Abstract: PROCESS FOR TREATING SOUR PETROLEUM DISTILLATES     ABSTRACT         A process for treating a mercaptan-containing sour petroleum distillate is disclosed.  A sour petroleum distillate, in admixture with an oxidizing agent, is passed into contact with a catalytic composite in the presence of an alkaline reagent, said catalytic composite comprising a metal chelate mercaptan oxidation catalyst and a quaternary ammonium compound impregnated on a solid adsorbent support disposed as a fixed bed in a first treating zone.  The ef-fluent  from said first zone, in admixture with an oxidizing agent, is then passed into contact with a catalytic composite in the presence of an alkaline reagent, said catalytic com-posite comprising a metal chelate mercaptan oxidation cata-lyst impregnated on a solid adsorbent support disposed as a fixed bed in a second treating zone.  A petroleum distillate, substantially free of mercaptan sulfur, is recovered from the second treating zone.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for controlling the burning of a solid fuel furnace is disclosed. In a furnace having a burning chamber, a fuel supply mechanism in the form of a rotating grate, a fuel discharge mechanism in the form of a rotating grate located adjacent the rotating grate of the fuel supply mechanism and at least one air blower, the present invention provides a control mechanism for controlling the operation of the fuel supply and discharge mechanism as well as the blowers in such a manner that fuel is supplied and discharged in an optimum manner.  The control mechanism senses the temperature of the combustion gases and the temperature of the load being heated by the furnace. If the temperature of the load is below a predetermined level and a first time period T1 has not passed since a preceding fuel supply and discharge, the fans are activated but a fuel supply and discharge cycle is not. If the time of the sensing of the low load temperature is below the time T1 and a later predetermined time T2, then the low load temperature signal activates the fuel supply and discharge cycle. If a time of at least T2 has passed since the last fuel supply and discharge cycle t then a subsequent fuel supply and discharge cycle is activated whether the load temperature is low or not.

Abstract: ABSTRACT OF THE DISCLOSURE A method is provided for preparing a green composition having a pre-determined ratio of water to a powder of hydraulic substance wherein the hy-draulic substance is admixed with water and a fine aggregate. The method com-prises the following steps: preparing particles of the fine aggregate in which water is uniformly deposited on the entire surface thereof so as to exclude air voids, by adding a primary water to the particles in an amount necessary to optimize the percentage of the surface water on the particles; incorporating a powder of the hydraulic substance with the particles thus absorbing the powder of hydraulic substance with the surface of the particles to form shells about the particles, the shells having a smaller ratio of water to powder than the pre-determined ratio of the green composition; adding a secondary water to the shelled particles in an amount providing the remaining portion of the neces-sary water; and kneading the resulting mixture. After incorporating gravel, thereinto, the resulting green concrete can be moulded or blasted. The green concrete can be readily conveyed to a working station for constructing tunnels or buildings or the like. Since stable shells of cement are formed to sur-round sand particles, the green mortar is free from any segregation, precipi-tation and bleeding and has excellent fluidity so that it can safely be stored in a tank over a substantial interval of time or can be conveyed to a working station which is remote a considerable distance from a station at which O   the green mortar or concrete is prepared.

Abstract: VENT FOR A CLOTHES DRYER     ABSTRACT OF THE DISCLOSURE     An energy saving vent is provided for selectively directing hot, moist exhaust air from a clothes dryer either through a downstream vent sleeve to the outdoors, or through a vent port to the indoors.  The vent includes four major components principally molded from a synthetic plastic resin, the components being: an open sided housing; a closure panel for closing one open side of the housing; a valve member within the housing for selectively directing air through the housing in alternate paths; and a filter screen assembly for another open side of the housing.  The selectively swingable valve carries a pressure relief means adapted to provide for passage therepast of pressurized exhaust gas when the valve is in its position to direct air flow indoors, and in the event that the flow of air indoors is blocked by the filter screen being clogged.  The preferred filter screen is a truncated, basket-like, member that is carried on a frame which is removably carried in a slide channel defined on the housing. The valve member is formed integral with an elongated pivot shaft.  Op-posed portions of the housing are formed to provide bearings within which the valve's pivot shaft is selectively pivotable, and axial slidable.  Means are provided for latching the valve in each of its alternate positions.
