Abstract: APPLICATION FOR                         LETTERS PATENT                               FOR                    PURIFICATION OF ACETIC ACID     ABSTRACT OF THE DISCLOSURE   A process is provided for purification and drying of acetic acid containing water and methyl iodide and hydrogen iodide as contaminants. The process comprises distillation in a two-zone system wherein the major part of the methyl iodide and hydrogen iodide and some water are removed as overhead and bottoms, respectively, from the first zone; a stream from the middle section of the first zone is introduced into a second zone into which there is also introduced a stream of methanol; and a stream of dry purified acid is recovered from the bottom of said second zone. The pro-cess provides both for the recovery of the iodine components and the metha-nol added for re-use in production of additional acetic acid by the reaction of methanol and/or methyl acetate with carbon monoxide in contact with a cata-lyst system formed on mixing of a rhodium or iridium component and an iodine component in the presence of carbon monoxide.

Abstract: REMOVAL OF METALS AND COKE DURING THERMAL, HYDROCRACKING OF HEAVY HYDROCARBON OILS     Abstract An improved process is described for thermally hydrocracking heavy hydrocarbon oil, e.g. bitumen.  According to the improvement, the hydrocracking is conducted in a cracking zone in the presence of small carbonaceous particles, e.g. coal, whereby metals and coke formed during the hydro-cracking reaction are deposited as a coating on the carbon-aceous particles and the coated particles are separated from the reaction system.  This process is useful in minimizing coke buildup in the cracking zone and in removing metals which tend to act as catalyst poisons in subsequent catalytic treatments of the oil.  The carbonaceous particles coated with coke, metals, and clay obtained can be used subsequently as fuel or subjected to gasification.

Abstract: ABSTRACT         An improved ball and socket joint usable in a steering system includes a stud having an enlarged head or ball portion and a socket having a cavity closed by an end cap, the socket cavity being adapted to receive the stud head therein.  An ex-pander, such as a belleville spring, is resiliently compressed between the end cap and the head.  The expander is the sole item interposed between the end cap and the head and serves the dual role of expander and supplemental seat for the head.  The ex-pander has a center opening, through which the head directly contacts the end cap and is pre-loaded by it.  As the assembly sustains wear, the expander comes into play to maintain loading on the head and to keep the head seated on the expander.  Pro-blems of tolerance stackup are avoided by preloading the end cap directly by the head, and utilizing the expander as the supple-mental seating means.  By initially compressing the expander to a fully flattened state, travel of the expander to full relaxa-tion is available to take up wear.

Abstract: ABSTRACT OF the DISCLOSURE          Dictation system including a dictation recording and transcribing unit which utilizes two discrete recording media for recording a first dictated message on one recording Medium at the same time that a previously recorded second message can be transcribed from the other recording medium.  Each of the two recording media,  which are  tape cassettes  in  the disclosed embodiment, is manipulated by separate and independent medium-handling devices within the dictation unit.  The dictation unit, which is intended to be located at a transcribing location and interconnected  with  one  or  more  remotely-located  dictate stations, includes the audio and control functions necessary for recording dictation and  for  transcribing previously-recorded dictation,  and  these  audio  and  control  functions  can  be interchanged  between  either  of  the  two  recording  media.          Transfer of the dictating and transcribing functions between the two recording media is accomplished by a single control, and safeguards are provided to prevent transcriber interference with the audio or control functions of the selected recording medium on which dictation is being currently recorded.   The system allows the dictator to record selected information signals along with the audio messages being recorded on a selected recording medium, and playback of previously-recorded information signals provides operational control determined by the  recording or transcribing  function which is  selected  for  the particular recording medium.

Abstract: ABSTRACT           A  shear liquid coupling of the temperature controlled type for driving the cooling fan of the radiator of an internal combustion engine.  The specific improvement resides in the use of a separate tube for returning drive shear liquid from a zone adjacent the drive rotor periphery to the shear liquid reservoir.  The use of such a separate tube obviates the need of drilling (or casting) a return shear liquid passage in the coupling.  Further, the use of such a separate tube permits operation in either direction of fan rotation.
