. Pulp and paper magazine of Canada. forest fire,has just been completed by the Vitagraph Companyof America in co-operation with tiie Pennsylvania De-partment of Forestry. October 1. 1916. PULP AND PAPER MAGAZINE A New Type of Beating Engine Translated from Papir Journalen Christiana. Nor-way, by Newsprint Mfgr. Association. To the many new types of beaters, which ilurin<r thelater years endeavors for a more effective pulp treat-ment have brought about, a new type has been added,the so-called Rabus beater (named after the Ger-man engineer Rabus), which in our opinion deservesattention. We therefore, present below an illustra-tion of the same with a short report. The machine differs from those hitherto generallyin use therein, that a large IoU of great diameter isplaced at the end of s])iral shaped trough and thepulp is carried over the roll to the beginning of thespiral. In addition the trough has a channel running inscrew form around the circle shaped centre wall. Inthis way the pulp is not hindered by the sharp and. untoward curve which it encounters in machines witha straight partition. A further point of advantage consists therein thatthis machine turns the pulp, that is, the pulp com-ing from the outside wall is carried against the centreand vice versa every time it lias passed the roll bywhich an extraordinary mixing of the indj) and a spec-ially uniform dissolving is effected. The bed-plate is placed at the lowest part of thetrough so that the pulp flows there by iteslf, fromwhich it will be seen that the machine works alreadyfrom the beginning of the filling up. whereas in thecase of machines of ordinary construction the pulpmust rise up to the higher placed bed-plate in orderto be caught by the roll. The emptying of the machine will therefore take~ace much more easily and quicker. On account of the qualifications here mentioned thismachine can be used well filled and with 14% .sub-stance contents will make feet speed, with 8-9% substance content a s
