Patent CA-2218326-A1 (CA)
Inventor: MCGREER KENNETH A
IPC: G02B5/18
Filed: 1997-10-16
Abstract: A reflective-type diffraction grating is formed by an array of grooves, each groove comprising two reflective facets and a riser. The two reflective facets of a single groove are oriented so that some of the light rays incident on the groove reflect once off each facet. The riser joins one of the reflective facets within one groove to one of the reflective facets in an adjacent groove and is not designed to reflect light incident on the groove. In one embodiment that is particularly suited to the Littrow mount or the Eagle mount, the reflective facets are oriented at right angles so that the grooves will retroflect the incidence light rays. In one embodiment that is particularly suited for integrated optical demultiplexer, theinterface between two dielectric media is used for the reflective facets and theincident light propagates through the medium with the higher index of refraction so that the reflective facets may reflect light predominantly by means of total internal reflection.

Abstract: A chromatographic assay test device for use with immunoassays. The test device has a sample collection member pivotally coupled to a test strip receiving member. The sample collection member has a window for applying a test sample to a pad accessible through the window and the pad is repositionable to an inverted position to contact a chromatographic member inserted into the test device. The chromatographic member is then brought into opposition to the sample collection member thus improving test performance by reducing the manipulation of samples. The test device is constructed from five interconnected panels which are die cut from SBS cardboard. The first panel (12) has a window (14) for inserting a test strip and the second panel (20) has a window (22) for viewing the test strip during the test procedure. The third panel (30) has the repositionable pad section. The fourth panel (40) has a window (42) for applying the test sample and the fifth panel (50) covers the test sample window (42). The first and second panels are coupled to form a first planar member and the third and fourth panels are coupled to form the sample collection member. The fifth panel includes a reusable adhesive for securing the fifth panel over the sample window in the fourth panel.

IPC: E21B47/022
Filed: 1998-10-19
Abstract: The position of a boring head (16) during boring operation in the vicinity of an existing utility conveyance (22) that radiates a locating signal can be determined by establishing the ratio of the strength of the locating signal of the cable induced in the boring head to the strength of the locating signal on the conveyance. Should the ratio exceed a prescribed value, indicating that the boring head is too close to the existing conveyance, then an alert is generated. Advantageously, the position of the boring head during a boring operation may be controlled in feed-back loop fashion in accordance with the ratio to maintain the boring head substantially parallel to the existing conveyance.

Title: Liquisolid systems and methods of preparing same
Inventor: BOLTON SANFORD M
IPC: A61K9/10
Filed: 1997-06-09
Abstract: Liquisolid systems are acceptably flowing and compressible powdered forms of liquid medications. According to the concept of liquisolid systems, liquid liphophilic drugs or water-insoluble drugs dissolved in suitable non-volatile solvents may be converted into free-flowing and readily compressible powders by simple admixture with selected powder excipients referred to as carrier and coating materials; a schematic outline of steps may be drawn for the process.  Various grades of microcrystalline or amorphous cellulose may be used as carriers, whereas very fine particle size silica powders may be used as coating materials. Based on the theory that the carrier and coating materials can retain only certain amounts of liquid and at the same time maintain acceptable flow and compression properties, a new formulation-mathematical model is provided to calculate the optimum quantities of carrier and coating materials required to yield acceptably flowing and compressible liquid/powder admixtures.
