Abstract: Abstract of the Disclosure A circuit for limiting impulse noise contained in a signal is disclosed.  The circuit comprises a delay circuit connected in parallel with a clamp circuit which is formed of two oppositely directed parallel diodes.  When a signal is applied to an input of the parallel connected delay and clamp circuits, the clamp circuit prevents the voltage of the input signal from rising higher than a value (positive or negative) which will cause one of the diodes to conduct.  Thus, impulse noise can be re-moved from the input to the delay circuit which provides an output signal essentially noise free and delayed with respect to the original signal.

Abstract: Abstract of the Disclosure A snap fastener is disclosed which is resistant to accidental opening but can be easily opened by an appropriate application of pressure.  It has male and female parts and is characterized in that the female part comprises two ring like elements placed above and below a flexible lamina on which they are to be fixed.  One of these elements has pin-like lugs and the other element has a cylindrical cavity which terminates in a conical part.  When the parts have been aligned and are pressed toward one another, the lugs penetrate the flexible lamina and are guided by the cylindrical part of the opposed element and are folded outwardly by the conical part and are finally directed into a cavity provided for this purpose, whereby the two ring-like elements are coupled together on opposite sides of the flexible lamina without any need for the cutting of a hole in the lamina.  The upper element of the female part is formed by two pieces which are united and contain between them a movable locking piece which functions as a push-button to facilitate the opening of the fastener while at the same time constituting a decorative element of the combination.

Abstract: ABSTRACT      A jointing device including arms which connect two elements together.  The arms are elongated and of generally rectangular cross-section.  One of the elements includes flanges with lips extending along the edges of the flanges and the other of the elements forms a clip.  The lips form a mouth.  Each arm is grooved near one end, the grooves extending transversely across one of the elongated faces of the respective arm.  Said one end of each arm is bounded by a rolling surface which intersects said one surface of each arm and merges with the opposed surface.  With the rolling surface in engagement, the arms diverge from said one end and, in this condition, can be inserted into, and removed from, said mouth.  When the outer ends of the arms are moved together from this diverging position, the arms are brought into back-to-back relationship with the opposed surfaces juxtaposed.  The lips are received in the grooves while the arms are held in back-to-back relationship in the mouth. The arms are held in this relationship by the second element which straddles the arms.  The lips are forced apart as the arms are brought into this relationship because the distance between the bottom of the grooves in greater than the initial distance between the lips. The advantage of this invention is to provide joints and cantilever bracket supports which are easily assembled and disassembled.  It will be understood that joints between may be made between a variety of shapes with  lipped channel openings, but also between one element incorporating a lipped channel and another element in a variety of other forms, such as round or square tube and the like and other devices providing a means of holding the two arms of the locking device in the locked position.  The locking arms may be extruded or cast, the shape which protrudes may vary depending on its function.

Abstract: ABSTRACT         De-watering of an aqueous slurry of polymer beads which contains a poly(vinyl alcohol) dispersion stabiliser by a physical separation such as filtration, can be seriously impeded by blinding of the filter bed, reducing throughput rates to an intolerably low level.   A process is disclosed in which efficient dewatering by physical means such as filtration can be achieved.       An insoluble organic destabiliser is formed in situ in the slurry from a soluble parent compound comprising solubilising ionisable groups.  The slurry may then be filtered at a temperature not lower than 50°C to yield a soft cake of polymer beads, essentially free of poly(vinyl) alcohol) dispersion stabiliser.

Title: Enhanced cross-flow with two jet drilling

Filed: 1979-06-19
Granted: 1981-02-10
Abstract: ABSTRACT           This invention relates to hydraulic circulation systems for cleaning holes being drilled in rock and earth with drilling bits. One of the limiting parameters in three-cutter drill bits in the past is the lack of space for fluid flow passage from the hole bottom to the top of the bit.  The present invention overcomes this deficiency of the prior art by providing a drill bit having three cone-shaped cutters and formed with two drilling fluid nozzles on opposite sides of one of the cutters and with an enlarged return passage for the drilling fluid formed between the other two cutters.  Flow restrictors adjacent the two nozzles restrict the flow of return fluid in those areas.  A flow diverter in the dome area of the bit extends into the space between the cutters to better direct fluid across the bottom of the hole where cuttings are being generated by the cutter teeth.

Abstract: Abstract of the Disclosure An improved elongate deformable tube for use in the conveyance of fluids and/or fluid transmission signals under pressure having a bore therethrough enclosed by a composite annular wall comprising a seamless, as welded, or welded and drawn inner tubular shaped layer made from a metallic material and an outer tubular shaped layer made from a polymeric mater-ial.  The walls of both the inner and outer layers are substan-tially uniform in radial thickness around their circumference with the radial wall thickness of the outer polymeric layer being 50% or more than the total radial thickness of the compo-site wall of the tube.  The outer layer is preferably formed about the inner layer by means of an extrusion process.  The inner and outer layers are bonded together by means of a poly-amide based hot melt adhesive interposed therebetween which preferably contains an amount by weight of piperazine used in the process of making the polyamide which is less than about 15% by weight to the total weight of the polyamide and that is sufficient to enhance the bond between the layers without ad-versely affecting its resistance to water degradation.  The outer diameter of the outer layer is sized, during the process of making the tube, such that the tube can be attached, without further dimensional alteration, to fittings standardly used to couple equivalently dimensioned tubes having a singular poly-meric or metallic wall.
