  • Automatic wire-threading device for electroerosion machines
    Patent number: 5471025
    Abstract: An automatic wire threading device with a threading mechanism having a first free wheel and a second free wheel each having an inner traction surface and an outer traction surface. When a central processing unit (4) detects wire breakage, drives a pneumatic cylinder (25) against the action of a spring (22) that separates the free wheels so that pivoting arm (23) positions the wheel carried by it against the other wheel. The central processing unit then orders rotation of a threading motor which by a gear train drives the wire. A cutting mechanism cuts the wire to improve threading. A guide water circuit is provided downstream of the cutting mechanism.

  • Chess clock
    Patent number: 5420830
    Abstract: A clock, especially suitable for playing the game of chess, includes the standard two clock face system with an activation button for each player. A delay feature is included so that there is a delay between the time the activation button is pressed and the time that the activated clock actually commences movement.

  • Method for detecting pinholes in continuously cast billets
    Patent number: 5363901
    Abstract: Continuously cast metal billets are continuously passed by a symmetric light source comprising a plurality of single light sources arranged in a circle or in another way such that the light falls substantially symmetrically on the part of the surface of the metal billet which is to be detected in such a way that the surface of the metal billet which faces the light source is illuminated except for pinholes. Reflected light from the surface of the billet is detected by a linescan camera arranged centrally in relation to the light source, which camera has a scanning direction normal to the direction of movement of the metal billet, whereby pinholes are detected by registration of reflected light intensity below a preset threshold value.

  • Ferrophosphorus refining process
    Patent number: 5362440
    Abstract: The ferrophosphorus refining method entails forming a ferrophosphorus melt and adding an oxidizing agent to the melt to oxidize the impurities in the melt. The oxidized impurities then rise to the top of the melt and either go into the slag or escape in a gaseous forte. The slag is removed and a refined ferrophosphorus is recovered. Suitable oxidizing agents include solids such as ferrous oxide (Fe.sub.2 O.sub.3), ferric oxide (Fe.sub.3 O.sub.4), ferrous-ferric oxide (FeO), mill scale, limestone, dolomitic limestone, lime and any alkalide carbonate; and gaseous oxidizing agents such as oxygen, air and mixtures thereof.
