Abstract: ADPCM ENCODER/DECODER WITH SIGNALLING BIT INSERTION     Abstract of the Disclosure In an ADPCM transmission system, signalling frames of an incoming multiplexed PCM signal are identified and signalling bits extracted therefrom.  During each signalling frame, an ADPCM encoder/decoder is controlled by the signalling frame signal to operate entirely for 3-bit ADPCM, instead of the regular 4-bit ADPCM, to which 3-bit ADPCM the extracted signalling bits are added for transmission.  The deliberate alteration from 4-bit to 3-bit ADPCM at the encoder and decoder of the system in each signalling frame ensures proper adaptation and consequently no loss of tracking between the encoder and the decoder.

Abstract: ABSTRACT A color TV imaging apparatus has a color TV imaging device which generates a multiplex color TV video signal by means of a photoelectric transducer section equipped with a color separation stripe filter.  A first bias light supply device is located in a front portion of the imaging device where the transducer section is formed, in order to apply first bias light which reduces deterioration of color reproducibility of a dark scene.  Disposed in a rear portion of the imaging device is a second bias light supply device which applies second bias light to the transducer section which reduces afterimage.  The quantity of the first bias light is predetermined to be smaller than that of the second bias light.

Abstract: ABSTRACT OF THE DISCLOSURE  .          A backgauge device for a metal working machine such as a shearing machine or press brake includes a beam member supporting a work stopper for butting against a workpiece.  The movable body supporting one end of the beam member which supports the work stopper, and the movable body supporting the other end of the beam member, move as one body in the forward and backward directions.  One edge of the beam member is supported in a horizontally rotatable manner by one movable body, while the other edge of the beam member is supported in a longitudinally slidable manner by the other movable body.  Means for tilting the beam member forwardly or backwardly as needed are provided.  Separate drive devices drive the left and right movable bodies.  The construction is such that it is unnecessary to synchronize and control each individual left and right movable body during movement.

Abstract: ABSTRACT OF THE DISCLOSURE         A lathe for cutting a spiral strip of veneer from the surface of a log includes motor-driven mechanisms for adjusting the knife blade pitch angle and edge height, and for moving a pressure head relative to the knife to adjust the vertical gap and horizontal gap between the knife edge and the roller bar, and provides sensors for determining the actual positions of movable elements of the lathe, thus enabling computer-controlled adjustment of the movable elements of the lathe during lathe operation.        A knife clamp of the lathe includes a plurality of separate clamp segments for pressing against different portions of a knife bar to hold it firmly, resulting deformation and rocking of the knife bar.  fluid-pressure-biased bearings eliminate looseness between relatively movable parts of the lathe, reducing the amount of variation of thickness in veneer produced using the lathe.  Veneer thickness is controlled by monitoring cumulative movement of the lathe spindles and the main feed carriage.

Abstract: Abstract of the Disclosure A hemapheresis system and method in accordance with the invention comprises a stationary closed housing concentric about a central axis and a feed system that moves blood upwardly from the housing lower end toward an outlet port adjacent a substantially closed upper end. Within the station-ary housing is a double walled rotor concentric with the housing and rotatable by magnetic means within the housing on sealed end bearings.  The space between the rotor walls defines a centrifugation gap into which whole blood is passed and within which centrifugal separation takes place as the rotor is spun at a relatively low rate.  Whole blood also seeks to flow upwardly in the space between the rotor and housing, but this path is arranged to have a substantially higher flow impedance, so that the preferential path is within the centrifugation gap. At the upper end of the rotor, lighter matter such as plasma rich in platelets passes continuously inwardly to a central lengthwise passageway leading to an outlet port coaxial with the central axis, while heavier central matter flows through apertures in the outer rotor wall to the upper outlet port.  In one example the differential impedance is established by housing and rotor configurations which diverge outwardly with compound curvatures, and with the space between rotor and housing leading to a closed end. In another example the housing-rotor space is of restricted cross section and an opposing flow of compatible fluid is introduced in an intermediate region of the flow path.  These systems are biologically closed and permit continuous return of packed cells to a donor as plasma is collected.

Abstract: ABSTRACT OF THE DISCLOSURE:      A  contact printing system produces photopatterned planar workpieces, such as printed wiring boards, with polymerized patterns on photopolymer coatings of precisely controlled thicknesses from a few microns to at least .003 in., with the workpieces ready for development by washing out unpolymerized portions.  Mesh screens deposit the initial polymer coatings, on the work piece and preferably also on a phototool image bearing surface, so that two layers are merged into one.  A clamshell fixture permits the layers of pastelike consistency liquid photopolymer to be sandwiched in precise registration for photoexposure from an U. V. lamp radiation source.  An operator can prepare one workpiece as another is being photoexposed.  A second exposure chamber permits preexposure of the layer on the phototool with one surface exposed to air to permit partial polymerization through its thickness, so that when merged onto the workpiece layer in liquid to liquid bubble free contact, wiring traces and through holes are covered with polymerized polymer of controlled thickness.  Boards are photoexposed on both sides before development, low energy is used and operator controlled steps are provided to produce high speed production of up to 60 double sided workpieces per hour.
