Patent CA-2113040-A1 (CA)
Inventor: HAKALA HARRI
IPC: B66B11/00
Filed: 1994-01-07
Abstract: In this invention, an elevator motor (6) provided with an external rotor (17) and a traction sheave (18) is so implemented that it simultaneously constitutes the counterweight (26) of a rope-suspended elevator (1). In this motor/counterweight structure, rotating induction motors can be used. A gear is not necessary because the construction of the invention and the placement of the motor allow the use of a motor with a large diameter and therefore a high torque. As the length of the motor still remains small, the motor/counterweight of the invention can be accommodated in the space normally reserved for a counterweight in an elevator shaft. <IMAGE>

Abstract: APPARATUS AND METHOD FOR PREFERENTIALLY SEPARATING VOLATILIZABLE COMPONENTS OF A MATRIX An apparatus and method are disclosed for preferentially separating a high vapor pressure component from a low vapor pressure component, wherein at least a portion of each component is volatilized from a matrix. A matrix, such as a sludge contaminated with volatilizable organic materials, is directed through a housing by a screw conveyor. Heat is applied to the matrix in an amount sufficient to volatilize at least a portion of the high and low vapor pressure components. A portion of a high vapor pressure component volatilizes at an inlet end of the housing while a portion of a low vapor pressure component volatilizes at an outlet end of the housing. The volatilized components are then preferentially separated by a hot gas, which is discharged over the matrix from a gas inlet tube, through separate outlet ports. The volatilizable components of the matrix are thereby preferentially separated.
