Patent FR-474906-A (FR)
Inventor: JR JOHN HAYS HAMMOND
IPC: F41G7/00
Filed: 1914-07-09
Granted: 1915-03-26
Abstract: 16,328. Hammond, J. H. July 14, 1913, [Convention date]. Gyroscopic apparatus.-In a method of controlling from a distance the steering of moving bodies, such as torpedoes and torpedo boats, by means of electro-magnetic waves, the moving body is provided with gyroscopic means to maintain a predetermined direction of movement, and means controlled by radiant energy serve to terminate or modify the control of the body by the gyroscope-maintaining means. In the system shown in Figs. 1 and 2, the steering- mechanism is controlled by the piston 23 of a cylinder 22 connected by ports to passages 41, 42 around a ring 36, which is connected by springs 38, 39 to the hull of the vessel. The ring 36 has radial passages 40, 46 which aline with passages 31, 45 in a shaft 25, kept in a fixed position in space by the gyroscope. As long as the vessel maintains the predetermined course, the passages 40, 46 are kept midway between the exhaust ports 47, 48 and the ports 41, 42 connected to the cylinder 22, but when the vessel deflects from its course fluid is admitted to one side or the other of the piston 23, thus adjusting the steering-mechanism. When the controlling-operator wishes to vary the course of the vessel, electro-magnetic waves are transmitted and cause a magnet 7 to admit fluid under pressure from a pipe 12 to cylinders 11, 17. The piston 18 of the cylinder 17 moves a sliding rod 28, which closes the pressure inlet 30 of the passage 31 and disconnects the ring 36 from the shaft 25, thus removing the gyroscopic control from the cylinder 22. In the modified system shown in Figs. 10 and 11, the steering-gear is controlled by the piston 96 of a cylinder 95 connected by passages 100, 101, 102, 103 to ports 91, 92, 93, 94 in a ring 87 surrounding an extension 86 of a shaft 25 kept fixed in space by the gyroscope. The shaft 25 has passages 82, 83 connected to pressure and exhaust, extensions 84, 85 of these passages being kept midway between the ports 91, 92 and 93, 94 so long as the vessel keeps its predetermined course, but, when the vessel is deflected from its course, fluid is admitted to one side or other of the piston 96, thus adjusting the steering-mechanism automatically. The ring 87 is in frictional engagement with the hull of the vessel, and is provided with ratchetteeth 88 whereby it can be rotated in either direction by the cores of solenoids 76, 77, so as to vary the relative position of the ring 87 and the shaft 25, thereby varying the direction in which the gyroscope steers the vessel. The solenoids 76, 77 are selectively controlled by detectors 72, 73 in oscillation circuits tuned to different wave lengths. The controlling-operator can thus adjust the control of the vessel by the gyroscope both as to its direction and amount.

Abstract: The apparatus for sealing face plates (753) and cathodes (754) has three stations (701, 702, 703). The first (701) is a preheater, the second (702) is an alignment and irradiation station and the third (703) is controlled cooling station. Beneath each station, a vacuum pump (710) capable of drawing ultra-low pressures is provided. The preheater is equipped with upper and lower banks of radiant heaters and reflectors (712). The upper heaters are provided above a quartz window (713) if a chamber (714) constituting the station. The pressure in the preheater is pumped down to that in the alignment and irradiation station prior to opening of the gate valve between them and transfer of the face plate and cathode. At the alignment and irradiation station, further heaters (716) are provided. Those above the face plate and cathode, the face plate being uppermost, are mounted on frames (717) about hinges (718), whereby they can be swung up to clear this station's to quartz window, exposing the face plate to the view of an optical system (719) and a laser (720). Manipulation controls (722) are provided for manipulating the position of the face plate to be in pixel alignment, as measured by the optical system (719), with the cathode. The laser is traversed around frit between the face plate and the emission device to cause the frit to melt into contact with both and freeze off once the laser has traversed further. The cooling station (703) has meanwhile been pumped down and the sealed device is transferred to it. The temperature of the device is allowed to rise very slowly, in order to reduce the risk of thermal cracking to as great an extent as possible. As the temperature slowly falls, air is slowly introduced, so that the finished device can be removed to the ambient surroundings.

Title: Method and apparatus for connecting a lateral branch liner to a main well bore
Inventor: OHMER HERVE
IPC: E21B17/00
Filed: 1999-11-19
Abstract: A method and apparatus for establishing connectivity of lateral branch liners to main well casings to achieve predictable and stable mechanical connectivity at the lateral junction of branch well bores to the main well bore to counter the problems of formation instability at the junction. After construction of a well having one or more lateral branches, a retrievable lateral branch template is located in the casing of a main well bore in positioned and oriented registry with a casing window that opens to a lined lateral branch. A retrievable lateral branch connector is then installed in assembly with the template to cooperatively define a production flow path having maximized mechanical integrity and optimized production flow in both the lateral bore and the main bore. The lateral branch template and connector provide the capability to selectively re-enter a lateral branch and to also hydraulically isolate the formation surrounding the junction from fluid circulating in both the lateral branch and the main well bore. Both the lateral branch template and the lateral branch connector are prefabricated and installed into the well by means of running and setting tools. Electrical power or hydraulic pressure conductors incorporated in the template and connector assembly may be used to provide for production operation and control of main and branch well bore production after installation. The equipment can be deployed in wells constructed with any inclination and orientation and can accommodate low or high dogleg severity at kick-off.
