IPC: C12N7/00
Filed: 1987-08-17
Granted: 1990-12-04
Abstract: The invention concerns a method for the culture of the infectious rhinotracheitis virus, TRT/SHS in the turkey that is also responsible for disorders in other bird species such as the infectious big head syndrome (or swollen head syndrome) in the chicken and guinea fowl. According to the invention, samples are taken from sick animals that are inoculated on cell cultures consisting of a continuous line of monkey kidney cells. A large quantity of the virus is obtained. This can be used as an antigen in the production of a vaccine that can be equally used for the immunization of all bird species. The invention also applies to the production of vaccines from viral strains obtained by means of this method.

Abstract: ABSTRACT             An interferometric acoustooptic signal processor utilizing a modified multi-channel Bragg cell comprised of a plurality of sets of acoustic transducers.  Each set of transducers is arranged in a phased array for receiving input microwave signals from respective ones of a plurality of antennae, and applying the received signals to a block of acoustooptic material, resulting in generation of one or more acoustic waves therein.  A laser beam is used to illuminate the Bragg cell and is modulated due to interaction with the acoustic waves, resulting in diffraction of the laser beam and generation of a diffracted beam pattern output from the Bragg cell.  A Fourier transform lens focuses the diffracted laser beam on a back focal plane at a point characterized by two perpendicular coordinates designating the input signal power spectrum and the angle of incidence in relation to the antennae, respectively.  By utilizing a set of transducers arranged in a phased array for each antenna, a large portion of the incident laser power is utilized constructively to increase the total amount of light diffracted, thereby improving signal reception and processing efficiency.

Granted: 1993-07-27
Abstract: ABSTRACT   This invention relates to a shelf apparatus using rollers.  On the shelf frame, horizontally extending roller conveyors are mounted in a plurality of vertically spaced stages. The free rollers of the roller conveyor in each stage are divided into a plurality of groups in the direction of transport.  Driving devices are provided which are operatively connected to and disconnected from the free rollers for each group to forcibly rotate the free rollers.  In two adjacent groups as viewed in the direction of transport, when there is no load at least on the downstream group as viewed in the direction of transport, the free rollers are simultaneously forcibly rotated by the driving devices so that a load is transported from the upstream group to the downstream group.  Thereby, loads are successively fed from the upstream group to the downstream group.  In the most downstream group, the present of a load results in the free rollers assuming the non-rotated state, waiting for the load to be carried out.

Title: Method and apparatus for determining earth station parameters, such as rain margin, with attenuation pads
Inventor: CONANAN VIRGILIO D
IPC: G01R29/08
Filed: 1989-04-18
Granted: 1993-07-06
Abstract: ABSTRACT Methods and apparatus for determining operating parameters, such as rain margin, of an antenna by attenuating the received signal by, for example, the use of calibrated attenuation pads, the method comprising placing such pads in front of the horn of the antenna feed until impulses appear on the screen of a T.V. or monitor connected to the antenna.  The antenna alignment is peaked by determining the orientation of the antenna that yields the minimum impulses.  The rain or impulse noise margin is determined by summing the attenuation factors of the pads with the increase in delta G/T due to the attenuation.  The tuning of the receiver can be checked by observing the number of black and white impulses.  The positioning of the antenna with respect to the polarization of the signal can be checked by determining the rotational position of the feedhorn which yields the minimum number of impulses.  The descrambler dropout margin and clear sky carrier-to-noise ratio are determined by the addition of proper constants.  The antenna can be a Ku-band antenna.  A set of pads related, for example, by powers of two, for use in determining operational parameters of an antenna is also disclosed.  By use of these methods and apparatus, the antenna system's conformance with specification requirements can be determined.
