Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed are a process and apparatus for producing an identification element having an integral holographic recording as part thereof.  The identification element is formed using an interference pattern produced by combining an object beam and a reference laser beam.  The object beam is produced by reflection of information on the identification element.  The interference pattern is recorded on light sensitive material which is firmly and durably combined with the identification element.  Unlike prior arrangements, the hologram (interference pattern) is not produced separately and then united with the card, which could result in errors or damage to the hologram.

Abstract: SUPERVISORY CIRCUIT FOR MONITORING            SPEAKER COILS              ABSTRACT OF THE DISCLOSURE         In a system with a plurality of loud speaker enclosures, a supervisory system is provided to monitor the speaker coils.  Each enclosure has a relay, and -the relay winding is series-coupled with the speaker coil, to maintain the relay contact set closed when there is continuity in the speaker coil.  A fuse, also series-coupled with the relay winding and speaker coil, is sized to blow when the speaker coil shorts and reduces the series circuit impedance.  Accordingly either the speaker coil open condition or the speaker coil shorted condition effects de-energization of the relay winding and releases the nor-mally-closed contact set to signal the speaker coil trouble condition.

Abstract: EXPANSIBLE DRIVE SHAFT TOOK MECHANISM            Abstract An expansible drive shaft tool mechanism is disclosed in which mutually cooperating parallel drive shafts carry tool elements that can be shifted into and locked by shaft expansion in any of selected positions along such drive shafts.  Applied hydraulic pressure in a sealed     chamber causes outward expansion of a flexible outer sleeve member on each such shaft to grip the tool elements.  An inner sleeve member closely encircled by the outer sleeve member and joined in sealed relationship therewith at opposite end portions forms the radially thin elongated annular sealed    chamber into which the pressurized hydraulic fluid is forced by the action of a plunger type hydraulic pressure source housed inside the inner sleeve member cavity.          Actuation of the hydraulic pressure source plunger passing through a cylindrical fluid take-up chamber by longitudinal displacement is effected by means of a pneumatic piston energizable through a connecting line including a low pressure rotary seal or union.  Hydraulic fluid that may leak past a primary seal along the plunger         is taken up in the seal chamber which, of cylindrical form, incorporates a sliding piston or seal element contacting the plunger  and cavity wall and urged by a return spring to exert pressure on such accumulating hydraulic fluid tending to return it to the hydraulic cylinder.  Such seal chamber including the spring-returned seal element is thus avail-able to take up leakage of hydraulic fluid seeping past the primary seal, whether caused by operating pressure or by thermal expansion of fluid in the system, and to urge the fluid back through a check valve when the pressure drops again.

Abstract: ABSTRACT OF THE DISCLOSURE         A vacuum-type circuit breaker comprises a conventional wipe mechanism interposed between an operating member and the movable contact of the breaker.          The wipe mechanism comprises a driven part coupled to the movable contact, a driving part coupled to the operating member but movable with respect thereto, and preloaded spring means between said driving and driven parts.         First stop  means is provided for stoppping said operating member at the end of its circuit-breaker opening stroke with such abruptness that said driven member, against the opposition of said spring means, overruns the driving member following such stopping.       Such overrunning of the driven member is limited by second stop means comprising a stop carried by said operating member.  This stop engages the driven member and thus blocks said overrunning after a limited amount of such overrunning sufficiently low to prevent damage to the usual bellows of the vacuum circuit breaker despite thousands of excursions of the driven member through said overrunning travel.

Abstract: "TRANSITION METAL CATALYST"                 ABSTRACT OF THE DISCLOSURE              A transition metal catalyst suitable for use in the synthesis of ammonia is produced by doping a carbonaceous support material with a solution of an alkaline earth metal compound, a solution of a compound of a transition metal from Group VIII and a solution of an alkali metal compound.  Each doping is performed separately; the product of each step is baked to obtain a catalyst having a black and lustrous sur-face.  The doping and the baking operations are preferably conducted under vacuum, The catalyst is preferably prepared with barium as the alkaline earth metal, ruthenium as the transition metal and potassium as the alkali metal,  The carbonaceous support material can additionally be doped with a solution of a compound of a lanthanide metal and/or a solution of a compound of a Group IIIA metal.              The present family of catalysts provides good ammonia yields in the fixation of nitrogen at temperatures as low as 375°C and at pressures ranging from 27 - 67 atmospheres,  The activity of these catalysts drops in the presence of carbon monoxide but returns to substantially the initial activity when the carbon monoxide is removed from the reactant stream.

Abstract: ABSTRACT An animal trap having a self-latching trigger is dis-closed.  The trap includes at least one jaw pivotally mounted to a base and spring biased from a set position to a release position.  The trigger includes a trigger arm resiliently biased toward the set position.  A sear is pivotally mounted to the base and freely rotatable between set and release positions. The sear has one contact surface which engages the trigger arm in the set position.  A second contact surface on the sear is disposed within the rotational path of the jaw and in the set position engages the jaw to retain it against the spring bias-ing force.  To set the trap the jaw is rotated from the release to the set position.  During such rotation the jaw engages the second contact surface pivoting the sear to the set position while the trigger arm is biased toward the set position.  The trigger arm automatically snaps into contact with the first contact surface of the sear.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved heat exchange tubing and blade assembly and a method for fabricating the same is described.  The heat exchange assembly comprises on elongated tube and on elongated heat exchange blade strip positioned thereon.  The heat exchange strip includes an array of integrally formed blade segments which extend from a U-shaped support segment of the strip.  Surfaces of the blades extend at a favorable angle of attack to the incident fluid flow stream, and in a preferred embodiment the chords of the blades extend in a direction substantially normal to a longitude-nal axis of the tube.  The strip is supported on an outer surface of the tube, and a means integrally formed with the tube maintain the support segment in thermal contact with the tube.  In a presently prefered embodiment, the tube has a generally streamlined oval cross section for utilization in heat exchanger apparatus such as in an air conditioner, refrigerator or heat pump, with the tubing arranged such that the minor axis of the oval extends per-pendicular to the external fluid flow and its major axis extends parallel therewith for reducing the frictional drag and reducing stagnant regions of the external fluid flow.  The multiple blades fan out from opposite sides of the oval tubing along its two gently curving arcuate faces where the fluid flow is relatively fan out from opposite sides of the oval tubing along its two gently curving arcuate faces where the fluid flow is relatively unimpeded.  Moreover, the individual blades in a preferred embodi-ment are tapered so as to decrease in thickness from root to tip, thereby reducing the mass and weight of thermally conductive material in the blade strips while providing suitable thermal con-duction and mechanical strength in the individual blades.
