Abstract: Abstract of the Disclosure A multiprocessor system intercouples the processors with an active logic network having a plurality of priority determining nodes.  Messages applied concurrently to the network in groups are sorted, using the data content of the messages, to a single or common priority message which is distributed to all the processors with a predetermined total network delay time.          Losing messages are again retried concurrently in groups at a later time.  Message routing is determined by local acceptance or rejection of messages at the processors, based upon destination data in the messages.  All messages occupy places in a coherent priority scheme and are transferred in contending groups with prioritization on the network.  Using data, status, control and response messages, and different multiprocessor modes, the system is particularly suited for configuration in a relational data base machine having capability for maintaining an extended data base and handling complex queries.

Title: System and method for dynamic background subtraction
Inventor: BROOKS SAMUEL H
IPC: A61B6/00
Filed: 1982-06-09
Granted: 1985-04-09
Abstract: FOR: SYSTEM AND METHOD FOR DYNAMIC BACKGROUND SUBTRACTION An image acquisition system and method for generating a subtracted image motion picture as an imaging device moves relative to a subject includes an imaging device for first generating a sequence of first image frames as the imaging device moves along an imaging path under operator control and later generating a sequence of second image frames as the imaging device automatically moves along the same imaging path under processor control. Motion along the imaging path can be duplicated by sensing and storing information indicative of the position of the imaging device relative to the subject as a function of time and later commanding servo motors connected to the imaging device using that position information. Each frame in the first and second sequence of frames has position information stored therewith identifying the location along the imaging path at which each frame was generated. The first and second sequence of frames may then be aligned using the position information and subtracted on a frame-by-frame basis to obtain a subtraction image motion picture essentially free of background interference to detect change over time. The first and second motion pictures may be made at different points of time under similar circumstances either with or without the use of a contract medium, and subtracted to obtain a difference picture to highlight changes over time.

Abstract: ABSTRACT            A PROCESS FOR THE PREPARATION OF HYDROCARBONS      Hydrocarbons and especially as gasoline are prepared by the catalytic conversion in two subsequent reactors of a synthesis gas containing hydrogen and carbon oxides and having a mole ratio CO/H2 above 1 and when the conversion commences a mole ratio  CO/CO2 of 5 to 20. In the first reactor, which is preferably a cooled reactor, the synthesis gas is converted into a methane-containing first intermediate and this at least partly further into a second intermediate containing dimethyl ether, at 5-100 bar and 150-400°C, in the presence of catalyst(s) catalyzing the reactions (1) CO + 2H2?CH3OH, (2) 2CH3OH?CH3OCH3  +  H2O and (3) CO  +  H2O?CO2  +  H2, the effluent from this reactor is combined with a recycle stream containing low boiling components of the effluent from the second reactor, and then passed to the second reactor, which is adiabatic, where the conversion of the second intermediate is carried out at substantially the same pressure as in the first reactor and 150-600°C in the presence of a catalyst, preferably a zeolite catalyst, converting said intermediate partly into hydrocarbons, preferably hydrocarbons that are liquid at NTP conditions. The effluent from the second reactor is passed to a separator and separated into a number of streams, viz. (a) a stream mainly containing water and being conducted away; (b) a purge stream of hydrogen, carbon oxides, lower hydrocarbons and inert gases, also being conducted away; (c) a first recycle stream of same composition as the purge stream  (b) and being recycled to be mixed with fresh synthesis gas and steam so as to form a feed for the first reactor, said first recycle stream and optionally the fresh synthesis gas being optionally subjected to a wash to remove part of CO2 therefrom so as to adjust the CO/CO2 ratio; (d) a second recycle stream as mentioned above to mix with the effluent from the first reactor; and at least one product stream containing the desired hydrocarbons.
