Abstract: ABSTRACT OF THE DISCLOSURE       According to the present invention, a new suspended ceiling system is possible of the type having a plurality of removable panels which are supported below a grid network.          The grid network comprises structural elements interconnected by junction members with the cells of the grid network sized to receive a panel about the periphery thereof.  These structural members cooperate with framed panel members to accurately align adjacent panels and position them at a certain height below the grid network.          Access to the area above the panels is easily obtained by removal of any of the panel members.  Each panel is urged into abutting contact with the grid network to provide a seal therewith such that the area above the ceiling may be used as a return air plenum.  The particular frame member for the panels facilitates mechanical connection about and to the body member of the panel and also simplifies removal of the panel.

Abstract: The invention refers to a system for data display by means of magnetically controlled bistable rotors. It is characterized by the fact that this point is itself comprised of several colored ranges which are juxtaposed and borne by distinct rotors (101, 102, 103, 104) grouped to be controlled synchronously and by the fact that, so that all the rotors of the same group are activated at the same time, this system includes a single electromagnet (10) the poles (17, 18) of which are placed in the plane of the axes of the rotors on either side of this group of rotors so as to directly exert their effect only on the permanent magnets (6) of the rotors (101, 102, 103, 104) located at the ends of the group, and this exclusively on their pole oriented towards the outside of the group. Application to display of data which must be read at great distances.

Abstract: OPTICAL TIMING AND ANALOG-TO-DIGITAL CONVERSION    METHOD AND APPARATUS          ABSTRACT OF THE DISCLOSURE           An optical timing and A/D conversion method and apparatus for converting analog signals obtained by movement of a plurality of reaction vessels relative to one or more beams of light from analog to digital signals.  The sample signals are obtained each time a reaction vessel passes through a beam of light.  The converted digital signals indicate the absorbance of the respective vessels and their contents.  Each of the reaction vessels or cuvettes has translucent wall portions providing a radiation path there-through for the light beams which may be monitored by photo-meter means in a chemical reaction analyzer.  The vessels are repeatedly passed through the light beams of the photometer means as chemical reactions take place therein, the purpose being to monitor the changes in the reaction of the fluids therein by measuring the changes in the absorbance of the vessel and fluids.  The sample interval of the analog signal is repeatable for each vessel for each light beam and              may be shifted to select the best portion of the analog signal generated as the vessel passes through the particular light beam.  The A/D conversion also may eliminate the dark sample or noise error between the light beams and the reaction vessels and may eliminate the variations in the sample signals caused by changes in the rate of relative movement between the beams and vessels and changes in the velocity of the rotating beam.

Abstract: 16                  49,113 ABSTRACT OF THE DISCLOSURE This invention provides for mounting a single-crystal doped boule of silicon in a float zone apparatus. A vacuum or other ambient is established within the appar-atus and an rf coil is passed along the boule's length. The rf power is such that the boule is melted to depth "d" which  is  less  than the diameter of the boule.  Dopant within the molten depth "d",  diffuses to the surface of the melt  and evaporates,  thereby leaving upon resolid-ification  a  relatively high  resistivity  single  crystal sheath along the length of the boule.  Wafers cut from the boule can be used for making semiconductor devices with a high resistivity edge portion, thereby providing a device with a high breakdown voltage without the need for field rings, beveling or coating.

Granted: 1983-07-26
Abstract: Abstract A method of forming artificial fingernails includes the steps of forming a negative impression mold of a human finger, and then making an artificial plaster finger from that impression mold.  Once the plaster finger has cured, a layer of tape which has been cut and shaped to the desired length and contour is applied to the outer end of the nail portion of that plaster finger.  Thereafter, another negative impression is made and another artificial finger also of plaster is created.  This second plaster finger is identical to the first with the addition of a plaster portion representing the artificial nail.  This plaster finger is then coated with a lacquer to seal the plaster and a heavy layer of lacquer is placed over the nail portion after any unevenness has been smoothed out.  Once the plaster finger is finished, the nail portion and surrounding top portion of the finger is covered with a layer of silicone rubber. After this layer cures, it is placed in a backing mold member which is filled with wet plaster.  When the plaster sets, a silicone rubber master mold results.  Artificial fingernail material is then placed in the mold and the mold is pressed onto the corresponding finger.
