Abstract: METHOD AND SYSTEM FOR MELTING A CHARGE OF BULK SOLID METAL                    Abstract of Invention A method and system of melting a charge of metal in a closed hearth wherein the metal has a first high thermal conductivity when solid, a second low thermal conductivity when liquid and a given melting temperature below about 1600°F, such as aluminum.  The method and system involves the use of a plurality of heaters having a total high heat capacity sufficient to melt the metal in a given time and sufficient to drastically increase the temperature of the metal when the metal is in the liquid state.  This method and system comprises operating the burners at the high heat capacity until a control temperature associated with the hearth and separate from the metal reaches a given value, modulating the burners to maintain the control temperature generally at this given value, turning said burners to a minimum capacity drastically below the high heat capacity after only part of the metal has melted, then allowing the furnace to stabilize whereby thermal energy absorbed by the hearth is combined with the low heat capacity of the burners to finalize melting of the metal and modulating the burners to maintain the control tempera-ture to another value between the first high value and the melt-ing temperature of the metal but substantially closer to the melting temperature of the metal during at least the rapid heat equalization cycle and during at least the initial portion of the holding and/or conditioning cycle.  After the equalization cycle, the method and system can control the capacity of the burners by a temperature in the molten metal itself.  This molten metal temperature is just below the upper surface of the molten metal bath and prevents overheating of the molten metal and the hearth and compensates for temperature gradients.

Abstract: Abstract A method of and a furnace assembly for bending glass sheets.  Glass sheets (6) are conveyed in bending moulds (5) supported by cars (4) along an upper transport run (2) periodically from one heating sect-ion (10) to another.  In the final heating section, temperature isrisen so high that a glass sheet bends by the action of heat and gravity to conform with the surface of the mould.  Thereafter, a car (4) together with a bent glass sheet is lowered onto a lower run (3) and returned to the outset of a furnace (1).  On cooling, the glass sheets on said lower run emit heat to the glass sheets on said upper run through the open bottom structures of cars (4).  The weight and heat capacity of the cars have been made as low as possible by removing the side and back walls thereof, whereby only the front or leading walls (8) provide locking walls between sections (10) successive in the longitudinal direct-ion of the furnace.

Abstract: MASKING OF HOLES IN CIRCUIT PATTERNS ON           CIRCUIT BOARDS PRIOR TO FLOW SOLDERING     Abstract of the Disclosure A circuit pattern on a circuit board usually has a number of contact areas to which components are soldered.  Some of the contact areas have holes extending through the board for insertion of leads of leaded components, the leads then being flow soldered to the contact areas.  It often occurs that additional leaded components are to be mounted on the board after a first flow soldering step.  However, holes through which the leads are to pass can be closed by solder.  These holes are therefore masked mechanically, by a masking member which contacts the board at these holes, or by tape, or other such method.  The present invention uses a conventional solder resist layer, usually applied prior to flow soldering, extending the solder resist layer over a part of the contact area to the periphery of the hole.  The resist layer extends for at least part of the hole periphery.  This prevents the solder being attached to the contact area at the masked periphery and the hole is not closed by a film of solder.                            - i -

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to an automatic gun which employs case ejectors for extraction and ejection of the cartridge case from a spent round.  The case ejector is also used for arresting the breach block during recoil of the weapon and holding the breech block in an open position so that a new round may be rammed into a final position before actual discharge.  The ejector is exposed to the round in the process of being rammed into the breech, which round, during its thrust towards the home position in the barrel, entrains the ejector so that the breech block is released and may close with the assistance of a spring means placed under tension during the opening of the breech block.  The ejector and the breech block are provided with cooperating arrest and abutment surfaces which take up portions of the kinetic energy of the round while the round is being loaded.  A separate buffer device is also con-nected to the ejector that may amplify the above-mentioned retardation/cushioning.  By such an arrangement, the feeding and ramming speed of the gun may be increased without the risk that each round will jolt against the rear face of the barrel and disturb the breech block in its closing cycle.  Such a disturbance would occasion cease-fire.
