Title: Machine tool for electrochemical machining by dimensions
Inventor: DRUZHKIN VLADIMIR I
IPC: B23H3/00
Filed: 1992-06-09
Granted: 1996-07-20
Abstract: FIELD: mechanical engineering. SUBSTANCE: invention relates to electrochemical machining of parts of mesh type with great number of holes. Machined part 1 is placed between curreent nonconductive stencils 2,3 anchored on cylindrical elements 5, 6 in which spaces inertia masses 7, 8 are positioned. Elements 5, 6 and stencils 7, 8 are joined into one unit and supported as cantilever on lid 9 of case-cylinder 10 installed on rod 14 of mechanism of reciprocating motion. Case-cylinder 10 is half-filled with electrolyte and half-filled with compressed air. It has source of electric energy and drive of reciprocating motion. Pressure of saturated vapour above electrolyte ensures its liquid state of matter with release of heat into working gap. Directed motion of inertia masses imparts circulation of electrolyte within machining zone removing released heat and products of machining. Intensity of hydrodynamic action of inertia masses on formed structure opf mesh is controlled by change of parameters of reciprocating motion. EFFECT: enhanced efficiency of electrochemical machining. 3 cl, 1 dwg

Title: Internal combustion engine exhaust gas pipeline
Inventor: SWARS HELMUT
IPC: F01N13/02
Filed: 1990-12-10
Granted: 1996-09-10
Abstract: FIELD: mechanical engineering; engines; exhaust systems. SUBSTANCE: catalyst heat carrier and/or diesel engine soot filter are arranged in second section of exhaust gas pipeline which adjoins first section at approximately right angle. Owing to special design of adapter body connecting both sections, exhaust gas moves along spiral line to provide inclined flowing around body. Thus load on body over cross section is levelled up and laminar flow in channels is delayed to enhance reaction with catalyst. Moreover, if necessary, sound isolation action can be provided owing to special structure of surfaces thanks to which service life of mufflers is increased and pressure losses in pipeline are reduced to minimum. EFFECT: enhanced operation of exhaust system.

Abstract: The invention relates to an electrostatic drive, in particular an electrostatic micro-drive, comprising a stationary component forming a stator, and a component forming an actuator movable in relation to the stator, one component thereof having at least two electrodes for producing an electrical driving field forming therebetween and the other having a material arranged in the electrical driving field and interacting electrostatically with the driving field. The drive also comprises a control circuit which varies the electrical field with respect to time such that the actuator is moved in a desired direction of movement. To improve the drive in such a manner that as large a torque as possible for a given electrical field intensity can be achieved, it is proposed that the material interacting electrostatically with the drive field comprises at least one substantially constant ferroelectric domain with one ferroelectric material substantially polarised in a constant manner in only one direction.

Title: Method of contact free longitudinal and transversal homogeneity examination of critical current density in strip supraconductors
Inventor: SCHILLER HEINZ-PETER
IPC: G01R33/12
Filed: 1997-04-24
Granted: 1998-04-23
Abstract: The method involves use of Hall probes (5,6) in a supraconductor (2) cooled to below a jump temperature (Tc). The supraconductor (2) is drawn through an external locally defined magnetic field with a constant gradient. The magnetic field axis (8) is not varied during the measurement. The magnetic field originates from the screen currents induced by the region of the conductor (2) through which the external magnetic field passes. The resulting magnetic field is scanned with a first Hall probe (5). A similar Hall probe (6) used as a compensation Hall probe measures the external magnetic field outside the field region of the induced currents. Next in an empty measurement without test piece, the external magnetic field alone is measured by both Hall probes and the difference between the Hall probe signals is equalised to zero. The difference between the Hall probe signals is used as a qualitative measurement for the locally varying critical current density and its longitudinal homogeneity. A linear Hall probe array (5) is arranged perpendicular to the longitudinal axis of the supraconductor (2) and extends over the wide side of the conductor. The array (5) measures the transverse homogeneity. Next, for all Hall probes of the array (5) is carried out with the signal of the compensation probe (6). The local critical current density is quantitatively output from the Hall probe signals via a resistive calibration or current and voltage measurement.
