Abstract: TITLE:                   AUTOMATIC PIPETTER          INVENTOR:                CHRISTIAN STAHLI                               ABSTRACT       An automatic pipetter utilizing a syringe having several openings at its end.  A different tubing segment connects with each of these openings and extends into different vials of liquids.  Of these vials, one contains a buffer solution generally used in appreciably greater quantities than the others.  Another vial receive, the liquids from the syringe.  As a stepping motor partially withdraws the piston from the syringe, a tube leading to a vial with unmeasured liquid is open.  When the stepping motor reinserts the plunger into to the syringe, the tube leading to the receiving vial becomes open while the other tubes remain closed.  The tubing segments extending between the syringe and the vials include three sections.  The section closest to the syringe, formed from polyimide, undergoes a minimal change in its volume notwithstanding the negative and positive partial pressures exerted by the piston.  The second section, having a plasticized polyvinyl chloride construction, has greater flexibility than the polyimide portion.  Pinching off this flexible section from the outside provides a valving device for the system. The last section of the tubing consists of stainless steel and runs into the vial to provide a high degree of rigidity.  Coating the inside with dimethyldichlorosilane reduces is rusting and crosscontamination between pipetted liquid.  In operating the pipetter, the buffer should follow the other liquids placed into a single container.  This washes the syringe between samples and avoids carry-over error from one sample to the next. After expelling fluid from the syringe, the stepping motor moves at least one step in the direction of withdrawing the piston but with the outlet open.          This removes the slack in the coupling between the motor and the piston and increases the accuracy in the volume of sample drawn into the syringe.  The pipetter, when called upon to deliver a microliter of a particular liquid, will deliver from .98 to 1.02 microliters at least 90 per cent of the time.

Abstract: ABSTRACT:    Acid digester discharge liquor, from the manufacture of cyanuric acid, containing dissolved triazines and iron, is treated with ammonia until the pH is about 2.5 to 4 thereby precipitating most of the triazines while leaving most of the iron in solution.  The triazines are separated and recycled back to the digester.  The filtrate of ammo-nium salts is useful as a source of fertilizer nitrogen.

Abstract: ABSTRACT OF THE DISCLOSURE         A hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the stangulation of tubular members is disclosed.  The applicator consists of a main body, a clip magazine externally attached to the main body, clip deforming jaws attached to one end of the main body, clip feed means located within the main body and actuating means attached to the feed means and deforming jaws.  In operation, one of many hemostatic clips stored in the clip magazine is fed into the main body and guided to the deforming jaws by the inter-action of the actuating means and the feed means.  When the clip is properly located about a tubular member, further actuation of the actuating means results in the deformation of the clip about the tubular member.  Upon further activation of the actua-ting means, the sequential process of feeding a clip from the magazine and deforming the clip about other tubular members may be rapidly repeated until the supply of clips in the magazine is depleted.

Abstract: A method of controlling the reversing of pneumatic reversible percussive devices for driving holes in earth, wherein, in order to reverse the operation of the device from forward to reverse and vice versa, the supply of compressed air through the feed line is cut off.  Then suction is generated in the feed line, whereby the operation of the device is reversed, whereafter the supply of compressed air is restored. The device performing the method of reversing of pneumatic reversible percussive devices for driving holes in earth includes a hollow housing accomodating therein a reciprocable impact member having a rear working chamber and defining with the housing a front working chamber within the housing.  The rear working chamber receives therein a stepped-diameter air supply bush secured in the rear part of the housing.  Its greater-diameter stage has ports made therethrough.  Accomodated within the greater-diameter stage of the bush is a hollow spring-biased valve element having openings made in the end face thereof, facing the greater-diameter stage of the bush, the apertures being associated with respective valves.  The surface of the valve member, cooperating with the bush, has ports made therein, alternatingly aligning with and closing off the respective ports in the bush upon the hollow valve member being rotated about its longitudinal axis.  This is attained by the internal surface of the bush and the external surface of the valve member defining therebetween a zigzag-shaped groove movably receiving therein a lug.  The compressed air feed line has provided therein a an aspirator adapted to create suction in this line, when the operation of the device is to be reversed.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed for recovery or mining, particularly suitable in winning predominantly hard minerals.  The invention utilizes the sequence of, first, undercutting a layer of the face of a seam at a predetermined depth by producing a cut by a jet of super-pressurized water, second, mechanically breaking off the undercut portion by wedging tools inserted in the cut, and, thirdly, by conveying the recovered material away from the seam working area.  The invention improves the economy of the mining operation and also makes it possible to achieve the best results by selectively adjusting the position of different parts of the machine relative to its frame and also by adjusting and re-adjusting the pressure of the superpressurized water used in generating the cutting jet.

Abstract: RECOVERY OF GAS FROM WATER                DRIVE GAS RESERVOIRS     ABSTRACT OF THE DISCLOSURE         In a method for recovering more gas from natural water drive gas reservoirs than is recovered using present methods, large volumes of water are produced from the reservoir, and/or from the aquifer adjacent to the reser-voir to reduce reservoir pressure.  Residual gas after water displacement is thereby left in the reservoir at a lower pressure than it would have been had such water not been produced.  Since the quantity of gas, in cubic feet corrected to standard pressure and temperature conditions, left in the reservoir at depletion is a direct function of pressure, use of the this method results in increased gas recovery.
