Abstract: In one half portion of one surface 11a of a substrate 11 there are formed in parallel V grooves 14 1 and 14 2 of the same depth, in which optical fibers 21 and 22 are disposed and positioned with their axes held at a height H1 with respect to the surface 11a. The optical fibers 21 and 22 have lens portions 21 a and 22a formed integrally therewith at one end, and the end faces of the lens portions 21 a and 22a are tilted at an angle .theta.' from their axes. A beam sputter 31 is mounted on the substrate 11 on a center line 25 between elongations of the optical fibers 21 and 22, and light emitted from the lens portion 21 a propagates through space and is launched in focused form into the beam sputter 31, and a portion of the incident light is reflected, which propagates space and is launched in focused form into the lens portion 22a and propagates through the optical fiber 22. The light having passed through the beam splitter 31 is launched into a light receiving element 32. By monitoring an electrical signal that is output from the light receiving element 32, it is possible to monitor the light propagating through the optical fiber 22.

Abstract: An apparatus is provided for removing and transporting articles, such as contact lens sections from a manufacturing line to inspection and packaging stations. The lenses are deposited in a transparent plastic primary package which carries the lenses through the inspection station and becomes part of the primary package when a cover is sealed thereto. The invention includes various assemblies, including lens transfer assemblies, deionized water filling and removal assemblies, a water degassing assembly, a lens inspection assembly, and a lens package sealing assembly. The lenses are removed from pallets at a post hydration station, transported and spatially redistributed, and deposited in the primary packages disposed on a second set of pallets. The packages on the second set of pallets are filled with degassed deionized water. The contact lenses and packages are then transported to an inspection station. After inspection, the lenses and packages are transported to a water removal assembly, and then to another transfer assembly. This transfer assembly separates those lenses which passed inspection from those which did not, and places those that did in a consolidating assembly. The lenses and packages are then filled with saline solution and a foil label is then sealed thereto to form the primary package.

Abstract: An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

Abstract: The invention relates to a method for producing denture parts or for tooth restoration. According to said method, to reconstruct a tooth requiring repair or a defective condition, at least some of the missing exterior surfaces of denture parts or tooth restorations are adapted to the existing residual tooth material and/or the opposing teeth and/or the position of the neighbouring tooth and/or the occlusion position, by means of the optimisation of a generic dental-model data record of the desired tooth type, thus varying the linear factors of at least the most important components, (determined from the electronic data records of a larger number of measured tooth surfaces by primary axis analysis methods), in such a way that the selected optimisation criteria are fulfilled by the minimisation of an error function. After the successful adaptation of said surfaces to the residual occlusion position and the completion of the data record, the reconstructed denture part or the reconstructed tooth restoration is machine-manufactured.

Abstract: An improved or alternative method for manufacturing resin-impregnated endless belt structure and improved or alternative belt structure for extracting water from a web of material, designed for use on a papermaking machine are disclosed. The method requires the application of a polymeric resin material onto a base substrate in a controlled manner so as to control the x, y, z dimensions of the material deposisted to create a precise predetermined pattern in deposits, each of which has a plurality of droplets of material.  The droplet has an average diameter of 10µ. (10 microns) or more. The polymeric resin material is then set by means appropriate to its composition, and, optionally, may be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.  The present method and belt, at least, eliminates the necessity for a separate step(s) to produce grooves or voids required previously.
