Title: Method and apparatus for controlling coordinate displacements of a platform
Inventor: ENGELSE PETER D
IPC: G05B19/421
Filed: 1993-04-29
Abstract: The field of the invention is a combination of a microscope and an interactive image analysis system comprising a camera and a computer work station. The purpose of the invention is to facilitate the interactive control of coordinate displacements of the stage of the microscope. For each coordinate x and y an electromechanical control channel is established. At the input of the control channel two cascaded wheels in a coaxial arrangement and two angle encoders are used as a detached, independent tool which is not kinematically linked to the stage. In the middle of the control channel, the pulses of the angle encoders undergo a non-linear transformation. A processor performs a calculation which discriminates between slow displacements and fast displacements. At the end of the control channel, a flat, easily accessible platform of the microscope stage has two working areas, one for manual previewing and one for interactive scanning of a specimen.

IPC: B01D21/18
Filed: 1992-08-13
Abstract: A scum removal apparatus operable in association with a movable member operating within a sewage treatment pool is provided with a trough, a weir member and a transmission mechanism. The trough is fixed in position, and the transmission mechanism transmits a force from the movable member to the weir member to cause the latter to move up and down with respect to a fluid surface level. When the weir member is sunken, the scum is drawn into the trough, while when the weir member floats above the fluid surface level, the drawing of the scum into the trough is interrupted.  Support of the weir member is carried nut through a rotary shaft and the weir member is employed in the form of an elongated member having an elliptical cross-section so that the drawing of the scum can be carried out smoothly and stably with the transmission mechanism simplified in structure.      Sealing between the weir member and the trough is assuredly and simply achieved by a fixed-type sealing means on the side of the trough and end plates of the weir member.

IPC: C21D1/76
Filed: 1993-12-15
Abstract: An improved process for producing high-moisture containing nitrogen-based atmospheres suitable for oxide and decarburize annealing of carbon steels from non-cryogenically generated nitrogen is presented. These nitrogen-based atmospheres are produced by 1) mixing non-cryogenically generated nitrogen containing less than 5.0 vol.% residual oxygen with a specified amount of hydrogen, 2) humidifying the gaseous feed mixture, 3) feeding the gaseous mixture into the heating zone of a furnace through a diffuser, and 4) converting in-situ the residual oxygen present in it to moisture. According to the present invention, the total amount of hydrogen required for producing suitable atmospheres can be minimized by simultaneously humidifying the feed gas and controlling the residual oxygen level in it. The key features of the present invention include a) humidifying the feed gas prior to introducing it into the heating zone of a furnace operated above about 600°C, b) selecting the level of residual oxygen in the feed gas in such a way that it minimizes hydrogen consumption, and c) using enough amount of hydrogen to convert completely the residual oxygenpresent in the feed gas to moisture and to maintain pH2pH2O ratio in the heatingzone of the furnace below about 2 for oxide annealing and at least 2 for decarburize annealing carbon steels.

IPC: G01R31/316
Filed: 1994-03-21
Abstract: A device, such as an A/D converter for generating successive codes, each in accordance with the level of an input analog voltage, may be tested to determine if all codes have been generated by applying a voltage V, having an amplitude that varies between 0 and V volts. The variation in the voltage V, is such that when the device is operating properly, it will generate all of its codes during a predetermined interval. Each code generated by the device is compared by a comparator to the count of an.pi.-bit counter whose count is initialized at zero. Each time the count of the counter matches the code produced by the device, the counter is incremented. If the counter overflows (i.e., its count has exceeded 2.pi.-1) within a prescribed interval, then the device is said to be operating properly.
