Abstract: ABSTRACT           The invention is concerned with an apparatus for the production of a composition for the direct nucleation of materials which are dissolved or suspended in a hydrogen-bonded liquid.  The apparatus of the invention comprises a first feeder for providing a flowing stream comprising a two phase mixture  of gas and a solution containing the hydrogen-bonded liquid and a soluble surfactant which has a HLB ratio greater than about 10 and is present in an amount up to about 3 times critical micelle concentration.          A micro-vortex forming and shedding device is arranged in the flow path of the stream for imparting to the stream a rotating laminar flow so as to form in the hydrogen-bonded liquid a plurality of micro-vortices which centrif-ugally entrap the gas therein and break into surfactant-stabilized spherical bubbles having a narrowly distributed size in the range of from about 12 to about 100 microns and a half-life of at least about 2 minutes.  The apparatus further comprises a time delay device downstream of the micro-vortex forming and shedding device for allowing a hydration layer to completely develop on each of the surfactant-stabilized gas bubbles formed, and a second feeder for adding a collector providing collector ions active to react with the materials such that these ions form an outer surface layer on the respective hydration layer of each surfactant-stabilized gas bubble and are movably held to the hydration layer by Coulomb forces.  The composition thus produced is particularly useful in the treatment of waters containing complex wastes, such as industrial laundry wastes.

Abstract: Abstract A measuring device detects a liquid component in refrigerant leaving the evaporator of a refrigerator or the like through the suction conduit (8). It is associated with a heating element (11), a tem-perature measuring sensor (13) and a reference value generator (14). The difference between the sensor signal and reference value are evaluated. The temperature measuring sensor (13) is in thermal contact with the tube (12) and is arranged at a spacing (a1) from the heating element (11) along the tube so that, in the presence of a liquid component in the refrigerant, the sensor signal is smaller than when the refrigerant is dry. In this way, the expansion valve can be controlled as a function of the moisture in the refri-gerant.            Fig. 2

Abstract: ABSTRACT         In a drilling monitor downhole transducers provide signals representative of torque (T) and axial load (F).  A downhole computer receives the torque and load signals and computes therefrom coefficients representative of drilling conditions and further circuitry combines the coefficients into a surface sendable signal indicative of drilling conditions.          Signals representing T and F are received from downhole transducers at input ports of the downhole computer.  From T and F measurements a relationship between T and F may be established, based on short term modelling.  From the system model, torque may be predicted and correlated with the measured values received from the torque transducer.  Values for the coefficients are computed and combined for sending from a transmitter to a receiver over a single low speed telemetry channel for display and recording at the surface.  The invention overcomes the problem of sending a vast quantity of data to the surface in order to monitor drilling conditions by running a downhole model of the drilling operation.

Abstract: Abstract A system for controlling overload of a chrominance component processor output includes means for comparing the processor output signal magnitude with a predetermined maximum desired magnitude value. Occurrences of the processor output signal magnitude exceeding the predetermined magnitude are identified as overload occurrences only if the duration of the excess continues for an interval of a width determined by the noise content of the processor output signal.  An overload control value is produced, corresponding to the average value of the processor output signal magnitudes over each such interval.  Means are provided for detecting the number of separate times within a given time period (e.g., field or frame interval) that an overload control value is produced.  Additional means, responsive to the overload control values and to the detected number, develop an overload control signal which is substantially representative of the average of the respective overload control values developed during one of said given time periods. Scaling of the overload control signal is effected in accordance with the output of the number detecting means.

Abstract: ABSTRACT OF THE DISCLOSURE         A dual stage hydraulic actuator (9)  for actuation of an expanding gate valve (10). The actuator is mountable to the valve housing and comprises a housing 40 which defines a piston chamber 41 and a primary piston (61)  slidably received therein. An actuator stem (23) connects the piston (61) to the valve gate assembly (20).          A secondary piston (77),  of smaller piston area than the primary piston (61), is slidably received in a piston receiving bore (75) which is formed in the fluid receiving face of the primary piston. A piston rod (80) connects coaxially with the piston (77) and extends through the end  (52)  of the actuator housing.  The actuator is responsive to hydraulic fluid pressure which when applied through an inlet (71) of the actuator housing to one side of the pistons (61, 77) drives the actuator stem and gate assembly to an operational open or closed position of the valve. A spring means  (66,  67)  in the piston chamber (41)  continuously urges the primary piston (61) in the direction which opposes the hydraulic-pressure. A stop element 85 on the piston rod 80 is adapted to engage the end (52) of the actuator housing to limit the length of the secondary piston stroke to a lesser length than that of the primary piston stroke whereby the effective piston area of the actuator (9) for driving the actuator stem (23) and the gate assembly (20) is reduced by an amount equal to the area of the second piston and there is a corresponding reduction in stress imposed on the actuator stem in the latter stage of actuator thrust.
