In meter movements wherein a pointer moves across a scale in response to relatively small deflections of a Bourdon tube, bellows or the like, improved means comprising motion transferring means operatively connected to the transducer and connected to the pointer wherein the pointer is rotated relative to the scale by operation of a frictionless and gearless mechanism converting the transverse movement of the transducer to rotation of the pointer.

The present invention relates to an indicating apparatus which has light-refractive sections comprising concave and convex sections that are formed of ultraviolet-cured resin having light transmission properties and are disposed on a back surface of an indicating plate and adjacent an illuminating light source, is easy to manufacture, and, furthermore, is capable of obtaining the same three-dimensional illumination effect as those processed into a form of lens.

An indicating apparatus for providing a visual linear output signal related to a measure variable in response to a voltage signal received from a sensor which measure the variable and provides an output voltage signal analogous thereto.

A device for indicating the angular position of a rotatable shaft and having a first indicator dial secured to the rotatable shaft for rotation therewith. The device includes a brake having first and second braking positions. The brake when in its first braking position preventing rotation of the rotatable shaft except upon application of a force of a relatively large magnitude to the shaft. The brake when in its second braking position preventing any rotation of the rotatable shaft.

An indicating potentiometer with a potentiometer having an input rotor rotatable through ten revolutions between internal limit stops of the potentiometer for setting the potentiometer output voltage, a rotary counter geared to the potentiometer rotor for displaying a readout of the potentiometer setting through an available counter readout range corresponding to the potentiometer voltage range, a manually settable drive shaft for simultaneously setting the rotor and counter and a pair of auxili...

A device for indicating the angular position of a rotatable member of a type adapted for mounting on a panel. A bracket for mounting the device on the panel includes a first axially extending tang adapted for insertion into a slot formed in a first portion of the indicating device. The slot includes two spring fingers extending radially inward. The spring fingers engage the tang to prevent the indicating device from rotating relative to the panel.

An indicating device is provided which comprises a liquid crystal element in plate form disposed in the front part of the device and having a light transmission factor which changes considerably with variation of the voltage applied thereto, a detecting switch for detecting variation of a quantity or condition to be detected, a light emitting diode disposed in the rear of the liquid crystal element, and a reflecting plate for reflecting an external light, wherein the liquid crystal element is co...

An indicating instrument for use in radio or television receivers has one or two elongated prisms with an exposed surface, a mirrored surface and a further surface which is adjacent to the straight terminal of a pointer pivotable by a moving-coil instrument. The pivot axis of the pointer is parallel to the terminal and to the further surface of the prism. One or more scales are positioned in the housing of the indicating instrument in such a way that they are either directly observable by lookin...

An indicating device such as is used to display automobile service station price data and such as is used as a score board for athletic events includes a suitable mounted base plate (1) (50) in which a plurality of slots (2-9) (51-56) are formed for receiving respectively a plurality of semirigid ribs (35-38) (35a-38a) having rib mounting grooves (42,43) whereby the ribs are slidable longitudinally into the slots, each rib being provided with tape positioning grooves (44,45) for slidably receivi...

An indicating thermometer comprises a molded single piece main member including a disc-like portion and a hollow stem portion having an end wall, and a temperature responsive assembly including a shaft, a plug and a bimetallic helical coil having its ends secured to the shaft and the plug which is secured in the main member, wherein the shaft is journalled for sliding and rotation in the end wall of the stem portion of the main member and in the plug which is secured in the disc-like portion of ...
