Abstract: ABSTRACT OF THE DISCLOSURE A system for diagnosing and controlling operation of a plurality of modems, some located at a central site and others at various remote sites.  A processor located at the central site selectively addresses microprocessor test and control units at each modem over a secondary channel.  The microprocessor test and control units respond to commands to configure and perform various modem tests, operate autonomously to monitor various alarm con-ditions, and format status reports and alarm maydays for trans-mission back to the central processor.  The system is capable of performing a wide variety of testing, monitoring and network control functions for a very large network of modems.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved valve system for obtaining access to a container of fluid.  In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container.  A sealing mechanism is provided to secure the valve assembly in sealed relationship with the keg neck and to allow access to the fluid contained by actuation of the valves.  More specifically, the valve neck has a groove in its inner surface to receive a resilient retainer ring which maintains the valve assembly in place.          In addition, a safety feature is provided to prevent inadvertent expulsion of the valve assembly should the retainer ring be dislodged while the keg is pressurized.  A siphon tube extends from the valve assembly to a position adjacent the bottom of the keg when the valve is secured within the keg neck.  The bottom portion of the tube is configured to enhance the flow of fluid into and out of the tube as well as carry a spring member for cooperating with one of the valve members in the valve assembly.  An improved coupler mechanism is employed in operating the valves while avoiding inadvertent opening and closing of the valve assembly.  A handle is provided on the coupler for moving the valve actuating elements between an open and a closed position.  A locking mechanism on the coupler prevents engagement and disengagement of the coupler while it is in the open position.

Abstract: ABSTRACT OF THE DISCLOSURE A closed loop assembly for dissolving a layer from an article by exposing  the article to a leaching solution having a predetermined boiling temperature.   The assembly includes  a  sealed  reaction  container  including  an  inner compartment to contain the leaching solution and the article, a recirculation system connected  to the reaction container for  receiving  boiled  off  leaching  solution  vapor  and condensing the vapor and returning the vapor to the reaction container,  and a heater for heating the article within the reaction  container  above  the  boiling  temperature  of  the leaching solution.         The assembly performs a method of dissolving the layer from an article by exposing the article to the leaching solution. The steps include placing the article in the inner compartment of the sealed reaction container containing the leaching solution, heating the article to a temperature above the boiling temperature of the leaching solution to increase the  corrosion  rate  of  the  outer  layer  of  the  article, conducting and condensing boiled of leaching solution vapor in the recirculation system,  and selectively returning the collected leaching solution to the reaction container.

Abstract: LAMINATED ELEMENT, THERMAL PRINTER AND    PROCESS FOR LIFT-OFF CORRECTION                      Abstract A ribbon (22) in thermal printing has an outer layer (50) which adheres to printed characters at somewhat elevated temperatures but is non-tacky at room temperatures.  The embodiment has an active layer of an ethylene vinyl acetate copolymer, an acrylic polymer, and carbon black.  Thermal printing is conducted from the preferred ribbon by setting the switch (44) for heating to temperatures higher than the lift-off temperature.  Lift off is accomplished by returning to the printing position of the error and setting the switch (44) for lower voltage to the printing electrodes (9).  The guide (29) allows cooling so that the bond is set before the ribbon (22) is pulled away.

Abstract: Abstract of the Disclosure A safety tire and wheel assembly which includes an improved multiple-piece wheel rim assembly for preventing inflation and/or venting to atmosphere when the rim assembly components are improperly assembled, and an improved safety insert      mounted on the wheel rim base for supporting the tire tread during operation following loss of inflation pressure.  The wheel rim assembly includes telescoping rim segments and an O-ring             normally captured in compression between opposing portions of the rim segments for sealing the tire cavity.  Air bleed passages             are formed in one rim segment adjacent the sealing ring externally of the cavity to vent the tire cavity to atmosphere when sealing compressive stresses are absent from the O-ring as in the event of improper assembly or disassembly.  The safety in-sert      includes a ledge      normally disposed within the tire cavity and having a radially facing surface roughened by a circumferential series of axially extending splines     .  Encapsulated lubricant      is carried by the insert in a position to be fractured by the tire tread upon loss of inflation pressure so that the lubricant is spread over the tread-engaging insert surface and retained adjacent the surface between the splines.

In the burner according to the invent-ion the fuel is continuously fed (1) into the combustion space (9).  The combustion air is fed (4) to the space (10) between the tubular parts (2,3) and from thereon through the lower holes (11) in the primary air flange (7) to the perforations (12) in the grate (5) below the combustion fuel layer. The secondary air is led through the flange (7) upper part by way of the turboelements (14) and air slits (13), as a horizontally swirling air flow through the combustion chamber (9) to the furnace, where gases are burned while flowing in at a horizontal level. The flame flowing on this horizontal axis combusts ? any burning fuel which may have fallen to the bottom of the furnace. The ashes are extracted through the open mouth of the combustion chamber (9) to the bottom of the fur-nace, partly fused and partly dry. Alternatively ashes fall to the feed base located in the combustion chamber (9) from which it is extracted from the boiler.
