Abstract: Improved chilling apparatus for aircraft meal tray storage and/or serving carts utilizes a slidable tray type of bunker member for receiving dry ice or other cooling material. The bunker member is preferably of thermoformed plastic, is insulated on its bottom and sides, and has a channeled bottom which supports pieces of dry ice while permitting air to be circulated by a blower under the dry ice pieces as well as around and over them. At its downstream end, the bunker has an air flow turning surface and an air discharge opening through its bottom. At its upstream end, an opening directs return air which has passed over the meal trays to an angularly positioned blower located in the cart housing above the inlet end of the bunker.

Abstract: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a catalyst composite comprising from about 5 weight percent to about 95 weight percent of a silica polymorph consisting of crystalline silica, said silica polymorph after calcination in air at 600.degree. C. for one hour, having a mean refractive index of 1.39.+-.0.01 and a specific gravity at 25.degree. C. of 1.70.+-.0.05 g/cc and at least 5 weight percent to about 95 weight percent Ziegler alumina.

Abstract: A process and related apparatus for separating particulate solids from a stream comprising vapors and particulate solids passed in admixture through an elongated contacting zone. The stream is discharged at an angle to the vertical along the inside wall of a cylindrical disengagement zone. The solids separate due to centripetal acceleration and fall to the bottom of the disengagement zone.

Abstract: Substantially improved yields of 2,4,6-trialkylphenols result from alkylating a mixture of phenol and 2,6-dialkylphenol, the latter being a by-product of the alkylation reaction. This results flows from an unexpected synergistic effect accompanying transalkylation. The continuous method of making 2,4,6-trialkylphenol based on this property affords the highly desirable trialkylated phenols in high yield.

Abstract: Chilling apparatus especially adapted for airline food tray serving carts has a small blower at one upper end of the inside of the cart which exhausts air across a pan of dry ice or other cooling material removably positioned on an upper shelf of the cart. Spacer means in the cart enclosure prevent the trays stacked therein from blocking a vertical air flow passage at each end of the cart. Thus, the chilled air is directed downwardly from the pan over the inside wall of a door on the cart. The chilled air then passes horizontally over at least a portion of the trays containing items to be chilled and is sucked upwardly along the other inside end wall of the cart to the blower inlet duct. The apparatus is very light in weight and can provide sufficiently uniform cooling to the items on each tray which must be chilled when a container on each tray is being simultaneously heated.

Abstract: Improved mounting system for a vehicle seat having an air spring suspension includes a time delay valve means which cooperates with a linkage carried by the seat lower base to automatically position the seat upper base at the same vertical "mid-ride" position of the suspension regardless of the weight of the seat occupant. The system also includes an adjustable linkage which can be activated by the occupant before or after he is seated to reposition the seat upper base to a new "mid-ride" position of the suspension which can be adjusted in height relative to the floor of the vehicle in a range above or below a predetermined mid-range position. The system further includes a structure for providing a "protected" ride zone which has substantially the same movement range above and below the "mid-ride" position regardless of the occupant's weight or the adjusted position of the height adjustment linkage.

Abstract: An improved track fitting for anchoring an aircraft seat to a seat track has a threaded "anti-rattle" fastener for forcing a flanged top portion of a movement restricting shear pin against the top of the seat track to prevent rattle and wear due to aircraft vibrations. A pivoted lever which also functions as a cover for the fitting is mounted on the body of the fitting for lifting the shear pin against the force of a shear pin spring which normally urges the pin into locking engagement with one of the slots in a seat track. To prevent tampering by a passenger, the lever is rendered inoperable when the anti-rattle fastener is actuated. A leaf spring carried by the lever engages the body and prevents the lever from rattling due to vibration. The lever can lock the shear pin in its upper disengaged position as the seat fitting is lowered into the seat track and can then be released so that the shear pin will drop into one of the slots in the seat track automatically as the fitting is moved fore or aft.

Abstract: A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke contaminated fluid catalyst for use of the catalyst in a catalytic cracking reaction zone. The process comprises a high temperature coke combustion zone, a catalyst disengagement zone and an external heat removal zone comprising a shell and tube heat exchanger. A mixture of coke contaminated catalyst, and oxygen containing gas are contacted in the high temperature combustion zone. Catalyst is cooled by passing it through the shell side of the heat exchanger with a cooling medium through the tube side. The cooled catalyst is passed to the reaction zone. The catalyst is maintained in the cooling zone as a dense phase fluidized bed by passing a fluidizing gas into the bottom of the shell side. Steam is the preferred fluidizing gas.

