Title: Microstructurally refined multiphase castings
Inventor: DOLMAN KEVIN FRANCIS
IPC: C22C37/06
Filed: 1994-05-20
Granted: 2009-12-08
Abstract: The present invention relates to eutectic alloy systems, such as white irons, in which a primary phase grows out of the melt when the melt is cooled below the liquidus temperature and comprises pouring the molten metal alloy at a temperature at or above the liquidus in a stream into a casting mould to form a casting and introducing a particulate material into the stream of molten metal to extract heat from the molten metal alloy to undercool the molten metal alloy from the pour temperature into the primary phase solidification range between the liquidus and the solidus temperatures of the alloy and thereby initiate primary phase nucleation and restrict primary phase growth. The primary function of the particulate material is to act as a heat sink but the particulate material may at least partially dissolve in the melt and may act as a seeding agent for the primary phase. The invention is described with particular reference to high chromium hypereutectic white irons.

The electrical splices each comprise a splice conductor connecting the rails together at opposite ends of each track segment, and having an "S" shape laid flat and extending along the longitudinal axis of the track. Each splice conductor has axially-extending branches arranged along internal sides of corresponding rails. The track circuit comprises a stationary ground transmission unit and a stationary ground reception unit for each track segment, and corresponding on-board mobile reception units on trains in transit along the track. The stationary ground transmission units transmit data to and receive data from the on-board units through the rails of a corresponding track segment when a train travels on the corresponding track segment. Each track segment is connected to a compensation network comprising a plurality of capacitors connected to the rails of that track segment. Transmission of the data by the stationary ground units takes place at an audiofrequency range frequency, and using Minimum-Frequency-Shift-Keying modulation/demodulation; the data being coded as digital signals. The track circuit further comprises six transmission/reception channels for transmission and reception of data, each of those channels having a different carrier frequency and an identical preset bandwidth. The six transmission/reception channels comprise a first three transmission/reception channels for transmission/reception on a track associated with a first train-travel direction, and a second three transmission/reception channels for transmissions/receptions on a track associated with a second, opposite train-travel direction.

Abstract: A cargo carrier assembly (or "carrier") is externally carried at the rear of a truck. The carrier comprises a frameless L-shaped rack in combination with a wheeled container specifically adapted to be pivotably loaded onto the rack by using pivot latches which matingly receive locking pins fixedly secured to the container. The rack comprises either a single integral L-shaped support beam, or a compoundbeam.  The compound beam, in turn, comprises a combination of (a) a pivot strut one side of which is attached to the frame of the truck and (b) an integral L,shaped support beam comprising a transverse strut and a longitudinal strut upon which latter strut only, the container is pivotably disposed. Only a portion of the base of the container is either directly supported on the struts of the L-shaped rack or supported on pivot pins. Though the container may be secured with only two pivot latches, it is preferred to use, in addition, an attachment latch. The width of the wheeled container is chosen so that it can be rolled in an inclined position through a doorway of a conventional dwelling, and the length is chosen so that, when loaded on the rack the container does not obscure the tail-lights of the truck.

Title: Thermal protector for electric motors
Inventor: KOSEKI HIDEKI
IPC: H02K11/00
Filed: 1997-06-27
Granted: 2001-11-06
Abstract: A thermal protector includes a header plate and a metal housing having an open end hermetically welded to an peripheral edge of the header plate.  The housing is formed into a generally slender shape so as to be suited for mounting on end turns of a stator winding of a three-phase electric motor.  A thermally responsive element includes a shallow curved portion at which the element changes states of curvature with snap action in response to different ambient temperatures.  The thermally responsive element has two movable contacts secured to it to be disposed symmetrically about a center of the curved portion so that the movable contacts are engageable with and disengageable from fixed contacts respectively.  A push piece is disposed in the housing to exert a pushing force on a normally convex side of the thermally responsive element.  The pushing force is adjusted by deforming the outer surface portion of the housing for calibration of the operating temperature.  The push piece includes a portion secured to an inner surface of the housing so as to correspond substantially to the deformed outer surface portion of the housing for calibration of the operating temperature.

Abstract: L'invention concerne de nouvelles méthodes de diagnostic sans biopsie d'affections bénignes de la prostate (BPD), telles que l'adénome prostatique, la prostatite ou l'atrophie glandulaire chez un patient humain de sexe masculin. On mesure le taux d'antigènes totaux spécifiques à la prostate (PSA) dans le sang ou le sérum du patient. Si ce dernier présente un taux de PSA totaux compris entre environ 2,5 ng/ml et 10,0 ng/ml, on mesure alors le niveau de PSA libres dans le sang ou le sérum du patient. On calcule la proportion de PSA libres par rapport à celle de PSA totaux. Si cette proportion est supérieure ou égale à environ 25 %, on considère que le patient souffre de BPD. Eventuellement, si le patient présente un taux de PSA compris entre 10,1 ng/ml et 20,0 ng/ml, on peut également mesurer le taux de PSA libres dans le sang ou le sérum du patient. On calcule la proportion de PSA libres par rapport à celle de PSA totaux. Si cette proportion est supérieure ou égale à environ 25 %, on considère que le patient souffre de BPD.

Title: Fault data collection as part of computer unit restart
Inventor: TATTARI LAURI
IPC: G06F11/00
Filed: 1996-10-29
Granted: 2006-02-14
Abstract: In problem situations of a computer controlling a process, such as transmission of calls, it is very important to direct the maintenance operations in the correct manner at the correct places as rapidly as possible. In the fault data collection method according to the invention, fault data is collected selectively by using empirical data about what type of information is useful in solving problems. Data (P10A - P40A) about each process family is searched for from the list of process families PL in the data area (DA) of the computer's operating system. By means of the first process (P10) of the process family, data is obtained about the other processes (P11 - P14) of the family. The data structures (PA) of the processes (P10 - P14) provide data about the memory resources reserved by the process, time supervision, etc.. By comparing the content of the data structures (PA) to the empirical base values, data structures (PA) are copied to the storage area (SA) from the processes that are to be examined in greater detail. The data structures are collected after the restart has been activated but before new data has been written into the part of the main memory where these data structures (PA) are stored.
