Abstract: The disclosure relates to a process for purifying crude, concentrated wet-processed phosphoric acid. To this end, the disclosure provides: (a) for the organic solvent to be mixed with the starting product in a ratio by volume of more than 4:1 to effect the extraction in a single process step-from the crude wet-processed phosphoric acid-of a quantity of phosphoric acid necessary for 40 to 70 weight % of the P2O5 used to go into the organic phase, and for the resulting aqueous phosphoric acid raffinate to contain at most 28-32 weight % P2O5, and for the organic phosphoric acid solution to be separated from the phosphoric acid raffinate; (b) for the separated organic phosphoric acid solution to be scrubbed with a quantity of scrubbing solution corresponding at most to 5% of the volume of the phosphoric acid solution; for the scrubbing solution to be recycled into stage (a), and for purified phosphoric acid and phosphate salt solution, respectively, to be recovered in known manner from the scrubbed phosphoric acid solution; and (c) for the aqueous phosphoric acid raffinate produced in stage (a), if desired after prior removal of residual solvent therefrom, to be directly utilized or subjected to known purifying treatment.

Abstract: Solids are withdrawn from a pressurised reactor by passing the solids from the reactor to a stripping vessel maintained at a pressure approximately equivalent to the pressure in the reactor wherein the solids are contacted with a volatilised liquid to displace gases. The stripped solids are then passed through a conduit containing valve means into a lockpot pressurised and the volatilised liquid to a pressure approximately equivalent to the pressure in the stripping vessel. The solids-free section of the lockpot communicates with a condenser vessel pressurised with the volatilised liquid to a pressure approximately equivalent to the pressure in the lockpot. After the solids have been passed into the lockpot, the valve means is closed and the volatilised liquid in the condenser is condensed thereby decreasing the pressure in the condenser which simultaneously results in a decrease of pressure in the lockpot. Depressured solids are then removed from the lockpot.

Abstract: A priority circuit handles requests by three components of a data processing system for access to several resources of the system that can be accessed one at a time on each operating cycle of the system. A logic circuit receives requests by the requesters (30-32) and grants access (64-66) to one requester on a priority basis. The logic circuit has means (39, 62, 63) for establishing a particular priority sequence, and the priority circuit includes means (69,72,73) for stepping the logic circuit through a cycle of different priority sequences. In a repeating cycle of these steps, each requester is given the highest priority at least once. The stepping means (72) is responsive to a control code to establish a particular stepping sequence. In a longer sequence, the lowest priority requester is given the highest priority once and higher priority requesters are given the highest priority several times so that in a complete cycle of steps the requesters have a different relative priority. In shorter cycles, the lowest priority requester is still given highest priority once and the higher priority requesters are given highest priority a few times so that in the shorter cycles the lowest priority requester has a higher relative priority. The priority circuit also includes means (48-53) for matching a request for a resource with the availability of the resource so that a requester contends for priority only if the resource is in fact available.

Abstract: A novel color selection electrode assembly is utilized in screening a pattern of phosphor areas upon the faceplate of a color cathode ray tube. The faceplate, which is formed of a material having a predetermined temperature coefficient of expansion, has registration affording means. The aforesaid assembly comprises an auxiliary mount formed of a material having a temperature coefficient of expansion greater than that of the faceplate and has a central opening of such span as to enable the mount to surround the periphery of the faceplate. Index bosses, cooperable with the faceplate registration affording means, are detachably secured to the mount. A planar metal foil having a predetermined pattern of apertures and formed of a material having a temperature coefficient of expansion not greater than that of the mount is secured to the mount. The index bosses cooperate with the registration affording means on the envelope to permit repeated precise registrations between the foil and the faceplate to facilitate screening of the phosphor pattern as well as to facilitate mating of the electrode assembly to the faceplate. Finally, the invention contemplates a method of utilizing the electrode assembly for screening a phosphor pattern as well as methods of making a color cathode ray tube having such an electrode assembly.

Abstract: @ A base coat applicator utilizing an in-feed chute which provides supply of cans which are mounted on mandrels for application of base coat material by applicator wheels. The mandrels are rotated so that surface speed of the cans matches the applicator wheel speed to prevent smearing. Independent control of the inventory production speed of the base coat applicator machine and the applicator wheels allows any desired num<sub>-</sub> ber of base coat layers to be applied to the cans. Two applicator wheels are used to reduce surface speeds to prevent misting and slinging of base coat material from the applicator wheels and can surfaces. The applicator assembly is automatically withdrawn when the supply of cans is not present and can be manually withdrawn by the operator to prevent application of base coat material to cans or empty mandrels. Disk transfer unit is utilized to transfer the coated cans to a deco pin chain.

Abstract: In an MOS integrated circuit device, the level of the back-bias voltage (-Vbb) which is generated by a built-in back-bias generation circuit (Vbb-G) and is supplied to a semiconductor substrate is changed by undesirable leakage current flowing through the semiconductor substrate. The leakage current is not constant but becomes relatively small when a main circuit formed on the semiconductor substrate such as a dynamic RAM is not operative, and relatively great when such a circuit is operative. To reduce the change of the back-bias voltage resulting from the change of the leakage current, the back-bias voltage generation circuit (Vbb-G) has an output capacity of a plurality of levels. The output capacity is increased in response to an operation control signal of the main circuit. The level change of the back-bias voltage generation circuit (Vbb-G) can further be reduced by providing a level detection circuit (VLD) for detecting the level change and a feedback circuit for controlling the back-bias voltage generation circuit in accordance with the output of the level detection circuit (VLD)
