Abstract: APERIODIC ANALYSIS SYSTEM, AS FOR THE ELECTROENCEPHALOGRAM           Abstract of the Disclosure An aperiodic signal is preliminarily processed by an active network (34) to provide three relatively separate components that include:  slow waves (waveform cycles or fragments of equivalent frequency from 1 to 8 hertz), fast waves (waveform cycles or fragments of equivalent frequency from 8 to 30 hertz), and a signal component which may contain spikes (fast, large, sharp single waves).  The component signals or waves are applied to individual detector circuits (42, 44, and 46) which indicate amplitude and period (or equivalent frequency) information for detected waves and the ampli-tude for recognized spikes, as well as the time of their occurrence.  Detected waves (including spikes) produce representative trigger signals which are applied through a multiplexer (50) to a storage device (16), specifically a cathode ray tube (18) on which the waves and spikes are representatively displayed and stored to complete a static picture which indicates an interval of the waveform.  As disclosed, a representation or picture is generated on the storage tube (18) by controlling the horizontal and vertical amplifiers and appropriately blanking the beam to develop a composite display that summarizes many seconds of the aperiodic signal. The display (FIGURE 2) is a three-dimensional representation with each wave represented by a line (24, 26, 28, 30, or 32) that extends in one dimension to indicate amplitude The position of the line in another dimension indicates the period or equivalent frequency, and its position in the third dimension indicates the time of occurrence of the wave.

Abstract: ABSTRACT       A strapping machine for binding packages with metal or plastics strapping has a tensioning device which is driven by an electric motor more instead of the more usual air motor.  The electric motor is coupled to the tensioning  device by  a  hydro-dynamic  coupling which delivers  maximum  torque with its  output stalled but while  its  input is still rotating and such that the motor  is  not overloaded  even though the  tension is maintained for an appreciable time.  The maximum output of the hydro-dynamic coupling can be adjusted by alter-ing the quantity of hydraulic fluid it contains either initially or by a fluid control circuit which causes fluid to flow into or out of the working chamber of the coupling to alter the amount of fluid it contains.

Abstract: ABSTRACT OF THE DISCLOSURE     A novel synthetic yarn is disclosed which com-prises fibers of different lengths (as specified).  At least three groups of synthetic fibers are present in the yarn, with the synthetic fibers within each group being substantially uniform in length.  The substantially uniform, length of each group of synthetic fibers present in the yarn differs from the substantially uniform length of the syn-thetic fibers in the other groups.  The use of such mixtures of fiber lengths in a synthetic yarn enables the yarn to exhibit physical characteristics such as high bulk which more closely resemble the characteristics of natural fiber-containing yarns.  Fabrics having improved physical charac-teristics may also be produced from the novel synthetic yarns disclosed.
