Patent EP-0450101-A1 (EP)
Inventor: OHTSUJI MASAAKI
IPC: B65G33/16
Filed: 1990-10-25
Abstract: The flexible screw in accordance with the present invention is equipped with a flexible rod and a cord disposed helically on the rod. The screw can be arranged not only in a linear transfer line but also in a curve transfer line. Therefore, it is possible to make container transfer smooth and simplify the construction of a container transfer apparatus, thereby reducing the installation cost. It can also reduce wear of the pipe in the transfer of powder or granules. A container transfer apparatus of the present invention includes an arrangement in which the screws described above, or the screw and a guide, are spaced apart in parallel to transfer containers held between them by rotating the screw. The container transfer thus can be made smoothly even in a curve line. Moreover, the maintenance cost of the screws can be reduced and wear of rails can be limited considerably, as well. The transfer apparatus for powder and granules in accordance with the present invention can reduce wear of the pipe.

Inventor: GLEIM GUENTER
IPC: H02P6/15
Filed: 1990-12-18
Abstract: An electronically commutated motor is controlled by controlling the winding current of the motor. During an operational mode change of the motor, the winding current is first changed to a value in excess of the value needed to maintain a measured motor parameter at a desired level. When the desired level of the parameter is reached the current is changed to the value needed to maintain the parameter at the desired level. In addition, the communication time of the motor is shifted such that the temporal maximum of the magnetic field of the motor coincides with the position of the motor poles which results in attainment of a maximum speed altering force.
