Abstract: ABSTRACT OF THE DISCLOSURE     An improved method and apparatus for measuring the length of an open pipe includes a sound transducer placed in spaced open air communication with the interior of the pipe at a selected end.  A logic circuit is employed with the transducer for producing a square wave sound pulse that is directed at the pipe's selected end.  An oscillator provides an ambient temperature modified count in accordance with the time required for the pulse to travel the length of the pipe and return.          For compensating for error tending to be introduced because of the spacing of the impedance reflective surface at the far end of the pipe, a standoff device establishes such a distance between the transducer and the selected end of the pipe as to effect an adjustment in the duration of the oscillator count that corrects for the error.  In another embodiment a microprocessor is employed with the transducer to produce two successive square wave sound pulses to effect an adjustment in the count of an oscillator clock to avoid a false reading due to the above-mentioned spacing of the reflective surface.  The amplitude of the greatest peak of the first pulse is measured.  The gain of an amplifier is then adjusted to make a timer stop, modified in accordance with ambient temperature, during the reception of the echo from the second pulse when 40% of the amplitude of the peak echo is obtained.

Abstract: - 3? -"Optical Time-Division Switching System Employing Optical Bistable Devices"                        ABSTRACT       In an optical time-division switching system, time-division multiplexed calling and called station signals are arranged in incoming time slots and applied through an incoming common optical medium to a first optical switching circuit that switches the signals to optical bistable devices in which the signals are stored as binary 1's or 0's.  A second optical switching circuit is coupled to the bistable devices for reading the stored calling station signal in the time slot of the called station and reading the stored called station signal in the time slot of the calling station to rearrange the signals in outgoing time slots.  The signals in the outgoing time slots are applied through an outgoing common optical medium to a time-division demultilexer which sequentially distributes the signals to the calling and called stations.

Abstract: Abstract It is known that the human influenza virus strain A/Puerto Rico/8/34 grows particularly well in eggs and that reassorted viruses having it as a parent may also grow well in eggs. It has now been found that certain reassortants of A/PR/8/34 and equine influenza viruses, namely those which comprise the RNA7 segment from A/PR/8/34, will grow in cell culture, even though the parent equine influenza virus will not.   Thus the specification describes and claims: reassorted viruses comprising genes for surface antigens of equine influenza viruses and the RNA7 segment from A/PR/8/34; methods of obtaining such viruses by reassortment; methods of propagating such reassorted viruses in cell culture, especially Vero cells; vaccines against equine influenza comprising such reassorted viruses; and methods of vaccinating equines against influenza.

With the transfer mechanism being in its upper position, the guides are respectively located between the rest position of said gathering head and the paths of yarn travel, respectively, such that when the cutter means severs the yarns and the gathering head returns to its rest position the yarns engage respective ones of the guides.  The guides are moved from the upper position to the lower position relative to the gathering head and with the yarns remaining engaged with the guides, so that the yarns can be threaded onto empty packages.  The gathering head is also usable on a hand-manipulable aspirator.

Abstract: ABSTRACT OF THE INVENTION      PULSED APERTURE FOR AN ELECTROSTATIC INK JET SYSTEM           Disclosed is an electrostatic ink jet printing system which provides improved frequency response of the mass flow of ink deposited on a recording medium.  In accordance with the invention, an ink jet nozzle is conductively connected to an ink reservoir.  A conductive platen maintained at a reference voltage level is positioned in front of the nozzle.  A sheet of paper is positioned on the surface of the platen. Positioned between the paper and nozzle is a conductive plate having an aperture through which ink emanating from the nozzle is directed.         A video data signal input to the system is amplified and biased before being applied to the nozzle.  At the same time, the video data signal is also inverted, then fed through a differentiator and finally amplified before being applied to the conductive plate.          As a result of the voltage signals applied to the nozzle and plate, a unique electric field is generated between the tip of the nozzle and the plate.  This electric field exerts a force on the ink at the tip of the nozzle causing a mass flow of the ink.  As a result of the unique characteristics of the electric field, the frequency response of the mass flow is improved,  thereby producing sharper images on the paper.
