Patent NO-174115-C (NO)
Inventor: RAJALA VELI-MATTI
IPC: D21D5/02
Filed: 1989-03-06
Abstract: The invention relates to a device for screening pulp, comprising a screen drum (2) provided with holes for the passage of an accepted pulp fraction therethrough; and a blade (10) for a screening device. The device comprises straight blades (10) wiping the surface of the screen drum (2) and extending in parallel with the axis of the screen drum (2). Reject which does not pass through the screen drum (2) is removed through a reject discharge opening (5) at the other end of the screen drum. For transferring the reject from the surface of the screen drum (2) to the reject discharge end, the surface of the blades (10) is on the screen drum side provided with grooves (11) so inclined that the front end of the groove (11) is closer to the pulp input than the backward end of the same groove (11). Thereby each groove (11) in the blades (10) causes the reject to be transferred towards the reject discharge opening (5).

Title: Customer programmable automated integrated voice/data technique for communication systems
Inventor: GAWRYS GEORGE W
IPC: H04Q3/00
Filed: 1990-08-09
Granted: 1995-01-17
Abstract: The present invention enables multi-windowing agent computer terminals, that answer a variety of, e.g., telemarketing calls, to (i) receive call-related information from a communication system at an agent terminal for automatic display in a "telephony" window, and (ii) automatically send such information to a host computer system application software and retrieve caller desired information based on the calling or called number for display in a "host application" window without requiring a caller to provide verbal information. The present invention also enables an agent terminal to automadcally transfer caller-related information from one window to another window via programmable function key commands which can be programmed by a user/system administrator regarding what information is to be copied and where and when to copy it. This allows the user/system administrator to program the system to (1) retrieve information using the received call-related data without routing caller data to the host computer application software prior to its delivery to the agent terminal, and (2) automatically transmit collected data to the host database at a call's conclusion.

Title: Main memory control system
Inventor: HIROSAWA TAKASHI
IPC: G11C11/4072
Filed: 1990-08-31
Granted: 1994-02-08
Abstract: ABSTRACT OF THE DISCLOSURE    A main memory control system has an initial data generating circuit for generating initial data, an initialization control circuit for activating an initialize signal in response to an initialize command, and a refresh control circuit that generates refresh addresses.  When the initialize signal is inactive, the main memory control system performs normal read, write, and refresh operations.          When the initialize signal is active, the main memory control system selects the initial data by means of a data multiplexer and performs only write operations, writing the initial data at refresh addresses generated by the refresh control circuit.  If the main memory has an interleaved structure, the initial data are written in all leaves simultaneously.

Granted: 1994-05-31
Abstract: ABSTRACT          The  present  invention  relates  to  a  spring assembly for the seat portions or areas of upholstered furniture.   The spring assembly provides a frame and a series of different spring types supported in a generally parallel arrangement within the frame.  The spring assembly includes a plurality of upper spaced,  elongate sinuous springs extending between and above a pair of opposing front and back members.  Located in the central region of the assembly is a rectangular quad coil spring mounted on the  two upper  and  lower wire  stringers.    The  spring assembly is provided with a pair of  Z-shaped  sinuous springs, one located on each lateral side of the quad coil.          The Z-shaped springs are mounted on lower elongate sinuous springs extending between the front and back members.  The upper portions of the Z-shaped sinuous springs and the upper elongated sinuous springs are secured to the upper and lower stringers for stability and to prevent lateral movement of same.  The Z-shaped springs provide for local support independent of the central quad coil.  The spring assembly provides a differential response across the top surface thereof in response to a user sitting thereon.          When  several  such assemblies are mounted adjacent one another,  the  resulting  system  provides  for  relative independent spring support between adjacent users.

Abstract: A fuzzy feedback controller is designed as follows:   A deviation between a process value and a set value,  and a variation of the deviation are obtained with the aid of an arithmetic memory device, and the deviation and the variation of the deviation are normalized with normalizing devices.  A fuzzy inference operating device performs a fuzzy inference by using the deviation and the variation of the deviation thus normalized, to obtain a control output variation.  The control output variation is normalized with another normalizing device.          The control output variation .DELTA.u thus normalized is added to the preceding control output in an addition device, to form a new control output, which is applied to an operating device.  A parameter adapting device makes normalizing parameters adaptive according to the response waveform of the process value.

Abstract: A mat of reinforcement material, such as glass fiber reinforcement material, is manufactured by forming a layer of continuous strand or chopped fibers on a conveyor belt and conveying the layer along a defined path. At a location downstream of the application of the layer, the layer of fibers is coated with a binder in the range of 2.0---10.0 weight percent, either a microwave-sensitive binder or an ultraviolet-sensitive, binder and the binder-coated layer is fed into a radiation tunnel which includes a compression stage and a curing stage. In this radiation tunnel, the binder-coated layer is compressed to a desired density/thickness ratio and cured, the compression and curing occurring in stages, and the resulting mat is taken from the conveyor belt and wound up for storage. The curing energy is supplied as the selected microwave or ultraviolet radiation and the radiation is applied between sets of compression rollers or through compression rollers or webs which are transparent to the specific electromagnetic energy.
