Title: Interface circuit for low power drain microprocessor-based thermostat
Inventor: ADAMS JOHN T
IPC: F23N5/20
Filed: 1992-09-23
Granted: 2003-12-30
Abstract: A microprocessor-based power switching circuit responds to a common form of noise by disconnecting power from the controlled apparatus. The microprocessor provides an alternating voltage when power is to be provided, and the alternating voltage is converted by a detector circuit to a voltage close to ground which cuts off a transistor. When the transistor is cut off, an interface circuit places a thyristor which performs the actual power switching, into conduction. Noise on the base of the transistor can only drive it into conduction which then puts the thyristor into non-conduction.

Abstract: A biomass fuel gasification chamber, blast tube, and heat exchange chamber are interconnected horizontally and subjected to negative drawing pressure by a large variable speed chimney fan. An auger with an air lock feeds biomass fuel automatically into the gasification chamber. Fuel is moved across the gasification chamber on a partially serrated sloping grate. Three stages of fuel activity are created: anaerobic heating for pyrolysis, combustion, and incandescent charcoal oxydation for gasification. A variable speed fan, variable flue, and directional air duct and baffles control the stages with underfire air. A programmed auger in an airtight chamber removes ash automatically. In large systems a hydraulic moving wedge floor assists the fuel feeding auger and a moving sloping grate moves the fuel. A fan and long preheating duct with baffles and fins inside the gasification chamber preheat and direct air into a blast tube leading from the gasification chamber. Openings from the preheating tube angled both longitudinally and transversely into the blast tube create turbulence in the blast tube directed away from the gasification chamber. Preheated directed air flow and the negative pressure of the chimney fan draw gases from the gasification chamber into the blast tube, crack the gases, and shoot a fire blast into the heat exchange chamber. The fire blast heats an external system. Particulates are removed producing a clean-emission exhaust gas. Temperature and air quality sensors in the chimney provide feedback signals to various system controls to maintain optimum operating conditions.

Abstract: A quick-release connecting apparatus for detachably interconnecting two objects includes male and female members, respectively attachable to the objects. The female member has a generally U-shaped receptacle formed therein which opens at a peripheral edge thereof, and an aperture formed in the front surface of the female member which is aligned with but smaller than the receptacle and communicates therewith. The male member has a stud projecting therefrom with a part-circular head at its distal end which is too large to pass through the aperture but is dimensioned to be received in the receptacle from its open end with the stud disposed through the aperture and is rotatable about the axis of the stud while disposed in the receptacle.      In one embodiment, a spring-biased pawl is mounted on the female member for movement between a locking position projecting into the entrance of the receptacle and a release position out of the entrance. The stud head moves the pawl out of the way upon insertion into the receptacle to permit insertion in any orientation, but the pawl prevents removal of the head from the receptacle except when it is in a single orientation wherein the straight side faces the pawl.      Both reciprocating and pivoting pawls are disclosed.      In another embodiment, a retaining prong is unitary with the female structure and is flexibly and resiliently movable between locking and release positions, while a bias finger integral with the female structure resiliently engages the head to inhibit rotation thereof while in the receptacle.

Abstract: A remotely positionable device  for use  in magnetic resonance imaging includes a magnet which is juxtaposable against the object to be imaged without actually surrounding the object.   When so positioned,  the magnet generates a static nonhomogeneous magnetic field having a determinable measurement  surface  wherein both  the  magnitude  and  the gradient   of   the   field   are   substantially   constant.          Additionally,  the  device  includes  an  RF  antenna  for periodically pulsing nuclei in the measurement surface with pulses of the Larmor frequency to initially tilt the nuclei and to subsequently refocus the nuclei.   The device also includes a pair of gradient coils which generate a gradient fields that are superposed on the static field to encode the nuclei.  The RF antenna subsequently receives a plurality of encoded spin echo signals from the refocussed nuclei which are averaged by a computer to create a measured response.          Specifically, the nuclei are refocussed and the encoded spin echo signals are received at a rate that is proportional to the gradient of the static flux field.  The computer is also used  to  create  an  image  from  a  plurality  of  measured responses taken from differently encoded spin echo signals.

Abstract: The present invention makes it possible to obtain good characteristics of forming sprays of fuel jetted through a plurality of injection ports of a fuel injection valve with respect to separation of sprays in different directions, atomization, jetting angles and penetrating force.      Fuel jetted through the injection ports of the fuel injection valve is jetted in separate jets from a plurality of fuel flow separating holes of a sleeve nozzle. On the other hand, band-like assist air flows are jetted in a two-dimensional manner from slit-like air holes opened on the opposite sides of the fuel flow separating holes to impinge obliquely against the jetted fuel. Atomization of fuel jetted through the plurality of fuel flow separating holes is thereby promoted and fuel sprays are accurately separated and supplied independently in two directions toward two intake valves while the directions of jets from the injection ports of the fuel injection valve are maintained, thus injecting and supplying fuel. As a result, an amount of fuel impinging directly against walls which separates and forms two intake ports is reduced and an amount of atomized sprayed fuel directly entering a combustion chamber from the intake ports is therefore increased, thereby improving combustion characteristics.

Abstract: A spoon lure for fishing in fresh water or sea water, comprised of a wedge-shaped strip of highly reflective metal or any other suitable material that is bent to a radius along its length and width, with a rudder at the wide end of the wedge set at an angle to the length of the body and rolled in the opposite direction of the radius.  At the narrow end of the wedge, or the leading edge, there is a hole for fastening a swivel device which in turn is fastened to a fishing line.  At the wide end, or trailing edge, there are two holes for fastening a hook.  One hole is on center of the wide end at the base of the rolled wing and one hole is on the corner opposite the rolled rudder.  This configuration results in a lure that will spin through the water with a tight pattern when the hook is placed in the center hole.  When the hook is moved to the corner hole, the action changes to a slower spin with a random dodging or darting motion, resulting in a much wider pattern.  In addition to two different actions when the lure is being drawn through the water, a third aggressive action is evident when the lure is used in a jigging or flipping presentation.
