Abstract: HALL EFFECT ELECTRONIC IGNITION CONTROLLER WITH PROGRAMMED DWELL AND AUTOMATIC SHUT-DOWN TIMER CIRCUITS     Abstract An electronic ignition controller operable from a Hall Effect pickup Device in a ballast-resistorless, indutive-type ignition system for an automotive vehicle internal combustion engine and featuring programmed dwell and automatic shut-down timer circuits, which control current dissipation in the ignition coil.  The programmed dwell timer circuit enables energization of the ignition coil for a controlled or substantially constant period of time over substantially the entire range of engine operating speeds up to a predetermined high engine speed above which the ignition system reverts to a constant duty cycle char-acteristic determined by the character of the triggering input or pickup device.  The automatic shut-down timer circuit operates to block the energization of the ignition coil if the controller remains in a state of conduction that maintains the ignition coil energized for a predetermined prolonged period of time that is greater than the actual dwell period or ON time of the coil at low engine or cranking speeds.

Abstract: Abstract of the Disclosure Characters are projected from a spinning disc on a carriage which moves relative to the stationary film to space characters on the film.  A lens holder with a plurality of lenses of different magnifications normally is locked to the carriage and moves with the disc during character spacing motion, but can be selectively unlocked and moved relative to the disc in order to change from one character row to another, or bring a different lens into use, thus easily changing the style and/or size of characters.  In this disclosure, a pi-character matrix bearing auxiliary characters and/or symbols is attached to the carriage, at a location beyond the disc but near the travel path of the lens holder.  In projecting images from the pi-character matrix, the lens holder is moved relative to the carriage until the selected pi-character or symbol is aligned with the desired lens.  An auxiliary lamp then is energized to illuminate the character or symbol.  Preferably, the symbols include slots for use in making horizontal and vertical lines or "rules". The lamp is energized continuously and either the character spacing mechanism or the line spacing mechanism is operated while the lamp is lighted, thus forming continuous lines on the film.  The use of a turret as a lens holder is described. The turret is rotatable to change styles and/or sizes by bringing a new lens into operative position.  The turret is rotated by a selective drive coupling which uses the motion produced by the character spacing mech-anism to rotate the turret.

Abstract: SEPARATION OF LIQUID HYDROCARBONS FROM NATURAL GAS               Abstract of the Disclosure Ethane and other hydrocarbons of higher boiling point are separated as a liquid from natural gas to leave a gas con-sisting principally of methane for delivery to a pipeline.  The natural gas is passed in countercurrent heat exchange with the liquid product and with the pipeline gas to cool the natural gas to a temperature at which a major part of the ethane is condensed.  The condensed ethane and higher boiling point hydro-carbons are separated from uncondensed vapors in the natural gas and the vapors are expanded to a low pressure and delivered into the upper end of a fractionating tower.  The condensate is expanded to the same pressure and introduced into the frac-tionating tower at a midpoint thereof.  Gases discharged overhead from the fractionating tower constitute the pipeline gas that is returned to the heat exchanger for countercurrent heat exchange with the natural gas.  The liquid hydrocarbons withdrawn from the lower end of the fractionating tower are returned to the heat exchanger for heat exchange with the natural gas to cool the natural gas and to supply heat to vaporize a portion of such liquid products which are returned to the fractionating tower.          That part of the liquid product that is not returned to the fractionating tower is compressed, cooled and delivered from the system.

Abstract: ABSTRACT OF THE DISCLOSURE A wood splitter, particularly suited to hydraulic operation, for mechanically splitting sections of wood lengthwise for shakes or for more suitable sizes for burning is provided. In a preferred form the device is mounted on a trailer having a flat working deck. A column, which is lowerable for travel, projects upward out of the deck. A leverl arm actuated by a hydraulic cylinder is attached to the column below the deck and upon actuation of the cylinder projects upward through a hole in the deck. A splitting blade is slidably mounted on the column over the lever arm. A piece of wood is placed over the lever arm and the blade which is also actuated by a hydraulic cylinder is lowered, by operation of a foot lever, against the top of the piece of wood. The contact with the wood is sensed by a sequence valve which then causes the lever arm to raise above the deck forcing the wood to be split by the blade. If the wood does not split cleanly the blade automatically lowers more closely toward the lever which retracts then actuates again. Another embodiment of the wood splitter utilizes the blade mounted on a threaded screw. The screw is rotated to raise or lower the blade rather than a cylinder.

Abstract: CIRCUIT BREAKER APPARATUS INCLUDING     ASYMMETRICAL FAULT DETECTOR     ABSTRACT OF THE DISCLOSURE         A circuit breaker apparatus is taught which in-cludes three time delayed modes of interruption and an instantaneous interruption.  A long time delay mode is taught for interrupting overload current in the line to be protected.  The latter time delay is inversely proportional to the square of the overload current.  A short time delay mode is taught for providing a circuit breaker tripping operation after a predetermined fixed time delay when the current flowing in the line to be protected exceeds a predetermined amount.  An asymmetrical fault detecting range of interruption is taught which overlaps the region of overload current which normally would require an instan-taneous tripping of the circuit breaker as a function of the properties of the circuit breaker but which nevertheless delays interruption of the circuit breaker for a relatively short period of time to test subsequent peaks of the fault or overload current to determine if the latter current decays to a value which does not necessitate quick tripping of the circuit breaker during the delay period.  The latter case is related to the occurrence of a fully offset asym-metrical transient fault condition.

Title: Spray marking assembly
Inventor: POFFENROTH ALFRED E
IPC: A01B69/02
Filed: 1977-09-28
Granted: 1981-01-06
Abstract: ABSTRACT OF THE DISCLOSURE           The spray marking assembly is mounted on an agri-cultural or horticultural spraying or spreading implement to show visually, the area traversed so that the overlap or skip may be avoided.  Usually, a pump sprays a dye from a tank through hoses to the extremity of the spray boom.  This often causes poor markings due to scatter and loss as the pump has to move the fluid through the relatively long lines when demanded and the fluid and/or pressure tends to leak from the lines when not marking.  The present device uses a motor and pump which run all the time when in use thus main-taining a constant pressure of fluid in the lines.  A sole-noid valve is situated at the extremity of the lines adjacent the discharge nozzle so that as soon as the valve is opened, the fluid under pressure is available at the nozzle.  An ac-cumulator is also provided adjacent the solenoid valve to give the necessary storage of extra fluid for dispersal through the discharge nozzle and to maintain the necessary pressure during opening of the discharge nozzle.  A solid state timer in the cab of the tractor permits the operator to select the duration of spraying of the marking fluid, and the frequency of marking.  An over-ride control enables the operator to mark manually on corners, knolls, and the like independently of the automatic actuation of the solenoid valve.
