摘要:
A method for vaporizing organic materials onto a substrate surface to form a film including providing a quantity of organic material into a vaporization apparatus and actively maintaining the organic material in a first heating region in the vaporization apparatus to be below the vaporization temperature. The method also includes heating a second heating region of the vaporization apparatus above the vaporization temperature of the organic material and metering, at a controlled rate, organic material from the first heating region into the second heating region so that a thin cross section of the organic material is heated at a desired rate-dependent vaporization temperature, whereby organic material vaporizes and forms a film on the substrate surface.

A liquid proportioning system controls the mixing of water and a fire retardant concentrate through the operation of a diaphragm operated valve. The diaphragm valve controls the flow rate of concentrate in response to the sensed pressure of water supplied to a proportioner, so that a predetermined proportion of concentrate and water is maintained.

摘要:
A method for controlling the deposition of vaporized organic material onto a substrate surface, includes providing a heating device to produce vaporized organic material; providing a manifold having at least one aperture through which vaporized organic material passes for deposition onto the substrate surface; providing a controller operating independently of the heating device and effective in a first condition for limiting the passage of vaporized organic material through the aperture, and effective in a second condition for facilitating the passage of vaporized organic material through the aperture; and wherein the heating device, or the controller, or both are contiguous to the manifold.
摘要:
Imaging systems, imaging device analysis systems, imaging device analysis methods, and light beam emission methods are described. According to one aspect, an imaging device analysis method includes receiving initial light comprising a plurality of wavelengths of light, filtering some of the wavelengths of the initial light forming a plurality of light beams comprising different wavelengths of light, after the filtering, optically communicating the light beams of the different wavelengths of light to an imaging device, receiving the light beams using the imaging device, and analyzing the imaging device using light, wherein the light beams comprising the different wavelengths of light are emitted beams after the receiving.
摘要:
A method for vaporizing organic materials and condensing them onto a surface to form a layer, comprising: providing a quantity of organic material in a powdered form in a first container; fluidizing the organic material in the first container and transferring such fluidized material to an auger structure; and rotating at least a portion of the auger structure to transfer fluidized powder from the first container along a feeding path to a vaporization zone where such powder is vaporized and delivered to the substrate to form the layer.
摘要:
Human osteogenic cells secrete biological activities that stimulate cancer cells to migrate to and/or invade tissues. Conditioned medium (CM) produced by human pre-osteoblasts and osteoblasts induced migration and tissue invasion of human prostate cancer cells. Thus, conditioned media and/or proteins isolated therefrom may be used to identify metastasis-inducing factors. Also described are methods of identifying an inhibitor of such factors.
摘要:
A flange valve to deter entry of rodents and pests, insertable on existing devices, comprising a unidirectional swinging door attached on an inner wall of a frame, the door and the inner wall of the frame having a clearance between them of a dimension not allowing entry of rodents and pests. The design of the frame is catered to the desire of the user and may be a laterally protruding ring having a central circular opening and openings along the edges for the insertion of bolts or screws; a laterally protruding ring on one peripheral edge of an open cylindrical body; a cap having a flat top with a central circular opening and openings for the insertion of bolts and screws; a conduit; or a wax free toilet bowl gasket, a toilet flange or a wax ring used in the installation of toilet bowls.
摘要:
A method used for rounding the corners of a pile of sheets. Air is injected between the sheets in the pile to create a lubricating fluid film between the sheets; at least one of the corners of the pile is placed in abutment against two reference surfaces formed facing at least one corner of the pile, and the four cutting devices corresponding to each corner are actuated.
