Patent number: 4257818Abstract: Continuous hydrolysis to produce sugars is effected by cyclically immersing a solid, divided lignocellulosic material in a bath of concentrated hydrochloric acid and draining the material between successive immersions so as to dissolve the produced sugars, until the sugar concentration of the acid in the bath has attained a desired value.The solid material and the liquid acid are delivered to a tubular horizontal rotary reactor arranged to provide a bath of the acid, to produce a rotating movement for cyclical immersion of the solid material in the bath of acid and longitudinally displace the solid material undergoing hydrolysis together with the acid of the bath and to continuously discharge solid residue and acid containing dissolved sugars due to overflow by gravity at an outlet end of the reactor.Type: GrantFiled: April 24, 1979Date of Patent: March 24, 1981Assignee: Battelle Memorial InstituteInventors: Alain Regnault, Jean-Pierre Sachetto, Herve Tournier, Thomas Hamm, Jean-Michel Armanet

Patent number: 4154258Abstract: The invention relates to an apparatus for introducing water-soluble substances, especially plant treatment substances, such as fertilizers, plant protectives, weed killers and the like, into a water stream, the apparatus having a casing for carrying a water stream and a container for taking up said substances. The container is arranged within said casing for rotation around a rotational axis and has a completely closed peripheral wall, laterally limiting the interior of said container, and has a completely closed bottom wall section. At least one opening is provided at the upper side of said container, the edge of said opening being nearer to the rotational axis of the container than at least a part of the inner surface of the peripheral wall, said part being arranged in between the bottom wall section and the opening.Type: GrantFiled: December 1, 1977Date of Patent: May 15, 1979Inventors: Hubertus Duda, Fritz M.

Patent number: 4127388Abstract: Apparatus for contacting fused solid materials with solid, liquid or gaseous materials, comprising a rotary drum, longitudinal baffles along the inner drum wall inside the apparatus, coaxial consoles being joined in a liquid- and gas-tight manner to faceplates of the drum, for lodging feeding and removing mechanisms. It is a major feature of the invention that a diverter baffle system is mounted from the consoles throughout the interior length of the drum. Two preferred embodiments are described: one for formulating plant protecting agents, wherein the baffle system includes a row of diverting baffles that can be pivoted inside the drum. The other preferred embodiment is suitable for extracting vegetable materials, and here the baffle system is constituted by a stationary drum having a slanting lapping formed therein, similarly pivotable diverting baffles being arranged along the lapping. Various additional and some optional structural features are disclosed for both apparatus embodiments.Type: GrantFiled: August 11, 1976Date of Patent: November 28, 1978Assignee: Alkaloida Vegyeszeti GyarInventors: Gabor Maczko, Dezso Tobias, Laszlo Bozzay, Miklos Takacs, Rudolf Kovesdi
