Filed: 1987-04-15
Granted: 1992-09-01
Abstract: ABSTRACT OF THE DISCLOSURE        A glide shoe arrangement for a variable crown roll is disclosed. The roll comprises a fixed central axle on which a hollow cylindrical roll mantle is rotatably journalled.  A series of piston-glide shoe arrangements are fitted along the length of the roll between the axle and the inner surface of the roll mantle and are adapted to be loaded by hydraulic pressure fluid so that each piston loads a corresponding glide shoe against the inner surface of the roll mantle to control the distribution of nip pressure in a nip formed by the variable crown roll and a counter roll.  The piston-glide shoe arrangements are fitted in cylinder bores formed in the axle.  spherical surface bearings are fitted between the loading pistons and the glide shoes, the center of curvature or rotation of the bearing surfaces being located on the side of the slide shoe.  A pin-shaped projection is fitted in the loading piston and extends through the spherical bearing.  A sealing articulation arrangement is situated between the pin-shaped projection and either the glide shoe or a projection part attached to the glide shoe.  The pressure fluid is passed through ducts from the loading space of the cylinder bore through the pin-shaped projection and into hydrostatic lubrication spaces on the glide shoe.

Title: Varicella-zoster virus as a live recombinant vaccine
Inventor: ELLIS RONALD W
IPC: A61K39/295
Filed: 1987-06-16
Granted: 1995-11-21
Abstract: A vaccine strain of varicella-zoster virus (VZV), tested in clinical trials, is capable of preventing chickenpox in children.  This virus has been modified by the introduction into its genome of heterologous DNA which encodes an immunogenic polypeptide of another human pathogen.  This heterologous polypeptide is expressed in cells infected by the recombinant virus.  Such recombinant VZV is useful as a vaccine for chickenpox as well as for heterologous pathogens.

Filed: 1987-08-07
Granted: 1992-05-12
Abstract: Abstract of the Disclosure An optical transmission system wherein light is transmitted  from a transmitter to a receiver by at least  one  transmission  optical  fiber.   The  system includes a dispersion transformer which receives light from  one  of  the  components,  compensates  for  or transforms  the  delay  distortion  of  the  various wavelengths  transmitted  through  the  system,   and provides  the  next  component  in  the  system  with  a compensated or transformed light beam.  The dispersion transformer comprises means for receiving light from one of the  components  and dispersing/separating  the light into a plurality of spatially separated beams which are directed onto the endface of a multimode optical fiber.  The position of each beam on that end-face is a function of the velocity with which the light that forms the beam propagates through the transmission optical fiber.  The multimode fiber is characterized in that  it  comprises  a  plurality  of  light-conducting channels,  adjacent  ones  of  which  are  separated  by cladding regions having refractive indices lower than those of the adjacent light-conducting channels.

Abstract: IMPROVED HYDRAULIC VALVE ASSEMBLY                       ABSTRACT An improved hydraulic valve assembly comprising a directional valve, such as a spool valve, and a pilot valve of a unique design.  The pilot valve comprises a rocker arm, which is controlled by motor means imparting a torque on the rocker arm so as to move a pair of flappers toward and away from associated nozzles controlling pilot pressure to opposite ends of the directional valve. When one of a pair of transducers senses the pressure of hydraulic fluid returning from the directional valve, an opposing torque is imparted to the rocker arm.  Equilibrium is achieved when the torques balance each other.  The nozzles are provided with annular buffers preventing the nozzles and the flappers from being pressed against each other.  The directional valve employs flow restrictors of a unique design wherein annular plates, in a stack, are provided with integral, arcuate, spaced baffles.  The baffles, which are equal in angular width, are interdigited so as to provide serpentine paths for hydraulic fluid flowing radially through such restrictors.

Abstract: ELECTROSTATIC DEEP HEATING APPLICATOR              ABSTRACT     An electrostatic deep heating applicator deposits RF energy in a relatively uniform manner throughout a given cross-section of the human torso, thus resulting in  a  similar  uniform  heating  of  the  region.    The applicator uses a pair of identical, rectangular (70), flat  (82) or cylindrical applicators which generate a heat-producing electric field predominantly parallel to the major axis of the body  (74)  so as to minimize excessive  surface  heating.    The  applicator  finds particular use in the treatment of deep seated cancers in patients.  It need only be placed near the torso for satisfactory operation, thus allowing a relatively large air gap between it and the patient.   It requires very minimum set-up time, is convenient to use and is non-threatening to the patient.
