Abstract: ABSTRACT OF THE DISCLOSURE         A closed press section of a paper machine comprising a compact construction of at least four press rolls which are in mutual nip defining relationship forming at least three press nips between themselves and wherein a web runs in a closed draw   between the nips supported by a fabric, fabrics or a press roll face.  The press rolls include a suction roll and a smooth-faced press roll which together form a press nip provided with a single felt.  At least two additional press nips are formed in connection with the suction roll through which the web passes between two fabrics.  One of the fabrics in each of the first and second nips constitute a single upper fabric which also functions as a pick-up fabric by means of which the web is detached from the forming wire and passed through the first three of the press nips.  The press section may also in-clude a fourth press nip formed between a press roll and the smooth-faced press roll and through which a press felt also passes.

Abstract: ABSTRACT OF THE DISCLOSURE A Central Processing Unit (CPU) may be conveniently and selectively connected to a plurality of Cathode Ray Tube (CRT) terminals through the use of a connection station provided with adapter jacks for interconnecting the CPU and CRT operating cables.  The connection station includes an insulated panel in which the adapters are positioned and an enclosure in which the insulated panel may be retained.  The insulated adapter panel is preferably made out of a three layer phenolic board so that appropriate identification can be conventionally engraved on the board, and the insulated construction of the board prevents electrical interference between separately connected cables. The connection station permits remote connection of CRT terminals to the CPU without the necessity of running long cables back to the CPU which might be located at a considerable distance from the terminals.

Abstract: HUMAN GROWTH HORMONE PRODUCED BY RECOMBINANT DNA      IN MOUSE CELLS                 Abstract of the Disclosure A recombinant DNA composed of (1) bovine papilloma virus, (2) the promoter region of the mouse metallothionein I gene and (3) human growth hormone structural sequences ligated to the metallothionein pro-moter was constructed.  The recombinant was stably main-tained as an episome and directed production of human growth hormone when introduced into cultured mammalian cells.  Not only was the yield unexpectedly high, puri-fication was vastly simplified because the growth hor-mone was secreted into the tissue culture medium.  The process was suitable for spinner culture.  Additionally, recombinant DNA molecules composed of (1) bovine papil-loma virus and (2) the whole metallothionein I gene were utilized to render mouse cells resistant to toxic con-centrations of cadmium.  This combination was utilized as a selective marker to cotransfer other, non-select-able genes (such as human growth hormone) into mammalian cells.

Abstract: ABSTRACT          A no-flow vacuum control signal valve (10, 60) employing a single solenoid coil (34, 116) having a stationary ferromagnetic core (40, 68) and moveable permanent magnet armatures (46, 48, 100, 108) disposed adjacent the opposite ends of said core.  The permanent magnet armatures function as individual valve poppets for individually opening and closing a vacuum vent port (18, 96) and a vacuum source port (28, 88) communicating with a valving chamber (14, 78, 80).  A spring (50, 52, 104, 112) biases each poppet closed such that no fluid flows when the coil is not energized.  Upon pulsing with current of one polarity of the coil, the vent port remains closed and the vacuum source port is opened.          Upon pulsing of the coil with current of reverse polarity, the vent port is opened and the vacuum source port remainss closed.  The valving chamber has a third fluid signal port (32, 98) adopted for connection thereto for control signal output.

Abstract: ABSTRACT:     A rotation speed control apparatus for an internal combustion engine has a signal-responsive diaphragm, whose position is determined by a negative pressure signal and which controls the opening of a throttle valve.  If the signal is found to be abnormal, the diaphragm is rendered substantially inoperable, so that the throttle valve can be restored to a safe position, hence avoiding the risk of improper operation of the engine in the event of a malfunction of the diaphragm or other aspect of the pressure sensitive control system.

Title: Steady-state method for determining rich air/fuel  ratios
Inventor: HETRICK ROBERT E
IPC: G01N27/416
Filed: 1984-06-04
Granted: 1986-08-05
Abstract: ABSTRACT          A steady-state method for determining air to fuel ratios  rich  of  stoichiometry  includes  generation  of  a signal proportional to the concentrations of unreacted and partially reacted hydrocarbons.  Two electrochemical cells (11, 121) are spaced from one another and define between them  a  partially  enclosed  volume.   The  volume  is  in communication with the exhaust gases through an opening.          A first side of each of the two electrochemical cells is exposed  to  the  volume.   A  second  side  of  one  of  the electrochemical cells is exposed to the exhaust gases.  A second side of the other of the electrochemical cells is exposed to a reference atmosphere usually air.   External circuitry attached to the electrodes of both cells causes one electrochemical cell to pump oxygen into the partially enclosed  volume  from  the  reference  atmosphere.   This oxygen  reacts  with  unreacted  and  partially  reacted hydrocarbons within the volume which in turn causes an EMF to  be  generated  across  the  other  electrochemical  cell.          This EMF functions as the input to the external circuitry.          The circuitry pumps oxygen into the volume at rate which will  keep the  induced EMF fixed at an arbitrary value.          The  magnitude  of  the  steady-state  current  required  to accomplish this task is proportional to the concentrations of  unreacted  and  partially  reacted  hydrocarbons in  the exhaust gas and hence is inversely proportional to rich A/F ratio.

Abstract: ABSTRACT OF THE DISCLOSURE         A nozzle insert for an actuator head of a fluid dispenser includes a circular body having a central portion containing a discharge orifice, and an annular, conical flange extending radially outwardly from such central portion and being radially flexible relative thereto.  The insert is seated within a smooth, cylindrical head bore having a constant diameter, and engages a cylindrical probe on the head concentric to the bore.  An end wall of the flexible, conical flange faces outwardly of the bore and presents a sharp outer peripheral edge of a diameter slightly greater than the bore diameter.  And, the insert body is of a harder material than that of the actuator head, so that the conical flange defines a circular, self-locking pawl for positively locking the insert fully seated within the bore as the sharp peripheral edge penetrates into the bore wall.

Abstract: ABSTRACT         METHODS AND APPARATUS FOR FLANGING TUBULAR POLYMER ARTICLES     A method and apparatus are described for flanging a tubular article of a crystallisable thermoplastic polymer, particularly of a saturated linear polyester material such as polyethylene terephthalate, which has been heat-set to an elevated temperature, e.g. for producing bodies for processable food and beverage containers.  The open end (12) of the tubular body is applied to a flanging die (20) and heated to a flanging temperature above the glass transition temperature but below the heat-set temperature of the polymer.  The tubular body (10) and the die (20) are forcd together so that the softened end of the tubular article is forced to move outwards until it abuts against a stop ring (23) to form the flange (11).  The residual shrinkage in the polymer material helps it to take up the precise contours of the die and to form a well-defined flange.  The flanged end is then cooled, preferably to a temperature at least 20°C below the flanging temperature, before releasing the tubular body (10) from the die (20).
