Abstract: HOT MELT ADHESIVE SYSTEM         Abstract of the Disclosure A hot melt foam adhesive system including a gear pump wherein gas is mixed under pressure into the molten adhesive and is driven into solution with the adhesive.  The adhesive/gas solution is supplied at a relatively high pressure to a valved dispenser or gun from whence it is dispensed onto a substrate.         As the adhesive/gas solution emerges from the dispenser, the gas comes out of solution but remains entrapped in the adhesive, thereby forming an adhesive foam.  The system includes a recycle flow line or hose for returning adhesive/gas solution from the dispenser to the pump.  Within this recycle flow line there is a pressure regulator responsive to flow changes or viscosity changes of the adhesive/gas solution for maintaining a fixed back pressure in the system, thereby enabling the system to maintain a fixed and uniform flow rate from the dispenser during all operating conditions of the dispenser.

Abstract: FRAME SYNCHRONIZATION WITH SLIP COMPENSATION            Abstract of the Disclosure Frame synchronization to the framing pattern of a DS3 bit stream is achieved by detecting the framing pattern and producing a synchronizing slip in the absence of such detection.  In order to avoid long framing times as a result of unconfigured adjacent DS1 transmission links producing data which mimic the DS3 framing pattern, redundantly transmitted stuff information (tributary justification control) bits are also checked to ensure that appropriate bits, relative to the position of the framing pattern bits, have expected properties (e.g. triplicated values), and a synchronizing slip is also produced if this is not the case.  Short framing times are also achieved by storing in each of the framing pattern and stuff information bit detectors not only the particular bits which are currently to be checked, but also consecutive bits which are selected in dependence upon the occurrence of previous synchronizing slips.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE    A valve stem packing assembly comprises a stacked assembly of V-ring seal elements, special back-up energizing rings interspersed between the seal elements and a spring-energized lip seal ring that is retained in the functional position by an adapter ring having a generally T-shaped cross-sectional configuration.  As the assembly is installed in a valve stem packing chamber with the T-adapter ring at one end of the assembly and a back-up ring for the V-ring seal elements at the other end, the lip seal ring and the V-ring seal elements are radially compressed to establish an initial seal between the stem and the chamber wall.  When the assembly is subjected to interval valve pressure the V-ring seal elements and the lip seal ring are additionally compressed and deformed to fill annular spaces that may still exist between the seal elements, their back-up/energizing rings and the lip seal ring, thereby establishing an essentially void-free dynamic packing between the stem and the chamber wall that is capable of withstanding many hundreds of gate valve stroke cycles (valve open to closed to open constituting one cycle) at unusually high pressures of fifteen thousand pounds per square inch and above, and unusually high temperatures of two-hundred and fifty degrees Farenheit and above.  Furthermore, a stem packing assembly according to the present invention is extrusion-free, insensitive to fluctuations in pressure and/or temperature, and exceedingly resistant to chemical attack.

Abstract: ABSTRACT OF DISCLOSURE   A gravity blending apparatus and methods of gravity blending involving an improved venting arrangement, by means of which an increase in the "thru-put" flow rate of a gravity blender apparatus is provided by venting the underside of an inverted cone within a collecting chamber to one or more low pressure zones. Advantageously, such venting may proceed progressively from the underside of an inverted cone within the collecting chamber to a low pressure zone within the upper portion of the collecting chamber, with venting continuing by way of auxiliary or further venting conduit means to the underside of a material distributing, inverted cone in the lower portion of the base of the main bin of the gravity blender. A gap between the terminus of a central, lower most outlet of the main bin and the apex of the inverted cone within the collecting chamber may be selectively ajusted so as to regulate the relative flow rates of the central, lower-most outlet of the main bin and the peripheral down-comers contained within the main bin which are located circumferentially outwardly of the central outlet and draw material from above the main outlet within the main bin. Such adjusting is able to be effected externally of the main bin and collecting chamber so as to avoid the necessity to obtain access to the interior of these components.

Abstract: FLOW CONTROL SCHEME FOR A SWITCHING NETWORK          Abstract A flow control mechanism for a packet switching system that provides for the continuous dynamic control of station window size beginning with call setup and extending through the duration of the call.  A station window size can be of a first magnitude at call setup time when system traffic may be low.  The window size can be subsequently reduced to free up port buffer space as system traffic increases.  This permits the serving of more calls during periods of heavy traffic.

Abstract: EXPANDABLE URETHRAL BOUGIES            ABSTRACT: A mechanically-expandable instrument (bougie), especially useful for treating diseases in the urethra and the neck of the urinary bladder, comprises an adjustable-speed driving unit (20) and a probe (22) composed of two rods (64) and (66) pivotally connected together at one end thereof and attached to output sliders (54, 56) of the driving unit at their other ends. Each of the rods (64) and (66) has a semicircular cross section so that in an assembled state the probe has a complete circular cross section. Reciprocations of the sliders cause expansions and contractions of the probe, thereby to stretch urethral constrictions in the radial direction and to subject the urethra and its surrounding tissue to messaging and vibrational actions which are extremely efficient for treating diseases of the urethra and the neck of the urinary bladder. Other embodiments of the rod employ cams, wedges, and threaded means for creating radial expansions and contractions of the probe.

Abstract: Sensing occurs between the drafting mechanism and the flyer head, and a fault signal is generated if the sliver breaks, or information of a pile of fibres is sensed over the head, a feeler which does the sensing being pivoted to either side of a normal sliver-engaging position. Specifically the feeler, has a portion engaging the sliver, and a second portion above the flyer head for fibre-pile sensing. Signalling lugs on the feeler more into a light beam, directed towards a p.e. cell, if a sliver fault is sensed, or alternatively a magnet on the feeler operates a dry reed switch. The lever is counterweighted, as by the magnet.
