Patent SE-303486-B (SE)
Inventor: WETTSTEIN A
IPC: C07J1/00
Filed: 1961-07-13
Abstract: The invention comprises D 5-3-hydroxy- or -acyloxy-steroids of the androstane, pregnane or spirostane series containing in the 10-position a hydroxymethyl, acyloxymethyl, formyl, carboxy or carbalkoxy group; and a process for the preparation of any steroid containing a D 5-double bond and the aforementioned 3- and 10-substituents wherein a 5a -halogeno-6b , 19-steroid, a 19,6b -lactone of a 5a  - halogeno - 6b  - hydroxy - steroid 19 - acid or a 19,6b -cyclohemiacetal of a 10-formyl-5a -halogeno - 6b  - hydroxy - steroid is treated with a reducing agent and, if desired, any hydroxy or 10-carboxy compound obtained is esterified or any hydroxy or 10-formyl compound obtained is oxidized and/or any ester obtained is hydrolysed.  The starting material may belong to any of the steroid series mentioned above or to the cholane, cholestane, stigmastane or cardanolide series, and may contain free, ketalized or enolized oxo groups, esterified or etherified hydroxyl groups, alkyl groups of at most 7 carbon atoms or halogen atoms in one or more positions of the steroid nucleus or 17-side chain.  They may also contain double bonds and oxido groups.  When alkali or alkaline earth metals in liquid ammonia are used as reducing agents D 5-19-hydroxy-steroids are formed, and this may be accompanied by the reduction of other oxido groups or of oxo groups unless they have previously been protected. 19,6b -hemiacetals of 5a -halogeno-6b -hydroxy - 19 - oxo - steroids and 19,6b  - lactones of the corresponding 19-acids can be reduced under mild conditions e.g. the use of zinc and an alcohol or an acid, to yield, respectively, D 5-19-oxo-steroids and D 5-steroid-19-acids. These may also be prepared by oxidation of the 19-hydroxy-steroids. The steroids of the invention may further be converted to 19-oxygenated D 4 - 3 - oxo - steroids and these may then be heated with an alkali metal hydroxide in an anhydrous or aqueous solution to give 19-nor - D 4 - 3 - oxo - steroids. Examples are given and an extensive list of esterifying acids is provided.  The 19,6b  - lactone of 3b  - acetoxy - 5a -chloro - 6b  - hydroxy - 17 - oxo - androstane - 19-acid is prepared by chromic acid oxidation of the corresponding 6b ,19 - oxido compound. Specifications 994,764, 994,748 and 994,750 are referred to.

Title: Improved screen
Inventor: ROBERTSON GRAHAM ALEXANDER
IPC: B01D33/00
Filed: 2003-10-20
Granted: 2004-11-24
Abstract: A woven wire cloth screen is described in which at least one fine mesh cloth overlies a coarser mesh backing cloth and an additional coarser mesh cloth is secured over the fine mesh cloth, whose mesh and wire size at least are selected so as in general to prevent relatively large abrasive particles from making contact with the fine mesh cloth. Two fine mesh cloths may be sandwiched between the coarser cloths. In one screen the backing cloth is 30#x01.280 mm diameter S/S wire, the upper fine mesh is 180#x0.030 mm diameter S/S wire, the lower fine mesh is 160#x0.036 mm diameter S/S wire, and the additional top cloth is 30#x60#x0.160 mm diameter S/S wire. A method of making such a screen is described in which the cloths are in turn laid over a rigid frame to which they are to be bonded and the tension in the wire mesh cloths is achieved using pneumatically powered rams acting on clamps which grip the edges of the cloths. All the rams are of the same size and different tensions are imparted to the cloths by supplying air at differing pressures to the rams acting on the different cloths. In particular a method is described for making a woven wire cloth screen which will withstand highly abrasive large particles such as obtained when drilling through Utsira sand, in which a support frame is located in a jig, a coarse backing cloth is stretched over the frame -and secured between clamping jaws along all four edges and then tensioned by moving all the clamps relatively outwardly by pneumatic rams. A fine mesh wirecloth is then stretched over the first cloth and similarly tensioned by means of a second set of clamps and rams. An additional coarse mesh cloth is then similarly stretched over the fine mesh cloth and tensioned by means of a third set of clamps and rams. Thereafter the cloths are secured to the support frame under pressure. After releasing the pressure, opening the clamping jaws, and trimming surplus wirecloth back to the frame, the finished screen can be removed from the jig. A second fine mesh cloth can be laid over the first fine mesh cloth before the top coarse cloth is applied, and the two fine mesh cloths can be clamped using the same set of jaws and rams.
