Abstract: METHOD OF CASING-IN BOOKS            Abstract A method for bookbinding on a continuously-moving, constant-speed conveyor belt operation with the case or back-strip being centrally located on the axis of motion.      As the case is formed between opposing rotary irons, glue or paste is then applied to the upper insides of both sides of the case.  A book block is next dropped on one side of the case, the book block is aligned to register with the case; and the other side of the case is folded over to fasten to the upper side of the book block to form the book and prepare it for pressing and crimping of the building-in operation, without any interruption of the motion of the book along the conveyor system.

Abstract: ABSTRACT          APPARATUS FOR FEEDING A WIRE FROM        A WIRE COIL TO A PROCESSING STATION       Apparatus is described for feeding a wire from a wire coil to a processing station.  When wire is taken from a coil and fed to a processing station, because of the tension imposed on the wire, the wire end carries out uncontrolled movements which in arc welding are known as "pig-tailing" effects.  In order to obviate such uncontrolled movements of the wire after issuing from conventional guide means, in the present wire guide apparatus the wire is guided with a radius of curvature r which is equal to the radius of curvature which the cylindrical spring formed by the cylindrically wound wire has in its relaxed state.  The wire guide apparatus comprises a guide tube which is joined tangentially to the coil housing and which is constructed with a slightly curved shape.          Connected to the guide tube is a mouthpiece which has a curved tubular duct the radius of curvature of which is equal to the radius of curvature r.  The outer diameter of the cylindrical reel on which the wire is wound is preferably greater than the inner diameter of the relaxed cylindrical spring constituted by the wound wire.     Figure 1.

Abstract: ABSTRACT OF THE DISCLOSURE            The particles of a magnetically stabilized fluidized bed move continuously transverse to the flow of a gaseous or liquid fluidizing fluid.  The velocity profile of the particulate bed of this process has greater uniformity when the bed is operated at increased magnetic fields and lower superficial fluid velocities, lower bed tilt angle, lower average solids velocities or a combination of each.  A more uniform velocity profile can also be obtained using a properly designed weir.          By appropriately adjusting the magnetic field, the bed tilt angle, the average solids velocity, the superficial fluid velocity and weir height, essentially uniform velocity profiles and bed height profiles can be obtained.     It is found additionally that the bed par-ticles have increased fluidity when the bed is operated at or substantially near the locus of transition between the bubbling and stabilized regions of the bed, i.e., such that the  ratio of the difference between the transition velocity and the operating velocity to the difference between the transition velocity and the normal minimum fluidization velocity ranges between -0.1 and +0.5.     In another preferred embodiment the entering fluid has a velocity component in the direction of solids  flow,  i.e.,  the  transverse  flow direction.

Abstract: FLASH TANK CONSTRUCTION                        ABSTRACT          A flash tank, and method of flashing steam utilizing the tank, result in minimum foam generation so that the outlet steam remains uncontaminated.  Feed fluid fed into the interior of the tank is positively prevented from splashing into the liquid seal provided adjacent the liquid outlet from the tank.  This may be done by directing the feed fluid upwardly when introduced into the tank, and providing a liquid holding tank externally of the flash tank, feed fluid impacting upon a deflecting member and then the conically downwardly tapering walls of a bottom portion of the tank. Another alternative is to feed the feed fluid down-wardly into the tank to impact upon a conical deflecting member so that there is minimum loss of momentum of the feed fluid, and again it impacts upon the conically tapering walls of the tank bottom portion.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed are two embodiments of a dual valve useful down-hole in well tubes to shut off flow up the tube and open a wall flow passage to the well annulus through which well killing fluid may be pumped.    A ball valve is used to shut off formation upflow, and a cooperating sleeve valve above controls flow through the wall flow passage.  One embodiment uses a pressured bellows to determine well annulus pressure and to operate a pawl latch releasing a com-pressed spring to operate the valves.   Another embodiment uses a differential piston area to de-termine annulus-tube differential and move against a spring to operate a collet latch releasing a compressed spring to operate the valves.    Operation differential pressures may be varied for either embodiment, and both may be reset to operate again without retrieval from the well.

A communication processor having a plurality of buffers,  a memory shared by both the dispatcher processor and communication proces-sor, and an interface between the communication processor and the elevator cars, cooperatively control the flow of information.   Car  status  information,  prepared  by  the elevator cars, is sent to the dispatcher processor via the interface, buffers and shared memory.  Car mode information prepared by the dispatcher is sent to the elevator cars via the shared memory, buffers and interface.  A semaphore access arrangement speeds up access to the shared memory, and interrupts control transfer of information between the buffers and interface.  In the communication process, the dispatcher processor only loads and unloads the  shared memory, and the communication processor loads and unloads both the shared memory and the buffers.

Abstract: Abstract An improved liquid hydrocarbon feed method is disclosed wherein substantially all of the liquid is converted to mist sized particles over a wide angled dispersion pattern without a concurrent shroud of steam or water.  Such dispersion promotes vapor phase catalytic reaction between hydrocarbon vapors and fluidized catalyst in a reaction time of 1 to 3 seconds.  In a preferred form, the liquid feed is introduced into the transition section of a riser reactor.  The misting nozzle is characterized by a swirl chamber to which the full hydrocarbon feed is supplied for centrifugal rotation by vane members and the flow is released through a reduced area orifice having a short throat to maintain a low pressure drop through the nozzle and a cylindrically confined stream flow into the riser reactor produces a wide angled conical dispersion pattern.  Introduction of such a hydrocarbon dispersion into the reactor riser at high flow rate is maintained so that the liquid is substan-tially instantaneous vaporized.  Coking of the feed nozzle is thus avoided without requiring assistance of steam or water flow therearound.  Generation of misted hydrocarbon particles without steam or water substan-tially improves the economics of processing the resul-ting fluidized catalyting cracking products distilled from the evolved vapors by reducing sour (acid) water disposal.         Coking in the feed nozzle is avoided by maintaining high liquid velocities in the nozzle.  The large open area of the ports and exit orifice minimize the opportunity for physical plugging of the nozzle by coke or other foreign materials.  Short straight cylindrical flow from the orifice allows the nozzle to be recessed out of the flowing catalyst stream. This keeps the nozzle cooler and minimizes mechanical ero-sion of the nozzle by the heated catalyst.
