摘要:
A method and apparatus for desorbing processing liquid from a processing liquid delivery line is provided. Non-thermal energy, such as ultrasonic energy or electromagnetic energy, is applied to a processing liquid delivery line. The non-thermal energy may be applied directly to the processing liquid delivery line, or may be applied indirectly via a conducting medium which distributes the energy along the length of the processing liquid delivery line. When non-thermal energy in the form of electromagnetic energy is employed, the frequency of the electromagnetic energy is adjusted to match the vibrational frequency of the absorbed molecules of processing liquid.

An electrochemical cell sensing circuit for an electrochemical cell having a working electrode, a counter electrode and a reference electrode in an electrolyte, which in use, when a gas to be analysed is introduced into the cell, generating a current between the counter electrode and the working electrode, and a potential at a position in the electrolyte is sensed by the reference electrode. The circuit comprising power supply means (12, 13, 14, 15, 16, R4, R5, D1) for applying an offset voltage to the counter electrode (c) relative to the working electrode (w), an amplifier means (A3, A5) for monitoring the voltage difference between the reference electrode (r) and the working electrode (w) and operable in use to feed back a current to the working electrode (w) through a feed back loop, and thereby tend to maintain the working electrode (w) at substantially the same potential as the reference electrode (r), the circuit includes measuring means (15, 16, 17, S1, R3, C2, A3) for measuring the current feed back by the amplifier (A2, A3) to the working electrode (w) as a measure of the cell current flowing between the working electrode (w) and the counter electrode (c).

Differences in the physical and chemical properties of synovial fluid from healthy and arthritic joints are detected by infrared spectroscopy. A beam of infrared light is directed at a sample of synovial fluid (either in its native form or prepared as a film) and changes in the physical and chemical properties of the fluid being analyzed are detected at one or more wavelengths to determine whether changes in the position, width, absolute intensity, relative intensity or shape of the infrared absorption have occurred which are characteristic of the arthritic condition.
摘要:
A finger guide (2) comprises first and second orthogonally-oriented portions (4,12) each comprising a pair of opposed converging surfaces (6,8;14,16) into which the end and the shank, respectively, of a finger for examination fit. Because of the relative orientation of the surfaces, movement of the finger relative to an examination surface (22) is reproducibly constrained.

The invention is a gap accessary device for elevated roller rails disposed on a platform floor. The device includes a housing, fingers, tangs, roller support structures, rollers, a first curved truncated inclined plane, and a second curved truncated inclined plane. The device allows cargo to enter a platform without catching on the platform threshold and requires less effort to load cargo onto a platform with elevated roller rails.

Methods of forming a strained channel device utilizing dislocations disposed in source/drain structures are described. Those methods and structures may include forming a thin silicon germanium material in a source/drain opening of a device comprising silicon, wherein multiple dislocations are formed in the silicon germanium material. A source/drain material may be formed on the thin silicon germanium material, wherein the dislocations induce a tensile strain in a channel region of the device.

Embodiments of the present invention are directed to a devices and methods for forming a desired miture of two or more fluids in a conduit. The devices and methods feature control means having error monitoring means and in response to an error event the control means organizes the packet-group of command signals to form at least one first error packet group. The error event occurs during the period of time in which the at least one error packet-group is received by a selectable value. The at least one error packet-group comprising an order or timing of first command signals and second commands signals to minimize deviation from the desired mixture in the flow of mixture-packets forming the desired mixture of two or more fluids in a conduit during the error event.
