Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is provided for removing a flexible tubular conduit from around an elongated rigid supporting mandrel which is at least several feet long, with said conduit having at least one integral helical reinforc-ing wire extending along the length thereof.  The apparatus includes a sup-port structure for the  mandrel and its conduit, means for holding an end portion of the conduit in a stationary position, and means for simultane-ously rotating and moving the mandrel relative to the holding means during holding of the conduit by the holding means to remove the mandrel from within the conduit.  Such means for rotating and moving operates to rotate the mandrel. in a direction opposite the direction of rotation of the helical reinforcing wire.  This causes radial expansion of the conduit relative to the mandrel.  As a consequence, this enables easier moving of the mandrel relative to the holding means.

Abstract: ABSTRACT OF THE DISCLOSURE A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly.  The system employs a motion conversion unit at either or both control and controlled station, said units serving to convert rotary motion into linear motion, and vice versa.  That is, a force transfer shaft is rotatably mounted in the housing of the motion conversion unit to receive, or impart, rotary motion, and the core element of the push-pull control cable assembly -- which receives, or imparts, linear motion -- extends into, or through, the unit in transversly spaced relation with respect to the shaft.  That portion of the normally flexible core element which extends into, or through, the unit is made rigid to impart columnar strength. A crosshead is secured to the rigidified portion of the core element and is slidably received within a first guideway presented from the housing to minimize lateral loading to the rigidified portion of the core element.  The crosshead is also slidably received in a second guideway provided on a throw arm secured to the shaft.  Movement of the crosshead simultaneously along the two guideways permits a conversion to be effected between the linear movement of the core element and the rotary movement of the force transfer shaft.  A universal mounting plate is also disclosed which permits the unit to be mounted in a plurality of dispositions in order to suit the orienta-tion required for various environments.

Abstract: ABSTRACT OF THE DISCLOSURE        An enzyme referred to as carbon monoxidase and referred to here inafter as CMase is present in animal tissue such as the plasma or cells of red blood and in various bacterial and plants, including algae and fungi.  The enzyme is effective for the conversion of carbon monoxide in a gas stream.  Where the conversion is the step of oxidizing CO to CO2, the enzyme can be used for detection of CO.  The procedure lends itself to quantitative determination of CO in a gas stream.  The production of CMase can be accelerated by growing bacterial cultures or plants in an atmosphere containing an increased concentration simultaneously is also beneficial to the process.           A filter medium including CMase can substantially decrease the concentration of carbon monoxide in a gas stream, the gas stream of particular interest being tobacco smoke.  Combining the CMase in a filter with compounds which bind CO reversibly presents advantages.

Abstract: ABSTRACT OF THE DISCLOSURE         Impact energy absorbing pipe restraints are provided which include a laminated strap for surrounding at least a portion of the circumference of a high energy pipe to restrain the movement of the high energy pipe in at least one direction during rupture.  The laminated strap is formed of a ductile material, i.e., one having the property of substantial elonga-tion in the plastic state, to absorb the impact energy of the ruptured pipe.  Advantageously, an elastic anchor means is affixed to the ends of the laminated strap to anchor the laminated strap about the high energy pipe and enable pivotal movement of the laminated strap relative to the high energy pipe to minimize any bending moment at the ends of the laminated strap, thereby minimizing any detraction in the allowable strain of the laminated strap.  Another form of impact energy absorbing restraint device includes a pipe positioned adjacent the high energy pipe and arranged substantially transverse to the longitudinal axis thereof to restrain the movement of the high energy pipe in at least one direction by absorbing the impact energy of the high energy pipe during rupture by crushing of the restraining pipe therewith.  Advantageously, crushing of the restraining pipe causes the ends of the restraining pipe to move upward so that in effect a well is formed by the restraining pipe which aids in the absorption of energy and restricts lateral movement of the ruptured high energy pipe.
