Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a fiber optic cable connector assembly and more particularly to fiber optic cable connectors which, when mated, form an assembly which accurately aligns and spaces the terminal ends of one or more fiber optic pairs,  Fiber optic con-nector assemblies must properly align and closely space the terminal ends of the optical fiber pairs to very exact tolerances,  Fiber optic connectors have generally included terminating pins constructed from rigid material which re-ceive the optic fibers and support them in the connector, In many cases, damage to the pins or other connector com-ponents result during servicing,  The connector assembly of the present invention includes a connector having a cable terminating tubular pin which receives one of the cables and which also has an outer circumferential flange.  The pin is received within a channel of the connector body which channel has a forwardly facing annular shoulder portion.       A cylindrical retainer coaxially disposed about the pin has a rear surface engaging the channel shoulder and forwardly depending fingers engaging the pin flange.  The rearward end of the retainer also includes an integral spring mechan-ism which urges the pin in the forward direction so that its forward end continuously engages a spacer within a mating connector which causes the terminal ends of the coupled cables to be closely and controllably spaced for efficient light transfer between the fiber optic cables.  This assembly allows ease of manufacture and facilitates disassembly of the connectors during servicing.

Abstract: ABSTRACT OF THE DISCLOSURE     A well tool is disclosed for shifting the sleeve of a port collar in a well casing, to open and close the ports in the collar.  The tool is made up of a housing having a double piston assembly mounted slide-ably in a transverse bore in the housing.  The trans-verse bore is intersected by a lengthwise bore in the housing.  Fluid is carried into the housing from a tubing string connected to the lengthwise bore.  The double piston assembly has an outer face in contact with fluid in the well casing, and a smaller area inner face in contact with fluid inside the housing bore. This differential in the piston surface area holds the piston assembly in a "retract" position by the fluid pressure on the outer face.  Alternatively, the piston assembly can be moved laterally to engage the port collar sleeve by applying a differentially higher fluid pressure to the inner face.  Pulling the tubing string upwardly shifts the sleeve to a position which opens the collar ports.  Setting weight on the tubing string moves the sleeve downwardly to close the collar ports.     28,230-F

Abstract: _ 21 _ DEVICE FOR PRE-SELECTING THE EFFECTIVE OPERATION OF SOME OF THE CYLINDERS IN A MULTI-CYLINDER ENGINE      ABSTRACT OF THE DISCLOSURE  .       This device is for use on a multi-cylinder engine which includes a carburetor having two or four barrels.          Half of the barrels are operatively connected to half of the cylinders which operate in a normal manner.  The other half of the barrels is operatively connected to the remain-ing cylinders and is provided with means whereby the volu-metric efficiency of this other half of the cylinders may be selectively varied from complete inoperation, in stages up to full operation.   This was accomplished by the in-stallation of an apertured plate between the carburetor and the intake manifolds, there being an aperture for each barrel of the carburetor.  In one half of the apertures, a cylindrical sleeve is located into which may be placed a solid plug for complete inoperation of these cylinders or an apertured plug if partial operation is required.  The size of the aperture in the plug controls the volumetric efficiency of the cylinders operatively connected thereto so that, for example, an eight cylinder engine can operate as though it was provided with four, five; six, seven or eight cylinders by choosing the relative plug to be fitted within the cylindrical sleeve.

Abstract: ELECTRICAL CONTROL FOR POWER SHIFT TRANSMISSION                 ABSTRACT OF THE DISCLOSURE       An electrical control provides output signals to a group of solenoid valves which control the gear ratio selected by a transmission.  The electrical control receives input signals from a mode select lever, an upshift/downshift pulser lever, an engine RPM sensor, a ground speed sensor, a clutch position sensor switch, and a throttle control lever.  The mode select lever has a neutral (N) position, a reverse (R) position, a forward manual (FM) position, and a forward automatic (FA) position.          Movement of the mode select lever from N to FM causes the electronic control to actuate solenoid valves which select a first forward gear.  Similarly, movement of the lever from N to R causes the control to actuate solenoid valves which provide a first reverse gear.  Higher/lower gears are obtained by moving the upshift/downshift pulser lever from its normal position to either an upshift position or a downshift position.  One upshift pulse causes the electronic control to actuate solenoid valves resulting in one gear shift upward.  Holding the pulser lever forward in the upshift position gives sequential upshifts at predetermined time intervals.  Pulsing or holding the pulser lever rearward in the downshift position has a reverse effect.  When the forward automatic mode is desired, the operator first moves the mode select lever to FM and operates the pulser lever until the desired maximum gear has been attained.  The operator then moves the mode select lever from the FM to the FA position.  Thereafter the control upshifts and downshifts the transmission according to engine RPM and the desired throttle set point.

