Filed: 1986-11-18
Granted: 1992-10-20
Abstract: ABSTRACT           A  furnace  and process  for  recovery  of  zinc  from sulphide materials,  in which zinc sulphide material together with  an oxidizing  gas  is  introduced  into  a  first  of  two laterally adjacent zones formed by a gas space of the furnace being divided by an upwardly extending fluid-cooled wall which extends  into  a  slag  layer,  thereby producing  zinc  oxide dissolved in the slag and oxides of sulphur, with oxides of sulphur  being  removed with flue gases from the first zone. Conditions are maintained such that circulation and mixing of the slag occurs between the two zones; with a reductant being introduced into the second zone to reduce zinc oxide in the slag to zinc metal vapour which is removed with reducing flue gases.

Title: Press roll
Inventor: HALTTULA KYOESTI
IPC: D21F3/02
Filed: 1987-02-18
Granted: 1990-12-04
Abstract: Abstract of the Disclosure The invention relates to a press roll arranged to interact with a second roll in the wet end of a paper or paper board machine for forming a nip between the rolls. In the press roll a surface arranged to be pressed against the second roll is made of an elastic material for extending the nip. In order to provide a simple and versatile structure, the surface made of an elastic material is formed by a separate shell portion which surrounds a body of the press roll and is posi-tioned over its entire length at a distance from the body. The shell portion is supported to be stationary with respect to the body by means of end flanges provided in the ends of the body, so that the shell portion is able to yield over the entire length thereof radially inwards towards the body locally at the nip point.

Abstract: A magnetometer comprises a transparent spherical photocell (1) filled with natural helium 4He. A laser (2) of the LNA (lanthanum-neodymium aluminate) type excites the photocell. An oscillator (3) generates a soft discharge inside the photocell (1). The electronic magnetic resonance frequency of helium atoms in the excited metastable state is determined on the basis of the light (FT) transmitted by the photocell, under excitation by a radio electric field, and the magnetic induction is thereby found.

Title: 8-phase phase-shift keying demodulator
Inventor: MIZOGUCHI SHOICHI
IPC: H04L27/00
Filed: 1987-07-08
Granted: 1991-08-06
Abstract: ABSTRACT         In order to rapidly bring a 8-phase phase shift keying demodulator into resynchronization upon the demodulator going out of synchronism, a plurality of error signals produced within the demodulator is used to determine whether a signal point of an incoming 8-phase phase modulated signal is usable for controlling a transversal-filter.  An asynchronism signal, which indicates whether the demodulator is synchronized, is derived from the demodulator and being applied to a tap gain control signal generator coupled to the transversal filter.  The tap gain control signal generator is controlled when the asynchronism signal indicates asynchronism of the demodulator.

Title: Method and apparatus for packet-switched network communications measurement matrix display
Inventor: TOMBERLIN JEFFREY
IPC: H04L69/40
Filed: 1987-07-28
Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a communications measurement matrix display for a protocol analyzer which is used to monitor traffic on a packet-switched network.  The present invention allows the protocol analyzer user to see, at a glance, a complete and accurate overview of communications between more than thirty-one nodes on a packet-switched network, over a user selectable range of measurement-time intervals.  The matrix display has two modes.  One mode shows the source versus the destination nodes of the network as a 32-X-32 two-dimensional X-Y grid matrix having thirty one source nodes ordinally indicated along one grid axis and thirty one destination nodes ordinally indicated along the other grid axis.  The thirty second ordinal position on each axis designates any node other than the first thirty one nodes.  A display marker positioned on the grid indicates communication between the source node and the destination node which correspond to the (X,Y), that is, the (SOURCE, DESTINATION), coordinates of the marker.  In a second mode, the display shows the node connections only: the display is simply a 32-X-32 two-dimensional X-Y grid having thirty two nodes ordinally indicated on each axis without direction, such as source or destination, indicated.  The display of the second mode is essentially the display of the first mode folded along its diagonal.  The matrix display, in both modes, is particularly well suited to the IEEE 802.3 Local Area Network packet-switched network.  The matrix display is accomplished using a combination of dedicated hardware and real-time software.  The hardware consists of a so-called address trap machine which is programmed with the addresses of the nodes of the network.  The address trap machine catches the source and destination address of each information packet transmitted on the network transmission medium without disrupting packet transmission.  The address trap then outputs a sixteen-bit word containing the node numbers matched by the source and destination addresses of each frame.  A fast execution software loop collects the counts for each of the nodes and puts the results into a 32-X-32 array.  Higher level software accumulates the array values for the duration of a user-selected measurement-time-interval and quantifies each count based on a user-adjustable legend setting.  The appropriate marker from the user-adjustable legend of traffic volume markers is then presented on the grid matrix display.

Abstract: Abstract Boards (10) that have been separated by a chipless cutting method using an inclined blade, are twisted and, in most instances, this twist has to be corrected before boards that have been produced in this manner can be used.  An apparatus in which a plurality of pairs of rollers (7, 8) are arranged in tandem within a main frame (1) is used to do this. Each pair of rollers (7, 8) can be pivotted about the longitudinal axis of the main frame (1) relative to the preceding pair.  This forms a board guide channel that extends in the longitudinal direction of the main frame (1) and which is twisted approximately about the longitudinal axis of the main frame (1).  The boards (10) that are to be straightened pass through the board guide channel (9) and are permanently deformed, which compensates for the twist that originally existed in the board.     Figure 1.

The fuse tubes of the invention com-pletely eliminate the use of expensive and difficult to fabricate bone fiber conventionally used in fuse tubes of this type.   The preferred fuse tube con-struction is an integrated, synthetic resin body having an outer tubular shell including a thermoset-ting, fiberglass-reinforced synthetic resin matrix, together with an inner tubular arc-suppressing core having a thermosetting resin matrix with respective quantities of an organic fiber and a filler therein. The  filler is preferably hydrated alumina, and is operable  to generate copious amounts of molecular water under arcing conditions; the organic fiber (e.g., a mixture of polyester and rayon) provides a degree of structural reinforcement for the core during manufacturing, and also aids in arc-suppres-sion through the evolution of gaseous products.  The fuse tubes of the invention may be pultruded as integrated,  joint-free  bodies  of  any  convenient length.
