Patent EP-0274265-A2 (EP)
Inventor: BOYINGTON IAN GEORGE
IPC: E21B10/24
Filed: 1987-12-21
Abstract: The invention relates to a drill member and particularly to a so called roller reamer. Roller reamers are known to form part of a drill string whereby to maintain the gauge of a hole during drilling, and known to comprise a number of roller cutters each mounted on the spindle and located in equal spaced relationship around a carrier body. Ordinarily the spindle is mounted in bearing blocks themselves located on a carrier body, and it is known to pack grease around the spindle to minimise wear between the roller cutter and the spindle during use. In use it is known for damage to be occasioned to the bearing box and equally during long usage there can be a loss of lubricant/grease from between the roller cutter and the spindle. The object of the invention is to provide an improved cutter assembly for a roller reamer which objective is met by a construction comprising a cutter assembly for a roller reamer comprising a tubular spindle bearing blocks secured to the ends of the spindle and a rotary cutter rotatably mounted on the spindle characterised by rotary seals 11 between the cutter 9 and the spindle 4 at each end of the cutter, a spring loaded piston 12 mounted within the tubular spindle 4, a passageway 16 through one bearing member 5 communicating with the interior of the tubular spindle 4, valve or nipple means 17 closing the inlet to the passageway 16 and at least one outlet hole 18 through the wall of the spindle 4 communicating with at least one groove 19 extending along the outer face of the spindle 4 over substantially the length of the spindle 4 lying within the   rotary cutter 9.

Abstract: The rotary head (5) pivots about the pin (6) on the support frame (2). When a full reel (12) is in a lower position, the rocking mechanism (22) is brought into an active position. The thread (F) is caught by the grippers (25, 26). The cutter (27) cuts it while the pusher lever (33) pushes the free end of the thread against the flange of the reel (12) where an elastic blade passing through the hole (41) secures it by pressing it against the drum of the reel. <IMAGE>

Abstract: The double metal cyanide complex, e.g. metal hexacyano­metallate, catalysts obtained by reacting metal salts and alkali metal cyanometallates are not easily separated from the reaction mixture because the particle size is too small to allow filtration under normal conditions. Centrifugation, dialysis, or conversion to a filterable metal hydroxide salt are the methods previously described for separating the alkali metal salt formed during reaction from the catalyst. Forming the complex in the presence of an inert filter-aid has been found to give a filter­able catalyst which can be washed clean of the alkali metal salt and can be used without further treatment in the catalysis of the formation of propylene oxide polyols.

Abstract: A process and apparatus for cleaning then coating articles such as circuit board panels with a metallic coating encompasses an enclosed evacuated chamber (125) having a controlled low pressure gaseous process environment. The articles to be cleaned, then coated with a metallic deposit are continuously fed into the enclosed chamber through an air lock mechanism (110) that permits the evacuated chamber to remain at its predetermined pressure and gaseous composition. Included within the chamber are a plurality of transport paths or panel carrying tracks (111). The articles to be cleaned, then coated are continuously transported along the various tracks while being coated. 
     The plurality of tracks (111) are positioned to be substantially parallel with each other so that articles on each track follow paths similar in direction and substantially equidistant from one another. A plurality of bidirectional coating sources are sequentially positioned on both sides of each article transport track so that both sides of the panels are coated.
