Title: Inert removal from chlorinated hydrocarbon production  system
Inventor: HUANG CHIUNG-YUAN
IPC: C07C67/00
Filed: 1976-01-16
Granted: 1980-07-22
Abstract: A B S T R A C T        In the production of chlorinated hydrocarbons, a gas stream containing unreacted hydrocarbon, chlorinated hydro-carbon, carbon dioxide and inerts, such as, carbon monoxide and/or nitrogen, is contacted with a chlorinated hydrocarbon absorption oil to separate hydrocarbon, chlorinated hydro-carbon and carbon dioxide from inerts, The rich absorption solution is introduced into a stripper wherein chlorinated hydrocarbons are recovered as a sidestream, absorption solution as a bottoms and a hydrocarbon-carbon dioxide stream, containing a reduced amount of chlorinated hydrocarbons, as overhead. The overhead is introduced into a further absorption column, primarily designed to recover chlorinated hydrocarbons in the absorption solution, with a hydrocarbon overhead being withdrawn therefrom which is rich in carbon dioxide and is essentially free of low boiling chlorinated hydrocarbon, to thereby faeilitate subsequent separation of carbon dioxide. The process is particularly applicable to the production of chlorinated methanes or vinyl chloride.              -i-

Abstract: OPTICAL COMMUNICATION SYSTEM WITH BIPOLAR            INPUT SIGNAL            Abstract of the Disclosure A bipolar electrical signal of the type transmitted in the T1 digital transmission system is converted into an optical binary signal having pulses and spaces by translating each positive digital "1" in the bipolar signal into two digital pulses, each negative digital "1" in the bipolar signal into two spaces, and the digital "0" in the binary signal into an optical pulse followed by a space.  The nonpermitted code of space followed by an optical pulse is utilized at the receiving location for instantaneous framing.  As a result of this particular code conversion, the balanced property of the bipolar input signal is maintained in the optical signal thereby preventing an offset bias from developing at the receiving location in the photodetector. In addition, the bipolar information is maintained in transmission, thus making the optical system "transparent" to bipolar signals.

Abstract: ABSTRACT      Lengths of polymer-coated tubing are continuously produced from steel strip by roll-forming and welding at a fast rate of speed.  The welded tubing is sized, cleaned and heated to raise its temperature to that desired for applying a polymeric coating.  After coating, the tubing is heated to a desired baking temperature and then cooled.  The tubing is unsupported from a location upstream of the coating station until cooled.  Elongated endless belts grip the tubing over a longitudinal distance of at least about two feet and pull the tubing in a controlled manner to maintain the tubing in precise spatial location throughout its heating, coating and baking.

Abstract: 46,671 AUTOMATIC TRANSFER CONTROL DEVICE       AND FREQUENCY MONITOR     ABSTRACT  OF THE DISCLOSURE          An atuomatic transfer control device for generating signals to cause associated circuit interrup-ters to selectively energize an electrical distribution system from either of a pair of electrical power sources.  The device includes an over- and under-frequency monitoring circuit to determine if the power source frequency is within preset limits.  The frequency monitoring circuit includes a zero-crossing detector which activates a clock oscillator, the output pulses of which are accumulated by a counter for one half cycle.          The number of pulses occurring during the half cycle is compared with a limit value stored in a read-only memory.  An alarm signal is activated if the number of pulses accumulated is out of limits.  The address inputs of the read-only memory are connected to the alarm signal generator and to a flip-flop toggled by the zero-crossing detector so that any of four limit values are selectively accessed for input to the comparator:  high limit, low limit, return-to-normal after high alarm, and return-to-normal after low alarm.  A strobe circuit is provided to only momentarily energize the read-only memory, thereby reducing power consumption.

Abstract: Abstract of the Disclosure When combining two video signals on a television screen it has been common practice to extract from the two video signals only those portions required and display those portions together on the screen.  A problem arises if a desired portion of one video signal coincides with a desired portion of the other video signal because, in that case, only one of the two portions can be displayed.  The present invention permits this problem to be overcome without changing the camera position or angle or moving the subjects or scenes being shot.  One of the video signals is operated on in a special effect device where it is divided into portions shifted apart from each other according to an external control signal.  The actual configuration and spacing of the portions can be varied by varying the control signal to en-sure that the various portions of the one video signal do not coincide with desired portions of the other video signal.

Abstract: Abstract of the Disclosure Symmetrical integrated transistors and drive circuitry provide low loss bilateral analog crosspoints for a switching matrix.  Each crosspoint comprises a high performance PNP lateral transmission switching transistor and an associated NPN vertical drive transistor formed over a common n-type buried tub in a p-type substrate. Individual crosspoints, including the transmission tran-sistor and the drive circuitry, are isolated by means of frame shaped p-type isolation regions lying outside the buried tub.  The collector of the NPN drive transistor and the base of the PNP transmission transistor are ohmically connected by means of the buried tub.  Accord-ingly, although the transmission transistor and the drive transistor are merged in a single isolation region, current drive to the PNP transistor is by means of the NPN trans-istor as a functionally independent device.  The lateral PNP transistor comprises stripe shaped emitter and collector electrodes which are formed in a single step with the isolation region and the electrodes are of equal doping, size, and shape.  Pluralities of such emitters and collec-tors which are respectively interconnected by surface metallizations may be utilized to increase the efficiency and the current carrying capacity of the transmission transistor.
