Abstract: The invention relates to a process for the production of lower olefins from methanol by reaction of a reaction mixture containing methanol and/or dimethyl ether vapour and water vapour in a tubular reactor over an indirectly cooled catalyst based on crystalline aluminosilicates of the pentasil type having an Si/Al atomic ratio of at least 10. The process is characterised in that in order to produce an olefin mixture containing at least 5% by weight of ethylene, at least 35% by weight of propylene and at most 30% by weight of butylene, relative to the entire hydrocarbons, the reaction is carried out at a total pressure of 10 to 90 kPa, at a weight ratio of water to methanol or to methanol equivalents of 0.1 to 1.5 at a temperature of the reactor cooling medium of 280 to 570 DEG C over a proton-containing catalyst of the pentasil type which has an alkali metal content of less than 380 ppm, a ZnO content of less than 0.1% by weight, a CdO content of less than 0.1% by weight, a BET surface area of 300 to 600 m<2>/g and a pore volume (measured by mercury porosimetry) of 0.3 to 0.8 cm<3>/g.

Abstract: A timing system (4) for controlling, by means of a single overhead camshaft (10), three adjacent, homologous valves (5,6) of an internal combustion engine cylinder; each valve having a tappet (12) located between the valve stem (13) and a respective control cam (11) on the camshaft. The tappets are arranged with their axes shifted laterally, and alternately on opposite sides, in relation to the respective valve stem axes, so as to define a first eccentricity (E1) between each valve stem and respective tappet in a plane perpendicular to the camshaft axis. In a plane perpendicular to the above plane, the intermediate valve stem is aligned with the axis of the respective tappet, while the other two valve stems are both shifted laterally in relation to the respective tappet axis and towards the intermediate valve stem, so as to define, with the respective tappets, a second eccentricity (E2) perpendicular to the first. The tappets may thus be arranged side by side and aligned centrally along the camshaft axis.

Abstract: A position-sensitive radiation detection system comprises a radiation-conducting rod (10) and two radiation detectors (21, 22) arranged at both ends of the rod. Radiation which is incident in the rod  via  an entrance window (11) is dispersed on a target plane, for example, by a diffusely reflecting facet (12) and guided towards the detectors while simultaneously being attenuated. Consequently, the relative intensity on each detector (21, 22) is dependent on the position of the point where the radiation beam (1) is incident on the target plane in the rod (10). Evaluation of the output signals (I₁, I₂) of the detectors in a processing unit (30) yields the position (X) of the incident radiation.

Abstract: A method for depositing a film of a desired material on a substrate comprises dissolving at least one reagent in a supercritical fluid comprising at least one solvent. Either the reagent is capable of reacting with or is a precursor of a compound capable of reacting with the solvent to form the desired product, or at least one additional reagent is included in the supercritical solution and is capable of reacting with or is a precursor of a compound capable of reacting with the first reagent or with a compound derived from the first reagent to form the desired material. The supercritical solution is expanded to produce a vapor or aerosol and a chemical reaction is induced in the vapor or aerosol so that a film of the desired material resulting from the chemical reaction is deposited on the substrate surface. In an alternate embodiment, the supercritical solution containing at least one reagent is expanded to produce a vapor or aerosol which is then mixed with a gas containing at least one additional reagent. A chemical reaction is induced in the resulting mixture so that a film of the desired material is deposited.

Title: Etching method for increased circuitized line width unitformity
Inventor: COVERT KATHLEEN L
IPC: C23F1/02
Filed: 1992-01-27
Abstract: Disclosed is a method of fabricating a microelectronic package, especially a microelectronic package having copper circuitization on a dielectric substrate. The method includes depositing copper on opposite surfaces of the package, and then depositing resist atop the copper. The resist is patterned, e.g., by photolithography or screening so that intended circuitization traces are covered by the resist. The exposed copper is etched, and the resist is stripped off of the unexposed copper. The process is characterized in that the etchant is upwardly sprayed onto a downwardly facing first surface of the package for half of the etching cycle, and then the package is rotated so that etchant is upwardly sprayed onto the downwardly facing second surface of the package.
