Abstract: Instruments are readable in either feet or meters by printing a metric altitude scale on the inner surface of a rotating protective crystal that shields the English altitude scale and the indicating needle. The metric altitude scale covers 1,000 meters and extends 33.7.degree. beyond a full circle. A series of kilometer index marks is formed at intervals of 33.7.degree. on the face of a bezel which surrounds the English scale. To use the metric scale, the user holds the bezel to align the index arrow line with the appropriate kilometer index mark, according to the user's elevation. Subsequently, if the needle moves beyond either limit of the metric scale, it is only necessary to rotate the crystal 33.7.degree. in the appropriate direction, thereby aligning the "0" meter line with the adjacent index mark.

Abstract: The present invention discloses a device which will automatically display the metric equivalents and their appropriate dimensional designations of any given metric measurement. In the preferred embodiments shown, the device may be either an electronic keyboard-display console apparatus or a mechanical device using printed rolls.

Abstract: A system for entering a temperature setting into a memory store and for displaying it, wherein the temperature setting includes a temperature level portion and a temperature scale portion. The temperature level portion corresponds to the temperature at which a microwave oven, for example, is to be set and the temperature scale portion indicates whether the temperature level portion is calibrated in degrees Fahrenheit or degrees Celsius. The temperature level is inputted through a decimal keyboard and a key signal encoder. Gating circuits transfer the temperature level from the key signal encoder and the temperature scale from a temperature unit code generator to a memory under control of a preprogrammed instruction data generator. A display circuit and display unit are coupled to the memory for displaying the temperature setting.

Abstract: A conversion mechanism is attached to a speedometer in such a way that the input into the speedometer can be mechanically altered to establish a conversion ratio between a first system of units and a second system of units and the speedometer is indexed to display the speed measured in either system of units. The conversion apparatus is switchable between two modes to cause the speedometer to register selectively either of the two systems of units, and the apparatus is designed to be interposed at any point along the mechanical drive or input for the speedometer.

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.

Abstract: A portable device to determine highway marker locations including an enlarged disc dial having graduated scale markings on each side thereof and therearound representing increasing and decreasing highway mileage markers, respectively, and smaller disc dials superposed on either side of and centrally rotatably and lockably mounted thereon. The latter are provided with scale markings therearound representing vehicle odometer readings. To keep track of a vehicle's highway location, the user visually notes the last highway marker passed and rotates the small dial until the last two digits of the vehicle odometer reading indicated on the dial scale are aligned with the scale marking on the appropriate large intermediate dial (either increasing or decreasing, depending on direction of travel) corresponding with that mile marker, and the three discs are locked thereat.

Abstract: A fully adjustable concentric dial indicator comprises a first annular scale member which is adapted to carry indicia around the periphery thereof defining a first circular scale. The second scale member is disposed coaxially of the first and is adapted to carry indicia around the periphery thereof defining a second circular scale. Friction clutch means couple the scale members to a support for selective rotation of the scale members relative to the support in either direction about the common axis. The friction clutch means includes a manually engageable ring member to which only the first of the scale members is fixed and which is rotatable about the common axis of the scale members against the effect of the friction clutch means associated with the first scale member. First and second concentric rotatable shafts are aligned with the axis and respectively carry first and second pointers.

Abstract: An adhesive label for the application of kilometer per hour speed values to a speedometer bearing miles per hour indicia bears two sequences of numerical indicia, one being speed values in miles per hour and the other being corresponding values in kilometers per hour. The front sheet of the label has an adhesive coating protected by a peelable backing sheet and is severed to permit peeling from the backing sheet of separate portions of that front sheet, each such portion bearing a kilometers-per hour value and optionally a corresponding miles per hour value so that each such portion can be applied to a speedometer cover glass in an appropriate position. Usually, the front sheet of the label is severed or perforated between the two sequences of indicia. Alternatively, the miles per hour indicia can be printed on the backing sheet so as to be visible through a transparent front sheet.

Abstract: A compact rotary instrument for accurately measuring small movements of a machine tool leadscrew, the instrument having one continuous decimally divided scale which indicates the measurement in either the metric or the inch system as selected by an operator. The instrument encloses a gear system which can be changed from a direct drive condition in which the rotary motion of the leadscrew drives an annular scale at a 1:1 ratio to an indirect drive condition in which the rotary motion of the leadscrew drives the scale through a gear train having two externally formed ring gears and two pinion gears carried on a stub shaft, at a 1.27:1 ratio. The selection is by means of an annular rotatable selector having two spaced marks formed thereon against which the scale can be read by an operator, the rotational positions of the selector and the spacing of the marks being such that when direct drive is selected only one mark is visible by an operator and when indirect drive is selected only the other mark is visible.
