Granted: 1998-12-22
Abstract: Interactive Methods and apparatus for studying similarities of values in very large data sets. The methods and apparatus employ a dotplot in an interactive graphical user interface to make the relationship between the similarities and the data set visible. A variety of filtering, weighting, and compression techniques make it possible to employ the dot plot with sequences of more than 10,000 tokens and tointeractively magnify the dot plot, change weighting and display quantization, and view the underlying data. Also disclosed is a technique which is employed in theapparatus for identifying long sequences of similar tokens. The apparatus is used in the study of large bodies of text and code.

Title: Convertible guidewire catheter with soft tip
Inventor: ALVAREZ DE TOLEDO FERNANDO
IPC: A61M25/00
Filed: 1991-10-28
Granted: 2003-04-08
Abstract: A convertible wire for use as a guidewire or a catheter in medical applications, The convertible wire comprises a coil spring structure (21) that extends over a proximal portion (11) and a distal tip portion (13). The spring pitch at the distal tip portion is greater than the spring pitch at the proximal portion to provide greater flexibility at the distal tip portion. A polyimide sheath (30) surrounds the proximal portion of the spring for increased strength. An outer polytetratluoroethylene sheath (40) overlies the po-lyimide sheath and the coil spring in the distal tip portion so the distal tip portion constitutes an atraumatic soft, floppy tip that readily travels through passages in the body.

Title: Process for producing methyl formate
Inventor: YONEOKA MIKIO
IPC: C07B61/00
Filed: 1994-05-16
Granted: 2004-04-27
Abstract: There are disclosed a process for producing methyl formate by dehydrogenating methanol in liquid phase in the presence of a solid catalyst and a process according thereto wherein a gas (N2, H2, CO, etc.) is continuously blown into the liquid phase from outside, and the gas along with the reaction product are continuously withdrawn outside the reaction system from the gaseous phase directly or through a cooler. By virtue of the liquid-phase reaction in the above process, as compared with the conventional gaseous phase reaction, the reaction temperature can be lowered, the reaction gas rich in the objective methyl formate rather than methanol is obtained by continuously withdrawing the resultant methyl formate outside the reaction system and accordingly, a single pass yield higher than that at the thermodynamical equilibrium-value is assured, whereby energy saving is made possible.

Abstract: The defrosting of a heat transfer unit of a temperature conditioning system is controlled by initiating a defrost operation when a predetermined amount of frost has accumulated on the unit during a period between defrost operations. A known desired defrost time period is required to defrost the unit when it has the predetermined amount of accumulated frost thereon. The time required to actually defrost the unit during a first defrost operation is measured to form a first defrost time. The time required to actually defrost the unit during a second defrost operation is measured, the second defrost operation is the next defrost operation following the first defrost time and forms a second defrost time. The frost accumulating period is modified in response to said first defrost time and said second defrost time.

Title: Distributed systems with replicated files
Inventor: RAO CHUNG-HWA HERMAN
IPC: G06F17/30
Filed: 1995-06-23
Granted: 2000-04-18
Abstract: Techniques for providing replicated files in a distributed system. A replicated file has a set of copies in components of the distributed system. Operations on the copies have the same semantics for the application processes accessing them as operations on a single copy of a file in a system where all processes execute on the same host. These semantics are achieved by means of a distributed synchronization system. Each replicated file has a read token and a write token. In order for an application process to perform an operation on a replicated file, the token required for theoperation must be in the process's host and the process must have access to the token. Tokens are passed between hosts by token servers which respond to requests for tokens from application processes and from other token servers. The techniques are implemented using a library which replaces a standard I/O library, and may thus be employed without modification to hardware or the operating system.
