Title: Valve control apparatus
Inventor: TWERDOCHLIB MICHAEL
IPC: G05D7/06
Filed: 1992-05-28
Abstract: 56,202 ABSTRACT OF THE DISCLOSURE         The present invention provides a valve control apparatus which can be programmed to deliver a desired flow of gas.  A valve 22 is connected to a stepper motor 28 which is controlled by a computer 32 to open or close the valve in steps within a gas flow line 24 to deliver a desired rate of flow.  A flowmeter 30 is provided along the gas flow line 24 for measuring the flow and inputting this flow to the computer 32.  The computer 32 calculates rate of flow information obtained from the flowmeter 30 and controls the stepper motor 28 to open or close the valve 22 as necessary in accordance with the received rate of flow information and a desired rate of flow preprogrammed into the computer 32.  As a result, a precise desired rate of flow can be obtained.  Also, position indicators 34 may be added to the valve 22 to indicate when the valve 22 is completely open or completely closed.  The valve 22 may be provided with a return spring 36 to automatically close the valve 22 in the event of a power loss.  the computer 32 may be programmed to detect a significant increase in the rate of gas glow begin closing the valve 22 accordingly. Additionally, a pressure switch 38 may be provided along the gas flow line 24 to cause the valve 22 to close upon a pressure change.  Finally, temperature 40 and pressure 42 sensors may be added along the gas flow line so that the computer 32 can calculate and maintain a specific mass flow of gas.

Title: Actuator with automatic lock
Inventor: SMITH DENZIL B
IPC: F16K31/122
Filed: 1990-12-11
Abstract: An improved blowout preventor actuator (20) is provided for opening and closing a ram block (26) within a blowout preventor body (12) to control the flow of well fluid. The working or power piston (30) within the actuator cylinder (46) is provided with one or more axially extending cavities (68) each for receiving a locking rod (42) secured at one end to the cylinder head (32). To prevent inadvertent opening of the ram block (26), locking segments (92) carried by the power piston (30) repeatedly disengage one locking surface and re-engage an adjacent locking surface on the locking rods (42) as the power piston (30) and ram block (26) secured thereto move to the ram closed position. To unlock the power piston (30) from the locking rods (42), fluid pressure is applied to an unlocking piston (80) which radially moves the locking segments (92) out of engagement with the locking rods (42). The locking surfaces on the locking rods (42) extend axially along a length which allows different ram blocks (26) to be substituted for sealing with various diameter tubular members (16) passing through the blowout preventors (10). The simple yet highly reliable technique for preventing opening of the BOP ram block (26) increases safety and reduces manufacturing and operating costs.

Patent CA-2082841-A1 (CA)
Inventor: TSUZUKI MUNENORI
IPC: H04L47/22
Filed: 1992-11-13
Abstract: An ATM cell exchanging apparatus includes an ATM cell switch for a first system #1 and an ATM cell switch for a second system.  These cell switches distribute input cells to appropriate output lines.  The system also includes selectors for switching the ATM cell switches in accordance with a selection signal that is output from an external system.  The ATM switches output an idle cell when there is no cell to be output.  When the selector judges that it is necessary to switch the systems as indicated by the change-over signal, the selector switches the system after it confirms that an idle cell is output from both ATM cell switches.  The idle cell that is output indicates that there is no cell stored in either system; thus, it is easy to switch the systems without causing the duplication or omission of a cell.

Title: Balloon catheter with distal guide wire lumen
Inventor: KEITH PETER T
IPC: A61M25/06
Filed: 1991-08-27
Abstract: An over-the-wire balloon dilatation catheter (20) has a stainless steel hypotube catheter shaft (22), an intermediate sleeve section (24) banded to the shaft (22) and a distal balloon section (25) connected to the sleeve section (24). The sleeve section (24) is formed from relatively flexible polymer materials and includes an inner core tube (80) which defines a guide wire lumen (52) extending only through a distal portion of the catheter (including its sleeve and balloon sections) to facilitate fast balloon catheter exchanges. A distal end (30) of the hypotube shaft is crimped laterally and the core tubs (80) is nested and bonded within the crimp to provide a proximal outlet for the guide wire lumen (52). The hypotube shaft (22) provides an inflation lumen (62) for the balloon, with the inflation lumen (62) being continued as an annular inflation lumen through the sleeve section (24) where an outer sleeve (82) is bonded about the core tube (80) and extends from the distal end of the hypotube shaft to the balloon section. A kink-resistant coil structure (110) extends distally from the distal end (30) of the hypotube shaft (22) to provide a gradual change in stiffness along the length of the catheter (20) from the relatively stiff hypotube shaft (22) to the relatively flexible distal portion of the catheter.

Title: Process and apparatus for manufacturing low-gas and pore-free aluminum casting alloys
Inventor: LORENZ HEINZ
IPC: B22D11/08
Filed: 1993-03-17
Abstract: ABSTRACT OF THE DISCLOSURE            The  invention relates to a process and apparatus  for manufacturing low-gas and pore-free aluminum casting alloys by vacuum treatment of the melt.   Contact between the aluminum melt and the atmospheric humidity of the alloying process, from refining to continuous casting of the cast bars,  is kept extremely short, so that environmentally-friendly and effective vacuum degasification, and a high cooling rate,  can prevent the formation of gas pores. After the metal melt is alloyed in a smelting furnace, the melt is fed through a system of gutters directly to at least one vacuum furnace.  Refining components are added in the vacuum furnace and the pouring temperature required for continuous casting is adjusted.  The vacuum in the vacuum furnace is maintained to degasify the melt and increase the density thereof, such as for an additional 5 to 240 minutes with periodic measurements of the metal density, and the metal melt is then fed through the gutter system directly to the continuous casting mold.

Inventor: PARKER DAVID M
IPC: F01D25/24
Filed: 1993-03-26
Abstract: 57, 064 ABSTRACT OF THE DISCLOSURE A plate  for spreading bolt  loading around the horizontal joint flanges of a turbomachine, such as a steam turbine, is provided.   The plate is contoured so that its surface area substantially matches that of the surface of the steam turbine  flange against which the compressive load associated with the joint bolt preloading is applied.  The plate is disposed between the flange and the nuts on the joint bolts and is made from a high yield strength material so that the locally high stresses under the nuts do not cause creeping or yielding of the plate.  The plate serves to distribute the compressive joint loading around the entire surface of the flange,  thereby eliminating the locally high compressive stresses that can cause creep and yielding in the flange. Spherical counter bores are machined in the plate bolt holes and spherical washers are installed between the plate and the nuts so that misalignment of bolt holes does not cause the nuts to impose bending forces on the bolts.
