    Abstract: A rotary valve having a rotary member with an outer surface forming at least a segment of a sphere. A passage extends through to opposite sides of the segment. An annular recess is in the segment abutting and surrounding each end of the passage. A housing rotatably mounts the rotary member therein and has a passage therethrough comprising a passage portion that is alignable with the rotary member passage and has a larger perimeter than the inside perimeter of the recess. A pair of resilient annular seals are fixed in between the housing and rotary member. One seal is around each end of the segment passage. The seals extend into the housing member passage into abutting sealing engagement with the annular recesses. A process is disclosed for making the aforementioned valve by mounting the seals and rotary member on a core and inserting the resultant assembly in a mold and preloading the seals while molding molten material therearound to form the housing. A product made by the aforementioned process is also disclosed.

    Abstract: A SOLID MATERIAL IS FORMED OF AN AT LEAST SLIGHTLY WATER SOLUBLE POLYMERIC ACID AND A CARBONATE. WHEN THE SOLID MATERIAL IS PLACED IN A CONTAINER OF WATER, THE ACID AND CARBONATE REACT TO EVOLVE CARBON DIOXIDE AND A SUBSTANTIALLY WATER INSOLUBLE SALT. THE PHYSICAL INTEGRITY OF THE SOLID MATERIAL IS NOT DESTROYED BY THE REACTION.

    Abstract: Cryosurgical apparatus feeds liquid refrigerant to the hollow tip of a cryosurgical probe through a first conduit to freeze the tip, the refrigerant exhausting from the tip through a second conduit. To defrost the tip, refrigerant in the second conduit is heated and then back-flushed through the tip so that it exhausts therefrom through the first conduit. To maintain proper fluid flow through the probe during the defrost mode of operation, the probe contains a third conduit which bleeds fluid from the tip during both modes of operation.

    Abstract translation: 冷冻手术装置通过第一导管将液体制冷剂供给到冷冻手术探针的中空尖端，以冻结尖端，制冷剂通过第二导管从尖端排出。 为了使尖端除霜，第二导管中的制冷剂被加热，然后通过尖端反冲洗，使得其从第一导管排出。 为了在除霜操作模式期间保持适当的流体流过探头，探针包含在两种操作模式期间从尖端流出液体的第三导管。

    Abstract: A CARBONATED BEVERAGE IS FORMED BY DILUTING A CONCENTRATED CARBONATED SOLUTION CONTAINING 15-75% BY WEIGHT SUGAR, 85-25% BY WEIGHT WATER, AND MORE THAN 6 VOLUMES OF CARBON DIOXIDE. A FLAVORING AGENT MAY BE INCLUDED WITHIIN CONCENTRATE. THE CONCENTRATE IS DILUTED BY POURING IT THROUGH AIR INTO WATER WITHOUT JET ASSISTANCE OR BY POURING WATER THROUGH AIR INTO THE CONCENTRATE.
