Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a MHD system having an electrode assembly for connecting the system to a load, and duct means for passing a main plasma stream adjacent to the electrode assembly.  The electrode assembly includes a first elongated electrode having first and second ends located adjacent the plasma stream.  A second elongated electrode has a first end adjacent the first end of the first electrode and a second end adjacent the second end of the first electrode, the second electrode being spaced from the first electrode.  The system also includes a passage for passing a gas through the space between the first and second electrodes, and an exit for permitting the gas to exit between the first and second electrodes and into the duct.  An AC coil for striking an arc between the first and second electrodes ionizes the gas and electrically connects the electrode assembly to the plasma stream.  The arc is caused to move from place to place along the second elongated electrode between the first and second ends thereof.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus which may be referred to as a "pressuriza-tion head"  is described.  The apparatus is useful for impregnating the porosity surrounding a recess or "blind" hole in a porous material into which recess is inserted a metal connector (e.g. a recess in a graphite anode to receive a metallic electrical con-ductor).  The method of using the apparatus is also described.         The apparatus and the method of using same provide a com-plete and uniform impregnation of the material in the vicinity around the connecting hole, thus providing reduced contact corrosion.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for welding together a cover and a vessel formed of thermoplastic material comprises a pair of heating cheeks. Each heating cheek has two arms disposed in essentially L-shaped arrangement. The cheeks are adapted to be disposed between the cover and vessel to heat the respective edges thereof. The cheeks are mounted for movement in separate directions from between the cover and vessel without passing across the opening of the vessel. Therefore, the time required to remove the welding apparatus from between the cover and vessel is reduced, and there need be no concern for hitting elements projecting upwards from the vessel.

Abstract: A STRINGER FOR A SLIDE FASTENER    AND METHOD FOR MAKING SAME Abstract of the Disclosure The invention relates to a stringer for a slide fastener. The stringer comprises an elongated body having two leg portions connected by a bight portion to define a generally U-shaped configuration.  Transverse slots are disposed between closed ends of the bight portion to provide longitudinally spaced head members.          Further transverse slots provide longitudinally spaced legs on each side of the head members.  Longitudinally extending grooves are formed in the legs to receive stitches when the stringer is sewn onto a fabric.  The slots defining the head members are U-shaped with the open ends of the V being adjacent each other at the head members for flexibility when closing and opening the slide fastener.  The slots defining the legs are similarly V-shaped for flexibility.  The legs are close together at the free ends to provide a longitudinally extending aperture for receiving fabric.  The legs are relatively widely spaced apart adjacent the head members to provide a longitudinally extending recess for receiving head members of an associated stringer.  The stringer can be readily manufactured but is highly efficient in operation and has a relatively long, trouble-free life.

Abstract: JOHN C. MARTIN                 AUTOMATIC COFFEE MAKER WITH INLET WATER CONTROL MEANS IN RESPONSE TO  COLD WATER AND HOT WATER LEVELS                    Abstract of the Disclosure Cold water is supplied through an inlet water line from a source under pressure to a cold water basin from which it is siphoned to a hot water tank therebelow.          The hot water is siphoned out of the tank for brewing coffee extract.  A valve in the inlet water line is closed when the level of the cold water in the basin engages a probe or collar the elevation of which can be adjusted.          Under conditions of low water pressure the siphon to the tank may start before the shutoff level in the basin is reached.  Water may continue to flow without that level being reached.  The level of the hot water then rises above the siphon out level of the hot water siphon and engages a probe resulting in closure of the valve to prevent further flow through the hot water siphon and overflow of the tank.          Should the level of the water in the basin rise above the shutoff level, a float switch is opened to close the valve.

Abstract: Abstract of Disclosure An ink cartridge comprises a box containing a plastic bag or bladder which is manufactured, filled and sealed in the controlled environment of a factory.  As manufactured, the bladder has almost no chance of any substantial amount of air being entrapped therein. It has no openings, except for a small fill opening which is sealed immediately after the bladder is filled with ink.  The bladder has rounded contours to prevent entrapment of gas and foreign substances.  A plastic tube is welded to the outside of the bladder so that it may be penetrated and the bladder may be cleanly punctured within the tube in order to introduce the ink into the machine without simultaneously introducing air or other foreign matter into the ink.  A special follower arrangement feeds a piercing tool into the plastic tube without buckling or kinking it.

Abstract: TAB LAYOUT DISPLAY FOR A TYPEWRITER ABSTRACT       A panel of selectively-controllable indicator elements is associated with a viewable escapement scale on a typewriter and provides an indication of a set of operative tab stops stored in an electronic memory.  Escapement position codes extracted from an electronic tab storage drive a logic circuit that is so connected as to modify the state of individual panel elements at corresponding escapement scale positions to indicate a tab layout.  By providing, in a preferred implemen-tation, means for accessing the presently operative (selected) set of tab codes from a memory adapted to retain plural tab sets, the operator is enabled to assess the layout of each selection visually.  In such an implementation for a type-writer having two different selectable pitches, say pitches of 10 and 12 characters per inch, the panel elements are arranged to display the selected tab layout respective of pitch.
