Abstract: Abstract of the Disclosure A reaction chamber having an evacuated volume defined by a central plane and a central axis perpendi-cular thereto is associated with a magnetic field genera-tor providing a field decreasing in strength with in-creasing radial distance from the central axis and in-creasing in strength with increasing distance from the central plane along the central axis and further with an accelerator which injects a molecular ion beam from the periphery of the volume into the vicinity of the center of the volume substantially coplanar with the central plane.  The ion beam is conditioned prior to its in-jection into the volume to contain a population distri-bution of molecules in higher vibrational states than in the case of a normal population distribution whereby collisionless dissociation of the injected molecules is enhanced centrally in the volume due to the magnetic field configuration.

Abstract: ABSTRACT         A hydraulic motor includes an elongated output member which is supported for rotational movement about a central axis thereof.  The output member is driven by a gerotor gearset which includes an outer member having internal teeth which mesh with external teeth on an inner member.  The inner member is fixed against movement and the teeth on the inner member and outer member define a series of expansible and contractable fluid pockets. The outer member orbits and rotates as a result of fluid being directed into certain of the fluid pockets to expand same and fluid is directed from con-tracting pockets.  A tubular member drivingly connects the outer member and output member and transmits driving torque to the output member.  The tubular member is connected in a 1:1 rotational driving relationship with the outer member and output member.  The driving connection of the tubular member to the outer member and output member is such that the tubular member can rock relative to these members so that its motion describes a cone as it follows the orbital motion of the outer member and transmits rotary motion to the output member.

Title: Apparatus for producing thermoplastic tubing
Inventor: LUPKE GERD P H
IPC: B29C48/13
Filed: 1977-02-07
Granted: 1980-08-19
Abstract: In apparatus for producing multi-walled thermoplastic tubing having a corrugated wall and a substantially smooth inner wall secured to the corrugated wall, there is incorporated two sets of endless flexible belts each of which is entrained around rotatable end rolls, the outer runs of the belts of one of the sets thereof alternating with the outer runs of the other of the sets thereof, with these outer runs of the various belts serving   to urge the inner wall against the corrugations of the corrugated wall while the thermoplastic material of the walls is soft thereby to secure the walls together, and with an electrically energizeable heating coil being provided for softening the thermoplastic material of the corrugated wall to ensure satisfactory securement between the walls.  The apparatus also incorporates a suction chamber, a cooling chamber forwardly of the suction chamber, and a pressure chamber forwardly of the cooling chamber, the suction chamber communicating with passages in the mold blocks which constitute a tubular mold tunnel in which the tubing is formed to urge the appropriate wall against the tubular mold tunnel thereby to form the corrugated wall, cooling air flowing from the cooling chamber through these passages and exhausting through spring-loaded check valves to cool the mold blocks, and pressurized air flowing from the pressure chamber through the passages to eject the finished tubing from the tubular mold tunnel at the forward end thereof, during which the check valves are maintained closed.  Particles of a tracer material may be deposited between the corrugated wall and the inner wall in order to facilitate detection of the tubing when the tubing is subsequently in use as underground tubing, and a foamable material may be deposited in the corrugations on the inner face of the corrugated wall, this foamable material subsequently foaming to occupy these corrugations and thereby increase the strength of the tubing after the inner wall has been secured to the corrugations of the corrugated wall.

The frozen mass is then thawed, washed, and immersed in a wash of pH 8 to 9 fox approximately 2 hours at 20° centigrade.  Sufficient reducing agent is added to the  wash to create excess reducing equivalents,  The sponge is then immersed in a buffer solution of pH 4 to 5 for a time sufficient to equilibrate to uniform pH.  The sponge formed by the above method is then moistened and self-administered in the upper vault of the vagina proximal to the cervix.  The sponge is then retained for a desired period, usually several days to one month.
