Title: Method and apparatus for adjusting the position of stabilizer blades
Inventor: JOHNSON HAROLD D
IPC: E21B17/10
Filed: 1993-10-21
Abstract: A telemetering system is disclosed for communicating command signals to a downhole adjustable blade stabilizer, and for transmitting encoded time/pressure signals back to the surface. The command signal provides information regarding a desired blade position for an adjustable blade stabilizer. The stabilizer sets a positioning piston in response to the command signal to limit the extent of blade expansion. A  measuring means is provided in association with the positioning piston to measure precisely the position of the blades. An encoded signal is generated in response to the measurement and is transmitted to the surface in a combined time/pressure format to uniquely identify the position of the blades.

Title: Bag-in-carton and pouring spout thereof
Inventor: SASAKI YASUYUKI
IPC: B65D5/56
Filed: 1993-10-27
Abstract: A pouring spout 5 is mounted on the front surface of a carton 2. The pouring spout 5 pierces through an inner bag. Only a region which is slightly larger than the half of the inner bag 3 on the pouring spout side is adhered to the inner surfaces of the carton by a paste.

IPC: F24D3/10
Filed: 1993-10-28
Abstract: A method and device for maintaining a fluid at a working pressure in a substantially closed fluid circulation system wherein the temperature of the fluid can vary and which is preferably deaerated continuously. The maintenance of a working pressure is realized by keeping the system filled automatically by connecting said system, by means of a closable connection, to a stock of fluid which is under atmospheric pressure, the fluid circulation system and the stock of fluid being connected directly, which connection is opened at and below atmospheric pressure at the location of the connection and, when the working pressure rises, is automatically closed at atmospheric pressure at the location of the connection.  If so desired, replenishment of the stock of fluid, which is preferably disposed in the vicinity of the highest point of the system and may serve as expansion possibility for the system, may be effected automatically.

Title: High conductivity hybrid material for thermal management
Inventor: KIBLER JOHN J
IPC: H01L23/373
Filed: 1992-12-14
Abstract: A hybrid structural material (10) combines high thermal conductivity and predetermined mechanical properties compatible with adjacent materials. It has three elements: (1) a non-structural, high thermal conductivity core material (20) which defines the thermal conductivity of the hybrid structural material; (2) a pair of face sheets (30, 40), which form opposing surfaces of the hy-brid structural material and help to define its mechanical properties, disposed on opposite sides of the core material to create a face sheet-core material-face sheet sandwich construction; and (3) a frame (50) substantially surrounding the core material and bonded to the face sheets for helping to define (along with the face sheets) the mechanical properties of the hybrid structural ma-terial. The interfaces (70, 80) between the face sheets and the core material allow physical contact, but prevent structural interac-tion, between the face sheets and the core material. Consequently, the hybrid structural material achieves a high fraction of the thermal conductivity of the core material while maintaining the thermal expansion (and other mechanical properties) of the face sheets and frame.
