Title: Vacuum security valve having a buffer volume
Inventor: PEACOCK ROY N
IPC: F16K31/42
Filed: 1988-07-18
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE     A vacuum security valve includes a buffer volume in a movable piston.  The movable piston has two orifices communicating with the buffer volume, the first orifice communicating with a clearance volume above the piston.  A flexible diaphragm is connected to the piston for separating the clearance volume from the remainder of the interior of the valve body.  Another orifice, disposed to communicate with the remainder of the interior of the valve body rather than with the clearance volume, is provided in the piston wall, and also communicates with the buffer volume.  A solenoid operated valve, which is normally in the opened position, communicates through the valve body with the clearance volume, and also communicates with a vent.  The security valve is connected at one port to a vacuum system which is to be protected upon power failure of a vacuum pump.  The other port of the security valve is connected to the lines leading to the vacuum pump.  Upon failure of power to the vacuum pump, or upon shutdown, the solenoid operated valve moves to its open position, venting the clearance volume and causing movement of the piston downwardly against a seat, thereby substantially preventing influx of air into the vacuum system.  The orifices in the movable piston permit equalization of pressure during venting so that the vacuum pump, vacuum pump lines, buffer volume, and clearance volume are all at ambient pressure.  In another embodiment, the buffer volume is disposed outside of the valve body, with the movable piston being solid.     In this embodiment, the external buffer volume communicates via two orifices with the interior of the valve body, one orifice being above the diaphragm and the other below the diaphragm.

Title: Virtual lookaside facility
Inventor: BROWN DAVID D
IPC: G06F12/12
Filed: 1989-05-18
Granted: 1993-01-12
Abstract: VIRTUAL LOOKASIDE FACILITY           ABSTRACT      A virtual lookaside facility is provided for maintaining named data objects in class-related data spaces in virtual storage, readily retrievable by user programs.  A search order is associated with each user, specifying an ordered list of "major names" which are, in effect, sequentially searched for a specified "minor name", or data object, to obtain a virtual storage copy of that data object.  As data objects are placed into a virtual cache, existence information, implicit in the naming structure, is captured and saved.  This information is relied on later in retrieving objects from the cache.  The data isolation provided by maintaining class data and control blocks in individual data spaces is exploited to prevent failures relating to one class of objects from affecting the others, and to handle latent program users, following failures, effectively.      An LRU-like trimming technique is used to remove less useful objects from the cache when cache space is fully utilized.

Title: Mechanically locking blood clot filter
Inventor: PALESTRANT AUBREY M
IPC: A61F2/01
Filed: 1989-07-06
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE          A blood clot filter particularly suited for filtering blood clots from blood circulating through the inferior vena cava is composed of a number of peripheral wires joined at one end by a first connector and also joined approximately at their middle portions by a second connector.  The wire portions extending between the two connectors form a filter mesh, and the wire portions extending between the second connector and the free ends form filtering legs which anchor the filter.  The free ends have recurved hooks for radial engagement with a blood vessel.  The filter mesh is formed by mechanically approximating the two connectors resulting in the formation of overlapping loops of wire.  A central core wire is fixedly secured to one of the two connectors and slidingly extends through the second of the two connectors.  The central core wire is retracted to slide the two connectors together.  A lock device prevents the two connectors from sliding back apart.  The wire strands may initially be substantially straightened in order to permit insertion of the filter into the lumen of an angiographic catheter.  The catheter is positioned at a predetermined site within the vessel using standard percutaneous angiographic techniques from the groin or neck.  A pusher catheter extending within a delivery catheter pushes the filter out of the delivery catheter and into the lumen of the blood vessel.  A retractor cable extends through the pusher catheter and is releasably coupled to the central core wire for retracting the same.  Once the filter has been delivered into the blood vessel and the filter mesh mechanically formed, the legs are released to anchor the filter in position, and the pusher wire is disconnected.

Abstract: METHOD FOR PRODUCING FREQUENCY MATCHED SETS      OF composite GOLF CLUB shafts ABSTRACT    In the production of a matched set of golf clubs, the most accurate method for matching the flex of each shaft in the set is through the use of an electronic frequency analyzer which measures the vibrational frequencies of the shafts or clubs.  With most high quality steel shafts, such frequency measurements are generally reproducible and serve as a reliable index of shaft flexibility  It has been found for some shafts, particularly for composite shafts, that frequency measurements taken along different cross-sectional diameters may vary.  For such shafts, it has been found that frequency measurements will be reproducible, if the frequency measurement is made on the same diameter.  The diameters used for such measurements are marked on the shaft and then employed in the construction of the golf club, such that the diameter is substantially perpendicular to the striking face of the club head.
