Abstract: The optical interface (28a-h) comprises an optical transmitter section (65,65a,75,125,135,145) and an optical receiver section (200). The optical transmitter section (65,65a,75,125,135,145) receives data in an (NRZI) format from a LAN controller when the interface (28a-h) is part of a remote node. The transmitter section (65,65a,75,125,135,145) converts the non-return to zero inverted data to an AMI format. An LED driver circuit (135) smooths out and extends the AMI data and uses it to drive an LED (160). The LED driver (135) alternately drives the LED (160) from a fifty percent reference output level to zero percent output and one hundred percent output corresponding to alternate positive-going and negative-going transitions of the data. The receiver section (200) has a light sensitive detector and preamplifier (202) which receives optical signals encoded with digital data and generates corresponding electrical signals which are processed by a peak pulse detector (224) of the type used to detect signals generated by the read/write heads of magnetic disk media. The disk pulse detector (224) generates unipolar digital signals corresponding to the AMI signals. A decoder (320) converts the unipolar digital pulses to NRZI format. The NRZI data is communicated to a LAN controller when the optical receiver is part of a remote optical interface (28a-h) and to conventional LAN hub circuitry when it is part of a hub optical interface. The LED driver circuit (135) comprises the entire transmitter section of a hub optical interface and receives data for transmission directly from the hub LAN circuitry.

Abstract: Un signal diffus est produit à partir d'une lumière diffusée par un précipité formé par une réaction chimique et par des sources de diffusion non spécifiques. Un signal de suppression est produit pour un signal diffus provenant d'une lumière diffusée uniquement par des sources de diffusion non spécifiques qui contribuent au signal diffus, et le signal de suppression est soustrait du signal diffus pour produire dynamiquement un signal indicatif de la différence entre les signaux diffus pour réduire les effets des sources de diffusion non spécifiques lors de la détermination de la vitesse de changement de la lumière diffusée par le précipité. L'un des signaux diffus peut être stocké puis combiné avec l'autre, ou bien les signaux peuvent être mesurés simultanément puis combinés.

Abstract: To produce smelting materials based on copper and chromium, an electric arc-smelting process is applied, in which the electrode material melting off from a consumable electrode of predetermined empirical composition is collected in a water-cooled mould for cooling without macroscopic segregation of copper and chromium. For smelting the material with a further readily volatile component, a consumable electrode is used according to the invention, which partially consists of a solid alloy of copper with the readily volatile component, the concentration of the readily volatile component in the alloy being higher than in the empirical composition of the smelting material, and the readily volatile component remains bound in the smelting material during the smelting. In the appropriate consumable electrode, which specifically consists of copper and chromium as well as tellurium and/or selenium and/or antimony as the readily volatile component, the latter is at least partially alloyed in the copper as an intermetallic compound, the copper-tellurium alloy or copper-selenium alloy or copper-antimony alloy being present as a compact part in the electrode structure.
