Title: Fluid-actuated impact drilling tool
IPC: E21B4/14
Filed: 1975-05-29
Abstract: 1515921 Boring earth &c. BASSINGER TOOL ENTERPRISES Ltd 29 May 1975 [14 June 1974] 23386/75 Heading E1F A fluid-actuated impact drilling tool for use in rotary drilling comprises a housing 26, 28, 60 adapted to be connected at 22 to a string of drilling pipe, a bore 24 within the housing capable of allowing fluid e.g. drilling mud to flow from the drilling pipe through the housing, a valve member 32 slidable within the bore 24, and a hammer 88 slidable within the bore 24 independently of the valve member 32. When fluid is passed down the bore 24, a pressure differential exists between the fluid within the bore and the pressure outside the housing. By virtue of passages 44, 47 and 76, 80, the pressure differential will act on pressure surfaces on the valve member 32 and the hammer 88, these pressure surfaces being enclosed by seals 46, 48 and 66, 72 respectively. Since the respective lower seals 48, 72 enclose a larger area than the upper seals 46, 66, the valve member 32 and hammer 88 move upwardly, the latter more slowly than the former due to its greater weight. The valve member 32 has a central bore 50 so that when the upper end of the hammer 88 reaches the lower end of the valve member, it enters the bore 50 and the downward flow of fluid is substantially interrupted. The back pressure thus developed in the upper part of the bore 24 hurls the valve member 32 back to its lowest position, at a seat 59, and then drives the hammer down with great force. The hammer may hit an anvil 150 one end of which is slidable in the bore 24 whilst the lower end is connected to a drill bit at 176. The cycle of movement is then repeated. A central bore 104 in the hammer 88 is closed at the top by a plug member 94 which rests on a shoulder 100 and may be withdrawn by hooking the end of a line to undercuts 114. A removable orifice member 112, which rests on a shoulder 108 within the plug member 94, has an orifice 106 to control the amount of leakage of fluid past the valve member 32 and the hammer 88. Different sized orifices 106 can be used to suit the working conditions. A hammer catcher 144 fits around flanges 136 and 162 on the hammer 88 and anvil 150 respectively, so that when the drill bit is raised and the anvil moves downwardly relative to the housing, then the hammer is also pulled downwardly and held in its lowermost position, thus preventing operation of the tool. Annular rings 54 and 90 provided in the valve member 32 and hammer 88 respectively, and the orifice member 112, are made of corrosion-resistant material e.g. carbide steel.

Title: Immuno-suppressive agent bredinin
IPC: C07H19/052
Filed: 1973-05-17
Abstract: 1363622 The antibiotic bredinin TOYO JOZOKK 17 May 1973 23601/73 Heading C2A The novel immunosuppressive antibiotic bredinin, (i.e. anhydro - 4 - carbamoyl -5- hydroxy - 1 - ribofuranosylimidazolium hydroxide) having the formula is produced by aerobically cultivating Eupenicillium brefeldianum (NRRL 5734) in an aqueous nutrient medium containing assimilable sources of carbon and nitrogen and then isolating the bredinin from the culture medium. The cultivation is preferably carried out by submerged aerated deep culture at 26-30‹ C. for 40-70 hours. The antibiotic is obtained from the culture medium by filtering off the mycelium, adjusting the pH of the filtrate to pH 9 and adsorbing the antibiotic therefrom on a strongly basic anion exchange resin in the -OH form. The antibiotic is eluted with 2% aqueous acetic acid, again similarly adsorbed and eluted and the eluate then concentrated in vacuo and the oily residue is triturated with methanol and acetone to give crude bredinin as a grey powder. This product is purified by chromatography of its aqueous solution on a silica gel column, and collecting the violet-coloured fractions, which are treated with H 2 S to precipitate chelated metals, filtered and dried in vacuo. The powder is dissolved in pyridine-acetic acid buffer, the solution purified over cross-linked DEAE- dextran gel and pure bredinin is crystallized from the eluate by adding methanol. Bredinin has weak activity against tumours and Candida albicans, no antibacterial activity, and strong immunosuppressive and antiviral activity.
