Abstract: 47,617 CONTROL SYSTEM USING AN ALTERNATING CURRENT  CONTACTOR AND A DIRECT CURRENT OPERATED         INTERPOSING RELAY     ABSTRACT OF THE DISCLOSURE         An electrical control system employs a contractor having an AC operated coil, an interposing relay having DC operated electronic switching comprising a triac and a rectifier, and a manually operated pushbutton switch.  The coil is connected in series with the output of the triac and an AC power supply.  The rectifier is connected to the AC supply to form a source of direct current.  The push-button and the DC source are connected in series with the input of the triac whereby actuation of the pushbutton is operable to provide a low impedance path across the output terminals of the triac and activate the contactor.  The contactor is mounted in a housing having a plurality of exterior cavities adapted to receive a smaller housing containing the triac,rectifier, and associated components.          The control system is particularly suited for applications wherein the pushbutton switch is situated at an extended distance from the contactor.

Abstract: ABSTRACT OF THE DISCLOSURE      Subterranean slurry mining with one or more mining nozzles which, during mining, directs a high pres-sure jet of liquid into a granular ore matrix to reduce the ore to a slurry which is thereafter pumped to the surface by an eductor pump including a high pressure eductor nozzle. The drilling and mining apparatus includes several different types of hydraulic control systems which operates at or below system pressure and allows the ap-paratus to be changed between the mining and a drilling mode. During drilling, the liquid is directed through an open foot valve and drill bit into the well cavity being drilled to wash the cuttings to the surface at which time the mining and eductor nozzles are closed. During mining the control systems close the foot valve and control the opening of the mining nozzle (or nozzles) and eductor nozzle.     When the control system includes one or more control conduits that extend to the surface, the system may be used to modulate the eductor nozzle, and depending upon the control system being used to selectively open or close the mining nozzle, thereby controlling the pressure or draw-down in the cavity. Self-activating control systems are disclosed and are responsive to differences be-tween system pressure and cavity pressure when the foot valve is closed to modulate the eductor nozzle. Other self-acti-vating control systems may be used to selectively open and close a pair of mining nozzles without modulating the eductor nozzle, or with provision for modulating the eductor nozzle.     -1a-

Abstract: SELF CLEANING MANIFOLD            CONNECTION ? SECURE PUMP Abstract of the Disclosure One or a plurality of positive displace-ment slurry pumps are connected to common intake and discharge manifolds at a typical slurry pipeline pumping station.  Each pump is connected at its inlet by inlet piping from the intake manifold through an intake isolation valve with a flushing water inlet between the intake isolation valve and the pump.  Similarly, each pump is connected at its outlet by outlet piping to the outlet manifold through an outlet isolation valve with a pump drain between the outlet isolation valve and the pump.  Conventional pulsation dampeners are connected to the piping at least at the pump outlet and communicate a volume of gas under pressure to the pump for dampening of shock waves.  The inlet and outlet piping has a pipe length and slope between the pump on the high side to the station intake manifold and to the discharge manifold on the low side.  Settlement of virtually all of the particulate matter of the slurry clear of the intake and discharge isolation valves occurs when the pump is off.

Abstract: Abstract of the Disclosure Germanium detectors usable for charged particle spectroscopy and capable of enduring overvoltage without impairment are produced by first implanting phosphorus ions in a small dose of high energy and then implanting more phosphorus ions of lower energy in a large dose.  The low energy ions reduce surface resistance without impairing the improved properties of with-standing overvoltage that are provided by the high energy implantation.  The P+ contact is provided by boron ion implantation in a conventional manner. "Dead zones" on both sides have been found to have a very small thickness of 0.3 µm.

Abstract: Abstract of the Disclosure A low-profile survivable antenna suitable for military use is described.  Despite its small size, which might be one tenth of a wavelength, the antenna has reasonable transmission range for these applications.  Very little operator attention is needed in operation, since a special matching circuit within the antenna network enables effective impedance matching, over a 3:1 frequency range, without necessity of switching to different matching circuits over different frequency bands.  By including resistive components along with other passive inductive or capacitive elements, the reactance of the single matching circuit is made to effectively compensate the antenna's impedance over the entire frequency range.  The impedance of the circuit has a decreasing positive reactance which compensates for the decreasing negative reactance, with frequency, of the antenna.  Although the transmission effi-ciency of the matched antenna network is somewhat diminished by resistive losses, it is still satisfactory, and band switching with this matching circuit is completely eliminated.  By including a slender whip screwed into the top, the range can be doubled with no further changes.  The matching techniques to be described are most easily realized in the HF through VHF range (1-200 MHz).

Abstract: ABSTRACT OF THE DISCLOSURE      A process and an apparatus for monitoring or determining the mechanical and electrical synchroniza-tion tolerances in the angular drive chain of an element such as a weapon or a range finder, to be trained upon a target point by a periscope whose line of sight is directed to the target point by a reflector which is an-gulariy displaced.  The periscope, which can be the command periscope of a military vehicle such as a tank, has its line of sight initially directed at a mirror mounted on the directable element and in a zero setting of the angle drive, a reference mark in the ocular of the periscope is brought into coincidence with a reflected image of this mark (reflected mark) from the mirror.  The height and lateral positions of the mirror are adjusted for this coincidence and height and lateral deviations are then detected as the directable element is angularly displaced over its entire range (e.g. elevation).

Abstract: ABSTRACT OF THE DISCLOSURE         A heating apparatus incorporating a voice-actuated control system.  The control system operates in four (4) modes.          A first mode allows the user to select among previously stored cooking, defrosting or heating programs.  After a program is selected, the apparatus changes to a second mode wherein it makes an inquiry of the user related to the program selected.          After the inquiry is answered, in a third mode of operation, the apparatus changes to a fourth mode of operation to implement the selected program, as modified by a user's voice command in the third mode.  By requiring a user response from among a small class of possible responses for a given selected program, the apparatus is unlikely to begin a heating cycle without specific confirmation by a user and therefore its safety is enhanced.

Abstract: ABSTRACT OF THE DISCLOSURE         Digital data formed of binary bits of first and second values occupying consecutive bit cells of predeter-mined intervals are encoded such that successive binary bits of the first or second values are represented by predetermined separations between succeeding transitions.

When successive binary bits of the first value are sensed, a respective second transition is produced at a second reference point in a bit cell after sensing every 2 or 3 binary bits of the first value.  When successive binary bits of the second value are sensed, a respective second transition is produced at the second reference Point in a bit cell when at least two successive binary bits of the first value are followed by a binary bit of the second value and also after sensing every  3 or 4 successive binary bits of the second value, such that the last-mentioned second transition at the second reference point is separated from the closest first transition thereto by at least 1.5 bit cell intervals but no more than 4.5 bit cell intervals and successive ones of the second transi-tions are separated from each other by no more than 4 bit cell intervals.
