Abstract: 1,091,091. Grinding. A. S. ROWLEM. Sept. 15. 1966 [Sept. 30, 1965], No. 41500/65. Addition to 885,434. Heading B3D. A machine for sharpening the cutting faces of the teeth of a milling cutter A comprises an arbor B on which the cutter is mounted carried by a frame D supporting a grinding wheel head, the arbor being automatically rotated one tooth after each succeeding grinding operation, and the grinding head being movable to effect a grinding operation by rocking of a quadrant C<SP>2</SP> engaging a rack C<SP>1</SP> affixed to the underside of a table c carrying the grinding head, the quadrant being rocked by a cam 15 on a driving-shaft 1. The grinding head consists of a grinding wheel C driven by a motor C<SP>1</SP> mounted on the table c which is slidable along a guideway d on the machine frame D. The rack C<SP>1</SP> is secured to the underside of the table and is engaged by the quadrant C<SP>2</SP> which is rockable about a stub shaft 6 by rotation of the cam 15 engaging a yoke 16 integral with the quadrant, the cam being secured to the drive-shaft 1. The shaft is driven by a chain drive 4 and freewheel mechanism 3 from a motor 2 and carries a one-tooth sprocket 7 for engaging the teeth of a gear 8 connected by gearing 11, shaft 13 and bevel gears 14 to the arbor B whereby the cutter is rotated one tooth during each grinding operation. During grinding, rotation of the cutter and arbor is prevented by a pawl 18 which engages a ratchet wheel 19 associated with the gear 8 engaged by the one-tooth sprocket 7, the pawl being disengaged from the sprocket when the tooth engages the gear by a cam 21 on the driving-shaft 1. The shaft 1 can be rotated by a handle 5 during the initial setting up, and the arbor B is movable to effect feed of the cutter by rotation of a worm 12 engaging a wheel 12<SP>1</SP> on a screw 24 engaging a nut B<SP>3</SP> on the housing for the arbor whereby the arbor is moved relative to the frame D of the machine. A clutch 23 is disposed between the wheel 12<SP>1</SP> and screw 24 to permit adjustment when, for example, a new grinding wheel is fitted to the machine. In operation, when the drive-shaft is rotated, the cam 15 rocks the quadrant C<SP>2</SP> so that the grinding-wheel is moved towards and away from the cutter to grind one tooth thereof, and after each grinding operation, the cam 21 disengages the pawl 18 to enable the one-tooth sprocket 7 to engage the gear 8 and rotate the cutter one tooth in preparation of the next advance movement of the grinding-wheel.

Abstract: The invention comprises 18, 11-lactones of 11b -hydroxy-9a - X- 20- R1-21-R2-pregnane-18-acids in which X is a fluorine, chlorine or bromine, R1 is a free or ketalized oxo group, or a hydrogen atom and a free or esterified hydroxyl group, and R2 is a hydrogen atom or a free, esterified or etherified hydroxyl group, and particularly steroids of this class having the formula <FORM:0973146/C1/1> and the corresponding D 5-3-ketals, and the 19-nor analogues of all these steroids.  They may be prepared by treating the 18, 20b -lactones of D 4-3-oxo-9, 11b  - oxido-20b -hydroxy-pregnene 18-acids with a hydrohalic acid and then translactonizing the resulting 18, 20-lactones of 9a -halogen-11b -hydroxy-pregnene-18-acids. The 9a -bromo compounds can also be prepared by direct additive combination of hypobromous acid with the 18, 20-lactone of D 4,9(11)-3-oxo-20b -hydroxy-pregnadiene-18-acid Oxidation of the so-formed 20-hydroxy compounds gives the 20-ketones, while treatment with, for example, ethylene glycol and p-toluenesulphonic acid gives the corresponding D 5-3-ethylenedioxy compounds, which may also be oxidized to the 20-ketones. The D 5-3-ketals may be further processed by oxalic ester condensation, iodination and cleavage with sodium acetate into the 18, 11-lactones of D 5-3-ethylenedioxy-9a -halo-11b -hydroxy -20 - oxo - 21 - acetoxy - pregnene-18-acids which on treatment with aqueous perchloric acid in tetrahydrofuran yield the 18, 11-lactones of D 4-3, 20-dioxo-11b , 21-dihydroxy-9a -halo-pregnene -18-acids. By ketalization, reduction with lithium aluminium hydride and ketal cleavage these may be converted to 9a -halo-aldosterones. Detailed examples of all these processes are given.

Abstract: 1,126,025. Modified polymeric polyols and polyurethanes produced therefrom. IMPERIAL CHEMICAL INDUSTRIES Ltd. 5 Oct., 1966 [11 Oct., 1965], No. 42983/65. Headings C3C and C3G. Modified polymeric polyols are obtained by polymerizing, under substantially anhydrous conditions, a polymerizable ethylenically unsaturated monomer in the presence of a free radical polymerization catalyst and a polymeric polyol containing at least 0À7 ethylenically unsaturated groups per molecule. The polymeric polyol may be a polyester, polyesteramide, polyether, polythioether or polyacetal. The ethylenically unsaturated groups may be introduced into the polymeric polyol either by including a suitable ethylenically unsaturated compound in the polymer-forming reaction mixture or by reacting a pre-formed hydroxylated polymer with an unsaturated epoxide. A list of suitable ethylenically unsaturated monomers is provided with styrene or a substituted styrene being preferred. Conventional freeradical catalysts are used. The modified polymeric polyols may be reacted with organic polyisocyanates to produce polyurethanes in the presence or absence of a gas-generating agent, e.g. water or an inert liquid of low boiling point. The example describes the reaction of allylglycidyl ether and oxypropylated glycerol in the presence of BF 3  in diethyl ether, followed by the polymerization of styrene on to the so-formed polymeric polyol in the presence of benzoyl peroxide. The modified polymeric polyol is then reacted with tolylene diisocyanate in the presence of stannous octanoate, triethylene diamine, water and a siloxane/oxyalkylene block copolymer to produce a foamed polyurethane.
