Title: Ultrasonic treatment system
Inventor: VAGO ROBERT E
IPC: A61H35/00
Filed: 1993-10-27
Abstract: ULTRASONIC TREATMENT SYSTEM            ABSTRACT OF THE DISCLOSURE    To provide ultrasonic cleaning of inanimate objects, ultrasonic waves in a frequency range of between 15 kilohertz and 10 megahertz are applied to water in a tank with a power density between 15 and 7,000 watts per square centimeter. Asymmetric power waves are applied to avoid instability leading to transient  cavitation.    To  provide  ultrasonic treatment  of  animals,  ultrasonic  waves  in  a frequency range of between  15 kilohertz  and  500 kilohertz are applied to water in a tub with a power density  between  0.1  and  5  watts  per  square centimeter.    The  equipment  is  able  to  apply ultrasonic waves with at least two power densities in the vicinity of the portion of the animal with one of said power densities being more than 15 watts per square meter for sterilizing the water before the patient enters the tub and the other being less than 15 watts per square meter.

Title: Retractable gas injection pin for injection mold
Inventor: DANIELS VERNON A
IPC: B29C45/17
Filed: 1992-06-10
Abstract: An improved injection molding system wherein gas is injected through an injection pin (56) associated with an ejector pin (52).  The injection pin is movable between a retracted position at which it is sealed from the mold cavity (26), to an extended position where it delivers gas into the cavity. Two distinct embodiments are disclosed. A first injection pin is powered by a cylinder (54) to move between the extended and retracted positions. In a second embodiment, the injection pin is actuated by the pressurized gas. The improved systems inject gas into a mold cavity without the requirement of a separate injection aperture. Further, the inventive injection pins have outlet ports (83) sealed from the flow of plastic until the injection pin is extended to deliver the gas.

Title: Controlled action self-mixing vial
Inventor: HABER TERRY M
IPC: A61J1/05
Filed: 1992-07-23
Abstract: A controlled action mixing vial (2) includes an elongate mixing container (14) having a movable piston (18) and fluid pressure rupturable seal (20).

Title: Method for measuring formation fluids in drilling fluid
Inventor: AMEN RANDALL M
IPC: E21B49/00
Filed: 1993-04-09
Abstract: In a well drilling operation (10), drilling fluid (70) is used to remove rock cuttings (68) and associated formation fluids released by the drill bit (84) and transport them to the surface. At the surface, a portion of these cuttings and fluids is extracted from the drilling fluid (70) for analyses. The resulting data are used in formation evaluation. This method shows how to determine the concentrations of specific formation fluids in the drilling fluid by adding and maintaining select foreign substance of controlled concentration to the drilling fluid as a reference fluid (64), and factoring the returned formation fluids by the reference fluid. The method also shows how the technique is used as a means to assure quality control of the measuring system and as a non-disruptive means to measure lag.

Title: Edging block and method of enclosing an area utilizing a series of edging blocks
Inventor: DEAN ROBERT W JR
IPC: E01C11/22
Filed: 1994-06-28
Abstract: A landscape edging or border block has an essentially trapezoidal shape, and is capable of being used to form a linear, serpentine or combination border or edge.  The blocks can also be used to enclose an area. By orienting each block such that its inner edge faces inwardly, a substantially circular shape is attained to enclose a circular area.  To expand the area to be en-closed, at least two expansion blocks are added for each quadrant of the shape.  The two expansion blocks are oriented so as to provide a linear segment in each quad-rant between adjacent ends of each arcuate segment. Additional pairs of expansion blocks can be added for each quadrant to further expand the area to be enclosed. In all cases, the enclosed area is formed by placing adjacent blocks such that their edges engage each other to form a shape without the presence of gaps between adjacent blocks.
