Abstract: PATENT APPLICATION        of GEORGE D. KNEIP, JR. AND MARVIN H. ANDERSON                      for IMPROVED CRYOSTAT WITH EXTERNAL REFRIGERATOR             FOR SUPERCONDUCTING NMR SPECTROMETER        Abstract of Disclosure An improved cryostat for the superconducting magnet of an NMR spectrometer comprises a nested structure of isothermal shells surrounding a thermally conductive central reservoir of substantially spherical shape containing liquid helium in which the superconducting solenoid remains operational when only partially immersed.  A radiation shield surrounding the central reservoir is cooled by the boil-off of escaping helium vapor.  The radiation shield is enclosed within an isothermal shell maintained at the temperature of liquid nitrogen by thermal contact with a liquid nitrogen reservoir disposed above the region of the central reservoir and shielded therefrom by a wall of the isothermal shell.  An outer radiation shield surround the liquid nitrogen reservoir and associated isothermal shell and the outer radiation shield is maintained at a temperature of the order of 180° K by an external refrigeration facility.  A hermitically sealed containment vessel forms the outer wall of the cryostat and provides a port for evacuating to a vary low common pressure all the interior spaces between adjacent nested structures.  The spacing between adjacent nested surfaces is maintained by a novel internal mechanical bracing system of low thermal conductivity comprising polyester cords disposed under tension between adjacent shells.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a novel control and method for maintaining optimum performance and power transfer through HVDC power transmission systems during A. C. system faults affecting the rectifier end of the system.  In particular, there is provided a novel control for HVDC power converters of the type normally employing equidistant-spaced firing pulses.          The control senses the occurrence of a nearby single phase fault in a multiphase A.C. supply system supplying voltage across HVDC thyristors of such a power converter, which fault results in an advance of the phase of certain of the phase voltages and a retardation of the phase of other of the phase voltages.  The control derives control signals for delaying the firing (gating-on) of these thysistors whose A.C. supply phase voltages are retarded and advancing the firing of those thyrsitors whose phase voltages are advanced thereby assuring that at all times adequate voltage exists across all the thyristors to assure safe turn-on and commutation off of the thyristors while at the same time assuring maximum power transfer through the HVDC pwoer transmission system even in the presence of severe A.C. system faults.

Abstract: SPIN ACTIVATED SAFETY                   PAUL J. SENGSTOCK, JR. CIRCUIT FOR SPACECRAFT         GERALD L. DUTCHER                 ABSTRACT OF THE DISCLOSURE       A spacecraft specifically adapted for launch from the space shuttle by means of a cradle having locking and ejection mechanisms mounted therein.  The cradle fastens into the payload bay of the space shuttle and returns therewith for reuse in subsequent launches.  The spacecraft mounts at three points to the cradle, and the cradle mounts at three points to the shuttle such that a plane through the attachment points passes through the roll axis of the spacecraft at approximately the center of mass thereof.  The cradle utilizes the truss structure of the spacecraft to produce the required stiffness by providing a structural tie between the two ends and the bottom of the cradle.          At launch, the spacecraft is ejected with both linear and angular momentum, the spin providing gyroscopic stability.  The locking mechanisms in the cradle can be remotely controlled to relock the spacecraft to the cradle in the event of an unsuccessful deployment attempt.  The spacecraft includes a safety circuit employing acceleration sensing switches which sense spin-up of the spacecraft and prevent premature ignition of the perigee boost motor.  The spacecraft has imbedded within its envelope a solid-propellant perigee boost motor surrounded by a liquid-propellant apogee motor. By employing apogee and perigee propulsion stages internal to the spacecraft, the storage length in the space shuttle is minimized, and the geometry and mass characteristics of the spacecraft make for a stable spinning vehicle during both the perigee and apogee boost phases.

Abstract: ROTARY PROCESSING APPARATUS            Abstract of the Disclosure This apparatus comprises a supporting frame for two upstanding chutes through which flowable, particulate materials may be applied.  These materials flow down the chutes through an opening in the top skirt plate supported by the frame and into a processing area such as the rotor of a centrifugal impact milling machine.  A motor is mounted for horizontal pivotal movement relative to the chutes and drives a vertical spindle located between the chutes that is connected to the rotary processing member below the skirt such as the rotor of a centrifugal impact machine.  A hopper is provided to swing pivotally downward below the rotor in a damped fashion, the pivoting mechanism being fixed to the top skirt and enabling one man removability of the hopper to allow access to the rotor or the inside of the hopper for cleaning, maintenance, etc.  A single man, by pulling up on the hopper and abetted by the upward-biasing effect of a gas spring component of the pivoting mechanism, can remount the hopper in its normal fixed position.  Provision is made for easy withdrawal of the shaft or spindle assembly from the top after the rotor has been detached therefrom. The shaft or spindle assembly also includes at its lower end an easily removable seal cartridge that can be extracted from below by appropriate extraction tools engaging passageways in the cartridge after a transverse retaining pin, accessible from the outside of the spindle housing, is pulled out from engagement with a corresponding retaining channel in the seal cartridge itself.

