Patent NL-7803711-A (NL)
IPC: H01L21/205
Filed: 1978-04-07
Abstract: A process for epitaxially forming a layer of gallium arsenide having a first conductivity on a substrate of gallium arsenide having a second conductivity in an enclosure having an inner liner comprised of a silicon compound, comprising decomposing arsine to form arsenic; chemically reacting a first quantity of hydrogen chloride and gallium to form gallium chloride, the gallium chloride reacting with the arsenic to form gallium arsenide on the substrate, a portion of the first quantity of hydrogen chloride remaining unreacted and tending to cause silicon contaminants from the liner to be deposited on the substrate; and providing a second quantity of hydrogen chloride into the enclosure which serves to initially etch, and hence clean, the outer surface of the substrate prior to the formation of gallium arsenide thereon, and simultaneously tends to inhibit the formation of silicon contaminants on the substrate, the second quantity and the first quantity having a preselected ratio such that the growth rate of the gallium arsenide layer on the substrate is greater than the etching rate of gallium arsenide due to the second quantity of hydrogen.

Patent NL-8105381-A (NL)
IPC: A61B5/02
Filed: 1981-11-27
Abstract: A method and a device for correcting the cuff pressure in the indirect, non-invasive and continuous measurement of the blood pressure in a part of the body by using a plethysmograph in a fluid-filled pressure cuff, an electronic control circuit, and an electric pressure valve. The cuff pressure is controlled by the plethysmographic signal in closed-loop operation with the aid of a servo-reference level obtained via a memory circuit. The servo-reference level, in operation of the device, is adjusted by opening the closed loop of the control circuit for a short interval, after which, in open-loop operation the cuff pressure is adjusted at an intermediate pressure derived from the pressure last measured and the servo-reference level is adjusted via the memory circuit.

Title: Cooling tubes and fins for aluminium heat exchanger - uses assemblies of tapered rings to locate fins on tubes of exchanger used particularly in refrigeration
IPC: B21D53/08
Filed: 1983-09-27
Abstract: The fixing of the fluid carrying tubes to the cooling fins is complicated in aluminium heat exchanger by the difficulty of welding aluminium and the ease with which aluminium may be damaged by excessive force if mechanical fixing is used. Difficulties of mechanical assembly are overcome by use of split sleeves with an exterior taper, one for each contact between the tube and cooling fin. Matching rings have an internal taper. The two are pressed together by a pressure plate and a push rod, with an elastic buffer between the plate and the interior tapered ring. The pressure plate is positioned by a spherical seat.

Patent NL-8700125-A (NL)
IPC: H04L25/03
Filed: 1987-01-20
Abstract: An arrangement for combatting intersymbol interference and noise introduced into a data signal transmitted at a symbol rate 1/T by a transmission channel having a memory span LT corresponding to a number of L consecutive data symbols, comprises a receive filter (RF), a first decision circuit (ID) for forming preliminary symbol decisions in response to the transmitted data signal, a second decision circuit (FD) for forming final symbol decisions, means (FFS and FBS) for compensating pre- and post-cursive intersymbol interference, and a combining circuit (AD) for forming the input signal for the second decision circuit (FD). By selecting in these compensating means the memory span MT of the feedforward section (FFS), and possibly also the memory span NT of the feedback section (FBS), to be smaller than the memory span LT of the transmission channel, a simplification of the implementation of the arrangement is achieved, whereas the attainable transmission quality does not appreciably differ from the transmission quality attainable with MT=NT=LT.

Title: Method for synthesis of concentrated aqueous solution of hydrogen peroxide by solar energy
Inventor: MILETIEV ROSEN G
IPC: C01B15/027
Filed: 1999-05-21
Abstract: The method is materialized with cheap catalysts such as chlorophyll and superoxydimutase due to the chance of being directly produced from vegetative and animal organisms, cheap chemicals - CaCl2, NH3 and CO2, and solar energy for the synthesis of hydrogen peroxide (H2)2). It is highly ecological enabling the production of highly concentrated H2O2 solution of water and atmospheric oxygen. According to the method aqueous solution of chlorophyll is used which absorbs the electromagnetic solar energy, is converted to active state and forms chemical reaction with the oxidation-reduction system which in the different alternatives of execution can be single- or multi-component. To eliminate the free radical formed in the system an immobilized enzyme - superoxydimutase is introduced. The produced H2O2 is separated from the synthesis medium by reverse osmosis which is favoured by the high molecular weight 0f the substances used. The separated H2O2 is concentrated in a reactor in two stages: chemical (from 1-2% to 20-21%) and a rectification (from 20-21% to 80-90%). The first stage is made by means of a chemical cycle realized by the use of CaCl2, NH3 and CO2, and the second stage by the use of a rectification column. 4 claims, 1 figure
