Abstract: ABSTRACT OF THE DISCLOSURE                   The combustion of carbon monoxide in the regenerator or a fluid catalytic cracking plant is controlled by adding a minute amount of a platinum metal compound or a rhenium compound to the circulating inventory of cracking catalyst during operation of the plant. The addition is accomplished by introducing a solution of the compound into a side-stream of the circulating inventory cooled preferably to about the boiling point of the solvent.  Excess solvent may be used as coolant.  The addition may be made to coked or to regenerated catalyst.  Suitable solvents include water and organic fluids boiling above about 140°F to about 600°F.  A particularly suitable side-stream apparatus is disclosed.

Abstract: ABSTRACT            In foundry manufacture of metallic castings it is customary to employ inserts to form elongate ducts whether rectilinear curved or branched and whether of regular cross-section or varying cross-section including enlarged cavities. Such inserts have mainly been formed of core-sand well known for its foundry use. Whilst being readily manipulated into required shapes core sand has several disadvantages including the problems associated with removal of processing gases during casting operation, removal of the insert without fracture, additional unwanted insert portions leaving unwanted internal or surface discontinuities or cavities later to be filled and machine ground. Instead a core insert is provided which has a wire formed outer tubular casing and an internal wire structure, the core insert being removable in stages firstly removing a central longitudinal wire, then any intermediate layer and finally uncoiling the outer tubular casing which has preferably previously been wound in such manner and of such diameter wire as to avoid so far as possible any exaggerated surface undulations.

Abstract: METHOD FOR PRODUCING SELECTED ALIGNMENT IN LIQUID CRYSTAL CELLS          Abstract of the Disclosure A method of treating the surface of substrates used in liquid crys-tal display cells so that the surface forces the alignment of the liquid crystal layer to be either parallel with the substrate wall or perpendicular to it.  The method includes the step of forming free radicals of either oxygen or fluorine in a radio frequency plasma and exposing the glass or tin doped indium oxide (ITO) substrate to the reaction products of the plasma in such a manner that electron or ion bombardment is avoided.  When oxygen radicals only are employed, the surface forces parallel alignment.  When the oxygen treatment is fol-lowed by exposure to fluorine free radicals, the surface forces per-pendicular alignment.  To provide strong parallel alignment in reflect-ing liquid crystal display cells having metal, glass or ITO surfaces, the method consists of producing an oxygen plasma as described above and introducing either a volatile organo-silicon or an organo tin compound into the plasma.  The organo compound is completely oxidized in the plasma and the reaction product, SiO2 or SnO2, is carried by the gas stream onto the substrate which is placed well outside the plasma region where it forms a thin coherent deposit on the metal.  To provide strong perpendicular alignment in display cells having metal, glass or ITO sur-faces, the method consists of the oxygen treatment followed by exposure to a fluorine free radical plasma formed from an unsaturated polyfluo-inated compound.  A polymeric film is formed on the substrate by the in situ polymerization of the active fluorine species in the plasma.

Abstract: TWO STAGE WASTEWATER FLOTATION      Abstract of the Disclosure:      In a first stage, a flow of wastewater is adjusted to near zero streaming potential by injecting a mineral acid into the wastewater.  The thus adjusted flow enters a basin where it is subjected to a decreasing gradient of small bubbles to form and separate off a first buoyant floc from the flow of wastewater.  The flow of wastewater than passes to a second stage.  In the second stage, a metal coagulant is injected into the wastewater, and the wastewater and coagu-lant enter a coagulation cell into which dense quantities of bubbles are supplied.  Buoyant composites of particulates, coagulant and bubbles are formed in the cell.  These compos-ites leave the cell together with the wastewater flow and enter a second flotation basin where a second buoyant floc is separated off.  The first and second floc combined have a higher solids content, have a lesser relative volume, and have physical properties such that valuable materials are more readily recovered therefrom than from a floc that would be formed if the wastewater were subjected tot he second stage only.

Abstract: DIGITAL WELDED CONTROL SYSTEM                    Abstract of the Disclosure A digital welder control system for controlling a portable gun welder of the type used in the automotive industry on an assembly line.  An 8 bit microprocessor is the main control element of the system.  The known cycle time of the microprocessor is used to generate a real time delay which in turn is used to generate a digital phase shift heat control.  RAM locations in the microprocessor are used to store medium constants of the welding sequence which were previously stored, in prior art controls, in the position of tap switches or thumbwheel switches.  The controller provides diagnostics for six common problems often encountered by welder control systems such as override timeout, half cycling, transformer temperature rises, a low water flow, a shorted SCR, and a change in the heat settings.  The controller also provides a maintenance interval counter and compensator control having a four-step stepper.  The stepper control is used to automatically increase the weld heat after a preset number of welds to compensate for electrode mushrooming.  The controller also checks the setting of address and data thumbwheels to prevent incorrect entries into the welding sequence.  The controller also permits entry of data only into RAM locations which are used in the normal sequence of the welder.  The controller also utilizes serial communication between a sequence module used to program the microprocessor and the microprocessor to economize on the number of drivers and receivers required and to reduce the power requirements of the controller.
