Abstract: ABSTRACT OF THE DISCLOSURE The overflow in the secondary of a steam genera-tor of a nuclear-reactor plant, which occurs when one or more primary tubes conducting the coolant are ruptured, is controlled.  The secondary of the steam generator,  which contains the water that is converted to steam, is connected through valves to the pressurizer relief tank.  The level of  the  liquid  in the  shell  is monitored.  An alarm is sounded when the  level  of  the  liquid  in the  generator reaches a predetermined height alerting the operator.  When the level reaches a greater height, the valves are opened and the liquid in the shell is discharged into the pressur-izer relief tank.  The liquid in the tank is discharged into the containment sump when a disc is ruptured.  The time taken after the rupture is 30 minutes as mandated by safety  regulations.   If,  after  the  liquid in the  shell reaches the level at which the valves are opened, the level drops to a height at which steam may be injected into the pressurizer  relief  tank,  the  valves  are  automatically closed.  The valves include a normally-open valve and a normally-closed valve connected in series in each of two parallel branches.  A normally-open valve in one branch and a normally-closed valve in the other branch is connected to be actuated by one power train and a normally-open valve in the other branch and a normally-closed valve in the one branch  are  connected to be  actuated by  a  second power train.  Single failure protection is thus provided.

Abstract: BATTERY CHARGING SYSTEM INCLUDING MEANS FOR DISTINGUISHING BETWEEN RECHARGEABLE AND NON-RECHARGEABLE BATTERIES                 ABSTRACT OF THE DISCLOSURE           A battery charging system is provided which distinguishes between primary and secondary batteries by sensing a charging or discharging parameter of a battery placed into the system.  A sensing means is included in the system which senses the value of at least One parameter of the battery.  The parameter has a value for secondary batteries which is distinctive from its value for primary batteries.  In response to an indication from the sensing means that the battery in the system is a primary battery, an enabling means disables charging of the primary battery by the system.  The enabling means, in response to an indication from the sensing means that the battery in the system is a secondary battery, enables charging of the secondary battery by the system.  One battery parameter which is particularly useful in discriminating between primary and secondary batteries is the low frequency impedance of the battery during charging.

Abstract: TITLE STABLE NITRATE/SLURRY EXPLOSIVES    ABSTRACT OF THE DISCLOSURE       Explosives that are sensitized blends of inorganic nitrate. e.g., AN, particles, such as AN or ANFO prills, and an aqueous slurry comprising a thickened aqueous solution of an inorganic oxidizing salt, preferably AN, are rendered storage-stable by keeping the slurry's water content low enough, and its viscosity high enough, that the slurry is water-retentive.  Water immobilization in the slurry, a requirement for storage stability, is achieved despite the slurry's flowable consistency at the time of blending. A blend containing about 25% slurry or less is essentially in the form of a granular mass of free-flowing, high-density, slurry-bearing prills, and the slurry is sensitizable by the prills alone.  As the slurry content exceeds about 25%, the blend takes on the characteristics of a thick slurry, requiring a supplemental sensitizer in the slurry  per se. Slurries containing a nitrogen-base salt of an inorganic oxidizing acid, preferably monomethlamie nitrate, are preferred because this additive affords a saturated solution with lower water content, and also can act as a sensitizer.

Abstract: ABSTRACT OF THE DISCLOSURE        The medical container of the present application is designed to provide a simple method and structure for the disposal of medical needles, of the type for taking blood samples and similar applications.  Needles of this type have a steel or metal shank portion through which the blood or liquid is drawn, a plastic collar intermediate the length of the steel shank for releasably engaging a barrel portion with a portion of the needle extending interior to the barrel.  The needles are released from the barrel by screwing the plastic collar out of the barrel. The container assists in this operation and includes a needle release area, preferrably a sunken recess, which has a needle receiving port having an enlarged area through which the needle and collar may pass and a restricted area for gripping the front portion of the plastic collar on the needle.  The needle release area is shaped to provide the user with a mechanical advantage by using the barrel portion as a lever, forcing the collar into the restricted area of the needle release area in a manner to grip the collar and hold the same such that the barrel may be rotated to cause release of the needle. After the screw thread of the collar has been released from the barrel, the needle is then passed through the enlarged area, whereupon the needle falls through the enlarged area into the closed confines of the container.

The servo-reference level, in operation of the device, is adjusted by opening the closed loop of the control circuit for a short interval, after which, in open-loop operation the cuff pressure is adjusted at an intermediate pressure derived from the pressure last measured and the servo-reference level is adjusted via the memory circuit.
