Abstract: ABSTRACT OF THE DISCLOSURE          Styrene is removed from a recycle water stream of an ethylbenzene dehydrogenation process by liquid-liquid extrac tion to prevent polymer buildup on heat exchange tubes and to lower coke formation in boiler tubes.  The water stream is then fed into a heater to form steam for use within the reaction zone of the process.  The solvent used for the extraction is benzene or a normal paraffin and preferably is the overhead product of a benzene-toluene column which separates the products of the process.  The use of extraction lowers utility costs compared to stripping the recycle water stream.

Abstract: METHOD OF AND APPARATUS FOR MODIFYING A VIDEO SIGNAL TO PREVENT UNAUTHORIZED RECORDING AND REPRODUCTION THEREOF                    ABSTRACT OF THE DISCLOSURE               A method of and apparatus for modifying a video signal such that a video picture can be reproduced by a video display device in response to the modified video signal, but if the modi-fied video signal is transmitted and then recorded on a video signal recorder, a satisfactory video picture cannot be reproduced if that recorded modified video signal subsequently is played back.   A pulse whose amplitude is substantially equal to the peak white level of the video signal is inserted into respective horizontal blanking intervals of the video signal.  If this modified video signal is recorded on a conventional type of video signal recorder, the presence of the inserted pulse signal is detected by an auto-matic gain control (AGC) detector which, in turn, controls an AGC amplifier to substantially attenuate the modified video signal which then is recorded.

Abstract: MULTISTAGE EVAPORATOR APPARATUS AND METHOD OF                DISTILLING PETROLEUM               Abstract of the Disclosure A method and apparatus for separating a predetermined fraction from a crude oil includes preheating the crude oil to vaporize a portion, and feeding the two-phase crude to a first stage flash evaporator.  In the first stage evaporator, a vapor portion is separated from residual liquid and the residual liquid is used by means of heat exchange to preheat the crude oil.  The vapor fraction from the first stage evaporator has an approximate 90% ASTM distillation temperature about 50-60 F° higher than the first stage evaporator temperature.  The vapor fraction is condensed to form a condensate, and the condensate is conveyed to a stripping column for mass transfer with ascending vapors from a second stage boiling type evaporator.  The second stage evaporator is operated at a vaporization temperature approxi-mately equal to the 5% ASTM vaporization temperature of the predetermined petroleum fraction collected as liquid from the second stage evaporator.  vapors removed from the stripping column include a crude oil fraction having an ASTM flash tem-perature lower than the temperature of operation of the second stage, and crude oil volatile impurities.

Abstract: MACHINE FOR CLEANING A FABRIC WORKPIECE          Abstract of the Disclosure A machine for cleaning a fabric workpiece, e.g., a so-called spotting machine, operates with a suction nozzle having a screen on which the workpiece is supported.  The machine is portable, its casing containing a combination air blower and vacuum pump for generating the suction, and a water tank and pump assembly that provides water under controlled pressure and volume to an applicator tool whereby such water is applied to the workpiece.  The size of the screen is restricted to enhance the suction effect, and the pressure of water to the tool is restricted to prevent the splashing of water and dis-lodged stain particles by controlling the impact velocity.          These factors also ensure rapid withdrawl of the water by the suction nozzle and inhibit spreading of the water in the work-piece beyond the area to which it is applied.  This process is aided by the shape of the tool which has a flat face for engaging the workpiece and forming a shield around the orifice from which the water flows.  The pressure side of the air blower feeds a downwardly directed blowing nozzle situated just above the screen to enhance the drying effect, this air being heated by the blower motor.  Solvents other than water can also be used.

Abstract: BIMETAL LID LOCK     ABSTRACT OF THE DISCLOSURE         A safety interlock for a door of an automatic washing machine is disclosed.  The interlock securely latches the door during a spin cycle to prevent the operator of the machine from opening the door and catch-ing his hand in the rotating motor driven drum.  The inter-lock operates during operation of the motor and during a time delay period following de-energization of the motor to permit the drum to coast to a safe speed or to a stop.  In-eluded in the interlock is a switch member operable upon closure of the door to at least partially complete a circuit between the motor and a bimetallic element.  The remainder of the circuit is completed by a timer driven switch, and when the circuit is completed the bimetallic element is heated to move a latch on the frame of the appliance into locking engage-ment with a latch on the door.

Abstract: SYRINGE          ABSTRACT     Improved disposable syringe for taking arterial blood samples for blood gas testing and for administering epi-dural anaesthesia, wherein the syringe plunger has a compressible elastomeric tip member which has a peripheral annular wiper extending axially forwardly toward the syringe floor and radially outwardly at an acute angle to the longitudinal center line of the barrel and plunger to form an excellent seal with the inner surface of the syringe barrel while at the same time providing only a gentle pressure against such surface and hence an exceptionally low resistance to axial movement of the tip member and plunger.     The tip member and barrel floor are designed so that when the tip member is moved to its furthest point forwardly into engagement with the floor of the  syringe barrel, e.g., to eject air and excess liquid anti-coagulant, a sea]. is formed between the forward end of the tip member and the portion of the barrel floor immediately adjacent the needle opening in such floor upon initial contact of the tip member with such floor to prevent further flow of liquid out of such barrel and thereby trap a predetermined amount of the liquid in a space of predetermined volume remaining between the tip member and barrel floor.  The trapped liquid acts as a stop to prevent deformation and com-pression of the tip member against the barrel floor The plunger and tip member are also designed so that when the tip member initially engages the barrel floor as aforesaid to seal the needle opening and further forwardly directed axial force on the plunger is substantially restricted to that portion of the tip member which is behind the trapped liquid with a minimum of force being applied to the portion of the tip member located behind the needle opening whereby distortion of such tip member into such opening is minimized.  This, in combination with the aforesaid liquid stop minimizes the intake of air upon release of inward force on the plunger after it has been moved to its for-wardmost position against the barrel floor to eject air and excess anti-coagulant prior to taking a blood sample.
