Abstract: ABSTRACT OF THE DISCLOSURE:          The present invention concerns an apparatus for perform-ing widenings by milling in drill-holes and perforations, which is characterized in that it comprises an elongated body provided with an excentric longitudinal performation where another elongat-ed body is installed, which in turn is provided with another excen-tric longitudinal perforation on which the shaft of one or various mills, blades or other similar cutting elements are installed, transversally located at its end, with any of these three elements.          The two elongated bodies and the mill shaft are able to rotate with independence of the others, in such manner that the operation of the apparatus is determined by the rotation of the mills and the relative turn of one of the bodies with respect to the other.

Abstract: ABSTRACT            TITLE:  Geothermal Turbine and Method of Using same A turbine and method of using the same to generate rotational power from a desired geothermal source from which a multi-phase pressurized and heated fluid is discharged, which fluid contains steam and particles of water, and may contain particles of solid material.  The turbine includes a rotor plate with a number of spaced discs secured to opposite sides thereof that are rotatably supported in a hous-ing, and the housing having two laterally spaced sets of circumferentially disposed nozzle bodies situated therein that are each adjustable to define a converg-ent section, a throat and a diverging section.  The nozzle bodies are 50 adjustable that streams of fluid at maximum velocity for a multi-phase fluid having particular characteristics as to heat, pressure and water droplet content discharge tangentially onto the two sets of spaced discs to flow through the spaces therebetween in spiral paths to discharge through openings in the centers thereof.  The fluid as it pur-sues a spiral path exerts a drag on the discs, with the fluid losing kinetic energy that is transferred to the discs, rotor plate and shaft to drive them as an integ-ral unit.  No substantial lateral force is exerted on seals in the turbine as the lateral force generated by one set of discs by pressurized fluid flowing through the spaces therebetween is cancelled out by a like and opposite force generated on the other set of discs by the fluid.

Abstract: LOCATOR FOR SOURCE OF ELECTROMAGNETIC     RADIATION HAVING UNKNOWN STRUCTURE OR ORIENTATION                           ABSTRACT Apparatus for determining the position of a source of electromagnetic radiation relative to a remote object is disclosed.  A multicomponent radiating means of unknown orientation is provided having components centered about the origin of the source.  A plurality of electrical signals are applied to the components of the multicomponent source to generate a plurality of electromagnetic fields.  The electro-magnetic fields are multiplexed and thus are distinguishable from one another.  A multicomponent receiving means is disposed on the remote object.  The multicomponent receiving means is provided with at least three orthogonal components for detecting and measuring components of the electromagnetic fields transmitted from the source.  The source and receiving means are adapted for operation at a separation distance sufficient to insure  that the far-field components of the electromagnetic fields received by the receiving means are substantially greater in magnitude than the near-field components of the fields received by the receiving means.  Analyzing means is associated with the receiver for converting the received components of the electromagnetic fields into source position relative to the remote object, and the relative orientation of the remote object without a priori knowledge of the orientation of the radiating means or the relative orientation of its components.  The analyzing means operates open-loop with respect to the source and determines source position and orientation with at least one ambiguous combination of orientation or position.

Abstract: DIFFERENTIALLY MODULATED AVALANCHE AREA   MAGNETICALLY SENSITIVE TRANSISTOR                         Abstract A new semiconductive device for sensing uniaxial magnetic fields is described. The sensor is essen-tially a dual collector lateral bipolar transisitor operated in the avalanche region.  Each of the collec-tors exhibits two space charge resistance effects.  One effect produces a negative resistance and the other produces a positive resistance.  When the two space charge resistances are carefully balanced, a net zero collector resistance is achieved.  A balanced condi-tion can be maintained for a broad range of collector currents.  A vertical VI property is thereby achieved. It has been found that the positive space charge resis-tance characteristic is inversely proportional to the ionization area and that the negative component is pro-portional to the area in the avalanche zone at each collector.  It has been found that a magnetic field can modulate the ionization areas at the collector junctions.  The area modulated results in modulation of the positive and negative space charge resistances at each collector and a resultant shift in the avalanche voltage occurs for each collector.  A differential out-put may be obtained since the modulation effect operates oppositely on each of the collector junction areas. This mechanism accounts for the linear and differential magnetoresistive behavior of the device.

Abstract: ABSTRACT OF THE DISCLOSURE        In magnetic sensing apparatus having a pair of directional magnetic field sensors longitudinally spaced apart in a containing tube, mechanical means is provided to compensate for misalignment in the sensor axes.  The compensating means takes the form of a non-magnetic member associated with one end of the tube for rotation about the tube axis and a screwed plug of easily magnetizable material contained in a diamet-rically extending threaded bore formed through the rotatable member.  Adjustments in the position of the magnetic body relative to the sensors may thus be made by screwing the body inwardly and outwardly of the bore to adjust the radial distance of the magnetic body from the axis of the tube and the orientation of the mag-netic body relative to the sensors may be adjusted by rotating the member in which it is contained relative to the tube.

Abstract: ABSTRACT OF THE DISCLOSURE A service integrated transmission system for transmitting, over a light transmission path, digital signals having a transmission band whose upper limit frequency corresponds to the maximum bit rate of the signals to be trans-mitted, the transmission being effected by simultaneously transmitting, over the transmission path, digital signals having a high bit rate only in an upper part of the transmission band and digital signals having a low bit rate only in a lower part of the transmission band.  The system includes a transmitter at one end of the path which separately multiplexes low bit rate signals into a narrowband signal and high bit rate signals into a broadband signal, combines those multiplexed signals, and modulates a light source with the combined signal.  A receiver at the other end of the path converts the modulated light signal into a demodulated electrical signal, separates the two multiplexed signals, and then demultiplexes each of the latter signals.

Abstract: METHOD AND APPARATUS FOR ESTABLISHING FRAME SYNCHRONIZATION     Abstract A synchronization technique in which the frame used for synchronization is different from that used for normal data communication and contains few if any bits other than those used to establish synchronization. At the beginning of data communication, the synchronization frame is stored in one of a pair of memories and this frame is read out of the memory onto a communication channel between the local and remote stations.  At the same time, the other memory is used to store the frame that is normally used for data communication. When synchronization is established between the local and remote stations, signal generation shifts from the first memory to the second; and the second memory immediately begins to produce the channel select and overhead signals needed for data communication.  Illustratively, the synchronization frame contains less than one hundred bits and in a preferred embodiment a total of forty-eight bits are used for synchronization.  As a result, synchroni-zation can be achieved much more quickly than in systems where three full data frames must be transmitted to achieve synchronization.  Moreover, since few, if any, of the bits present in the synchronization frame are customer-originated data bits or EIA-type control signals, false synchronization problems are avoided.
