Patent EP-0236957-A3 (EP)
Title: A heating device, in particular for automatic samplers
IPC: G01N30/04
Filed: 1987-03-05
Abstract: A device for heating sample containing vials, in a gas-chromatographic apparatus provided with an automatic sampler, comprises a shroud in which a depression is made by a fan which sucks external air and conveys it under pressure into a Venturi tube shaped duct. This depression causes more external air to be sucked through separate openings of the shroud and to follow a different path along the resistors, the sampler, the tray and the vials and to be eventually exhausted through the vent together with air coming from the fun duct.

IPC: C10L5/04
Filed: 1987-06-12
Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung von Briketts 
mit guter Verlade-, Wetterstands- und 
Feuerstandsfestigkeit aus nicht backenden feinkörnigen Brennstoffen 
wie Anthrazit- oder Magerkohle, Feinkoks, Hartbraunkohle 
oder Holzkohle. Das Verfahren besteht darin, daß man den auf über 70°C 
erhitzten feinkörnigen Brennstoff mit einer wässrigen 
heißen Lösung eines vollverseiften Polyvinylalkohols bedüst, das 
Gemisch aus Brennstoff und Bindemittellösung homogenisiert 
und unter guter Entwrasung zu Briketts verpreßt. Dabei setzt man dem 
feinkörnigen Brennstoff vor der Behandlung mit der 
Bindemittelösung 5 bis 15 % einer pulverförmigen backenden Kohle zu. 
Die derart hergestellten Briketts werden den Forderungen 
des Umweltschutzes gerecht, da sie rauch- und rußfrei verbrennen und 
ihre Verbrennungsabgase frei von Schadstoffen sind.
Patent EP-0262582-A3 (EP)
Title: Method for determining the concentration ratio of lithium to sodium ions and apparatus for carrying out this method
IPC: G01N27/414
Filed: 1987-09-24
Abstract: The ratio of the concentration of lithium ions to sodium ions can be determined with high accuracy and reproducibility by immersing an electrode for determining lithium ions and an electrode for determining sodium ions in the sample solution, connecting the two electrodes electrically to each other via a voltmeter and determining the potential difference  DELTA V between the two electrodes. The ratio of the concentration of lithium ions to sodium ions can be calculated from this potential difference. It is also possible to connect the lithium electrodes and sodium electrodes electrically via a voltmeter to a single external reference electrode or a common electrode and to calculate the potential difference  DELTA V from the two potential differences measured. 
<??>The method makes it possible to precisely determine the concentration ratio of lithium ions to sodium ions in the presence of high and varying concentrations of sodium ions, for example in blood serum, when the sodium concentration is about a hundred times greater than the lithium concentration. Miniaturised apparatuses for performing the method, for example flow-type electrodes, so-called wire electrodes or arrangements based on the planar technique make possible a rapid determination of the concentration ratio in the clinical field.

Title: Microwave frequency synthesizer with a frequency offset generator
IPC: H03L7/10
Filed: 1989-11-06
Abstract: A phase lock/frequency control loop includes a voltage-­
controlled oscillator (10) operating within a predetermined 
microwave frequency band and phase-locked to a reference oscillator 
(24) operating at a reference frequency below microwave frequencies. 
An offset loop signal is developed by an offset mixer (12) 
heterodyning the voltage-controlled oscillator (10) output signal 
with an offset microwave signal from an offset generator (14) whose 
frequency is located at the center of the predetermined microwave 
frequency band of the voltage controlled oscillator (10) to form a 
signal at an intermediate frequency (I.F.) within the frequency 
range of a programmable digital frequency divider (20). A 
phase/frequency detector (26) produces an error signal having a 
magnitude representative of the difference between the output from 
the divider (20) and a reference signal from a reference oscillator 
(24). The polarities of the error signal supplied, through an 
amplifier (30) and filter (32) to the voltage controlled oscillator 
(10) are set in accordance with whether the frequency commanded by a 
decoder (22) controlling the divider (20) is above or below the 
offset frequency. The signal frequency offset technique increases 
the frequency range of the indirect frequency synthesizer to twice 
the highest operating frequency of the programmable digital 
frequency divider.

Title: Fet monolithic microwave integrated circuit variable attenuator
IPC: H01P1/22
Filed: 1990-03-28
Abstract: A MMIC variable attenuator uses depletion mode 
Schottky gate FETS as variable conductance devices in a "π" 
configuration to vary attenuation as a function of a DC 
control voltage. Attenuation is flat within ± 1dB, VSWR is 
≦ 2:1 throughout the operating frequency and control voltage 
range, and about 12 dB variable attenuation is provided. 
The "π" is formed by FETs (100, 200) in shunt to ground between 
attenuator input and output, and by a FET (300) in series between 
input and output. Resistors and an inductor means (600) connected in 
parallel with the series FET (300) extend attenuator bandwidth to 
20 GHZ and improve attenuation linearity versus control 
voltage. A resistor in series with each 
shunt FET (respectively also 615 and 630) 
improves linearity. The typically 0 to +3 VDC control 
voltage is applied to the FET gates and drain/source leads 
permitting attenuation control with a single control 
voltage (Vc). RF power capability is increased without degrading 
RF performance by using multi-gate FETs wherein the ratio of 
gate width to number of gates is maintained substantially 
constant compared to a single-gate FET. Series-connected 
FETs further increase attenuator RF power capability. 
Operating from 2-20 GHz, embodiments using a single control 
voltage handle about 30 mW RF input power and use single-­
gate and dual-gate FETs, and handle about 250 mW RF input 
power and use triple-gate FETs. A third embodiment, 
operating from DC-20 GHz and handling about 500 mW RF input 
power, employs dual-gate FETs throughout and requires two 
complementary control voltages (Vc and Vc').
