dependent on the particular reaction mechanism of the method reacts with dioxygen dissolved in the aprotic ...
Treatment of bacterial infection with oral interferon-α
(United States. Patent and Trademark Office, 1998-10-06)
Bacterial infections are treated by the administration of alpha-interferon at a dosage of from about 0.1 to about 5 IU/lb./day such that the interferon is held in contact with the patient's oral and pharyngeal mucosae. The ...
