Title: Attachment for thermal probe
Inventor: ROCK JEFFREY ALLAN
IPC: F02B77/08
Filed: 1994-05-27
Granted: 1997-10-14
Abstract: A twist lock for attaching a plastic shell of a thermal probe to a structural member such as a plastic intake manifold of an internal combustion engine in a socket in the structural member. The twist lock includes hooks on the plastic shell which traverse an annular shoulder at the bottom of the socketthrough notches in the shoulder when the shell is inserted in the socket and which are captured by the shoulder when the shell is rotated in the socket from an unlocked position to a locked position. The twist lock further includes a lugon the shell cooperating with a cam edge on a resilient lip around an open end of the socket to afford tactile representation of the progress of the shell toward and achievement of the locked position and to prevent reverse rotation of the shell from the locked position.

Granted: 1998-02-17
Abstract: Apparatus and methods for improving signal detection and tracking in underwater acoustic devices receiving a set of acoustic pulses propagated in response to repetitive synchronizing events. Each of the set of pulses is correlated with a replica of each pulse in a receiver in the underwater devices during an associated time window. The correlated output of the receiver is compared to an adjustable threshold characteristic in a detector for selection of the actual pulse according to predetermined criteria for each of the set of pulses. An actual time of reception relative to the synchronizing event is assigned to the selected pulse. Previous actual times of reception are used to estimate the expected time of reception of the associated pulse relative to the next synchronizing event. The estimate is used to adjust the associated time window to encompass the expected time of reception. Previous actual times of reception are compared to corresponding estimated times of reception to develop a measure of the quality of the estimates. The shape of the threshold characteristic and the width of the associated time window are adjusted as a function of the measure of the quality. A preferred threshold characteristic has a parabolic shape with its vertex defining a minimum threshold level at the expected time of reception. High quality measures lower the minimum threshold and narrow the parabola and the time window; low quality measures raise the minimum threshold level and broaden the parabola and the time window. Adaptive signal tracking is thereby provided.

Filed: 1994-02-28
Granted: 2007-01-02
Abstract: A novel polysaccharide derivative, a drug carrier comprising a novel polysaccharide derivative, and a drug complex are disclosed. The polysaccharide derivative according to the present invention comprises a polysaccharide having a carboxyl group in which a peptide chain is introduced at a part or all of the carboxyl groups of the polysaccharide. The peptide chain comprises 1 - 8 amino acids which may be the same or different. A part or all of the amino groups in the peptide chain which are not involved in the linkages with the carboxyl groups of the polysaccharide or the carboxyl groups in the peptide chain may form an acid amide linkage or an ester linkage with a carboxyl group, an amino group or a hydroxyl group of a third compound such as drugs. The polysaccharide derivative has property of highly accumulating to tumor, and thus can deliver efficiently a drug which has a side-effect or a limited sustainment of the drug efficacy to the tumor.

Abstract: A billet of steel has a composition comprising small amounts of hardenability agents.  The billet is hot rolled into a continuous bar, in two hot rolling stages with an intervening cooling step employing a turbulent cooling liquid.  After the second hot rolling stage, the bar is gathered into a succession of closely overlapping loops and moved along a roller conveyor where the overlapping loops are cooled by air blowers, after which the bar is coiled.  The resulting hot rolled bar has a microstructure consisting essentially of bainite in fine-sized packets reflecting an average austenitic grain size, before the gathering and cooling steps, of 8-11 ASTM.  A threaded fastener in its final form can be produced from the hot rolled bar by a cold deforming operation without a heat treating operation before or after cold deforming.  The threaded fastener is undistorted and contains residual compressive stresses.

Abstract: A physically realizable one terabit or more ATM packet switch that has a large number of input interfaces connected to a single stage switching fabric which is in turn connected to a number of output modules, generally according to the growable packet switch architecture. This ATM packet switch is different from other growable packet switches in that it has a single stage switch fabric controlled by an out-of-band controller, yet it has significantly reduced complexity with respect to comparably sized electronic crossbar switches or their isomorphs. The out-of-band controller has multiple priority levels in order to provide high priority users with a near certainty that their packets will be successfully routed, while delivering an acceptably low packet or cell loss probability to users at the lowest priority level.

Title: Method of operating a computer system
Inventor: MALCOLM PETER BRYAN
IPC: G06F21/12
Filed: 1995-09-06
Granted: 2006-05-30
Abstract: In an improved method for accessing files in a computer system, file open requests (20) are intercepted at the level of the operating system. The identity of the file to be opened is extracted (22) from the request and a determination (24) is made as to whether the identity of the requested file should be replaced with the identity of a substitute file to be opened instead of the requested file. If it is determined that the identity should be so replaced, the file open request is amended by substituting (26) the identity of the substitute file for the identity of the requested file, and the request is passed on to its original destination for execution. This technique can be used to cause execution of a substitute program without the knowledge of the user. As an example, software metering can be implemented in a network system by substituting a different program from that requested when the number of copies of the requested program in use on the network has reached the maximum licensed number, so as to provide a user-friendly rejection of the program execution request.

Abstract: New biodegradable polyanhydrides  are disclosed, which are prepared by homopolymerization of dimer of bile acid, especially lithocholic acid, or bycopolymerization with linear dicarboxylic acid,  especially sebacic acid.  These biodegradable polyanhydrides have degradation kinetics and a release rate that make them particularly useful for controlled drug release. More specifically, the degradation kinetics of such anhydrides and the release rate of molecules embedded therein make them useful as matrices for controlled drug release systems.  The rates of degradation and release can be adjusted by the copolymer composition.  The near zero-order kinetrics of release of the drug embedded in the matrices made of such anhydrides, make the same particularly useful since they can deliver an active ingredient at a constant rate for long period of time,  avoiding the inauspicious saw-tooth pattern of conventional systemic administration.
