Patent CA-2200182-A1 (CA)
Title: Paper products containing a vegetable oil based chemical softening composition
Inventor: PHAN DEAN VAN
IPC: D21H21/24
Filed: 1995-09-14
Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include dioleyldimethyl ammonium chloride (i.e., di(octadec-z-9-enyl)dimethylammonium chloride) (DODMAC) and dierucyldimethyl ammonium chloride (i.e., di(docos-z-13-enyl)dimethylammonium chloride) (DEDMAC). Depending upon the paper product characteristic requirements, the saturatiuon level of the fatty acyl groups of the vegetable oils can be tailored. Variables that need to be adjusted to maximize the benefits of using unsaturated vegetable oil based acyl groups include the Iodine Value (IV) of the fatty acyl groups; and the cis/trans isomer weight ratios in the fatty acyl groups.

Abstract: A method of cooling steel sections which are hot from rolling by means of shock-like cooling following the rolling process so as to form a martensitic surface layer, and by subsequently autogenously tempering this surface layer by means of core heat to obtain a tough-resistant structure with an austenitic remaining cross-section, wherein the method is used in connection with types of steel which, with uncontrolled cooling in air, would directly transform from the austenitic phase into martensite because of their alloying elements from the group Cr, Mn, Mo, Ni and other suitable elements.

Abstract: To discriminate optically between the various phases in a three-phase fluid, a light beam (F) of non-zero divergence is injected into a detector block (10) made of a material whose refractive index is greater than the refractive indices of all three phases of the fluid. The block (10) has a sensitive zone (18) and a total reflection zone (20) such that incident rays (Ri) parallel to the axis (12) of the block strike the sensitive zone (17) at an angle of incidence (.theta.i) and are returned parallel to the axis (12) by the total reflection zone (20). The angle of incidence (.theta.i) is such that a first phase gives rise to almost total reflection, a second phase gives rise to almost total transmission, and a third phase gives rise to partial transmission and partial reflection.

Abstract: A valve member (40) includes a wedge shaped obturator (42) having sealing regions (46, 48). Below dashed lines Al-Al/A2-A2, the obturator comprises a part-circular-cylindrical outer surface with the axis of the cylinder ex-tending perpendicularly to a stem (12) and in-clined planes (43, 44) being tangential to the outer surface. A butt seal region (50) of the obturator includes a central region (52) which extends parallel to the axis of the cylindrical surface. Adjoining regions (54, 56, 58, 60) ex-tend from the region (52) across the cylindrical surface, obliquely to the axis thereof, so as to meet the sealing regions (46, 48). Thus, faces of the wedge above lines At-Al/A2-A2, blend into the cylindrical surface below the line so that there is a smooth transition between sealing re-gions (46, 48) and the butt seal region (50). In another embodiment described, an obturator in-cludes two part-circular-conical surfaces spaced apart by an arcuate surface instead of the part-circular-cylindrical outer surface of valve mem-ber (40).

IPC: G02B6/28
Filed: 1998-08-21
Abstract: A twin coupler system includes first and second optical couplers that couple a multimode pump fiber into a double-clad active primary fiber. The pump fiber carries multimode pump power from a multimode source. The primary fiber, on the other hand carries optical information signals on the single mode core that are amplified through the pump power. A system and method for manufacturing the twin coupler system constructs the first coupler by preparing first portions of the primary and pump fibers for coupling and performing fusion and tapering operations on the primary and pump fibers at the first portions and constructs the second coupler by preparingsecond portions of the primary and pump fibers for coupling and performing fusion and tapering operations on the primary and pump fibers at the second portions. The fusion and tapering operations at the second portions are dependent upon the fusion and tapering operations performed at the first portions so as to achieve a maximum coupling efficiency of the pump power from the pump fiber to the primary fiber for the entire twin coupler system.
