A multi-fiber fiber-optic connector is provided containing a cartridge having a front radial flange containing peripheral, circumferentially-spaced notches in each of which a fiber-optic terminal is axially positioned, and having a rear radial flange containing peripheral, circumferentially-spaced notches in each of which a fiber-optic clamp body is axially positioned. The fiber-optic terminals are spring-biased forwardly toward the open end of the connector, and a preload plate holds them in a preloaded state. Each of the terminals is provided at its outer end with a surrounding, axially-extending resilient split sleeve, the outer end of which is empty to receive a fiber-optic terminal of a mating conductor similar to the above-described connector, but without the split sleeves. Each fiber extends between the front flange and the rear flange non-axially, the crimp-held end of each fiber instead being aligned with the fiber-optic terminal circumferentially next to the one which is aligned with the crimp body for that fiber.

A connector for joining light transmitting fiber cables through a cover (14) to a transmitter and/or receiver device (3) comprises a plug connector half (6) comprising a plug (8) and a transceiver adapter (10), and a clip connector half (5) attached to and integral with the transmitter/receiver device (3) and having apertures (19) therein beveled (20) to receive latching beams (13) of the transceiver adapter (10). The clip connector half (5) further comprises a clip retention slot (21) coextensive to each aperture (19) through a cut-out (22) common to both the retention slot (21) and the aperture (19). The clip connector half (5) further comprises clips (23) each with a dimple (24) adapted to clip within a respective retention slot (21) with the dimple (24) biased through the cut-out (22) in the slot (21) and into engagement with a respective latching beam (13) upon mating of the plug connector half (6) to the clip connector half (5). The clip connector half (5) further has a window (26) on the same side of the clip connector half body (18) as the slot (21) and which is a continuation of the slot (21). The clip (23) comprises a flat, linear body with dimple (24) and wing (25) both emanating from the same plane of the body.

Two optical fiber cables are joined by a connector operative as a switch. The switch includes a snap-action shutter which delivers precise movement with piece parts which can be molded or electromachined. The snap-action is provided by any one of a number of inexpensive implementations which need not be precise because of the constraints on shutter movement imposed by the piece parts.

An apparatus and method for controlling the sequential operation of supplemental electric heaters so that the amount of energy consumption is minimized. The operation of the heaters is prevented as long as a lower night set-back temperature can reach the higher reference set point during the daytime within a predetermined time interval. A microprocessor is provided to control the operation of night set-back automatically to affect a measured temperature of the conditioned space.

An apparatus and method for controlling continuously and discretely the speed of an indoor evaporator fan motor and the speed of the compressor as a function of the fan speed for regulating the dry bulb temperature and relative humidity of a conditioned space includes a programmed control device which produces a first signal for driving a fan inverter connected to the evaporator fan motor. A second signal, which is a function of the first signal, is also provided by the control device to drive a compressor inverter coupled to the compressor. A microprocessor having a program is operatively connected to the programmed control device for controlling its operation to effect the measured temperature of the conditioned space.

A connector (10) between an optical connector (35) and a receptor (11). The connector (10) has a housing (14) with an upper portion (20) and a lower portion (21). A printed circuit board (45) is received in the upper portion (21) and extends outwardly from the front of the upper portion (20). The printed circuit board (45) is vertically and laterally moveable within the upper portion (20). An optical connector (25) is received in, and retained between, side clips (30, 31) on the lower portion (21) of the housing (14). The optical connector (35) is matable with the optical portion (12) of the receptor (11) and the printed circuit board (45) is self-aligning and matable with the electrical portion (13) of the receptor (11).

A polishing bushing for polishing the end face of an optical fiber supported within a rigid sleeve includes a bushing base (31, 131) having a front surface (36, 136). The rigid sleeve (21, 21a) normally protrudes from beyond the front surface (36, 136) to permit the end face (14, 14a) of the optical fiber (12, 12a) carried therein to be polished. The bushing includes resilient portion (34) for permitting the rigid sleeve (21, 21a) to move longitudinally in passageway (38) to limit the force applied to the end face (14, 14a) of the fiber (12, 12a) by the polishing medium. The front surface (36, 136) of the bushing base (31, 131) is of spherical shape to produce a polished fiber end face (14) which is convex and which protrudes from the rigid sleeve (21) by less than about one micron, or is of flat shape to consistently produce a polished end face (14a) which is recessed within the sleeve ( 21a) by less than about one micron.
