Abstract: ABSTRACT OF THE DISCLOSURE           Basic asphaltenes are selectively removed from  asphaltene-containing  hydrocarbon  feeds  10  by contacting the feed with a transition metal oxide solid acid catalyst which selectively adsorbs the basic asphal-tenes 12 to produce an asphaltene reduced feed 14.   The catalyst will comprise a catalytic metal component select-ed from the group consisting essentially of oxides of (a)  tungsten, niobium, and mixtures thereof and (b) mix-tures of (a)  with tantalum, hafnium, chromium, titanium, zirconium and mixtures thereof, supported on an inorganic refractory oxide support such as alumina.  Asphalt-laden catalyst is separated from the feed 16, the asphaltenes adsorbed  thereon are cracked off 18 in the presence of steam 21 and the catalyst 22 is regenerated 24 and recycled 30 back to the adsorption zone 12.

Abstract: Method and Apparatus for Forging Sprocket Segments Abstract The invention discloses a process of forging a sprocket segment for a track-type vehicle under-carriage.  The forging process produces sprocket segments that conform to very restrictive tolerances without the necessity of additional machining or finishing.          The process includes heating a metal billet in an electric furnace, rough-shaping the billet, then forging the billet in a die to form a sprocket segment having a size and shape substantially equal to the desired finished shape of the segment.  The forged sprocket segment is trimmed and then placed in a coining die wherein at least two nonparallel surfaces are formed to a desired finished dimension.          The invention also includes an apparatus for forging a sprocket segment to a desired finished dimension.  The apparatus includes an upper die member, a lower die member, and a transversely-moveable die member.

Abstract: TITLE CALL-FOR-SERVICE AND CONTINUITY SENSOR CIRCUIT           A "call-for-service" and continuity sensor circuit for use with a trunk circuit of a digital PABX telephone system interfacing with a central office via ground start signaling providing for de-tection of a "call-for-service" signal to the PABX by the central office.  This circuit also provides high and closely matched tip to ground and ring to ground impedances for all trunk conditions in order to prevent excess loading of the trunk circuit.  This circuit provides a precise and stable threshold de-tection level necessary for accurate sensing of the trunk circuit conditions mentioned above despite parasitic leakage current, induced longitudinal power line voltages, and earth potentials sometimes found to exist on the line connecting the central office to the PABX.

Abstract: ABSTRACT         "Error-protected data transmission device and communica-tion network."     In a data transmission device which comprises at least one transmitting station and at least one re-ceiving station the same message is transmitted with an integer number of copies. This number may vary from one message to another. The number "n" is predetermined by the transmitting station as a function of inter alia the reliability of the network and the functional impor-tance of the message; thus, the same sequencing of the general events is presented to all stations without any acknowledge process, being required.

The  TDM  multiplex  is arranged in multiframes comprising N  frames O-(N-l).  Each  frame  comprises  P  byte  time  slots  iTO-iT(P-l)  for transmitting a packet per frame. The byte time slot iTO in each frame contains the frame alignment pattern of the frame, the byte time slot iTl contains the frame packet token byte, the byte time slots iT2-iTh contain the packet header,  the byte time slots iT(h+l)-iTx contain the useful data of the packet, and the byte time slot iT(x+l)-iT P-l) contain circuit type communication data.            The service and supervision messages between any of the units, on one hand, and the loop control unit, on the other hand, are exchanged in packet  mode.  The  digital  value of x may be changed by  the loop control unit which then transmits the value of x in packet mode to every operative unit.            The consecutive frames in a dialogue in packet mode between two units are  used  in  alternance  by  those  control  units  involved  in  the dialogue, the time interval iTx of each frame being allotted to the acknowledgment transmitted by one control unit to the other control unit relating to the packet the one  control unit received in the preceding frame.
