Inventor: WIDENER STANLEY KEVIN
IPC: F02C7/057
Filed: 1991-11-05
Abstract: A method of diffusing airflow includes diffusing first and second airflow portions at first and second diffusion rates, respectively, which are unequal for improving pressure recovery. An exemplary diffuser (56) for practicing the invention includes first and second channels separated by a splitter (84) for separately diffusing first (50A) and second (50B) airflow portions, respectively. The first and second channels have first and second area ratios, respectively, which are unequal for obtaining increased pressure recovery. In the preferred embodiment, the first and second area ratios are preselected for obtaining substantially symmetrical airflow streamlines over a leading edge of the splitter.

Abstract: The invention relates to a procedure for manufacturing an impregnated cathode for an electron tube and to the impregnated cathode obtained therewith. The method involves mixing (b) a powder (Y) containing the emissive element (generally aluminates of barium and calcium) with the powder (W) of at least one refractory element (generally tungsten, possibly mixed with a platinum ore metal). This is followed by pressing (c) the mixture to form a pellet (1) which is then sintered (d) at a high temperature (about 2000 DEG C) in a hydrogen atmosphere. In the prior art, a powder of at least one refractory metal was pressed and sintered, and then impregnated, machined, cleaned, etc. The method of the invention thus enables many stages in the manufacture of an impregnated cathode to be omitted in comparison with the prior art. <IMAGE>

IPC: A61F2/02

Abstract: High-strength, high-modulus, polymeric implants are produced from highly oriented monofilaments and/or films by solvent welding technique. This avoids loss of orientation, as well as thermal and oxidative degradation, which is the common case with the state of art techniques, namely melt extrusion, injection molding and heat compression molding. The invention leads to uniform bonding of the separate structural units (monofilaments or films) into compound-filament or compound-laminate which protects the implant against delamination. Monofilaments of films are swollen at the surface with a suitable solvent which does not destroy the orientation in the core. A bundle, resp. a sandwich of the swollen monofilaments or films is pulled through an orifice generating compressive stresses between the filaments, resp. films. Solvent removal from the swollen compressed interfaces leads to a homogenous welding of the monofilaments or films.

Abstract: An accelerometer (10) with improved drop resistance for regulating automotive safety air-bag systems and the like. The device comprises a member (16) of silicon semiconducting material having a central seismic mass (26) mounted on a surrounding support (30) by intervening beams (32) , a pair of beams extending from each of four sides of the mass to the support and the mass being otherwise free of connection to the support to permit movement of the mass along an axis perpendicular to the plane of the support in highly sensitive response to acceleration forces along that axis. Each beam extends from a location near an end of one side of the mass so that the two beams extending from each side of the mass are widely spaced relative to each other to oppose rotational or twisting movement of the mass in response to off-axis acceleration forces to prevent damage to the beams during dropping of the accelerometer to the extent possible consistent with providing the desired sensitivity of response. Piezoresistive sensors are accommodated in selected beams to sense strain during movement of the mass to provide an output signal corresponding to acceleration force along the device axis. Stops limit movement of the mass along that axis to further avoid damage to the beams.
