Abstract: The invention relates to a device, esepcially for stabili­zing soil material, comprising a substantially elongated web (l) which in mounted position on a support (4) forms a plurality of cells or pockets. For the purpose of providing a device which can be manufactured from inexpensive raw ma­terial, which possibly can easily decompose, and which can be manufactured in accordance with a simple and preferably known process, and at the same time render a minimum tran­sport volume, and which in connection with soil stabilizing provides favourable anchoring in the ground which is to be soil stabilized, and which forms pockets or cells having walls extending vertically independent of the slope angle of the ground for stabilizing the soil even during heavy rain, it is according to the invention suggested that the web (l) is constituted by an initially relatively thin, substantially flat web (l), preferably of flexible plas­tics, which in a first direction is provided with rows of consecutively arranged slits (2,2a, 2b) which are so stag­gerd relative to each other that the web (l) by the stret­ching thereof in a second direction forms oppositely undu­lating strips (3a,3b,3c) which upon mounting of the web on a more or less inclined hill define side by side arranged cells or pockets (8) which can be filled with soil (9) be­ing stabilized by the device. Due to the sharp lower edges (l0) of the undulating strips (3a,3b,3c) the device (l) in stretched condition will easily be pressed down into the ground (4) for the anchoring thereof in the ground (4), and the various degrees of stretching can be harmonized to the various angles of inclination of the ground on which the device is to be carried.

Abstract: A multifunctional member and reflector lamp employing same for mounting a light-source capsule on the inside of the neck of the outer envelope, for optically aligning the capsule with respect to the reflector, for reflecting heat away from the base region of the lamp, for blocking convective heat transfer into the lamp neck, and for reflecting light incident on the member toward the lens. In performing these multiple functions, the member reflects heat back to the filament or light source which improves its efficiency, and the member redirects light toward the lens which improves the efficacy of the lamp. In a preferred embodiment, the multifunctional member is formed from stainless steel and has a bowl-shaped body with a somewhat flexible peripheral annular tab extending upward and outward conically. The peripheral tab may be crimped, slotted, or have a tapered thickness in order to provide flexibility sufficient for mounting. The bowl-shaped body preferably is paraboloidal having a focal center substantially coincident with the focal center of the reflector. In an alternate embodiment, the multifunctional member has a curvature matched to the curvature of the reflector and no peripheral tab s that the reflector has been optically extended to the press seal of the light-source capsule. A lamp constructed in accordance with the invention is particularly well suited for employing a heat-sensitive component, such as a diode, in the base region of the lamp..

Abstract: A method of reproducing sub-micron images in a first imaging layer (10). A second imaging layer (30) is deposited on an etch-stop film (20) formed on the first layer, and the second imaging layer is exposed to an E-beam at low dose. The resulting standing wave exposure pattern (35) is converted into a corresponding topology pattern having peaks and valleys by exposure to a wet developer. Ions are implanted through the second imaging layer into portions of the first imaging layer below the valley portions of the standing wave topology pattern. The second imaging layer is removed without appreciably attacking the etch-stop layer, and then the etch stop layer is removed without appreciably attacking the first imaging layer. The first imaging layer is anisotropically etched in an O₂ RIE, the implanted regions serving as an etch mask. The process results in the formation of small images at high throughput.

Abstract: A device for controlling the expansion valve (5) of a refrigerating appliance in a motor vehicle is described. A first temperature sensor (22) measures in a first place the temperature (T3) of the refrigerant in the direction of flow behind the evaporator (10); a second temperature sensor (20) measures in a second place the temperature (T2) of the refrigerant in the direction of flow in front of the evaporator (10). A controlling variable is derived from this, which serves for adjustment of the expansion valve (5) in such a manner that there is a given superheating of the refrigerant overflowing into the compressor (1). It is envisaged that a further temperature sensor (21) is arranged in the refrigerant circuit. In this connection, two temperature sensors (20, 21) are to be situated in the wet steam region (X) in all operating states, so that a pressure drop takes place between them. The superheating of the refrigerant overflowing into the compressor (1) is determined from the temperatures (T1, T2, T3) determined with the temperature sensors, of which there are three in total. The controlling variable (4) is derived from this. <IMAGE>

Abstract: A method for determining the porosity of a subsurface geological formation traversed by a borehole is provided. The method generally comprises obtaining a means which relates ranges of apparent formation porosity (<pa) as determined by a neutron-neutron log, formation fluid salinities, formation total capture cross sections (E), formation matrix and fluid constituents, and true formation porosity (ϕ T ) according to a predetermined equation. The predetermined equation relates the apparent porosity to a function of a modified migration length which is obtained in a semi-empirical manner (i.e. physics modified by data). The modified migration length includes a slowing down length and a diffusion length, but causes at least the diffusion length to be a function of the slowing down length. The means which relates the apparent porosity to salinity, E, matrix and fluid constituents, and ϕ T  solves a forward problem. Thus, the inverse problem of determining true porosity may be solved by obtaining determinations of salinity, formation matrix and fluid constituents, E, and ϕa, and using the relating means to provide the true porosity. The provided method properly and separately accounts for the effects of capture cross section and salinity, and can be used to correct the apparent porosity determination of a neutron-neutron tool, regardless of the formation matrix or formation fluid constituents.

Abstract: The method described uses a pressure cooling apparatus for the guided cooling of shaped, heavy to light, hot continuous production material of steel and metal in pressurised water. In the method, use is made of one or more pressure chambers, the volume of which can be specified in accordance with production requirements. The volume is in each case delimited by two sharp-edged orifices or constrictions which form the latter. At least one cooling, one guiding and/or one condensation inlet for pressurised water is provided for each pressure chamber. The material to be cooled is subjected to a quantity of pressurised water which is necessary to remove heat from the production material, the pressurised water for cooling which flows into the pressure cooling apparatus - into the convection cooling part - being heated in the said part, together with the pressurised water for guiding, which flows in next to the cooling water, preferably to the boiling point. In the directly adjoining evaporation cooling part, the resulting hot water/steam mixture removes further heat from the production material by virtue of the required heat of evaporation from the hot water/steam mixture. The feed lines carrying pressurised water for cooling and condensation to the pressure cooling apparatus are dimensioned in such a way that the pressure losses in them are small, for which purpose flow-controllable valves with actuators are arranged in the feed lines concerned. <IMAGE>
