  • Patent number: 4930446
    Abstract: The present invention comprises a method for cyclically controlling a poultry barn environment. It coordinates stimulation such as illumination, ventilation, sprinkling and temperature. At the commencement of the cycle, the lights are turned off, the ventilation is reduced to a normal rate and heaters are turned on to provide an optimum environment for the poultry's inactive phase. During the dark, inactive phase, a massive purge is implemented to reduce ambient dust. At the end of the dark phase, the lights are turned on, sprinklers are turned on and the temperature in the barn is reduced. The lights stimulate activity by the fowl. The sprinkling removes still more dust from the air.The reduction in temperature stimulates feeding. At the end of the illuminated, active phase, the lights are turned out and the cycle is repeated. By coordinating the stimulation, a healthier fowl and greater growth rate are thereby produced.

  • Patent number: 4930451
    Abstract: A device for the controlled, sustained-release of an animal-treating composition, such as an insecticide, onto the surface of an animal in contact with the device comprises a reservoir defined by a permeable, imperforate, polymeric membrane. A porous packing inside the reservoir continuously wets the inside of the reservoir with the animal-treating composition so that the composition can continuously permeate through the membrane to the outer surface of the reservoir. A porous sheath in contact with the outer surface of the reservoir continuously conducts the composition away from the membrane and continuously deposits the composition onto the surface of the animal. The device is particularly useful for controlling horn flies on range animals, such as cattle.

  • Patent number: 4930454
    Abstract: Disclosed is a catalytic combustor and systems for the boilerless stoichiometric production of a working fluid such as steam from a fuel-mixture comprised of a carbonaceous fuel and a diluent such as water mixed in a thermally self-extinguishing mass ratio. Production of the steam is by a controlled substantially stoichiometric process utilizing a combustor to provide steam over a wide range of heat release rates, temperatures and pressures for steam flooding an oil bearing formation. Even though formation characteristics change during a steam flooding operation, output steam of the combustor may be kept at a constant heat release rate by dividing the total amount of water passing through combustor between a first portion which is included in the fuel-mixture and a second portion which is injected into the heated products of combustion.

  • Patent number: 4930455
    Abstract: A motorized water valve of the butterfly-type having the motor case and gear reduction housing formed integrally with the valving chamber. The metal butterfly has elastomeric material formed thereover to provide improved sealing and prevent leakage when the valve is closed thereby enabling substantially shortened warm-up in thermostat application. The control system employs the valve at the engine block outlet to control coolant flow to the radiator in response to an electrical control signal based upon comparison of the sensed block temperature with a desired engine temperature. The control system also employs the valve to control coolant flow to the heater core in response to an electrical control signal based upon a comparison of sensed in-car temperature and a desired in-car temperature selectd by the driver. Heater core discharge air may also be sensed and included in the comparison to provide a control signal to permit automatic in-car temperature regulation.

  • Patent number: 4930465
    Abstract: A system for accomplishing solenoid control of engine valves places a soldnoid valve between an oil gallery and the lost-motion actuator for each valve. Although the basic phasing for the valves is established by a camshaft, the actual phasing is accomplished by causing the valve actuators to execute lost-motion. The amount of lost-motion establishes the actual opening and closing phase angles for the valves. The amount of lost-motion of each actuator is established by the timing of the opening and closing of the corresponding solenoid valve. Oil that is pumped from the actuators can be stored in an accumulator that is connected to the gallery for subsequent use in replenishing the actuators.

  • Patent number: 4930474
    Abstract: The invention relates to a distribution and control valve in a fuel injection engine pump especially for a large multi-cylinder diesel engine, in which the fuel is injected into the cylinder by mdans of two or more injection valves (A;B). The pump includes a pump cylinder (1) and, inside thereof in a pump chamber (2), a reciprocatingly movable piston member (4), which is arranged through its movement to feed fuel via distribution ducts to the injection valves of the cylinder in question. The pump cylinder (1) is provided with an extra chamber (11) connected to the pump chamber (2), to which extra chamber there is tightly adapted a long-shaped valve member (12) following the movements of the piston member in the axial direction thereof, and inside the valve member (12) there is a fuel duct (13) connected to the pump chamber (2). The feed ducts (16;5a,5b) of the separate valves are connected to the extra chamber (11) in the axial direction of the valve member (12) to different points distant from each other.

  • Patent number: 4930475
    Abstract: A rotational speed control system for an engine includes controls for determining whether the throttle is closed beyond a predetermined position, whether the engine is mechanically loaded, and whether the engine rotational speed exceeds a predetermined speed. A control delays the ignition timing of the engine when the throttle is closed beyond the predetermined position, the engine is not mechanically loaded, and the rotational speed exceeds the predetermined speed.

  • Patent number: 4930477
    Abstract: A system and method for controlling an ignition timing for an internal combustion engine mounted in a vehicle are disclosed in which a limit value for the ignition timing value is provided so that a difference between a current ignition timing and a previous ignition timing is within the limit value and the limit value is set according to a magnitude of an engine acceleration. For example, when an abrupt engine acceleration occurs, the limit value is set to 15 degrees. When the engine is in a steady state (no abrupt acceleration from an idling condition), the limit value is set to four degrees. Therefore, no vehicle body shock occurs due to the abrupt change in an engine output torque caused by the abrupt change in the ignition timing and a response characteristic of a rise in the engine output torque during the abrupt acceleration can be assured.

  • Patent number: 4930479
    Abstract: An irregular combustion determining device comprising a variation detecting unit, a first determining unit, and a second determining unit. The variation detecting unit detects a variation in an engine speed on the basis of two successive engine speed detected at predetermined crank angles. The first determining unit determines that an irregular combustion has occurred when the variation in the engine speed detected by the variation detecting unit is larger than a predetermined first variation in the engine speed. When the first determining unit determines that an irregular combustion has occurred, at the next detection of the variation in the engine speed by the variation detecting unit, the second determining unit determines that an irregular combustion has occurred when the variation in the engine speed detected by the variation detecting unit is larger than the predetermined second variation in the engine speed which is smaller than the predetermined first variation in the engine speed.

  • Patent number: 4930482
    Abstract: An engine control apparatus for controlling fuel injection on the basis of a pressure value relating to the intake pipe pressure of an engine. All variations in the engine load are monitored and a detection signal is output when any variation is equal to or larger than a predetermined value. A timer is operable for a predetermined time in response to such detection signals. Fuel injection is controlled in response to the pressure value during the period when the timer is operative and in response to a value obtained by performing low-pass filter processing of the pressure value during the period when the timer is inoperative.
