Abstract: A safety valve which may be installed on an offshore wellhead above the tubing head and below the Christmas tree. The valve has a housing (12) with upper and lower vertical passages (32) and a lateral housing passage (16). A cylindrical gate (30) is disposed within the lateral passage (16) and includes a "T" shaped passage therein. The gate (30) may be moved laterally and angularly within the lateral passage (16). During completion or workover of the well, the gate (30) is moved laterally until the upper and lower vertical passages (32) are in full open communication to run drills, hangers or other large diameter devices into the well via a BOP which may be attached to the top of the housing. During normal production, the gate (30) may be laterally moved into the intersection of the vertical (32) and lateral (16) passages and the small through head part of the "T" passage serves to provide a vertical flow path through the production bore which is sealed off from the larger upper and lower vertical passages (32). Flow through side outlets in the housing is possible through the base of the "T" passage. The gate (30) may be angularly moved to have production to the lateral outlets via the head part of the "T" when the base part of the "T" is aligned with production tubing. Should the need arise, the valve may be angularly rotated to a position where the fluid flow path of the production tubing is completely shut in.

Title: Multi-step conveyor comprising a loading station, a vertical conveyor and a dispensing device for bulk material
IPC: B65G67/60
Filed: 1985-01-04
Granted: 1987-05-06
Abstract: A multi-stage conveyor system consists essentially of a loading unit for loose material to be conveyed, an elevator unit and a transom unit for conveying the material to a depositing station. When transferring the material from the elevator unit to a delivery branch of a standard belt, abrasive action on the material by throwing the same and the resulting development of dust are avoided. The conveying conditions comprise changing the position of legs defining an opening angle between the elevator unit and the delivery branch. An elevator belt bearing, as receptacles for the material to be conveyed, receptacles such as boxes or chambers passes through the elevator unit and into a terminal branch in a region of changing the direction of belt travel in a bending reach about a central swivel axis. An open side of the chambers on the elevator belt is covered by the standard belt during travel through the elevator unit and the bending reach about the swivel axis. In the bending reach the standard belt takes over the function of conveying the material to the depositing station. A multi-fulcra linkage system has one of its fulcra on the swivel axis, and changing of the configuration of the linkage system causes an angular displacement between the elevator belt terminal branch and the standard belt delivery branch.

Abstract: A seal for an internal combustion engine having a fuel injection nozzle positioned within a stepped bore formed in a cylinder head. The fuel injection nozzle contains an exterior stepped configuration with a shoulder formed between its steps. The seal includes a ring circumferentially positioned around and contacting the smaller diameter portion of the fuel injection nozzle. The ring has a flat first end which abuts the shoulder of the fuel injection nozzle and a tapered second end which contacts the smaller diameter portion of the stepped bore. The taper is formed on an exterior surface of the ring and has a maximum outside diameter which is slightly larger than the smaller diameter portion of the stepped bore. The seal also contains an outwardly projecting bulge formed between the first and second ends. The bulge permits the first and second ends to move axially relative to one another as the fuel injection nozzle is axially adjusted within the cylinder head and during normal engine operation. The seal serves to prevent combustion gases, which are generated in the cylinder, from flowing into the larger diameter portion of the stepped bore.

Title: Method and device for producing a wire link band
IPC: B21F43/00
Filed: 1986-09-03
Granted: 1989-08-09
Abstract: There is described a method and a device for the production of a wire jointed-band of alternately clockwise and counterclockwise, respectively, wound spirals of metal wire or artificial resin wire, wherein the spirals are guided to a narrow pass such that the windings providing the spirals open themselves in the area of the narrow pass and in this the parallel spirals partly are pushed into each other such that in each case one of the windings of one spiral is placed between adjacent windings of the adjacent spiral whereby the spirals thus fitted into each other are connected with each other by inserting a coupling wire into the space provided by the overlapping windings and whereby in each case several of the pairs of spirals fitted into each other are guided to the narrow space in which area the spirals are driven in the transporting direction. This is resulting in a high production speed and broad wire jointed-bands.
