Abstract: A fluid feeding device in which a battery, a DC motor and an electric pump are housed within a portable case. A fluid in a fluid container mounted on and communicated with the electric pump is discharged from a fluid discharge gun in a predetermined quantity or continuously. The fluid feeding device is compact in size and light in weight so that an operator can easily carry it in a wide range, whereby the fluid feeding device can be easily used at a high place or at a narrow place. The fluid feeding device is used, for instance, for feeding grease into mechanical bearings or the like.

Abstract: Upper and lower vortex chambers are disposed immediately below a calcining furnace for calcining powdery raw materials. The scattering clinker particles from a fluidized-bed burning furnace are trapped in the lower vortex chamber and are returned to the fluidized-bed burning furnace so that the scattering clinker particles are positively prevented from flowing into the upper vortex chamber and the calcining furnace.

Abstract: A multi-pass rolling method which permits a multi-pass rolling-mill stand to perform multi-path rolling and still stabilize the rolling operation by preventing lateral deviation movement of a metal workpiece being rolled. The rolling-mill stand has three or more work rolls arranged one above the other and the workpiece is simultaneously rolled at two or more points by at least one of the work rolls. Directly or indirectly roll gaps are detected on the work and drive sides of at least one pass by sensors. A difference signal from the output signals of the sensors is obtained thereby determining a roll gap difference. Control devices are provided which are responsive to the difference signal for independently changing the roll gaps on the work and drive sides.

Abstract: In a turbocharger of the type in which a turbine and a compressor are disposed in back-to-back relationship and bearings are disposed on the suction side of the compressor, the turbine and the compressor are isolated thermally from each other; the service life of the antifriction bearings is increased; lubrication oil sealability is improved; and machining of a shaft is facilitated.

Abstract: In an internal manifold type laminated fuel cell, in order to feed two kinds of gases to a cathode and an anode, respectively, through a separator plate, spacers for separately supplying the gases to the cathode and the anode, respectively, are disposed over the surfaces, respectively, of the separator plate, whereby separation and sealing between the two gases are ensured.

Abstract: A screen main body extends in a vessel of desalting-filtration device to section the interior of the vessel into an upper chamber in communication with an inlet through which a liquid to be treated is charged into the vessel and a lower chamber in communication with a liquid outlet. An ion-exchange filtration layer is disposed between the screen main body and the liquid outlet. Ferromagnetic filter elements which form a magnetic filtration layer when magnetized are piled on the screen main body such that the surface of the piled filter elements becomes free. Magnet insertion tubes made of a non-magnetic material vertically extend through the screen main body and a permanent magnet is vertically movably inserted into each magnet insertion tube so that when the permanent magnet is inserted into the magnet insertion tube, the filter elements surrounding the magnet insertion tube are magnetized; but when the permanent magnet is pulled out of the magnet insertion tube, the filter elements are de-magnetized.

Abstract: The present invention is directed to a method and apparatus for forming seam welded tubes in which the positions of cage rolls are adjusted in accordance with the thickness, substance and size of a material to be formed into a tube in a process for forming a tube blank for a seam-welded tube by using cage rolls.

Abstract: A turbine casing, a shroud and a gas outlet cover together define a closed doughnut-shaped space. A nozzle driving ring inserted in the space is slidably clamped by the turbine casing and the gas outlet cover. Nozzle shafts extending from nozzle blades are connected through links to the nozzle driving ring. The nozzle driving ring can be driven from outside the space. The nozzle driving ring for simultaneously varying the angle of the nozzle blades is restrained in the axial direction effectively with a high degree of accuracy.

Abstract: A fan blade in which a leading edge piece made of a hard sintered product is attached to the leading edge of a fan blade main body over along substantially 3/4 to 1/4 from the tip thereof so that a useful life of the fan blade is prolonged.

Abstract: In an endless track type continuous casting installation of the type in which a mold cavity having variable thickness for a casting is defined by the combination of block molds each of which is of an L-shaped cross section and which are connected with each other in the form of a loop, thereby providing each of a pair of endless tracks, safety is ensured with the block molds of the pair of endless tracks are combined to define a mold cavity.

Abstract: An effective method for heat treating metal pipe lines and especially a metal pipe line whose construction is so complicated as to tend to leave an air pocket therein.

Abstract: A magnetic filter comprises a vessel, a screen main body disposed within the vessel for partitioning the vessel into an upper chamber and a lower chamber, a filtration layer formed by particle-like filter elements magnetized by magnets and disposed on the screen main body. Corrosion products entrained in a liquid charged into the upper chamber are removed by the filtration layer.

Abstract: A bearing device for a turbocharger wherein a bearing casing is interposed between a turbine casing and a compressor casing; disposed within a bearing housing of the bearing casing are a ball bearing on the side of the turbine and a ball bearing on the side of the compressor both of which is supported by a one-piece oil film damper which is floating; and a pin is loosely fitted into the oil film damper and the bearing housing so as to prevent the rotation of the oil film damper.

Abstract: In disposing an insert or inserts within a blow-molded product, before the blow molding step is started, an inner supporting device supporting the insert at an end thereof is inserted into a parison and then the mold is closed so that the insert is made into contact with the parison. Thereafter the blow molding is effected so that the insert is securely welded to the parison.

Abstract: According to the present invention, white cement clinker particles are not burned in a rotary kiln and the burned clinker particles are not immersed in the water to be cooled. White cement clinker raw materials are burned in a fluidized bed burning furnace with a fluid bed or a spouted bed and the clinker particles thus burned are reduced with a reducing gas. The clinker particles thus reduced are first cooled with the water which is sprayed over the clinker particles and then further cooled with the air. The white cement clinker raw material particles fed into the fluidized bed burning furnace are burned into clinker particles while forming a fluidized bed and then the clinker particles thus burned drop through a jet injection pipe into a reduction chamber disposed below the burning furnace and are reduced. The clinker particles thus reduced are rapidly cooled to 600.degree.-700.degree. C.
