Abstract: Improved Pseudomonas exotoxins of low animal toxicity and high cytocidal activity are described. Substitution of positively charged amino acid residues with an amino acid residue without a positive charge provides markedly changed exotoxins. Conjugation of the new exotoxins with suitable targeting agents provides cytocidal specificity for killing desired cellular entities.

Abstract: A method for producing substantially ink-free pulp from recycle printed paper comprising first pulping the recycle paper in a hydrapulper with at least water and an agglomerating agent thereby producing a pulp. Ink particle agglomerates in the pulp are then removed by screening the pulp through at least one screen and by cleaning the pulp in a cyclone cleaner. Pulp together with small ink particles that escape the prior separation stages is then conducted from the cyclone cleaner through a standpipe at a consistency of about or less than 1% where particles of ink associate with small air bubbles and are elevated to the surface of the pulp where they accumulate as a froth which may be removed by overflowing.

Abstract: Method of recovering energy from waste liquors from pulp processes, wherein the waste liquor is burned in a waste liquor recovery boiler and energy is recovered from the flue gases by producing saturated or partially superheated steam in the recovery boiler. According to the invention, a portion of the waste liquor is gasified in a gasifying reactor in order to produce combustion gas. The combustion gas is burned in a separate superheating boiler, in which the steam produced in the recovery boiler is superheated.

The plenums are located at positions spaced laterally outward from the nozzle assemblies.

Abstract: A tong head assembly for a glass blowing machine includes multiple tong mechanisms. Each tong mechanism has a tong extending from the bottom of a cylinder. The tongs are adapted to grasp a blown container. The cylinders are mounted for independent rectilinear and angular movement in the tong head assembly in order to compensate for misalignment of the tongs with the glass container to be grasped.

Abstract: A method of treating the edges of a fiber web is provided wherein a pressing device device conveys and presses a fiber web through a pressing gap of a pressing station of the device. The station includes a pressing roll and a counter roll. The pressing roll has a roll shell. A pressing shoe is disposed within the roll shell and pressing units are disposed substantially along a width of the pressing shoe transverse to the direction of movement of a fiber web through the pressing station. The pressing units press against the pressing shoe which in turn presses a pressing surface of the shoe against an inner surface of the roll shell in a series of zones. The pressing units including pressing/pressure relief elements. The pressing force of the pressing/pressure relief elements is reduced in a step-wise fashion, zone-by-zone, from a normal operating level to a lower level in a region that includes the fiber web edges and the pressing shoe ends.

Abstract: A computer controlled system for high speed surface mount adhesive placement in circuit board production includes a dot generator supported for motion along the X, Y and Z axes. The dot generator ejects a jet of viscous adhesive that breaks away from the nozzle of the dot generator as a result of its own forward momentum. The system includes an automatic circuit board conveyor with adjustable width and pneumatically operated lift and lock mechanisms. The system runs through a self-diagnostic set-up procedure and dot calibration routine. Dot size and location are monitored through a video camera and vision circuit. A computer interfaces with the vision circuit and with motion, dot generator and conveyor controllers so that the system can operate in a high volume production assembly line. Application programs are executed by the system computer typically utilizing CAD data from a disk or a computer integrated manufacturing (CIM) controller.

Abstract: A paper rawstock web is wet densified on a papermachine at a moisture content greater than about 20% and less than about 50%, and preferably from about 25-35%, in a calender device at nip pressures greater than about 3000 psi, and preferably within the range of from about 3000-6000 psi, to provide fiber springback resistance and irreversibly smooth surfaces which are substantially resistant to loss of smoothness upon rewetting, as for example in a subsequent surface sizing or coating process. Wet densification according to the present invention produces a web having greater density and increased internal bond strength, as compared with webs treated by conventionally known methods, to achieve the irreversibly smooth surfaces.
