摘要： Method and composition for the diagnosis of equine infectious anemia virus infection in animals involving the use of an immunodiffusion reaction plate, wherein separate wells in the reaction plate contains an antigen associated with the virus, an antiserum to the virus and the serum of the suspect animal. A positive response is indicated by a precipitin line of identity between the antigen well, antiserum well and the suspect serum well. Also disclosed is a novel antigen composition and a method for obtaining the same which is particularly suited in a diagnostic test for equine infectious anemia in animals.

摘要： Multi-axis resonant cavities are provided in which a microwave semiconductor oscillator, e.g., an L.S.A. diode, operates in a below cut off mode with respect to the propagation characteristics of the cavity. An output coaxial transmission line extending into the cavity is radially spaced from the semiconductor and couples energy to a load by means of mutual inductance. In one arrangement, a flat circular cavity is formed in a block of electrically conductive material with a microwave semiconductor coaxially mounted at the center of the cavity having one face in electrical contact with a wave trap through which DC bias voltage is applied. The transmission line is offcenter, adjacent to the semiconductor. In a modification of this arrangement, the floor of the circular cavity forms a truncated cone and the side wall comprises a spherical section. The angle of the conical floor is used to determine the cavity inductance. A flat elliptical cavity is described in one arrangement wherein the semiconductor and the transmission line are located respectively at the two foci of the ellipse. The elliptical cavity forms a resonator as well as means of coupling out energy. Other arrangements of the circular cavity are described in which a plurality of semiconductors are located symmetrically in the cavity. In another system a semiconductor is located at the center of the partial circular cavity connected to a ridge wave guide having a coaxial transmission line displaced from the semiconductor extending through the ridge. A special low impedance slug in the output line of a multi-axis cavity is designed to load the fundamental frequency of oscillation of the diode and reduce the loading at the second harmonic, thereby producing more power at the fundamental frequency. Varactortuned Gunn oscillator and Gunn effect amplifier embodiments are also presented.

摘要： Disclosed is an improved process for the preparation of a new heteropolysaccharide by a fermentation process comprising culturing a heteropolysaccharide-producing strain of a microorganism of the genus Methylomonas on an aqueous culture medium containing methanol as the sole source of assimilable carbon. The concentration of the product polysaccharide in the fermentation broth is increased, the fermentation time is shortened, and the properties of the polysaccharide are improved by the controlled addition of methanol to the fermentation process near the end of the logarithmic phase of growth of the bacteria.
