Title: E. coli clone producing human pre-pro-urokinase - useful as thrombolytic agent
IPC: C12N9/72
Filed: 1984-10-16
Abstract: Prodn. of an E.coli clone which produces human preprourokinase (I) comprises first extracting and purifying total messenger RNA from human urokinase (II)-producing cells, and using the prod. for in vitro synthesis of complementary ds-DNA. - This is enriched in components at least large enough to code for (II), the prod. giving cohesive ends and inserted into a plasmid vector having complementary cohesive ends. The hybrid molecules are used to transform E. coli and the transformants contg. a DNA insert selected to provide a clone bank. - Clones contg. (II)-coding inserts are isolated (by testing with a (II)-specific probe), DNA extracted from them, inserted into plasmid vectors and recloned in E. coli. The clones having the DNA insert with the correct orientation and in the correct reading frame (as determined by restriction analysis and sequencing) are selected and ability to produce (I) confirmed by immunoassay. Also new is the complementary ds-DNA coding for (I) and E. coli clones contg. it.

Abstract: TITLE         AN ARRANGEMENT FOR ALTERNATELY ASSIGNING  A MARKER TO TWO TRANSLATOR ASSIGNERS OF AN AUTOMATIC COMMON CONTROL SWITCHING SYSTEM                     ABSTRACT An automatic common control switching system for local and/or toll tandem switching is disclosed wherein two translator assigners are used to recognize requests from the register/senders for one of the two translators of the system. The translator assigner connects the translator to the requesting register/sender, and upon receiving a "call for marker" signal from the translator, searches for an idle marker and assigns the latter to the translator.  The arrangement of the present invention detects the condition when only one marker is "on line", and then alternates the assignment of the marker between the two translator assigners.  For this purpose, each translator assigner in the system is provided with a detection circuit which monitors up to ten "marker busy" leads.  When only one marker is mon line", and providing that both translator assigners are functioning and "on line", the detection circuit of both of the translator assigners will start the sequence of alternating the assignment of the marker.  If the condition changes, i.e., more than one marker becomes available or one translator assigner is removed from service, the arrangement will release.  Thereafter, the assignment of the markers by the translator assigners will be accomplished via its normal sequence.

Abstract: Abstract of the Disclosure The invention relates to information transmission systems in which the band is spread at the transmitting end by means of a pseudo-noise sequence and is returned to normal at the receiving end by a similar sequence. In such systems it is essential that the frequency of the various oscillators used for the frequency conversions should be kept constant, or alternatively that the oscillators at the receiving end should be synchronised with the oscillators at the transmitting end.  In accordance with the present invention the oscillators at the transmitting end are synchronised by the clock fre-quency of the code generator and at the receiving end this clock frequency is extracted from the received signal and used to synchronise the oscillators in the various conversions.  One of the oscillators at the receiving end may be a Gunn oscillator which is synchronised by applying the output of the pulse generator to its synchronising input terminal through a frequency multiplier. In another arrangement the frequency of the Gunn oscillator is controlled by comparing the phase of the output with the phase of the output of a frequency multiplier supplied by the pulse generator.  In yet another arrangement the outputs of the Gunn oscillator and the frequency multiplier are mixed to form a difference signal which is compared in phase with the outputs of a low frequency reference oscillator.

Abstract: TIME BASE ERROR CORRECTOR            Abstract of the Disclosure A time base error corrector for correcting time base errors in recurrent information such as horizontal lines of a video signal by random selection of a delay line tap is disclosed.  Incoming recurrent information groups are con-verted into impulse trains, in which the information is carried on the leading edges of the impulses, which are passed asynchronously through a delay line of plural cascaded digital gates having propagation delays which provide known tapped increments of delay as well as providing regenera-tion of each impulse passing therethrough.  A digital counter is clocked at a rate corresponding to said delay increments and counts the time base error of a train as it counts down the taps of said line.  The total reached in counting the time base error determines the tap through which the impulse train is output from the delay line.  A restoration circuit then restores the original signal format to the corrected information group.
