    摘要： A flow regulator has a pair of side walls extending generally parallel to one another, a bottom wall connecting the side walls to one another and defining an elongate channel for receiving a compressible tube, a roller rotatably and shiftably mounted to the side walls for rolling along the tube in the channel and compressing the tube against the bottom wall. The bottom wall is provided with a formation which varies from a first end of the channel towards an opposite, second end thereof, whereby compressive force applied to the tube via the roller is different at different longitudinal positions of the roller along the channel. A bracket or bow-shaped bridge is disposed about or between the side walls at one end of the channel. The bracket is in contact with outer surfaces of the side walls only in regions of the side walls spaced from the bottom wall. The bracket or bridge is advantageously made with less inherent stiffness than the assembly defining the elongate channel. In an alternative embodiment, the side walls are thicker at discrete positions along the side walls to eliminate the need for a bracket or bridge. In another alternative embodiment, the side walls extend from the bottom wall at less than ninety degree angles such that the distance between the free ends of the side walls are smaller than the distance between the side walls at the bottom wall.

    摘要： A process for the dynamic manufacture and packaging of gas mixtures containing a first component and a second component in predefined proportions, the first and second components being chosen from the group formed by O2, N2, He and N2O, in which predetermined proportions of the first and second components are dynamically mixed in order to obtain a gas mixture of the desired composition and the temperature of the mixture is adjusted in order to keep it above the demixing threshold temperature of the mixture. This process is particularly suitable for the production of analgesic gas mixtures that can be used in the medical field, particularly a mixture formed from 50% oxygen and 50% nitrous oxide.

    摘要： The ratio of fuel to oxidant in a gas mixture to main burners in a furnace, wherein the fuel is of variable composition, is controlled to a predetermined level by burning a portion of the fuel in a control burner, adjusting the oxidant to obtain a ratio of fuel to oxidant near the stoichiometric ratio in the control burner and supplying the main burners with independent preset multiples of the fuel and oxidant flow in the control burner such that the predetermined ratio of fuel to oxidant is achieved.The stoichiometric ratio is determined by automatic searching for the peak value of a burning or burned fuel property which has a maximum value as a function of the fuel/oxidant ratio at or near the stoichiometric ratio. For example, the temperature of the burned fuel is a property which may be used to find the stoichiometric ratio.The method and apparatus for controlling burner stoichiometry may be used for improving burner efficiency and reducing pollution or it may be used to control the atmosphere of a furnace anywhere between oxidizing and reducing conditions.

    摘要： An improved apparatus for monitoring and controlling the composition of a flammable gas mixture to prevent accumulation of explosive gas mixtures in a substantially closed container. The apparatus includes a combustion chamber through which a sample stream of gas mixture is propelled. In operating the apparatus, the mixture within the combustion chamber is subjected to a series of high voltage ignition charges by means of an automotive spark plug which receives ignition charges from a conventional automotive capacitor discharge ignition system power unit and automotive ignition coil with the ignition charges being triggered by an electrically powered oscillator at a frequency preferably between 10 and 20 Hz. The electrical components and combustion chamber are housed within an explosion proof housing. A temperature responsive switch within the combustion chamber causes the actuation of solenoid operated pneumatic valves to provide continuing visual indication of the status of the system and provide injection of non-combustion-supporting gas into the closed container to prevent accumulation of explosive mixtures therein.
