Title: Filter device
Inventor: OIGEN MORITSUTSU
IPC: B01D29/21
Filed: 1980-04-03
Abstract: A filter device exhibits a chamber with a spiral which revolves helicoidally about the chamber axis. The spiral is constituted by a channel-shaped support which holds taut a filter constituted by a spiral-shaped tube. During the filtration of a suspension the liquid component of the suspension passes through the filter into the channel-shaped support and from the latter to a filtrate outlet. Because at least that part of the filter effective for the filtration forms a substantially smooth fold-free surface, uniform utilization of the total effective surface of the filter is possible. The solid residue deposited upon the surface of the filter can also be transported out of the chamber without difficulty by rotating the spiral.

Abstract: PURPOSE: To maintain a power in the case of driving a cage of an elevator in an upward direction actually constant for any load by using a method and an apparatus for saving electrical energy in a hydraulic elevator drive. CONSTITUTION: A maximum nominal speed in an upward direction is selected for a load which typically occurs most frequently and the drive is designed accordingly. A size required for the drive is designed in response to this selection. A hoisting speed is reduced in response to a high load, and increased in response to a low load. A means for realizing a variable hoisting speed is achieved either through a use of an adjustable pump 8 to be controlled by a pressure adjusting valve 14 with variable displacement volume or through a use of a positive displacement pump of constant displacement volume which is driven by a frequency regulated electrical motor. A rotating speed of the motor is steplessly adapted in response to a load applied at present.
