Abstract: ABSTRACT OF THE INVENTION       In a Global Positioning System type of navigation system, a biphase modulated radio frequency input signal is applied to the "front end" of a double heterodyne receiver having a second intermediate frequency stage which operates in the audio frequency range.  The audio output signal is phase locked to a 1 KHz reference signal and is applied to a microprocessor for processing via an interface circuit which includes a relatively simple amplitude detector and a novel biphase detector.  The microprocessor also controls the phase shifting of a pseudorandom noise code generator whose output is modulated with the output of the first intermediate frequency stage of the receiver.

Abstract: ABSTRACT OF THE DISCLOSURE   A wide range radioactive gas concentration detector and monitor which is capable of measuring radioactive gas concentrations over a range of eight orders of magnitude. The device of the present invention is designed to have an ionization chamber which is sufficiently small to give a fast response time for measuring radioactive gases but sufficiently large to provide accurate readings at low concentration levels.  Closely spaced parallel plate grids provide a uniform electric field in the active region to improve the accuracy of measurements and reduce ion migra-tion time so as to virtually eliminate errors due to ion recombination.  The parallel plate grids are fabricated with a minimal surface area to reduce the effects of con-tamination resulting from absorption of contaminating materials on the surface of the grids.  Additionally, the ionization chamber wall is spaced a sufficient distance from the active region of the ionization chamber to mini-mize contamination effects.

Abstract: ABSTRACT:             A method and system that discourages the use of unauthorized program software with proprietory data processing system hardware.  Under the control of a start command signal generated by the central processing unit of the system an identifier is fetched up from a specified location in a program memory which is physi-cally separable from the data processing system.  The identifier is then compared with a reference identifier which is stored in the proprietory hardware.  The hard-ware blocks further execution of programs contained in the program memory if the identifiers are not congruent. In a preferred embodiment the identifier is displayed and the display is material which can only be legally used with the permission of the manufacturer or proprietory of the hardware; for example a registered trademark or copyrighted material.

Abstract: ABSTRACT OF THE DISCLOSURE   A pumping unit for wells which is hydraulically powered and adapted to replace or used in lieu of conventional pump jacks.  The hydraulic system utilized with the hydraulically operated pumping unit includes an accumulator system which stores energy produced by gravity induced downward movement of the pump rod and other pump components during the down stroke and automatical-ly utilizes this stored energy to assist in lifting the pump components and the column of production fluid thereby increasing the efficiency of the pumping unit.  The pumping unit utilizes a pair of hydraulically operated piston and cylinder assemblies having a lower end stationarily connected to a supporting structure and an upper end connected to a vertically guided slide assembly having a pair of grooved pulleys journaled thereon with flexible link chains entrained thereover with one end of the chains being anchored to the supporting structure and the other ends depending from the slide and connected to the polish rod whereby the linear movement of the pistons in the piston and cylinder assemblies will be one-half of the linear movement of the polish rod, thereby providing a compact structure so that the vertical movement of the slide can be more effectively guided and controlled.  The entire pumping unit is mounted on a supporting skid or framework with all of the valves and high pressure connections being disposed interiorly of a reservoir except for the motor-pump unit and the cylinders and conduits connecting the upper and lower ends of the cylinders to the hydraulic system.

The device includes first and second parts which are movable with respect to each other.  The second part, which is disposed on and extends outwardly from the first part, is movable between an attracted position in which it is extended to a predetermined extent, and a retracted position in which it is extended to a lesser extent.  Magnets and springs hold the two parts in the attracted position with a predetermined force which is easily overcome if the parient touches the second part of the device.  After initial separation, increasing force is required to further compress the springs and cause further movement of the second part.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for converting spectral and light intensity values directly to digital data, utilizes an image sensor having at least one row of sensor elements, each element including a light sensitive capacitor and an access switch and which changes state and produces a corresponding digital output signal when a predetermined charge threshold is exceeded by the capacitor whose charge is a function of light intensity of an illuminating light source.  The image sensor is illuminated with a reference light source having a known intensity through a neutral density gradient filter and the digital output of the sensor is examined for the row to obtain digital data corresponding to the number of state changes in the row.     The image sensor is then illuminated with an unknown light source through the filter and the digital output of the sensor for the row is examined to obtain digital data corresponding to the number of state changes in the row.          The intensity of the unknown light source is determined in digital form for the row as a function of the digital data and the known intensity of the reference light source.
