Abstract: Abstract of the Disclosure The following specification describes a circuit breaker enclosure having a cover, which is latched closed by spring biased latch handles.  The handles and cover move in response to gas pressure for relieving the pressure generated on tripping of the circuit breaker.  The latch handles are arranged to point outwardly of the enclosure, when open, to provide a clear visual indication of their being open.  The circuit breaker handle and enclosure handle are directly engaged with a common pivot pin for synchronous movement to enable the enclosure handle to indicate the trip condi-tion of the breaker.  When the cover is open, the handles are interlocked against movement to an ON position by a biased pivot-able interlock plate.  The cover in turn is latched closed through the interlock plate and a breaker handle plate, when the circuit breaker enclosure handles are in the ON position.  A pair of spaced edge projections on the enclosure wall engage the cover sealing gasket to avoid a permanent compression set in the gasket.

Abstract: 1. BE IT KNOWN THAT RICHARD D. RIDLEY of 2224 First Street, Grand Junction, Colorado 81501 United States of America and GORDON B. FRENCH of 7684 North Quartz Street, Golden, Colorado 80401, United State of America having made an invention entitled: "In situ recovery of shale oil" the following disclosure contains a correct and full des-cription of the invention and of the best mode known to the inventors of taking advantage of the same. ABSTRACT An in situ ore, e.g. oil shale, retort containing a frag-mented permeable mass of particles is formed in a subterr-anean formation containing, e.g., oil shale by excavation an open base of operation in the formation at an elevation above the fragmented mass to be formed, excavating an access drift to provide access to the bottom of the retort site and explos-ively expanding formation to form the fragmented mass bet-ween the access drift and an elevation spaced below the bott-om of  the base of operation, leaving a horizontal sill pillar of unfragmented formation between the top of the fragmented mass and the bottom of the base of operation. The sill pill-ar provides a safe base of operation above the fragmented mass after it is formed. Products, e.g. shale oil, are rec-overed from the retort by introducing gas into the fragmen-ted mass from the base of operation via holes extending throu-gh the horizontal pillar, e.g. blasting holes utilized during explosive expansion of formation, for establishing a combust-ion zone in the fragmented mass and for advancing the com-bustion zone through the fragmented mass. The holes have sep-arte valves located in the base of operation for use in con-trolling gas flow thorough selected regions of the fragmented mass.

Abstract: Abstract A transmit-receive type buried metal detector is described employing wide gating pulses to transmit a portion of the received signal through a gate means to an averaging means for reducing any noise in the signal.  The gating pulses are centered on the received signal waveform at a centering position where a background signal component of such received signal is of minimum amplitude.  As a result, equal positive and negative polarity portions of the background signal component are transmitted through the gate means during each pulse and are averaged to zero in order to eliminate such background signal from the output voltage of the averaging means.  The background signal component may be produced by mineralized soil or by undesired metal objects located near the metal object sought to be detected.  As a result, the mineral soil signal component or the background signal component of the undesired metal objects is eliminated from the output voltage of the averaging capacitor.  This enables detection of the desired metal object in mineral soil or enables such desired metal object to be discriminated from undesired objects.  A wide gating pulse greater than about 1/3 cycle and preferably equal to approximately 1/2 cycle of the oscillator signal, is used for improved noise rejection including random noise of high frequency and harmonics of 60 hertz power line frequency which are close to harmonics of the oscillator signal.  In addition, first and second opera-tional amplifiers are provided on opposite sides of the gate means and a shunt resistor is connected between the inputs of such amplifiers to provide a second path for the received signal in parallel  with the first path through the gate means.  The second path provides an overall gain of -1 to the output of the gating circuit when the gate means is nonconducting for 1/2 cycle, and combines with the first path to provide and overall gain of +1 when the gate means is rendered conductive for the other 1/2 cycle.  This results in balanced demodulation by which both half cycles of the received signal are averaged to produce the output voltage, thereby increasing the sensitivity and signal-to-noise ratio of the metal detector circuit.

Abstract: ABSTRACT OF THE DISCLOSURE As documents are moved serially past a servo motor-driven endor-ser, it endorses a stamp upon each.  A transport signal dependent on docu-ment speed, and an endorser signal generated by an optical tachometer mounted to the servo motor, provide input to a frequency comparator.  The output of the comparator is a control signal which controls the servo motor speed to adjust the endorser rotational surface velocity to equalization with the document speed.  Logic circuitry sets the endorser at a zero angular position.  Responsive to an endorse command, the endorser is acceler-ated to document speed, receives ink from a supply roller, then endorses the passing document.  A counter and a digital comparator in cooperation with the tachometer signal completion of the endorsement whereupon the endorser is decelerated and placed in the zero position.  Should a succeed-ing endorse command occur prior to complete deceleration, acceleration is resumed after a delay count given by a PROM and based upon the pulse count when the succeeding endorse command is received.
