    Abstract: A system for tethering a subsea blowout preventer (BOP) or well head is disclosed. In at least one embodiment, the system comprises an interface associable with the BOP, and more than one anchors disposed about the BOP. Each anchor is configured to carry or support a tensioning system arranged in operable association with a respective tether. Each tether is arranged so as to link a respective anchor with a respective operable means associated with the BOP. Furthermore, each of the respective operable means are configured in operable association with the interface such that tension in the tethers can be adjustable either individually or together as a group of two or more tethers, by way of the interface.

  • Publication number: 20220085672
    Abstract: A rotor (3a . . . 3c) for an electrical machine (1) is described which comprises several rotor segments (10a . . . 10c, 10a?, 10a?, 10 . . . 10??) which are arranged successively along the rotational axis (x) of the rotor (3a . . . 3c) and each comprise a rotor plate (11) or several rotor plates (11). Magnetic poles (A . . . D) of two adjacent rotor segments (10a . . . 10c, 10a?, 10a?, 10 . . . 10??) are twisted relative to one another around the rotational axis (x) of the rotor (3a . . . 3c) by a staggering angle (?), wherein the staggering angle (?) is smaller than a polar angle (?) lying between two magnetic poles (A . . . D) of a rotor segment (10a . . . 10c, 10a?, 10a?, 10 . . . 10??). The rotor (3a . . . 3c) comprises at least two first cutouts (12) which are arranged on a first hole circle (L1) around the rotational axis (x) of the rotor (3a . . . 3c) and are each twisted relative to one another by an angle (?) which corresponds to the polar angle (?) minus or plus the staggering angle (?).

  • Publication number: 20100180982
    Abstract: The silo safety system implements safety logic for silo opening gates by utilizing light sensors connected to a programmable logic controller or equivalent configuration of relay contact switches. Photodetection sensors and their associated light transmitters are placed on opposing lateral sides along a truck passageway under the silos where the tail, middle, and front of a truck are presupposed to be. When a truck pulls under the silos, system logic uses the resultant pattern of beam breaks to prevent the silo gates from opening unless the truck cab is clear from the silo that the truck is supposed to be under. For two or more silos, the system enables only the correct silo, while the other silos are disabled. The silo that the truck is under can then only be energized by the silo control operator. The control logic can have a default configuration for a predetermined truck size.

  • Publication number: 20070183346
    Abstract: A mobile router is configured for attaching to a selected router in a clustered network (e.g., a mobile ad hoc network) based on identifying a network topology model of the clustered network from received router advertisement messages that include tree information option fields specifying attributes of the network topology model. The mobile router selects which router advertisement originator to attach to based on correlating the attributes of the router advertisement originators relative to identified priorities, and orders the router advertisement originators within a default router list based on the identified priorities. If the mobile router detects a router from a second clustered network, the mobile router advertises to the attachment router that the second clustered network is reachable, enabling the two clustered networks to communicate using a point-to-point link between the respective attachment routers.

  • Publication number: 20030055495
    Abstract: Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery using a catheter, and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes. The stents may include an annulus section, a sinus section with the membranes attached over sinus apertures, and an outflow section. Lockout tabs and making slots secure the stents in their expanded shapes. Alignment structure ensures concentric unfurling of the stent. Anchoring elements at the stent edges or in the stent body secure the valve within the annulus. A method of manufacture includes shape setting the sheet-like stent to ensure an outward bias during deployment. The stent may also include dear tracks for engagement with a gear mechanism for deployment.

  • Patent number: 5555897
    Abstract: The invention provides an apparatus and method for manipulating parts of the body in surgical procedures, particularly useful for peritoneal distension in laparoscopic surgery. The apparatus comprises a positionable support structure having an extendible horizontal arm rotatably mounted to an extendible vertical post, the post having a clamp at its lower end for mounting to a surgical table. An end segment at the distal end of the horizontal arm has a mount for mounting end-of-arm tooling, for example, peritoneal distension instruments. Locking mechanisms are disposed in the horizontal arm, vertical post and end segment to lock the support structure in a desired position. A motor is disposed within the vertical post for power-assisted extension and retraction of the vertical post. Preferably, the locking mechanisms and motor are controllable using switches mounted on the end segment.

  • Patent number: 4822357
    Abstract: An auxiliary artificial heart which comprises a pump having a single opening that is connected to the aorta and is operable in synchronism with the heart of the patient to assist the normal function of the heart. The auxiliary artificial heart comprises a housing having the single opening therein and a diaphragm which is movable toward and away from the opening by a rotating reversible electric stepping motor. Rotation of the motor rotates circumferentially spaced roller pins which extend radially inwardly into engagement with a helical groove of a screw attached to the diaphragm such to translate the screw and move the diaphragm toward and away from the opening. The housing is sealed to enclose a gas in the housing such that the differential pressure caused by movement of the screw assists the diaphragm in its movement.
