Abstract: ABSTRACT OF THE DISCLOSURE      Circuitry for attachment to a radio receiver to monitor and test a detected intermediate frequency signal and an audio signal from a demodulator portion of the receiver to determine whether a transmitted radio frequency signal is within frequency tolerances and modulation limits and to provide an alarm, either visual or audio, when the limits or tolerances are exceeded.  An off frequency monitor tests the DC component of the radio de-modulator detected IF signal and includes input signal conditioning circuitry  for filtering the audio signal,  high impedance for minimal loading of the radio, and level shifting.  Upper and lower level voltage references indicate maximum permissible fre-quency deviation from the nominal transmitting frequency.  Upper and lower level comparators compare the conditioned direct current (DC) signal to the respective voltage references and provide a changed output state upon an out of tolerance transmission.  An over modulation detector, generally in parallel with the off fre-quency monitor, provides a changed output state of a minimum time duration whenever the modulation limits are exceeded, and includes AC coupling to block the DC component of the radio detector signal, a voltage reference indicative of the maximum modulation level, a comparator for comparing the audio signal to the voltage reference, pulse stretching circuitry to provide a minimum time duration output for intermittent over modulation conditions.          The frequency monitor and modulation detector independently control switching of alarm circuitry to enable either a light emitting diode, or a volume controlled audio oscillator.

Abstract: A B S T R A C T      The cost of drilling a water sensitive shale is reduced by first enhancing drilling rate by circulating a clear drilling fluid, then avoiding borehole instability due to shale-water interaction by circulating an aqueous solution of 10-20% hydrolyzed polyacrylamide and alkali metal halide. Borehole instability due to mechanical incompetence of earth formations may be avoided by circulating a suspension of pre-hydrated bentonite in the said solution to enhance the borehole cleaning while continuing the shale stabilization.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention disclosed sets forth a method and machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web.  The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats.  Predecorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature.  Such a label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam the overlap to make a sleeve.  The sleeve is stripped onto the top neck end and over the closure of a bottle of room temperature to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking the material onto a "cold" bottle.

Abstract: ABSTRACT OF THE DISCLOSURE An arrangement for guiding paper during its transport in print-ers includes a rotary platen over which the paper is guided.  In preventing the formation of wavy bulges when the paper is advanced, there is provided in front of the paper and extending across its width a guide element which is adapted to deflect the paper from its direction of advance in such a manner that the paper is pressed against the rotary platen by pressure rollers.  The guide element is movable from a first position in which it does not obstruct movement of the paper towards the platen to a second position in which it deflects the paper.  In this way, the paper contacts the platen at a point in advance of the point at which a pressure roller is arranged.  The guide element is pivotably mounted and biased to the second position by a spring. The arrangement is suitable for the slack-free advancing of paper in tele-printers.

Abstract: APPLICATION FOR UNITED STATES PATENT            A METHOD FOR RECOVERING GAS FROM   SOLUTION IN AQUIFER WATERS ABSTRACT OF THE DISCLOSURE   In a method for producing hydrocarbon gas from aquifers which contain gas in water solution, water is produced from wells distributed through the aquifer and solution gases are recovered from the produced water.          The aquifer pressure declines as production continues; gas comes out of water solution and a gas phase saturation builds up in the aquifer.  When gas saturation exceeds a critical value, gas in gaseous phase flows through the aquifer rock to the producing wells and the ratio of total gas to total water produced increases substantially.

Abstract: IN THE CANADIAN PATENT AND TRADEMARK OFFICE     Title :    Pellet Mill Inventor :     Abstract  of  Disclosure.            A cylindrical die for a pellet mill for animal feed-stuffs is releasably clamped to a rotatable die holder by means of a series of clamping segments disposed in a recess at the end face of the die holder. The recess has a radially outer conically diverging surface which cooperates with conically shaped outer surfaces on the segments to produce clamping of the radially inner faces of the segments on an end portion of the die.          The clamping segments are urged into engagement by springs acting on rods connected to the segments and are dis-engagable by means of a series of hydraulic rams which can be actuated to oppose the force of the springs. The direction  of the forces is chosen to be at an angle to the axis of the die holder so as to cause the clamping segments to follow the surface of the recess and to move radially away from the die during disengagement. The angle chosen is preferably the angle of divergence of the recess. In a modification centering segments are inter-digitated with the clamping segments.

Abstract: ABSTRACT OF THE DISCLOSURE      In an aerial reconnaissance photographic camera, the exposure aperture 15c of a revolvable focal plane shutter blind is varied by varying the relative positions of an outer part 15a and an inner part 15b of the blind.  Two helical driving gears 22 and 23, of opposite hand to each other and fixed on a common shaft 24, respectively drive helical gears 19 and 21 (also of opposite hand to each other) the gear 19 driving outer blind part 15a through one pulley and belt system, the gear 21 driving inner blind part 15b through another pulley and belt system. Axial displacement of shaft 24 produces relative rotation between gears 19 and 21 and hence variation of aperture 15c.  The shaft 24 is rotated (by co-axial shaft 11) at a speed directly proportional to aircraft speed and inversely proportional to aircraft height, with the result that the frequency of the exposures is variable, and the shaft 24 is displaced axially according to its speed (to compensate for the speed of the shutter by varying the aperture) and according to the light conditions.
