Abstract: ABSTRACT OF THE DISCLOSURE:           A threaded connection integrally provided with an anti-unthreading lock, which comprises a first externally threaded connector, a second internally threaded connector, these two threaded connectors being constructed to be threadedly con-nected together until tight, and at such time to have a surface portion of one of the connectors facially juxtaposed with an angularly elongated slot formed in a marginal portion of the other of the connectors, near but spaced from an edge surface of the latter. The slot is bounded by a perimetrical surface, a recess in the surface portion, the recess opening toward the other connector between said slot and the edge surface and having a first radially extending, angularly facing stop shoulder.  The marginal portion of the other connector between the slot and the edge surface is constructed and arranged to be field-sheared crosswise to form a lock tongue bounded by the perimetrical surface of the slot, by the edge surface and by a sheared end surface, providing a second angularly facing stop shoulder, and to have such locking tongue then deformed into the recess and the first and second stop shoulders thereby into locking engagement.

Abstract: ABSTRACT OF THE DISCLOSURE       A swivel hook assembly for attachment to a carrying strap of a bag, for example, includes a connector, an elongate support rotatably mounted on the connector, and a hook mounted on the elongate support.  The connector, the support and the hook are all molded of synthetic resin.          The hook has a head rotatably fitted in a central hole defined in the support and locked against removal therefrom.  The connector and the support are simultaneously molded in a single step of molding operation in an assembled condition.  The hook may be molded integrally with the support.  The swivel hook assembly is composed of a relatively reduced number of parts, can be assembled easily and less costly, and may be colored to meet user's various preferences for fasionable color combinations.

Abstract: COMMUNICATION NETWORK     Abstract A high-speed fiber optic star configuration network uses a processor at the network hub to monitor and control network activity.  The hub and the individual nodes of the network cooperate to calibrate node transmitter power levels and node receiver sensitivities.  A token passing protocol is used to allocate network access.  The token passing is monitored at the hub to detect lost tokens or a babbling bus.  The hub processor has the capability to initiate tokens or restore lost tokens and to shut off the transmitter of a node which remains connected to the bus for an excessive period of time.  In one embodiment, the circuit elements of the hub are duplicated to provide two separate paths through the hub.

Abstract: SHAPE FORMING AND QUILTING - APPARATUS AND METHOD     Abstract of the Disclosure The machine includes a stationary bridge frame having a sewing head mounted thereon, an upper carriage which carries the quilt, and a lower carriage.  The lower carriage rides on track rails on the floor running in one direction, and the upper carriage rides on track rails on the lower carriage running in transverse direction.  A drive unit is mounted on the upper carriage and has a drive wheel engaging the floor.  The drive is produced by running the drive wheel, and rotating the drive unit about a vertical axis, to trace out a pre-designed pattern.  The drive wheel can be driven forward, stopped, and reversed.  The drive wheel is driven a constant speed, and different kinds of elements of the pattern are produced by turning the drive unit a lesser or greater amount about its vertical axis.  A computer unit is utilized, and instructions entered thereinto to turn the drive unit about its vertical axis at predetermined points.  In that operation the drive wheel engages a flat surface board, without tracks, but it is also adaptable to use with tracks, alternatively, and in the latter case, the computer unit is de-energized.  The construction and arrangement includes alternatively a complete quilting machine or an attachment that can be added in a pre-existing machine.

Abstract: HIGH SPEED HOT AIR LEAK SENSOR                 Abstract of the Disclosure A hot air leak sensor for sensing jet engine bleed air leaks in an aircraft.  Infrared detectors are combined with thermal re-radiating elements which are installed in air passages adjacent to the bleed air ducts and downstream of the region where a bleed air leak may occur.          The elements are approximately 50% transmissive and 50% absorptive to infrared radiation with wavelengths within the range of approximately 4 to 20 micrometers.  Incident radiation within the field of view of the detector is both transmitted and absorbed for re-radiation to the detector.          If no incident radiation within the sensor field of view is available, the re-radiating element still responds to the increased airstream temperature resulting from the bleed air leak and supplies radiation to the detector to provide detection of the leak.

Abstract: ABSTRACT OF THE DISCLOSURE    A high speed memory access circuit of a CRT display unit generates address signals from a memory cycle controller (20) based on an external write signal provided from the exterior and supplies the address signals to a frame memory (8) structured by dynamic random access memories (81 to 86).  The frame memory (8) reads out, based on the address signals, the first and the second data in parallel, each data being divided into odd number region data and even number region data.  The odd number region data and even number region data of the first data are provided in series through shift registers (313, 323), respectively and the odd number region data and even number region data of the second data are provided in series through shift registers (314, 324), respectively.          Thus, the first and the second data read out from the frame memory (8) are provided in series respectively in the form divided into odd number data and even number data and accordingly, it is made possible to employ shift registers of relatively low speed even in case a pattern of a high resolution is displayed by using a non-interlace CRT display unit of 60 Hz.
