Abstract: A plant curing and drying hanger apparatus for use with harvested plant material which includes a primary frame, a plant support bar and one or more separators arranged to space from one another plant sections positioned on the support bar. The plant support bar is hingedly coupled to the primary frame. A latch releasably joins the plant support bar to one end of the primary frame so that an end of the plant support bar can be dropped away from the primary frame to enable the insertion and removal of plant sections into the spaces between adjacent separators to allow for effective plant drying and efficient loading and unloading of plant material without damaging the product.

Abstract: A pointer-type alarm mark structure of a micro-differential pressure gauge includes a transparent casing. The transparent casing has a shaft thereon. At least one alarm index is provided on the shaft. By adjusting the alarm index to a desired position, the user can know whether the pointer of the gauge is within a safe area.

Abstract: An alarm mark structure of a micro-differential pressure gauge includes a transparent casing. The transparent casing has at least one recess thereon. The recess is located corresponding to the range of movement of a pointer or a scale plate. At least one mark member is provided on the transparent casing. The mark member has an engaging portion. The engaging portion is inserted in the recess, such that the mark member is coupled on the transparent casing. The user can place the mark member on the recess corresponding to the numerical value on the scale plate as desired to know whether the pointer is located within a safe area.

Abstract: A position indicator may include a position indicator display and mechanism. A polymer housing houses the position indicator display and mechanism and a one-piece clear polymer cover encloses the position indicator display and mechanism in the polymer housing. The position indicator may further include a hinge and hand-operated latch that secures the one-piece clear polymer cover to the polymer housing such that the one-piece clear polymer cover can be opened without the use of tools.

Abstract: A position indicator for a motor drive for actuating a step switch, tap changer, or dipping coil, has a display board having front and back faces and a first circular array of symbols on the front face corresponding to individual switching phases traversed during changeover of the motor drive from one operational position into another neighboring operational position. A first shaft extending through the board centrally of the first array and defining a first axis carries a pointer at the front face rotatable about the first axis through positions aligned with the symbols. A second circular array of symbols on the front face is associated with individual possible stationary operational positions of the step switch, the tap changer, or the dipping coil. A second pointer shaft projecting through the board centrally of the second array and defining a second axis carries a second pointer at the front face rotatable about the second axis through positions aligned with the symbols of the second array.

Abstract: The present invention comprises an oil-filled depth gauge which is made far less sensitive to violent shock and the potential resulting inaccuracies to the maximum depth gauge indicator from such shock. More specifically, the present invention comprises an improved oil-filled scuba diving depth gauge in which the improvement provides a fluid dam member which may be affixed to or molded into the transparent enclosure covering the dial face to effectively block the flow of the oil in the region of the gauge occupied by the maximum depth indicator dial. The fluid dam reduces the likelihood that a sudden jar or other violent shock will induce a relative differential in the motion between the oil and the gauge body which might otherwise produce inaccuracies in the position of the maximum depth indicator dial.

Abstract: An aircraft flight dynamics indicator utilize an artificial horizon and a plurality of indicators to establish climb and descent indexes wherein safe flight may be maintained during ascent and descent by cuing aircraft attitude to a visibly perceptive change in aircraft motion related to the pitch at a given air speed.

Abstract: A guidance system for a tractor drawn farm implement for providing an indication to the operator of the tractor as to variance of the implement from a desired course includes a pair of horizontally extending feeler rods supported by a shaft and having free ends extending in a parallel spaced relation to sense the crop and rotate the shaft if the implement veers off course. A light sensitive photopotentiometer coupled to the shaft has its output voltage varied as a function of the angular position of the shaft. A signal processing circuit responds to variation in the voltage of the light sensitive photopotentiometer to drive the needle of an analog meter to indicate the direction and amount of deviation of the implement from the desired course, the meter being mounted on the tractor and within the line of sight of the operator.

Abstract: A pressure gage for indicating pressure and variations thereof of a physical variable being monitored. The gage is provided with a circular dial having on the face thereof a pheripheral marginal portion or border green in color and graduations disposed internally of the green peripheral border. A pair of movable arcuate opaque cover plates, each made as an arc of an annulus, are disposed coaxial with the dial and graduations on the face of the dial. The plates are movably mounted for positioning thereof selectively in a circumferential direction of the dial for partially covering the marginal peripheral portion or border of the face of the dial. The plates are positionable selectively so that two opposed ends thereof define a space therebetween so that a green area of the border, which defines a range of selected pressure graduations on the dial, corresponds therewith.

Abstract: A viewing glass used through which measurements are displayed which comprises a groove (5) having a shape parallel to the movement of an indicator needle. Displaceable markers are placed in the groove in order to denote the limiting positions of the measurements being made.

Abstract: A sling has an indicator device which automatically registers the maximum permissible load which can be carried in accordance with the instantaneous angle of inclination of the strands of the sling.

Abstract: A sphygmomanometer gauge included a stationary dial having graduations indicative of different blood pressure values. A needle is turnable about an axis over the dial in response to changes in air pressure generated in the sphygmomanometer. A pair of adjustable members are mounted on the gauge for turning movement in either circumferential direction about the axis. Each adjustable member has an access portion which extends through the gauge housing to thereby permit independent and manual turning. A systolic indicator and a diastolic indicator are respectively mounted on the adjustable members for turning movement with the latter. Each indicator is operative to simultaneously indicate both a single value and a range of values of blood pressure.

Abstract: The improved indicating device is constructed from a single piece of resilient material such as Delrin or Teflon and includes a bifurcated friction portion that is disposed in a groove in the wrench. The friction portion is constructed so that the tines can be deformed to pass through a narrow slot and frictionally engage sides of the groove. The indicator member also includes an upstanding portion that is engageable with the pointer of the torque wrench to move the indicator as the pointer moves relative to the torque scale. Since the indicator member is in frictional engagement with the torque wrench, the indicator remains at the maximum torque after releasing the torque from the wrench and permitting the pointer to return to zero, thereby facilitating reading the maximum torque exerted.
