Abstract: 20.1926 DII          METHOD AND APPARATUS FOR ACOUSTIC LOGGING              OF A  BOREHOLE      A method and apparatus are described for preferentially exciting for extracting late arrivals at low frequencies in an acoustic investigation of a borehole.  The late arrival may be the Stoneley wave whose amplitude is derived by measuring the energy in a predetermined frequency band of a waveform produced with a low frequency transmitter-receiver system.  The transmitter produces a highly damped acoustic pulse whose frequency spectrum is selected to preferentially excite a late arrival such as the Stoneley wave and/or tube wave with wavelengths which are significantly greater than the diameter of the borehole while preserving measurable earlier arrivals at higher frequencies.  A receiver system is used which provides a generally flat frequency response including low frequencies to produce waveforms of both the earlier arrivals at high frequencies and late arrivals at low frequencies with sufficient extractable amplitudes throughout a wide range of borehole and formation conditions.  A method for generating the display are described for the investigations of the late arrival.

Abstract: IMPROVED OUTRIGGER                ABSTRACT OF THE DISCLOSURE           A rod pivotally attaches to the side of a boat, extends outwardly therefrom, and connects with the free end of an oar together with a restraint to provide a fulcrum remote from the side of the boat as the oar is pulled from fore to aft positions through a stroke.  The restraining means, such as a forward link extending outwardly from the side of the boat and a control link connecting the outer ends of the rod and forward link, allows aft movement of the fulcrum during the stroke.  The position of the fulcrum together with its aft movement reduce the component of the force normal to the blade that acts normally to the direc-tion of motion thereby increasing the propulsive efficiency. Alternative restraining means, such as a gear and pinion or pulley arrangement or the like, can be used to control aft movement of the fulcrum.

Abstract: A SPHERICAL ACTIVATED CARBON HAVING LOW DUSTING PROPERTY AND HIGH PHYSICAL STRENGTH AND PROCESS FOR PRODUCING THE SAME  ABSTRACT            The specification discloses a process for producing spherical activated carbon particles having high strength and low susceptibility to dusting.  The particles are produced by heating a mixture of pitch (having a softening point of 50-350°C, a carbon content of 80-97%, a hydrogen/carbon atomic ratio of 0.3-2.0, and a nitrobenzene-insoluble matter content of below 60%), at least one aromatic compound as a solvent miscible with the pitch, and 0.1-10 wt. % (based on the amount of the pitch) of at least one polymer of chain hydrocarbon or a copolymer having the chain hydrocarbon moiety as a major component thereof.  The resulting liquified mixture is then dispersed in an aqueous medium containing a suspending agent, thereby producing microspheres of the mixture dispersed in the solution.  The microspheres are then treated to the removal of solvent, infusibilization, carbonization and activation.  The resulting carbon is particularly useful in those cases where the formation of dust is harmful or dangerous.

Abstract: 1          PHB. 32,635.   ABSTRACT:           A voltage clamping circuit for use in coupling line voltage signals to logic control circuitry used in domestic appliances includes a voltage dropping resistor coupled between input and output terminals.  A first enhancement mode MOS transistor is coupled between a junc-tion of the resistor and the output terminal and the VDD line.  The gate of the first transistor is connected to the junction, so that when the voltage at the junction rises to a threshold voltage above VDD the first transis-tor is rendered conductive and clamps the positive line voltage cycle.  A second enhancement mode MOS transistor is connected between the junction and the VDD line and its gate is connected to a biasing means which holds the second transistor nonconductive in response to the line voltage going negative until the junction is just above the VSS level, whereafter the second transistor turns on and clamps the input above VSS.
