Title: Flexible connector to afford adjustability in a liquid delivery line
Inventor: PARKER FRANK M
IPC: F16L27/12
Filed: 1992-07-02
Abstract: ABSTRACT OF DISCLOSURE A flexible connector is used to connect a  source of liquid to a dispenser so that the position of the dispenser may be adjusted or the line leading to a fixed dispenser may be adjusted.  A typical use is in connecting underground pipe to a sprinkler head, but the invention may be used in other installations.  Examples are to provide a connector for a light-weight, non-kink garden hose; sewer pipe fittings and ABS drain pipe. A very flexible tubing, such as light vinyl tubing, is encased in a tough outer protective tubing, such as convoluted tubing.  At either end is a fitting into which the flexible tubing fits. A bushing inside the fitting expands the end of the flexible tubing and thus retains it within the body of the fitting.  The end of the protective fitting is received in a counterbore in an end of the fitting. The upper end of the fitting may be attached to a sprinkler head or other device and hence may be shaped with an internal thread, an external thread, or a smooth cylindrical shape for a slip fit. Various nipples, pipe fittings and sprinkler head bodies may be attached to the upper end of the body.

Abstract: A received time division multiple access (TDMA) signal having a time  slot comprised of a plurality of symbols including at least one sequence of synchronizing symbols and a plurality of data symbols is demodulated by adaptively filtering  the  received  signal  to minimize  inter-symbol interference due to an effect of channel signal propagation delay.    The  adaptive  filtering  step  is  performed  by processing the received signal with a multi-stage lattice decision feedback equalizer having  (M = N1 - N2)  stages followed by (N2 - 1) two-dimensional stages.  A metric is next formed for each of the stages in accordance with a predetermined mathematical relationship between the output signals of each of two stages. A plurality of the formed metrics are next accumulated over a plurality of time slots. A number of stages are then recursively determined for the lattice decision feedback equalizer for use during the next time slot by comparing, to a threshold value, the difference between the values of two accumulated metrics.
