Abstract: ABSTRACT OF DISCLOSURE     Particulate solids are continuously discharged from a high temperature fluidized bed through a descending solids withdrawal line into a fluidized bed cooling vessel while controlling the solids discharge rate indirectly by regulating the cooling vessel pressure, preferably by means of a control valve which is used to throttle gag taken off overhead from the vessel. Fluidized solids may be discharged from the cooling vessel into a second vessel in which they are slurried in water and removed from the system through one or more pressure letdown valves.  Alternatively, the particles may be passed from the fluidized bed colling vessel into a lock hopper from which they are withdrawn periodically.

Abstract: Abstract of the Disclosure During echo suppression in a system utilizing a full echo suppressor, noise is typically inserted in the receive line of the near-end party to assure him that the line has not "gone dead".  The need for a separate noise source for this purpose in eliminated in a digital system by using the existing coded incoming signals on the line. Thus, during echo suppression the bits of the coded incom-ing signal are altered to provide a random noise signal of normal background amplitude which is then inserted on the receive line.  In an illustrative companded sign magnitude code embodiment, the sign bit is replaced by the least significant bit, the least and next-to-least significant bits are interchanged and the remaining bits are zeroed, thereby producing an unintelligible background noise signal of appropriate amplitude.                         - i -

Abstract: GASIFICATION OF HYDROCARBON FEED STOCKS          Abstract of the Disclosure Hydrocarbon feedstock is first vaporized in the presence of hydrogen and then the vaporized hydrocarbon feedstock together with excess hydrogen, is gasified to form an effluent gas consist-ing essentially of methane and aromatic hydrocarbons together with hydrogen and minor amounts of hydrogen sulfide. The process is suitable for the production of a pipeline gas having a heating value of approximately 1,000 BTU/SCF by further processing the effluent, after separation of the aromatic fraction and hydrogen sulfide from the gasifier effluent; the effluent is subject to cryogenic separation of the hydrogen with the hydrogen being re-cycled to the gasification step and the methane being discharged into a product pipeline. The overall process contemplates re-vaporization of the aromatic fraction separated from the effluent and regasification to extinction of this fraction. Preferred feedstock are crude oil, bitumen produced from tar sands, shale oil,liquid volatiles resulting from coking of coal, liquiefied coal resulting from solvating coal with a solvent and hydrogen, aromatic hydrocarbons, naphtha, gas oils, crude oil distillates, and crude oil residues.      It is contemplated that the gasifier effluent could be used as a feedstream for the production of a hydrogen-carbon monoxide synthesis gas, hydrogen, carbon monoxide or as a source of fuel to be burned in place of oil or other liquid hydrocarbons.

The energy emitted from the chamber through the end wall sums to form along and around the selected axis a beam-like pattern of controlled width, the beam width being controllable as a function of the offset distance and the energy wavelength.  In one embodiment, circular apertures which operate to emit spherical radiation patterns are formed in the chamber end wall.  In another embodiment, an annular aperture is formed in the chamber end wall concentric with the selected axis.

Abstract: ABSTRACT         An improved apparatus for the loading of pallets with tiers of cartons.  The apparatus of the present invention utilizes three star wheels, one to divide a feed line or single file of cartons into two rows and a pair of star wheels rotata-ble about axes normal to the path of the cartons in the two rows for varying the position of cartons on conveyors forming the tiers.  The tiers, after being formed, are stacked on a pallet.  The pallets are supported on an elevator to be lowered from the tier-forming station.  New pallets are introduced at the tier-forming station while a loaded pallet is being discharged from the palletizing machine.  The machine which forms the tiers is in an elevated position and each tier is formed in the tier-forming station by cartons fed from each side of the tier.  The tier-forming station is at one end of the machine and an elevator lowers the pallet as it is loaded with successive tiers which provides a machine capable of substantially increasing the rate at which cartons can be handled.  The tiers, as they are formed, are pushed from a stationary plate onto a moving plate which carries the cartons of the tier over the pallet and the movable plate is then retracted from beneath the tier placing it on the pallet or previously deposited tier.

Abstract: POSITIVE HOLD DIFFERENTIAL               ABSTRACT OF THE DISCLOSURE         A positive locking differential that functions to compensate for the difference in driving wheel travel which occurs when turning or traveling over uneven ground, while at the same time functioning to prevent wheel-slip when one wheel looses traction.  The differential comprises a spider-center cam assembly having four trunnions projecting radially from a center ring on each side of which is located a plurality of fixed driving clutch teeth.  The internal diameter of the spider mounts the center cam in such a manner that the same may be rotated a limited, predeter-mined distance.  The center cam is symmetric having cam lifts on each side which include rounded surfaces that provide anti-friction ramps for disengaging driven clutch members mounted on each side of the spider and center cam assembly.  The driven clutch members have clutch teeth which correspond to the clutch teeth on the spider and through which a driving torque is transmitted.  Dis-engaging cams radially inwardly spaced from the driven clutch teeth and rigidly attached to the clutch are adapted to mesh with the cams of the center cam member.  Enlarged sections and corresponding slotted portions disposed between the clutch members and the spider-cam assembly at spaced intervals maintain the clutch members in a disengaged mode during relative movement between the clutch members and the spider-cam assembly.  Suitable splined members are provided to receive the vehicle axle shafts to transmit the torque from the positive locking differential to the vehicle wheels.
