A plurality of workers is configured for parallel processing of deduplicated data entities in a plurality of chunks. The deduplicated data processing rate is regulated using a rate control mechanism. The rate control mechanism incorporates a debt/credit algorithm specifying which of the plurality of workers processing the deduplicated data entities must wait for each of a plurality of calculated required sleep times. The rate control mechanism is adapted to limit a data flow rate based on a penalty acquired during a last processing of one of the plurality of chunks in a retroactive manner, and further adapted to operate on at least one vector representation of at least one limit specification to accommodate a variety of available dimensions corresponding to the at least one limit specification.

The present application relates to novel monodisperse, gel-type or macroporous picolylamine resins which are based on at least one monovinylaromatic compound and at least one polyvinylaromatic compound and/or a (meth)acrylic compound and contain tertiary nitrogen atoms in structures of the general formula (I)
A process for the purification of organic isocyanates or isocyanate mixtures in which the amount of chlorine compound(s) present is reduced by mixing the isocyanate(s) or isocyanate mixtures with a gel-type or macroporous, anion-exchanging organic material having tertiary and/or quaternary amino groups. The process renders possible a purification of the isocyanates from chlorine-containing compounds which is milder than in conventional processes and is therefore particularly suitable for temperature-sensitive isocyanates.
A dressing unit for advancing and retracting a spindle, having a diamond roll rotatably mounted thereon, wherein advancement of the spindle brings the diamond roll into contact with a grinding wheel for dressing the grinding wheel. The dressing unit comprises an outer ram mounted within a housing, an inner ram telescopically disposed within the outer ram, means for advancing and retracting the outer ram to a positive stop, and means independent of the advancing and retracting means for incrementally moving the inner ram from an inner position to an extended position. The inner ram is connected to the spindle to advance the spindle to thereby bring the mounted diamond wheel into contact with the grinding wheel.
An element for exploding magnetic mines comprising a permanent magnet arranged for driven engagement with a ground surface thereby providing rotation thereof, the permanent magnet being disposed at a distance in front of a vehicle to be protected from mines, whereby action of the permanent magnet provides premature detonation of mines in the vicinity thereof at a safe distance in front of the vehicle.
A new method of diazotization consists in using as the diazotizing agent in an aqueous, aqueous organic or organic medium the system comprising salt of nitrous acid+acid insoluble in the reaction medium, in particular organic or inorganic cation exchangers having acid groups. The diazonium salt solutions thus prepared are immediately reacted with coupling components to give azo dyestuffs, the insoluble acid and/or its salt being separated off before or after the coupling.
Mine clearing apparatus for attachment to a vehicle and comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation; apparatus mounted onto the frame for raising and shunting aside mines including a plow section, the plow section defining a plurality of plow teeth which, in operation, extend below the ground surface, and conveyer apparatus extending along the length of the plow section and adapted to convey the contents of the earth raised by the plow section to one side of the vehicle.
Cyclic N-vinylacylamines are prepared by heating carbonic acid esters of cyclic N-2-hydroxyethylacylamines in the presence of a catalytic amount of alkali or alkaline earth metal compound having an alkaline reaction and subsequently distilling the reaction mixture.;Cyclic N-vinylacylamines are valuable precursors for preparing plant
Substituted ethyleneureas are prepared by reacting appropriate .beta.-hydroxyethylureas with alkyl carbonates in the presence of catalysts at an elevated temperature.;Substituted ethyleneureas are used, inter alia, as polymerization and
The present invention relates to a process for preparing novel, monodisperse crosslinked bead polymers having thiourea groups and their use for adsorbing metal compounds, in particular heavy metal compounds or noble metal compounds.
