摘要： An isolated detector for gas is set forth and incorporates a closed source chamber in cooperation with a sample chamber through which sample gas flows. Gas within the source chamber comprises Krypton which is excited to a metastable state by a pulsed, high voltage, direct current spark. Subsequent decay of metastable argon emits ionizing radiation which passes through a membrane window into the sample chamber thereby ionizing selected constituents within the sample gas. Charged particles resulting from the ionization of selected constituents are collected with voltage biased electrodes in the sample chamber, and the magnitude of the resulting current flow is related to the concentration of the ionized molecules or compounds. The apparatus for generating ionizing radiation requires no external source of gas, is rugged, is relatively inexpensive to manufacture and operate, and exhibits an operating life much longer than source lamps used in prior art devices. The preferred embodiment of the invention is directed to the quantitative measure of impurities or pollutants in air samples.

摘要： A method and apparatus for detection of monoalkylhalides is disclosed. This apparatus contemplates detection of extremely small traces of monoalkylhalides through the nucleophilic substitution of a heavier halogen (preferably iodine) by introducing a sample gas having a monoalkylhalide therein in trace concentrations to be detected and passing it through a closed container providing a surplus of heavier halide ions. An exemplary source of a heavier halide is a container having an alkali iodide therein heated to a temperature sufficiently elevated to initiate iodine disassociation, such as 250.degree. C. An exchange of an iodine for a covalently bound fluorine or chlorine atom is achieved. The monoalkylhalide then has a larger molecular diameter and more complex electronic structure than that originally provided. It also has an enhanced affinity for slow or low energy electrons. This enhances the operation of detection equipment exemplified by an electron capture detector. The sample is passed through a column for separation of other gases and removal of any free iodide and is then passed to a detector. The invention is able to analyze alkenyl halides, however, some halides such as vicinal halides (particularly vinyl chloride) may require hydrogenation prior to transhalogenation.

摘要： A syringe which disperses medicate across a zone in the body during apparent conventional operation. The improved syringe includes a barrel, a plunger, and an operating cylinder. In operation, the needle of the syringe is inserted into the body at the distal portion of the portion of the body which is to receive the medicate. A single arm is attached to the barrel and passes through an operating cylinder with a thumb rest on its top. As a result, in operation, the user draws the single arm up to the thumb rest, thus causing the syringe to withdraw during injection and leaving a patch of medicate during operation.

摘要： A device for introduction of an ammonia dopant into a spectrometry system without the use of a delivery system containing ammonia. The delivery device includes an ammonium solid that will, upon the introduction of heat, yield ammonia gas for delivery into the spectrometer system. Use of such an alternative to traditional ammonia dopant systems will yield little or no change in spectrometer readings. The volumetric flow rate of the ammonium is controlled by the use of capillary tubes as the exiting pathway, where the flowrate is determined by the cross sectional area and length of the capillary tube. Delivery of the ammonia is aided by use of a frit or screen to permit only gas to exit.

摘要： A detection system measures very small concentrations of compounds of interest within gaseous samples. A spark discharge system induces pulsed spark discharges across a pair of electrodes within an inert gas in a gas flow chamber. Various reactions are induced by spark interaction with the flow of inert gas, and with any sample or dopant commingled with the inert gas, in the region of the pulsed spark discharge. This induces photon ionization which creates an instantaneous current flow within the gas flow chamber. Current flow is held constant for all concentrations of sample introduced into the gas flow by means of a control feedback system. The output of the control feedback system is indicative of sample concentration. The system responds linearly over approximately five orders of magnitude of sample concentration for use with the sample which will be described and low femtogram sensitivity is achieved.

摘要： A pulsed rare gas photoionization detector apparatus is set forth and incorporates a closed chamber for receiving a carrier gas flowing there through between inlets and outlets, and the carrier gas is exposed to a pair of electrodes forming a spark across the chamber and through the carrier gas. One component of the carrier gas is a dopant which selected from a plurality of rare gases. The sample to be analyzed is injected into the closed chamber where it commingles with the carrier gas. One reaction involves the formation of selected dopant in an excited state, which upon decay, serves as a source of ionizing radiation which reacts with sample compounds producing detectable events. These events are used to identify and quantify unknown compounds contained in the sample. The methods and apparatus are especially useful in selectively ionizing the compounds to be measured while not ionizing other constituents of the sample. This greatly enhances the signal-to-noise ratio for detecting impurity compounds. As an example, when the detection system is used to monitor air quality, the major constituents of air are not ionized.

摘要： The present apparatus in the preferred and illustrated embodiment comprises first and second rings which are respectively affixed to the mouthpiece and mouth pipe. As force is increased by the musician in holding the mouthpiece against his lips, such force is measured by cooperative measuring means fixed to said first and second means. In the preferred embodiment, the force measuring means includes an aligned pin on one of said means positioned relative to a transducer coil to thereby provide an indication of force. The signal indicative of force is delivered to a time based recorder and is recorded as a function of time along with additional data including sound intensity levels and frequency of the music to provide correlation between force, intensity and frequency as a function of time. A method is also taught including the recording of such data to teach the musician to reduce the force applied against his lips.

摘要： This disclosure sets forth a variable tensioning system for use in a valve featuring shear seals. In the preferred and illustrated embodiment, a spring system provides loading on the valve element to force that element into engagement with a valve seat. A sliding sealing surface is accomplished in this contact. The valve element may be a tapered plug, a sphere or a flat face or plate. Typically, it is a hard member working against a seat supporting a seal surface featuring a sliding shear seal. A specific minimum load is applied to the valve element to accomplish sealing against minimum pressure. The present apparatus incorporates a closed chamber enclosing a slideable piston. The piston has a specific cross-sectional area exposed to fluid pressure of the fluid being controlled by the valve. The piston applies pressure dependent force against the valve element. This adds to the force applied to the valve element by a spring means, the two forces controllably adding to assure that the seal is sufficiently loaded to perfect a seal up to a specified maximum pressure.
