Title: Optical device for the display of light data collimated to infinity
Inventor: MIGOZZI JEAN-BLAISE
IPC: G02B27/00
Filed: 1990-12-12
Abstract: ABSTRACT OF THE DISCLOSURE    In an optical device for the display of light data collimated to infinity,  an image generator  associated with a  collimation optical  device  gives the  eye  an image collimated  to infinity.  The light  source  that illuminates the image generator  is controlled so  that the position of its illuminating  part is such that  it gives a narrow beam with an image of this  illuminating part centered on the pupil of the eye. This is possible by  means  of   an  oculometer   that  determines   the coordinates of the center of  the pupil of the eye  and delivers a signal enabling an automatic control circuit to adjust the  position of  the illuminating  part of  the source  accordingly.  The  device  can  be  applied  to pilots' helmets for the display of data overlaid on the landscape.

Title: A catheter with a balloon
Inventor: NOGUCHI NORIYASU
IPC: A61F2/958
Filed: 1990-05-09
Abstract: This invention relates to a catheter-cum-balloon characterized in that the balloon is reinforced with composite yarns composed of elastic yarns and non-elastic ones which are each larger than the elastic one in free length. In the catheter-cum-balloon of the present invention, expandability of the balloon is high and thus, when inserted into or pulled out from the blood vessel for the purpose of therapy, the balloon is capable of not only decreasing in diameter without development of creases but also positively expanding to the same size and the same shape at any time. Accordingly, provided are such advantages that: reliability in therapy is increased; an opening incised for therapy, even if small, satisfies the purpose; treatment and care after operation are simple, requiring only a few length of time until cure; and the burden inflicted on the patient and nurse daily is light.

Title: Solar distiller
Inventor: VANDEN BERNARD E
IPC: F24S23/71
Filed: 1991-02-25
Abstract: ABSTRACT OF THE DISCLOSURE         This solar distiller employs a solar collector, preferably a parabolic reflector, and an enclosed distiller vessel having a near-black face to receive concentrated solar rays.  The vessel contains a number of vertical pipes connected to an out-flow pipe at their lower ends.  A supply of water to be purified is maintained in the vessel at a level below the open upper ends of the vertical pipes.  As solar heating of the vessel interior occurs, the water within will begin to boil, evaporate, and form water vapour.  The purified water vapour is urged, under the pressure created within the vessel, to enter the vertical pipes where it is forced into the out-flow pipe for subsequent condensation.  A secondary heat supply is available from secondary water which is heated during condensation of the purified water.

Title: Method and apparatus for image reproduction
Inventor: CARLEBACH EPHRAIM E
IPC: H04N1/405
Filed: 1991-07-26
Abstract: ABSTRACT     Apparatus  and  a technique for generating  a  screened reproduction  of  an image is disclosed. The  technique  includes several steps. The first step involves providing a representation of  an original having input density values of the original.  The second step involves storing information representing a plurality of desired dot configurations, corresponding to various  possible density values. In the third step, for each coordinate pair in  a given  region, containing a multiplicity of coordinate  pairs,  a determination  of whether the given region includes a part  of  a dot  corresponding  to  the input density   of  the  original  is performed.  In the fourth step, for regions which are  determined to  include  a part of a dot, a determination is made  whether  a coordinate pair lies within the boundary coordinates of the  dot.          The  fifth step involves operating the plotter to write  only  if the  coordinate pair lies inside the boundary coordinates of  the dot,  thereby  to  produce the multiplicity  of  screen  dots  of configurations  representing  the  input density  values  of  the original.
