Abstract: ABSTRACT OF THE DISCLOSURE       Oil-soluble, derivatized ethylene copolymers derived from about 2 to 98 wt.% etyhlene, and one or more C3 to C28 alpha-olefins, e.g. propylene, which are grafted, preferably solution-grafted under an inert atmosphere and at elevated temperatures and in the presence of a high-temperature decomposable free-radical initiator, with an ethylenically-unsaturated dicarboxylic acid material and thereafter firstly reacted with from 0.1 to 0.9 molar equivalents of a t-amino-amine compound containing only one primary amino group to form imido groups and then secondly reacted with from 0.1 to 0.9 molar equivalents of a .alpha.,.omega. primary diamine having at least two primary amino, groups, e.g. a poly(alkylene amine) such as diethylene triamine, to form carboxyl-grafted polymeric imide, usually succinimide, intermediate and thirdly reacted with an anhydride of a C1-C30 hydrocarbon sub-stituted acid, preferably acetic anhydride, to yield an oil-soluble stable amidederivative of said polyamine whereby oil solutions of said amide derivative are characterized by minimal viscosity change over an extended period of time.  Useful number average molecular weight (?n) of said copolymers range from about 700 to 500,000 however, if the molecular weight is from 10,000 to 500,000 then these copolymers are multifunctional viscosity index improvers of enhanced sludge dispersant activity. It is preferred to treat these derivatized copolymers with oil-soluble hydrocarbyl substituted acids, preferably with long chain alkylaryl sulfonic acids with an average side chain carbon number of about 20-40, to yield haze-free hydrocarbon concentrate useful as an additive solution for lubricating oils.

Abstract: Abstract A data processing system or printer subsystem is provided with facilities for detecting emitter changes that have occurred during operating intervals. In a typical operation, a microprocessor initiates a command to a moving assembly, such as a forms feed assembly, then once the operation is initiated the microprocessor transfers to other program responsi-bilities, meanwhile periodically checking the status of the forms feed assembly.  The forms feed assembly supplies emitter signals to the processor which are utilized by the microprocessor to determine whether or not any emitter changes have occurred during the intervals between the checking operations.  The microprocessor has a stored data table and logic responsive to emitter signal conditions that had previously occurred (WAS) and that is further responsive to emitter signals that are presently occurring (IS) to supply an output in numbers of emitters indicative of both the extent and direction of movement of the assembly during the intervening interval.

Abstract: GYPSUM FIRE BARRIER FOR CABLE FIRES            Abstract of the Disclosure Electrical power, instrument and communication cables constructed with combustible coverings can provide a pathway by which fire might spread.  Cable fires within a room or compartment can the arrested by the construction of a properly designed "fire break" placed periodically along a cable run: and cable fire spread between rooms can be arrested by a properly placed "fire stop". Cable runs generally include a cable tray or raceway to contain the cables. An effective fire barrier, e. g., "fire break" or "fire stop" may be constructed in such a cable tray or raceway by filling a portion of the tray or raceway with a gypsum composition comprising gypsum plaster, an inert filler mixture of diatomaceous earth and lightweight expanded aggregate, and very small amounts of glycerin, boric acid and a corrosion inhibitor such as a boron nitride, boron nitrile or mixture of such boron compounds.  The fire barrier is formed by placing in a portion of the cable tray/raceway an aqueous slurry of the plaster composition as described above, slurried with water in amounts of about 10 pounds of the plaster composition and 14-16 pounds of water to form a "pseudo-plastic" mass, and filling all of the voids around and beneath cables therein by applying force to the cable tray/raceway, e.g., as by hammering with a rubber mallet.

Abstract: A B S T R A C T The invention relates to a method for enriching liquids with gases, more particularly to the enrichment of water with CO2 gas for the production of beverages, of the type in which the liquid is cooled and intensive contact between gas and liquid is obtained by introducing one of the two media into the other.  In order to achieve rapid and intensive enrichment at low pressure, continuous mixing of gas with enriched liquid is effected by a closed circuit. It is possible either to pump gas from the gas-cushion formed above the liquid and to introduce it below the level of the enriched liquid, or to pump a part of the enriched liquid into the gas-cushion formed above the enriched liquid.

Abstract: Dynamically Reevaluated Elevator Call Assignments Abstract An elevator control system employs a microprocessor-based group controller which com-municates with the cars of the elevator system to determine the condition of the cars, and responds to hall calls registered at a plurality of landings in the building serviced by the cars under control of the group controller, on a cyclic basis which recurs several times per second, to assign every unanswered hall call to a car deemed best suited for response to that call, in each cycle, based upon the information provided by the car to the group controller within that cycle of operation. In any cycle in which a call is assigned to a car other than a car to which the call had previously been assigned, the assignment of the call to the previous car is nullified.  At the end of each cycle, any car which indicates that its committable position coincides with the floor of a hall call which has been assigned to it will receive a stop command.  In the assignment of calls to cars, pref-erence is given to any car which previously had a call, although the preference is relative and not absolute.  Exemplary elevator apparatus, signal processing apparatus, and logic flow diagrams are disclosed to illustrate the specific manner of assigning calls to cars on a continuously updated basis, and to illustrate the environment in which the invention may be practiced.

Electrostatic applicators are mounted to direct the coating into a substantially closed chamber at a portion of the elongated object passing therethrough.  To substantially eliminate the explosive hazard occasioned by the use of an organic solvent-based coating material in the presence of electrical equipment, a combustibly inert atmosphere is maintained in the chamber and in an exhaust system leading therefrom.  To maintain the electrostatic field, the coating chamber and associated coating equipment must be electrically isolated from ground.
