Abstract: A standardized collector surface (3), with appropriate selective absorption, is contacted in well-determined conditions with the gas, the liquid or the solid in order to sample, concentrate and optionally effect a well-determined chemical reaction of the trace element to be measured. The collector surface is then taken to a contact membrane (1) heated and swept by a carrier gas (2) from the receiver head of an analysis apparatus in order to obtain the analysis of the absorbed gas and/or of the reaction product thereof. The trace elements quantatively thermally desorbed by the collector surface (3) are put in a solution, are subjected to a diffusion and an evaporation by traversing the contact membrane (1) and are carried away by the carrier gas (2) through a sampling conduit or a fractionating column by gas-chromatography towards a gas analyser, for example a mass spectrometer (MS). The sampling method for analyzing qualitative and quantitative traces by means of gas-chromatography (GC) and the combination of MS/GC, is simple, very fast and universal. This method is appropriately used for routine work in analyzing the environement, residues, food materials, quality controls, medical and chemical analysis, toxicology, microbiology, research on guinea pigs, pharmacology, doping control, criminalistics, and forensic medicin.

Granted: 1989-11-29
Abstract: The separating efficiency of a cyclone separator used for removing solid particles from a gas stream (for example ash particles from the combustion gas which is passed to a gas turbine) is increased by retarding the particles before they arrive at the cyclone and thereafter accelerating them over a short distance before they enter the cyclone. In this way large particles will have a lower speed than small particles when entering the cyclone. Despite a high velocity of the transport gas and a high inlet velocity for small particles, it is possible to obtain an inlet velocity for larger particles which is desirably low from the point of view of reducing erosion of the cyclone separator. The separation of fine particles is improved. The retardation of the particles may take place in a T-shaped branch pipe, which has one branch connected to the cyclone, a second branch connected to a conveying pipe and a third branch which is formed as a blind space.

Title: Test period generator for automatic test equipment
IPC: H03K5/13
Filed: 1984-08-01
Granted: 1988-03-30
Abstract: A timing subsystem 10 including several test period generators for supplying a variety of timing signals to a device under test. Major, minor, and free-run period generators each supply various timing signals to a multiplexer 18, which selectively connects the timing signals to timing generators 20. A central processing unit 28 supplies data to the period generators and timing generators to define their respective timing signals. Timing signals generated by the major period generator 12 define the overall testing rate. The minor period generator 14 generates multiple timing signals within the periods of the major clock signals to permit higher clock rates. Timing signals that are independent of the major clock periods are generated by the free-run period generator 16. An external synchronizer circuit 26 provides a feedback loop from the device under test 22 to the major period generator. A reference driver trigger delay circuit 27 provides means for calibrating the timing generators. Each of the three period generators includes two interconnected timing interval generators 30 and 40 that alternately generate overlapping timing signals. Each timing interval generator includes a stop-restart oscillator 32, a counter 34, and a delay-line vernier 36. Upon the receipt of a start signal, the oscillator stops and restarts to align its clock pulses to the start signal. The oscillator output clocks the counter, which supplies a signal to the vernier when a preselected number is reached. The vernier delays the counter signal by a preselected delay and issus a signal that designates the end of the period.

Abstract: The invention relates to a resistor element assembly for a glass sheet heating furnace and to a method of replacing a resistor element. A resistor element is built by placing successively in longitudinal direction ceramic elements, with a resistance wire wound therearound. Between the ceramic elements are fitted ceramic spacer blocks whose diameter exceeds that of the resistance wire coils. The resistor element is carried by a support frame upon the spacer blocks. A problem to be resolved is to provide a long resistor element, wherein the major variations in length between the components of various materials caused by major temperature variations do not produce deformations in resistance wires. This problem has been resolved by fitting between one end of the support frame and the corresponding end of the resistor element a tensioned spring which compresses the resistor element at all operating temperatures against a limit stop at the other end of the support frame. The resistor element can be replaced by releasing said spring from the support frame and by pulling the resistor element out of a furnace by utilizing a core pin extending through the entire resistor element, whereby the ceramic elements remain subjected to compression stress. By using an auxiliary spring between the end of said core pin and the end of said resistor element, the compression holding the resistor element together can be maintained also during transportation and installation.
