Abstract: A three-dimensional optical scanning vision system capable of producing high-resolution images in real-time includes an optical source (100) for producing a source light beam. The source light beam is directed to a beam splitter (104) which splits it into a local oscillator beam and a signal beam. The local oscillator beam is directed toward a photodetector (106), while the signal light beam is directed toward a target (112). Light reflected from the target (112) is received by the beam splitter (104) and directed toward a retroreflector (118) which returns the beam to the beam splitter (104) interface. Quarter wave plates (110,116) and the retroreflector (118) insure that the return light beam and the local oscillator beam are collimated and have the same polarization state. Mixing the local oscillator beam and the return light beam occurs at the beam splitter (104) interface, thus providing coherent optical detection by the photodetector (106). The photodetector thus provides an output signal providing a high degree of information about the target. The system also includes scanner optics (2) to scan the signal light beam across the target. A processor (20) is also included for outputting a three-dimensional image of the target, and for controlling the scanner optics (2).

Title: Method and apparatus for conducting chemical reactions at supercritical conditions
IPC: B01J3/00
Filed: 1988-03-31
Granted: 1992-06-03
Abstract: A continuously flowing fluid is processed by being fed to the top of a hydraulic downdraft column (17) which is of a height such that the pressure at the bottom thereof will approximately be at the pressure necessary to create supercritical water conditions. The fluid is conducted to the bottom of the column (17) and received in a reaction chamber (21) in which the majority of the fluid is recirculated around an annular baffle plate (24). The material in the reaction chamber (21) is heated to a temperature above that necessary to create supercritical water conditions by an independent reaction taking place in a heating chamber (32). The result is that the fluid will undergo chemical reactions at the supercritical temperature and pressure range and will be of a lower specific gravity than the unprocessed fluid. The material not being recirculated in the chamber (21) is fed to one of two updraft columns (30, 31), a start-up column (30) used to preheat the material in the downdraft column (17) during initiation of the process, and a second column ( 31) isolated from the downdraft column (17) so as not to transmit any heat thereto during normal operation of the process. The temperature of the fluid in the downdraft column (17) is thereby controlled to prevent decomposition of the material until the fluid enters the reaction chamber (21) at which time it is abruptly brought up to the supercritical water temperature.

Abstract: La présente invention se rapporte à un dispositif d'alimentation en fil pour une machine à fil de coupe par électroérosion qui est capable d'effectuer, lors d'une opération d'usinage par décharges électriques, le retrait d'une courroie de transfert de fil à partir d'une position dans laquelle les fils sont connectés automatiquement, empêchant ainsi l'usure de la courroie et les fluctuations de la vitesse d'avance des fils. Afin d'effectuer une opération de connexion automatique des fils, on active un vérin automatique (27) pour un mécanisme d'alimentation en fil (16). Ainsi, une seconde courroie de transfert (15') se déplace d'une position de retrait vers une position de connexion automatique via un mécanisme de liaison parallèle (23, 25, 25', 25''), position dans laquelle la seconde courroie de transfert (15') vient se plaquer contre une première courroie de transfert (15). Lorsqu'on actionne un moteur (M2) pour faire tourner les deux courroies, un fil-électrode (5) tenu entre les deux courroies se déplace du côté amont d'un trajet du transfert du fil vers un côté aval de ce trajet pour compléter l'opération de connexion automatique. Lorsque le vérin pneumatique est ensuite désactivé, la seconde courroie de transfert retourne à la position de retrait grâce à l'action élastique d'un ressort (26), se séparant ainsi de la première courroie de transfert. En conséquence, le fil électrode et les deux courroies sont placés hors contact, empêchant ainsi l'usure du fil et les fluctuations de la vitesse d'alimentation du fil.

Granted: 1992-07-08
Abstract: The ski boot comprises a lower shell (1) with which a rear portion (2) of the shaft and a front portion (3) of the shaft are connected so as to be articulated. The lower shell (1) comprises a cut out portion (7) in the rear in the area which is provided for enclosing the lower leg, an insert piece (8) which is arranged at the rear portion (2) of the shaft being insertable in the cut out portion (7). The inclination position of the rear portion (2) of the shaft, and accordingly the inclination position of the entire shaft, can be determined by means of the cooperation of the flanks (7a, 8a) of the cut out portion (7) and the insert piece (8) which extend in the longitudinal direction of the shaft, which inclination position can be varied by means of insert pieces (8) having different radian measures. A clamping device (10, 11) which, in addition to a heel pull (17, 18), is supported at the lower shell (1) serves to fix this inclination position. The ski boot has a great degree of comfort due to the shaft portion (2), which can be swiveled back, and has athletic characteristics due to the shaft which is adjustable with respect to the inclination position and encloses the lower leg of the wearer.

Abstract: The present invention relates to a time display device comprising a digital display unit (50) for displaying the passage of time set in an electric appliance whose operating time, for instance, can be preset. The time display device is arranged according to the present invention so that a display control switches the display operation performed by the digital display unit (50) to a flickering operation when temperature sensors installed in the electric appliance are turned on, whereby the user is informed of the temperature of the electric appliance exceeding a predetermined value. Instead of the provision of an alarm of this sort such as an alarm buzzer or lamp as in the case of prior art, the provision of such a time display device permits of dispensing with a particular alarm device, so that an increase in the number of parts and therefore an increase in production cost can be prevented.

Abstract: A directional drilling apparatus and method in which the drill bit is coupled to the lower end of a drill string through a universal joint (20, 40) which allows the bit to pivot relative to the string axis. The bit is contra-nutated in an orbit of fixed radius and at a rate equal to string rotation but in the opposite direction. This speed-controlled and phase-controlled bit nutation keeps the bit heading off-axis in a fixed direction. The invention enables directional drilling while the drill string rotates normally.

Abstract: Current pulses are conducted through an inductance by means of a switching transistor. The switching transistor is controlled by means of an amplifier and pulse shaper circuit in such a manner that a constant average direct current flows in a closed loop comprising said inductance and a recovery diode, resulting in a regulated, constant output voltage across two Zener diodes. This allows a particularly effective operation with relatively low power losses in said switching transistor as compared to the utility current at the output terminals, and the circuit operates reliably in a wide range of operating voltages.
