Patent CA-2320149-A1 (CA)
Inventor: WARD BILLY W
IPC: H01J37/317
Filed: 1999-02-09
Abstract: Particle beam systems and methods for interacting with a workpiece according to this invention include a work stage assembly and a first particle beam source. The work stage assembly is adapted a) for supporting a workpiece, b) for translating along a first axis, c) for translating along a second axis perpendicular to the first axis, and d) for rotating about a third axis perpendicular to both the first axis and the second axis. The work stage assembly has a work stage axis substantially parallel to the third axis. The first particle beam source for interacting with the workpiece is supported by the work stage assembly. The first particle beam source has a first particle beam axis. In one embodiment, the first particle beam source is oriented so that the first particle beam axis forms an angle with the third axis. In another embodiment, the first particle beam source is tiltable from a first position, with the first particle beam axis substantially parallel to the third axis, to a second position, with the first particle beam axis forming an angle with the third axis. Thus, the particle beam system can etch and image a vertical cross section of the workpiece without offsetting the work stage axis from the third axis.

Title: Battery cover structure
Inventor: TERASAWA DAI
IPC: G04C10/00
Filed: 2000-12-27
Abstract: A battery cover structure comprising an elastic sealing member having a large-diameter portion and a small-diameter portion, the large-diameter portion forming a peripheral flange portion around the small-diameter portion; and a rigid member joined to the elastic sealing member and located on a side of the small-diameter portion remote from the large-diameter portion, the battery cover adapted for attachment to a battery access hole in a watch case by inserting the elastic sealing member in the hole and engaging the peripheral flange portion with the case. Because of the rigidity imparted by the rigid member, the battery cover structure is substantially free from the risk of pushing the battery cover into the watch case to impede or damage the movement of the watch, or deforming the battery cover itself by excessive force to cause the battery cover to come off the battery case. Furthermore, the cover has an improved appearance. Also, the battery cover structure has a reduced risk of being easily detached and accidentally swallowed by a little child or the like, or to be removed unintentionally and lost by mishandling.
Patent CA-2329986-A1 (CA)
Inventor: LEHRACH HANS
IPC: C12Q1/6837
Filed: 1999-04-30
Abstract: The present invention relates to a novel method for the selection of clones of an expression library. The method is characterized by the step of analyzing for the expression of at least one (poly)peptide, such as a tag expressed in frame with a recombinant insert of said expression library, wherein said clones of said expression library are arranged in arrayed form. Screening for the expression of said (poly)peptide allows for the rearraying of clones that express the recombinant insert. Upon rearraying said clones, the library will now comprise clones having inserts in the correct reading frame to a very high degree. Optionally, the library is additionally screened for desired inserts either by contacting the expressed library with a ligand specific for the expression product or by hybridizing or fingerprinting the inserts with a nucleic acid probe.

Abstract: Void maintaining geocomposite laminates, and drainage systems utilizing those laminates, are provided for location below a road surface or below a large structure such as a building, retaining wall or parking lot. The laminates include at least one fluid-transmissible layer adjacent an upper or lower surface of a polymer-based core. Optionally, another fluid-transmissible layer is provided adjacent a lower surface of the polymer-based core to form geocomposite laminates having high permittivity and high transmissivity. The one or more fluid-transmissible layers are preferably geotextiles. Characteristic of the core element is high transmissivity, that is, a high rate of horizontal flow of gases or liquids through the core. Characteristic of the at least one fluid-transmissible layer is high permittivity, that is, a high rate of vertical transmission of liquids and gases through the geotextile layer and into the core element. Also characteristic of fluid-transmissible layers of the invention is high exclusivity with respect to solid materials. Core elements and fluid-transmissible layers advantageously can be formed separately so that the components may be separately transported to a site and installed in sequence, or bonded to one another onsite by welding or adhesives. The systems include further drain means teat communicate with the geocomposite structures of the system, such as perforated pipes and the like, which can connect further to culverts, ditches or waterways. The geocomposite structures and drain can form part of a greater subsurface geosynthetic system that provides reinforcement, separation, and drainage for the structure to thereby extend its useful life and decrease maintenance costs.

Patent CA-2343605-A1 (CA)
Title: Ecp manifold vent valve insert
Inventor: SICH GARY M
IPC: B60T15/02
Filed: 2001-04-04
Abstract: A vent valve insert comprises a bushing assembly, a piston assembly and a spring. It is designed to fit snugly and sealingly within a suitable borehole, such as the vent borehole of an ECP manifold assembly. The bushing assembly defines a longitudinal bore within which the piston assembly is situated. When pilot pressure is applied to its top surface, the piston assembly is forced to an open position wherein fluid is allowed to flow through the vent valve insert. Absent pilot pressure acting against the top surface, the spring acts to force the piston assembly upward within the longitudinal bore. Secured to the bottom portion of the piston assembly, an annular sealing member is carried upward so than its flat surface seats against: a raised inner portion of an annular valve seat. The vent valve insert is thus normally biased to the closed position. The vent valve insert also features a mechanism for preventing non-longitudinal movement of the piston assembly as it is moved longitudinally within the longitudinal bore. The mechanism not only guides the movement of the piston assembly within the bushing assembly but also prevents the bell clapper effect inherent to the vent valve inserts currently used in the industry.

Abstract: A dental fluoride rinse system comprising two different dental rinse compositions, typically maintained in separate vessels until the time that they are mixed with an appropriate solvent such as water. The first dental composition provides a non-stannous fluoride ion source and a phosphate ion source that has a pH of about 3.75 +  or - 0.75 when mixed with water and comprises greater than about 1% by weight of the fluoride ion. The second dry composition provides between about 0.1% and 1% stannous fluoride when mixed with the solvent and is administered to the patient after the first rinse composition so that the patient gets two different kinds of fluoride administered to the oral cavity in a short time period. In a significant advantage of the present system, the stannous fluoride can be mixed with water by the user.

Patent CA-2354769-A1 (CA)
Title: Syringe pumps
Inventor: TRIBE ROBERT JAMES
IPC: A61M5/145
Filed: 2001-08-07
Abstract: Conventional syringe pumps have a motor rotating a leadscrew, which drives a plunger head retainer to push a plunger along the barrel of a syringe so as to dispense medication to a patient. A force sensor in the head retainer measures the force on the plunger to detect when there is an occlusion restricting flow of medication and sounds an alarm. In the present invention, the motor is reversed to reduce the force to about 10% of that at which the occlusion is detected. The occlusion can be removed with a reduced risk of a bolus of medication being dispensed after which the user restarts the pump so that the plunger is driven normally.
