Abstract: Abstract of the Disclosure A rotary rock bit is formed from at least two individual segments.  The individual segments are positioned together and aligned in the proper position for the final assembled bit.  The seams between the individual segments are in the form of square-butt type joints and the adjoining segments have surface areas that, are in abutting relationship to each other.  A beam of energy such as an electron beam or a laser beam is directed into the seams.  Relative movement between the beam and segments of the bit causes the beam to traverse the seams and join said individual segments together throughout substantially all of said abutting surface areas.                        -1a-

Abstract: ELECTRONIC MUSICAL INSTRUMENT USING    INTEGRATED CIRCUIT COMPONENTS          Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to an electronic musical instrument of the keyboard type wherein the audio frequency signal information is derived from a multi-frequency generator formed by an electronic oscillator and a plurality of divider circuits, and wherein programmable divider circuits are associated with the various keys of the keyboard to generate associated tone signal information.  The programmable divider circuits are formed on a large scale integrated circuit chip and enable alteration of the numerical divisor so that different tone signals can be obtained from the same electronic circuitry thereby enabling the same type of LSI chip to be used for many different circuit configurations.  The LSI chip also provides a scanning circuit that scans an X-Y matrix switching arrangement to determine which one of a plurality of key switches is closed.  The inte-grated circuit unit has a plurality of such programmable divisors arranged to be operated from the same frequency, preferably there being four programmable divisors to obtain a multitude of output audio signal frequencies.  Actuation of a key switch, chord button switch, or foot pedal will enable gate circuit components to cause a signal transfer from a matrix array to a read-only-memory circuit, which, in turn, enables selected ones of the programmable divisors for devel-oping the desired audio signal frequencies.

Abstract: Abstract of the Disclosure Sub-micron titanium diaboride powder and other hard, refractory metal boride powders, such as zirconium diboride and hafnium diboride powders, are prepared by vapor phase reaction of the corresponding metal halide, e.g., titanium halide, and coron source reactante in the presence of hydrogen in a reaction zone and in the substantial absence of oxygen, either combined or elemental.  In a preferred embodiment, the metal halide, e.g., titanium tetrachioride, and boron source, e.g., boron trichloride, reactants are mixed with a hot stream of hydrogen produced by heating hydrogen in a plasms heater.  The reaction zone is mainitained at metal boride forming temperature and submicron soild metal boride powder is removed promptly from the reactor and permitted to cool.  The preponderant number of metal boride particles comprising the powder product have a particle size in the range of between 00.5 and 0.07 microns.  By adding a source of carbon in the reaction zone, a metal boride powder product is prepared containing a minor concentration of carbon, e.g., from above 0.1 about 5 percent by weight total carbon, probably as submicron refactory metal carbide.  Alternatively, submicron metal carbide powders, e.g., titanium, zirconium, halnium or bores carbide powders, or finely-divided carbon can be blended physically with the sub-micron metal boride powder to provided metal borides containing a minor concentration of carbon in the amounts previouly indicated.  Titanium diboride powder compositions containing minor amounts of carbon can be hot pressed, or cold pressed and sintered to densities of at least 95 percent of theoretical.

Title: Power contribution measurement system for internal combustion engines
Inventor: FASTAIA ANTHONY J
IPC: G01M15/04
Filed: 1976-02-27
Granted: 1980-02-19
Abstract: ABSTRACT OF THE DISCLOSURE    The rpm, dwell and timing of an internal combustion engine are measured by starting and stopping a digital counter on the leading edge of pulse waveforms generated either within the engine or by a timing light.  To measure rpm and dwell only the low coil signal is used.  For rpm measurement, the counter is started when the ignition points open, and stopped upon the next opening of the points.  To measure dwell the counter is started by the opening of the points and stopped when the points close, the resultant count being the inverse of dwell, and this count is subtracted from the rpm count to obtain dwell.          Timing is measured by starting the counter upon the firing of the number one cylinder, and providing an additional signal delayed in time as a function of the distributor advance to stop the counter.  The count in the counter is converted to rpm, dwell or timing by either analog or digital techniques.  A high energy ignition adapter cir-cuit prevents triggering of the counter by a false indica-tion of the opening of the points due to a waveform peculiar to low coil signals produced in vehicles using high energy ignition systems.  A timing light delay cir-cuit having a variable delay is incorporated with the timing light to produce the delayed signal proportional to distributor advance, the delay being adjustable within two selectable ranges.  By measuring and displaying the computed dwell for each cylinder in sequence, distributor mechanical wear associated with shaft bearings and drive gears may be detected.  Power contribution and dynamic relative compression for each cylinder may be measured by using the counter to measure the time that the points are open, and the time that the points are closed, for each cylinder in sequence, and displaying the measurements.

Abstract: ABSTRACT OF THE DISCLOSURE          A safety arrangement for a gasoline dispensing station equipped with a vapor recovery system.  Gasoline vapors displaced from a motor vehicle fuel tank during filling are collected through the dispensing nozzle, and are directed first through a flexible hose attached to the nozzle and then through a pipe to an underground storage system.  A preferred embodiment of a break-away valve is placed in the pipe near where it enters the ground such that in the event of an accident, as by an automobile running over the gasoline dispensing console, the break-away valve will automatically close to shut off the vapor recovery system.  This minimizes the danger of an explosion or fire possibly caused by an open vapor recovery system.

Abstract: FOUR-WIRE INTEGRABLE HYBRID     Abstract of the Disclosure A time-sampled port circuit is shown in which the charges impressed by the telephone set on the shunt capacitor of a low-pass filter associated with the port are passively sampled for transmission to the other port circuits, but which capacitor is impulse driven at a repetition rate equal to twice the cut off frequency of the filter with speech samples received from the other port circuits.  By employing passive sampling in the transmitting leg instead of actual charge transfer, as in conventional resonant transfer design, the series inductor normally required in resonant transfer circuits may be omitted with the result that the port circuit switches may be integrated on one chip together with the digital circuitry for encoding and decoding the amplitude samples.          Further, all need for amplifier gain adjustment in the port circuit is eliminated by applying different amplitude send and receive ramp signals to the encoder and decoder circuits.  Transmission delay in a time division system employing the port circuit is compensated by delaying the onset of the receive ramp waveform.

Abstract: A PROCESS FOR DEVELOPING ELECTROGRAPHIC IMAGES BY CAUSING ELECTRICAL BREAKDOWN IN THE DEVELOPER     Abstract Development of electrostatic charge patterns (e.g., electrostatic latent images) carried on a support is accomplished in an electrographic process in which during development, an electrical field which is greater than the electrical breakdown value of the developer (i.e., greater than the maximum electrical field that the developer can support without undergoing electrical breakdown) is established across the developer in the development area.  The process enables development of high quality, large solid-area images-at-high processing rates.
