摘要： Distance measuring apparatus based on the pulse travel time method comprising a light pulse generator for generating periodic light pulses, a transmitting optical system for transmitting the light pulses, a receiving optical system for receiving the echo pulses produced by reflection of the light pulses at a target object, a photoelectric transducer for converting each echo pulse to an electrical measuring pulse, means for generating electrical reference pulses in predetermined time relationship to the transmitted light pulses, a time transformation stage operating by the sampling method and comprising a sampling pulse generator for generating periodic sampling pulses whose period is slightly different to the period of the transmitted light pulses, a first sampling circuit receiving the sampling pulses and the reference pulses and producing time-transformed reference pulses by periodically sampling a large number of successive reference pulses by means of the sampling pulses, and a second sampling circuit receiving the sampling pulses and the measuring pulses and producing time-transformed measuring pulses by periodically sampling a large number of successive measuring pulses by means of the sampling pulses, the second sampling circuit being directly connected to the output of the photoelectric transducer to receive the measuring pulses without intervening amplification, and time measuring means for measuring the time interval between corresponding edges of each time-transformed reference pulse and an associated time-transformed measuring pulse.

摘要： A method of measuring the bath level in a cool tubular mould utilized in a continuous casting process where a melt of metal to be cast is discharged from a container therefor into the mould via an immersion tube vertically extending into a bore through the mould to thereby establish the bath, there being an annular space between the immersion tube and the wall of the bore, and where the melt is soldified by the cooled mould and continuously withdrawn therefrom as a solidified bar. The method includes the steps of transmitting a series of light pulses from a transmission point in a first direction through an elongated tube horizontally disposed above the mould to the side thereof having a right-angle bend therein to a common deflecting mirror disposed at the bend; deflecting the light pulses from the common deflecting mirror into the annular space between the immersion tube and mould bore in a direction parallel to the vertically extending immersion tube and onto the surface of the bath; reflecting pulses from the bath surface through the annular space back to the common deflecting mirror; deflecting the reflected pulses from the mirror through the tube in a direction opposite to the first direction to a receiving point; electrically measuring the time interval between the instant of transmission of each transmitted light pulse and the instant of receipt of the corresponding echo light pulse to determine the bath level.

摘要： The invention relates to a continuous mixing silo and a method of operating it for the mixing of fine-grained material. The silo has a base provided with a plurality of zones which are supplied with aerating air in chronological sequence. Individual zones of the base are supplied with additional air in a pulse-like manner at specific intervals of time to achieve intensive aeration and mixing of the material. The additional air is supplied from a storage unit for a shorter period than the aerating air. Air taken from the storage unit is replenished during the time interval between pulses.
