Abstract: A machine for punching holes in batches of sheets has a receptor which holds a stack (49) of sheets in vertical position. A timing mechanism sequentially jogs and segregates a first batch (124) from the receptor and deposits same in a vertical punch slot (207). At the bottom of the punch slot (207) is a horizontally reciprocating punch which forms the holes. Meanwhile, a second batch (125) is being jogged and segregated. The first and second batches (124, 125) are gripped and lifted. The first batch (124) is deposited in a vertical discharge slot from which it is transferred to a deposit tray. The second batch (125) is simultaneously punched while in the punch slot (207).

Abstract: A method for removing hydrogen chloride from an exhaust gas discharged from an incinerator, which comprises the steps of: causing hydrogen chloride contained in an exhaust gas discharged from an incinerator to react with slaked lime in slurry into basic calcium chloride; detecting a concentration (y) of hydrogen chloride remain­ing in the exhaust gas after the reaction with slaked lime; determining a deviation (Δy) of the thus detected concent­ration (y) of hydrogen chloride from a predetermined target concentration (y o ) thereof; determining a corrected deviation (Δy′) by adding to the above-mentioned deviation (Δy) a correction value (Δy₁) calculated in accordance with the following formulae: 
    Δy₁ = -G p (S)(1-e -LS )U      (1) 
    Δy′=Δy +Δy₁        (2) 
where, 
    G p (S) : a transfer function representing a first order lag, 
    e -LS  : a transfer function representing a dead time, and 
    U : a target amount of supply of slaked lime,   which renders the deviation (Δy) zero; 
determining a target amount of supply (U) of slaked lime, which renders the thus determined corrected deviation (Δy′) zero; and adjusting an amount of supply of slaked lime so that the amount of supply of slaked lime agrees with the thus determined target amount of supply (U) of slaked lime; thereby removing hydrogen chloride from the exhaust gas discharged from the incinerator.

Abstract: Un système de séparation continue de matière de densité intermédiaire et plus légère, telle que du plasma riche en plaquettes sanguines à partir de sang entier envoie du sang au travers d'un intervalle de centrifugation divergent (65) entre des parois interne et externe d'un rotor (42) tournant autour d'un axe central à l'intérieur d'une enceinte. L'action de centrifugation crée un écoulement stratifié le long d'une section intermédiaire. Cependant, en créant des sillons de fuite dans l'intervalle entre le rotor (42) et l'enceinte (11), des configurations de remélange localisé tendant à se déplacer dans la direction opposée sont induites dans la matière stratifiée. Du plasma riche en plaquettes peut ensuite être extrait au travers d'orifices adjacents (58) de concentré de plaquettes, lesquels orifices sont ménagés sur la paroi intérieure du rotor (42). Un système à passage intérieur fait passer le plasma riche en plaquettes vers un réservoir (23) de concentré de plaquettes. La recirculation du sang dans l'intervalle rotor-enceinte entre la sortie et l'entrée, et l'action de pompage effectuée par l'intervalle de centrifugation divergente (65) contribuent à améliorer les niveaux de débit et de concentration. Une section initiale à intervalle étroit est placée avant l'intervalle de centrifugation (65) de manière à limiter la propagation vers l'arrière de configurations circulatoires induites.
