  • Patent number: 5705031
    Abstract: In a kraft pulp mill, a process and apparatus for removing and washing dregs from green liquor so that the pH of the dregs is below "hazardous waste" levels. Specifically, green liquor clarifier underflow is filtered using a simple non-precoat cassette filter to form a first dregs cake. The dregs cake is diluted, preferably with water. The diluted dregs cake is then filtered in a precoat dregs filter to produce a dregs cake that is at least 50% solid and has a pH of about 12.0 or less.

  • Patent number: 5598774
    Abstract: Two rolls, more particularly embossing rolls are provided which are pressed against each other by pneumatic cylinders for the purpose of fashioning a flat material passing between the rolls. The ends of one of the roll axles are journalled in slides which are actuatable by the cylinders in such a manner as to be deflectable in the pressure direction and in the travelling direction of the material. The elastically suspended roll is thus capable of automatically adjusting itself in such a manner that the axles of the two rolls can adjust to irregularities of the flat material and thus allow a disturbance-free and qualitatively optimal treatment of the material.

  • Patent number: 5594289
    Abstract: On a rotor which is fixed to a rotatable rotating shaft, a plurality of permanent magnets are disposed along the direction of rotation such that the same magnetic pole type thereof face outward. In the same way, balancers are disposed on the rotor for balancing the rotation of this rotor. Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor. At the outer periphery of the rotor, an electromagnet is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor. According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets.

  • Patent number: 5584692
    Abstract: In a tensioning gripper with a ring and a coaxially arranged rotary pin, both the ring and the pin are provided with a slot suitable for receiving a matrix to be tensioned. The slot of the rotary pin has a symmetry plane parallel to the longitudinal axis of the rotary pin. The sides of the slot are composed by two angled portions which are arranged symmetrically on both sides of the symmetry plane and both portions converge towards the longitudinal axis of the rotary pin, the two vertices of the portions being opposite and adjacent one another. Such a slot allows easy introduction and gripping of the matrix until, by rotating the pin, the matrix is held and tensioned.

  • Patent number: 5579624
    Abstract: The fastening device for objects, more particularly cladding panels or parts of apparatus, comprises a profile bar receiving the object to be fastened. The profile bar is essentially formed of a center profile and a respective adjacent lateral profile on both sides which are designed in such a manner that the center profile and one of the lateral profiles form a respective continuous clamping channel receiving a portion of the object to be fastened. This allows a very simple attachment of a variety of objects without any visible fastening elements.

  • Patent number: 5579290
    Abstract: The stator of the motor comprises two pole pieces (1, 2) which are axially staggered. An axially magnetized cylindrical rotor (5) is disposed in the openings or bores of said pole pieces. The rotor (5) is provided with an external toothing (3) which is continuously engaged with an internal toothing (4) of the stator. In the unexcited stator, the rotor (5) assumes a stable position by attraction to the pole pieces (1, 2). Due to the excitation of the stator by a pulse having a suitable polarity, the rotor is displaced to a diametrically opposed stable position. The toothings (3, 4) stay in engagement during said displacement, resulting in an angular displacement of the rotor, the angle being defined by the difference of the number of teeth of said toothings (3, 4). The motor allows a miniaturization and a simple control by alternating pulses of opposed polarities.

  • Patent number: 5573281
    Abstract: The adapter for attachment onto an outlet of a dispensing means such as a mixing device, comprises a connecting part for attachment to the outlet and an outlet portion to which other parts can be connected or which can be a specially formed outlet itself. This connecting part comprises a cylindrical or an approximately frusto-conical internal surface part having a self-cutting thread for attachment onto an external surface of the outlet of a mixing device or other dispensing device. Such an adapter can be easily attached to the outlet of a standard static or dynamic mixer or other dispensing device having a stepped external surface, thus eliminating the necessity to keep an inventory of mixers with different outlets or outlet connections.

  • Patent number: 5572073
    Abstract: Disclosed is an AC power module for controlling the level of power to multiple electrical devices such as lights and household appliances according to control signals supplied from a processor unit. The apparatus utilizes low voltage control signals which are synchronous with the standard AC power supply to control several solid state relay which in turn regulate the AC power supplied to the devices. Each relay is optically isolated from the module. The module incorporates additional terminals through which back-up switching or control of additional relays (with different power ratings) may be provided.The module may be constructed on a single printed circuit board (PCB) to facilitate installation and removal. According to this embodiment, the PCB has pins which matably attach to a corresponding number of L-shaped tabs provided on a standard electrical box.

  • Patent number: 5569147
    Abstract: A method and a device for producing corrugated strip packaging parts to be used for packaging cylindrical or elongated parts in separate compartments. The device includes a series of form bodies arranged on an endlessly rotating belt. The form bodies have essentially the same inside cross-section as the lower loops of the corrugated strip material formed by the device and are joined together at their base flanks by elastic material areas. The belt is guided over rerouting points that temporarily spread apart two adjacent form bodies to form an enlarged intermediate space. A form tool is arranged adjacent one of the rerouting points to engage and press the material of the packaging part into the enlarged intermediate space.

  • Patent number: 5562275
    Abstract: A flexible spindle suitable for transmitting a torque as well as an axial thrust is constituted by a plurality of helical spirals of wire all of the same length. Each spiral has opposite winding directions to the winding direction of the adjacent spirals and the outer diameter of each spiral is equal to the inner diameter of the spiral which surrounds it. The terminal ends of the spirals are assembled integrally with each other and with the terminal ends of a flexible member situated inside the innermost spiral. Each sprial has a length which is equal to that of the other spirals as measured along their axis when these are in their bent operating position and under those conditions under which they are designed to transmit torque and thrust, with the flexible spindle resulting not to be radially or longitudinally deformable when under stress, thus transmitting the forces without loss.

  • Patent number: 5547110
    Abstract: The metering device comprises a housing, defining at least one inlet for the material to be metered and at least one outlet for that material, and at least one rotatable ball driven by a shaft, the ball having a transverse bore containing a shuttling ball moving linearly in the bore between two seats and seals against the one or the other seat. The rotatable ball is captured between the seats and seals under pressure against the outlet seat. Such a metering device allows an exact metering, in shot or rapid shot resulting in near continuous flow form, has great simplicity of construction with few working parts such as that it may easily be placed at the dispensing end of a pressure transfer system for liquids and gases and acts as shut off valve between metering use such that it prevents stalled hydrostatic fluid pressure behind the metering device from causing a flow surge ahead of the metering device at start up.
