Abstract: TITLE:       METHOD AND APPARATUS FOR CONTROLLING THE     REFINING OF FIBROUS PULP GRIST IN A DRUM REFINER          INVENTOR:    ARNE JOHAN ARTHUR ASPLUND               ABSTRACT OF THE DISCLOSURE     Method and apparatus for controlling the refining of fibrous lignocellulosic pulp in a drum refiner in which the pulp stock, or grist, is conveyed into a cylindrical stationary drum and propelled therein in a linear direction in a pulsating fashion by a co-axial rotor comprising a plurality of wings which attack the grist in a wedging action as it is pushed ahead of the leading faces of the wings and which induce in the grist internal frictional shear forces while it is forced through a gap defined between the leading edges of the wings and a series of shear means arranged axially along the interior surface of the stationary drum.  The process is controlled by co-ordinating the angle of attack on the grist by the wings and corres-ponding variations in the gap clearance with the energy demands or mechanical power input.

Abstract: ABSTRACT OF THE DISCLOSURE           A frangible or breakaway valve for use in a flexible tube.          The valve comprises two parts: a tubular portion with a closed end and an elongated, generally rigid handle breakably attached to the closed end. The elongated handle has projections which frictionally contact the interior surface of the flexible tube and prevent the elon-gated handle from moving back into a closed position once the elongated handle has been broken. The valve may be used in conjunction with tubing and a plastic container of dialysis solution. The valve is opened by breaking away the elongated, generally rigid handle and moving "walking" the rigid handle down the tube by folding the tube back and forth upon itself. The projections on the rigid breakaway handle have sufficient frictional contact with the inside of the tube to assure that the handle will not move back into contact with the tubular portion, and the valve will remain open.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of attaching sliders and cop end stops to a pair of continuous slide fastener stringers, each stringer having seccessive spaced groups of coupling elements mounted on continuous stringer tape and interengaged with opposed complementary groups of coupling elements on the other stringer tape, there being successive pairs of opposed blank tape por-tions between the successive spaced pairs of coupling element groups.  One of the, successive pairs of opposed blank tape portions is spread apart.  A slider is set and retained at a first fixed point between the spread pair of opposed blank tape portions.  The opposed blank tape portions are then released so as to engage shoulders of a guide channel of the slider.  Then the stringers are fed backwardly so as to thread the opposed blank tape portions through the guide channel of the slider.  After that, the stringers are fed forwardly until end portion of an adjacent pair of coupling element groups are introduced into the guide channel of the slider.  A pair of top end stops is set and retained at a pair of transversely spaced second fixed points so as to be threaded through the opposed blank tape portions.  The stringers are then fed for-wardly until endmost disengaged coupling elements reach the top end stops retained at the second fixed positions.  Finally, the top end stops retained at the second fixed points are clinched about the respective inner longitudinal tape edges of the stringer tapes.  An apparatus for carrying out this method is also disclosed.

Abstract: Title:    METHOD OF REGENERATING AN           AMMONIACAL ETCHING SOLUTION     ABSTRACT OF THE DISCLOSURE       In addition to catalyzing the reoxidization of spent alkaline etching agent, the suspension of activated carbon powder in the etching solution also increases the speed of etching when the etching solution is recirculated in the etching of printed circuit boards. The ammonium sulfate etching solution is set to a pH of about 9 by the addition of ammonia gas.  In the recirculation of the etching solution, a part of the solution can be freed by filtration from sus-pended carbon particles and passed through the cathode and anode chamber= of an electrolysis cell for the recovery of the etched metal by deposition at the cathode. The activated carbon powder for this purpose is calcined before use, at a temperature of between 900 and 1200 °C in vacuum or in an atmosphere that is inert, reducing, or only slightly oxidizing as in the case of an  atmosphere containing carbon dioxide, water vapor or both, in a concentration that does not appreciably oxidize the carbon particles.

The control system comprises an ejector for drawing concentrate from the reservoir jar and a pair of coaxial, independently rotatable valve elements, one, act-ing with fixed structure, serving to turn the water supply off or direct the water into the chemical concentrate jar or through the unit to the spray nozzle, the other, operat-ing in conjunction with the first valve element, control-ling by means of flow resistance in a labyrinth, desirably in conjunction with an orifice metering disc, proportionate feed from the jar of chemical concentrate to the main water stream.  Proportionate feed may be accomplished without the flow resistance control by appropriate dimensioning of the ejector.  The ejector is itself novel in that it is made of plastic material by injection with a single mold having a single core forming the entire length of the ejector passageway.  The spray nozzle includes an adjustable, cam-controlled baffle for selectively achiev-ing a downwardly or upwardly directed spread spray pat-tern or a jet stream.
