A method for drying a ceramic article comprises providing microwave radiation from a microwave generating source, providing a ceramic honeycomb structure having a middle portion and at least one end, and exposing the ceramic honeycomb structure to the microwave radiation while shielding the at least one end from directly receiving the microwave radiation, such that the radiation absorbed by the middle portion is equal to or greater than the radiation absorbed by the at least one end, and the proper drying of the entire honeycomb structure without heat-induced structural degradation is thus ensured.

Cassette (50) performs assays, e.g. multiplexed protein biomarker assays. Wide, bubble-free, slow flows are produced from liquids stored on cassette (50), flowing over wide array (20) of ligand receptors on a capture surface. Flows of Reynolds Number less than about 1, preferably 1×10−1 to 5×10−3, are heated in region (34) preceding and including bubble removal system (128). Analyte is introduced through compressed septum (32). External actuations of displacement pumps (30, 37) and valves (137 A, B, and C) produce flows in response to flow-front optical sensors (150, 152). Elastic sheet provides pump and valve diaphragms and resilient expansion of mixing volume (131). Break-away cover portions are pistons. Heating is by conduction through cassette from external contact heater. Planar cassette body, when tilted from horizontal, enables upward flow from pumped storage (134, 135) to reaction (133) to waste (139), with buoyancy bubble removal before reaction. Reading of fluorescence is by external reader, employing calibration, control and reference features on capture surface. Extensive set of calibration features of differing intensities enables self-calibration.

Methods and apparatus for plugging cells of honeycomb structures are disclosed. A first method covers the honeycomb structure's end face with a mask having a body and plurality of sized openings positioned to oppose certain cell channels, wherein the outer edge of the body extends radially outwardly from the end face. A film also extends outwardly of the end face, and a plug of material is provided upon the film. The mask and film material are sealed to one another, and a force is applied to the film forcing the material through the mask and into the cells. Also disclosed is adhering a mask to a first end face of the honeycomb structure such that the mask has an outer portion that extends radially beyond an outer edge of the honeycomb; providing a volume of plugging material; clamping the outer portion between a first clamping portion and a second clamping portion; and transferring the plugging material into the honeycomb. Also disclosed are methods and apparatus for cutting the plugging material between the mask and a pre-plugging chamber to form a substantially planar surface thereon.

A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth / key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.

The present invention is a method of separating recombinant human serum albumin (rHSA) from low molecular weight contaminants in a liquid, which method comprises the steps of: (a) providing a separation medium, which includes anion-exchanging ligands coupled to a base matrix; and (b) contacting the liquid with the separation medium to adsorb the rHSA to the ligands. In one embodiment, the functional groups of the ligands are weak anion-exchanging groups, preferably secondary amines, and the density of ligands on the base matrix is relatively high.

An inspection system formed at least from an inspection system housing including at least one internal chamber that supports an extendible camera support shaft extending distally through a pilot nozzle port into a combustor of a gas turbine engine is disclosed. The inspection system may include a camera capable of capturing high quality images together with position coordinates. Thus, the inspection system enables images in a combustor of a gas turbine engine to be captured and recaptured at a subsequent outage so that the images may be analyzed and compared for preventive maintenance, troubleshooting, and the like. The inspection system may include three degrees of freedom for the camera mounted on the extendible camera support shaft.

A system and method for image-guided instrument calibration includes a robotic unit coupled to the instrument, an imaging unit, and a first control unit coupled to the robotic unit and coupled to the imaging unit. The control unit receives imaging data related to the target and the instrument from the imaging unit, and controls the robot unit to correctly orient the instrument for insertion based on the imaging data.

The present invention relates to a method for preparing a Cannabis plant Δ9-tetrahydrocannabinol isolate from a crude solvent extract of Cannabis plant material. The invention relates further to a Cannabis plant THC isolate comprising Δ9-tetrahydrocannabinol, Cannabinol (CBN) and / or Cannabidiol (CBD) and to a pharmaceutical composition comprising the Cannabis plant THC isolate.
