Title: Photographic exposure control system and method
Inventor: JOHNSON BRUCE K
IPC: G03B7/16
Filed: 1983-07-25
Granted: 1986-11-12
Abstract: ABSTRACT OF THE DISCLOSURE     A photographic exposure control system automati-cally classifies ambient scene lighting conditions as normal, backlit or forelit and then selects an exposure parameter signal program that is appropriate for the indicated conditions.  The system monitors a plurality of different portions of the scene area with a multi-sensor array that detects both subject range and ambient light intensity.  A comparison of range measurements identifies that scene area portion having the nearest subject therein as the subject area.  Ambient light intensity measurements of subject and non-subject areas are compared to classify lighting conditions and select a corresponding one of normal, backlit and forelit signal programs which control operation of system components to vary the ratio of ambient to artificial light contribution to exposure for the indicated lighting conditions.

Abstract: ABSTRACT         The invention involves a method for making powder metal forging preforms of high strength ferrous-base alloys in which the times and temperatures for reducing oxides, sintering, and carburizing are substan-tially reduced as compared to conventional techniques.          The method includes simultaneously sintering and carbur-izing the preforms in the hot zone of a sintering furnace at temperatures below 1093°C. (2000°F.) and for a period of time above austenitic temperature not exceeding about 35 minutes.  After carburizing the preforms are rapidly cooled to freeze the case carbon gradient obtained in the hot zone.

Abstract: A NEMATIC LIQUID CRYSTAL STORAGE DISPLAY DEVICE            Abstract A bistable nematic liquid crystal display cell is electrically switched between topologically equivalent, asymmetric horizontal states.  Switching is initiated by application of a symmetry breaking field such as a DC electric field of a predetermined polarity.  An AC electric potential is then applied across the cell to complete the switching cycle and maintain the state.  The cell includes upper and lower parallel substrates, upper and lower topographically textured tilt alignment surfaces on the corresponding substrates, and nematic liquid crystal material between the substrates.  In an active region of the cell, the tilt alignment surfaces form an equal reverse tilt boundary condition.  In an isolation region surrounding the active region of the cell, the tilt alignment surfaces are formed to have a parallel tilt boundary condition.

Augmentor wing flaps 28 are provided on the wings and fed with air from the low pressure compressor for providing additional lift and thrust from the wings.      In operation, at take-off the nozzles 24 are fully opened and all of the power produced by the power turbines 22 is used in driving the helicopter rotor for producing lift   In addition, the augmentor wing flaps 28 are directed downwardly to provide lift.  For forward flight the nozzles 24 are closed down reducing the power to the rotor and slowing it down, while at the same time generating forward thrust.  Additional forward thrust is derived from the flow of compressed air through the augmentor wing flaps 28.

Abstract: "Pitching Machine"                          ABSTRACT    This invention is intended to provide batters an oppor-tunity to improve their hand/eye coordination by batting at pitches which closely simulate actual game pitches in both speed and trajectory.  An arm member is moved in a generally horizontal plane so that one end of the arm member approaches a batter.  The end of the arm is fitted with a resilient ex-tension which, in turn, has a ball fixedly attached to its free end.  The arm may be raised, lowered, extended and re-retracted in any desired combination thereby moving the ball t oward, and past, the batter.  By varying the speed of the ball, its elevation in the vertical plane and its position in the horizontal plane, any desired pitch may be duplicated.  The ball may be positioned horizontally and vertically by cams and cam-followers which position the arm member in elevation and length.  Speed of the ball may be controlled by a motor/ gear arrangement which moves the arm toward the batter at any desired speed.  In its simplest form, the arm member is merely rotated about a vertical post member driven by the motor.  The invention may also include means for damping the ball after it has been batted and may be controlled by computer means.

Abstract: MEDICAL CONNECTOR SYSTEM            ABSTRACT OF THE DISCLOSURE          Disclosed  is  a  connector  system  for  medical applications  such  as  intravenously  introducing  medica-tion  into  a  patient.   In  intravenous  applications  a feeding  system  is employed  through  which  parenteral liquid flows into the patient intravenously via a needle attached at one end to the feeding system and having its pointed  end  inserted  into  the  patient's  vein.   The feeding system includes a port at the end of a conduit which  has  a  seal  associated with  it which closes  said port but is adapted to be penetrated by a second needle. This second  needle  is connected to a source of medica-tion  which  flows  through  the  second  needle  and  mixes with the parenteral liquid flowing  into the patient.  A cap member is secured to the port and it carries within a  cavity  the  second  needle  which  penetrates  the  seal when  the cap member is covering the port.   Because the cap is secured to the port, movement of the patient will not  result  in  the  second  needle being pulled  from the seal.   The  needle  is lodged  deep within the cavity so that if the cap is placed, for example, on the patient's bed, the needle will not directly contact bacteria which may be on the bed.  To avoid scraping material from the internal  conduit  walls  with  the  needle,  a potentially lethal  event,  the  cap member  serves  as  a  guide  which directs  the  needle  into  the  center  of  the  seal,  well away from the internal conduit walls.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for unloading layers of containers from a retort crate onto a conveyor assembly.  The retort crate is mounted on a movable carriage and has a movable bottom and an open top bounded by a top edge.  The con-veyor assembly includes a dead plate at one end having an inner edge adjacent the one end and an outer edge oppo-site the inner edge.  The apparatus can horizontally position the top edge of the retort crate adjacent the outer edge of the dead plate.   The bottom of the crate and a layer of containers can be raised.  The apparatus senses when the uppermost layer of containers is in an unload position, that is with the bottom edges of the containers in the uppermost layer generally level with the outer edge of the dead plate.   The bottom is stopped in its upward travel in response to the sensing of the uppermost layer at the unload position.  The uppermost layer of containers is swept from the retort crate onto the conveyor assembly.  The apparatus can function as an unloading or loading apparatus and is semi-automatic in operation.

Abstract: Abstract:    Metal oxides having a very narrow size distribution of micropores within the range of between 10 and 100 Angstroms can be prepared by reacting a water-soluble basic salt of a metal hydrate with an organic compound such as an acid halide in a specific manner.  The pore diameter of the metal oxide can be arbitrarily controlled within the range of the micropore size by changing the molecular chain length of the organic compound, treating the compound with an acid or calcining it at different temperatures. It is desirable that the narrow pore size distribution is centered within the range of 1 to 30 Angstroms, preferably 1 to 15 Angstroms when the metal oxide is used as a catalyst carrier.

Abstract: ABSTRACT          "Frequency Offset Correcting Circuit"         A second-order phase-locked loop (PLL) is provided following a demodulating section which is arranged to detect the baseband signals of orthogonally multiplexed QAM signals.  The second-order PLL, which is supplied with a baseband signal of a pilot channel from the demodulating section, includes a first and second control loops.  The first control loop is adapted to correct a static phase shift of the pilot channel signal, while the second control loop functions to correct an abrupt frequency offset of same.  The second-order PLL is further utilized to correct both static phase shifts and abrupt frequency offsets of data channels (viz., channels other than the pilot channel).  A third control loop is further provided which extends between the second-order PLL and the input of the demodulating section, and which has a function by which static or slowly changing frequency offsets of the channels are compensated.
