Abstract: Abstract of the Disclosure A method of marching solids of revolution by a rotary cutting tool whose effective portion is shaped as a solid of revolution set on a spindle and having a circular cutting lip, said solid of revolution being imparted rotation during the cutting process, wherein the tool axis is positioned in the plane parallel to the basic plane passing through the axis of machine centres and makes up an angle with the pro-jection of the axis of machine centres on said plane. The distance from the plane of the tool axis to said basic plane and said angle of setting the tool axis are estimated using the following relation:                       where H is the distance from the plane of the tool axis to the basic plane passing through the axis of machine centres; D is the diameter of the workpiece being machined; d a is the diameter of the circular cutting lip; .omega. is the central angle of setting the cool point with respect to the basic plane;     ?is the angle of setting the tool axis with respect to the projection of the axis of centres on the plane of the tool axis. The toolholder for carrying said method into effect comprises a body having an inclined top bearing surface and provided with longitudinal ways, a tool clamp mounted traversably along the body ways and fixably in a required position on the inclined body surface, and having a hole for the tool to ac-commodate. The hole in the tool clamp makes up an angle with the body ways and is parallel to the body base, whereas the angle of elevation of the inclined top bearing surface of the body is equal to a preset central angle of setting the tool point with respect to the basic plane passing through the axis of machine centres.      The present invention is instrumental in increasing vibration resistance of the cutting process and adding to the quality of workpieces machined.

Abstract: ABSTRACT OF THE DISCLOSURE            A  method of and apparatus for separating a lighter gas from a heavier gas in a gas mixture.  The method involves directing generally annular jets of a jet gas into the gas mixture, and extracting the lighter gas from the gas mixture through central zones of the generally annular jets.  The apparatus comprises a jet membrane separating a chamber for the gas mixture and a chamber for the gas enriched in the lighter gas, the jet membrane utilizing annular jet orifices communicating with the gas-mixture chamber and utilizing extraction tubes at the jet orifices and interconnecting the two chambers.          A jet gas delivered to the jet orifices is discharged there-through into the gas-mixture chamber, and the lighter gas of the mixture passes through the extraction tubes into the chamber for the gas enriched in the lighter gas.  By cascading a number of jet membrane stages of the foregoing nature, a very high degree of purity for the lighter gas may be achieved.

Abstract: METHODS OF PIPELINE CONSTRUCTION IN ARCTIC AND SUBARCTIC REGIONS AND APPARATUS FOR CARRYING OUT THE SAME Methods of pipeline construction in arctic and subarctic regions and apparatus for carrying out these methods are disclosed.  Summer-constructed fabrication yards are established at central locations along the pipeline right-of-way spaced at intervals of 100 to 150 miles each comprising a group of buildings utilized to fabricate instrument , and hermetically cap pipe sections, including quality control, x-ray, hydrostatic testing, external coating, final inspection, and rivet coating and weighting, along with facilities for moving pipe sections from place to place during fabrication, inspection, coating, etc.  After fabrication, the pipe sections are stored in a marshalling yard located near the end of the fabrication yard nearest the half-division in which it will be installed.  In winter each pipe section is towed to its place of installation over a working snow pad or snow road following the pipeline right-of-way, for instance, by a pair of large tow tractors operating in tandem.  Sensors or sensing instruments mounted on or in the pipe section during fabrication are cabled to indicating instruments in the lead tow tractor, to assure that while in transit the pipe section undergoes no bend less than its permissible roped radius of curvature. The forward end of the pipe section being towed is mounted on a nose sled bearing a compressor and air heater for the purpose of maintaining an elevated temperature inside the hermetically sealed pipe section.  To prevent "slideouts" or the like, portions of the pipe may be mounted on special "pipe sleds" provided with a lifting means which enable a sideboom tractor to raise a portion of the pipe section or impart a pull to assist in preventing sideslipping.  When a pipe section is being moved, a number of sideboom tractors accompany the pipe section, guiding respective portions of it in special roller cradles equipped with remotely controlled pipe-gripping means or brakes.

