Abstract: FINGER IDENTIFICATION               Abstract of the Disclosure A finger pressed against a platen provides a finger-print object which is scanned by an interrogating beam of col-limated light in the form of a slit and that is linearly displaced across the platen.  As the slit-beam scans across the back surface of the platen, the reflected light beam is modu-lated.  The modulated beam is imaged onto a linear array of photodiodes to provide a series of output signals indicative of modulation information.  The outputs of the diodes are serially interrogated at each of successive scan positions to provide a set of signals containing fingerprint information.  The platen has a transparent glass base.  A layer of transparent, compres-sible, resilient epoxy is on the back of the glass base.  The epoxy layer has a flat back surface.  A thin silver reflecting layer on the back surface of the epoxy provides a flat mirrored surface to reflect the light beam.  A further epoxy layer on top of the silver provides mechanical filtering.  A lacquer layer at the back protects the platen from wear.  When a finger is applied to the back surface, the ridges of the finger distort the underlying layers sufficiently so that the reflected light at the ridge zones is scattered while the reflected light at the valley zones is collimated.  This difference in scatter is transformed by an imaging lens to a difference in intensity at the diode array.     -i-

Abstract: The variable speed transmission includes a power input drive shaft and a variable throw crank having a zero throw position aligned with the input shaft.  The variable throw crank is coupled to the input shaft for rotation therewith and its eccentricity with respect to the axis of rotation of the input shaft can be varied.  A control plate, also referred to as a master link, is rotatably mounted on the crank and a plurality of clutches having input and out-put shafts are operatively connected to the control plate through a plurality of pitman type links, whereby the control plate oscillates the input shafts of the clutches upon rotation of the power input shaft and variable throw crank of the transmission.  The outputs of the clutches are connected to an output shaft for the transmission.  By varying the throw of the variable throw crank the ratio between the rotary speed of the output shaft can be infinitely adjusted from zero to a maximum ratio determined by the maximum eccentricity of the variable throw crank with respect to the axis of rotation of the input shaft.  A preferred embodiment is to revert the above.

Abstract: COLUMN FORMATTING BY TYPED EXAMPLE                     Abstract The technical advance solved by the method of the invention is the formatting of a table of columns and gutters by way of typed example in both the creation of new formats and the revision of the old.  In this regard, the operator keys in text characters defining the maximum column width and tab stops for the column, and spaces over to the next column and repeats this for each of the columns in a newly created format.          This single entry permits the column and gutter widths to be automatically aligned with tab stops.  This formatted column example line is then vector encoded and saved by the system.  If it is subsequently desired to revise a saved table, its encoded format line is recalled, rebuilt, and then revised by enter-ing additional text and control characters defining an altered width or tab stop settings of an existing column or a new column.  This revised column example line is then encoded and saved.  The encoding is a memory conservation feature by saving a compacted parameter set of formats.  There is also provided an automatic one-character wide gutter insertion when creating a new column to prevent the operator from failing to include a gutter after having formatted adjacent columns.

Abstract: METHOD AND APPARATUS FOR DETERMINING    THE DENSIDENSITYY CHARACTERISTICS OF UNDERGROUND EARTH FORMATIONS  Abstract A plurality of detectors (12) is disposed within a bore hole (14) for ascertaining the frequency and trajectory of high-energy muons that penetrate through the earth. This information is converted by data processor (42) into an integrated density value of the earth for incremental angular lines of sight extending through spaced-apart elevations along the detectors (12). The data processor (42) uses a tomographic analysis process to combine together all of those integrated density values for all of the elevations of interest to calculate the densities of discrete spatial volumes composing the underground region being investigated. Detectors (12) produce electrical signals indicative of the trajectory of the passing muon. The signals are recorded by time-to-digital convertor ("TDC") units (30). If the signals appear to have possibly originated from a high-energy muon, a microprocessor (38) retrieves the information collected by TDC units (30) and transmits it to a data logger (40) located at the earth's surface. The data processor (42) then utilizes tomographic analysis to make the localized density determinations discussed above.
