Abstract: PROCESS FOR PRODUCING A    COAL-WATER MIXTURE                    ABSTRACT OF THE DISCLOSURE         A process for producing a coal-water mixture includes forming dilatant coal particles in an aqueous coal feedstock mixture by treatment with ozone and classifying the coal feedstock to form first and second coal feed streams each comprised of differently-classified coal particles.  Separate surge vessels receive the coal particles to form separate feed streams.  The distribution of coal particles in a liquid medium forming each coal feed stream is determined and an electrical signal is delivered to a microprocessor fox controlling the portions of each stream which are mixed together in the presence of a dispersing agent to form a coal-water mixture. The coal-water mixture is comprised of at least 65% by weight coal particles, preferably 70%.  The coal content may be increased and flow properties of the coal-water mixture improved by removing a minus 2-micron particle fraction which is predominantly clay from feedstock and mixing a minus 2-micron fraction of coal particles with quantities of the first and second feed streams.

Abstract: ABSTRACT     An improvement in the dry vacuum cleaning of soft and hard surfaces in which vacuum only is applied to such surface, is characterised in that dry soil flowing away from such surface under the influence of vacuum is sprayed with liquid and deposited in a wetted condition in a liquid and soil-collecting vessel.   Also proposed is apparatus for cleaning hard and soft surfaces by simultaneous application thereto of liquid and vacuum using a tool and which is equipped with a conversion device to permit dry vacuum cleaning with entrainment of dry soil in the liquid for subsequent collection in a soil and liquid vessel.  The device          comprises a 2-way valve     by which liquid flowing through a first pipe     can be caused to flow alternatively to a head     of a tool, or, through at least one branch pipe     to a second pipe     or pipe insert      by which suction is applied to the head of the tool to entrain the dry soil flowing therein.          The branch pipe or pipes normally terminate in one or more spray nozzles and may be located at various different positions in the path of flow of the dry soil induced by vacuum.

Abstract: ABSTRACT OF THE DISCLOSURE         A feedthrough assembly for conduits basically has a wall formed with a throughgoing passage extending along an axis and having a radially inwardly directed wall surface.  At least one conduit passes axially through the passage.  A lining member in the passage receives at least one elastomeric adapter member having an outer surface complementarily radially outwardly engaging the wall surface and an inner surface snugly surround-ing and engaging the conduit.  A tightening unit has a tighten-ing member that presses the inner and outer surfaces of the adapter member sealingly against the respective conduit and wall surface.  One of the members is formed with at least one hollow chamber open radially inward at its inner surface and a mass of material generally fills the chamber.  This material reacts endogenetically and emits a fire-inhibiting gas when heated substantially.  The bulk of the fire-retarding material is provided in the adapter block.  The chamber is formed by an axially inwardly open pocket and a plug axially inwardly closing the pocket.  More particularly the block is then formed with a relatively narrow slot extending between its inner surface and the chamber.  The chamber opens via the slot radially at the inner surface.  The block can be formed with a plurality of such chambers and slots spaced angularly around the axis.  The inner surface of the block is formed with a radially inwardly open circumferential groove crossing and interconnecting the slots.

Abstract: ABSTRACT OF THE DISCLOSURE         A system adapted to readily cut intricate interior patterns from, as well as make simple cuts across, glass blanks of various thicknesses at increased speed by means of an ultra-high pressure abrasive fluid jet.  A highly collimated fluid stream or jet, into which abrasive particles are aspirated, is directed against the glass from a pressurized source.  For initial penetration of the glass within the interior of the blank, the pressurized source is maintained at a first pressure level, so that the glass is initially penetrated without fracturing or undue chipping at the point of penetration and whereby the abrasive fluid stream may be advanced along the desired path relative to the glass at a first speed such as to sever the glass.  After initial penetration by the abrasive jet the pressure level of the pressurized source of fluid is significantly increased, enabling the line speed of the fluid jet relative to the glass to be likewise significantly increased while still severing the glass and producing cut edges of high quality.

Abstract: ABSTRACT OF THE DISCLOSURE               The milking inflation is formed from an elastomeric material and includes a suction sleeve which is located inside the shell of a teat cup assembly and a milking tube portion which is located below the lower end of the shell.  An air vent is formed as an integral part of the milking tube portion at a location near the lower end of the shell.  The air vent includes an annular recess in the wall of the milking tube portion which defines an isolated area and includes a bottom having an annular web section of reduced thickness surrounding the isolated area and also an opening extending through the isolated area for admitting a metered amount of air into the milking tube portion.  The thinner, more flexible web section absorbs distortions caused by flexing of the milking tube portion during the milking operation, so that the air vent opening substantially retains its original shape and size during use.

Abstract: ABSTRACT OF THE DISCLOSURE:           Disclosed  is  a  process  of  preparation  of polyphenylene ethers from monohydric phenols, which possess alkyl substituents in the two ortho-positions and,  if desired, in the meta-position, but not in the para-position, by an oxidative coupling reaction with oxygen at from 15 to 50°C and under from 1 to 10 bar in the presence of a catalyst complex,  of a solvent and,  if required, of an activator.  In this process,the conversion of the phenols is carried out in two or more reaction zones.  Some or all of the solvent,     catalyst complex  phenols and where relevant,     activator are initially added to one of the reaction zones and are circulated in the other reaction zone and about 60-100% of the stoichiometric amount of oxygen required for the oxidative coupling is introduced into the first reaction zone and from 0 to about 40% of the said stoichiometric amount is introduced into the second reaction zone.  This process is interesting in that it makes it possible to carry out oxidative coupling of phenols with oxygen in a very economic and reliable manner, with very high space-time yields, formation of only a small amount of by-products,  and minimum emissions of gas and volatile components.

The power transformer is positioned in an enclosure that houses the magnetron and may also encase other electrical components such as the high voltage capacitor, the high voltage rectifier, an oven light, and a fuse board.  The blower is positioned outside the en-closure in a compartment housing the microwave oven controls, Air is drawn into the control compartment by the blower and then forced through a chute in the enclosure directly at the power transformer.  By static pressure differential, air exhausts the enclosure through a plurality of predetermined paths.  One path flows through the fins of the magnetron to an exhaust port.  Another path flows through perforations into the cavity to remove moisture and rotate a microwave antenna.

A work platform,  15  is  fixed  on  to  the  upper  mounting  for translational movement with the mountings. Inner beams 5, 6, 10 and 11 are slidable within the outer beams 2 and 3 and have attached to each of their ends yokes, which in turn have attached at each of their ends legs 8 and 13. The  legs  have  feet  9  and  14  and  are  telescopically extendible,  so that the weight of the vehicle can be supported alternately on each set of legs i.e. on legs 8 or legs 13. By causing all the inner beams to slide in the  outer beams  simultaneously whilst  the vehicle  is supported on one set of legs and then transferring the weight to the other set of legs and causing the inner beams to slide in the opposite direction, the vehicle can "walk". The work platform can move forward continuously. By rotating the upper and lower mountings relative to each other the vehicle  can be  steered  and caused  to travel in any direction.
