Title: Connecting a shaft to a bore
Inventor: MORELLI PETER ALAN
IPC: F16D1/08
Filed: 1993-07-27
Granted: 2003-09-30
Abstract: A shaft 44;144,145 is conventionally driveably connected to a bore1 46,146 by a steel key of rectangular cross-section. Where the shaft is of smaller diameter than the bore, a slotted nylon sleeve is fitted between them and a tall steel key extends through the slot. Failure of both standard and tall keys can occur for various reasons. A unitary component 50,162,163 of suitable plastics material or non-ferrous metal is therefore proposed. This component essentially includes an integral key 56,174 of curved cross-section adapted to engage in a mating keyway 176 formed in the bore. Where the shaft 44 and bore 46 are nominally of the same diameter, the component 50 consists also of an integral key 52 of rectangular cross-section adapted to engage in the conventional keyway 48 in the shaft. Where the shaft 144, 145 is of smaller diameter than the bore 146, the component 162, 163 also includes a sleeve 164 with the key 174 of curved cross-section formed on its outer periphery, and a keyway 170 of rectangular cross-section formed in its inner periphery and adapted to be driveably connected by a separate standard key 171 to the conventional keyway 148,149 in the shaft. The component is useful in the flange-mounting of different electric motors on off the-shelf gear units.

Abstract: A method for assessing the fracture pressure closure is proposed. This method includes first injecting a fluid into the formation at a first generally constant rate Q to create a fracture, and then, dropping the pumping rate to significantly smaller feed rate q so that the volume of the fracture becomes constant, in other words. As the fracture volume becomes constant at equilibrium, the well is shut-in. The wellbore pressure is monitored and the closure pressure is determined from the analysis of the wellbore pressure using a time-function of the dimensionless "shut-in" time, defined as the ratio of time since shutting to pumping time. This method provides a way of estimating the friction component of the monitored wellbore pressure due to the fracture tortuosity and friction. It is applicable to the art of fracturing subterranean formations and more particularly to the process of designing and analyzing stimulation treatments.

Abstract: Il s'agit d'un mécanisme de support à aide verticale et fermeture souple pour une porte d'armoire qui s'ouvre par déplacement vers le haut puis vers l'arrière, jusqu'à une position partiellement horizontale au-dessus de l'armoire. Ce mécanisme comprend des paires de biellettes de longueurs inégales sur les parois opposées de l'armoire. Une de ces biellettes est conçue en levier coudé. Une bouteille à gaz est accouplée entre un bras du levier coudé et la paroi d'extrémité de l'armoire, tandis que le second bras du levier coudé est raccordé à la porte. Lorsqu'un utilisateur commence à ouvrir la porte, la bouteille à gaz exerce un mouvement de rotation autour du levier coudé, ce qui facilite le mouvement d'ouverture de la porte.  l'inverse, lorsqu'un utilisateur commence à fermer la porte, le levier coudé tourne en sens contraire et exerce une force de compression sur la bouteille à gaz, ce qui permet d'obtenir une fonction de fermeture souple.

Title: Coin discriminator where frequencies of eddy currents are measured
Inventor: HOWELLS GEOFF
IPC: G07D5/08
Filed: 2002-11-05
Granted: 2009-01-06
Abstract: A coin processing machine (700) has a coin discriminator (10) operated by a method according to the invention. The coin discriminator measures how an iron coin (40) having an iron core (50) covered by a layer of copper, brass, or bronze affects coil means (20) when the coin is subjected to magnetic fields generated by the coil means external to the coin. Eddy currents induced in the coin are detected by detection means (100) external of the coin. The discriminator (10) induces a magnetic field in the coil means by driving the coil means with time varying drive signals having high frequencies. The coin discriminator receives the iron coin at precise positions in the magnetic field and detects the eddy currents induced in the iron coin by measuring the eddy currents through the coil means. Then, the coin discriminator compares the measured eddy currents with predetermined values for different types of iron coins, and determines the structure, materials and type of the iron coin.
