Patent FI-800501-A (FI)
Inventor: SCHULTZ PETER CHARLES
IPC: C03B37/075
Filed: 1980-02-20
Abstract: A preform is formed by providing a substantially longitudinally continuous core member (10) and affixing it to a starting member (12). Particulate material is applied to the exterior surface of the core member to form an adherent coating (18) having an index of refraction less than that of the core member (10). The starting member (12) and the core member (10) are longitudinally translated while simultaneously applying the adherent coating (18) of particulate material to the core member to form a continuous and substantially homogeneous adherent coating of substantially uniform thickness. The composite so formed is simultaneously or subsequently heated to sinter or consolidate the applied adherent coating thereby forming a solid blank which may be heated to the drawing temperature of the material thereof and drawn to reduce the cross-sectional area thereof forming a substantially continuous optical waveguide, the core member (10) comprising the core while the consolidated coating (18) comprising the cladding of the optical waveguide. The adherent coating (18) may be sintered or consolidated to form a solid blank and thereafter drawn in a separate operation or subsequently drawn as part of a continuing operation. As an alternate, the optical waveguide may be drawn immediately following the sintering or consolidation step employing a single heating of the structure.

Abstract: The invention relates to a process for preparing olefins from heavy oils. The heavy oil which is supplied is firstly cracked at high temperatures, and during short drill times, and then separated into three fractions consisting of light, medium-heavy and heavy oils. The light and medium-heavy fractions are cracked in parallel streams. These cracked streams are combined and subjected to further cracking in order to produce olefins. The invention also relates to an appliance for implementing the process. <IMAGE>

Abstract: A digital phase comparator measures the phase difference of two signals (S1, S3) from a third signal (S2), and calculates the difference. The zero crossing of the two signals respectively sets two flip-flops (11, 12). If both flip-flops are set, they are simultaneously reset with a delay. Each set flip-flop enables a corresponding counter (13, 14). An evaluation unit averages the counter outputs at major intervals. The phase comparator can be incorporated into a phase-locked loop.

Title: Improvements in the heat treatment of steel
IPC: C21D1/76
Filed: 1921-01-10
Abstract: 176,576. Kubasta, J. C. M. Jan. 10, 1921. Cementation.-In heat-treating steel, the formation of a soft skin due to decarburization of the surface layer is prevented by carrying out the beating-process in the presence of oxidizing gases, preferably oxygen, in sufficient quantity so that not only is the carbon removed but the iron in the surface layer is converted into ferrous or ferric oxide so that the new metallic surface is of normal carbon content. The steel is heated in a soft-iron vessel and when the first critical point is reached, oxygen is supplied. After the treatment is completed, the supply is continued to flush out the gases liberated and then stopped. The oxygen remaining is consumed by conversion of the ferrous oxide produced into ferric oxide and, owing to a vacuum being produced, air is drawn into the heating-vessel the oxygen of the air being similarly consumed leaving an inert nitrogen atmosphere in which the cooling is completed.
