Abstract: ABSTRACT OF THE DISCLOSURE         An ignition system for internal combustion engines in which a capacitor is charged at each one-polarity half-cycle of the output of a magneto generator and then the capacitor is discharged through a thyristor and a primary coil of an ignition coil when the thyristor is turned on.  To turn on the thyristor, a gate-cathode current is supplied through a semiconductor switching element from an auxiliary capacitor which is charged by a timing generator which generates an output prior to only a predetermined ignition time.  Although the semiconductor switching element is turned on by an ignition signal generating means, for example, a trans-former, when the transformer produces an ignition signal at each the other-polarity half-cycle of the magneto generator output, the gate-cathode current is supplied to the thyristor only when the auxiliary capacitor has been charged by the timing generator.

Abstract: A PROCESS FOR REDUCING COPPER-BEARING MATERIALS     ABSTRACT     Copper is recovered from copper-bearing materials such as copper chlorides, copper oxides and copper oxychlorides by intimately contacting the finely divided solid copper salts with hydrogen at a temperature greater than the melting point of elemental copper.   Turbulent conditions preferably in the form of a cyclone are used to effect the necessary contact between the copper salts and the hydrogen.   Under these conditions, the copper salts are substantially instantaneously reduced to liquid elemental copper.

Chambers For:  DRYING PROCESS AND APPARATUS        FOR ACCOMPLISHING THE SAME                Abstract of the Disclosure There is provided a process and apparatus for drying wet solid material.  The process comprises introducing wet solid material into a dryer bringing the material into contact with one side of a plurality of heated surfaces located in the dryer and vaporizing liquid contained in the wet solid material.  The vaporized liquid is withdrawn from the dryer and compressed to a pressure greater than the pressure in the dryer and then returned to the other side of the plurality of heated surfaces where, upon condensation, the latent heat energy is released therefrom and is used to vaporize liquid contained in wet solid material on the opposite side of the heated surfaces and withdrawing the condensate from the heated surfaces and substantially dried solids from the dryer.            The drying apparatus provided comprises a housing having entrance and exit openings and means for delivering ma-terial to be dried into and dried material from the housing located in the opening  and closing and isolating the interior of the dryer from the outside atmosphere.  A plurality of hollow heat exchange means are disposed in the interior or the dryer housing and are connected to an external heat source and to the atmosphere,  In addition, compressor means are connected to the housing in the vicinity of the entrance opening and to the hol-low heat exchange means, the compressor means operating at posi-tive pressure with respect to the pressure in the housing so that vaporized liquid is withdrawn from the housing or compressed and then led to the hollow heat exchange means where it is condensed, giving up its latent heat energy and thus vaporizing the liquid in wet solid material on the opposite surfaces of the hollow heat exchange means.

Abstract: DENTAL RETAINING SPLINT            ABSTRACT OF THE DISCLOSURE     A dental retaining splint is disclosed including a bar-like body member having preferably two tubular members extending perpendicularly therefrom, where the tubular members have axial openings extending therethrough.  The body member has an H-shaped configuration with the front and rear walls being serpentined to define sections therein.  These sections can be removed, such as by cutting, to provide a shorter splint. In use, the splint is first temporarily held in a channel formed in adjacent teeth, where the tubular members function as guides for a drill to form pilot holes in the teeth.  The splint is then removed, and the pilot holes function as lead holes for the formation of enlarged bores to receive the tubu-lar members therein for retaining the adjacent teeth in a fixed position.  The splint is then replaced so that the tubu-lar members are disposed in the bores formed therefor.  An inlay fills in the channel and covers the splint in the final procedure step.  Accordingly, the splint structure can be formed wider, longer, and include additional tubular members to fulfill particular dental requirements.

Conflicting memory requests involving addresses recognized by more than one of the supra memory categories, when enabled, are presented to a predetermined hierarchy of memory precedences for resolu-tion thereof.  Each of the enumerated memory categories of the auxiliary ROM memory system may be operative to have its population incremented or decremented without invalidating the above hierarchy of addressing.
