Abstract: IMPROVED PROCESSING OF HIGH NORMAL PARAFFIN CONCENTRATION NAPHTHA FEEDSTOCKS             ABSTRACT OF THE DISCLOSURE Normal paraffins present in high concentrations in light naphtha streams are separated from non-normal paraffins in a four or more bed adsorption system employing, on a cyclic basis, the processing steps of (1) cocurrent purge/adsorption, (2) cocurrent feed/adsorption, (3) countercurrent purge and (4) countercurrent displacement.  A processing sequence is employed wherein the cocurrent purge/adsorption and countercurrent purge steps are carried out on a discontinuous basis, while cocurrent feed/adsorption and countercurrent displacement steps are carried out in overlapping sequence.  Control means are provided to assure that the high normal paraffin-containing hydrocarbon feed gas and stripping gas are passed to the appropriate beds for said cocurrent purge/adsorption and countercurrent purge steps on a non-continuous basis, said feed gas being continuously fed to a mix drum for mixture with countercurrent purge effluent before removal for use in said cocurrent purge/adsorption step and in said cocurrent feed/adsorption step of the overall four-step process.

Abstract: Abstract A process is described for coprocessing coal and a heavy hydrocarbon, such as bitumen from tar sands or heavy oil.  A slurry of the heavy oil and coal is passed through a confined hydrocracking/hydrogenation zone in the presence of hydrogen sulphide as the sole catalyst. The effluent emerging from the zone is separated into a gaseous stream containing a wide boiling range of mate-rial and a slurry stream containing heavy hydrocarbons and unreacted coal.  This process permits maximum yields from both coal and bitumen, while suppressing coke for-mation during coprocessing.

Abstract: ABSTRACT OF DISCLOSURE     A centrifugal pump utilizing laminar action induced by a vaneless impeller and having a minimal drag front plate which cooperates with the circular rotor. The smooth surface of the concave face of the circular rotor has no protrusions or vanes and approximates an Archimedian curve.  Material entering the intake port of the front plate is diverted about the rotating impeller and redirected in an outwardly direction along the minimal drag interior surface of the front plate to the discharge port of the output housing.  The narrowing of the interior surface of the front plate in a radially outward direction with respect to the concave face of the impeller helps the pump to maintain a constant volumetric flow rate. Inasmuch as the "redirecting" of the incoming material stream follows an approximate Archimedian spiral, the pressures applied against the impeller and the forces acting centrifugally on the material stream join to produce the optimum imparting of kinetic energy to the material stream for the particular impeller speed. As a slurries pump, the vaneless design permits any particulate size that can clear the discharge port of the pump to safely transit through the pump without maceration or undue agitation.  As cavitation is totally absent, the pump can easily handle the movement of fragile, volatile or gaseous materials and can be operated over a wide range of speeds, matching desired feed without undue loss of efficiency.  Lacking vanes, the impeller offers very low starting torque under a loaded condition.

Abstract: COUPLING MECHANISM FOR QUICK         ATTACH/DISCONNECT OF A MISSILE CONTROL FIN               ABSTRACT OF THE DISCLOSURE           A coupling mechanism for quick attach/disconnect of a control fin to a missile which does not require the use of a separate tool to make the attachment.  A first coupling member 24 is mounted on the control fin actuator rod 16.  A force regulating means comprised of a spring 28 and retainer bracket 58 are attached to the first coupling member.  A second coupling member 26 and a pivotable lever arm 28 are formed as part of the control fin.  When the second coupling member is loosely fitted upon the first coupling member, rotation of the lever arm will engage the force regulating means thereby deflecting the spring 28.  The reactive force of the control fin, and causes the second coupling member to firmly and securely engage the first coupling member. A means is provided to lock the lever arm in place so as to retain the first and second coupling members in the firmly engaged position even through extreme aerodynamic maneuvers.  The lock is easily disengaged manually should it be necessary to remove a control fin from the missile.

Abstract: ABSTRACT OF THE DISCLOSURE An elevator system in which hall calls from an independent inconspicuous riser  (IR)  are handled by the same dispatcher as hall calls from the normal hall call riser.  Each floor of the building  is  assigned its  own unique timing scan slot position for detecting normal hall calls, with the number of scan slots being at least twice the number of floors in the building.  IR calls appear in scan slot positions for floors which are not in the actual building, and the dispatching function treats the building as though it had twice its actual number of floors.  A car on IR duty translates its advanced car position into the imaginary  portion  of  the  building,  before  sending  its advanced position signal to the dispatching function.  When a car on IR duty receives an assignment from the dispatch-ing function, its associated car controller translates an assignment for a fictitious floor to an actual floor of the building, and it utilizes its actual advanced car position in the process of serving the IR call.

Abstract: A method of and a furnace assembly for bending glass sheets. Glass sheets (6) are conveyed in bending moulds (5) supported by cars (4) along an upper transport run (2) periodically from one heating section (10) to another. In the final heating section, temperature is risen so high that a glass sheet bends by the action of heat and gravity to conform with the surface of the mould. Thereafter, a car (4) together with a bent glass sheet is lowered onto a lower run (3) and returned to the outset of a furnace (1). On cooling, the glass sheets on said lower run emit heat to the glass sheets on said upper run through the open bottom structures of cars (4). The weight and heat capacity of the cars have been made as low as possible by removing the side and back walls thereof, whereby only the front or leading walls (8) provide locking walls between sections (10) successive in the longitudinal direction of the furnace.
