Abstract: Abstract of the Disclosure A miniature implantable magnetically actuated valve relatively insensitive to normally-encountered shock loads includes a housing for containing a movable ferromagnetic valve member.  Inlet and outlet passages are provided in the housing at least one of which has an internal valve seat which is engageable by the valve member to close that passage.  The valve member is resiliently suspended within the housing by special flat multiply-started spiral springs which permit the valve member only a single degree of freedom toward and away from the valve seat.  The valve member is biased in one direction or the other and the valve is actuated transcutaneously by a magnet juxtaposed to the valve outside the body which produces a magnetic force on the valve member which exceeds and opposes the biasing force.

Abstract: ABSTRACT      A process is described which uses a modified double distillation cycle for rejecting nitrogen from a natural gas stream containing varying amounts of nitrogen, methane, carbon dioxide and ethane-plus hydrocarbons. The natural gas stream is fractionally distilled in the high pressure distillation stage of the double distilla-tion cycle to provide a nitrogen overhead and a bottoms comprising carbon dioxide and ethane-plus hydrocarbons. A sidestream consisting essentially of nitrogen and methane is withdrawn from the high pressure distillation stage as intermediate level feed to the low pressure distillation stage of the double distillation cycle. The nitrogen overhead from the high pressure stage is cooled by heat exchange with the methane bottoms of the low pressure stage which methane bottoms acquires an extra degree of refrigeration from a methane heat pump cycle to provide extra nitrogen reflux to thoroughly remove the carbon dioxide from the natural gas stream in the high pressure stage.

Abstract: METHOD AND APPARATUS FOR WASTEGATING               TURBOCHARGED ENGINE WITH DIVIDED                       EXHAUST SYSTEM          ABSTRACT           A turbocharged engine is provided with a turbine housing which has an inlet, an outlet located radially interiorally from the inlet, a centrally located turbine wheel cavity, and an internal scroll passageway which diminishes in cross section as it leads from the inlet around the turbine wheel cavity.  The scroll passageway means is bifurcated from the inlet through an arc of between 180° and 300° to divide the incoming exhaust gas from different sets of cylinders of an internal combustion engine into identical, but separate, flow paths to minimize feedback of pulsations of exhaust gases from one set of cylinders to the other.  The separate, flow paths within the turbine housing are combined into a single flow pathway near the end of the scroll passageway, and a single wastegate valve is in communication with the single flow pathway.  A portion of the exhaust gases is selectively diverted from the single flow pathway to the single wastegate valve to maintain maximum speed of operation of the turbine wheel.

Abstract: COLLISION AVOIDING SYSTEM AND PROTOCOL FOR A TWO PATH MULTIPLE ACCESS DIGITAL          COMMUNICATIONS SYSTEM   Abstract In order to control the transfer of packets of information among a plurality of stations, e.g., digital computers, the instant communications system and protocol contemplate first and second oppositely directed signal paths.  At least two stations are coupled to both the first and the second signal paths.  A station includes arrangements for reading one signal from the first path and for writing another signal on the first path.  The one signal is read from the first path by an arrangement which electrically precedes the arrangement for writing the other signal on the first path.  A similar read arrangement is electrically preceding a write arrangement on the second path.  If the station has a packet to transmit, it can overwrite a busy control field of the one signal packet on either path.  Having read the one signal on the path, a logical interpretation may be made within the station as to whether the path is busy or is not busy.  If the path is not busy, the packet may be written on the path by overwriting any signal thereon.  If the path is busy, the station may defer the writing until the path is detected as not busy through a busy control field.  The packets flow down the path to a destination station.  Eventually all packets will be transmitted and the busy control field may be detected at an end station for indicating the event that all packets have been transmitted.  The end station on one path acts as the head station on the other oppositely directed path.  Hence, responsive to detecting that all packets have been transmitted, the head station on the other path may transmit an end cycle packet, responsive to which event a new cycle may be started by initializing each station on the one path and by permitting each initialized station to transmit.

Abstract: ABSTRACT          Steam-cooling with a steam thermal barrier for vanes and blades in a gas generator  or power turbine is disclosed.  This has particular application to apparatus for generating useful power by reheating gas generator turbine exhaust gases to directly generate power, or alternatively, by reheating this exhaust gas to directly generate power and further reheating superheated steam by heat exchange for combined gas reheat and steam superheating with optional steam reheating as well.          Steam-cooling offers advantages over cooling with air or water at the higher temperatures characteristic of the high temperature turbine technology gas turbines coupled with the reheat steam cycle.  Consequently, higher cycle efficiency is obtainable for turbine initial firing temperatures of about 2500°F (1371°C) and 2050°F          (1121°C) reheat temperatures where over-all combined cycle degradation resulting from steam cooling is below about 1%.  A turbine having steam-cooled components can operate at a cycle pressure ratio of about 38 without intercooling and can include steam superheating in the reheat combustor.  To accomplish steam cooling, steam is introduced into an internal steam distribution plenum in the turbine blading and is then directed, through nozzles, to the external surface of the blading.

Abstract: A BLOOD COMPONENT STORAGE CONTAINER AND METHOD UTILIZING A POLYVINYL CHLORIDE PLASTIC FORMULATION           FREE OR ESSENTIALLY FREE OF    LEACHABLE MATERIALS                      ABSTRACT A blood component storage container(l0)is made of a plasticized polyvinyl chloride formulation which includes a heat stabilizer system selected from the group consisting of salts of C10 to C26 saturated fatty acids present in an amount of less than about one percent by weight of the composition.  Surprisingly, use of only minimal amounts of these higher molecular weight fatty acids results in an effectively heat stabilized product suited for mass production techniques.  As a result, the total amount of the heat stabilizer which can possible leach into blood plasma is significantly reduced.  The material from which the container (10)is made preferably includes an effective amount of a plasticizer which is also essentially nonextractable in blood plasma.

Abstract: MOLD MASKING APPARATUS AND METHOD          Abstract of the Disclosure A method and apparatus is disclosed for powder coating the interior surface of a heated mold cavity. Electrostatically charged powder is sprayed upwardly onto the interior surface of a mold surrounded by a mask.  The mask includes a shield located adjacent to but spaced from the shear edge of the mold.  Addition-ally, the mask includes a vacuum duct located beneath the shield.         While air is drawn into the vacuum duct air is either blown through the slot defined between the shield and the mold shear edge or air is pulled into the slot so as to prevent oversprayed powder from coming into contact with and adhering to the shear edge of the mold.  There is no enclosure surrounding the mold cavity other than the mask because rising heated air currents entrap and maintain the cloud of sprayed powder interiorly of the mold cavity and the surrounding mask.  Any oversprayed material escaping from the cavity is caught in the vacuum duct and carried to a powder collector.
