Title: Process for the further processing of  hydrogen sulphide-containing gases
Inventor: WERNER ERIK S E
IPC: C01B17/04
Filed: 1979-04-19
Granted: 1982-09-21
Abstract: ABSTRACT OF THE DISCLOSURE         A process for treating H2S-containing gases which have also a relatively high CO2 content, wherein sulphur-containing compounds of said gases are converted to elemental sulphur in a Calus plant.  The process is applied to gases having a calculated H2S/CO2 ratio of less than 1.  In a first absorption zone sulphur-containing compounds (H2S, COS, CS2) and CO2 are absorbed in a liquid under non-selective absorption conditions, and after regen-eration of said absorption liquid, partly fed to a Claus plant and partly to a catalytic reduction zone.  The off-gas of the Claus plant is also introduced in said reduction zone wherein any sulphur compounds other than H2S are converted into H2S in the presence of H2and/or CO.  The gas mixture leaving the reduction zone is treated for H2S removal in a second absorption zone with the same liquid as applied in said first zone under conditions which are selective in respect of co-absorption of CO2.  The H2S containing absorption liquid  of said second zone is regenerated in a regeneration zone common to the first and second absorption zone, whereby the cal-culated H2S/CO2 ratio of the feed to the Claus plant is improved.

Patent CA-1121780-A (CA)
Title: Optical fiber breaker and method, and combination  breaker and optical connector
Inventor: DOTY JOHN S
IPC: G02B6/245
Filed: 1979-05-11
Granted: 1982-04-13
Abstract: Abstract The present apparatus and method make it extremely easy for a worker, even when located in a manhole or on a telephone pole, to rapidly achieve a perfect break in an optical fiber and at a precisely predetermined position relative to a connector means.  The breaking is the same, regardless of the upright, in-verted or inclined position of the tool.  Only a single motion of the blade is required at any desired speed, and there is no neces-sity for the blade to contact the fiber at a pressure within certain limits.  These and other major results are obtained by clamping an optical connector element to the optical fiber before breaking is effected, and then removably securing the connector element to the breaker at a precisely known position which is correlated to the location of the scoring blade and to the charac-teristics of the connector.  The fiber is then clamped, bent, tensioned and scored in response to a single squeezing and releas-ing motion by one hand of the operator-- these actions being sub-stantially entirely unaffected by excessively hard squeezing forces.          The scoring is effected by a hard-mounted tungsten carbide blade which moves, in an arcuate path, toward and across the tensioned fiber.  The blade is of a certain type which-- when thus moved--causes scoring to occur so instantaneously that, despite the indicated hard mounting, there is almost no danger that the fiber end will be crushed or otherwise damaged.  In a second embodiment, means are provided to heat the fiber for rapid burning of the syn-thetic  resin coating therefrom.  The invention includes not only the breaker and method per se, but also the apparatus and method whereby the breaker is combined with an optical connector to create a combination breaker and connector.

Abstract: ABSTRACT OF THE DISCLOSURE     An arrangement for regulating the flow of a gaseous medium in a conduit includes a flap valve pivotably mounted in the conduit and biased by a spring toward its open position and by the pressure of the gaseous medium flowing through the conduit toward its closing position. A rod-shaped member is pivotally mounted on one section of the flap valve, and a sleeve-shaped member is pivotally mounted on a plate-shaped element rigid with the conduit and extending axially thereof downstream of the flap valve. The sleeve-shaped member has a passage therein in which the rod-shaped member is received with play so that, upon rapid movement of the rod-shaped member in the passage, the sleeve-shaped member is entrained by friction on pivots, thus seizing the rod-shaped member. In this manner, the flap valve is prevented from fluttering, while its responsiveness to gradual pressure changes of the gaseous medium is unaffected.

Abstract: ABSTRACT OF THE DISCLOSURE A commodity dryer for removing or providing moisture and controlling atmosphere which surrounds stored commodities such as grain is provided which reduces the growth of bacteria, fungus and minimizes other deleterious conditions encountered such as in the storage of moist commodities which generally render them unfit for subse-quent consumption.  The commodity dryer maintains the in-tegrity of stored commodities by creating a controlled atmosphere conducive to the removal or the addition of water by capillary action from the pores of the commodity and for controlling the moisture and temperature around the skin of the grain to achieve optimum storage condi-tions for the specific commodity stored.  The commodity dryer achieves it advantages by recycling, monitoring and modifying the air as it cycles through the commodity storage bin by introducing dried air from the top of the commodity bin down through the commodity contained therein and back to an evaporator heat exchanger coil for the re-moval of moisture and then back to a condenser heat ex-changer coil to pick up heat for subsequent recirculation back to the top of the bin and back through the commodity.
