Abstract: IDLE TIME SLOT SEIZURE AND TRANSMISSION FACILITIES FOR LOOP COMMUNICATION SYSTEM     Abstract of the Disclosure A time division multiplex loop communication system for voice and data is disclosed with multiaccess time slot seizure and data transmission capability from all station nodes without changing the idle, nonreserved, status of the seized time slot.  Station node apparatus sends bursty data packets from a node when a time slot is not busy serving a longer duration voice telephone call. The apparatus eliminates the need for inefficient time slot request, acknowledgment and reservation procedures which require several TDM frames to complete and which are typically longer in duration than the bursty data packet to be transmitted.  All stations have access to all time slots for bursty data transmission under control of loop interface circuitry which statistically ensures the successful data transmission from all sending nodes.  The interface circuitry includes input and output buffers, slot and bit identification circuitry, bit stream retard circuitry, output selector circuitry, bypass decision circuitry, and data and voice insertion control circuitry comprising a slot decision control circuit, a seizure timing circuit and an acknowledgement check circuit.

Abstract: MITIGATION OF RADIO FREQUENCY ELECTRIC FIELD   PEAKING IN CONTROLLED HEAT PROCESSING OF   HYDROCARBONACEOUS FORMATIONS IN SITU   ABSTRACT        The effects of radio frequency electric field peaking in the earth formations surrounding a conductor excited by radio frequency energy in the controlled in situ heat processing of hydrocarbonaceous earth formations are mitigated by providing an inert buffer region around the conductor to which radio frequency electromagnetic energy is supplied to produce an electric field within the earth formations.  A portion of the earth formations is removed to accommodate insertion of the conductor at a desired location in the earth formations and to provide a buffer region between the conductor and the surrounding earth formations.  The conductor is supported at the desired location in spaced relationship to the surrounding earth formations, the buffer region encompassing the principal region of the electric field enhancement region around the conductor where the probability of breakdown in the earth formations over the period of application of the radio frequency energy would be above a tolerable level,  The buffer region is filled with dielectric materal having an electric field breakdown level greater than that of the surrounding earth formation medium such that the probability of breakdown in the buffer region over the period of application of the radio frequency energy is tolerable.  Preferably the filler medium has a power dissipation characteristic less than that of the surrounding earth formations.

Abstract: ANTENNA ROTATOR CONTROLLER            Abstract of the Disclosure Controller for an antenna rotator having a rotatable member on which is mounted an antenna to be rotated to various headings.  Switching circuitry selectively energizes a motor in the rotator to rotate the member in either of two, opposite directions.  Antenna headings are user selectable and pre-programmable, the controller including control circuitry for accepting pre-programmed headings entered from a keyboard storing the pre-programmed headings and retrieving headings. Users can select a pre-programmed heading or enter a new head-ing via the keyboard, the control circuitry controlling the motor switching circuitry to rotate the antenna to the select-ed heading.  Circuitry is also provided to energize a brake solenoid in the rotator to, in the absence of jamming or bind-ing, release the brake.  To rotate the member to a new head-ing, the control circuitry energizes the brake solenoid and alternately rotates the member small amounts in the two oppo-site directions to effect the release of the brake from any jammed or bound condition.  Selected headings and current headings are acoustically announced to the user over a speaker.

Abstract: MICROWAVE MOISTURE MEASUREMENT OF MOVING PARTICULATE  LAYER AFTER THICKNESS LEVELING     ABSTRACT OF DISCLOSURE     Apparatus is disclosed for measuring the moisture content of a moving layer of particulate material carried on a conveyor by transmitting a beam of microwave radiation through such layer.  A portion of such microwave beam is absorbed by the water in the particles and the unabsorbed portion is detected to determine the moisture content.  A layer leveling means including a rotating endless flexible leveling belt engaged by a pressure roller, contacts the top surface of the particulate layer to level the thickness of such layer upstream of the measuring position, thereby enabling more accurate measurement of its moisture content.  The height of the pressure roller above the conveyor is adjusted in response to changes in the thickness of the layer being measured.          A beam of penetrating radiation of a type diverse from microwaves, such as gamma radiation, which is absorbed by the total mass of the particulate material may also be employed for determining such mass so that the precent of moisture content can be calculated.  The thickness of the measured portion of the layer is determined by measuring the height of the pressure roller above the conveyor.          This height measurement may be made by an ultrasonic distance gauge, or by a electro-mechanical transducer moved with the height adjustment of the pressure roller.

Abstract: MIRROR MECHANISM FOR FUSION-SPLICING APPARATUS            Abstract of the Disclosure Apparatus for fusion-splicing two optical fibers, comprises a pair of supports each arranged to support one of said fibers in end-to-end relationship to the other fiber such that the juxtaposed ends of said fibers are juxtaposed in a predetermined region between said supports.  Electrode means for generating a spark discharge in said region for heating the end portions of fibers inserted therein, conveniently comprises a pair of electrodes disposed one each side of the alignment axis for the fibers.          Alignment of the fibers is monitored by viewing them with the aid of mirror means having a mirror surface inclined relative to a common plane of the alignment axis for the fibers and a predetermined viewing direction.  The mirror surface provides an image corresponding to a view of said fibers taken in a direction transverse to said viewing direction.  Spattering of the mirror during the heating process is avoided by displacing said mirror means in said viewing direction between a first position close to said alignment axis, wherein said mirror means can provide said image, and a second position further away from said alignment and the viewpoint.          Because the mirror is not displaced sideways, i.e. along the alignment axis, the fibers can be gripped very close to their ends to minimize flexing which can arise due to surface tension effects and cause realignment of the fibers during the fusion step.                           -(i)-

Abstract: ABSTRACT      There is disclosed an apparatus and method for con-juncting and separating density differentiated components from a moving carrier liquid.  The liquid to be treated flows through zigzagging separation passages comprising cells extending through a three-dimensional lattice con-structed of interconnected triangle pairs each defining a cell there between.  The shear of the liquid is increased to induce component particle conjunctions by flowing the liquid through a narrow cell passage opening.  The shear is then decreased as the liquid flows through the ever-widening cell to a wide cell passage opening to induce separation of the component particles.  Heavy and light separated component particles are channeled to a lower side and upper side, respectively, of the lattice along zigzagging channels.
