Title: Large crystal zsm-5, its synthesis and use
Inventor: WENTZEK STEVEN EDWARD
IPC: C07C2/00
Filed: 1996-06-06
Abstract: In a synthetic porous crystalline material having the structure of ZSM-5 and a composition involving the molar relationship:  X2O3:(n)YO2, wherein X is a trivalent element; Y is a tetravalent element; and n is greater than about 12, the crystals have a major dimension of at least about 0.5 micron and surface framework YO2/X2O3 ratio which is no more than 20 % less than the bulk framework YO2/X2O3 ratio of the crystal. The material is synthesized using an amino-acid as a directing agent.
Patent CA-2229118-A1 (CA)
Inventor: PEIFFER ROBERT E
IPC: D21H25/16
Filed: 1998-02-09
Abstract: A pre-metering rod is located between a coating applicator and an air knife, and replaces the smoothing roll in some existing air knife applications. The pre-metering rod consists of a small diameter rod of about one and one-half inches in diameter that rotates at 10-500 rpm against the direction of the coating layer on the web. The web is wrapped around a portion of the circumference amounting to about twenty-five degrees of the rod's surface as it travels over the rod. The rod is supported in a rod holder supported on a support beam. Actuators move the support beam away from the web for threading and maintenance, and towards the web to engage the rod with the web. The combination of the rod diameter, the amount of wrap on the rod, and the speed of the rod rotation determine the amount of pre-metering of the coating, which determines the thickness of the coating layer on the web that is presented to the air knife section. As a result, the thickness of the coating layer can be decreased. Decreasing the mass of the coating presented to the air knife decreases the momentum of the coating layer and allows the speed of the web to be increased to over 2,000 feet per minute as it passes through the air knife section.
Patent CA-2229748-A1 (CA)
Inventor: GUENAT JEAN-MARC
IPC: A61C13/265
Filed: 1998-02-17
Abstract: The device for the attachment of dental prosthesis comprises a male component (1) which can be anchored into the jaw and a removably attachable female component (2) for receiving a core, whereby the male component (1) includes a retention groove (7) and the female component (2) includes a spring element for retaining the male component (1) in the groove, whereby the spring element is a rubber elastic retention ring (3). The latter is arranged in such a way in the male component (2) that in its axial direction it is neither moved during the introduction of the male component (1) nor during its extraction and is untwistably hold. To avoid an overpressure during assembling and a vacuum during disassembling, its inner wall comprises a venting groove (15). Such a fixation means allows a smooth snapping-in and a user-friendly disassembling of the prosthesis, which will, however, be hold tightly in its axial direction.

Patent CA-2243571-A1 (CA)
Title: Process and device for determining an analyte contained in a scattering matrix
Inventor: ESSENPREIS MATTHIAS
IPC: G01N21/49
Filed: 1997-01-23
Abstract: A process is disclosed for determining an analyte in a scattering, in particular biological, matrix. In a detection step, detection measurements are made: light (primary light) is directed into the matrix (6) and light (as secondary light) emerging from the scattering matrix is detected to determine as a measured quantity a measurable physical characteristic of the light which can be altered by the interaction between light and matrix (6). In an evaluation step, data is obtained on the presence of the analyte in the matrix (6). The determination of optically weakly absorbing analytes against a strongly absorbing interfering background is improved by the use in combination of two selection processes for detecting the secondary light. In the first, the primary light (14) is focused by an optically focusing element (16) onto a focal region (17) located inside the matrix (6) at a specified measurement depth (d); the focal region (17) is focused by an optically focusing element (16, 21) onto a light inlet aperture (24) situated in the path of the secondary light (19) to the detector. In the second selection process, another depth-selection means, preferably a low-coherence measurement process, is used to detect light (secondary light) reflected from a defined measurement depth, the measurement depth corresponding to the focal depth.

Filed: 1999-07-15
Abstract: The novel design of a surface ionization detector, for detecting trace amounts of organic molecules, for hand portable use, including a bifilar filament, rigidly supported at both ends and mounted on the same rigid base with a screen cathode, thus ensuring mechanical stability and reproducibility of measurement. The use of very small diameter wire for the filament provides a large surface/mass ratio, has lower power consumption and yet provides adequate sensitivity. An alternative approach for even lower power consumption is the use of a filament composed of a thin metal film deposited on a non-conducting substrate, such as quartz. The provision of multiple filaments, of different metals used simultaneously and sequentially, allows for improved detection and identification of species, or for longer detector lifetime.
