Abstract: ABSTRACT           WORM REDUCTION GEAR WITH CONNECTIONS           A short summary of the invention The worm reduction gear according to the invention is designed without any screws or bolts.  It is equipped for bearing and driving machines and for carrying loads.  It has a wide range of applications - a wide variety of driven machines and parts can be attached to it.  It can be manufac-tured on automatic machines because all its supporting and bearing parts are circular and because the number of the component ports has been brought to a minimum.  The entire gear has only half the weight of other existing gear types. It is simple to assemble and disassemble; these two opera-tions can also be done by robot.  A great advantage of this reduction gear is the fact that the gear cannot be assembled unsatisfactorily: once assembled, it is well assembled and well sealed.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for effecting enhanced contact between two intermixed immiscible liquids of different electrical conductivities comprises applying both intense mechanical agitation in a primary zone and, in an immediately adjacent secondary zone, a varying electrostatic field, in order to effect rapid change of their liquid-liquid interfaces but maintaining droplet size of a desirably high magnitude at least outside the primary zone.  The primary zone is shrouded from the secondary zone so as to shroud the dispersed phase from the effect of the electro-static field while the dispersed phase is subjected to intense mechanical agitation in the primary zone.  The method may be applied to, for instance, liquid-liquid extraction. Apparatus is also described.

Title: Time-controlled processes for agglomerating coal
Inventor: KELLER DOUGLAS V JR
IPC: B01D21/01
Filed: 1986-11-21
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE           Methods of recovering agglomerated particles of coal from a composite of coal and mineral matter.  If necessary to reach an appropriate top size, the raw coal can be ground.  In any event the raw coal is mixed with an appropriate carrier to form an aqueous slurry.  The raw coal may then be comminuted in the aqueous slurry until resolved into separate, particulate phases of coal and mineral matter although this step is unnecessary if the coal has a top size of not more than 0.6 mm and if an ultrapure product coal is not required.  Next, an agglomerant is mixed with the slurry; an additive is incorporated into the slurry to control the agglomeration time and/or water content of the product coal and/or to insure that the coal particles will agglomerate; and the slurry is agitated until the coal particles have separated from the aqueous carrier and the mineral matter dispersed in the carrier and coalesced into agglomerates which are recovered from the slurry.

Date Feb. 9, 1989.A surface deposition or surface treatment reactor, in particular for chemical vapor deposition, has an annular reaction chamber (CR) delimited by two tubular walls (1, 2), in particular of quartz. A first hearing unit is arranged inside the tubular wall (1) and a second heating unit is arranged around the outer tubular wall (2). Said units are controlled by heat-regulating means in order to ensure a predetermined longitudinal temperature profile in the reaction chamber (CR). The gas phase is distributed at a longitudinal end of the chamber (CR) through distribution ducts (18) and removed by suction at the other end through pumping ducts (20). The substrates (S), which may be very numerous, are swept simultaneously by the gas phase and the perfect control of the temperature distribution and of the flow makes it possible to obtain a uniform treatment of the desired type which is identical for all the substrates.
