Abstract: ABSTRACT OF THE DISCLOSURE          A low-mass, short loop transport wherein the span of tape passing the inter-leaved head assembly is close-coupled and unsupported, with the turn-around points for the tape being at the beginning and end of the span in either direction of travel, thereby reducing head wear, skew, flutter and other undersirable characteristics.  The tape is passed from the supply reel through a vacuum tensioning chamber over a pair of relatively large diameter low-mass drums defining the span or section of tape adjacent the head assembly to a second vacuum tensioning chamber and thence to the take-up reel.  The drums are directly driven by peripheral contact with a capstan in both the record/read mode and the fast transport lift mode of operation.  The drums may be mounted on movable eccentric shafts so that their axes of rotation can be shifted in a small arc carrying the drums in a manner to bring the  span of the tape into sequential contact with the array of transducers in the head assembly or carry the drums and span of tape away from the head assembly in the lift mode of operation.

Abstract: ABSTRACT OF THE DISCLOSURE            A hydraulic end of car cushioning device for use in railway freight cars.  The device is intended for use between the coupler shank and car under-frame of a fixed sill type car and is designed so as to provide a long cushioning stroke under high impact loads.  A load responsive check valve is interposed in the metering system of the cushioning device for preventing changes in length of the unit under lower buff and draft forces as occur in train action.  More specifically there is provided a cylinder with a piston received in the cylinder and the piston and cylinder defining a chamber adapted to receive fluid.  A primary metering device includes an orifice and a cooperating metering rod, the device being in communication with the chamber for passing fluid therethrough at a restricted rate upon relative movement of the piston and the cylinder.          A pressure responsive valve is provided in series flow arrangement with the primary metering device for precluding the flow of fluid through the primary metering device until a predetermined force is applied to the cushioning device.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of manufacturing a device for use in the treatment of fluid and in particular a supported catalyst for motor vehicle exhaust gas purification.  For this, short lengths of wire of an aluminium containing iron based alloy with a smooth surface free from edges or sharp corners are wound into helical coil components in which contact between adjacent turns of the wire in the helical coil is avoided.  The helical coil components are contacted with a dispersion in a liquid medium of a refractory material and a catalytic material.  Excess liquid is removed by shaking  followed by drying and firing and assembling the components in a container having inlet and outlet gas passageways.

Abstract: MASS TRANSFER DEVICE Abstract of the Disclosure A mass transfer device consists of a stack of alternating plates and membranes in which each plate in-cludes on each surface two manifolds for distributing and collecting fluid transversely of the plate.  Headers inter-connect to distribute and collect fluid uniformly to and from each plate.  Inlet and outlet manifold channels of each plate surface are connected by channels formed in the central portion of the plate.  Mass transfer occurs across the membrane supported between adjacent plates with a first fluid on one side and a second fluid on the other side.  Substantially uniform inter- and intra-plate fluid distribution and thin fluid films enhance mass transfer.  The device, with slight alternations appropriate to the application, is useful for dialysis, hemodialysis, blood oxygenation, reverse osmosis, heat exchange, or gas scrubbing.

Abstract: Abstract of the Disclosure The flow rate of the absorption medium entering an absorption column and the flow rate of steam into a reboiler associated with a stripping column are controlled in response to the flow rate of a feed stream into the absorp-tion column, the concentration of impurities in the feed stream, and the flow rate of the absorption medium containing the impurity removed from the feed-stream into the stripping column in such a manner that the efficiency of the absorption process is optimized.  A computer system is utilized to simulate the flow of materials inside the absorption and stripping columns.  Feed forwardcontrol, based on the simulations, is utilized to maximize the energy effi-ciency of the absorption/stripping process by reducing the amount of steam required by the  stripping process and reducing energy consumption of the pumping system utilized to return the absorption medium to the absorption column.

Abstract: ABSTRACT OF THE DISCLOSURE             This disclosure relates to a new self-locking threaded fastener means having a patch on the threaded portion thereof to provide self-locking properties.  The patch may be comprised of a thermoplastic polymer such as a thermoplastic epoxy ad-hesive system and is applied to the threaded fastener in an unpolymerized state and is allowed to polymerize in situ.  Since an unpolymerized adhesive composition would be applied as a liquid, it would not be necessary to heat the fastener, thus saving valuable energy as well as eliminating the chance of destroying any corrosion resistant coating on the fastener such as phosphate and oil.  This new fastener means also has good multiple usage characteristics in that it may be installed and removed several times without losing its self-locking properties.

Abstract: ABSTRACT         The present invention is directed generally to electrical connection assemblies and, more particularly, to an assembly for terminating a flat electrical cable having a plurality of electrical transmission or signal conductors and ground conductors arranged in a closely-spaced array within a strip of insulative material.          Prior art termination assemblies suffer from the dis-advantage that they are not suitable for use with cable having very closely spaced conductors.  When the conductors are spaced at intervals of about 0.030 inch or less, conventional insulation-piercing termination devices are susceptible to shorting which is, of course, unacceptable.          The present invention therefore, is directed to a mass termination system for flat cable having very closely spaced con-ductors which overcomes the problems and disadvantages associated with prior art devices.  The assembly of the present invention includes connector means to terminate selected conductors, isolation means to inactivate certain other selected conductors at the locus of the termination and bridging means to electrically couple the inactivated conductors to the connector means.  The assembly allows the use of in-sulation-piercing termination devices without the danger of shorting between the closely spaced adjacent conductors.

Abstract: Abstract The planar transmission line attenuator and switch is formed on a semiconductor substrate consisting of a high resistivity semiconductor material and a thin, conductive semiconductor layer. Transmission line metallic conductors are deposited on the conductive semiconductor layer, and at least one of the metallic conductors forms a Schottky barrier contact to the semiconductor substrate.  The gap between the metallic conductors defines a shunt current path through the semiconductor layer.  By applying a bias voltage to the metallic conductor forming the Schottky barrier contact, the conductivity of the shunt path can be controlled by changing the depletion layer width across the Schottky barrier.  A plurality of planar transmission line switches can be combined into multi-port networks, examples of which are cross-bar switching devices and .beta. element switching devices.

Each possible combination of the comparison result, within the range of possible phase argument values of the analog signal, has correlated therewith a respective zone, whereby there is formed a coarse interpolation of a period of the analog signal into phase zones.  The components are digitized and there are selected the components having the smallest (X), the intermediate (Y) and the largest (Z) absolute value.  There are formed the digital functions H = Y - X and K = Z-Y + X.  Each possible combination (H, K) is correlated to a respective predetermined number of steps of the phase argument within the zone,  Thereby producing a fine interpolation of the zone into steps.      Preferably, at the beginning there is subtracted from each analog component one-third of the sum of the three components.
