Abstract: Screening apparatus that provides improved dewatering of liquid slurries includes a plurality of spaced, ridge-shaped flow disruption elements secured to the vertical side walls of the screening apparatus and a plurality of deflector elements disposed along the back convex surface of the screen extending across substantially the entire width of the screen parallel to and in engagement with bar-shaped members forming the screen. The flow disruption elements cause the thick slurry which otherwise sluices along the side guide surfaces of the screening device without being completely subjected to the screen action to be directed or diverted inwardly towards the active surface of the screen. The deflector elements cause the thruput water flowing down the back convex side of the screen which has passed through the screen to be diverted and captured in a container underneath the screen without running the entire length of the screen and tending to inhibit the water from passing through the screen on the downstream side of the deflector.

Abstract: The speed of a harvester is controlled by electrical signals derived from the functioning of the harvester. A first signal is obtained by sensing the density of some or all of the harvester output and a second signal is obtained from the drive for the harvesting apparatus. The first and second signals are compared to produce a difference signal with which the forward speed of the harvester is controlled so as to reduce the difference signal to a minimum. An indication of whether the actual speed of the harvester is correct or too slow or too fast at any instant, for a given crop loss is provided by three differently coloured lamps. The output from the straw shaker, the output from the sieve due to the air blast, and the output from the main sieve are sensed to provide output signals which are either treated separately or jointly to provide three individual signals or a composite signal relating to output density.

Abstract: An ionization flow meter which can determine with high accuracy the flow of a gas expressed as a gas velocity, volume flow, or mass flow and substantially independently of pressure, temperature and, as the case may be, moisture content. By applying the theory of corona discharges, data relating to the flow-determining factors such as ion mobility and gas density can be derived from the known measured voltage and current values using electronic means. For example, the slope S of the I-V characteristic curve can be determined from the measured values of voltage V and current I.

Abstract: A method and apparatus for regulating the differential rpm of two rotating parts, such as the external drum and internal worm conveyor of a worm centrifuge, undertakes an electronic measurement and sampling of the rotational during the course of operation of a particular device under speeds of each part and supplies this information to a microprocessor which calculates the respective rotational speeds of the parts and relays a signal to the drive device for one of the parts in order to maintain a preselected rpm differential between the rotational speeds of the two parts. Different characteristic curves are stored in the microprocessor for optimum rpm differential during the course of operation of a particular device under different conditions, such as for different sludge consistencies in the case of use with a centrifuge. If deviation of the actual rotational speed of one of the parts from the optimum value is detected, the microprocessor operates to return operation to the optimum values.

Abstract: A control unit tunes a tuner to a broadcasting station as determined by frequency data stored in a memory and then to another broadcasting station as determined by other frequency data stored in the memory while it applies a muting pulse to a muting circuit to mute an output from the tuner for a relatively short time. Subsequently, the tuner is tuned to that station having a higher reception level. An audio level sensor connected to the tuner is connected to one input of an AND gate whose other input is supplied with an output from the control unit originating from a command muting signal. When the sensor senses that an audio level of the tuner's output is approximating a zero level, the sensor supplies an output to the AND gate so as to permit the control unit to apply the muting signal to the muting circuit.

Abstract: PURPOSE:To detect the contact of a penpoint with an input panel surface by giving the depressing force, which is given to the penpoint in accordance with an input operation, to an electromechanical transducer. CONSTITUTION:When a pen pressure is applied to the tip of a pen holder 11, a stress is applied to both main surfaces of a piezo-electric rubber oscillator 14 through electric terminal plates 12 and 13 having projecting parts. The oscillation of the piezo-electric rubber oscillator 14 is suppressed by the oscillation absorbing action to reduce extremely a degree Q of sharpness of the oscillator. Consequently, an equivalent impedance is increased to stop the oscillation, and a DC voltage V0 becomes zero. That is, the output DC voltage VO is monitored to detect the contact of the penpoint with the input panel surface. In this operation, it is sufficient if only the stress due to the pen pressure acts upon the piezoelectric rubber oscillator 14, and the vertical movement, namely, the stroke of the pen holder 11 is unnecessary.
