Abstract: ABSTRACT OF THE DISCLOSURE         Catalysts comprising the combined oxides of vanadium and at least one element selected from the group consisting of boron, niobium, tantalum, antimony, tungsten and chromium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene, or a mixture thereof with molecular oxygen in the vapor phase to yield maleic anhydride.  The catalysts of the present invention may be further promoted with additional elements to enhance activity, stability and selectivity.  The reaction with n-butane gives an especially pure product in good yield and selectivity.

Abstract: HYDRAULICALLY OPERATED STEER AXLE LINKAGE                  ABSTRACT OF THE DISCLOSURE         An improved Ackerman steering linkage for a steer axle maximizing steering forces available from a given hydrau-lic system pressure and minimizing space requirements.   The lengths of the steer arms and quadrant are minimized by interconnecting a hydraulic steering jack to the quadrant on the diametrically opposite side of its pivot to the axle from its points of connection with the tie rods.  Both ends of the steering jack impart steering forces to the steering linkage thereby reducing the design specification for the effective pressure area of the jack.  The steering geometry improves the steering torque available at extreme steer positions, thus permitting a smaller diameter steering jack to be used.  The improved steering linkage employs components which are sufficiently small to fit within the rims of wheels rotatably mounted on the wheel spindles on opposite lateral ends of the axle.

Abstract: PNEUMATIC REGISTRATION AND CLAMPING APPARATUS     Abstract the Disclosure In a first embodiment, a stop having a plurality of ports is connected to and covers an end of a rectangular sleeve having a movable wide wall.  In a region near the stop, a narrow wall of the sleeve also has a plurality of ports.  A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports.  With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop.  After the sheet has been registered, the movable wide wall is moved towards the other wide wall of the sleeve.  If a sheet is wrinkled, such movement flattens the sheet.  In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered.  In a third embodiment, similar to the first, a manifold is coupled to the ports and a vacuum pump is coupled to the manifold to accelerate registration.  In a fourth embodiment, similar to the third, the pumps are replaced with a reversible pump to register and discharge a sheet.

Abstract: RECORD STORAGE APPARATUS EMPLOYING           ENHANCED TRANSDUCER POSITIONING SERVOMECHANISMS             A sequentially operated machine employs two positionable members, a movable center selection piston member and a movable transducer member for accessing a record storage member selected by the central piston member.  Making the record storage member available to the transducer requires a predetermined time delay. Accordingly, the servomechanism powering the selecting mechanism has a high response, while a following servome-chanism transporting the transducer has a low response such that cost is reduced while not adversely affecting access time to the record member.

Abstract: ABSTRACT OF THE DISCLOSURE      A program controlled workpiece manipulator has a load cell supported between the manipulator clamp and the positioning elements which generate signals proportional to the various components of the forces exerted on the workholder by external instrumentalities.  To generate a desired control program for the manipulator the outputs of the load cell and of the position transducers for the manipulator drive servos are used to generate command signals for the drive servos which urge motion of the clamp to reduce the externally imposed forces.  The clamp is then manually grasped and urged toward the desired motion and the outputs of the position sensors are recorded during the motion manipulator to duplicate the motion.

Abstract: WRIST BAND               ABSTRACT OF THE DISCLOSURE     An identity band which comprises an elongated strap and a latch which forms a slot through which the strap is pushed to form the band into a loop.  The strap has a series of stop surfaces alternating with a series of camming surfaces and within the slot there is a latching element.          As the strap is pushed through the slot to form the loop, the camming surfaces in turn cam the latching element to one side.  The stop surfaces are arranged so that, if an attempt is made to pull the strap in the opposite direction through the slot, one of them engages with the latching element to prevent such movement of the strap.  In one form the camming and stop surfaces are the surfaces of ratchet-like teeth and in another form the surfaces are the transverse edges of apertures formed in the strap.  The latch element is wedge-like and mounted at its thicker end.  The band is formed so that it can be written on or can have a label adhered thereto. The written on portion or label can be covered by a transparent plastics sleeve. Alternatively, the sleeve may hold a loose label in place.  These arrangements permit material identifying the patient to be carried by the band.

Abstract: ABSTRACT OF THE DISCLOSURE         A process incorporating integrated units and combined cycle energy production is provided for the recovery and upgrading of oil containing deposits which are not readily amenable to recovery and upgrading, to produce therefrom a light oil and elemental sulphur. Residual hydrocarbons generated in the process are gasified to produce hot gases which are  used as a source of energy for process use, including electric power. The electric power is utilized to electrolyze water and produce hydrogen for use in upgrading and oxygen for use in gasification.  The integration of gasification of residual hydrocarbons to produce, inter alia, electic power with the electrolysis of water to produce hydrogen for upgrading, and efficient use, distribution and recovery of energy in combined energy cycles provides an economical and essentially energy sufficient process with the flexibility to be adapted for the recovery and upgrading of various low yield oil deposits.
