Abstract: ABSTRACT OF THE DISCLOSURE           In transversal computer tomography apparatus, in which the positioning zone in which the patient can be positioned is larger than the scanning zone in which a body slice can be scanned, due to incomplete irradiation of the body during examination reconstruction errors are liable to occur.  These errors can be reduced in that a sum of measuring values of a measuring series is formed and that difference between each sum and a maximum of all sums is determined, whilst in the case where at least one of the differences thus formed deviates from zero, a priori values are formed to complement the measuring values, so that for each beam direc-tion, the sum of the a priori values corresponds to the difference determined for this direction or measuring series, each a priori value for each time one direction being propor-tional to the length of a beam extending through the body out-side a scanning zone in this direction.  This length corres-ponds to the distance between two points of intersection of the beam and the edge of the body.  This edge being determined as the envelope of all beams which are tangent to the body inside the scanning zone, or as an extension of the envelope which is determined by interpolation.  The reconstruction of the absorption distribution inside the scanning zone is realized on the basis of the measuring values and the a priori values.

Granted: 1981-07-07
Abstract: ABSTRACT OF THE DISCLOSURE   A brake pedal assembly including a pedal lever which is pivotally attached to a housing, a plate pivotally attached to the pedal lever, a push rod attached to said plate  and a pulley arrangement. The cable has a fixed length with a first and attached to the pedal lever and a second end attached to the plate.  An operator input applied to the pedal lever moves the pedal lever in an arc about the pivotal attachment of the housing.  As the pedal lever moves, the cable length between the pulley mechanism and the first end increases while the length between the pulley mechanism and the second end decreases.  A decrease in the length of the cable between the second end and the pulley causes the plate to pivot with respect to the pedal lever.  The arcuate movement of the first lever and the pivoting of the plate are combined to provide a push rod with linear movement for actuating a force receiver.

Abstract: DECELERATION LEAN OUT FEATURE FOR ELECTRONIC FUEL MANAGEMENT SYSTEMS             ABSTRACT OF THE DISCLOSURE An electronic control unit for regulating the air/fuel  ratio  of  an  internal  combustion  engine  is disclosed.  The electronic control unit has an open loop calibration for  regulating  the  air/fuel  ratio that  is corrected with a closed loop correction signal developed by an integral controller.  The open loop calibration is a speed-density  based  schedule  which  is  combined  with corrections for  special conditions to account for  the operating  parameters  of  the  engine  at  any  instant. Included  in  these  special  condition  corrections  are provisions  for  increasing  the  air/fuel  ratio  upon  a deceleration sufficient enough to cause a rich air/fuel ratio breakthrough because of the EGR valve lag time.  A deceleration detector senses decelerations in excess of this predetermined amount by measuring the rate of change of the pressure in the intake manifold of the engine.  A fixed percentage increase in air/fuel ratio is switched into  the  open  loop  calibration when  the  deceleration exceeds the amount required for breakthrough.  The feature is additionally inhibited at low engine speeds and when the EGR valve is not operational.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for the field rearing of planktonic larvae of marine animals involving suspending a field culture enclosure in oceanic tidal waters, stocking the enclosure with larvae of a preselected species of marine animal, permitting the enclosure to orient in response to the tidal flow of water, screening out larger plankton from entry into the enclosure and filtering water leaving the enclosure to impede the escape of the larvae and food plankton.  The culture enclosure is suspended from flotation means and is equipped with a drop-rudder supported horizontally outwardly and spaced form the enclosure side.  The entry port has a plurality of deflection vanes to direct incoming water towards the enclosure periphery so that a substantially circular flow of water within the enclosure is achieved.  By withdrawing water from the enclosure bottom a down-welling combines with the circular flow to cause food plankton and larvae to accumulate near the center and top of the enclosure.  A filter bed over the enclosure bottom impedes the escape of larvae and food plankton while permitting moribund larvae and plankton, excretions and waste material to penetrate the bed and undergo bio-degradation thereby pre-venting the formation of an infectious bacterial scum on the enclosure bottom.
