Abstract: Abstract of the Disclosure Hydrogen fluoride is separated from the organic consti-tuents of a reaction mixture in the process for preparing 1-chloro-1,1-difluoroethane by the fluorination of methyl chloroform.  A portion of the reactor bottoms is removed and the HF and volatile organics are vaporized from the reactor bottoms or "tars". The HF and volatile organics are then combined with the product stream from the reactor, and the resulting combined stream is cooled such that two liquid phases are obtained.  One of the phases contains primarily HF and the other phase contains primarily 1-chloro-1,1-difluoro-ethane.

Abstract: ABSTRACT        A method and a multiple chamber apparatus for the continuous production of tandem, amor-phous, photovoltaic cells on substrate material, whereby, at least six amorphous semiconductor layers are continuously and sequentially deposited on the substrate material under steady state con-ditions.  The substrate material is driven from a supply core, through at least two triads of depo-sition chambers, to a take-up core.  Each amor-phous layer of each p-i-n-type cell is produced in one chamber of the triad of deposition chambers.          In the first chamber of each triad of chambers, a dopant gas mixture is introduced to deposit a first conductive semiconductor layer atop the sub-strate.  In the second chamber of each triad of chambers, a gas mixture is introduced to deposit an intrinsic layer atop the first layer.  And in the third chamber of each triad of chambers, a dopant gas mixture is introduced to deposit a sec-ond conductive layer, opposite in conductivity from the first conductive layer, atop the intrin-sic layer.  The multiple chamber apparatus is con-structed to substantially prevent (1) the dopant gases in the first or third chamber of each triad from contaminating the intrinsic gases in the sec-ond chamber of each triad of deposition chambers;          (2) and the dopant gases in the third chamber of a preceding triad of deposition chambers and the dopant gases in the first chamber of a succeeding triad of deposition chambers from cross-contamina-tion.  In the preferred embodiment, the intrinsic material is an amorphous silicon alloy which is doped by boron to form a p-type alloy and doped by phosphorous to form an n-type alloy.  The pre-ferred embodiment further contemplates the use of a glow discharge deposition process wherein vacuum pressure conditions, temperature levels, reaction gas mixtures, reaction gas flow rates, cathode power generation levels, substrate speed of trav-el, and substrate tension are precisely con-trolled.

Abstract: APPARATUS AND METHOD FOR IN SITU CONTROLLED HEAT PROCESSING OF HYDROCARBONACEOUS FORMATIONS          WITH A CONTROLLED PARAMETER LINE      ABSTRACT OF THE DISCLOSURE A system and method provide for preferential in situ heating of earth formations.  A plurality of elongated conductive electrodes are emplaced in earth formations in respective spaced rows bounding a particular volume of the earth formations and forming a transmission line, preferably a triplate line, extending in the direction of the electrodes with the particular volume of the earth formations providing a dielectric medium between respective rows of electrodes. Electromagnetic energy is supplied to the transmission line at a frequency at which the spacing between respective rows is less than about twice the skin depth at the frequency of the applied energy.  Reactance means are disposed along respective electrodes to provide predetermined effective transmission line characteristics to develop a predetermined heating pattern in the earth formations.  The reactance means may be reactances disposed discretely between sections of respective electrodes.  The reactance means may also be disposed between respective electrodes and the earth formation, as by a dielectric coating.  A heating pattern may be developed to heat hydrocarbon rich deposits preferentially.

Title: Method and apparatus for recording an information  signal
Inventor: ODAKA KENTARO
IPC: G11B20/18
Filed: 1983-12-20
Granted: 1986-11-18
Abstract: ABSTRACT OF THE DISCLOSURE           In recording an analog signal using two recording heads equally-spaced on a rotating drum, a magnetic tape is wrapped about a guide drum over an angular extent of 90°, so that there are recording periods when a head is tracing the tape and periods when no head is tracing the tape.  The analog signal to be recorded is converted to a pulse-code-modulated (PCM) digital signal in real-time periods which are longer than the recording periods during which a head traces the tape.  The PCM signals are time-base compressed to be slightly less than the rotary head contact interval and additional data such as parity data and cyclic redundancy check codes are added to the PCM signals to form a composite signal, which is written back into a memory system.  The time-base compressed composite signal is then read out repeatedly from the memory over one contact interval and supplied to the recording heads so that in the tracks formed by the heads on the tape the composite data appears more than once in each track, that is, slightly overlapped, thereby preventing dropouts and permitting the signal to be recorded on the tape by the head without accurately detecting the rotary phase of the recording head.
