Abstract: An improved hydraulic reflector is provided for use as an antenna or solar reflector or the like, wherein the reflector is collapsible for highly compact stowage within a space vehicle and for convenient deployment in space to an expanded, generally dish-shaped configuration. The reflector comprises a rigid central dish hinged to a peripheral array of hingedly interconnected rigid panels which in turn carry a peripheral array of outwardly radiating extension ribs supporting an outer ring of flexible reflector material. The rigid panels and the extension ribs are movable together between a collapsed state folded substantially into a cylindrical envelope defined by the diametric size of the rigid central dish and a deployed configuration lying generally within a surface of revolution common to the central dish, such as a paraboloid surface in the case of an antenna.

Abstract: An improved technique for removing line tilt and other types of line rate correlated noise interjected into the active portions of a video signal during transmission and reception of the video signal. The improved technique involves measuring the amplitude of the line rate correlated noise in a received video signal at points sampled across the active portions of a plurality of lines in the video signal. The video lines used for measurement are preferably constant-amplitude dummy video lines inserted into the video signal at the bottom of each video field prior to transmission of the video signal. A complementary line-rate-correlated noise waveform, based on the amplitude measurements, is then generated and summed with the active portions of the received video signal to remove the line rate correlated noise from the video signal.

Abstract: A radio-frequency (rf) power combiner or divider structure containing distributed amplifier components and having broadband operating characteristics, and operable with net gain or practically no insertion losses. The divider structure includes an input transmission line having series-connected impedances that interconnect with active devices, such as field-effect transistors to form a practically lossless line. The active devices provide gain between distributed points in the input transmission line and distributed points in multiple output transmission lines, which are similarly structured as series-connected impedances. Each output transmission line supplies one of the divider outputs. In the combiner form of the device, there is a single output transmission line and multiple input transmission lines, coupled to the output line in a distributed manner by active devices.

The moving body includes portions devoid of ferromagnetic material, which causes a change in the magnetic field.

Abstract: An optical fiber is scored for severing by placing the fiber on a pad in contact with a surface of the pad and engaging the fiber with a scoring body having a rounded obtuse scoring surface in such manner as to urge said scoring surface into scoring contact with fiber and score the fiber without rotation of the fiber about its longitudinal axis relative to the scoring surface, whereby the scoring contact creates a local flaw in the fiber at which the fiber may be parted by stressing the fiber in tension. The scoring surface of the body is rounded to a curvature such that parting of the fiber at the flaw by stressing of the fiber in tension produces mirror smooth fiber end surfaces at the part. The scoring body may be a blade having a blunt edge providing the obtuse scoring surface or a filament such as an optical fiber positioned across the fiber between the pad and a second pad that are moved together to grip the fiber and simultaneously urge the filament into scoring contact with the fiber.

The apparatus includes an update capturing module installed at each of the computer systems, for capturing update transactions involving shared data entities, and a central data translator, which receives the updates from the update capturing modules, translates the updates into appropriate record formats and data base schemas, and transmits the translated replicas to the appropriate separate computer systems, where the updates are directly or indirectly entered into the corresponding data bases, thereby ensuring consistency among the separate but related data bases.

Abstract: A method and apparatus for modulating and demodulating a digitized stereo audio signal with a 3-level, partial response waveform. The 3-level, partial response waveform utilizes 3-level coded pulses rather than conventional on-off or 2-level coded pulses. This results in a bandwidth reduction of approximately 50% over the conventional 2-level coded pulses and allows the stereo audio signal to be transmitted within the bandwidth limitations of conventional television transmission systems, without first compressing or reducing the sampling rate of the stereo audio signal. For transmission over statellite-based systems, the modulated stereo audio signal is digitally up-converted to a 6.6 MHz quadrature subcarrier. For transmission over ground-based systems, the modulated audio signal is multiplexed into the video signal during the video horizontal blanking interval.

Abstract: This invention relates to electrical connectors and more particularly to electrical connectors for propagation of a relatively large number of signals between electrical circuits and at very high velocities. The number of signals which can be propagated is quite large in relation to the size of the connectors of the invention and at the same time, the signals can be transmitted at very high velocity and with minimal interference between the signals propagated or from external signal sources. The connectors are also advantageous in that the electrical characteristics of the propagation paths are uniform and they can be readily matched to the characteristics of the circuits which are interconnected so as to minimize standing wave phenomena. The invention also facilitates connection to a plurality of circuit board circuits while providing substantially complete separation of signals propagated to and from the circuits.

Abstract: An improved liner for a shaped explosive charge has a metal side wall with an outer side surface which is adapted to be engaged by the explosive charge and an inner side surface which defines an outwardly flaring cavity. The side wall is formed of a single crystal of metal and is free of grain boundaries. The single crystal of metal is composed of atoms arranged as unit cells all having the same orientation relative to the central axis of the cavity. This tends to optimize the performance of the shaped charge and allows the designer of the shaped charged freedom to completely specify the crystallographic orientation of the side wall of the liner.

Abstract: In order to improve the results which are obtained during the forging of a workpiece, the workpiece is electrophoretically coated with a lubricant formed of glass particles having two distinct formulations. Thus, soft glass particles having a formulation which results in transformation of the glass particles from a solid to a liquid at a relatively low temperature are interspersed with hard glass particles having a formulation which results in transformation of the glass particles from a solid to a liquid at a relatively high temperature. At the relatively high temperature, the materials of the hard and soft melted glass particles combine to form a combined glass lubricant which has a desired viscosity and lubricity at forging temperatures. This enables the soft glass particles to melt at a relatively low temperature and form an oxidation barrier around the workpiece in early stages of a preheat cycle.
