Title: Probe-type hydrogen concentration sensor for f-p interferometers based on hollow-core fibers
Inventor: JIANQING LI
IPC: G01N21/45
Filed: 2022-07-07
Abstract: A probe—type hydrogen concentration sensor for Fabry—Perot (F—P) interferometers based on hollow—core fibers is disclosed. The sensor‘ is composed, of a tunable lasery a circulatory a sensing head, a hydrogen generator, a photoelectric detector, and an 5 oscilloscope. An F—P interferometer is formed, in a hollow—core fiber by end faces of a single—mode fiber and a tapered single— mode fiber. A taper waist portion of the tapered single—mode fiber is coated with a palladium—silver alloy film. The volume of the palladium—silver alloy film is expanded in the presence of 10 hydrogen, whereby the eigenfreguency of a fiber taper forming a cantilever beam structure is changed. During application, a hydrogen concentration change may be demodulated by monitoring a variation of the eigenfreguency of the sensor. A response speed of the sensor in the present invention is higher than that of a WOy- 15 based hydrogen concentration sensor. (+ Fig. l)
Patent NL-6501633-A (NL)
IPC: B01J19/00
Filed: 1965-02-10
Abstract: Melamine is separated from a gaseous mixture containing melamine, ammonia and carbon dioxide by diverting and accelerating the gaseous mixture into a downwardly restricted flow path by means of a gas baffle which is at a temperature above 610 DEG  F, and projecting an aqueous liquor transversely into the gaseous mixture below the downwardly restricted flow path, to form a slurry of solid melamine in the aqueous liquor.  The gaseous mixture is usually at 650-800 DEG F. and is that obtained in the catalytic conversion of urea to melamine.  It is preferred to use an aqueous liquor containing 1-10% by wt. solid melamine which has been used in a previous cooling cycle and which is at 150-170 DEG  F.  The rapid quenching gives a solid product which is free from the usual melamine contaminants.  The process is illustrated by reference to drawings (not shown) of a suitable apparatus.ALSO:An apparatus, which may be used for condensing melamine from a gaseous mixture, comprises a vertical vessel provided with a gas baffle extending across the vessel and having a central aperture, a vertical passage extending downwards from said aperture to define a gas flow path and a projector positioned below said vertical passage to project aqueous liquor transverse to the gas flow path.  In a preferred embodiment the vertical vessel is cylindrical, the gas baffle is horizontal and forms a disc with a round aperture, the vertical gas passage is cylindrical and the projector comprises a downwardly converging side wall terminating at a lower outlet disposed below the vertical gas passage, the lower outlet of said wall being defined by a horizontal projection lip.  For use in the separation of melamine, the gas baffle is insulated and/or provided with heaters, e.g. electric resistor elements, to maintain the upper surface of the baffle at a temperature above 610 DEG F.  The apparatus is described with reference to drawings (not shown).

Title: Shut=down circuit for computer-operated process - compares generated pulse with that processed by computer to ensure correct operation
IPC: G06F11/00
Filed: 1981-12-04
Abstract: This shut-down circuit stops an automatic processing system (3) if the computer (1) which controls the process is faulty. A generator (4) delivers a pulsed reference signal to the computer (1) and one input of the signal comparator (5). If the computer is working correctly, it treats the pulse as an interrupt and produces an identical signal which is fed to the other input of the comparator, via a low pass filter (7) which removes any undesired h.f. components. If the comparator detects problems with the computer, it delivers a signal to the process cut-out circuit (6), and shuts down the process. A feedback link (8) from the cut-out circuit to the computer forces the computer to yield control if the cut-out does not work. A process monitoring signal (9) to the computer may be used to provide extra protection.
