Abstract: The invention relates to a method of estimating plasma cholesterol levels using small samples of blood and in particular to estimating levels of low-density lipoprotein in capillary blood. The method comprises providing a surface to which a sample of blood is applied, the surface carrying, either over a part or over its whole, anionic groups which have an affinity for low-density lipoprotein. The low-density lipoprotein in the applied blood sample binds to the surface and is subsequently measured by methods which detect either the protein component or the lipid component of the bound low-density lipoprotein.

Abstract: An audio noise gate has a main audio circuit (30) including a filter with a control terminal (32) for determining frequency response and having at least two different roll-off frequencies including one that rolls-off high end content audio signals and one that passes high end content audio signals. The main (30) is controlled from two secondary circuits one including a high pass filter for determining high frequency content of the audio signal and the other comprising a signal detection circuit (60) including a peak detector for determining absence or presence of a note. The signal detection circuit 60 operates in combination with the high pass filter circuit to provide for automatic adjustment of the noise gate to control the release time, quickly for short notes and slowly for held notes. The output of the high pass filter circuit (50) also includes a peak detector and a gain stage for controlling the frequencing response of the main circuit.

Abstract: Placed on a tank body (1) is a cover (6), the plane dividing these two parts extending obliquely to the horizontal. Arranged in a rhomboid opening (8) in the cover (6) is a push-button (11), to which a lever (13) is rigidly attached. The latter reaches with its one end into an eye (24) of the valve pipe (23). The push-button (11) is pivotably mounted on the tank body (1) and can be actuated even without the cover (6) in order to examine the functioning of the interior fittings. The pivot axis (26, 27) of the push-button (11) divides the latter, seen from above, into two approximately equal parts, pressure on one part triggering the flushing operation and pressure on the other part immediately interrupting the flushing. The push-button (11) can be fitted very easily without tools and can be removed just as easily for repair. <IMAGE>

Abstract: An optical fiber (F) and a laser (L) are fixed on the top faces of two bases (EF, EL) which also have two facing vertical faces. A spring (4) presses these two faces against each other so as to create thrust friction. The thrust force is initially moderate in order to enable the relative vertical and transverse positions (GV, GT) of the two bases to be adjusted smoothly, after which the force is increased progressively in order to prevent relative displacement taking place while the two bases are being welded together by means of a YAG laser. The invention is particularly applicable to making optical transmission heads usable in optical fiber telecommuncations systems.

Abstract: A feed-back control system for a combustion engine having spontaneous ignition is described. The feed-back control system comprises sensors for detecting operating variables, an electronic control device and an actuator for influencing the mass of fuel to be fed to the internal combustion engine. In a first step, a fundamental value (ME) for the fuel mass is calculated as a function at least of the engine speed and position of the accelerator pedal. This fundamental value for the quantity of fuel is corrected in a second step, the correction being effected as a function of the exhaust gas temperature signal. The exhaust gas temperature signal used for the correction is calculated from the measured exhaust gas temperature signal and further operating variables. <IMAGE>

Abstract: A multilevel resist process for fine line e-beam lithography, or, alternatively, deep ultraviolet (DUV) optical lithography with a clear field mask involving the use of a plated transfer layer for image reversal. The process preferably uses a high brightness, quarter-micron diameter electron beam and a high speed negative resist to fabricate microwave MESFETs, MODFETS, and integrated circuits with gate lengths of 0.25 micron and below. This is achieved by producing a line of negative resist which can be developed to 0.25 micron or below. A plated transfer layer is then applied which provides image reversal, converting the line of resist into an opening suitable for conventional gate recess etching, gate metal deposition, and lift-off. A positive resist can be substituted for the negative e-­beam resist and exposed with DUV through a clear field mask instead of an electron beam for the fabrication of MESFETs.

Abstract: Method, system and apparatus for metering fuel to an internal combustion engine via a carburetor (20) having a mixture conduit with a venturi (42) therein. A main fuel nozzle (70) supplies fuel to the venturi of the carburetor in response to the static pressure drop induced across an associated main fuel flow controlling restriction (36) by the engine intake induced air flow through the carburetor mixture conduit. A pitot tube (80) is disposed in the venturi with an opening (82) facing upstream in a zone of maximum air flow through the carburetor venturi. A vent passageway (82-100) system connects the pitot tube to a single closed air chamber (62) cooperable with either a diaphragm (60) or a float to regulate operation of an inlet valve (58) controlling flow of fuel to a main fuel controlling restriction. The adverse effect of engine intake induced tuning pressure wave forms in the mixture conduit of the carburetor transitting the venturi is eliminated, reduced or modulated by the dynamic pressure exerted by said tuning waves at the pitot tube and transmitted by the vent passageway to said chamber and to said main fuel restriction.
