Inventor: HARTMANN ACHIM
IPC: C22B34/12
Filed: 1990-04-02
Abstract: The invention relates to a process for the removal of chlorine from off-gases which continuously or sporadically contain small amounts of chlorine, through scrubbing them with a ferrous chloride-containing aqueous solution in a scrubbing system. The solution used is obtained in dissolving a solids mixture which results from the chlorination of a titaniferous and ferriferous feedstock material and essentially contains-ferrous chloride. This solution is used in particular for the scrubbing of off-gases formed in the production of titanium dioxide by the chlorination of titaniferous and ferriferous feedstock material, thus generating titanium tetrachloride and ferrous chloride, and by the reaction of the titanium tetrachloride with oxygen-containing gases. It is preferably the solids mixture separated in this process from the chlorination mixture in a condensation step that is dissolved in the process of the invention, and at least part of the resulting solution is used for the scrubbing of the off-gas. Known devices can be used for scrubbing, e.g. packed columns.

Patent CA-2046149-A1 (CA)
Inventor: INAJI TOSHIO
IPC: H02P6/18
Filed: 1991-07-03
Abstract: This invention provides a brushless DC motor which does not have a position sensor for detecting a rotational point of a rotor.  Instead of using a position sensor, zero-crossing points of counter electromotive forces induced in the stator windings of the rotor are detected to obtain a pulse signal train.  From the pulse signal train thus obtained and a slant waveform signal generated in response to the pulse signal train, a position signal with a trapezoidal waveform is formed.  An electric current signal with a trapezoidal waveform is supplied to the stator windings of the rotor in response to the position signal thus formed for effecting an electric current switching of the stator windings smoothly, resulting in realizing a motor drive less in vibration and noise even when rotating at a high speed.

Title: Transport trailer structure for supporting canoes and other vehicles and loads, and methods of using such trailer structures
Inventor: MCCALLA WILLIAM R
IPC: B60P3/10
Filed: 1991-12-18
Abstract: ABSTRACT OF THE INVENTION        A transport trailer structure for carying vehicles such as canoes and other elongate loads has spaced apart carrier frames supported on a vehicle frame carried on wheels or other surface engaging members.  Vertically extending fore and aft guides extend upwardly from the vehicle frame, and slide bearings on the carrier frames are vertically slideable along the vertical guide members to permit the mobile carrier frames to move from positions of loading to positions of transport, and back again for unloading.  Collapsible spacers connect the carrier frames, and a cable wind-up and control system connects to the upper carrier frame at fore and aft locations and is operable to draw the upper carrier frame vertically from a lowered position in which loading of the upper carrier frame takes place to a raised transport position in which the collapsible spacers are restored to control the height to which the upper carrier frame may be raised.  Each subjacent mobile carrier frame is then loaded and raised incrementally until the next carrier frame is in loading position.  Unloading takes place in reverse order as the carriers are progressively lowered to unloading position.
