Abstract: Abstract Disclosed is a signed multiplier for use in a data process-ing system that handles 2's complement operands. The signed multiplier operates to form a preliminary product independently of the signs of the multiplier and multipli-cand.  While the multiplication is in progress, the signs of the multiplier and multiplicand are checked.  For multiplications where either one of the operands (multipli-er or multiplicand) is negative, the preliminary product is modified by one or two correction factors.  The correction factors are multiples of the 2's complements of the oper-ands.  The correction factor or factors are added to the preliminary product to form the final product.

Abstract: BOOKSHELF COMPENSATING EXHAUST HOOD APPARATUS          Abstract of the Disclosure A bookshelf compensating exhaust hood includes an upper wall passageway for forming and redirecting an induction air stream into and through an exhaust chamber to an exhaust passageway, the upper wall passageway extends through the upper wall to a smooth curved reverse passageway redirects the air into a short slot which discharges a stream into the upper end of the exhaust chamber. A forward tilted filter is located in the exhaust chamber to form the back wall of the exhaust chamber and with the lower end spaced inwardly of the upper end and with the upper portion aligned with the induction air stream.  The filter is oriented to define an essentially right angle with the interior upper wall of the exhaust chamber.  The top wall of the exhaust chamber extends inwardly and upwardly slightly to the filter.  The induction air supply passageway is a relatively large passageway which has a depth which is a multiple of the depth of the slot.  The inlet expands slightly to the deflector and reverse passageway to the discharge slot.  The discharge slot includes a short extension of the deflector wall as an essentially flat wall which extends parallel to the top wall of the exhaust chamber.  For a gas fired unit, an exhaust duct is located to the backside of the hood for upwardly spaced alignment with flue duct of the equipment.  The spaced exhaust duct of the hood projects upwardly into the exhaust passageway for exhausting of the combustion gases and secondary air introduced between the flue duct and the exhaust duct.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention identifies methods and articles designed to circumvent metallurgical problems associated with hermetically closing an all cast iron nuclear waste package  by  welding. It  involves welding nickel-carbon alloy inserts which are bonded to the mating plug and main body components of the package.  The welding inserts might be bonded in place during casting of the package compon-ents.  When the waste package closure weld is made,  the most severe thermal effects of the process are restricted to the nickel-carbon insert material which is far better able to  accommodate  them  than  is  cast  iron.   Use  of nickel-carbon weld inserts should eliminate any need for pre-weld and post-weld heat treatments which are a problem to apply to nuclear waste packages.  Although the waste package  closure  weld  approach  described  results  in  a dissimilar metal combination, the relative surface area of nickel-to-iron,  their electrochemical  relationship,  and the presence of graphite in both materials will act to prevent any galvanic corrosion problem.

Title: Method and apparatus for manufacturing composite wood panels
Inventor: TAYLOR MICHAEL N

Granted: 1989-01-24
Abstract: ABSTRACT OF THE DISCLOSURE             An improved hot gas pressing system for use in manufacturing wood-based composite panels reduces in-press time substantially while reducing blistering, pitting, and warping in the final panel. Condensable steam as the preferred gas is injected into both faces of the mat after the press closes to an intermediate position compressing the mat to an inter-mediate density. After the steam is applied for a predetermined time period at the intermediate density quickly raising the mat temperature, a steam-through step is applied after which the press is closed to its final position. Steam is reapplied to both surfaces of the densified mat to maintain temperature further reducing cure time of the adhesive after which venting and vacuum steps are applied to both surfaces of the mat to reduce internal pressure and remove moisture from the mat prior to opening of the press.

Abstract: III. ABSTRACT      A flail auger assembly is disclosed which is useful for unloading semi-liquid material from a holding tank mounted on a tractor drawn trailer.  A rotatably mounted shaft extends lengthwise through the lower portion of the tank.  One end of the shaft penetrates the front wall of the tank enabling con-nection with the power takeoff of the tractor,  The second end penetrates the rear wall of the tank where it connects with the impeller of the discharge pump.  A plurality of flails extend radially outward at regular intervals along the shaft. The flails are pivotally attached via pins which secure them to brackets welded to the rotatably mounted shaft.  The pivotal axis of each flail allows it to aggressively attack the material in the tank while at the same time limiting the power drain on the tractor since the radius of effectiveness decreases as a function of increasing load,  The outward extending second end of the flails are twisted with respect to the pivot axes to impart both a chopping action and a rearward thrust to the semi-liquid material in the holding tank.  The rearward thrust forces the semi-liquid slurry to enter the discharge pump via a port in the lower rear wall of the tank.

Abstract: Abstract An  improved  system and process is provided in  a disc  drive for determining and for compensating  head/track offsets  when  a data (target) head is moved to a  new  data (target) track position.  Such disc drives typically include an armstack with transducer heads thereon,  either pivotally or  linearly mounted to move the transducer  heads  radially across  a  plurality  of memory discs in a  disc  stack.   A dedicated reference head is provided for scanning  dedicated servo tracks on a dedicated memory disc,  and a data head is provided on each data disc.         Head/track   position  offset  is  determined   by generating  an initial position offset signal indicative  of the  position  offset  between  the dedicated  head  and  an adjacent dedicated track while a  elected data head,  called the present head, is centered on its data track.         Head/track  position offset is  compensated  using this  initial  position offset signal in conjunction with a command signal including a track count to a dedicated target track,  to  generate  a velocity profile and  servo current commands used to achieve movement of the dedicated head to a position  from which it may be track centered at the  target track  position.   Thereafter any offset between the  target head and its target track is used to center the target  head on its target track.
