    摘要: A device for use with a retrievable bridge plug (30) comprising an upper packer element (3) and a lower packer element (11). The upper element (3) is connected to an upper link (6), which can rotate around a first pin (5). Upper link (6) is rotatably connected to a lower link (8) by a second pin (7). Lower link (8) can rotate around a third pin (9). An angle (&agr;) is formed between the longitudinal axis of the bridge plug and a line extending through the first pin (5) and the second pin (7), and correspondingly through the second pin (7) and the third pin (9), which is greater than zero when upper link (6) and lower link (8) is drawn. Upper link (6) and lower link (8) are arranged for, at setting, to expand radially by compression of upper packer bracket (3) against lower bracket (12), for forming a mechanical barrier for upper packer element (3) and lower packer element (11).

    摘要: A retrievable well plug has a through shaft (12) with link connections (62, 64) and a packer element (66). By pushing the link connections (62, 64) and the packer element towards each other, the link connections (62, 64) and the packer element (66) expand radially, such that a mechanical barrier for the packer element (66) is formed. The links (76; 174, 176) have a generally T-shaped cross sectional profile and include an arm (78) with an end (80) meant for fastening to the fastening devices (72, 74). The other end of the arm (78) fastens to the second link (77) of the link connection (62, 64). Upper supporting surfaces (84, 86; 184; 192, 194) of the links (76; 174, 176) form an approximately tight mechanical barrier against the packer element (66) in an expanded position. The anchoring device (20) has a number of gripping devices (22), wherein the gripping devices (22) at setting of the well plug (10) expand radially, thereby providing an anchoring of the well plug (10) to the well bore wall.

    摘要: By modern gears for electric/hydraulic and manually driven sheet winches, demands are made on the presence of a free- wheeling mechanism (24) in case that the drive unit fails, and it is also desirable that the gear takes up as little space as possible, irrespectively whether it is placed on deck or below on a boat. Thus there is indicated a gear of the kind indicated which is peculiar in that the planet carrier (22) is suspended on roller/ball bearings disposed farther away from the centre axis (12) of the planet carrier than the free-wheeling mechanism (24). This design enables reducing installation dimensions for the gear, as the normally used central shaft may be omitted and the space can be utilised for placing the free-wheeling mechanism (24).

    摘要: A bridge plug (1) for use in a casing (7), for example in oil and/or gas wells, comprising a packing element (2) of a resilient material is disclosed. The packing element (2) is adapted for at impact from a running tool to expand from a first diameter, to a second diameter that is greater than the first diameter which corresponds to the inner diameter of the casing that is to be sealed. The packing element (2) is divided in zones forming at least one expandable sealing packing element (34, 35) and at least one expandable support packing element (31, 32, 33), where the support packing elements (31, 32, 33) are expandable to a smaller diameter than the sealing packing elements (34, 35). The bridge plug (1) is further comprised of an anchoring means (3) that is provided for holding the bridge plug (1) in its place in the casing by a friction surface (28) that is pressed radially against the casing (7).

    摘要: For some powered drum winches, e.g. in sailing boats, it is desirable that the drum can be driven with two different speeds. Basically, this is no technical problem, but it has been difficult to achieve both a high efficiency and a simple construction. It has been proposed that with the use of a plural shaft gear an advantageous result is obtainable in making the gear drive the drum with two different speeds based on a reversible driving motor being driven in one or the opposite direction. This control principle is also used in the present connection in which, however, it is disclosed how the relevant gear can be designed in a compact and inexpensive manner about only a single gear shaft.
