Abstract: A CIRCUIT FOR ENCODING AN ASYNCHRONOUS BINARY    SIGNAL INTO A SYNCHRONOUS CODED SIGNAL            Abstract of the Disclosure Successive intervals of an asynchronous binary signal are examined for the occurrence of transition and each transition is encoded into a 2-bit binary code word. The occurrence of two transitions within a predetermined interval of time indicates that the asynchronous signal to distorted.  A first code word is generated in response to the first transition to indicate to remote decoding apparatus the occurrence of the first transition within the interval of actual occurrence.  A second code word is generated in response to the second transition to indicate to the remote decoding apparatus the occurrence of the second transition in an interval immediately subsequent to the interval in which the second transition actually occurred.  Polarity information is periodically transmitted to the decoding apparatus to ensure that the polarity of the asynchronous signal reproduced by the decoding apparatus is the same as the polarity of the original asynchronous signal.                             - i -

Abstract: TREATMENT OF COAL FOR THE PRODUCTION OF CLEAN     SOLID FUEL AND/OR LIQUID TURBINE FUEL     Abstract A two stage coal solubilization process is described comprising a relatively mild first stage operation followed by a second stage operation, the severity of which is controlled as a function of the final product desired -thereby providing at least a three product mode operation.          The first stage comprises the thermal solubilization of coal in a hydrogen donor material containing 10 - 50% by weight phenols at a temperature less than 800°F and a residence time restricting the formation of aromatics and the loss of hydrogen.  Insufficiently dissolved material and ash is thereafter separated, such as by filtration before processing in a second stage, generally more severe operation.  The severity of the second stage operation and conditions employed are selected to produce one of desulfurized coke, a solid product which upon heating is a flowable fluid or a hydrogenated product boiling in the boiling range of turbine fuel.

Abstract: ABSTRACT OF THE DISCLOSURE              Plasticized parisons of synthetic thermoplastic material are formed in an extrusion machine from where they are transferred to a station to be pneumatically converted in the cavity of an open-and-shut premold into hollow blanks which are larger than the parison but smaller than the desired shaped ar-ticle. During such pneumatic conversion the material of the pa-rison may be subjected to shock-like cooling concomitantly with conversion into the blanks, by appropriate cooling of the premold.          The hollow blanks are then transferred to an intermediate station where they are subjected to thermal tempering in two or more sepa-rate stages, in order to bring them to an optimum temperature con-dition for the subsequent biaxial stretching. After tempering, the tempered blanks are transferred to another station to be pneu-matically converted into respective shaped articles in the cavity of another open-and-shut mold and under biaxial stretching of their material.

Abstract: MEMORY AND APPARATUS AND METHOD FOR USING SAME               ABSTRACT OF THE DISCLOSURE          An addressable memory is supplied with pulse coded data at a first rate for writing such data into addressable locations in the memory; and stored data is read out from addressable locations at another rate different from the write-in rate.  One advantageous application of such a memory is for changing the time-axis parameter, such as the repetition rate, of data so as to effect time compression and/or expansion.          Control over the memory is achieved by generating write clock pulses and read clock pulses at different repetition rates.          Data, such as a pulse data bit, is written into an addressable location in the memory during the interval between successive write clock pulses.  A data pulse bit is read out of the memory during the interval between successive read clock pulses.  The read operation is delayed in the event that it coincides with a write operation.  The resultant asynchronous pulse bits which are read out of the memory are reclocked, or synchronized, with the read clock pulses so as to form a synchronous pulse train at the read clock pulse repetition rate.     -i-

Abstract: A B S T R A C T     This invention consists of a furnace which uses microwaves as the heating medium.  It consists primarily of two compartments, i.e. a cold air compartment which takes in recirculating air at room temperature and feeds into a hot air discharge compartment, by a blower contained therein; and a  hot air compartment in which the said air is heated by a series of back and forth bent steam pipes, and discharged for heating purposes.  The air heating compartment also contains the heating device which consists of a water supply tank which feeds water to a vaporizer which in turn feeds the vapor into a microwave equipped chamber, where it is changed to steam which flows in said back and forth bent pipes.  The steam condensate returns to the water supply tank.  A variation of the invention consists of a similar arrangement as des-cribed above but in which the vaporizer is replaced with a pipe made of a non-conducting material upon which the micro-waves act to heat the water therein and circulate it in the back and forth bent pipes.
