IPC: H03F1/30

Abstract: A variable input voltage is periodically introduced in first time periods to an amplifier such as a differential amplifier to obtain an output from the amplifier. The amplifier may receive a reference voltage at one input terminal and the input voltage at a second input terminal in the first time periods. The input to the amplifier is periodically shorted in second time periods alternating with the first time periods so that the reference voltage is applied to both input terminals. Any offset voltage from the amplifier in the second time period may be converted to a binary signal to indicate the polarity of the offset voltage. The binary signal may be introduced to a storage member such as a capacitance. The capacitance accumulates energy in accordance with the characteristics of the binary signal in successive ones of the second time periods. The energy in the capacitance is introduced to the output terminals of the amplifier in a direction to compensate for the offset voltage in the amplifier. First switches may prevent the energy in the capacitance from being introduced to the output terminals of the amplifier during the second time periods. Second switches may prevent the capacitance from being charged by the output from the amplifier during the first time periods.

Abstract: The base current regulation according to the invention is particularly used for freely adjusting the desired saturation level of a power transistor (T1) in the switched-on state. For this purpose, a saturation-level regulation (SBR) operating in parallel provides, by evaluating the voltage (UCET1) at the output of the power transistor, picked up by means of a coupling diode (D2), an auxiliary correcting variable ( DELTA iBT1) in the small-single range. This is preferably supplied to the input of a power controller (LSG) in a controlled driver stage (STS) which provides the actual driving energy (SE) for the base current (IBT1) of the power transistor (T1). …<IMAGE>…

Abstract: A three-dimensional shape measurement apparatus uses a laser beam(2) to illuminate an object(14). The light reflected from the object is processed to obtain information about the shape of the object in three dimensions. As the beam moves over contour features of the object, there is a corresponding displacement of the focal point of the light reflected back from the object which is calculated to convert it to depth-wise shape information. The apparatus includes a laser light source(1); deflectors(6,17) for scanning the laser beam at a set frequency; an optical system (19) for projecting the laser beam scanned by the optical deflectors at the object; detection slits(22,27) arranged parallel to the direction in which the reflected light is scanned on an optical axis that is perpendicular to the direction of the scanning by the optical deflectors, the slits being placed a certain distance from a point that is optically conjugate with the object; photosensors(24,30) for detecting light passing through the detection slits; and a signal processor (39) to eliminate the effect of the reflection characteristics of the object.

Abstract: In a scrub-clearing tool, of the type comprising a tube (2), a blade (3) supported for rotation at one end of the tube, a motor (3a) for driving the blade (3) and a transmission shaft for connecting the drive motor (3a) to the blade (3), a disc (6) is provided for protecting the blade and is mounted for rotation on the shaft of the blade (3) with the interposition of a bearing (16). The protective disc (6) has a diameter larger than the outer diameter of the blade (3) and has a plurality of recesses (7) around its periphery, the inner edges whereof are spaced from the centre of the disc by a distance less than the radius of the outer circumference of the blade (3). The protective disc (6) is normally rotated together with the blade (3). It stops when it comes into contact with the ground or with some obstacle, whilst the blade (3) can continue to rotate by virtue of the presence of the bearing (16). The disc (6) therefore protects the blade (3) from impacts with obstacles, protects the operator from accidental direct contact with the blade (3), and finally prevents the cutting of woody stems of a diameter greater than the width of the recesses. In fact, larger stems cannot penetrate these recesses (17) and hence are not cut by the blade.

Inventor: MALDAGUE PIERRE
IPC: B01D45/16
Filed: 1988-05-09
Abstract: This disclosure includes a process and apparatus for subsonic aerodynamic separation of components existing in condensed and/or condensable form in a gaseous stream, in which the gaseous stream undergoes successively an expansion up to high subsonic velocities and a recompression by deceleration, with inertial separation of the pre-existing particles as well as of the particles formed and/or enlarged by condensation. Within the flowing gaseous stream, a gradient of concentration of the particles is created, in the same direction as the pressure gradient within the stream. Separation of the particles occurs in an axisymmetric chamber bounded by an outer wall and an inner core and including a fixed array of deflecting blades for transforming the essentially axial motion of the stream entering the chamber into an helico-spiral motion, and a fixed array of straightening blades for transforming the helico-spiral motion of the stream before its exits from the chamber into an essentially axial motion. The inlet and outlet cross-­sections of each array are cylindrical surfaces coaxial with the outer wall and the inner core. Condensation occurs by expansion of the gaseous stream particularly in an inner zone between the arrays at high subsonic velocity. Expansion is identical along all streamlines within the gaseous stream and the particles separating from each streamline of the gaseous stream are subject to identical centrifugal forces driving them towards the outer layer of the gaseous stream.

Abstract: Procédé de décarburisation rapide de fonte brute à haute teneur en Cr à la pression atmosphérique, réduisant les pertes de Cr dues à l'oxydation. Une caractéristique principale de ce procédé consiste en ce que l'on insuffle depuis le haut, par l'intermédiaire d'une tuyère supérieure, du O2 décarburisant dilué avec un gaz inerte contre la fonte brute à haute teneur en Cr en fusion dans un récipient, et que l'on insuffle simultanément un gaz inerte par l'intermédiaire d'une tuyère inférieure, afin d'agiter fortement la fonte brute en fusion. Une autre caractéristique du procédé consiste en ce que l'on fait varier la quantité de laitier pendant que l'on insuffle le gaz décarburisant, afin de limiter les pertes de Cr dues à l'oxydation. Encore une autre caractéristique consiste en ce que l'on effectue une dénitruration déterminée après avoir insufflé ledit gaz, de manière à produire du fer en fusion à basse teneur en azote, présentant de faibles pertes de Cr dues à l'oxydation.

Abstract: In a process for the preparation of 5-bromo-5-nitro-1,3-dioxane from 2-nitro-1,3-propanediol, it is desired to use non-prepurified 2-bromo-2-nitro-1,3-propanediol as the starting material on an industrial scale without using organic solvents. This was achieved by pumping in a first step a mixture of bromine and aqueous hydrogen bromide solution via a heat exchanger in a cycle and metering in the aqueous solution of an alkali metal salt or alkaline earth metal salt of 2-nitro-1,3-propanediol upstream from the heat exchanger at such a rate with cooling that the maximum reaction temperature does not exceed 30 DEG C and then adding, in a second reaction step, paraformaldehyde and sulphuric acid, allowing the reaction to go to completion above room temperature and separating off the organic phase.
