Abstract: ABSTRACT        The present invention relates to impovements in a commercial apparatus for non-tubular cracking of heavy hydrocarbon feeds for the purposes of producing ethylene and other valuable olefin products as well as chemical grade synthesis gas. The prior art cracking apparatuses fail to employ a practical and economical process for producing high yields of ethylene by the diacritic cracking of heavy hydrocarbon feed stocks at elevated pressures in such a way that the reactor and subsequent heat exchange equipment will not adversely affected by severe coking. The apparatus of the present invention includes a combustor for burning a fuel with oxygen to provide the combustion products for the reactor. The combustor is water cooled and includes gas filming to avoid coking in the combustor by preventing impingement of the fuel and combustion products on the combustor walls. The reactor is of reduced cross-section, also preferably utilizing gas filming. Feed stock injectors are provided adjacent to reactor inlet for injecting the feed stock at a velocity sufficient to transverse approximately 60 to 70 percent of the reactor diameter. This encourages rapid heating of the injected feed stock while avoiding feed stock impingement of the reactor wall. Adjacent the outlet end of the reactor is quench section to reduce the stream temperature below that at which further cracking will take place, with the quench injectors also being gas filmed to avoid coking thereof.

Abstract: ABSTRACT OF THE DISCLOSURE         A printing system and printing method are provided having an electric circuit supplying an output potential to assist the transfer of ink to a printable substrate.  The printing apparatus includes (a) a printing cylinder; (b) an impression roller positioned with respect to the printing cylinder; (c) an ink supply positioned to provide ink to the printing cylinder; (d) a web having one surface contacting the printing cylinder and the other surface contacting the impression roller and passing therebetween during operation of the apparatus; (e) means for moving the web through the apparatus; (f) means for inducing an electrostatic charge onto the web so that the surface contacting the printing cylinder has a given polarity which the ink supply has opposite polarity; (g) a high voltage power supply connected to supply a high voltage to the charge-inducing means to produce an electrostatic field only between the web and the printing cylinder for aiding the transfer of ink from the printing cylinder to the web, wherein the charge-inducing means is positioned so as to induce the charge onto the web prior to entry of the web into the nip between the printing cylinder and the impression roller; (h) a conductive roller positioned to roll in contact with the impression roller; and (i) a low voltage power supply providing a voltage ranging from 1 to 10 per-cent of the high voltage potential provided by the high voltage power supply, the low voltage power supply being connected to the conductive roller to supply a low voltage thereto of a polarity the same as the polarity of the high voltage connected to the charge inducing means.     Thus, the potential is applied to the substrate prior to entry of the substrate into the nip of the printing apparatus.  The potential may be applied by a roller, or by a plate, a knife-edge, a series of points or a corona discharge.  The substrate may be neutralised before and after charging and printing.  Plates may be provided to pre-charge the substrate prior to application of potential.  The impression roller can carry a lower potential than that imposed on the substrate, or may have no potential imposed thereon.  This method and system provides an improvement on the indrodution of an electrostatic field into the impression roller since the problem of clean up shut-down in the event that the web tears or has holes therein is obviated.

Abstract: ABSTRACT       Hydraulic control apparatus serves to operate roof support props of a mineral mining installation.  An automatic setting arrangement ensures the props are set against the roof with a high and uniform force by connecting the prop pressure chambers to a pressure fluid feed line once  a threshold pressure is exceeded.  Once the desired setting pressure is reached the setting arrangement then isolates the pressure chambers from the pressure line and the props are protected from excess pressure by pressure-relief valves.  The setting pressure is approximately the same as the response pressure of the relief valves and the latter valves are designed to pass a maximal throughflow quantity of pressure fluid which is approximately the same as that passing through control valve devices operated manually to cause the props to extend or retract.

Abstract: METHOD AND APPARATUS FOR SENSING CURRENT        IN HIGH VOLTAGE CONDUCTORS                        ABSTRACT     A method and apparatus for sensing current in high voltage conductors.  Alternating current carried in a high voltage conductor is sensed by a toroidal coil to produce a first low level signal representative of the time derivative of the alternat-ing current signal. Transmitter means operating at or near the potential of the conductor and remote from electrical ground receives the low level signal and in response produces a series of modulated pulses wherein at least one of the pulse parameters is a function of the amplitude of the high voltage alternating current signal.  Advantageously, the transmitter may be powered by a power supply deriving power from the high voltage conductor.  The pulses produced by the trans-mitter may be transmitted to a receiver operating at or near ground potential, which receiver then converts the pulses into a second low level signal representa-tive of the high voltage alternating current signal.

Abstract: ABSTRACT OF THE DISCLOSURE:       A non-inverting liquid dispenser is taught, for use with a liquid-containing vessel.  The container (vessel) may be flexible, partially flexible, or rigid, but usually the container is flexible.  At all times, the dispenser remains at the bottom of the container, rather than the requirement to invert the container to dispense liquid contained therein.  The dispenser has two diaphragm operating valves, one of which is biased towards an opening through which liquid will flow, when the interior of the liquid-containing vessel is at a positive pressure differential with respect to the ambient.  When the pressure is relieved --i.e., a negative pressure differential with respect to the atmosphere develops within the container -- the other diaphragm valve opens, permitting the container to be vented.  The only moving parts are, in fact, the diaphragms.  In one embodiment, the diaphragms are side-to-side, and each is biased over a stub which is directed against its central portion; in a second embodiment, the diaphragms are superimposed one above the other, but each opens in a direction towards the other diaphragm; and in two further embodiments, the diaphragms are also above each other, but each opens in a direction away from the other diaphragm.  It is possible to provide an antiseptic, non-inverting liquid dispenser where the liquid is contained within a collapsible bag in the dispenser, with the dispensing operation being as previously stated upon causing a positive pressure differential within the vessel, with respect to the ambient pressure.  The dispenser may be connected to a source of pressurized air, by which a dispensing operation can be initiated and controlled by selectively coupling the interior of the vessel to the pressure source.
