Abstract: COAL-OIL-WATER FUEL MIXTURE     ABSTRACT           A coal-oil-water fuel mixture is stabilized by adding thereto an effective amount of a suitable water-soluble, hydrophilic macromolecular agent, acting in many cases as a water thickening agent increasing the viscosity of the mixture.          Suitable such agents include high molecular weight synthetic polyamides, proteins, peptides and hydroxyalkyl polysaccharides.  Inorganic salts having high ionic activity coefficients, such as inorganic calcium salts, have also been found to be effective in the stabilization of such a fuel mixture.

Abstract: 49,027 ABSTRACT OF THE DISCLOSURE A regulated DC power supply has a converter hav-ing a plurality of switches which, upon proper regulation of their conduction, rectify an AC current.  The converter produces a current feedback signal.  A reference generator produces a plurality of adjustable reference signals each representative of one value of a load current and produces a predetermined, standby, reference signal representative of a standby load current.  One of the adjustable refer-ence signals, the standby reference signal, and the cur-rent feedback signal are added to produce a control sig-nal.  The control signal is compared to a signal repre-sentative of the AC source voltage.  Firing signals, used to regulate the conduction of the switches, are produced in response to the existence of a predetermined relation-ship therebetween.   In the event that all of the adjust-able reference signals have a value of zero for a prede-termined period of time, the firing signals will be inhib-ited from regulating the conduction of the switches.

Abstract: ABSTRACT      A liquid cooling tower has liquid distribution nozzles that spray liquid to be cooled away from the sides of the fill chamber.  The spray pattern is restricted to less than about 180°.  This prevents liquid from being sprayed out of or on to the tower or from being carried out of or on to the tower by the air flow.  The nozzles have a single large liquid discharge opening so that solid objects that flow in with the liquid will not clog them.

Abstract: ABSTRACT           The invention relates to the application of coolant onto the surface of an electromagnetic DC cast ingot or billet where two coolant streams are directed to the solidified or partially solidified metal so that the two streams intersect a short distance away from the metal surface.  By controlling the velocity and/or volume of one or both coolant streams, the point of impact on the metal surface can be brought closer to the discharge end of the inductor and thereby increase cooling rates.  In this manner the excursions of molten metal which form the icicle-like appendages on EM cast ingot or billet can be effect-ively eliminated.  When the end of the ingot or billet passes the area of coolant impact and the risk of such excursions is slight, the point of coolant impact can be lowered to a more conventional level for the remainder of the cast.

Abstract: VIBRATORY STORAGE PILE DISCHARGER MEANS               ABSTRACT OF THE DISCLOSURE   The invention provides improved vibratory storage pile discharger means for promoting the downward flow of material from a storage pile of a flowable material, such as coal, limestone, woodchips, sulphur and the like, through an opening in a generally horizontal surface on which the pile is supported and into another area located beneath that pile-supported surface.  Basically, the improved means provided by the present invention comprises: (a) an inverted hollow frustoconical conduit member generally vertically arranged within the opening in the pile-supporting surface with its long central axis concentri-cally aligned with that of the opening and having its wider upper inlet end supported by the pile-supporting surface through resilient means and also having its narrower lower outlet end extending through the opening and into an area located therebeneath;  (b) an upright conical member mounted generally vertically within the wider upper inlet end of the hollow frustoconical conduit member with its base being radially spaced apart from the interior walls there-of and having its long central axis concentrically aligned with those of the opening in the pile-supporting surface and the inverted hollow frustoconical conduit member and also having its apex extending above the the uppermost edge of the inverted hollow frustoconical conduit member; and (c) drive means connected to the inverted hollow frustoconical conduit member for imparting vibratory movement to it and the upright conical member mounted therein with respect to the pile-supporting surface and the opening therethrough to trans-mit vibratory impulses to the pile and thus promote downward flow of material from the pile through said conduit member and into the area located beneath the pile-supporting surface.  Preferably, the upright conical member also has attached to it a plurality of circumferentially spaced apart ribs which pro-ject outwardly and downwardly from its upper surface and the uppermost edge of the inverted hollow frustoconical conduit member is absent of an upright frustoconical drawdown skirt around its periphery.
