Abstract: LOGIC STATE ANALYZER                            Abstract A general purpose logic state analyzer selectively stores, formats and displays a digital signal representing a sequence of data states in-put thereto and provides a graphical display of the stored data states and a count of selected events occurring intermediate to the occurrence of the data states stored.  Selective storage of the input data states is provided by comparing the input data states to a preselected sequence of first qualifier state conditions and enabling the storage of input data states in response to the satisfaction of the preselected sequence. Storage is further qualified by storing only data states which indi-vidually meet one  of a preselected set of second qualifier state conditions.  Selective formatting of the stored data states is provided by converting the stored data states in response to selectable assignments of contiguous sets of bits of each stored data state to logical fields, a selectable concatenation of the logical fields, and to radicies selected for each of the respective logical fields.  The converted stored data states can be displayed as a formatted listing or as a graphical display.  In the graphical display the stored data bits corre-sponding to a selected logical field are interpreted as a binary magnitude and plotted as the ordinate and the chronological storage location is plotted as the ordinate and the chronological storage location is plotted as the abscissa on a cartesian coordinate system.  A count of selected events is obtained from the contents of a binary counter and stored in a second memory in parallel with the storing of each data state.  This counter can be incremented selectively in response to either an internal clock or in response to the detection of an input data state satisfying a selected count-qualifier state condition.

Abstract: FLUID PURIFICATION SYSTEM               ABSTRACT        A fluid purification system for performing filtration of particles from a feed liquid by a tan-gential flow of the feed liquid over a membrane surface. In one embodiment, the purification system includes a filter cartridge contained within a filter housing having ports permitting ingress and egress of feed liquid and filtrate.  The cartridge includes a filter element hav-ing a layered construction with a thin flow channel be-tween the layers.  One layer of the filter element is formed of a sheet of impervious material defining one wall of the thin flow channel.  Another layer of the filter element is spaced from the one layer and formed of a sheet of permeable membrane material and defines another wall of the thin flow channel.  The spacing between the walls of the thin flow channel is maintained by a sheet of reticular material that provides turbu-lence in the thin flow channel to promote cross flow filtration.  The filter element is formed into a pleated, cylindrical shape with a flow axis parallel to the pleats.  The sheet of impervious material may be provided with a limited number of pores of sufficient dimension to permit intermittent entry of feed liquid along the thin flow channel to linearize the pressure along the flow channel without a proportionate decrease in mass flux.  In another embodiment, the purification system is adapted for dialysis and/or diafiltration by modify-ing the cartridge and filter element to include another flow path for dialyzate.  A second thin flow channel is formed by the addition of another layer of impervious sheet material,  Both flow paths share a common membrane boundary.

Abstract: REVERSIBLE GEROTOR PUMP     ABSTRACT OF THE DISCLOSURE            A reversible gerotor pump is shown which delivers a lubricant in a predetermined manner regardless of direction of rotation.  The reversibility is provided by an eccentric collar having a cylindrical opening encircling the pump rotor and which is rotatable through a 180° arc by frictional engagement with the rotor.  To ensure this frictional engage-ment is greater than the frictional engagement between the collar and an adjacent stationary face plate which opposes rotation of the eccentric collar, the surface of the collar in facing engagement with the plate defines slight protrusions projecting therefrom.  The protrusions abut the plate for a limited surface engagement therebetween and therefore provide limited frictional engagement.  In this manner the friction between the collar and the stationary plate is minimized and the eccentric collar is relatively free to be rotated to either of two extreme positions within the 180° arc depending upon the direction of the rotation of the rotor.

Abstract: BINARY INTERPOLATOR FOR ELECTRONIC MUSICAL INSTRUMENT        Abstract of the Disclosure A binary interpolator circuit is embodied in an elec-tronic musical instrument for producing a relatively smooth, inaudible transition between steps of different amplitude in a stepwise   advancing or decreasing waveform, such as an en-velope signal for a note from a percussive type instrument or voice such as a piano.  The binary interpolator circuit includes a counter circuit for producing a sequence of stepwise changing-binary coded signals and a combining circuit for combining the interpolating signals, in the sequence produced, with a binary coded scaling signal corresponding to the amplitude difference between the two points in the stepwise changing waveform between which interpolation is desired.  A comparator circuit compares the interpolating signals, in the sequence produced, with the scaling signal and produces an output control signal for indicating whether the binary coded numbers corresponding to the respective interpolating and scaling signal are equal.          A control circuit is responsive to this control output signal for respectively allowing or inhibiting the production of the interpolating signals.  In a preferred embodiment, multi-plexing and demultiplexing circuits are provided for serially multiplexing a plurality of waveforms to be interpolated  and simultaneously serially multiplexing a plurality of interpolating signals for combining at the combining circuit.  Demultiplexing circuits are provided for serially outputting both the control signals and the waveforms thus interpolated.
