Abstract: ABSTRACT         A system or displaying alphanumeric messages includes a unitary visual display device having a limited number of character display stations at each of which a character may be created in response to a set of signals applied to the character station.  A memory stores a plurality of complete message units which form a number of complete messages and some of the complete messages are multiple-message unit messages made up of a number of complete message units in a sequence.  The message units in a multiple-message unit message are automatically accessed from memory and displayed in a time-spaced relationship by the display device one complete message unit at a time.  The memory may also store complete message units having a stored message component and a real time message component.  A predetermined number of character stations are automatically reserved to display real time characters in a complete message unit having a stored and real time message component.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a vertical gas flue for a heat exchanger of the type having a hopper at the bottom end. The gas flue is defined by interconnected medium-carrying wall-forming gas flue tubes extending substantially longitudinally of the flue.  The hopper is also defined by interconnected medium-carrying and wall-forming hopper tubes.  The inclined hopper walls meet wall-forming tubes of the gas flue along a boundary edge near the top of the walls.  The tubes of the hopper walls are connected with gas flue tubes on the medium side.  In accordance with the invention, the gas flue has at least a pentagonal or cylindrical cross-section, the boundary edge extending over the entire periphery of the gas flue.  All the wall-forming tubes of the gas flue are bent at the boundary edge, such that they are directed outwardly from the gas flue wall, in the case of at least some of the tubes.  The tubes run parallel with each other within the hopper wall.  The advance in the art is that the invention allows application of the gas flue of the type mentioned above in a simple and inexpensive manner.

Abstract: ROW CROP HARVESTER GUIDANCE SYSTEM CONTROL CIRCUIT                Abstract of the Disclosure A row crop harvester guidance system control circuit comprises a control valve for actuating a hydraulic cylinder connected to the tongue of a pull type harvester responsive either to first and second row crop sensing units mounted on opposite sides of a crop receiving passageway of the harvester or to a manual override switch.  The row crop sensing units operate respectively a pair of sensor switches connected in circuit with the control valve.  To prevent simultaneous generation of signals by both of the sensor switches, a pair of relays are connected in circuit with the sensor switches and the control valve.  The manual override switch is connected in circuit with the relays and generates a control signal for operation of the hydraulic cylinder.  The control signal has priority over any contradictory signal generated automatically by either of the sensor switches.

Abstract: MULTIPLE CHAMBER CONTAINER HAVING     LEAK DETECTION COMPARTMENT                              Abstract A container (34) includes first and second chambers (40, 42) for the storage of two substances (44, 46) such as medical liquids.  The chambers are separated by a chamber-communicating assembly (61) which is selectively opened by an operator or mixture of the two substances and delivery to a patient.  A leak detection compartment (62) encloses the assembly (61) between the two chambers, including a periperhal channel (76) and ridges (80) on the assembly (61).    When seal integrity between the container wall sheets (36, 38) and the assembly (61) is less than complete, the leak detection compartment both prevents liquid in one chamber from entering the other through the leak pathway and also assures detection of the leak during the manufacturing operation.

Abstract: ABSTRACT          The invention is a process for the preparation of an aromatic hydrocarbon with a cyclobutene ring fused to the aromatic hydrocarbon which comprises, dissolving an ortho-alkyl halomethyl aromatic hydrocarbon in an inert solvent and pyrolyzing the solution of ortho-alkyl halomethyl aromatic hydrocarbon in the inert solvent under conditions such that the ortho-alkyl and the halomethyl substituents form a cyclobutene ring thereby forming an aromatic hydrocarbon having a fused cyclobu-tene ring.  The ortho-alkyl group has the structural formula (R')2-CH-, wherein R' is separately in each occurance hydrogen or a C1-20 alkyl.  The aromatic hydro-carbons with a cyclobutene ring fused to the aromatic hydrocarbon are useful in the preparation of monomers, which are then useful in the preparation of high performance polymers.     32,365-F

Abstract: ABSTRACT OF THE DISCLOSURE         Process and apparatus is disclosed for removing pollutants from a waste gas stream comprising culturing in a rotary biocontactor a biomass capable of assimilating the pollutants and producing harmless metabolites.  The waste gas stream is brought into contact with the biomass within the biocontactor.  The biocontactor includes a plurality of discs mounted for rotation within the biocontactor.  The waste gas stream in passing over the exposed biomass on the disc results in the pollutants being absorbed by the biomass.  In turn the biomass assimilates the pollutants and produces harmless metabolites.  The gas stream with a substantial percentage of pollutants removed therefrom and containing any gaseous metabolites is exhausted from the biocontactor.