Abstract: PHN 9502                   11                    4.4.1980 ABSTRACT: Shaving apparatus.     The invention relates to a shaving apparatus having an external first cutting element and an internal second cutting element which cooperates with said first element, which second element is drivable relative to the other cutting element with a reciprocating movement. In a known apparatus the first cutting element takes the form of a foil formed with apertures, and the second driven cutting element is urged against the inner side of the foil by-means of springs. A drawback of this construction is that as a result of forces occurring during shaving the foil is deformed or the driven cutting element is urged away from the foil, so that the distance between the two becomes too large for a satisfactory cutting action. This drawback is eliminated in the present invention by means of a construction in which the drivable cutting element is secured to the other cutting element by means of a connecting element which is flexible in the direction of driving  and is rigid in directions extending substantially transversely of the direction of driving.

Abstract: ABSTRACT OF THE DISCLOSURE           Timing errors in a color television signal equal to a fraction of the nominal period of one cycle of color burst are corrected by clocking an analog-to-digital converter during each horizontal line interval of the television signal with two clock signals having the same nominal frequency equal to a multiple of that of the color burst.  During the color burst interval of each horizontal line, the analog-to-digital converter is clocked by a stable time base reference clock signal and the obtained digitized color burst is stored in a recyclable digital memory.  Following the color burst interval, the stored digitized color burst is regenerated for the remainder of the horizontal line and a clock signal derived for use in clocking the analog-to-digital converter.  The digitized television signal provided by the analog-to-digital converter is written into a clock isolator at times determined by the clock signal derived from the digitized color burst and, thereafter, read from the clock isolator at times determined by the reference clock signal.  Timing errors exceeding the nominal period of one color burst cycle are corrected by writing the digitized television signal from the clock isolator into a following random access memory and incrementally adjusting the memory's read time in accordance with such errors measured in steps equal to the period of one color burst cycle.          The stable time base reference clock signal is coupled to control the signal processing following passage through the clock isolator.

Abstract: A Variable Energy Standing Wave Linear Accelerator Structure Abstract Variable energy selection is accomplished in a side cavity coupled standing wave linear accelerator by shifting the phase of the field in a selected side coupling cavity by .pi. radians where such side coupling cavity is disposed intermediate groups of accelerating cavities.  For an average acceleration energy of E1 (MeV) per interaction cavity, and a total number of N interaction cavities, the total energy gain is El (N-2N1 ) where N1 is the number of interaction cavities traversed beyond the incidence of the phase shift.  The phase shift is most simply accomplished by changing the selected side cavity configuration mechanically in repeatable manner so that its resonant excitation is switched from TM010 mode to either TM011 or TEM modes.  Thus, the total energy gain can be varied without changing the RF input power.  In addition, the beam energy spread is unaffected.

Abstract: A RETROREFLECTOR PLATE AND A METHOD FOR ITS MANUFACTURE     Abstract A retroreflector plate and a method for its manufacture are described.            The retroreflector plates consist of a trans-parent plate with a reflective rear side, the front side of which comprises adjacently disposed, curved light incidence surfaces, and the rear side of which comprises adjacently disposed, curved reflection surfaces, in which case the optical axis of each individual light incidence surface coincides with the optical axis of a respective reflection surface.            The retroreflector plates are distinguished by the fact that, when the light incidence surfaces or the reflection surfaces are projected perpendicular and parallel onto the plate surface, as the plane of hori-zontal projection, the outlines of the reflection surfaces comprise different surface content, when compared with each other and with the light incidence surfaces, or, the outlines of the light incidence surfaces and their respective reflection surfaces substantially comprise the same surface content, while having different contour shapes.            The retroreflector plates are further distin-guished by the highest possible luminous values and at the same time by a wide angle range of reflection.

Abstract: Case 135?/1358 ABSTRACT OF THE DISCLOSURE        Method and apparatus for pressurized fluid stream treatment of the surface of a relatively moving substrate to impart visual surface changes thereto.  The apparatus includes a fluid discharge manifold comprising an elongate compartment with discharge slot disposed across the path of relative movement of the substrate to discharge pressurized heated fluid, such as air, in one or more narrow discrete streams into the surface of a substrate, such as a textile, fabric.  A plurality of spaced, cooler air out-lets are disposed in the discharge slot of the manifold, and pressurized cooler air is select-ively directed through the outlets and across the slot in accordance with pattern information to block the heated air streams from exiting from the discharge slot in selected locations and thus pattern the surface of the web.  Associated with each of a plurality of inlet conduits is a separate heater unit and temperature sensing means, as well as an individual metering valve, for heating and adjusting the flow of pressur-ized fluid passing into the manifold.  The indi-vidual metering valves are adjusted to balance the temperature of the heated fluid exiting from the inlet conduits into the manifold.  A single temperature sensing device, located in the mani-fold, may then be used to adjust a uniform supply of power to all heater units, thereby maintaining a desired fluid temperature in the manifold.      The invention further includes means for supplying a heat transfer fluid to the interior of a rotatable roll employed to support the sub-strate during its passage by the heated fluid distributing manifold.      The heated pressurized streams of air striking the surface of a thermoplastic yarn or fiber containing textile fabric causes thermal modification and longitudinal shrinkage of thermoplastic yarn and fiber components therein to provide the patterned appearance to the fabric surface.  Also specifically disclosed are novel textile pile fabrics having patterned surface effects therein, and thermoplastic textile woven fabrics which are treated with the heated stream or streams to provide a crepe or pucker appear-ance in the fabric.
