    摘要: A gas sensor for being placed into a gas stream such that the gas sensor is insensitive to any specific rotational orientation about a longitudinal axis of the sensor within the gas stream. The sensor includes 1) a base having an axis that is perpendicular to the gas stream, 2) a sensor element on the base, 3) a catalyzed sensor element on the base proximate the sensor element, for creating an exothermic reaction upon contacting the gas stream thereby forming a heated gas stream portion, and 4) the catalyzed sensor element and the sensor element are positioned on the base with a sufficient axial separation therebetween so that as the base rotates about the axis, the heated gas stream portion will not contact the sensor element. In particular, the base has a second axis being perpendicular to the axis and separating the sensor element from the catalyzed sensor element. Additionally, the invention provides a device that may have both the sensor element and the catalyzed sensor element including a longitudinal axis. Wherein, both the sensor element and the catalyzed sensor element may have many different shapes. Both the sensor element and the catalyzed sensor element may have two or three sides that are coextensive with at least one void. As a result of having a void the base may include a bridge that connects at least one side of the sensor element and the catalyzed sensor element to the base.

    摘要: The temperature of each heating element among a plurality of heating elements is regulated by opening and closing a relay associated with each heating element in response to the monitored temperature of each heating element. The voltage across all of the relays is interrupted simultaneously at predetermined intervals, and each relay is opened or closed only when the voltage is interrupted. This permits the use of relays having lower current ratings and also extends relay life.

    摘要: A printed circuit board holder wherein several boards are securely held in place in a fixture by force exerting devices pushing against the board edges. The fixture includes recessed openings where the boards are located and force exerting devices positioned between pairs of the openings. The force exerting devices include an elliptical member which is mounted flush with the boards and is rotatable to push the two adjacent boards apart from each other. Contact is made only with the board edges to provide a smooth surface across the force exerting means, the circuit boards, and the fixture.

    摘要: A sensor assembly for sensing a movable object which, in one embodiment, includes a housing defining an interior cavity. A rotor is retained in the cavity. The rotor defines a central bore and a magnet is mounted in an off-center pocket defined by the rotor. The rotor is coupled to the shaft of the movable object whose position is to be measured. A sensor is also retained in the cavity in a relationship at least partially overlying the magnet and adapted to sense at least the direction of the magnetic field generated by the magnet to generate an electrical signal indicative of the position of the movable object. In another embodiment, the rotor and sensor are mounted in separate interior housing cavities separated by an interior housing wall.

    摘要: An anti-rotation device or assembly for preventing the rotation of a magnet in a linear position sensor and eliminating the risk of undesired magnetic field measurements and incorrect sensor signal outputs. In one embodiment, the anti-rotation device is an anti-rotation plate which is fixed to the housing of the linear position sensor and a magnet carrier which includes at least one finger extending into a receptacle defined in either the edge or the body of the magnet carrier to prevent the magnet carrier from rotating relative to the plate. In another embodiment, the magnet carrier includes a key and the magnet includes a groove. The key extends into the groove for preventing the rotation of the magnet in the magnet carrier.

    摘要: A simulated brick panel is made by applying a first layer of mortar on a base panel, applying a second layer of mortar over the first mortar layer, and then cutting grooves in the second layer to expose the first layer of mortar to view. The first layer of mortar is chosen to have a color of mortar and the second layer of mortar is chosen to have a color of brick so that the grooves will effect a simulation of mortar lines between bricks. A tool especially adapted for cutting the grooves is also provided.

    摘要: In accordance with the present invention, a non-contacting position sensor using bipolar tapered magnets is provided. A non-contacting position sensor in accordance with the preferred embodiment uses a pole piece having a first plate and a second plate. Four magnets are affixed to the first plate and second plate. Each magnet has a thick end and a thin end. Two magnets generate a linearly varying magnetic field having a first polarity, while the other two magnets generate a linearly varying magnetic filed having a second polarity. An air gap is formed in the space between the four magnets. A magnetic flux sensor is positioned within the air gap. The component whose position is to be monitored is rigidly attached to either the pole piece or the magnetic flux sensor, causing the magnetic flux sensor to move relative to the magnets within the air gap as the component moves. A varying magnetic field is detected by the magnetic flux sensor, resulting in a signal from the magnetic flux sensor that varies according to its position relative to the four magnets. The signal from the magnetic flux sensor is used to provide an indication of the position of the component to be monitored.

    摘要: A combustible gas detector or sensors having a multi-level sensitivity circuitry. The gas detector has a bridge circuit for outputing voltages indicative of gas concentrations contacting the bridge circuit. There is a power supply node electrically coupled to one end of the bridge circuit. There is also a voltage control circuit, coupled between the bridge circuit and the power supply node, for controlling when at least a low and high input voltage level is supplied to the bridge circuit so that the bridge circuit has at least two levels of gas concentration discernability. The bridge circuit outputs distinguishable voltage levels for high gas concentrations in response to receiving the low voltage level. Additionally, the bridge circuit outputs distinguishable voltage levels for low gas concentrations in response to receiving the high voltage level.
