An indicating recorder comprising a housing unit, an internal frame unit and an electric power source unit. The housing unit includes a single-swing front door and is made from a square prismatic housing formed by bending a thin plate. The internal frame unit is positioned in the vicinity of the inlet of the housing unit and is rotatable in a direction opposite the front door so as to be drawn out toward the front. The internal frame unit has left and right side plates and coupling beams between...

An indicating instrument particularly for use in a vehicle comprises a first element which is moved behind a window of the instrument such that the amount of the first element visible in the window is indicative of the distance travelled by the vehicle, and a second element that is moved in dependence upon the speed of the vehicle and such that the second element is obscured from view in the window by the first element while a predetermined relationship exists between the speed and distance.

A pair of upright stands are provided and include enlarged bases by which the stands may be supported on variously elevated support surfaces. Each stand has a vertically elongated support mounted thereon for adjustable vertical positioning therealong and each stand has a scale thereon by which the positioning of the support therealong may be precisely determined and adjusted as desired. Each support includes an upstanding transparent tube section and the lower ends of the tube sections are conne...

A device for indicating the center of a hole or for indicating a point, line, etc., the device including a pointer and an element having a pointed end, the pointer and the element being interconnected for effecting oscillatory movements relative to one another. The device may have an indicator dial for direct reading or a fixed pointer for layout work.

An indicating apparatus provides an indication of three ranges, for instance, over-exposure, appropriate exposure and insufficient exposure, for a photographic camera, by continuously energizing a first lamp, by continuously energizing a second lamp and by alternately energizing the first and second lamps with a preset frequency, respectively. The frequency can be maintained at a constant value, irrespective of the selection of the exposure value.

There is disclosed an indicating device for facilitating chart reading, comprising a pair of tapes each extrudable from a tape housing, the two housings being hinged together so that they may be swung to a side by side position or to a position in which the tapes when extruded are perpendicular and intersecting each other. Placing the tape intersection at markings of the chart facilitates reading of the items at the vertical or horizontal coordinates.

An inclinometer comprising a sensing unit and a readout unit which in use are remotely connected together through a cable, the sensing unit including two inclination sensors with sensing axes arranged at right angles and associated electronic circuitry to provide output signals which are fed to the readout unit through the cable. Also, along each of three coordinate axes there is provided a magnetic sensor, and the readout unit comprises means for converting AC signals from the inclination and m...

An indicating instrument wherein the housing accommodates a moving-coil instrument whose pointer travels along one surface of an elongated prism. The one surface carries a straight scale and another surface of the prism is mirrored to reflect the images of the scale and of the tip of the pointer toward the front side of the housing. At least some graduations of the scale constitute openings or cutouts which permit observation of the tip in corresponding angular positions of the pointer.

A resettable character indicating device is of the type, for example, usable in an automobile for recording mileage at a given time. A disclosed embodiment contains three windows or apertures for indicating the unit, tens and hundreds digits of mileage. The device is made from a single sheet of cardboard or the like which is punched at predetermined locations with apertures or holes for receiving an axle bearing member and character bearing discs. Certain of the apertures are located to provide ...

An indicating device for giving metric measurements with a feed screw of inch fractional pitch or vice versa comprises a handwheel for the screw, an index scale and a gear drive, preferably epicyclic, between the handwheel and scale. The ratio of the gear drive provides the conversion. There may be another index scale and another gear drive, the second scale indicating feed in the same measurement system as the screw. Either indicating system may have a supplementary geared scale so that there i...
