Abstract: EXCITATION LEAD FOR SUPERCONDUCTING    DEVICES, PARTICULARLY MAGNETS              ABSTRACT OF THE DISCLOSURE      When it is desired to change the magnetic field levels in a superconducting magnet, it is conventional practice to employ electrical leads.  One end of the leads is maintained at cryogenic temperatures while the other is at ambient temperature.  In some cases, it is desirable to remove the leads when they are not being used, in order to reduce thermal losses.  In that case, it is conventional practice to make and break the contact at the cryogenic temperature.  However, repeated make and break contacts with such a lead can produce worn contact surfaces that eventually exhibit a higher resistance than is desired.  This high resistance will give rise to heating of the cryogenic components.  In order to alleviate this problem, an excitation lead system is provided which is removable from the cryostat. Furthermore, thermal insulation means are provided so that the external connection is relatively warm when the leads are connected, but is maintained at relatively cold temperatures during normal operation of the super-conducting device.  The fact that the contact is relatively warm when the lead is in use relaxes the requirement for a low resistance contact.

Abstract: PREPARATION OF AMINO POLYOLS        ABSTRACT         An improved method is disclosed for producing amino polyols useful in preparing polyurethane foams.  The improvement concerns charging ammonia, a primary amine or a secondary amine to the reaction vessel at the end of the oxide digestion step.  The amine or ammonia scavenges the residual oxide and the resulting alkanol amine becomes one of the components of the polyol mixture.  Alkanol amines are beneficial components of urethane polyols.         In prior art industrial practice, residual oxide is vented to a scrubber system and then stripped to a low concentration.

Abstract: Abstract of the Disclosure A heater is disclosed having an elongate wire heating element with the heating element including at least two generally parallel runs supported on a frame by insulators with the portion of the heating element constituting the runs being formed generally in a helical coil and with the portion of the heating element between the runs being referred to as a turnaround.          Specifically, the turnarounds are of non-helical coil construction and have at least one loop therein between the insulators supporting adjacent runs of the heating element thereby to permit limited movement between the adjacent runs and to permit thermal expansion and contraction of the turnarounds without applying a substantial force to the insulators.  Further, the insulators are constructed so as to engage three convolutions of the coiled helical heating element runs with the intermediate engaged coil convolution being resiliently deflected inwardly toward the central longitudinal axis of the helical coil thereby to aid in resiliently retaining the run of the heating element on the insulator.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure relates to an electric buffing machine which is equipped with an X-shaped buffing pad that is mounted to a similarly X shaped pad holder.  The arms of the pad holder have a wedge-shaped cross section that acts as an air foil to create air currents that flow up between the arms of the X-pad.  The casing surrounding the pad has a specially designed tunnel-like spiral diffuser that guides the air currents entered into a collection box.  The casing also has a flexible skirt mounted to the lower side thereof, extending around three-quarters of the casing periphery, which closes the gap between the casing and the floor.  The chassis has two pairs of wheels and is designed so that when the buffing machine is turned off, the machine rests entirely on the wheels with the buffing pad raised off the ground. When the machine is turned on, the air currents pull the pad to the floor with a predetermined pressure.

Abstract: ABSTRACT      The invention is drawn to a mixing pump which can transport and effectively mix (homogenize) two or more liquids (or gases) in all ratios between the pure components.  The ratio is constant, but is adjustable.  This is effected by a double-acting pump cylinder (or two coupled, single-acting cylinders) which produces a charge of the mixture in a two-stroke-cycle.  During the 1st stroke liquid (V1) is pumped from one side of the piston (2) through a restriction (12) (pressure drop) into the liquid (V2), while the liquid (V2) is sucked into the cylinder on the other side of the piston.  During the 2nd stroke the mixture (V1 + V2) is pumped to a storage tank through a restriction (13) (pressure drop), while the liquid (V1) is sucked into the cylinder.  By adjusting (by regulator 6), the amount of the liquid (V1) pumped into the liquid (V2), the pump can deliver any ratio of the two components.  By choosing the velocity of the piston and of the coefficient of resistance of the restrictions, the necessary pressure drops for every purpose can be obtained.

Abstract: Abstract The invention provides a method for producing a glass preform for an optical fiber comprising flame hydrolyzing a glass raw material in an oxyhydrogen flame to form fine glass particles, depositing the fine glass particles on a seed member to produce a solid or hollow cylindrical soot preform, dehydrating the soot preform by holding the whole preform in an atmosphere containing a dehydrating agent kept at such a temperature for such a period of time that the diameter of the soot preform shrinks by at least 20 %, and then heating and sintering the dehydrated soot preform by introducing it from one end into an atmosphere of a pure inert gas to produce a glass preform having a uniform dis-tribution of refractive index along its entire length. From such a glass preform, an optical fiber having an attenuation of light transmission as low as 1 dB/km or less at a wavelength of 1.30 micrometer can be fabricated.
