Abstract: ABSTRACT OF THE DISCLOSURE             Novel process for removing polymer from aqueous absorbent solutions used to contact organic gas-containing gas streams comprising the steps of adjusting the polymer-containing aqueous absorbent solutions to a pH of not more than about 8.5, preferably not more than about 7.5, for example, about 6.0 to about 8.5, preferably about 7.0 to about 7.5, and removing the polymer from the resulting solutions by decantation and/or filtration.          The novel process is particularly applicable to the system of removing acid gas from hydrocarbon-containing feed gases which contain one or more polymerizable components wherein the feed gas is contacted with an aqueous absorbent solution which absorbs the acid gas and, thereafter, the absorbent solution is stripped to rid it of said acid gas. The adjustment of pH can be accomplished by increasing the acid gas loading in the aqueous absorbent or by adding on acid, preferably one which will not form a heat stable salt with the absorbent. The pH adjustment, e.g., acidification, and filtration can be performed on the total mainstream or a portion thereof, i.e., a sidestream, before it is stripped.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention discloses a hydraulically operated hoisting apparatus for a ship for picking floating objects up out of the sea.  It is characterized by an arm fixed on the deck of a ship so as to articulate about a horizontal axis with the end of the arm projecting freely over the side of the ship.  The apparatus comprises means for picking up objects and coupling to a hydraulic cylinder which is connected to a source of liquid.  The source of liquid has a liquid store which is acted on by gas pressure and is connected to the hydraulic cylinder via a valve which is opened by a member which senses the proximity of an object to be picked up to the end of the arm.  The apparatus prevents the hoisted object from col-liding with the surface of the sea by hoisting the object suddenly and rapidly clear of the danger area above the surface of the sea.  The power peaks required to accomplish this are supplied by the liquid store.

Abstract: Abstract The present invention is concerned with a new and chemically unique one-pot process for the preparation of thiazolidin-4-one-acetic acid derivatives of the general formula:-                              (I) wherein R1 is a lower alkyl radical.  In this new process, the 5-bromo derivatives of the corresponding carboxylic acid alkyl esters are prepared by reaction with elementary bromine in a solvent of low polarity.  The hydrogen bromide thereby formed splits the ester bond at elevated temper-atures, whereupon the 5-bromo derivatives of the free acid can be directly reacted in situ with piperidine.

Abstract: ABSTRACT OF THE DISCLOSURE A polymer parison to be blow molded into a container configuration is disclosed, which includes a reduced diameter neck and a tapered wall dis-posed between the neck and a greater diameter body portion of the container. The body portion is shaped to permit a sufficient amount of stretch to be imparted to the tapered wall forming portion of the parison which has a less-stretching tendency during the blow molding operation.  Polyethylene terephthalate exhibits greatly improved characteristics and enhanced durability when it is biaxially stretched beyond a certain fixed level.  The parison is formed by injection molding such that when the parison is placed in the mold cavity, the tapered wall forming portion is at a longer distance away from the cavity wall so as to achieve a sufficient amount of stretch, as compared with the body forming portion of the parison, when it is blown to assume the con-tour of the mold.

Abstract: VEHICULAR SINGLE SHAFT GAS TURBINE ENGINE POWER SYSTEM        Abstract of the Disclosure A vehicular gas turbine engine power system includes an engine, an automatic clutch, a service clutch and an infinitely variable transmission coupled successively along a power train.          A vehicle control system controls engine speed, transmission ratio and automatic clutch engagement in response to operator selected ground speed and engine speed commands as well as other vehicle conditions.  The vehicle control system operates in a manual mode to maintain engine speed as commanded by an operator or in an automatic mode to maintain an engine speed which will minimize fuel consumption.  The transmission ratio is controlled for fixed rate vehicle acceleration towards a commanded speed if sufficient power is available.  Otherwise ground speed is cut back to match required power with available power.  However, ground speed cutback is limited as a safety feature and disengage-ment of the automatic clutch prevents engine stall when the engine becomes overloaded.

Abstract: ABSTRACT           A control device for an automatic door operator is a highly compact assembly employing a plurality of disc-type springs confined within a housing and cooperable with a plunger; the assembly being fixed to one of a pair of adjacently disposed rotatable gears in the drive train of an automatic electro-mechanical door operating mechanism.          The involved gears are disposed in overlapping relationship and the stop assembly of this invention is engageable with the periphery of one of the gears in response to partial rotation of the other whereby to limit their relative ro-tation and limit door opening operation.  The disc-springs are capable of producing impact resistance of a relatively high value and of sufficient magnitude to protect the mechanical drive train from expected overload forces.          Adaptation of the disc-spring concept for the door stop permits an extremely compact stop device capable of being mounted within the limited confines of a header mounted or under-the-floor mounted housing for the operator mech-anism, thereby satisfying desired esthetic requirements while avoiding operational defects prevalent with hereto-fore known hydraulic or pneumatic door stops.
