Abstract: Solid non-dusty, porous dyestuff-foams are described of any desired shape and size containing at least one dyestuff, a foaming agent and optionally bonding agents and/or further additives.These foams are useful for preparing dye liquors or printing pastes by sprinkling said foams into water or organic solvents.

Abstract: A mixture of a holding oil such as mineral oil, a saturating oil such as mineral seal oil, and perchloroethylene such as perchloroethylene with amyl acetate and a dye as optional additives.

Abstract: A nuclear reactor cooling system in which the cooling system for cooling a fuel element well is combined with the after-cooling system used at shutdown, and the emergency cooling system resulting in a substantial reduction in the number of cooling system elements required thereby reducing the overall cost of the cooling system. The fuel element well contains an excess of coolant which may then be used, in case of a break in the primary cooling circuit to supply emergency coolant to the reactor. In addition the pump and some of the lines of the fuel well cooling system are shared with the after cooling system resulting in a further reduction of components.

Abstract: Molten fuel produced in a core overheating accident is caught by a molten core retention assembly consisting of a horizontal baffle plate having a plurality of openings therein, heat exchange tubes having flow holes near the top thereof mounted in the openings, and a cylindrical, imperforate baffle attached to the plate and surrounding the tubes. The baffle assembly is supported from the core support plate of the reactor by a plurality of hanger rods which are welded to radial beams passing under the baffle plate and intermittently welded thereto. Preferably the upper end of the cylindrical baffle terminates in an outwardly facing lip to which are welded a plurality of bearings having slots therein adapted to accept the hanger rods.

Abstract: A process for treating domestic, municipal or industrial liquid waste to reduce B.O.D. of the waste comprising adding a sufficient amount of an acid formula and a sufficient amount of an alkaline formula to said waste, to thereby cause evolution of heat and cause flocculation of solids, and separating the resulting solids from the liquid. The novel acid formula and alkaline formula are disclosed. Liquid wastes treated by the process of this invention can be safely discharged into rivers, lakes and streams. In addition the process is extremely efficient since flocculation is rapid, and in many instances starts immediately upon the addition of either formula to the liquid waste.

Abstract: Pigmented detergents having improved shelf stability are provided by dispersing in liquid detergent a polymeric pigment made by an emulsion polymerization process comprising the steps of (1) emulsion polymerizing from about 0 to about 80 weight percent of total monomer in absence of emulsifier, (2) adding a nonionic surfactant, and (3) continuing emulsion polymerization of the remaining monomer charge.

Abstract: A cleaning composition in the form of a thixotropic paste which consists essentially of finely divided insoluble particulate matter, water, a petroleum distillate boiling from 150.degree. to 250.degree.C., a hydrocarbon or halogenated hydrocarbon liquid boiling from about 35.degree. to 75.degree.C., and an emulsifying surfactant.

Abstract: Reductive bleaching agents which contain alkali metal sulfites and zinc oxide or soluble zinc salts.

Abstract: A method for the preparation of a liquid concentrate solution containing 10 to 60 percent by weight water from which a metal cleaning solution may be prepared by dilution with additional water.The liquid concentrate was prepared from ferrous sulfate, an oxidant, an acid, a fluoride ion source and water. It may optionally contain ammonia and urea.

Abstract: A process for the restoration of the initial chemical lighting potential of a chemiluminescent lighting system. More particularly, a process for the restoration of the chemical lighting potential of a two component chemiluminescent lighting system.

Abstract: A non-aqueous cleaning composition consisting of volatile oil, alcohol and portland cement.

Abstract: Constant boiling binary admixtures are formed by 1,2-dichloro-1,1,2-trifluoroethane with trichlorofluoromethane, with diethyl ether, and with dichloromethane. A constant boiling ternary admixture is formed by 1,2-dichloro-1,1,2-trifluoroethane, diethyl ether, and 1,2-dibromo-1,1,2,2-tetrafluoroethane.

Abstract: A short-recoil operated automatic firearm is provided with a single locking ember for alternately (1) locking the breech bolt to the barrel while unlocking the barrel from the receiver, and (2) unlocking the breech bolt from the barrel while locking the barrel to the receiver. The locking member is a lever pivoted intermediate its ends on the barrel and comprising an arm engageable with an abutment (barrel buffer) on the receiver, an opposite arm having a notch engageable with a locking projection on the breech bolt, and an intermediate arm engageable by the bolt in its return movement to rotate the lever to bolt-locking (and barrel unlocking) position.

Abstract: This invention relates to azeotropic compositions of 1,2-dichloro-1-fluoroethane or of 1,2-dichloro-1,2-difluoroethane with certain alcohols, ethers, or ketones.

Abstract: A heat removal system for nuclear reactors serving as a supplement to an Emergency Core Cooling System (ECCS) during a Loss of Coolant Accident (LOCA) comprises a plurality of heat pipes having one end in heat transfer relationship with either the reactor pressure vessel, the core support grid structure or other in-core components and the opposite end located in heat transfer relationship with a heat exchanger having heat transfer fluid therein. The heat exchanger is located external to the pressure vessel whereby excessive core heat is transferred from the above reactor components and dissipated within the heat exchanger fluid.

Abstract: A means for rapidly shutting down or scramming a nuclear reactor, such as a liquid metal-cooled fast breeder reactor, and serves as a backup to the primary shutdown system. The control rod drive consists basically of an in-core assembly, a drive shaft and seal assembly, and a control drive mechanism. The control rod is driven into the core region of the reactor by gravity and hydraulic pressure forces supplied by the reactor coolant, thus assuring that common mode failures will not interfere with or prohibit scramming the reactor when necessary.
