Abstract: A sputtering deposition wherein high aspect ratio apertures are coated with conductive films exhibiting low bulk resistivity, low impurity concentrations, and regular morphologies. A collimator is used having an aspect ratio that approximates the aspect ratio of the apertures. The resulting film thickness at the bottom of the aperture is at least 2X what can be achieved using conventional sputtering methods. The amount of material deposited at the bottom of the apertures can be further enhanced by elevating the temperature of the substrate (e.g. 450 o C) during the deposition process.

Abstract: A process for sealing the rotor (2) of a turbine (1) which uses wet geothermal steam under pressure in which the said rotor (2) is provided with a plurality of adjacent labyrinth sealing rings (A, B, C, D, E, F, G, H, I) interposed with passages (12, 13, 14, 15) which extend radially of the rotor itself. The process provides at least one stage in which a flow of steam is introduced into one of the said radial passages (13) and made to pass through the labyrinth of at least one of the said sealing rings (B), being throttled with a drop in pressure and reduction in temperature. The portion of steam which has been throttled is collected through another (12) of the said radial passages and exhausted or recycled to the turbine at an intermediate stage (IV) having the same pressure as the steam. The pressure and temperature values reached by the steam after throttling are such as to maintain it in a wet state. In this way, as the steam always stays wet, the salts in the original geothermal steam remain dissolved and are not deposited, thus allowing the seals to operate correctly.

Title: Aquarium filter assembly.
Inventor: WOLTMAN KLAUS
IPC: A01K63/04
Filed: 1992-06-02
Abstract: An aquarium filter assembly which can be utilized as a diatomaceous earth filter which is self-priming. The filter includes a housing having a pump means from which depends a filtering element. The water pumped through the filtering element can be directed either back into the housing for recirculation of the water in the housing, or out of the housing and back into the aquarium tank for filtering of the aquarium tank water. A valve within the housing operates to permit water entry into the housing upon initial insertion and during filtration of the aquarium tank water. The valve closes when the water flow from the filtering element is directed back into the housing. Diatomaceous earth can be added into the housing and the water recirculated within the housing serves to self-prime the filter element. After charging the filter element, the water flow from the filtering element is directed into the aquarium tank and the valve opens to permit regular filtering of the aquarium tank water.
