Abstract: ABSTRACT OF THE DISCLOSURE           A method of potting the ends of a bundle of hollow fibers positioned in a casing is provided, for example, in the manufacture of hollow fiber artificial kidneys.  The bundle is inserted into the casing through an open end there-of and the casing ends are enclosed with sealed casing clos-ure member means.  The casing ends are spun, while curable liquid sealant is inserted through side apertures in the casing.   Accordingly, the liquid sealant migrates by the centrifugal force of the spinning to the interior sealed ends of the casing.  After the liquid sealant has cured, the closure member means, sealant and hollow fibers are cut through at each casing end to expose the bores of the hollow fibers.  Alternatively, the closure means can be removed prior to the cutting step.

Abstract: Abstract of the Disclosure A rock bit used for drilling with air as the circulating fluid, and a centrifugal separator to filter liquid and other contaminants from the air diverted to the bit bearings.  The filter generates a fluid vortex with radial vanes, each having plural pitches, located within the shank of the bit.  Bearing coolant passages, located beneath the separator, receive filtered air from a central, filtered air location.  The vortex centrifugally forces the water and other contaminants outwardly into nozzle passages that direct fluid toward the bottom of the borehole.

Abstract: Abstract Polluting liquids spillages especially of oil and petroleum product, are removed by applying cellulose fibre material that comprises shredded and pulverised paper to the spillage, allowing the fibre to absorb the liquid, and recovering the material containing the absorbed liquid.  The fibre material may be provided with improved fire-suppressing properties by wetting the paper with a fire-retardant solution before shredding and pulverising it so that the cellulosic fibres are substantially uniformly impregnated with the fire-retardant substances, and improved absorbency and a fluffy resilient texture and reduced density may be obtained by agitating the moist pulverised fibres in the presence of dry powdery drying and talcing agents, e.g. powdered magnesite.

Abstract: ABSTRACT OF THE DISCLOSURE     A high voltage d.c. power transmission system utilizes a metallic return conductor for carrying return current between converters at opposite ends of the system.          The return conductor is connected to ground at one end of the system and is otherwise insulated from ground so that its opposite end is floating with respect to d.c.  The return conductor has no capacitor connected from ground thereto of a size capable of limiting the voltage thereon.  But connected between said opposite end of the return conductor and ground is a valve-type surge arrestor having a primarily zinc-oxide valve element and no gap in series therewith.  This surge arrestor has a protective level that is reached by the overvoltages produced by the normal operating transients of the system, such as those produced by system start-up and commutation failures.

Abstract: ABSTRACT Developing apparatus for diazo copy sheets is provided wherein the development chamber is supplied with anhydrous ammonia gas drawn from the region above the liquid ammonia solution in a reservoir. The ammonia gas is withdrawn from the reservoir by a pump which moves it into the development chamber.  Due to the gas inflow inspired by the pump, the gas mixture in the chamber is  caused to nigrate out of the chamber by a return conduit whose outlet end is positioned below the surface of the liquid in the reservoir. The copy sheet transport means is  a roll which occupies a mouth formed in a wall of the development chamber, and means are provided for effectively sealing the chamber contact margins against the roller to prevent escape of gas therefrom.  The development chamber is arranged to snap over the roller and to be largely supported and positioned thereby.  Means are also provided for forming and maintaining a pool of water in the chamber, and a heater within the transport roll aids in vaporizing the water to aid development while also guarding against undue moisture absorption by a copy sheet being developed.

Abstract: ELECTRONIC DAMPING OF STEPPER MOTOR             ABSTRACT     A damping control system for a three phase stepper motor.  A reluctance velocity transducer is used for each of the three phases.  The output of each of the transducers is proportional to the rotational velocity of the motor. Each of the transducers is rotationally phase shifted 3.75 with respect to one another and phased to the motor rotor rotationally such that the zero voltage crossings of the transducers correspond to the zero torque crossings of the motor.  During damping or detenting of the motor the selected phase has current applied to it which is equal to a pre-determined fixed value plus the feedback from its associated transducer.  The windings on each side of the detent position have current applied to them which is proportional to the voltage from their respective feedback transducers.  The voltage in each of the windings is amplified by a selected gain constant. The current in each of the windings is such that maximum torque is applied to drive the motor to the detent position with appropriate current reversals in the windings to damp out any kinetic energy in the rotor during detenting.
