Abstract: ABSTRACT OF THE DISCLOSURE           A double lumen cannula for hemodialysis and similar applications such as haemoperfusion comprises elongated flexible tubular members, disposed one within the other, for semi-permanent insertion into the sub-clavian vein of a patient, leaving semi-permanent access thereto for repeated hemodialysis treatments.          The cannula is formed of an elongated flexible outer member, having a smooth exterior surface, and made up of an elongated main portion, a convergent, constricting portion and a narrower distal end portion which is tapered at the tip to fit over a Seldinger guide wire.  There is also an inner member having a diameter substantially the same as that of the distal end portion.          The inner member is insertable into the outer member to come into sealable engagement with the interior walls of the constricting portion, so as to form a continuous inner lumen with the distal end portion of the outer member, and is removable therefrom for removal of clot or replacement purposes.  Both members are sufficiently flexible to permit curving thereof on a 12 cm radius without reduction in internal cross section thereof, i.e. without substantial kinking or buckling, so as to avoid constriction of fluid flows. Because the cannula provides two pathways for simultaneous extraction and return of blood there is no need to use a single needle machine to produce an alternating blood flow.

Abstract: IMPROVED TOUCH PAD AND DISPLAY TUBE CIRCUITRY            ABSTRACT OF THE DISCLOSURE      Improved touch pad and display tube circuitry including a touch pad circuit, a tube circuit, and a scan voltage pulse drive circuit for generating scan voltage pulses applied to the touch pad and display tube circuits. The touch pad circuit receives scanning voltage pulses having very fast rise-times, to reduce the effects of contaminants which may be present on the surface of the touch pad panel. The display tubes of the display tube circuit each include an anode, a plurality of display cathodes and a control cathode.          The current flowing through the control cathode is proportional to the current in the associated display cathodes.The control cathode current is utilized by the drive circuit to adjust to a desired value the value of the magnitude of the scan voltage pulses applied to the anodes of the display tubes. The drive circuit utilizes a substantial portion of common circuitry to generate both the touch pad and display tube scan voltage pulses. The control circuit also functions to isolate the touch pads and display tube anodes in such manner that the fast rise-time pulses applied to the touch pads are not coupled to the display tube anodes.

These partial outputs are fed to loww pass filters.  Each filter has a cut-off frequency component cor-responding to each of the output frequencies to remove there-from clock components.  Outputs of the low-pass filters are added together to obtain a synthesized waveform.

Abstract: ABSTRACT OF THE DISCLOSURE    .         A method for effectively encasing an active agent such as a chemical compound, a seasoning, a flavoring, or a nutrient such as vitamins and minerals, including liquids, as a time-stable but releasable dispersion in a homogeneous polymeric encapsulating matrix of a modified starch, a gum or a protein material such as gelatin and casein to provide a concentrate of the active agent.  The method is characterized in that the agent,toibe encased is mixed with the encapsulating material under conditions of rigorous and intimate mechanical working with applied high shearing stress but without phase-separating mechanical compression and compaction forces and in the presence Of a limited quantity of Water and suffi-cient heat to ensure the formation of a viscous, semisolid, homogeneous paste constituting a mobile mass or plastic melt. The melt, consisting of a homogeneous matrix with the encased agent distributed therethrough as a microdispersed phase, is then formed into any desired shape, while avoiding phase-separating compaction and compression forces, and dried to provide a product stable against loss and deterioration of the encased agent.  In a preferred embodiment of the invention the encased agent is gradually released from the matrix at a rate dependent on the rate of hydration of the matrix.

Abstract: Abstract:   The invention relates to a multi-ply vessel which comprises an inner layer composed of a thermoplastic polyester resin, a middle layer composed of a metaxyly-lene group-containing polyamide resin and an outer layer composed of a moisture impermeable synthetic resin.  The inner layer and middle layer are orientated in at least one direction at the thin parts of the vessel wall.  This vessel can be produced by orientating a parison having the above-mentioned multi-ply structure at a draw ratio of 1 to 4 times in the longitudinal direction and of 2 to 7 times in the crosswise direction at a temperature of from Tg + 15°C to 2(Tg) + 15°C (wherein Tg is a glass transi-tion temperature of the thermoplastic polyester resin).

Abstract: ABSTRACT    A flameless nitrogen vaporizing unit includes a first internal combustion engine driving a nitrogen pump through a transmission.  A second internal combustion engine drives three hydraulic oil pumps against a variable back pressure so that a variable load may be imposed upon the second engine.  Liquid nitrogen is pumped from the nitrogen pump driven by the first engine into a first heat exchanger where heat is transferred from exhaust gases from the first and second internal combustion engines to the liquid nitrogen to cause the nitrogen to be trans-formed into a gaseous state.  The gaseous nitrogen then flows into a second heat exchanger where it is superheated by an engine coolant fluid to heat the gaseous nitrogen to essentially an ambient temperature.  The superheated nitrogen is then injected into the well.  The engine coolant fluid flows in a coolant circulation system.  Heat is transferred to the coolant fluid directly from the internal combustion engine. Heat is also provided to the coolant fluid from lubrication oil pumped by the three pumps attached to the second internal combustion engine.  The coolant fluid circula-ting system includes a comingling chamber for comingling warmer coolant fluid flowing from the internal combustion engines to the second heat exchanger with cooler coolant fluids flowing from the second heat exchanger to the internal combustion engines.  Methods of vaporizing nitrogen are also disclosed.
