Patent DE-19942138-A1 (DE)
Title: Time-difference method of measuring fluid flow rate; involves using ultrasound to calculate through flow of fluid in large river or open channel or of gas in large pipe
Inventor: CHANG HAK SOO
IPC: G01P5/24
Filed: 1999-09-03
Abstract: The method involves amplitude modulating an ultrasound carrier signal with a central frequency, which is less than that of the carrier over a given period. The amplitude modulated signal is transmitted in the same and the opposite direction as the flow. The time between when the carrier is amplitude modulated and when the amplitude modulated received signal is detected and demodulated is used to calculate the speed of flow.  The method involves amplitude modulating an ultrasound carrier signal with a central frequency to an amplitude modulated frequency which is less than the frequency, fc, of the carrier over a given period whenever the ultrasound propagation time is to be measured. The amplitude modulated signal is transmitted in the same and the opposite direction as the flow. The received signal is then demodulated. The time between when the carrier is amplitude modulated and when the amplitude modulated received signal is detected is then measured and used to calculate the speed of flow, according to the equation: fp  <=  <=  10(Cmax + Vmax cos  alpha )/L <=  f  <=  0.05fc, where fp is a maximum frequency, by which the damping factor for the transmission time of the ultrasound in the fluid fluctuates, Cmax is a maximum speed of sound in the fluid, L is the length of the path by which ultrasound is transmitted, and  alpha is the angle between the ultrasound transmission path and the direction of fluid flow. An Independent claim is included for a phase-difference method for measuring fluid flow rate, which involves transmitting an ultrasound wave at a constant angle relative to the flow.

Abstract: A toothed selector clutch is provided to operate in a hydrostatic/mechanical, split-torque power-shift transmission comprising a four-shaft epicyclic-gearwheel transmission and an infinitely variable hydrostatic transmission arranged in parallel. The selector clutch is associated with a particular gearwheel stage and is operated to select a particular gear. Gear changes take place at synchronous speeds without loading the engaging gear during the change and without interruption of the transmission of torque from the rotating shaft to the gear being disengaged. The toothed selector clutch is a coaxial double differential clutch with a clutch carrier that is arranged in a rotationally and axially fixed manner on a clutch shaft. A double piston, which can be subjected to a pressure medium on both sides, is provided as a shift bridge and is operatively connected to the clutch carrier by toothing thereby permitting torque transmission and axial displacement. The shift bridge carries shift toothing on each of its axially opposite ends and is acted upon from two separately controllable pressure spaces. When the shift bridge is subjected to pressure from both ends simultaneously, it remains or moves into its neutral, central position. Engagement of one of the two gears associated with the clutch may be accomplished depressurizing the pressure space assigned to the other gear causing the shift bridge to move axially and engage the intended gear.

Abstract: Ein Laserkopf wird annähernd zentrisch und rotierbar in einen Hohlzylinder eingebracht. Die zugehörige Rotationsbewegung des Laserkopfes erfolgt im wesentlichen um die Längsachse des Hohlzylinders, während die Ausrichtung des Laserstrahls nur angenähert mit der Längsachse des Hohlzylinders übereinstimmt. Bei Drehung des Laserkopfes wird eine hyperboloidförmige Lichtstrahlen-Schar generiert. Diese Lichtstrahlen erzeugen auf einem ausserhalb des Hohlzylinders angebrachten Target ein praktisch kreisförmiges Projektionsmuster. Das Projektionsmuster definiert mit seinem Zentrum einen Punkt auf einer dem Hohlzylinder zugeordneten ideellen Achse (Seele). Die Erfindung eignet sich insbesondere zur Vermessung von Wellentunneln von Schiffen, aber auch zur Verlegung von grossdimensionierten Rohrsystemen wie Pipelines. <IMAGE>

Abstract: The sterilization method disclosed includes the steps of providing a sterilization chamber; placing the article into the sterilization chamber; sealing the sterilization chamber; applying a vacuum of a preselected vacuum pressure to the sterilization chamber; supplying water vapour to the sterilization chamber under vacuum; supplying ozone-containing gas to the sterilization chamber; maintaining the sterilization chamber sealed for a preselected treatment period; and releasing the vacuum in the sterilization chamber, whereby a vacuum pressure is used which lowers the boiling temperature of water in the sterilization chamber below the temperature in the sterilization chamber. One or more ventilating cycles can be added to the preferred method for removing the remaining ozone and humidity from the sterilization chamber. Single cycle sterilization with ozone is more efficient and provides for a shorter sterilization cycle than with ETO and requires few changes in user habits. Moreover, the ozone-based process in accordance with the invention is compatible for use with current packaging, such as sterile pouches and rigid containers. The sterilization process is simple and substantially avoids human errors caused by false interpretation and handling. The ozone sterilization method of the invention requires substantially no aeration or cooling down of sterilized instruments so that they can be used immediately following the sterilization cycle. This allows hospitals to reduce the cost of maintaining expensive medical device inventories.
