Abstract: MESH STRUCTURE AND LAMINATE MADE THEREWITH.          Abstract In order to produce a biaxially orientated mesh structure using a single axis draw, a plastics material starting material has parallel, side-by-side main zones separated by lines of holes or depressions: the starting material is drawn parallel to the main zones, stretching the main zones into continuous, orientated main strands   interconnected by smaller cross-section strands   which have been formed from the zones between holes or depressions in each line, and have been orientated at right angles to the direction of drawing by the effect of the main zones decreasing in width as they were stretched.  The mesh structure is suitable for cross-lamination.

Abstract: ABSTRACT Method and Apparatus for Automatically setting the demand phase lag input to an induction-motor power factor controller Motor  power-factor controllers (12) act, in the presence of varying motor loads, to maintain the phase lag angle (0M) between motor voltage and current at a preset demand or reference phase-lag value  (0R) by regulating the firing angle of gate-controlled switching devices (11) connected in series with the motor supply (A, B,C).  The optimum reference phase-lag value (0R) depends on the motor characteristics and will be  as small as possible while providing for a stable, unambiguous control characteristic.  A reference-setting unit (14) is provided for automatically setting an appropriate reference phase lag (0R).  This unit (14) monitors the motor phase lag (0M) during start up and sets the reference phase lag (0R) to a value corresponding to the minimum monitored phase lag plus a predetermined amount (for example 8°).  The unit (14) can be arranged to seek to improve on the set reference (0R) during motor running by repeatedly comparing the actual phase lag (0M) plus said predetermined amount, with the set reference (0R) and resetting the latter to the former if this has a lesser value.

Abstract: IMPROVED PIPE FLUSHING DEVICE                ABSTRACT OF THE DISCLOSURE           The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure.  The rear inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion.  The valve has a cage bearing a rear plate closure, and open sides and front.  The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate.  The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state.  However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving rearwardly in the groove to cause a mechanical vibration in the tubular member and water pipe.  Water then by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog.  Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe.  The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vibrate the pipe to unclog the pipe.