Abstract: TDMA INTERTRANSPONDER COMMUNICATION                 ABSTRACT OF THE DISCLOSURE    Groups of stations operate in TDMA mode relative to associated frequency-separated transponder segments of a satellite repeater.  Stations at radio signaling nodes in all groups key to a common frame timing reference.  The TDMA frame is partitioned repetitively into IN GROUP and CROSS GROUP intervals, each susceptible of containing multiple demand assignable burst time slots.  Each node may transmit TDMA bursts (of time compressed and time multiplexed information signals) in assigned slots in either interval (or both).  Such bursts are carried only on the transponder radio frequency associated with the respective group.  Station receivers are adaptive to switch local oscillator frequencies in synchronism with transitions between IN GROUP and CROSS GROUP periods, and thereby adaptive to receive signals from stations in both groups.          A frame reference signal carried on the transponder frequency associated with one of the groups is receivable by stations in the same group during IN GROUP mode reception and by stations in the other group during CROSS GROUP mode reception.  Con-sequently stations in both groups may key to that reference signal.  The transition (crossover time) from IN GROUP mode to CROSS GROUP mode can be varied in time position to efficiently accommodate demand within and between groups.

Title: Series notch filter and multicoupler utilizing same
Inventor: KAEGEBEIN DANIEL P
IPC: H01P1/202
Filed: 1978-10-30
Granted: 1982-03-09
Abstract: A cavity notch filter for series connection in a transmission line is disclosed which comprises a high Q cavity containing therein an inductively coupled L-C series circuit. When inserted in series in a transmission line, the notch filter acts as a high series impedance at, the resonant frequency of the cavity. At frequencies off resonance, the filter is characterized by low impedance so as to produce broad lateral pass bands. This notch filter finds utility in the construction of a multicoupler and enables reduced intermodulation interference and insertion losses compared to prior multicouplers constructed from conventional notch filters. Such a multicoupler comprises a number of signaling devices each connected to a different one of the notch filters which are connected one to another in series in a transmission line. Energy at all frequencies can then propagate down the line except the energy at the frequency of the respective signaling device. Energy of this frequency is blocked by the filter at a junction associated with the filter and is diverted to the respective signaling device.

Abstract: METHOD OF PRODUCING MAGNETRON ANODE          Abstract of the Disclosure In order to provide a method of producing magnetron anodes at a good mass-produceability, so-called straight type steel cylinder blanks, in which the inner peripheral surface is not tapered are used, and, at the same time, the step of quench-hardening of the steel cylinder blank is omitted.  After fitting a copper block to the inside of the straight type steel cylinder blank which has not been quenched, both members are compacted to each other.  Then, a press work is effected on the copper blank such that the steel cylinder blank and a back-up punch are forced to move relatively to each other, when a press-working shaping punch is forced into the copper block, thereby to form a copper anode.  In order to avoid the bursting of the steel cylinder blank, the press work on the copper block is effected at a temperature of 200 to 650°C.  In this way, magnetron anodes can be produced quickly and economically.

Abstract: ABSTRACT OF THE DISCLOSURE Blocks of digital words containing an error correcting word are time interleaved into time-interleaved blocks of words, each of which contains no more than one word from any one of the original blocks.  The time-interleaved blocks of words are converted to a bit-by-bit serial digital data stream which is time-base compressed to permit insertion therein of an error detecting code word and synchronizing signals.  The resulting serial data stream may be recorded on a VTR.  After reproduction, each time interleaved block is checked for errors and is then time de-interleaved to reconstruct the original blocks of digital words.  If one or more errors exist in words in a time-interleaved block, no more than a single word in any one of the time de-interleaved blocks contains an error.  Single-word errors in a reconstructed block are corrected using the error correcting word accompanying the reconstructed block.
