Abstract: WALK-ABOUT WASHING APPARATUS               ABSTRACT OF THE DISCLOSURE      A vehicle washing apparatus of the type wherein a vehi-cle travels through the apparatus.  The apparatus features an up-right rotary brush mounted on a rigid swing arm structure which is pivoted on a reciprocable carriage that can be shifted back and forth a limited distance along a track substantially parallel-ing the path along which a vehicle moves.  Swinging of the arm structure and brush results chiefly from engagement between the brush and the end and lateral sides of a moving vehicle.  Shift-ing of the carriage occurs under power through the operation of a reversible motor whose driving direction is determined, according to the invention, by the angular position of the arm structure and brush.

Abstract: ABSTRACT OF THE DISCLOSURE             A focus detector includes apertured photodetect-ors which intercept a radiant beam.  Changes in focus dif-ferentially affect the amount of radiation impinging on the detectors resulting in corresponding changes in their signal output.  A videodisc system employing the detector moves a focusing lens to compensate for variations in the position of a target videodisc, so that a scanning beam is always accurately transmitted to a detector.  A dif-ference circuit connected to two photodetectors generates a driving signal to energize a lens-moving motor for shifting the focusing lens toward or away from the video-disc.

Abstract: MEANS AND METHOD FOR CONTROLLING        AN ABSORBER SYSTEM      (D#73,851-F) ABSTRACT OF THE DISCLOSURE           A control system controls an absorber system having two or more absorbers to achieve an optimum operating condition.  The components of feed solvent, effluent gas and feed gas to and from the absorbers are identified by type and quantity.  The control system then computes profits based on the relationship of the various components to each other for each combination of quantity of differ-ent components.  A first profit is stored along with the values of the absorber system parameters associated with that profit.  Subsequent profits are calculated for differ-combinations.  Each calculated profit is compared with the stored profit.  When a calculated profit is greater than a stored profit, the calculated profit is stored along with the values of the absorber system parameters associated with it.  The process continues until a cycle of operation has been completed at which time the stored profit is the maximum profit and the stored values are the values of the absorber system parameter necessary to achieve the maximum profit.  The control system controls the feed solvent and the feed gas in accordance with the stored values of the absorber system parameters.     -I-
