Abstract: ABSTRACT OF THE DISCLOSURE:         An emergency lighting system that includes an electric discharge lamp and a DC - AC converter to sup-ply emergency power to the lamp upon failure of the AC line voltage. A battery is charged with a constant cur-rent from the AC supply voltage. A transistor switching device connects the battery to the converter when a sensing device senses the absence of the AC voltage.          A bias voltage that holds the switching device closed is derived from the battery via the emitter-collector path of the transistor switch. A given drop in the bat-tery voltage is sensed to open the switching device to prevent an excessive current drain on the battery. The presence of the AC voltage is sensed to hold the switch-ing device open and thereby prevent operation of the con-verter during normal operation of the lighting system.

Abstract: ELECTRONIC INTERNAL COMBUSTION ENGINE IGNITION   SPARK VACUUM AND SPEED ADVANCE SYSTEM WITH IGNITION DWELL TIME DIRECTLY PROPORTIONAL   TO ENGINE SPEED Abstract of the Disclosure:          A first and a second series of phase displaced leading and trailing electrical signal wave forms of a potential level proportional to engine speed are generated in timed relationship with the engine, the potential level of the first series being greater than that of the second series over the engine speed range, and an absolute pressure transducer produces an engine manifold absolute pressure electrical signal of a potential level proportional to engine manifold absolute pressure.  The engine manifold absolute pressure signal and the leading and trailing electrical wave form series are compared by respective comparator circuits. While the potential level of each of the leading electrical signal wave forms is equal to or greater than that of the engine manifold absolute pressure signal, the corresponding comparator circuit produces an output ignition dwell signal and when the potential level of each of the trailing elec-trical signal wave forms has increased to that of the engine manifold absolute pressure signal, the corresponding compara-tor circuit produces an output ignition signal.  An electronic ignition circuit is responsive to each of the ignition dwell signals for completing and to each of the ignition signals for interrupting, respectively, an energizing circuit for the primary winding of an associated ignition coil.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of constructing a board-type fence which is of sub-stantially identical appearance on both sides and which eliminates the need for nails in the construction thereof is provided.  The method com-prises constructing and assembling two different fence panels or modules by passing a pair of spaced parallel rods through a predetermined number of fence boards arranged in aligned side-to-side relation with the rod ends projecting outwardly from the sides of each panel.  The rods of both modules are spaced apart from each other at exactly the same distance.   However, the rods of one panel are spaced differently from a reference end of the panel from the rods of the other panel.  Each fence post is provided with two pairs of holes that are offset from each other, the holes of each set being spaced apart a distance exactly equal to the rod spacing of each panel.  Thus, with regard to a given fence post, the rod ends of a first panel will project into one pair of spaced holes in that fence post whereas the rod ends of the other fence panel will project inwardly into the other pair of spaced holes on the opposite side of the fence post.
