Abstract: Abstract:         A process and apparatus are provided for removing a first gas from a mixture thereof with a second gas. The gas mixture is passed through a sorbent bed having a preferential affinity for the first gas and comprising a microwave absorbent capable of absorbing microwave energy and the first gas is sorbed on the sorbent so as to produce a gaseous effluent which has a concentration of first gas therein below a predetermined maximum. Then the first gas sorbed on the sorbent bed is removed therefrom by application of microwave energy, at a temperature at which the microwave absorbent absorbs such energy and activates the first gas sufficiently to desorb the first gas, while passing a purge flow of gas in contact with the bed to flush out desorbed first gas from the bed. The bed is allowed to cool to a relatively efficient temperature for adsorption. The gas mixture is then again passed in contact with the bed. If two beds are used, one bed can be desorbed while the other is on-stream, thereby maintaining a substantially continuous flow of effluent gas.        The apparatus of the invention provides a sorbent bed assembly having a microwave energy generator positioned to direct such energy into a sorbent bed comprising a microwave absorbent capable of absorbing microwave energy for desorption of first gas from the sorbent bed.

Abstract: ABSTRACT OF THE DISCLOSURE      A suspended ceiling system including a main beam formed with a vertically extending rectangular window and a pair of cross beams intended to abut the main beam in alignment with one another at the window.  The cross beams, which are identical, have at each end a pair of longitudinally extend ing vertically spaced tongues integral with the web thereof, the tongues being spaced and laterally offset in opposite directions from the plane of the associated web to such degree that the diagonally measured distance between the upper edge of the upper tongue and the lower edge of the lower tongue is equal to the diagonal dimension of the window so that, when the tongues of the mated cross beams are inserted into the window from opposite sides to seated positions, the tongues of the cross beams mutually overlap one another for snug occupation of all four corners of the window opening.  To lock the parts in place the lower tongues are each formed with a downwardly extending hook projection which is in interfering engagement with the lower edge, or ledge, of the window, making the cross beams captive against longitudinal withdrawal from their seated positions.  The tongues are of substantially the same length, but the upper tongues are relieved along the tip portions of their upper edges to provide initial clearance with respect to the upper edge of the window, thereby to permit the hook projection on the cross beam to be hooked over the ledge of the window as a preliminary to the movement of the parts into seated condition.

Abstract: ABSTRACT OF THE DISCLOSURE Improvements are provided in detection devices for spotting over-heated components at the wheel frame of a railroad car moving on a rail. The detection device has a detector operatively associated with the rail to sense infrared radiation and includes subsequent analyzing electronics.          A rail switch is mounted at the rail to activate the detector and its circuitry at the time a wheel passes by.  The circuitry contains threshold value switches transmitting a detector signal to a memory display only when the signal is the analogue of an inadmissibly high temperature.  The detec-tor means is mounted below the bearing of the wheel passing by and the measuring axis of the detector means extends approximately vertically upward and parallel to the plane of the wheel passing by.  The improvement resides in the fact that the detector means comprises a first,bearing temperature detector for sensing a bearing temperature, and a second,wheel rim tempera-ture detector for sensing a wheel rim temperature.  The first bearing tempera-ture detector and the second wheel rim temperature detector are constructively combined in a common housing.  A single rail switch means is provided for actuating the first bearing temperature detector and the second wheel rim temperature detector.

Abstract: METHOD OF SEPARATING AROMATIC AND NONAROMATIC HYDROCARBONS IN MIXED HYDROCARBON FEEDS                      ABSTRACT        A process for separating aromatic and nonaromatic hydrocarbons which comprises a continuous solvent extraction - solvent decantation process.  The process is particularly well-suited for a hydrocarbon feed comprising hydrocarbon mineral oils as a nonaromatic component wherein the process provides improved stability of said hydrocarbon mineral oils, normally susceptible to thermal degradation and oxidation and, further, decreases the tendency of such oils to form sludge.  The process involves: (a) contacting such hydrocarbon feed in an extraction zone with an aromatic selective solvent, at a temperature of at least about 150°C, to provide an aromatic-rich solvent phase containing primarily aromatic hydrocarbons and solvent and a raffinate phase containing primarily nonaromatic hydrocarbons; (b) cooling the aromatic-rich solvent phase to bring about the formation of two phases; (c) introducing the phases of the cooled aromatic-rich solvent phase to a decantation zone and introducing therewith from about 0.5 to about 25.0% by weight of an anti-solvent for said aromatic hydrocarbon in said aromatic selective solvent to provide an aromatic-rich extract phase containing primarily aromatic hydrocarbons and a solvent phase containing primarily aromatic selective solvent and anti-solvent;          (d) removing anti-solvent from said solvent phase and recycling said solvent phase to the extraction zone of step (a); and (e) recovering the aromatic-rich extract of step (c) and the raffinate of step (a).