Abstract: A hydrocarbon conversion process for light olefin isomerization is disclosed. The feed stream is admixed with the overhead vapor stream of a fractionation column, which also acts as a feed stream drying column. The resultant admixture flows through an isomerization zone, and the isomerization zone effluent is partially condensed and passed into the overhead receiver of the column. Uncondensed vapor from the overhead receiver is recycled to the isomerization zone as a hydrogen recycle stream and liquid hydrocarbons withdrawn from the receiver are charged to the top of the fractionation column as the feed stream to the column.

Abstract: Dehydrogenatable hydrocarbons are dehydrogenated by contacting them at hydrocarbon dehydrogenation conditions with a multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed ruthenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component maintained in the elemental metallic state, and of a rhenium component. An optional non-acidic multimetallic catalytic composite disclosed herein is a combination of a catalytically effective amount of a pyrolyzed ruthenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component which is maintained in the elemental metallic state during the incorporation of the ruthenium carbonyl component, a rhenium component, and an alkali or alkaline earth component.

Abstract: Mounting system for the back rest of a vehicle seat permits normal reclining action as well as two modes of forward movement. In a first mode, a slight forward force applied near the top of the seat back, such as about 10 lbs. or less, will pivot the top of the seat back forwardly several inches to facilitate access to the space behind the seat. The slight rearward force produced by an occupant leaning back against the seat back as he occupies the seat will then return the back to its normal upright position. A substantially larger forward force, such as one of about 25-35 lbs., can also be applied to the top of the seat back in a second mode to cause the back to "break-over" about 90.degree. and lie flat. The various movements are achieved by means of a channel-shaped quadrant member which overlies the back rest frame on one side of a seat, pivots on the back rest support shaft, and includes a long curved slot and a short curved slot.

Abstract: Alcohols may be obtained by an indirect hydration of olefinic hydrocarbons in which said olefinic hydrocarbon is esterified by treatment with an inorganic acid to form dialkyl and alkyl hydrogen salts. The esters are then hydrolyzed with water, the reconstituted acid is stripped by means of a stripping agent such as nitrogen gas, and the resulting alcohols and ethers are recovered. The alcohol production is separated from the dialkyl ether, the latter then being subjected to further treatment such as thermal decomposition and hydrolysis to form an additional amount of the desired alcohol. The reconstituted inorganic acid may be recycled for use as an esterifying agent without having to reconstitute the acid.

Abstract: A multi-step hydrocarbon conversion process for producing gasoline from propane or butane is disclosed. The feed hydrocarbon is passed into a dehydrogenation zone and the entire dehydrogenation zone effluent including hydrogen and light by-products is then passed into a catalytic condensation zone wherein the resulting olefins are converted into dimers and trimers. The condensation zone effluent stream is passed into a separation zone in which the dimers and trimers are concentrated into a product stream, with unconverted feed hydrocarbon and hydrogen being recycled to the dehydrogenation zone.

Abstract: Alkylated 5,6,7,8-tetrahydronaphthalenols are effective antioxidants for fuel oils, lubricating oils, greases, plastics, and rubbers over a wide temperature range. Di- and tri-alkylated tetrahydronaphthalenols are especially effective, with the di- and tri-isopropylated materials being preferred.

Abstract: A cogeneration system which produces electrical power through the use of an augmented Brayton cycle is disclosed. A pressurized air stream from an industrial source, such as a petroleum refinery, is heated by indirect heat exchange against a turbine effluent stream and is then depressurized in a turbine which drives an electrical generator. Preferably, a high temperature gas stream which also is simultaneously depressurized in the same turbine is admixed into the heated air stream before the air stream enters the turbine. A portion of the air stream may be heated in a supplemental combustion zone rather than by heat exchange.

Abstract: Conductive pigment-coated surfaces may be prepared by alloying a nonnoble conductive metal with an oxidizable material, admixing the alloy with an organic vehicle and a binder to form an ink followed by firing the ink in an oxidizing atmosphere containing about 20% by volume of oxygen at a temperature in excess of 1000.degree. F. If so desired, a vitreous frit may also be present in the mixture. The resulting ink will possess desirable characteristics such as increased resistivity to oxidation, and increased firing strength when the oxidizable material such as boron is present in the alloy in an amount in the range of from about 12% to about 25% by weight.
