[Crouch, Earl Thomas] 1 River Road, Schenectady New York 12305, US A method for providing an abrasion-resistant, radiation-cured coating on a surface of a polymeric substrate is disclosed, as well as the article produced from the method. The uncured coating material is applied to the substrate, followed by the expulsion of air from the coating. The coating is then cured by directing the radiant energy through the substrate from the surface opposite the surface having the coating thereon to contact the radiation-curable coating. ＜img id="iaf01" file="imgaf001.tif" wi="155" he="88" img-content="drawing" img-format="tif" /＞

[Goldberger, William Morgan, Reed, Allan K.] 120 South Riverside Plaza, Chicago Illinois 60606, US This invention relates to the production of granular graphitic carbon materials containing metallic elements dispersed throughout the graphitic structure. More specifically, products contain elements that enhance the controlled nucleation of dissolved carbon during the solidification of molten cast irons and are of particular value in the manufac­ture of quality iron castings. Moreover, the chemical form of the selected metallic elements and their high degree of dissemination within and throughout a graphitic carbon structure has been shown to provide special properties that increase the controlled nucleating or "inoculating" ability of the products of this invention over that obtained by use of the components added individually or in a simple mixture to molten cast iron.

[Lopez de Romana, Eduardo Agustin] The present invention relates to a method and means for monitoring the focussing condition of the writing light beam impinging the writing surface of a recording medium. Systems for monitoring the focus condition of a light beam used in reproducing prerecorded information from a videodisc by a videodisc player operate by splitting off reflected light from the incident light beam path in a region where the incident beam is diverging. In this manner, the reflected beam entering the polarizing cube, placed in the diverging portion of the incident beam, produces a converging light beam diverted to the photodetector. Because of numerous problems in attempting to apply player concepts to writing machine, it has been common practice in the prior art of recording laser discs to periodically determine optimum focussing position for the various optical elements affecting focus by producing a series of test discs and playing back each disc or portion thereof corresponding to a particular combination of settings for the various optical parameters such as power and focus involved. The empirically derived conditions necessary to produce acceptable focussing conditions, however, are extremely costly due to the labor time involved in setting up and determining the optimum focus conditions as well as in the loss of videodisc production due to down time of the mastering machine. The present invention operates on the recognition of the fact that, although for all practical purposes a light beam from a laser device is collimated, it, in fact, is very slightly divergent as it emerges from the laser resulting from diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exiting the laser tube is slightly divergent, the reflected light from the videodisc, even though small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator to effect monitoring of the focus condition of the writing beam.＜img id="iaf01" file="imgaf001.tif" wi="77" he="38" img-content="drawing" img-format="tif" inline="no" /＞

[Weihrauch, Georg, Kaiser, Hans-Rolf, Dr. Ing.] Kleiderbügel, bestehend aus einem Bügelkörper aus Holz, Kunststoff oder dgl. und einem Aufhängehaken (1), der aus einem Profildraht gebogen, an seinem Ende mit einem rillen­artigen Profil (5) mit jeweils einer den Umfang des Profildrahtes überragenden Rillenschulter versehen und durch Einschlagen dieses Endes an dem Bügelkörper widerhakenartig befestigt ist. Um solche Aufhängehaken mittels linearer Umformbe­wegungen, z. B. durch Stanz- und/oder Prägewerkzeuge er­zeugen zu können, ist das Profil aus nicht umlaufenden Nuten gebildet, deren Nutengrund linear verläuft und im wesentlichen einer Sekante des vorzugsweise runden Draht­querschnittes folgt.
