摘要： The incremental measuring and machine control system comprises an incremental scale and an auxiliary track extending beside said scale along the same and provided with at least one reference mark in register with a predetermined point of said scale. A scanning unit comprises scanning means for scanning said scale and for generating analog signals in response to the scanning of said scale. The scanning unit comprises additional scanning means for scanning said reference marks and for generating reference signals in response to the scanning of the reference marks. A processor derives digital signals for said analog signals and delivers the digital signals to a counting or display unit which is controlled by said reference signals or by signals derived therefrom. To eliminate the need for separate limit switches or other limiting means in the machine control system, the auxiliary track is provided with control marks and the processor comprises a processor for distinguishing between the reference signals and between control signals generated by said additional scanning means in response to the scanning of said control marks. Said control signals can then be delivered to a control output of the processor and used to control switches for arresting or reversing drive means of the machine control system.

摘要： The instrument for measuring lengths comprises a carrier, a rule secured to that carrier and provided with a scale, and an optoelectronic scanning unit comprising a scanning plate, light emitters and light receivers. The scanning unit is movable along the scale by means of an actuating member, which constitutes a feeler. Auxiliary tracks are provided for guiding the scanning unit along the scale. A part of the scanning unit is connected to the actuating member by means which are yieldable transversely to the longitudinal direction of the scale. Auxiliary tracks are provided for guiding a part of the scanning unit along the scale. The overall structure is simplified and reduced in overall size and a change of the clearance between the scanning plate and the rule is prevented in that only the scanning plate is guided in engagement with the auxiliary tracks, one of which is constituted by the rule. The light emitters and the light receivers of the scanning unit are secured to the actuating member, which is connected to the scanning plate by means which are yieldable transversely to the longitudinal direction of the scale.

摘要： A hand-held measuring implement comprises a transparent scale-carrying member provided with a graduated scale. A reading unit is movable along said scale in unison with a feeler and comprises photoelectric receivers, which scan the graduated scale through respective line screens. The graduated scale is illuminated by light sources, which are disposed on the same side of the graduated scale as the receivers and are movable with the latter. Signal-processing circuitry is provided for processing the indicating signals generated by the receivers. The implement comprises also a display device and power supply means. To improve the light efficiency and to reduce the power consumption of the light sources and to reduce the effects of an ageing and soiling of the scale-carrying member, the latter is wider than the graduated scale and provided on the side opposite to the line screens with a reflecting covering. The light sources are arranged to direct light against that portion of the scale-carrying member which is laterally spaced from the graduated scale so that said light is reflected by the reflecting covering and subsequently transmitted to the receivers through the graduated scale, which is provided on that side of the scale-carrying member which faces the line screens, and through the line screens.

摘要： An incremental measuring system comprises a scale member provided in one track with a measuring scale, and an optoelectronic scanning unit for generating measured-valve signals in response to a scanning of the scale. The scale member is provided in an additional track with two or more reference marks and the scanning unit is operable to scan the reference marks and to generate reference signals in response to the scanning of the additional track at one or more selectable reference points provided with such reference marks. The scale member and the scanning unit are encapsulated in an enclosure, which is formed with a slot, which is covered by a seal. An actuating member for the scanning unit extends through the slot past the seal. Covers for covering at least part of the reference marks are provided and are adapted to be inserted and/or removed into and from the enclosure or shifted along the tracks by a positioning member, which extend through apertures formed in the enclosure. The covers are used to select the reference points which are entirely exposed for being scanned by the scanning unit. The apertures are closed and sealed or are adapted to be closed and sealed.

摘要： A method of digitally measuring displacement increments in which, for the relative displacement of a scanner and a scale having regularly spaced graduations each defining an increment of displacement, correction values and the signals are stored at respective addresses corresponding to the relative displacement and respective locations on the scale, only where the correction exceeds a predetermined threshold value. During the measurement, the measured values, which can correspond to each graduation and to interpolation values between each graduation and the next graduation to be scanned, are corrected with the corrected value addressed as each location is reached.

摘要： The linear incremental measuring system comprises an incremental scale, a scanning unit for generating two analog signals, which are displaced in phase in a direction depending on the direction of the scanning movement, and a processor for generating digital signals from the analog signals and for delivering said digital signals to a bidirectional counter, which is used to control a display device and/or a control device. In order to detect in a simple manner the velocity of the scanning movement relative to the scale and to generate a voltage that is proportional to that velocity and can be used to control a machine, digital signals derived from the analog signals are delivered to a digital-to-analog conversion circuit, which delivers an analog voltage that is proportional to the velocity of the scanning movement and has a polarity that is dependent on the direction of that movement.

摘要： A sealed instrument for measuring lengths comprises a carrier, a scale mounted on said carrier, and an optoelectronic scanning unit including a scanning plate, light emitters and light receivers. The scanning unit is adjustable along the scale by means of a feeler, which includes an actuating member. A correcting device is provided, which includes a deformable correcting template and a template follower for scanning the correcting template and for adjusting the scanning plate relative to the actuating member in the direction of the scanning movement. In order to reduce the overall expenditure, to simplify the correction and to increase the reliability of operation and the accuracy of the measurement, only the scanning plate is operatively connected by an adjusting mechanism to the template follower and is adjustable relative to the remaining parts of the scanning unit in dependence on the configuration of the correcting template.
