Patent CA-2055756-A1 (CA)
Inventor: TSANG CHIH-HAO
IPC: B01D53/94
Filed: 1991-11-18
Abstract: In a preferred method, particles of amorphous silica are used to provide a silica coating suitable for carrying dispersed catalyst particles for the treatment of diesel engine exhaust emissions.  The silica coating is formed from a mixture consisting essentially of two groups of the fine silica particles of respective average sizes and size ranges which are virtually non-overlapping.  The particles of the first of the two groups have a first average size sufficient to permit the particles of the first group (smaller group) to occupy voids between the particles of the second group (larger group) in a packed arrangement, and preferably the second group has a second average size which is at least 20 times greater than the first average size.          Although particles of amorphous silica are preferred for use in forming a coating with improved adherence suitable for the treatment of diesel exhaust, the method of the invention is also useful to improve the adherence of coatings formed of other ceramics, such as alumina, titania, zirconia and zeolite.

Title: Optical fiber package and methods of making
Inventor: FRITZ DOUGLAS E
IPC: G02B6/44
Filed: 1992-05-25
Abstract: A package (20) Or wound optical fiber (22) includes a spool (23) on which are wound a plurality of layers with each layer comprising a plurality of convolutions of the optical fiber. The winding is accomplished such that each successive convolution is spaced from a preceding convolution. The spacing is such that on the third and further outer layers, each optical fiber is tangent to each of two adjacent convolutions of a previously wound layer and to one convolution of the next inner layer. Also, each convolution in each layer after an innermost layer crosses transversely optical fiber of an immediately preceeding layer in two relatively closely spaced locations and such that crossovers in successive layers are staggered circumferentially of a winding surface. Because of the nesting which is caused to occur, excellent density, package rigidity and stability are achieved. Further, winding abnormalities such as crossovers are substantially reduced, resulting in a package of optical fiber which exhibits very low loss due to winding.
