Abstract: ABSTRACT OF THE DISCLOSURE          A luggage or article carrying system for operative association with an automotive vehicle having an exterior generally horizontal surface, such as a trunk lid or roof, the system comprising a pair of elongated slats on the surface in respective positions on opposite sides of the longitudinal axis of the body and extending substantially parallel to the longitudinal axis of the body, the slats being permanently secured to the body and being substantially rectangular in the vertical cross section with a width sub-stantially greater than the height and presenting a low profile on the vehicle, the tops of the slats being substan-tially flat and parallel to the horizontal surface and providing longitudinally extending channels by which a pair of laterally extending cross slats may be secured their opposite ends to the longitudinally extending slats, the cross slats being adapted to underlie articles supported on the carrier so as to obviate the need for supplemental reinforce-ment of the vehicle trunk lid or roof, with the cross slats being longitudinally moveable or adjustable along the longitudinally extending slats and being totally removable therefrom, and a pair of transversely or laterally extending article constraining bars or rails supported at their opposite ends upon the longitudinally extending slats by means of a plurality of stanchion assemblies disposed one at each end of each of the cross bars, the stanchion assemblies and cross bars being longitudinally adjustable along the longitudinally extending slats and being removable therefrom along with the cross slats during periods of non-use.  In one embodiment of the present invention, the slats secured to the exterior surface of the vehicle extend transversely, rather than longitudinally of the vehicle, and the article constraining bars or rails extend longitudinally of the vehicle.  The cross slats, cross-bars, or rails may have attachment means thereon for securing ancillary article carrying equipment, such as ski racks, bike racks, and the like to the carrier system.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved control circuit for protecting a high voltage DC electrostatic system from arcing by removing the high voltage from the electrostatic system under incipient arcing conditions.  A signal having a voltage proportional to the instantaneous high voltage current in the electrostatic system is established.  DC components and unwanted noise and unwanted AC components are removed from the signal to leave only signal components relating to the rate of change of the current in the high voltage system and information indicative of incipient arcing conditions.  When the remaining signal exceeds a pre-determined reference level, high voltage is removed from the electrostatic system.

Abstract: ABSTRACT    MEMORY SYSTEMS         A cache memory system is described that reduces cache interference during direct memory access block write operations to main memory. A control memory 36 within cache contains in a single location validity bits for each word in a memory block.  In response to the first word transferred at the beginning of a direct memory access block write operation to main memory, all validity bits for the block are reset in a single cache cycle.  Cache is thereafter free to be read by the central processor during the time that the remaining words of the block are written without the need for additional cache invalidation memory cycles.

Abstract: PREPARATION OF HIGHLY PURIFIED HUMAN ANTIHEMOPHILIC FACTOR             Abstract of the Disclosure Highly purified, biologically active Human Antihemophilic Factor (AHF) preparations are prepared having specific activities of about 4000 - 8000 units per milligram of AHF. In the method of preparation an AHF concentrate, prepared by fractionation of plasma to partially remove fibrinogen, fibronectin and other plasma components is subjected to a separation on the basis of Stokes' radius to separate AHF from the bulk of remaining proteins in the AHF concentrate.  The pooled fractions containing AHF activity are concentrated by precipitation with ammonium sulfate , sodium sulfate, etc., by diafiltration, by PEG addition, or the like.  The concentrate, is solubilized or equilibrated in an aqueous medium and treated to change the effective Stokes' radius of the AHF to an apparently low value and then subjected to a separation from the concentrate.  The AHF pool from above is treated to remove cations by dialysis against an appropriate buffer of lower ionic strength and chromatographed on an anion-exchange medium.  The AHF fraction from the above chromatography, is a highly purified AHF preparation.

Abstract: Abstract of the Disclosure Data signals indicative of subsurface well physical measurements and t or geophysical measurements are transmitted through the drilling mud by pressure pulsations originating at a downhole apparatus.  Two closely spaced pressure sensors measure mud pressure pulsations in a mud line at a surface location.  Both of the measured pressure pulsation signals are time shifted an amount equal to the travel time of the upwardly and downwardly propagation acoustic velocity in the mud between the two pressure sensors by separate time delay circuits.  Summing circuits separately combine the original and delayed signals to cancel the respective upwardly and downwardly propagating energy from the two pressure data signals.  An estimator circuit and a deconvolution circuit process the composite signals to derive an estimated primary signal representing upward traveling energy.  The resulting pressure data signal is then processed by each of n matched filters to determine the presence or absence of one of n symbols in the residual data signal.          Each output of the filtered data signals is then input to a "Largest of" Bayesian detector to identify either the presence of a symbol or absence of the data signal.  A method is provided for recovery of data in a well logging while drilling system wherein a data signal originating from a downhole apparatus is transmitted to the earth's surface through drilling mud.  In the method, pressure wave energy in a mud flow line at the earth's surface is measured in two spatially separated locations; then at least one two-dimensional velocity selective filter which in the preferred embodiment is a velocity selective filter such as a velocity notch filter two intermediate signals representing the upward and the down-ward traveling composite pressure signals.
