Patent CA-2139415-A1 (CA)
Title: Ratio change control method and related gear transmission device, in particular for a vehicule
Inventor: ANTONOV ROUMEN
IPC: F16D43/10
Filed: 1993-07-02
Abstract: PCT No. PCT/FR93/00674 Sec. 371 Date Jan. 3, 1995 Sec. 102(e) Date Jan. 3, 1995 PCT Filed Jul. 2, 1993 PCT Pub. No. WO94/01696 PCT Pub. Date Jan. 20, 1994.A transmission device including a planetary gear train with a ring gear connected to the input, and a sun wheel counter-rotationally locked by a free-wheel. A planet carrier is connected to the output shaft. The ring gear and the planet pinion carrier my be coupled via a clutch which is compression-actuated by fly-weights to ensure direct drive. When the clutch is released by an axial thrust caused by the helical gearing and countering that of the fly-weights, the sun-wheel is immobilized by the free-wheel and the device operates as a reducing mechanism. The planetary gear train is arranged as an oil pump delivering through a duct and through the stack of clutch discs. When the clutch is actuated by the fly-weights, the delivery path is closed off, and the meshing motion between the gears forming the oil pump tends to be eliminated as a result. Therefore, the frictional process of the discs need only immobilize the gears to achieve direct drive. Ratio changes may be made more flexible, and clutch wear and heating may be reduced.

Title: Modulated bias unit for rotary drilling
Inventor: BARR JOHN DENZIL
IPC: E21B7/06
Filed: 1995-06-01
Abstract: A modulated bias unit, for controlling the direction of drilling of a rotary drill bit when drilling boreholes in subsurface formations, comprises a number of hydraulic actuators spaced apart around the periphery of the unit. Each actuator comprises a movable thrust member which is hydraulically displaceable outwardly and a formation-engaging pad which overlies the thrust member and is mounted on the body structure for pivotal movement about a pivot axis located to one side of the thrust member.  A selector control valve modulates the fluid pressure supplied to each actuator in synchronism with rotation of the drill bit so that, as the drill bit rotates, each pad is displaced outwardly at the same selected rotational position so as to bias the drill bit laterally and thus control the direction of drilling.   The pivot axis of the formation-engaging member is inclined to the longitudinal axis of rotation of the bias unit so as to compensate for tilting of the bias unit in the borehole during operation.

The rotor is equipped with cylindrical rollers (5) in recesses (4), which rollers can move between an extended and a retracted position. Part of the drilling mud that flows through a central conduit (10) in the rotor, passes through inlet ports (9) and the recesses into chamber-parts (6a) and pushes rollers (51) into their extended position and in a clockwise direction, making the rotor turn, whilst drilling mud of lower pressure is pushed from the corresponding chamber-parts (6b) through the outlet ports (7) into the annulus (8) between the motor and the borehole wall. When the rollers (51) reach the wing deflector cams (2) they are forced into the retracted position, their tasks being taken over by rollers (5).

IPC: B65B5/06
Filed: 1994-07-06
Abstract: Des produits en vrac, par exemple des produits alimentaires gluants, sont divisés en petites portions individuelles avant leur passage dans un poste de pesage (20). Par la suite, on les regroupe pour former des portions plus grandes ayant, par exemple, un poids prédéterminé. Selon le mode préféré de réalisation de ce système, on utilise une chaîne sans fin de bacs transporteurs (12) défilant, sur deux lignes droites, au-dessus d'un certain nombre de récipients (22) dans lesquels ils déchargent de manière sélective leur contenu après leur passage dans le poste de pesage. Un dispositif distributeur (14, 18) est monté devant ce poste et au-dessus d'un tronçon horizontal de la chaîne où celle-ci fait demi-tour, et il introduit les produits dans les bacs en évitant tout chevauchement. On décrit divers modes avantageux de réalisation des pièces individuelles du système, et notamment d'un poste de pesage spécial permettant l'exploitation du système avec un rendement suffisamment élevé. Le système est utilisable à des fins de triage ou dans la formation de portions de produits selon des principes de dosage ou de pesage combiné.
