Abstract: ABSTRACT:       A surface acoustic wave bandpass electrical filter has double electrode input and output transducers (IP and OP) whose combined amplitude-frequency response has a fundamental passband centred on a frequency fo and a corresponding third harmonic passband.  An inter-posed multistrip coupler (MSA2) has strips (ST) with a mark-to-space ration of one-to-one and a centre-to-centre spacing .lambda.S2/2 chosen such that fo/fS2 is in the range 0.80 to 1.14 but excluding substantially 1.0, whereby a stopband in the amplitude-frequency response of the coupler (MSA2) between 2fS2 and 4fS2 suppresses the amplitude-frequency response of the input and output transducers (IP and OP) over a range of frequencies including 3fo?0.5fo.

Abstract: Abstract For use in connection with an electrically driven pump and  check valve  combination as  used  in municipal  water and sewage plants wherein the check valve prevents the reverse flow of water from the pipeline to which the pump supplies water into the pump, as would otherwise happen in case of a pump failure or breakdown or temporary power failure, there is provided a pump director with a first timer that starts the pump operating as soon as a control switch is closed and power is available and, as soon as the pump motor is energized,  a blue signal light flashes, but if pressure does not begin to build up in the pump outlet with the check valve closed, a flashing red signal will replace the blue and continue indefinitely until manually reset. If the pump does start to build up pressure, the flashing blue light  will  become  steady  whereupon  a  buildup  of  pressure continues and a flashing green light replaces the steady blue; and a second timer takes over under control also of a pressure switch to start opening the check valve and a limit switch is opened that cuts both timers out of the circuit and switches the flashing green light to a steady green light. In the event of an emergency, such as an unscheduled power failure, a damaged pump or motor, etc., a pressure switch losing pressure will trigger a fast emergency closing of the check valve and open the motor circuit.

Abstract: ABSTRACT OF THE DISCLOSURE      A tracking control device for a video tape recorder comprises a bimorph leaf on which a rotary playback head is mounted so as to be deflectable in a direction perpendicular to tracks to be scanned. A triangular wave signal generating circuit comprising cascaded flip-flops generates a substantially triangular wave signal which is supplied to the bimorph leaf to cause the playback head to wobble relative to the tracks. A detecting circuit detects an envelope signal in the signal reproduced by the playback head, and a phase comparing circuit which includes an exclusive-OR circuit compares the phase of this envelope signal with the phase of the triangular wave signal. The output of the phase comparing circuit is fed back to the bimorph leaf to effect tracking correction.

Abstract: A method of recovering chemicals and heat in sulphate spent liquor by means of A1(OH)3 or TiO2.n.H2O circulation and gasification of the waste liquor Abstract of the Disclosure The invention relates to a method of recovering chemicals and heat in sulphate spent liquor, wherein evaporated black liquor is granulated by means of circulated A1(OH)3 and NaA102 or TiO2.n.H2O and Na2TiO3, whereafter the granules are fed into a spent liquor gasifier where the temperature is from 700 to 1250°C. The granules which do not contain carbon, organic matter or sulphur are discharged from the gasifier, cooled with air and crushed, whereafter a part of the sodium aluminate or sodium titanate formed, if desired, is circulated to granulation and the remainder is dissolved in water. Hereby either NaOH and TiO2.n.H2O is formed which is precipitated or recirculated, or, when using A1(OH)3 circulation, an alkaline aluminate solution which can be directly used as absorption solution for H2S or cooking liquor in sulphate cooking. A1(OH)3 can also be precipitated from the solution and recirculated to granulation, whereby the remaining mother liquor mainly containing Na2CO3 is passed to causticizing. The gas mixture obtained from the gasification of spent liquor is cooled, whereafter H2S is absorbed from the gas into the NaOH solution or directly into the alkaline aluminate solution. The obtained solution is passed to the preparation of cooking liquor, and the flue gas is burned.

Abstract: ABSTRACT OF THE DISCLOSURE           A technique for measuring the distance between two points on an object along a laser beam axis, along with devices and methods of reducing measurement errors in such laser measure-ment systems are disclosed.  The laser measurement system includes a source laser, a rotatable penta-prism for reflecting the source through 90° and for generating a plane perpendicular to the source upon rotation thereof, and a carriage upon which the penta-prism is mounted to allow the penta-prism to be moved parallel to the source.  The position of the penta-prism along the source is adjusted until alignment with the two points on the object is detected, at which time the positions of the penta-prism which produce the alignments are noted on a scale parallel to the source.  A virtual detector probe including an optical detector, at least one mirror and a probe adapted to be placed on each of the two points causes the target point of the optical detector to be virtually located at the associated point on the object when the probe is placed on the desired point, by relatively disposing the optical detector, the mirror and the probe at predetermined locations.  The virtual location of the target point of the optical detector at the desired point will be substantially unaffected by movements of the optical device as long as the probe remains on the desired target.  In this manner, an optical detector may be virtually placed at locations on a body to be measured which cannot otherwise be physically accomplished.  The virtual detector probe may alternatively be used as a carriage yaw compensator for compensating for any errors in measurement due to non-linearities in the carriage upon which the penta-prism is mounted

An originating processor transmits circuit setup request control words including an address defining a destination processor, to a control word switch via control time slots through a time-multiplexed switch.          The control word switch responds by establishing a communication path to the destination processor via the time-multiplexed switch and then transmitting a status signal to the originating processor indicating that the path has been established.  In response to the status signal, the originating processor begins transmitting the control message control words which comprise a control message.  Advantageously, the control word switch does not store entire control messages before conveying them to destination processors.
