Abstract: ABSTRACT         A coal-based heavy oil is refined so as to remove quinoline insolubles and provide a hydrocarbon product suitable for making carbon stocks by heating to remove the volatile components which have boiling points ranging from the initial boiling point of the heavy oil to up to at least 200°C and at most 270°C, thereby leaving a residual coal-based heavy oil, the residual coal-based heavy oil is mixed with a ketone-type solvent having a boiling point less than 200°C to form an insoluble precipitate (including quinoline insolubles) and a supernatent, the supernatent is treated to recover the ketone-type solvent, and the remaining hydrocarbon mixture is easily processed by vacuum distillation to produce a hydrocarbon product suitable for making carbon stocks.

Abstract: Laterally and Vertically Controllable Underwater Towed Vehicle Abstract A towed underwater vehicle that is laterally and vertically movable with respect to a towing vessel connected by a tow cable to the vehicle.  Such movement of the vehicle is obtained by the interaction of a horizontally and vertically movable point of attachment of the tow cable to the vehicle, horizontal and vertical planing surfaces provided on the vehicle, and appropriate stabilization of the vehicle.  Such stabilization is obtained by adding buoyant materials to upper portions of the vehicle, ballast to lower portions of the vehicle, use of adjustable ailerons or adjustable horizontal and vertical planing surfaces, or a combination of the preceding.  When the point of attachment between the cable and the towed vehicle is changed, the forces exerted by the cable on the vehicle are changed so that the planing surfaces of the vehicle present an increased frontal area to water flowing past the vehicle.  The increased frontal area struck by the water results in movement of the vehicle to minimize the frontal area.  Such movement of the vehicle carries with it the point of attachment to the tow cable and varies the position of the towed vehicle with respect to the towing vessel.  Such movement is in lateral, vertical, or in both directions.

Abstract: 22                48,327 ABSTRACT OF THE DISCLOSURE An  elevator  system  having  a  notching  floor selector which is notched or advanced by notching signals developed as the elevator car moves through the hoistway, to cause the selector to store information relative to the actual position of the elevator car.  The notching signals also  actuate  first  and  second  counters,  one  of which operates  a  non-volatile  memory.   The  memory  count  is compared with the count on the remaining counter, and when they are not equal a reset operation is initiated which includes resetting the notching floor selector and coun-ters to represent a predetermined terminal floor, and the generation  of  auxiliary  notching  signals,  all  without moving the elevator car.  When the memory and counter have the same count, the auxiliary notching signals are term-inated, and the floor selector system is back in synchro-nism with the actual position of the elevator car.

Abstract: Applicant:     Vaughan Co., Inc. Title:         High Head Centrifugal Slicing Slurry Pump ABSTRACT           A booster propeller is located at the inlet of a flared funnel leading toward arcuate inlet apertures in an end plate of a centrifugal pump casing.  Such propeller has radially projecting blades of generally right triangular cross section with bases formed of the broad trailing sides and broad bottom sides remote from the impeller; the hypotenuse side of each blade being a broad upper surface inclined relative to a plane perpendicular to the axis for propelling slurry toward the inlet apertures.  The pump impeller is received in a bowl capped by the end plate and has a circular shroud plate perpendicular to the axis with vanes or blades projecting toward the end plate and having cupped leading surfaces forming a sharpened edge.  Such blades are swept back in the area of the end plate inlet apertures for effective slicing of chunks or lumps of solid material in the slurry in combination with sharpened leading edges of the inlet apertures. The pump casing bowl has a semicylindrical wall portion closely encircling the impeller and providing a pressure-increasing zone for slurry accelerated outward before the bowl wall spirals volutely outward to the outlet conduit.

Abstract: CONTROL LINKAGE FOR TWO FUNCTION BALE PICKUP                    ABSTRACT OF THE DISCLOSURE A control linkage for a round bale wagon is disclosed wherein both the operation of the bale pickup mechanism to squeeze a bale of crop materiel for firm engagement between a pair of projecting arms and the operation to lift a bale so engaged onto the load bed can be controlled by a single control lever. The squeeze and lift operations are powered by separate hydraulic cylinders operatively controlled by respective control valves having three position spools, spring loaded to the central, neutral position.  The control linkage includes a cross link interconnecting the two respective control valves and a connecting link extending from a point on the cross link closer to the squeeze valve than to the lift valve, for connection to the control lever.  Movement of the control lever effects a movement of the squeeze valve spool to manipulate the squeeze function of the bale pickup mechanism before effecting a movement of the lift valve spool, which manipulates the lift function of the bale pickup; however, due to the spring loaded spools, the lift valve spool will return to the central, neutral position before the squeeze valve spool. A hydraulic system is also provided so that the squeeze function of the bale pickup mechanism can only be manipulated whenever the lift valve spool is in the neutral position.

Abstract: ABSTRACT     According to this invention, tape tension variations between supply and take-up spools are reduced using fixed guides for the tape.  These guides are located in the tape path between the turn-around idlers and the tape rolls.  The guides are positioned to create tape tension variations which are opposite to variations in the tape head span, thereby providing a cancelling effect.  Reducing the tape tension variation reduces the amount of tension necessary to maintain a working tension for contact with the transducing head, thereby decreasing head and tape wear and increasing tape life.

Abstract: A B S T R A C T            The invention relates to a method for separating gaseous elementary mercury from a gas in conjunction with a wet-gas cleaning process comprising a plurality of washing stages. The mercury-containing gas is treated with an aqueous washing liquid conducted in a closed cir-cuit, the liquid containing 0.1 - 300 mmol/l mercury (II) ions and at least twice this amount of ions having the ability of forming complexes with mercury (II) ions, the mercury in the gas being oxi-dized and absorbed in the washing liquid. The invention is charac-terized in that the treatment process is carried out in conjunction with a gas-cooling process effected after the last washing stage of the wet-gas cleaning process, to form a condensate for absorbing the halogens contained in the gas. The resultant condensate is trans-ferred to the washing liquid and the mercury (II) content of the washing liquid is maintained by contacting the washing liquid with an oxidizing agent for mercury (I) ions. The agent used to oxidize mercury (I) ions is preferably chlorine gas.

Abstract: ABSTRACT         A beam feedback synchronization system for optical sweeping systems is disclosed.  The system includes a multi-faceted rotating reflection mirror which acts on a collimated light beam such as a laser beam, to cause it to sweep periodically in parallel straight lines across a rotating photoconducting drum.          A circular reflector is positioned at a critical position between the rotating reflection mirror and the rotating photoconducting drum.  This circular reflector causes a portion of this light to be split off from the main beam and reflected back upon a photo-detection device which is positioned in close proximity to the rotating reflection mirror.  The electrical signals from the photodetection device are amplified and modified before being applied as periodic synchronizing feedback signals to the character generator from which the data information is emanating.
