Granted: 1999-01-05
Abstract: A four-wire line unit interface circuit used on four-wire line units in a line shelf of a digital loop carrier provides all of the logic necessary to access a subscriber line to a line unit interface bus connected to common equipment within the line shelf.  Information received from the common equipment includes signaling data, configuration data and provisioning data which is reconfigured and processed by the line unit interface circuit for controlling the subscriber line.          Configuration data from the common equipment is decoded to assign time slots on a line unit interface bus to the various channels serviced by the line shelf and to further provide for a timing offset between the transmit and receive strobes provided to each subscriber line circuit.  An asynchronously operating microprocessor is provided on the four-wire line unit, and a microprocessor interface is provided to interface the asynchronously operating microprocessor with the data provided on the line unit interface bus.  CODEC and Equalizer devices provided on the four-wire line unit are provisioned and audited through the interface circuit.

Title: Sheet for molding fiber-reinforced resin and method for producing it
Inventor: KOHAMA KATSUMI
IPC: B29C35/08
Filed: 1991-09-25
Granted: 1995-02-14
Abstract: This invention provides a moldable fiber reinforced resin sheet which is suitable for preparing a fiber-reinforced resin molding having excellent coloured conditions.  The invention also relates to a method for producing the sheet.  The moldable sheet of the present invention comprises a fiber-reinforced resin layer and a coloured surface resin layer laminated to the first layer and has, in the fiber-reinforced resin layer, a fiber-reinforced coloured resin layer adjacent to said surface resin layer.  The fiber-reinforced coloured resin layer is coloured in a colour similar to that of the surface resin layer, and has a fiber-reinforced transparent resin layer arranged on the surface of the side opposite to the surface resin layer.  The transparent resin layer being curable with ultraviolet radiation.  The first method for producing the sheet comprises carrying out a viscosity-thickening treatment on a resin layer first laminated out of the fiber-reinforced coloured resin layer and fiber-reinforced transparent resin layer.  The second method for producing the sheet comprises forming a fiber-reinforced transparent resin layer and, on this layer, laminating a fiber-reinforced coloured resin layer without the viscosity-thickening treatment on the transparent resin layer, and then, laminating a surface resin layer, if necessary, after carrying out viscosity-thickening treatment on the fiber-reinforced resin layers.  The third method for producing the sheet comprises forming a surface resin layer and carrying out a viscosity-thickening treatment on this layer, and independently, after forming a fiber-reinforced transparent resin layer, on this layer, laminating a fiber-reinforced coloured resin layer without the viscosity-thickening treatment on the transparent resin layer, and then, laminating the surface resin layer on the fiber-reinforced coloured resin layer.

Filed: 1993-04-08
Granted: 2005-08-16
Abstract: The invention relates to an applicator beam in a size press comprising a nip formed by a pair of press rolls between which a paper or board web is passed. The press rolls are provided with coating devices for spreading films of coating agent onto the faces of the rolls. The coating devices are mounted on applicator beams placed in the transverse direction of the machine. The applicator beams are linked pivotally on the frame of the size press or on the loading arms of a displaceable roll by means of a pivot shaft arranged transverse to the machine direction. The applicator beams are also provided with pivot cylinders by whose means the applica-for beams can be pivoted between a closed position, i.e. the operating position, and an opened position, i.e. the service position. In accordance with the invention, in its cross section taken in a vertical plane in the longitudinal direction of the machine, the applicator beam is shaped so that at least the curved outer face of the applicator beam that is facing away from the corresponding press roll is curved. Moreover, the pivot shaft of the applicator beam is arranged so that when the applicator beam is pivoted around its pivot shaft, the distance from the curved outer face of the applicator beam to the other constructions of the machine placed close to the applicator beam, such as the tending bridge, remains substantially unchanged.

Filed: 1994-08-02
Granted: 1999-05-11
Abstract: A spreader for granular material such as sand comprises a trailer adapted to be pulled behind a vehicle such as a tractor or other utility vehicle.  A frusto-conical bin forms a hopper for a granular material to be dispensed and directs the material into a spreader housing where the material is impelled outwardly through a discharge opening by a rotating impeller.  The impeller and an orbital rotating bin sweep arm are driven by coaxial drive shafts via a belt and pulley mechanism.  A frictional tire engages the upper rim of the bin and propels the sweep arm in an orbital path.  The material discharge rate and discharge pattern are controllable by a slide gate and interchangeable cover plates which vary the size of the discharge opening.  The impeller and bin sweep assembly may be driven by an internal motor or from the towing vehicle by a power take-off drive.
