Abstract: WELL CASING PERFORATOR                  Abstract of the Disclosure A well casing perforator adapted to be used with pneumat-ically powered rotary drilling equipment.  It includes an upright elongated body which is inserted within the casing.  The body is attached to the lower end of a drill rod which imparts vertical or angular movement to the elongated body while within the casing.          The body is guided axially within the casing by rollers which engage the interior casing wall.  A rotatable wheel has teeth cap-able of penetrating the casing wall is the wheel rolls in engage-ment with the casing.  The wheel is mounted at the outer end of a carrier pivoted to the elongated body about a horizontal axis.          The carrier in turn is controlled by a piston assembly subject to pneumatic pressure within the drill rod.  The piston assembly is pivotally connected to the carrier to move it from a first posi-tion at which the wheel is retracted from engagement with the casing to a second position at which the wheel engages the interior wall of the casing.  Upon subsequent downward movement of the body, the wheel and carrier are moved to a third position at which the wheel teeth penetrate the casing as the wheel rolls with its teeth in engagement through the casing.  Upward movement of the elong-ated body following release of pneumatic pressure in the drill rod permits return of the carrier and wheel to their original retracted position.

Abstract: ABSTRACT OF THE DISCLOSURE   A flexible hose construction and method of making same are pro-vided herein.  The hose construction comprises a flexible nylon-11 base tube, a braided reinforcing layer disposed around the base tube, and a layer of adhesive means between the base tube and reinforcing layer.  The reinforcing layer consists of a mixture of urethane prepolymer and a cross-linking material, the cross-linking material comprising 4,4'-methy-lene-bis-chloroaniline, the layer of adhesive means being a solely ambient air cured adhesive means and comprising the sole means bonding the braided reinforcing layer and the base tube yet providing a tenacious bond therebetween.  The braided reinforcing layer is thus disposed and is tenaciously bonded against the base tube without the necessity of special heat or chemical treatment, thereby avoiding an increase in the overall cost of the hose construction.

Abstract: ABSTRACT OF THE DISCLOSURE     A process and apparatus for neutralizing hot acid gases is disclosed.  Prior to neutralizing the gas, it is intro-duced into a zone, e.g., a cyclone to establish an upwardly, generally spiral gas stream.  This gas motion permits removal from the gas of larger particles which concentrate at the cyclone wall by centrifugal forces.  The upwardly-moving gas stream which may or may not have a spiral motion is contacted with an upwardly-moving spray of a basic neutralizing liquid or slurry under con-ditions such that the spray droplets moderately overcome gravi-tational forces such that they experience a sufficiently long residence time in the cyclone to be evaporated to dryness.  The product gas from the cyclone then can be treated further to re-move small particles and salt product.

Abstract: AC MOTOR DRIVE SYSTEM HAVING CLAMPED COMMAND ERROR SIGNAL                ABSTRACT OF THE DISCLOSURE Disclosed is a three phase AC motor drive system wherein a variable frequency variable magnitude AC current is fed to an AC motor load from a thruster controlled DC to AC inverter which is supplied from a thyristor controlled AC to DC converter by way of a DC link including an inductor.  The DC load current is commanded to rise at a rate limited by the difference between the output voltage of the converter and the input voltage to the inverter which voltage appears across the inductor.  As a result of the inherent commutation transport lag encountered for commands in the negative direction, an error signal clamp is placed in a feedback signal path controlling the AC to DC converter for limiting the command for changes in the positive direction thereby providing a system response in the positive direction which is more nearly like the response in the negative direction.
