Title: Circulation tool with valve operated by dropped ball
Inventor: CARMICHAEL MARK
IPC: E21B21/10
Filed: 1999-02-25
Abstract: A circulation tool (1) for use in a well riser consisting of one or more valve members (9) and having a radial outlet providing passages (7) for drilling fluid. The valve member being actuated by a ball (15, fig. 2) dropped down the shaft to temporarily block the passage way and hence build up fluid pressure until shear pin (14) breaks and the valve moves to a position obscuring the passages (see fig. 2). Flow through the tool is maintained by inlets (13) in the valve member. Filters can be provided on the exterior of the passageways to prevent the ingress of dirt into the tool. The tool can also be fitted with an additional sleeve (31, fig. 3) around the outer surface with nozzles (33, fig. 3) to expel fluid tangentially and rotate the sleeve to aid in cleaning the bore.

Title: Growing mussels on pinned rope : inserting pins through rope
Inventor: SMITH JAMES
IPC: A01K61/54
Filed: 1999-03-11
Abstract: To form a pinned rope to which mussels will attach themselves and grow, a rope is passed through a device where it is clamped at 60 and clamped and rotated at 140 to untwist rope strands between the clamps, allowing for a pin to be inserted through the rope, whereupon the strands are allowed to re-twist to secure the pin. This process is repeated along the rope. The clamping and rotation are carried out-by the rotation of one lever.

Title: Method of foam molding
Inventor: NARISAWA TSUNEO
IPC: B29C43/00
Filed: 1982-01-27
Abstract: PURPOSE:To obtain efficiently a molded item the state of the surface of which is good and which can be thined and has a foamed layer therein and a non- foamed layer on the surface, by carrying out molding under reduced pressure using molds with a specific structure. CONSTITUTION:In the process where a molten resin is introduced through a sprue 1 into the molds, and is flowed through a runner 2 and a gate 3 into a cavity 4 where it is allowed to cool to set, the pressure in the molds when the injection molding is carried out is kept at a low level by an airtight structure comprising a groove 6 round said sprue 1, runner 2 and cavity 4 and a packing 7 situated in the groove 6 and a glass withdrawing groove 8 situated between said packing 7 and said cavity 4 and enclosing said cavity, said runner 2, said gate, and said sprue 1. EFFECT:As the pressure in the molds is in the reduced state, the flow of the resin is improved, and the molding cycle is shortened to improve the productivity. Even a small-sized vacuum pump can be used to reduce the pressure.
