A device for converting the value in a mechanical register into electrical output signals. The value in the register is transferred to coded means, each one cooperating with a number of wires and set to an operative or inoperative position, (being able to cover or uncover apertures in a stationary disc). A rotating sensing finger, comprising optical fibers, scans the apertures in sequence and depending on the apertures being covered or exposed transmits light from a stationary light source to a ...

The invention provides a converting assembly, cooperating with a general purpose tractor, for periodically interchanging an implement configured for side-to-side motion with one configured for a tilting motion about a horizontal axis. An illustrated embodiment includes a frame, rigidly but readily removably attached to the tractor lift frame members. A motion connector, pivotally mounted to the frame, cooperates with the tractor tilt cylinder and the implement to convert extension and retraction...

A converting press for paper or cardboard sheets including a waste stripping station and/or a blanking station with a pull-out chase (1, 2, 3, 4). A pair of horizontal transverse rails (5, 11) supports an upper stripping tool for a waste stripping operation, or a blanking tool for a blanking operation. The first rail (5) is fixed relative to the chase and the second rail is movable in a longitudinal direction. The profile of the rails allows receiving and maintaining in an operational waste stri...

A digital component signal derived from a video camera and the like is converted into a digital composite signal such as a color TV signal by a low-cost converting apparatus with a simple circuit arrangement. The converting apparatus includes an encoding circuit for encoding the inputted digital component signal to produce a digital component signal having a first sampling frequency equal to a sampling frequency of a luminance signal of the inputted digital component signal, an oversampling filt...

A multi quantum well layer has a lamination of first and second quantum well layers each sandwiched between barrier layers and defining a quantum well. The band gap of the second quantum well layer is larger than the band gap of the first quantum well layer. Current is flowed through the multi quantum well layer from a pair of electrodes. A first optical system input inputting a signal light wave to the multi quantum well layer via an input plane of the multi quantum well layer. A second optical...

A process for converting a copper sulphide matte and/or a copper sulphide concentrate to blister copper is described which comprises the steps of adding the matte and/or concentrate together with a suitable flux to an agitated molten bath containing molten slag phase and a molten metal phase; injecting by means of a submerged lance an oxidizing gas capable of reacting with the matte or concentrate to form a low sulphur blister copper phase, slag and sulphur dioxide; controlling the injection of ...

Power conversion system includes power amplifiers that receive D.C. potentials from rectifying and filtering circuitry that direct couple the power amplifiers to the conventional A.C. power lines. An output transformer couples the power amplified signal to an output terminal. A feedback network couples the output terminal to one input of a signal combiner that has a reference input terminal for receiving a reference signal. An isolation amplifier couples the output of the signal combiner to the ...

An audio converting device including a digital high-pass filter, an expander, a digital low-pass filter, a delta-sigma modulator, a digital-to-analog converter, an analog low-pass filter and a gain control unit is provided. The digital high-pass filter in this invention can filter out a direct-current component of digital audio data such that the production of noise is avoided when the volume is adjusted by users.
