Abstract: Abstract of the Disclosure A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex copy mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding means which includes a coming wheel.  The combing wheel shingles the leading edge of the stack's top sheet to an open feed roller nip, to be sensed thereat by a pneumatic sensor.  Sensing of this leading edge causes the combing wheel to be lifted off the stack.  Subsequently, at a time de-termined by the copier's control logic, the drive nip closes to thereby feed the top sheet to the copier's paper registration gate, and then to its transfer station.  As soon as this sheet's trailing edge has cleared the pneumatic sensor, and the drive nip has opened, the next sheet is staged at the shingled position, in the open drive nip.

Abstract: A B S T R A C T     The present invention relates to a method of forming fractures and placing proppants therein, which comprises creating a foam having a down-well Mitchell quality of from about 0.53 to 0.99 and passing that foam down the well in admixture with a particulate proppant in an amount of up to three pounds of prop-pant per gallon of foam, then decreasing the gas volume in said foam, whereby the proppant carrying medium being passed down the well changes from a foam to a liquid.  The proppant concentration is decreased as the change occurs from foam to liquid so that the proppant material will not deposit out prematurely in the well.          Once liquid flow has been established, the proppant to fluid ratio is gradually increased and the fracture of the formation is contin-ued with liquid and proppant.  The liquid is capable of carrying an amount of proppant greater than that which could be carried by the foam, namely from four to ten pounds per U. S. gallon.

Abstract: ABSTRACT OF THE DISCLOSURE           Charging gases from each coking chamber in a battery of coke ovens are withdrawn through a closable ascension pipe into only a first gas main.  The gases liberated during carbon-ization of the coal charge in each oven chamber are withdrawn through a closable ascension pipe into only a second gas main throughout the remainder of the carbonization process.  The gases in each gas main are sprayed with flushing liquor.  Gases are continuously transferred from the second gas main through pipes into the first gas main to equalize the gas pressure within the gas mains.  Flushing liquor removed from the first gas main is processed to remove the tar content therefrom and to provide a clear flushing liquor which is used to spray charging gases within the first gas main.  Gases and flushing liquor removed from the second gas main undergo separation whereupon the gas phase is discharged for further processing and the liquid phase undergoes separation to remove solids and tars therefrom, thus providing clear flushing liquor for reuse to spray gases in the second gas main.

Abstract: ABSTRACT OF THE DISCLOSURE           Dialysis apparatus is arranged to enable convenient measuring of ultrafiltration rate from liquid, such as blood, that is to be dialyzed.  Dialyzate passageway through which the ultrafiltration flow rate can be readily measured as by introducing a gas bubble into the dialyzate and timing its movement through the passageway.  An air-injection attachment can be fitted to the dialyzer or to a dialyzate supply system, to inject the gas bubble for such measurement.  Bubble injection can also be effected in a flow rate measuring passageway downstream of the dialyzer.  Flow rates of dialyzate into and out of dialyzer can be compared to show ultrafiltration while dialyzing. Dialyzer can also have end caps with thickened closure walls for better ultrasonic welding to the dialyzer body, and the end caps can have vents that simplify testing of the seals between the caps and the dialysis membrane body.

Abstract: ABSTRACT         Blow-moulding apparatus for forming hollow bodies having a pair of mould halves closeable at a parting plane for the mould, and in which each half comprises a first mould section and a second mould section independently movable coaxially of one another.  The hollow body to be moulded has an external surface with a first greater transverse external dimension and a second lesser external dimension.          The first body dimension is defined by the first mould sections when in closed condition,and the lesser body dimension is defined by the second mould sections in closed condition.          In each of the mould halves, the first section guides the second section.    A line of separation between the first and second sections is arranged to be located in the region of smallest radius of curvature of the body.  The second mould section in each instance may include an island-like sharp-edged elevation with a rim which in the closed condition of the mould extends to the parting plane for defining an opening in the hollow body for hand-gripping of the body.

Abstract: PROGRAMMED DIGITAL SECONDARY CLOCK        Abstract of the Disclosure A programmed digital secondary clock which functions as a master clock, a sub-master clock or a slave clock.  When operating as a master clock, the programmed digital secondary clock maintains an updated real time count based on a 50 hz or 60 hz ac line or digital oscillator signal, displays the count, and serially transmits digital information representative of the updated real time count for use by a slave clock.  When operating as a sub-master clock, the programmed digital secondary clock receives an hourly or twice-a-day correction signal from a conventional master clock or a conventional electronic receiver, corrects the real time count, displays the corrected count, and serially transmits digital information representative of the cor-rected real time count for use by a slave clock.  Identical programmed digital secondary clocks can be connected in daisy chain.  The first clock can operate as a master clock or as a sub-master clock.  The following clocks can be operated as slave clocks.  When operating as a slave clock, the programmed digital secondary clock synchronously receives serial digital information representative of real time every second, maintains an updated real time count based on the received information, displays the count, and serially transmits digital infor-mation representative of the real time count for use by a following slave clock.  The programmed digital secondary clock can be operated as an elapsed timer or as an interval timer without interfering with the operation of the clock as a master, sub-master or slave clock.

Abstract: (Case No. 6977) ABSTRACT OF THE DISCLOSURE Insulated joint failure detectors are placed at each controlled signal location in the railroad interlocking to detect the condition of the insulated joints and also the passage of each truck of a train moving in either direction past that signal.  Contacts individually responsive to detector operation serially control the lockout of cab signal transmitter to inhibit the transmission of cab signal commands within the interlocking if an insulated joint fails or an unauthorized train overruns a controlled signal.  These detector contacts are individually bypassed by parallel circuit paths, controlled either by the corresponding home signal relay or cab signal control relays properly energized along an established route, in order to prevent lockout when the train is authorized to pass that signal location.