Abstract: ELECTRICAL PROTECTIVE DEVICES                 AND METHODS OF ASSEMBLING            Abstract A protector module for protecting tip and ring conductors of a telephone loop includes a pair of protector assemblies which are supported within a common housing.  A voltage protection subassembly of each protector assembly is connected electrically to a grounding subassembly for causing current associated with excessive voltage surges to be conducted to ground.  Each protector assembly also includes a current protection subassembly which comprises a dielectric base and a line pin and a central office pin with the line and central office pins being connected together electrically to establish electrical contact between a conductor of the circuit and its protector assembly.  A shunting element is disposed concentrically about the line pin and is releasably secured to one end of the line pin in an initial position by a fusible bonding material.  A spring between a cup of the voltage protection subassembly and the housing maintains the voltage protection subassembly in engagement with the shunting element.  Also, the spring is effective when current flow exceeds a predetermined level that is sufficient to melt the fusible bonding material to cause the shunting element to be moved to a position where it engages a portion of the grounding subassembly to establish a fault current path to ground.  For a prolonged voltage surge, heat energy is transferred from the voltage protections subassembly to the shunting element and melts the fusible bonding material to allow the shunting element to be moved as in a current overload mode.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed are refractory plate valves for controlling flow of molten material with structure providing a uniform controllable variable sealing pressure over the entire area of the sliding plate surface which surrounds the depending nozzle sufficient to deflect the refractory plates into a sealing relationship to prevent the intrusion of the molten material between the plates.  One embodiment provides for peripheral support to prevent breakout even if thermal and abrasive wear of the plates allows formation of a fin of solidified material between the plates.  The uniform pressure is applied to the sliding plate by pressurizing a fluid within a chamber in the sliding gate carrier that is immediately below a flexible diaphragm supporting the sliding plate.  This pressure is applied from an external or internal source and may be controlled during the tapping and teeming phases of the use cycle and additionally may he completely relieved for ease of opening and closing of the device during the service phase of the cycle.  The valves can be sliding valves of either the reciprocating or rotary style valves and can be either two plate or three plate variety.  The valves can be sequential style in which individual plates are sequentially pushed or pulled under the opening to control flow.  Likewise, there are various devices for opening and closing of the valve for servicing, or for reciprocating or rotating the sliding plate.  The uniform pressure principle is applicable to refractories which are metal encased, bonded in, or banded, and to refractories which are symmetrical or assymmetrical. The stationary and sliding plates may optionally be identical or of different shape and/or thickness.

Abstract: ABSTRACT OF THE INVENTION      An adaptive control for a turning machine which adjusts the machining rate to maintain the actual horespower dissipated at the cutter tip at a constant set point despite changing workpiece and cutter parameters.  The machining rate is adjusted by control of the machine drive and tool feed to achieve required SFM and IPR values, respectively, within maximum and minimum SFM and IPR limits.  "Speed" and "Axis" override controls are also provided.  The rate of adjustment of SFM and IPR to a deviation of the cutter tip horsepower from the set point is inversely proportional to the measured system gain so that the response factor of the control loop is maximized.  The commanded machining rate or (SFM) (IPR) product is periodically determined by estimating the actual machining rate and multiplying the estimate by the ratio of the set point to the cutter tip horsepower. The cutter tip horsepower is determined by subtracting the electrical loss, mechanical friction loss, and the net power required for net acceleration for the drive, from the measured electrical power supplied to the drive motor.  The cutting efficiency is monitored to perform tool wear, tool breakage, and tool protection functions.  The adaptive control also has soft engagement and soft disengagement functions for initiating and terminating the adaptive machining process.
