Abstract: ABSTRACT      An injection laser diode transmitter contains a detector arrangement that permits the quality of the signal transmitted over a fiber optic link of interest to be monitored for degradation and error detection, by examining the transmitted optical pulses.  The transmitted signal component is extracted from the back facet of the ILD for feedback stability control purposes and is coupled to signal quality measuring circuitry from a wideband current-to-voltage converter that is coupled to the output of a fast photo diode that extracts the optical output signal from the rear facet of the ILD for the purposes of generating a feedback control voltage to be used for ILD bias control.  The bias current generated through a feedback loop from the fast photo diode to the wideband current-to-voltage converter feeds reference amplifier, the output of which is coupled to a lowpass filter to remove the pulse signal component.  The output of the low pass filter is a DC voltage level which is directly proportional to the average optical output of the ILD. The voltage level output of the lowpass filter is applied to a current sink coupled to the ILD. The bias current for the ILD is controlled to drive the differential to zero.  Because the bias current control feedback loop is responsive to the optical output of the ILD, the bias current is automatically compensated for changes in temperature.     The current-voltage converter output is further coupled to a buffer amplifier to supply an output voltage to downlink signal quality monitoring circuitry. In a repeatered, multichannel fiber optic communication system, this quality-indication signal availability facilitates a fault isolation scheme wherein the transmitter outputs are examined selectively.

Abstract: ABSTRACT An extruded strip of resilient gasket material forms an annular gasket of the type designed for enclosure in a coupling housing in coupling of groove end pipe.  The strip has a cross section which comprises: two base portions, two side portions, two compression pads, two resilient arms connected one to each of the respective base portions and extending there-between, a tongue portion and two lip portions.  The side portions extend downward from the base portions and the compressive pads extend upward from the base portions.  The tongue portion extends between the base portions below the resilient arms and has a curved shape such that its middle portion is lower than its end portions.  Each lip portion extends inward from a respective one of said side portions.  The top face of the tongue portion and the bottom faces of the resilient arms define a compensation well.  The bottom face of the tongue portion, the top face of each lip portion and the inside face of the respective side portion respectively defining two cavities. The lip's bottom faces have a smooth texture for efficient sealing against a pipe's external surface.  The tongue's bottom face has a smooth texture for efficient sealing against a pipe's external surface, and the tongue portion has a substantial degree of flexibility.

Abstract: LOW VOLTAGE CARTRIDGE FUSE DESIGN     Abstract of Disclosure This invention relates to electric fuses meeting the requirements of Underwriter's RKl classification.  It includes a high-current interrupter in the form of a fusible element having serially arranged points of reduced cross-section and a low-current interrupter in the form of a plunger soldered to the high-current interrupter.  The plunger is spring biased, and when the solder joint softens, the plunger separates under the action of the spring from the fusible element leaving a large gap between them.  The separation of the plunger from the fusible element is allowed to be particularly large on account of the fact that the plunger may be allowed to move into a special fuse cap, known as a cap having a rejection feature as described, for instance, in U.S. Patent 2, 943, 295 to V.

Following distillation of the reaction mixture to recover a recycle stream of hydrogen fluoride, the isobutyroyl fluoride residue is partially hydrolyzed in the presence of a hydrogen fluoride acceptor resulting in a hydrolysis pro duct consisting essentially of isobutyroyl fluoride, iso-butyric acid anhydride and a hydrogen fluoride complex of said acceptor.  Following removal of the solid complex, the hydrolysis product is fractionally distilled to yield an overhead fraction of isobutyroyl fluoride for reuse in the hydrolysis reaction.

Similarly, a controlled amount of fuel is introduced to the metering chamber, the amount of fuel determing the amount of fuel injected into the associated cylinder of the engine per engine cycle.   The fuel being  fed  to the timing and metering chambers are controlled by individual control units, which may take the form of a variable orifice, the variable orifice being responsive to control  signals generated by an electronic control unit.  The output of the  electronic  control  unit  is  responsive  to  engine operating  conditions  which  are  sensed  by  appropriate sensors.

Abstract: Abstract of the Disclosure A metering valve which is particularly advan-tageous for use in gas mixing devices such as patient ventilators, to accurately control the volume and fre-quency of gas flow for each gas and to provide a feed-back of the actual flow through the valve.  A valve as-sembly which is infinitely openable within its operating range is connected to the core of a linear variable differential transformer.  As the valve opens, the core of the transformer moves, causing a change in the output voltage from the transformer.  The change in output voltage from the transformer can be interpreted by a microprocessor to discern the actual flow through the valve.  Two or more of the metering valves can be used to accurately control the mixture ratios of two or more gases.
