Abstract: ABSTRACT      Agglomerates of water insoluble builder molecular sieve zeolites are made by tumbling or otherwise suitably mixing very finely divided ion exchanging zeolite powder and a water soluble binder, such as starch, pre-ferably in the presence of a small amount of moisture sufficient to promote desirable agglomeration of the finely dived ion exchanging zeolite particles and the binder into essentially spherical particles, preferably in the 6 to 140 mesh range.  The agglomerates are readily disintegrated when agitated in water and rapidly release the separated very finely divided insoluble builder particles to allow them to remove hardness ions from the water.  The dispersible and disintegrable agglomerates are especially useful in heavy duty detergent compositions wherein the zeolite of the agglomerates provides all or a substantial proportion of the builder con-tent.  Because of their ready disintegrability the agglomerates quickly release very finely divided ion exchanging zeolite particles, which re-move calcium hardness ions from wash waters, improving detergency of the composition and at the same time, because of the very small particle size thereof, passing through laundered fabrics without depositing thereon to objectionably discolor or whiten said laundry (especially colored laundry). Because their particle size is about that of the balance of the detergent composition the builder agglomerates are also nonsegregating and non-dusting.  Preferred zeolites are amorphous but crystalline zeolites, of the molecular sieve type, are useful too.  The amorphous zeolites are addition-ally useful in sorbing sticky detergent materials and allow the manufacture of free flowing and non-dusting products without the need for spray drying or other drying operations.

Abstract: AUTOMATIC BIAS CONTROL CIRCUIT     FOR INJECTION LASERS     Abstract of the Disclosure An injection laser is automatically stabilized so that the laser operates above threshold when the laser current is modulated.  The invention makes use of the fact that the laser junction voltage saturates at currents above the threshold.  A signal which modulates the laser current and causes the laser current to fall below the threshold level therefore results in a change in the junction voltage.  These changes in the junction voltage are monitored and used to increase the bias current so that the laser operates above threshold.

Abstract: TITLE     AN ULTRASONIC AIR DATA SYSTEM     INVENTORS     P.H. Barry MacLennan Graham A. Ireland William J. Werba ABSTRACT OF THE DISCLOSURE         The ultrasonic air data system determines the rela-tive velocity of an aircraft with respect to the medium in one, two or three directions.  In addition, it may determine the speed of sound and the approximate temperature.  In the one direction system, a first ultrasonic transducer transmits a pulse to a second transducer where it is detected and reflected back to the first transducer and again reflected to the second transducer.  The pulse transit times for each direction are determined, and the relative velocity, the speed of sound and the approximate temperature are provided as a function of the transit time.  In the two or three direction systems, three or four transducers are positioned in a two or three dimensional configuration.  In the first half cycle, the first transducer transmits a pulse to the second where it is reflected to the third or last transducer in a two-dimension system and then to the last transducer in a three-dimension system.  In the second half-cycle,  the last transducer trans-mits a pulse which is reflected through the transducer arrange-ment to the first transducer.  Transit times for pulse travel in each direction between pairs of transducers are determined, and relative velocities, speed of sound and approximate temper-ature are provided as a function of these transit times.

Abstract: PRESSURIZED LIQUID COOLING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE Abstract of the Disclosure A liquid cooling system for an internal combustion engine includes a conventional radiator and circulating system and pressure cap, the latter having pressure and vacuum relief valve components for limiting the maximum operating pressure of the system and for limiting negative pressures to avoid damage during cooling after engine shutdown.  A second, temperature responsive, pressure relief valve provides a lower system relief pressure as long as the temperature of the coolant in the radiator top tank remains below a certain level.  When that level is exceeded, a thermally actuated valve excludes the second pressure relief valve from the system and maximum operating pressure is then limited, at a higher level by the valving of the pressure cap.          In an alternative embodiment, an infinitely variable pressure relief valve responsive to and controlled by changes in coolant temperature replaces the fixed second pressure relief valve and its thermal actuator.  As the temperature of the coolant increases, the set point of the variable pressure relief valve also increases and the system relief pressure varies automatically with the coolant temperature over a range of pressures whose upper limit is significantly greater than the set point of the relief valve in the pressure cap so that maximum system operating pressure is still limited by the pressure cap.

Abstract: Abstract The invention is a device for controlling a sound reproduction transcriber which provides alternate playback intervals and stopped intervals.  The playback interval length in words is manually selectable by a secretary or instructor by means of a phrase length selecting means (46).  Similarly, the average word reproduction rate in selected by a selector means (60). The device meters the reproduced words during the playback interval with its syllable detecting and counting means (16) and initiates the stopped interval at the first audio pause after the selected number of words have been played back.  The required total cycle time is computed is a calculator circuit (70) by effectively dividing the number of words played back during the playback interval by the selected average word reproduction rate.  A timer (84), which counts the time elapsed since the playback interval was initiated, has its counted time compared to the computed total cycle time in a time comparator (78) so that the stopped interval is terminated, the circuit is reset and the playback interval is again initiated upon coincidence of the computed time and the elapsed time.
