Title: New 19-nor-steroids
IPC: A61K31/569
Filed: 1962-03-23
Abstract: The invention comprises steroids of the formula <FORM:0996308/C2/1> (wherein R1 is OH or Oacyl, and R2 is a saturate or unsaturated hydrocarbon radical of at most 4 carbon atoms, or R1 and R2 together are a keto group) and their preparation by splitting off the 3-substituent from a corresponding 3-halo or -sulphonyloxy steroid (wherein the the sulphonyloxy group is an aliphatic, aromatic or araliphatic hydrocarbon-sulphonyloxy group) by reduction.  The product or the starting material, if 17-ol, may be oxidized to the 17-one, which may be reacted with a hydrocarbon metal compound to give the 17a -hydrocarbon-17b -ol. In this, an alkynyl group may be reduced to an alkenyl or alkyl group. 17-ols may be esterified, and 17-esters hydrolysed. Examples are given.  The preparation of the starting materials is described in Specification 996,309.  The 3-unsubstituted steroids of the invention, which are stated to have progestative, gonad-inhibiting and estrogenic activity, may be made up into pharmaceutical compositions with inert carriers.

Title: Improvements in fuel supply systems
IPC: F02C9/16
Filed: 1945-05-10
Abstract: 608,860. Fluid-pressure servomotor-control systems; valves. DOWTY EQUIPMENT, Ltd., DE HAVILLAND ENGINE CO., Ltd., CAREY, F. H., HALFORD, F. B., and MOULT, E. S. May 10, 1945, No. 11780. [Class 135] [Also in Group XXVI] The supply of liquid fuel from a constant delivery pump 20, Fig. 1, to tho burners 35 of a gas turbine is controlled by a lever 51 which regulates the speed of an electric motor 47 driving a ported sleeve 45 within a second ported sleeve 46 driven by the engine to control the flow of fuel through a byepass 38 to the pump inlet 26. Fuel from the inlet side of the pump 20 is supplied by the auxiliary pump 55 to the annulus 53, Figs. 2, 4, in the casing 52 which houses, the sleeves 45, 46. It then passes through ports 59 in the sleeve 46 to an annular space 79 between the sleeves and thence through ports 80 in the sleeve 45 to the longitudinal grooves 81 in the core 82 of the sleeve 45. When the engine speed exceeds that of the motor, the fuel flows out through the ports 62 in the sleeve 46 into the annulus 60 and thence through the pipe 64 to the valve 40 to move the spring-loaded plunger 41 to the right, thus uncovering the annulus 42 and permitting the flow of excess fuel from the burners through the byepass 38 to the pump inlet. When the engine speed is below that of the motor, the fuel flows out through the ports 63 in the sleeve 46 to the annulus 61 and thence through the pipe 65 to the opposite end of the valve 40, thus moving the plunger 41 to the left to cover the annulus 42 and close the byepass. Fuel is supplied by the pump 20 through the pipe 29 and valve 33 to the burner ring 30; each burner 35 of which is connected, through a non-return valve 36 to a collector ring 37 connected to the byepass 38, the valve 36 opening when the . pressure difference at the burner and in the byepass exceeds a predetermined value. A manually-operated emergency fuel cock 39 permits direct flow of excess fuel to the pump inlet from the burners without passing through the valve 40. An emergency speed governor 70 operates a piston valve 34 to control the byepass of fuel through the pipe 75 to the pump inlet. In a modification, the plunger valve 40 is dispensed with and a modified arrangement of ports in the sleeves permits the excess fuel from the burners to pass direct through the sleeves to the pump inlet. In another arrangement, crown-wheels driven in opposite directions by the electric motor and the engine respectively rotate a differential pinion and move it angularly when the motor and engine are out of phase to operate a plunger type valve to control the byepass. Specification 595,152 is referred to.

As shown, when the upper platen 1 of the punching machine reaches its uppermost position a fluid pressure motor 11 is actuated to pivot the lever 8 in the direction of the arrows against the action of a spring 12. The pointed member 13 is slidably mounted in, and variably spring-urged outwardly of, the lever 8. The workpiece is mounted on a spring-cushioned support 4 which is depressed by hold-down 2 until the workpiece contacts a die 5. A sensing device 16, e.g. a selenium cell, following each ejector stops the punching machine if no scrap or blank reaches it. For a punching machine in which at each stroke two circular blanks are cut from strip with minimum waste a separate lever is provided for each of four pieces of scrap resulting from each stroke, three acting at rightangles to the longitudinal axis of the strip and one at an acute angle thereto.
