Title: Method and apparatus for joining the ends of two  fiber optic cables
Inventor: STILES KENNETH M
IPC: G02B6/38
Filed: 1980-01-09
Granted: 1982-06-29
Abstract: Abstract of the Disclosure A connector for interconnecting the ends of two optical fiber cables to provide accurate alignment of the optical fibers free of stress from the mechanical linkage of the respective cables. The sheath at the adjoining end of each cable is split in two and separated to expose the optical fiber.  The split ends of the sheath are inserted in separate diverging holes in a mounting ferrule while the exposed optical fiber is inserted in a central bore between the diverging holes.  The sheath ends are anchored by cementing the ends in the holes.  Only the very outer end of the exposed optical fiber is anchored by cement in the ferrule to fix the alignment of the fiber.  The rest of the exposed fiber between the anchored outer end and the point at which the sheath is split is bowed slightly to relieve any tension on the fiber.  The ends of the cables are joined by mounting the ferrules in a common connector body with the outer ends of the fibers held in abutting axial alignment.

Abstract: ABSTRACT OF THE DISCLOSURE             A noise removing apparatus is interposed between an FM detecting circuit and a stereo demodulating circuit.  The noise removing apparatus is responsive to a pulsive noise included in the output from the detecting circuit to enable a first gate to interrupt transmission of the output.  Although the stereo pilot signal is disturbed during the interruption period, the disturbed stereo pilot signal is cancelled by a pseudo-stereo pilot signal (a signal similar to the pilot signal) separately generated, whereby the disturbed stereo pilot signal is prevented from being applied to the stereo demodulating circuit.

SLATER, JR.   NEW YORK, NEW YORK  10005 (212)  425-3158 ABSTRACT    A method for the in situ separation of viscous crude oil from a reservoir such as oil shale, oil sand, or tar sand is disclosed.          Hot water is introduced to the top surface of the reservoir while steam is injected into the reservoir through drill holes.  The hot water and steam may contain a surfactant.  The bouyancy of the crude oil creates an artificial water drive which causes the water and oil to "flip-flop' so that the oil rises to the top of the reservoir and separates from the remainder of the reservoir mat-erial.  If the overburden is deep, underground mining techniques may be used to reach the reservoir prior to applying the present method.

Abstract: PHT. 80-443                    -6-ABSTRACT:    An adaptive delta modulator must produce at its output a periodic 0-1 sequence when the input signal (w) to be coded assumes zero value.  However, on account of the unavoidable tolerances of the components used, deviations of a periodic 0-1 sequence are produced.  One of the con-sequences of this fact in an increase in the idle channel noise in the decoded signal at the receiving end.   To obviate this disadvantage, the delta modula-tor is provided with a generator (GE) to produce a periodic 0-1 sequence which is transmitted to the receiver instead of the delta coded signal.  This generator (GE) is switched to the output line of the delta modulator at the instant at which the output voltage (Us) of a filter (IN) for determining the instantaneous quantising unit of the delta modulator, assumes zero value.  If this filter (IN) is implemented with digital components, the generator (GE) is triggered by the output pulses of a gate (G1) whose inputs are connected to the respective locations of the input signal storing means (E) of the filter (IN).  A delay line (V) prevents triggering of the generator (GE) at extremely short pauses in the input signal (w) to be coded.
