Abstract: ABSTRACT OF THE DISCLOSURE            Drag reducing means adapted to be mounted on the roof of the cab portion of a land vehicle in-cluding a trailing body for reducing aerodynamic drag.          The drag reducing means comprises a streamlined fair-ing including a bottom portion, a rear portion, a nose portion and a continuous contoured surface ex-tending widthwise and upwards from the nose portion to the rear portion.  The contoured surface has a top portion and side portions which abut at their respec-tive boundaries.  The top portion has a segment the tangential plane of which is inclined with respect to the horizontal at an angle which is less than or equal to approximately tan-1[2(H-h)/x] and greater than or equal to zero, where H represents the verti-cal distance from the roof of said cab portion to a top wall of said trailing body, h represents the height of said fairing, x represents the distance be-tween the rear portion of said fairing and the front of said trailing body, and h has a value greater than or equal to about .9H and less than H.  The fairing is also designed so the segment of the top portion is located furthest from the bottom portion.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE           POSITION OF PRINTED INK DROPLETS                      Abstract Each ink droplet printed on a recording surface, which has relative movement along a first axis with respect to ink droplet producing means, forms part of a character, and may be disposed in any granular position in a second direction, which is substantially orthogonal to the first axis, relative to a single predetermined position, which is the gutter stream position.  Information concerning the location on the recording surface of each printed droplet relative to the single predetermined position in the second direction and to the prior printed droplet or a margin along the first axis is stored in a read only storage (ROS).  The information concerning the location of the droplet in the second direction is a voltage applied to charging means with the magnitude of the voltage in conjunction with any induction created by prior adjacent droplets of the ink stream determining the deflection of the droplet.  Synchronization of the relative movement along the first axis with respect to the generation of the droplets is obtained whenever there is a predetermined spacing between the printed droplets along the first axis after it has been determined that synchronization is required.

Abstract: Favin-20 75.          MULTITONE FREQUENCY RESPONSE AND ENVELOPE DELAY DISTORTION TESTS            Abstract of the Disclosure Accurate and reliable measurement results are obtained in a test system (FIG. 1) employing digital data acquisition units when measuring frequency response or envelope delay distortion of a network or communication facility by employing a unique test signal (21-tone) including a plurality of tones, each tone having amplitude, frequency phase component values determined and assigned in accordance with prescribed criteria. The phase component values are determined in accordance with a relationship dependent on the  number of tones in the test signal, and in one example, are initially assigned on a random, one-to-one basis to the tones.  In a specific embodiment, a test signal is utilized having 21 tones.  Further problems arising from nonlinearities on the facility under evaluation are minimized by transmitting the 21-tone test signal a plurality of times and by reassigning the phase component values to the tones each time the test signal is transmitted.   In a specific example, the phase component values are re-assigned to the tones in counterclockwise, circular fashion after each transmission of the test signal until each tone has taken on each phase component value. Once measurements, i.e., data records, of the transmitted test signal have been obtained, they are utilized to obtain a spectrum, and in turn, the frequency components of the spectrum are employed to obtain the desired measurement of frequency response or envelope delay distortion.

Abstract: Abstract of the Disclosure A non-woven fabric is manufactured which utilizes as a primary component material the fringed selvage band resulting as a by-product in the manufacture of certain woven fabrics.  Strips of selvage band are laid down on a non-woven backing or web in various configurations, depending upon the ultimate appearance that is desired.          The selvage strips are then secured to the backing by punching with an array of forked needles, each of which forces a loop of yarn from the selvage through a hole in the backing.  Prior to this invention, selvage has been considered an unattractive by-product of no practical value and has not previously been used in creating an attractive fabric.

Abstract: GRAB MECHANISM ABSTRACT OF THE DISCLOSURE    A grab mechanism device for transporting a plurality of vertically oriented plates having lift lugs from a holding container such as a vat.  The grab mechanism is mounted on a vertically movable load frame.  The grab mechanism and load frame overlie the vat.  An aligner frame is slidably mounted relative to the load frame and has mechanical guides for positively aligning said aligner frame with the holding container in position overlying the plates.  The load frame can be lowered relative to the aligner frame forming part of the grab mechanism in position to engage the lift lugs of the plates.  The grab means is selectively controlled to engage a set of the plates in the container or vat.  The plates are lifted out of the container by lifting the load frame and grab mechanism relative to the aligner frame.  The aligner frame may include "combs" for interdigitally separating the bottom of the plates from one another after the plates have been lifted from the holding container.  Then the load frame grab mechanism plates and aligner frame may be lifted clear of the container and moved by a crane, for example, to a remote location.

Supported by the housing between the inlet and outlet orifices is a flexible diaphragm with wall portions that open a flow path between the orifices when in an open position and close the flow path when in a closed position. The diaphragm has first surface portions exposed to the primary chamber and surface portions opposite the first portions and expand to the pilot chamber. In response to a predetermined difference in pressure between the pilot and primary chambers, the wall portions are moved to the open position and are retained in closed positions by less than the predetermined difference in pressure. A pilot valve controls fluid flow through the release port and in response to a fire condition, a sensor moves the normally closed pilot valve into an open position and whereby produces a differential pressure across the wall portion that opens the diaphragm main valve.
