Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a process for preparing oxidation pro-ducts of monoalkyl benzene compounds by means of a gas containing molecular oxygen.  This invention provides the possibility of processing the oxidation reaction mixture in a simple way into a number of desired products, such as, in particular, benzoic acid, benzaldehyde, and also benzyl benzoate and benzyl alcohol, in a pure state.  According to the invention, oxidation products of monoalkyl benzene compounds are prepared by oxidizing a monoalkyl benzene com-pound by means of a gas containing molecular oxygen, after which the oxidation reaction mixture is subjected to a carboxylic acid esterification reaction.

The alterable PROM storage comprises bulk PROM memory including a first PROM set that is mutually exclusive as to existing on-board ROM memory for addressably branching to code extensions and/or in-line code insertions, and/or a second PROM set that is mutually inclu-sive as to existent on-board and contigent ROM memory for decodably addressing large-scale code overlays thereto.  In addition, the alterable PROM storage comprises patch PROM for addressing, through multi-leveled decoding, small-scale code overlays to the on-board and contingent ROM memory for single in-line bit pattern alterations.  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.

Abstract: RADIO DETERMINATION USING SATELLITES TRANSMITTING TIMING SIGNALS    WITH CORRECTION BY ACTIVE RANGE MEASUREMENT                  Abstract of the Disclosure The time-of-arrival of timing signals transmitted by two satellites ismeasured relative to a crystal clock, and a approximate position fix is computedfor the ship or other object being located.  Because of clock error the positionfixes are displaced along a hyperbolic line of position.  A two-way active rangemeasurement through a third satellite or one timing signal satellite enables computation of an independently determined line of position, the true position fix being at its intersection with the hyperbolic line of position.  The clock error is corrected and the method of position fixing from two timing satellites is repeated until the clock drift exceeds acceptable limits.  A continuous navigation service and also position surveillance are realized.

Abstract: TITLE:  SLIPFORM APPARATUS FOR VERTICAL BORES   Abstract of the Disclosure A slipform apparatus is described for forming a continuous up-right monolithic lining within a preformed upright shaft.  The slipform is provided in three independently movable sections that may be lowered into the shaft.  Wet concrete is delivered to the sections and dispensed outwardly of the sections to form the lining.  The formed sections hold the wet concrete against the walls of the shaft and progressively form a cylindrical upright bore within the shaft.  As concrete is delivered to the slipform, the individual sections are moved in an "inchworm" effect in conjunction with an expansion mechanism to automatically lift itself upwardly within the shaft as the lining is being formed.  A steering mechanism is provided to enable selective angular movement of the slipform in a nonvertical plane.

Abstract: COMBINATION DISCHARGE-INCANDESCENT LAMP WITH THERMAL SWITCH CONTROL                               ABSTRACT         A combination lamp comprises a miniature arc tube, a standby filament and a thermal switch in a sealed vitreous envelope.  The switch is connected in series with the filament, and the arc tube and the filament have separate inleads for ex-ternal connections.  The switch is closed at room temperature, allowing the filament to light up immediately at a cold start and providing an instant-on feature.  During normal operation, heat and light radiated by the arc tube cause the switch to open and turn off the filament.  The small size of the arc tube favors a heat balance which allows the thermal switch to cool and re-close quickly in the event of a current interruption, thereby assuring lighting after an acceptably brief delay in the event of a hot restart.

Abstract: ABSTRACT OF THE DISCLOSURE     Epitaxial and diffusion-type planar diodes and solar cells utilize low-cost refined metallurgical silicon substrates having a substantially higher impurity content than conventional high-cost, high purity semiconductor grade silicon.  The epitaxial type products have an n-on-p-on-p substrate configuration, while the diffusion-type products have pentavalent impurities diffused therein to form a p-n junction in the low cost silicon substrate. One embodiment employs a multigrained refined metallurgi-cal silicon (RMS) prepared by precipitating essentially iron-free silicon platelets from a solution of metallurgi-cal grade silicon in molten aluminum, melting said refined platelets in contact with a silica slag and pulling sili-con boules from a melt of said refined metallurgical silicon (RMS).  By directionally solidifying the refined silicon-slag melt, a multigrained, directionally solidi-fied refined metallurgical silicon (DS/RMS) is obtained, with boules being pulled from a melt thereof for use as said low-cost substrate.  The DS/RMS may also be re-melted and directionally solidified a second time with the boules being pulled from said twice directionally-solidified material being a desirable, low-cost, single crystal material suitable for use as said substrate for planar diode and solar cell applications.
