Abstract: Un jeu d'adresse et de  stratégie qui peut se jouer  sur presque toutes  les surfaces (gazon, sable, eau, ciment, etc.) et qui peut se jouer aussi bien à l'intérieur qu'à l'extérieur de  la maison.          Ce jeu  présente certaines  similitudes avec le  "tic-tac-toe". Le jeu comprend un cadre réceptif muni de  neuf carreaux et de quatre groupes de disques dont deux groupes pour chacun des joueurs.  Les carreaux  représentent  les  cibles  à atteindre  et  les  disques représentent  les projectiles.  Un premier  groupe de projectiles possède au  moins  neuf  disques  de  même  diamètre,  densité et épaisseur.  Un second  groupe comprend  trois disques  de diamètre sensiblement  plus grand que celui du premier groupe. En raison de leur diamètre plus grand  relativement à l'ouverture des carreaux, ces seconds  disques ajoutent  au degré de difficulté d'atteindre les cibles. En contrepartie à cette difficulté accrue, les disques de  grand  diamètre  ont le  pouvoir  de  déloger  les disques  du compétiteur  et de  prendre possession  d'un carreau.  Les joueurs jouent à tour de  rôle en utilisant  d'abord les disques de  petit diamètre, plus  facile à loger  dans les  carreaux, pour  ensuite utiliser, de façon stratégique, les disques de grand diamètre pour déloger ceux du compétiteur.

Title: Zero loss waveguide coupler
Inventor: FINK DAVID
IPC: H01S3/08
Filed: 1993-04-19
Abstract: A waveguide coupler comprises a curved end reflector mirror that images a waveguide exit back into the waveguide with an essentially exact reproduction of the waveguide output intensity distribution.  The coupler also comprises a lens disposed near the waveguide exit at a point between the exit and the mirror, the lens providing a phase compensation to the beam passing therethrough such that the phase of the beam returned to the waveguide matches that of the exiting beam.  Thus, coupling losses due to clipping of the returned beam at the exit/entrance to the waveguide bore and coupling losses due to a mismatch of the returning field phase to that of the waveguide mode are made essentially zero. Other embodiments of the coupler are presented wherein the phase compensating lens is positioned at locations other than adjacent to the waveguide exit, or wherein no inversion of the imaged field field distribution occurs, or wherein the beam is not caused to be focused at the center of a lens, or wherein one waveguide is coupled to another waveguide having a similar sized or a dissimilar sized bore.

Title: Production of bacillus entomotoxins in methylotrophic yeast
Inventor: PREVATT WILLIAM D
IPC: A01N63/50
Filed: 1993-07-29
Abstract: ABSTRACT       The present invention relates to a novel microbiological process for producing insecticidal toxins using recombinant DNA technology and more particularly to the production in methylotrophic yeast cells, especially those of the species Pichia pastoris, of larvicidal toxin polypeptides which are indigenous to entomocidal Bacillus spec    and strains.  This novel and efficient method produces large quantities of biologically active Bacillus entomotoxin compositions, by culturing cells of a species of methylotrophic yeast which harbor a heterologous gene for expressing a Bacillus entomotoxin polypeptide under conditions such that the heterologous gene ifs transcribed int he cells. The methyloptrophic yeast cells are an attractive food and are readily ingested by susceptible insect larvae, such that the entomotixin polypeptide may be efficiently delivered to the gut of the target insect where it takes effect.

Title: Odmogh - device for the overall diameter measurement of groups of hair or fibers
Inventor: NISSIMOV JOSEPH N
IPC: A61B5/103
Filed: 1993-12-29
Abstract: A device which measures the overall diameter of groups of hairs or fibers and reduces the work required to obtain their statistical parameters. In the preferred embodiment an outer hollow cylinder is mounted between the measuring surfaces of a micrometer. An inner edge of a trough made in the cylinder articulates with an edge of a half cylindrical portion of a piston moving within it by means of a handle; the two parts thereby making a window with diametrically opposed halves. A spring presses the piston edge to the trough edge by sliding the piston on slopes against two parts with short steps and a block disengages one end of the piston to let hair in when open. An elongated step with a railing is placed under the piston half cylinder thus making the window into a face of a hollow triangular prism. The railing rises higher than the edge of the trough so that when the piston and trough edges nearly meet the elongated bottom step must turn and bend the hairs. Closing the window in one dimension therefore lays the hair single file and on their major ellipsoidal axis. In the second dimension the hairs slide with minimal friction due to their edge contacts within the device. When the fibers begin to compress one another they tilt characteristically and their total thickness can be read by the micrometer. A hair stop placed under the functional corner of the trough maintains the hair perpendicularly oriented in the window.
