Abstract: ABSTRACT OF THE DISCLOSURE      To prevent tampering with the contents of containers for pharmaceuticals and other products, a plastic cap which is an improvement upon U. S. Pat. 3,338,446 and 4,166,552.  The neck of the container is sealed with a commercially available foil seal; the cap is dimensioned to that the foil seal is inserted inside the cap prior to its being applied to the container.  The dimensions of the cap accommodate the foil seal yet the snap-on and the tamper-proof features of the cap are maintained.  At intervals, scorelines are formed extending upward from the bottom of the cap skirt; these tear if one attempts to pry the cap off the container and are visible evidence of the tampering.  A flexible, thin flange projecting from the periphery of the cap is used to remove the cap in its reclosure mode; however, this flange has a sharp corner where it meets the cap skirt so that if one attempts to use the flange to pry off the cap when in its original sealing mode, the flange tears and gives additional evidence of tampering.

Abstract: Abstract of the Disclosure A product pump assembly including a product pump having a product receiving inlet, a product discharge outlet, a product chamber, and an air port.  A cone-shaped feed valve in the product chamber is forced upwards against the inlet thereby sealing it when pressurized air is forced through the port into the chamber, during the evacuation cycle of the pump assembly.  The pressurized air is deflected against the valve sweeping the product out of the chamber through the outlet and via a delivery line to the product collector.  An ejector is energized during the fill cycle to withdraw the air from the chamber through the air port, thereby opening the valve and pulling the product into the chamber.

Abstract: OXYGEN REACTOR DEAERATION TANK AND SYSTEM                   ABSTRACT OF THE DISCLOSURE          A small deaeration tank which may be either at atmospheric pressure on under low pressure or vacuum and a system of operating this tank which allows pulp which has been treated with oxygen to be deaerated before being washed. A closed tank would allow steam or oxygen to be recovered. Preferably it would be the same diameter as an oxygen reactor so that it could be placed on top of the reactor and be supported by the reactor. It would have no moving parts, so there would be no need for motors to be mounted on or near the tank. The deaerator is a small open tank having an inlet pipe, an outlet pipe, and a tangential swirl inducing inlet pipe. The locations and sizes of these pipes provide optimum deaeration. The swirl inducing fluid is the filtrate from the washer after the oxygen bleach.

Abstract: ABSTRACT OF THE DISCLOSURE   A universal joint for transmitting driving torque between rotative embers including an inner joint member for connection to one of the rota-tive members and an outer joint member for connection to the inner joint member and to the other of said rotative members. The inner joint member swivels within the outer joint member by virtue of contacting inner and outer spherical surface portions on the outer and inner joint members, respectively. Torque is transmitted between the inner and outer joint mem-bers by a plurality of roller balls which extend between a recess in the inner joint member and a plurality of circumferentially spaced-apart  rec-tilinear recesses in the outer joint member which are disposed between the spherical inner surface portions on the outer joint member. The recess in the inner joint member permits the spherical roller balls to come into con-tact with one another, and the rectilinear recesses in the outer joint member permit the roller balls to separate when the inner and outer joint members articulate with respect to one another.

Abstract: Abstract of the Disclosure A process is disclosed for routing service requests through a network comprising nodes interconnected with links.  The network is also arranged so that each node may communicate with each of the other nodes.  At preselected time intervals, sets of routes through the network are generated in response to the network configuration and traffic information.  Also, at predetermined time intervals, occupancy factors are computed as determined by the network configuration and in response to traffic information.  Upon a request for service, the occupancy factors corresponding to the busy-idle status of the links are used to compute an occupancy value associated with each of the routes.  Each route is converted to a candidate route based on traffic load at the initiation of the service request.  The minimum occupancy value for each set of routes is selected as the candidate route for bridging a given node pair.  If this minimum value is less than a preselected threshold, the traffic is routed over this candidate route, thereby satisfying the service request. Otherwise, the request is denied.
