Title: Vacuum lift transporter with foil curver
Inventor: WOSSLER MANFRED
IPC: B65H5/14
Filed: 1977-12-28
Granted: 1980-08-12
Abstract: ABSTRACT OF THE DISCLOSURE A system is disclosed for picking up, depositing and transporting thin foils by use of a vacuum lifting device.  The vacuum lifting device is conveyed on a traverse from a foil receiving station to a foil depositing station.  At the depositing station a transport frame is provided on guide rails to permit conveyance to a processing station.  At the receiving station the vacuum lifting device picks up the foil by suction at a central region of the foil such that the foil will be suspended in a curved fashion from the vacuum lifting device.  At the depositing station, the vacuum lifting device is lowered so as to permit ends of the foil which are downwardly extending on both sides of the vacuum lifting device to be pushed beneath open foil clamps on the transport frame.  Subsequently the clamps are closed and the foil is maintained in an extended, wrinkle free arrangement for conveyance to the processing station.

Abstract: RCA 71,166 FLAT PANEL DISPLAY WITH BEAM INJECTION CLEANUP                           Abstract An evacuated envelope includes spaced, substantially parallel front and back walls, and a plurality of spaced, parallel supports between the front and back walls and forming a plurality of channels.  A gun structure at one end of the channels directs at least one beam of electrons along each channel.  In each of the channels is at least one beam focusing guide which confines the electrons in the beams, but allows the beam to be selectively deflected out of the guide toward a phosphor screen on the inner surface of the front wall.  Each of the focusing guides includes spaced walls between which the electron beam passes.  Between the gun structure and each of the focusing guides is a beam clean-up section.  The beam clean-up section serves to remove from the beam those electrons whose position and velocity vector are such that they would impinge on a wall of its focusing guide during the travel of the electron along the guide.

The powder is partially compacted and magnetically aligned in a first press equipped with magnetizing means.  It is then transported in the tooling, which protects the powder from being disturbed during the transportation, to a second press where it is further compacted under much higher loads.  The compacts thus formed can be further processed to form thin, curved, densified, permanent rare earth-cobalt magnets particularly suited for use as pole pieces in small, high-torque D.C. motors.

Abstract: ABSTRACT OF THE DISCLOSURE A detector for use in an infrared gas analyser is disclosed.  The detector includes a metallic block housing an inlet port for a measuring light beam and an inlet port for a reference light beam.  A light sensor is positioned in the block for receiving radiation through two multilayer interference filters, one disposed in each inlet port.  A heating coil is embedded in the block and the electrical supply to this coil can be con-trolled by a control circuit.  Because all the components are located in the block their temperature can be stabilized simply by stabilizing the temperature of the block.  Also, the design permits smaller than usual dimensions, thus reducing the thermal capacity and facilitating temperature control.

The device comprises a cooled metallic block having a pair of large opposed faces and a plurality of rows of through-passages interconnecting said faces. Inlet and outlet manifold channels for the melt extend along the rows of passages so that a lateral wall of a manifold channel is formed by its respective face of the block. Partial flows of melt obtained from the flow in the inlet manifold channel are individually cooled in the passages and emerge from the latter sub-stantially perpendicularly to the outlet flow in the outlet manifold channel to produce turbulent mixing.          Preferably a further similar cooling block is provided, acting in series with the first block.

Abstract: TITLE          METHOD AND APPARATUS FOR GENERATING HEAT FROM WASTE FUEL            ABSTRACT OF THE DISCLOSURE           A combustion apparatus is a two chamber wet wood burner with an optional third chamber.  The third chamber is used to blend the combustion products down to the desired pro-cess temperature.         Waste wood is fed into a primary chamber by means of an underfeed stoker.  A conical pile is formed on the grate-covered floor centered above the stoker opening.  Pre-heated underfire air is supplied to the bottom of the pile and both dries and gasifies the wood.  The heat for gasification is developed from the reaction of the fixed carbon in the fuel with the underfire air. High pressure swirl air is admitted tangentially to the primary chamber above the fuel pile.  The swirl air reacts with a small proportion of the pyrolized gases to maintain a steady temperature at the exit from the primary chamber.  The swirl air also centrifugally separates particulate matter from the gas stream leaving the primary chamber.  The total quanti-ty of underfire and swirl air is closely controlled to main-tain substoichiometric conditions in the primary chamber.         Secondary air completes combustion of the pyrolized volatiles in the secondary chamber.  The secondary air is admitted tangentially to establish a rotating mass of rela-tively cool combustion air adjacent to the walls of the sec-ondary combustion chamber.  The air reacts with the volatiles at the base of the secondary chamber, after the volatiles have first been forced radially outward by the presence of a disc-shaped flame holder in the inlet to the chamber.  The ensuing mass of hot flaming products of combustion, centered above the flame holder, spiral upwards within the outer rotating mass of combustion air and out the restricted outlet of the secondary chamber.         The flame holder also acts as an effective barrier to the passage of finite sized particles of unburnt wood waste up the core of the concentric vertices in the primary and sec-ondary chambers.         A heat exchanger drawing off hot stack gases suit-ably cooled in a blend chamber can be used to preheat the underfire air.         The controls of the combustion apparatus act to 1) maintain a steady elevated temperature of pyrolized volatiles supplied to the secondary combustion chamber, 2) maintain an overall constant centrifugal separation force on particulate matter within the combined primary and secondary chamber, 3) maintain constant secondary and blend chamber exit tempera-tures, and 4) maintain constant underfire temperatures over a wide range of waste wood quantities and moisture contents.
