Abstract: Abstract of the Disclosure A fluid operated actuator for activating the clutch mechanism of a clutch-operated cable drum is disclosed wherein the clutch mechanism rotates with a shaft upon which the cable drum is jouralled and is operable to engage the cable drum for rotation with the shaft by axially displacing a portion of the clutch mechanism. The actuator, which is cylindrical in geometry and includes a cylindrical bore, is engaged to the end of the rotating shaft and being adjacent to the axially displacing portion of the clutch mechanism. A piston is slidably retained in the actuator bore and a number of circumferentially spaced apart thrust pins that are slidably retained in openings of the actuator endwall structurally link the piston with an annular plate that is positioned between the actuator endwall and the axially displaceable portion of the clutch. As fluid pressure is introduced into the cylindrical bore through a rotary fluid coupling in the opposite endwall of the actuator, the piston forces the thrust pins and annular plate against the clutch mechanism to axially displaced the clutch mechanism and engage the cable drum to the rotatable shaft.

Abstract: ABSTRACT   A method and apparatus are described.  In the method, a thermosetting molding material, such as a phenolic molding composition, is initially heated and plasticized.  The plasticized mass is passed through an injection nozzle and then through a temperature-controlled manifold maintained at a temperature sufficiently high to keep the mass in a plasticized condition but sufficiently low to avoid any substantial curing or setting-up of the mass.  In the manifold the plasticized stream is divided into two or more smaller streams which are passed through a plurality of outlets into a plurality of partially open, heated molds.  The mold cavities are maintained at temperatures sufficiently high to cure the thermosetting molding material.  The feed stream is interrupted, and the molds are then completely closed to press and cure the plasticized material enclosed within them.  The cured, finished article is removed from the mold and the process repeated.  In the apparatus, means are provided for accomplishing the foregoing process.

Abstract: PROCESS FOR REMOVAL OF CARBONYL SULFIDE IN LIQUIFIED HYDROCARBON GASES     WITH ABSORPTION OF ACID GASES     Abstract Liquified hydrocarbon gases containing at least carbonyl sulfide as an impurity are purified by intimately mixing the liquified hydrocarbon gas with an aqueous absorbent for hydrogen sulfide in a hydrolysis zone maintained at a temperature and a pressure sufficient to maintain the liquified hydrocarbon gas in the liquid state and hydrolyze the carbonyl sulfide to hydrogen sulfide and carbon dioxide. The liquified hydrocarbon gas containing at least a portion of the formed carbonyl sulfide and carbon dioxide is separated from the liquid absorbent and passed to an absorption zone where it is contacted with a liquid hydrogen sulfide absorbent where at least the formed hydrogen sulfide is separated from the liquified petroleum gas.  A stage of absorption of at least hydrogen sulfide may proceed mixing of the liquified hydrocarbon gas with the absorbent in the hydrolysis reaction zone.  The absorbent employed does not combine irreversibly with carbonyl sulfide, hydrogen sulfide, and carbon dioxide, and preferably is an aqueous solution of diethanolamine.
