Abstract: COMPATIBLE AM STEREOPHONIC       RECEIVERS          Abstract of the Disclosure Compatible AM stereophonic receivers for reception of a radiant energy carrier wave modulated with two stereo related signals (L and R), each appearing as a respective first order single-sideband.  Receivers embodying the invention in general improve and optimize output stereo signal quality by quadrature demodulation of the carrier to derive the stereo difference (L-R) signal, together with in-phase detection of the stereo summation (L+R) signal, the L+R and L-R signals thus derived being placed in phase and combined through sum and difference circuits to obtain the stereo related (L and R) outputs.          Demodulation distortion may be minimized by inverse amplitude modulation of the carrier wave with a portion of at least the envelope fundamental (and preferably also one or more harmonics thereof).  The carrier wave is preferably enhanced prior to quadrature demodulation and preferably is also-modulated with an infrasonic frequency (e.g. 15 Hz) signal indicating stereo signal presence, with such infrasonic modulation either ampli-tude modulating or phase modulating the carrier wave.  Such infrasonic modulation is utilized to automatically switch receiver output mode and to visually indicate stereo signal presence.

A louvre is inserted horizontally between the two vertical stringers and between two adjacent rungs thereof.  The flap lying to one side holds the ladder obliquely such that the rung above the louvre is to one side of a hole therethrough.  The louvre is then lifted and a vertical needle for inserting an elevating member such as a cord or chain enters the hole as the louvre is lifted.  This lifting motion also lifts the ladder which motion causes the flap to pivot and flip to a position on the other side of the hole so that the next successive rung will be on the other side of the hole and the needle.  The assembly continues and results in the rungs of the ladder being disposed alternately on opposite sides of the elevat-ing member.

Abstract: ABSTRACT OF THE DISCLOSURE         An alloy of nickel and aluminum, which also may contain varying percentages of intermetallics, in the form of a wire or rod is sprayed in an electric arc spray gun to form a self-bonding coating on a smooth, clean substrate.  Alternatively an alloy of nickel and titanium, which also may contain varying percentages of intermetallics, in the form of a wire may be similarly electric arc sprayed to effect a self-bonding coating on a substrate.  The nickel aluminum alloy and possible inter-metallics or the nickel titanium alloy and possible inter-metallics are supplied as a wire feed to the electric arc spray gun, and when heated in the electric arc of the spray gun and sprayed onto a substrate will form a coating that has a high degree of tenacity to many metal substrates and also has a moderate degree of hardness, low Rc, high Rb.  The self-bonding is attributed to the formation of superheated liquid in the arc process and the affinity of the superheated liquid to iron, nickel, aluminum, etc.
