Abstract: ABSTRACT           The invention relates to a method for the recognition of characters, in which in a learning and in a working phase the properties of the signals are classified within a number of groups and their frequencies of occurence are statistically recorded in the form of logarithmic values, which are added up so as to give the product--probability and to allow a decision to be made by comparison with regard to the character read.   A device for carrying out this method comprises a character pattern manipulator the output of which is connected to a number of circuits for simultaneous detection and classification of the various properties.

Abstract: ABSTRACT OF THE INVENTION         A lithospheric electromagnetic telemetry system specifically adapted for telemetry of oil well drilling parameters from well bottom to surface of the earth.  Sensors measure such parameters as pressure, temperature, salinity, direction of well bore, bit conditions, as well as the standard well logging parameters.  The sensor outputs are converted to digital form and stored in a local memory until they are transmitted upon a triggering signal from a surface station.  Transmision is accomplished by phase shift modulating an ELF (Extra Low Frequency) or ULF (Ultra Low Frequency) carrier, preferably in the range of 1-30 Hz.  Repeater stations which delay and retransmit the signal are spaced along the oil well drill pipe as required.  Both the well bottom station and repeaters are mounted inside the oil well drill pipe without substantially decreasing clearance for mud flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel electrolytic cell performs an electrolysis process at improved efficiencies by generating short wave electromagnetic radiation which irradiates the electrolyte to decompose the electrolyte by radiolysis.  Thus the process is one of electrolysis combined with radiolysis.  In one embodiment pulses of high voltage electrical energy are applied between the anode and cathode of the cell to generate both the radiation for radiolysis and a pulsed DC current in the electrolyte for electrolysis.  In a second embodiment the pulses of high voltage electrical energy are discharged between radiation generator electrodes disposed beneath the electrolyte chamber.  In both embodiments a generally cylindri-cal anode with a fluted outer surface is surrounded by a segmented cathode having an active area equal to the active area of the anode.  An electrolyte, which may be a 25 percent solution of potassium hydroxide is introduced into the cell for production of hydrogen and oxygen at the cathode and anode respectively.  This high voltage pulses are derived from a DC supply by pulse generating circuitry and a transformer located within an oil filled chamber inside the anode.  The transformer generates a magnetic field in the electrolyte which provides preferred paths for the high speed electrons of the short wave electromagnetic radiation and also for the ions in the electro-lyte thereby increasing the possibility for collision between the electrons and ions with subsequent improved radiolysis yield.

The method includes the steps of forming a table, polishing an off number of faces on a base, which faces converge to a point and forming a plurality of facets on the girdle of the stone between the base and the table whereby the inclination of the faces with respect to the table is such that light entering the table substantially normal thereto is internally reflected to the opposite corner where it is subsequently internally reflected back to the face of initial incidence and out of the upper part of the stone to impart brilliance thereto.  The gemstone is characterised by having a tuble portion defined by a table and a girdle having a periphery greater than the periphery of the table to define a pyramidal table portion and a base defined by a plurality of faces converging towards a point on the side of the gridle opposite the table portion which stone has an odd number of sides, the inclination of the faces to the plane of the table permitting light entering the table substantially normal thereto to be internally reflected at an opposite corner for subsequent internal reflection at the face of initial incidence and out of the upper part of the stone to impart brilliance thereto. Gemstones in accordance with aspects of the present invention particularly include maccle diamonds which are capable of being cut in accordance with the method of an aspect of this invention to produce gemstones having improved brilliance with a reduced amount of waste from the uncut stone.

Abstract: ABSTRACT                         An impact tool is described which is capable of developing percussive forces for rock drillings, pile driving, seismic exploration and other repetitive high force applications.  The tool contains a hammer and a valve which may be hydraulically actuated so as to oscillate; repetitively executing forward and return strokes during each cycle of oscillation.  The valve is actuated in the forward stroke direction by being engaged by the hammer, and in the return stroke direction by fluid pressure means so as to switch the pressure in a cavity in which both the valve and the hammer are disposed for developing forces on the hammer so as to sustain its oscillation.  A fluid filled pocket is provided into which the valve enters as it moves in the forward stroke direction, after having switched the pressure in the cavity.  A passage is provided on the hammer through which the fluid trapped in the pocket can flow to an outlet channel or to the cavity, depending upon the position of the hammer.  A control valve in the channel determines the flow therethrough, and thus the dispiscement of the valve into the pocket, thereby providing control over the stroke of the valve and the period between switching of the pressure in the cavity.  The hammer stroke length and the frequency and energy of the impacts delivered  by the hammer are dependent upon the switching period, and may be varied by the use of the control valve.

Abstract: ABSTRACT     The noisy amplified signal from a photoelectric device is passed through an electronic low-pass filter before having its direct current component read on a meter.  The cut-off frequency of the low-pass filter is adjusted in known manner by rotation of a control knob, so as to suitably match the cut-off frequency to the noisiness of the signal with a view towards speeding up the stabilization of the meter reading.  To overcome the slugish-ness of the  system, the same control knob is briefly pushed, thereby overriding the low pass control.  The method of using the system to speed up meter reading is described.

Abstract: AUTOMATIC HEADING SYNCHRONIZATION CONTROL            Abstract of the Disclosure:     The automatic heading retention mode of operation of a flight control system for a rotary wing aircraft is discontinued and reestablished through the use of logic circuitry responsive to the bank angle of the aircraft and to the force applied to a control stick by the pilot.  When the bank angle of the aircraft exceeds a preselected minimum and the lateral force applied to the cyclic pitch stick also exceeds a predetermined minimum the logic circuit operates to isolate the heading hold control from heading error signals and the heading retention mode of operation is automatically resumed when both of the bank angle and stick force fall below the preselected minimum levels.  The invention may also encompass the application to the control mechanism of signals which will cause the aircraft to perform coordinated turns above a preselected minimum airspeed.

The apparatus includes an optical cavity containing a vapor cell and pumping means including at least one optical pumping source for directing energy at the cavity.  In one embodiment the cavity en-closes a material capable of stimulated emission in response to said pumping.  The material has at least three atomic energy level with at least a first and second atomic energy level separated by a particular energy quantum approximately equal to 628 cm-1; a transition from said first to said second atomic energy level favored over all other possible transitions from said first atomic energy level; said third atomic energy level, from which atoms can be pumped to said fist atomic energy level in response to said pumping means.  While this is consistent with classical laser operation the apparatus disclosed herein can also be used for stimulated Raman scattering.  Tunability is achieved by tuning the pumping sources in the case of stimulated Raman scattering, or with the aid of the Zeeman or Stark effects for classical laser operation.  Typical materials are potassium or strontium vapors.  Several pumping arrangements are also disclosed.
