Abstract: LOW COST USER REPROGRAMMABLE           COMMUNICATION SYSTEM                 ABSTRACT          The present invention relates to the field of multi-channel communication networks, and particularly to mechanically reprogrammable local distribution of multiple incoming lines to multiple terminals.  The prior art includes patchcord systems having a central distribution panel and one or more remote or "satellite" distribution panels perma-nently wired to the central panel, requiring rearrangement of patchcords at more than one loca-tion.  The present invention provides reduced cost and complexity as compared to the prior art by permitting use of a single main distribution panel which terminates 211 incoming lines and to which all terminal connections are routed.  Channel identifiers and first connector means are provided on the distribution panel and separately identified cables having second connector means which is directly matable with any of the first connector means are routed from each terminal location to the panel so that any cable can be connected to any incoming line.

Abstract: ABRIDGEMENT          The invention relates to electrical systems in which a PTC device is used to protect a circuit against a thermal or electrical fault.  The systems of the invention comprise two circuits, one containing a PTC device and the other containing a resistor which is thermally coupled to the PTC device and which is heated when a fault condition occurs; this heating of the resistor converts the PTC device to the high resistance state and thus causes a desired change in the electrical condition of one or both circuits.  The invention can be used for the electrical circuitry of an electric blanket, as illus-trated in Figure 1.

Abstract: ABSTRACT Method for collection and separation of oil, gas and water from an offshore oil/gas well and a column for usage by the same.  The column comprises a vertically arranged tube with a lower end resting on the sea bed and an upper closed end from which gas may be discharged by gas outlet means. Oil/gas mixture flowing out of a well head in operation of the column will be retarded by an oil column in the tube, thereby releasing gas which is collected in the upper portion of the column.  Motion of the oil at the surface of the oil column will be very small, oil thereby flowing over an overflow rim into an overflow channel, from where oil is transferred to the sea surface by oil-outlet means.  The motion of the mixture may be additionally dampened by horizontal webs.  The column may be operated at sea depths more than 300 meters and in shallow water where the column may be constructed as part of a platform.

Abstract: Abstract of the Disclosure A metal test piece is disposed in a cell filled with a test solution.  The metal test piece is electri-cally charged instantaneously through a counter electrode so as to have a few millivolts polarization potential nt.  The charge consumed by the corrosion reaction of the test piece is measured by a potential recorder in the form of a variation of the polarization potential nt with respect to time t.  The measured (nt-t) relation is analyzed to obtain the polarization resistance Rp of the metal test piece.  After the poten-tial of the metal test piece returns to its natural potential Ecorr, the test piece is charged again until its polarization potential nt rises to 50 millivolts or more, and the (nt-t) relation is measured in the same way as mentioned above. Based on this relation, the Tafel slop .beta.a of the anodic reaction is obtained.  After the potential of the metal test piece has returned to its natural potential Ecorr, the test piece is so charged fro the third time as to have its polarization potential nt lowered to -50 millivolts or less, and the (nt-t) relation is measured.  This relation is analyzed to obtain the Tafel slope .beta.c of the cathodic reaction.          Based on the polarization resistance Rp, Tafel slopes .beta.a and .beta.c, the corrosion current density Icorr is obtained, from which the density corrosion rate V is calculated.

Abstract: ABSTRACT OF THE DISCLOSURE             Web breaks occurring in the drying section of fast-running paper machines are among the most important factors limi-ting the increasing of paper machine speeds.  With a view to avoiding these drawbacks a paper-machine multiple cylinder dryer is disclosed which comprises a number of drying cylinders , in conjunction with which a drying fabric is used which supports the web from one cylinder to the other in closed conduction.          Furthermore, one or more supporting fabrics are used in the dryer, which support the web on the cylinders.  The runs of the web supported by the drying fabric, the free surfaces of the drying cylinders and the runs of the supporting fabric confine elongated pockets associated with the cylinders.  With a view to elimi-nating the drawbacks mentioned, the pockets in the direction of travel of the web, at least in the initial part of the dryer are maintained at a pressure higher than the ambient atmospheric pressure.  The running of the web can be substantially stabilized by this expedient   For the purpose of producing the over-pressure, both ends of the pockets can be totally or partly closed with special closing members.

Abstract: RANDOM DROPLET LIQUID JET APPARATUS AND PROCESS     ABSTRACT          Fluid or liquid jet marking apparatus and process wherein the treating fluid or liquid (10) is in the form of ink, dyestuff or other printing, marking or coloring medium, is delivered under pressure to an array of jet orifices (14) from which the medium issues continuously as streams (16) that break randomly into discrete droplets in flight.  The moving random droplets are selectively charged as they pass through a selectively energizable electrostatic field (18).  The paths of charged droplets are controlled by a deflection means (20) which establishes a second electrostatic field through which the droplets pass.  Depending on whether the droplets are charged, they are either caught by a collector (22), or impinge on a receiving substrate such as a textile, paper or any other desired medium, product or substance.        In the apparatus, the streams (16) break up randomly into droplets.  Since the apparatus is not provided with a separate stimulator, vibrator or perturbation device, the orifice plate can have virtually an unlimited cross-machine length.  It has been found that by controlling certain equipment parameters, such random droplet breakup can occur within a narrow distribution around a mean droplet size to produce results very much the same as with perturbed systems that use separate, regularly cyclical varicosity inducing means, and in many cases are superior to perturbed systems in a large variety of applications as the length of the orifice plate is not limited in size.  The undesirable effects of droplet to droplet size and spacing variation become narrowed with increased pressure on the fluid or liquid supply and decreased diameter of the jet orifices.
