Patent CA-2041488-A1 (CA)
Inventor: GALEA JOSEPH M
IPC: A47C7/24
Filed: 1991-04-30
Abstract: ABSTRACT          The  present  invention  relates  to  a  spring assembly for the seat portions or areas of upholstered furniture.   The spring assembly provides a frame and a series of different spring types supported in a generally parallel arrangement within the frame.  The spring assembly includes a plurality of upper spaced,  elongate sinuous springs extending between and above a pair of opposing front and back members.  Located in the central region of the assembly is a rectangular quad coil spring mounted on the  two upper  and  lower wire  stringers.    The  spring assembly is provided with a pair of  Z-shaped  sinuous springs, one located on each lateral side of the quad coil.          The Z-shaped springs are mounted on lower elongate sinuous springs extending between the front and back members.  The upper portions of the Z-shaped sinuous springs and the upper elongated sinuous springs are secured to the upper and lower stringers for stability and to prevent lateral movement of same.  The Z-shaped springs provide for local support independent of the central quad coil.  The spring assembly provides a differential response across the top surface thereof in response to a user sitting thereon.          When  several  such assemblies are mounted adjacent one another,  the  resulting  system  provides  for  relative independent spring support between adjacent users.

Patent CA-2051529-A1 (CA)
Inventor: AKETAGAWA KEN-ICHI
IPC: H01L21/20
Filed: 1991-09-17
Abstract: A thin film deposition method involves placement of a wafer or substrate having a surface containing at least two types of materials inside a vacuum chamber or vessel and introducing a reactant gas into the vacuum chamber or vessel. The reactant gas contain molecules that have a low adhesive coefficient relative to at least one of the at least two types of materials. This allows epitaxial growth to occur on the other type of materials contained in the wafer or substrate. The method further includes setting the pressure inside the vacuum chamber or vessel filled with the reactant gas equal to a pressure range in which the mean free path (d) of the reactant gas molecules is longer than the shortest distance (L) between the wafer or substrate placed inside the vacuum chamber or vessel and the vacuum side-exposed wall of the vacuum chamber or vessel, such that d > L. The method further includes cessation of the reactant gas into the vacuum chamber or vessel until the total amount of the reactant gas introduced into the vacuum chamber or vessel reaches a level at which a thin film can be deposited onto the surface containing the material having the low adhesive coefficient relative to the reactant gas.

Title: Production of synthetic rutile
Inventor: HOLLITT MICHAEL J
IPC: C22B3/08
Filed: 1991-03-01
Abstract: The specification describes a process for producing synthetic rutile from a titaniferous ore or concentrate.      The process involves three basic steps which are reduction, removal of iron by leaching or aeration and removal of other impurities by leaching in a solution of a strong mineral acid such as hydrochloric acid or sulphuric acid. The conditions of reduction are controlled to promote the formation of metallic iron, a major rutile phase and a minor impurity bearing phase.      The minor impurity phase may be a metatitanate, an anosovite or a pseudobrookite. However, formation of a metatinatate is normally preferred. Suitable reductants include carbonaceous materials or hydrogen bearing gases such as natural gas or synthesis gas. The process is capable of removing more than 80% of each of the contained iron magnesium and manganese remaining as oxides after reduction. Substantial proportions of contained aluminium can also be removed.
