Abstract: A device for use in the training of a dog, for example to dissuade the dog from barking. The device, which is carried by the collar of the dog, has a tank which carries a substance that affects the special senses of the dog, particularly the nose and the eyes. The tank has a valve which, when activated, releases a spray of the substance in the region of the head of the dog. An electronic circuit is provided to actuate the valve of the tank when desired, for example, in response to a signal from a microphone with a filter which is sensitive to the frequencies that correspond to those of the bark of the dog. The electronic circuit may also be responsive to a signal from a remote transmitter, to permit a trainer to actuate the release of the spray when desired as part of the training of the dog, and a selector switch may be provided to selectively permit the release of the spray either on command from a remote location or automatically in response to the barking of the dog. The special substance in the tank may either be in the form of a pressurized aerosol of the substance, or a pump may be provided to pressurize a normally unpressurized substance at the time of its release.

Abstract: MECHANIZED LOOP TESTING USING A LOCAL METALLIC ACCESS PORT            Abstract In a telephone loop system where loops are connected to a remote switch which in turn homes on a host switch via a carrier system and where the distance between the ends of the loops and the host switch exceeds a predetermined distance, the loops may be tested by locating the test apparatus remotely from the host switch.  In order to establish a connection between the test apparatus and the loops, signals are transferred over two dedicated carrier channels between the test apparatus and the host switch via two applique circuits.  These applique circuits make it appear to the test system as if the remote switch (or carrier RT or concentrator) support a test trunk interfaces.  This makes it possible to use test hardware designed for use with class 5 offices with these remote units without modification to the test system itself.

Abstract: ABSTRACT OF THE DISCLOSURE       APPARATUS FOR DETECTING AN INTERFACE IN FLUIDS    A probe for detecting separated sludges such as in sewage, is axially elongated and has a large number of LED-phototransistor pairs axially spaced thereon in facing relationship with a gap therebetween. The phototransistors are commonly connected, and the LEDs are sequentially fired by multiplex switching located within the probe. Since the quiescent current of the phototransistors is normally low, the common phototransistor output will essentially be proportional to the amount of light reaching a specific phototransistor. The output signals are processed to automatically locate an interface between separated sludge and clarified liquor. Circuitry is included to adjust the power level at which the LEDs are activated responsive to the output from selected ones of the phototransistors, for the purpose of reducing beam intensity if the sludge becomes thin, and also for increasing the intensity to overcome fouling of the windows of the probe.

Abstract: "IMPROVED HEAT TRANSFER TUBE HAVING INTERNAL RIDGES, AND METHOD OF MAKING SAME"                         ABSTRACT            Improved heat transfer tube and method of making same has mechanical enhancements which can individually improve either the inner or outer surfaces or which can cooperate to increase the overall efficiency of the tube.  The internal enhancement, which is useful on either boiling or condensing tubes, comprises a plurality of closely spaced helical ridges which provide increased surface area and are positioned at an angle which gives them a tendency to swirl the liquid.  The external enhancement, which is applicable to boiling tubes, is provided by successive cross-grooving and rolling operations performed after finning.  The finning operation, in a preferred embodiment for nucleate boiling, produces fins while the cross-grooving and rolling operation deforms the tips of the fins and causes the surface of the tube to have the general appearance of a grid of generally rectangular flattened-blocks which are wider than the fins and separated by narrow openings between the fins and narrow grooves normal thereto.  The roots of the fins and the cavities or channels formed therein under the flattened fin tips are of much greater width than the surface openings so -that the vapor bubbles can travel outwardly through the cavity and to and through the narrow openings.  The cavities and narrow openings and the grooves all cooperate as part of a flow and pumping system so that the vapor bubbles can readily be carried away from the tube and so that fresh liquid can circulate to the nucleation sites.  The rolling operation is performed in a manner such that the cavities produced will be both larger and smaller than the optimum minimum pore size for nucleate boiling of a particular fluid under a particular set of operating conditions.

Abstract: SYSTEM AND METHOD FOR CONTROLLED                     DIRECTIONAL DRILLING                  Abstract of the Disclosure A system and method for controlled directional drilling utilizes a system approach to design the hardware for drilling according to the well plan.  The bend angle of a bent housing, connected between the bit and a down-hole motor, the diameter of a plurality of stabilizers and placement of the stabilizers with respect to the drill bit are selected and predetermined on the basis of the desired well plan.  With the use of an MWD, the direction of the progressing borehole is tucked from the surface.  Direction changes as required are controlled from the surface simply by controlling rotation of the drillstring.  For curved path drilling only, the down-hole motor is rotated, causing the borehole to travel along the curve determined by the bend angle in the bent housing and the diameter and location of the concentric stabilizers. When straight hole drilling is required, both the down-hole motor and the entire drill string are rotated, effectively nullifying the effect of the bend angle in the bent housing.
