摘要： According to an illustrative embodiment of the invention, a technique is described for producing signals varying as a function of the distance of a surface relative to a reference face, comprising transmitting a beam of coherent light to an admitting end of a fiber optic bundle to transmit light to a reflecting surface opposite an emitting end of the bundle. A fiber optic receiver bundle having at least one receiving end for picking up light reflected by the surface is provided for transmitting a flux of reflected light to produce a signal related to this relative distance by a linear relationship over a certain range of variation of such distance. Such range may be varied by varying the angle of incidence of the coherent light beam on the admitting end. The receiving end may be transversely separated from the emitting end by an amount selected in accordance with a desired angle of incidence and a predetermined range. For the purpose of measuring the thickness of transparent bodies as measured by the distance between an outer and an inner face thereof opposite the emitting end, first and second respective receiving ends are provided such that light reflected by the inner face cannot be picked up by the first receiving end and vice-versa. A simple technique for determining the effects of variations of reflectivity of a light reflecting surface is also disclosed.

摘要： There is disclosed a dual beam gas analyzer and the mode of operation thereof for measuring small concentrations of a gas of interest in the presence of another gas having absorption bands overlapping those of the gas of interest. This is encountered in the determination of the concentration of CO2, CO, CH4, C2H2, NH3 or SO2 in the presence of CH4, CO2, CO2, CO2 or CH4 respectively. The dual beam gas analyzer comprises a source of infrared rays providing an infrared beam which is directed into one end of an analysis chamber through an optical commutator. The optical commutator directs alternately and periodically the infrared beam to a comparison filter transparent to the infrared beam and to a gaseous filter absorbing completely the energies of the absorption bands of the gas to be measured. The output signals of a non-selective radiation detector disposed at the other end of the analysis chamber are applied to electronic circuits which provide a signal representative of the difference between the energies of the two successive beams passing through the analysis chamber. A movable shutter permits one to modify the energy of the beam corresponding to the comparison filter and is adjusted to eliminate the influence of the other gas on the determination of the concentration of the gas of interest. According to one embodiment an auxiliary tube is placed along the path of the beam passing through the gaseous filter to increase the precision of the gas analyzer in cases where the concentrations to be measured are in the range of a few tens ppm.

摘要： A gate for closing a corridor is provided, the gate having driving means and means to terminate its motion if an opposing force is applied while the gate is being closed. The gate is mounted on a fixed axis and the apparatus rotates about a fixed hub. The driving force to close the gate is applied to a rotatable member which rotates about the axis of the hub and which is coupled to a second rotating member through a lost motion coupling and a spring, which spring transmits the driving force. The second rotating member carries and rotates the gate. If a force is applied to the gate in a direction which would oppose the closing motion, and which is of sufficient magnitude, the spring extends and the lost motion coupling permits relative movement between the first and second members. A plurality of fingers carried by the first member are then moved an amount sufficient to permit a locking apparatus to engage the hub and the second member, preventing further rotary motion between these members until the force is removed and the spring recovers the motion in the lost motion coupling. The locking device disclosed includes a plurality of surfaces formed on the second member, which surfaces slope toward the hub and form, with corresponding surface portions on the hub, converging channels. A plurality of rollers are disposed in the large ends of these channels, the rollers being urged toward the small ends of the converging channels by springs. During normal rotation, a plurality of fingers carried by the first member keep the rollers out of contact with the hub, but when the spring in the lost motion coupling is extended and the first member moves relative to the second, the fingers move away from the rollers, allowing their respective springs to urge them into contact with the walls of the converging channls, thereby locking the hub and second member together.

摘要： A temperature correction device for a volume gas meter comprises a first shaft which rotates at a first speed proportional to the volume flow rate of gas. A magnetic slip clutch couples the first shaft to a second shaft and a magnetic brake develops a torque on the second shaft. The magnetic slip clutch and the magnetic brake each comprise a non-ferromagnetic metal disk and at least one permanent magnet with thermomagnetic shunts. The resistivities of the disks and the thermomagnetic shunts are chosen such that the ratio of the second speed to the first speed varies as a function of the temperature according to a law which is reverse of that of the variation of the volume of the gas. A totalizer is coupled to the second shaft and gives an indication of the volume which is independent of the temperature. The temperature correction device is enclosed in an envelope which communicates with the gas to be measured. In a second embodiment, the two non-ferromagnetic metal disks are combined to constitute a single disk made of two different materials or of the same material.

摘要： According to an illustrative embodiment, a mechanism is provided for throttling a fluid flowing through an opening in a body between two regions at different pressures. A first and a second throttling flow paths are provided through said opening by means of a valve member movable between a first and a second position. First seal means are provided around this opening for sealingly engaging such valve member in the first position thereof to close the first flow path. This first flow path is opened by movement of the valve member toward its second position for throttling a first flow of fluid. Means movable with the valve member between the first and second positions thereof are also provided for controlling the displacement of the valve member, the pressure difference between the two regions acting to urge the valve member into sealing engagement with second seat means carried by the movable controlling means, between the first and up to the second position of the valve member. A tubular extension surrounding the opening has lateral throttling apertures formed therein the lateral wall of the valve member is arranged to progressively uncover larger portions of the apertures when moving from first to second position, thus varying the section of the first flow path in a non-linear manner with the displacement of the valve member. Abutment means are provided to maintain the valve member in its second position whereby the second flow path opens upon movement of the controlling means with respect to the valve member in the section position, the flow throttling section of such second flow path varying linearly with the latter movement.

摘要： Two polarized light beams from the same source are rotated by passage through Faraday rods having windings supplied by a current to be measured. The beams are then counterrotated by passage through second Faraday rods having windings supplied by a compensating current. Each beam is then applied to a beam splitting semi-reflective mirror which displaces it into distinguishable components. Optical analyzers then attenuate each beam in accordance with a function of the angular displacement from reference or preferential polarization planes. Pairs of photoresponsive detectors transduce the resulting beams into pairs of electrical signals, each pair having a signal of different sign or sense. Signals of like sign are then combined and the two resulting signals are applied to the two inputs of a differential amplifier. The amplifier output is used to develop a proportional compensation signal for the second Faraday rods and can be displayed as a measure of input current.
