a. 1. Of or pertaining to kissing; kissing. “The osculatory ceremony.” Thackeray. [ 1913 Webster ]

2. (Geom.) Pertaining to, or having the properties of, an osculatrix; capable of osculation; as, a circle may be osculatory with a curve, at a given point. [ 1913 Webster ]

Osculatory circle. (Geom.) See Osculating circle of a curve, under Circle. --
Osculatory plane (to a curve of double curvature), a plane which passes through three successive points of the curve. --
Osculatory sphere (to a line of double curvature), a sphere passing through four consecutive points of the curve. [ 1913 Webster ]

n. [ LL. osculatorium. See Osculate. ] (R. C. Ch.) Same as Pax, 2. [ 1913 Webster ]

n. 1. One that oscillates; specif.: (Electronics) Any device or circuit for producing electric oscillations, whether of current or voltage; esp., an apparatus for generating electric waves in a system of wireless telegraphy. Oscillators are essential components of radio transmission devices and digital computers, as well as many other types of electronic device. In computers the oscillator provides the voltage impulses which permit information bits to be transferred between parts of the computer in a defined sequence. [ Webster 1913 Suppl. +PJC ]

2. (Mech.) An instrument for measuring rigidity by the torsional oscillations of a weighted wire. [ Webster 1913 Suppl. ]

‖n. pl. [ NL. See Oscillatory. ] (Bot.) Same as Oscillaria. [ 1913 Webster ]

a. [ Cf. F. oscillatoire. See Oscillate. ] Moving, or characterized by motion, backward and forward like a pendulum; swinging; oscillating; vibratory; as, oscillatory motion. [ 1913 Webster ]
