Abstract: A silicon-based sensor (10) includes a substrate (20), a sensor element (12), and a protective diaphragm (22a) mounting and covering the sensor element (12). The diaphragm (22a) is a silicon layer (22) which, in a preferred embodiment, includes an etch-stop dopant. The etch-stop layer (22) is sealed to the substrate (20) so that the layer (22) covers and mounts the sensor element (12) to the substrate (20). The sensor (10) is fabricated by forming a trough area (33) in a surface (32) of a silicon block (30) (e.g., a silicon chip or wafer), treating the trough area (33) with an etch-stop dopant (e.g., boron), depositing a sensor element (12) onto the doped trough area (33), sealing at least the periphery of the doped trough area (33) to a surface of a substrate (20) (e.g., glass) so as to encapsulate the sensor element (12), and then etching away undoped regions of the silicon block (30) so that the doped trough area (33) remains as a protective diaphragm (22a) sealed to the substrate (20) and covering the sensor element (12). It is also possible to form a bonding pad (16) on untreated (e.g., undoped) discontinuous regions (22c) of an otherwise etch-stop treated trough layer (34) so that when etched, the bonding pad (16) is exposed to permit interconnection with electronic circuitry, yet the etch-stop treated layer (22) remains so as to mount the bonding pad (16) to the substrate.

Abstract: A process for the preparation of a CFC-free foam from a thermoplastic, a nucleating agent and a blowing agent in an extruder is described, in which a second gaseous nucleating agent and a liquid blowing agent are sprayed into the plasticised plastic through spray orifices arranged downstream one behind the other. A gaseous nitrogen (N2) is sprayed in as a second nucleating agent in an amount of 0.1 to 0.5% by weight, and an alcohol of the group consisting of ethanol (C2H5OH), propan-2-ol (C3H7OH) and 2-methylpropan-2-ol (C4H9OH) or a mixture of these alcohols in liquid form is sprayed in as the blowing agent in an amount of 0.5 to 5% by weight, based on the weight of the plastic and of the first nucleating agent employed. A foam having a low density and a very uniform cell structure was obtained in a surprising and unexpected manner.

Abstract: An improved reclamation process for treating petroleum oil and water emulsions derived from producing or processing crude oil is disclosed. The process comprises heating the emulsion to a predetermined temperature at or above about 300 DEG  C. and pressurizing the emulsion to a predetermined pressure above the vapor pressure of water at the predetermined temperature. The emulsion is broken by containing the heated and pressurized fluid within a vessel at the predetermined temperature and pressure for a predetermined period of time to effectively separate the emulsion into substantially distinct first, second and third phases. The three phases are then separately withdrawn from the vessel, preferably without any appreciable reduction in temperature and pressure, and at least above a withdraw temperature of about 300 DEG  and above the vapor pressure of water at the withdraw temperature.
