Abstract: 420,263. Reproducing foot-sole and other surfaces. MATTHIAS, E., Villa Spelma, St. Moritz, Switzerland. Jan. 20, 1934, No. 2063. Convention date, Dec. 7, 1933. [Class 106 (ii)] Apparatus for reproducing irregular surfaces, for example, the soles of human feet for diagnosis or for fitting footwear or orthopµdic appliances, comprises upper and lower plates 2, 3, mounted in a casing 54 and slidably supporting a number of rows of parallel pins 1. Each pin carries at its lower end a blade 5, one edge of which is parallel to the pin, the other edge being at 45‹ thereto. The blades 5 rest on a perforable sheet 9 supported between upper and lower sets of parallel bars 30, 35, and are lifted therefrom, on closing a cover 49 for the pins, by a plate 40 raised to engage collars on the pins by lugs 41 on the. plate engaging oblique slots 42 in side plates 43 moved laterally by pin and slot connections 46, 52 with the lid. In use the lid 49 is closed to raise the pins 1, a perforable sheet is inserted through a slot 34 between the bars 30, 35, the lid is then opened permitting the blades 5 to descend upon the sheet, and an object, for example, the foot, is pressed upon the surface formed by the pins 1. The blade of each pin pressed on penetrates the perforable sheet and produces a cut, of length corresponding to the descent of the pin, from which the surface of the object may be reproduced by measurement. Records of a foot may be made with the patient in a sitting position (foot unloaded) or standing (foot loaded). To ensure the placing of the foot in the same position on all occasions an upstanding right-angled strip is placed on the plate 2 in fixed relation to the pins 1 and indicators, slidable on the strip, are provided to mark the rear and lateral points of contact between foot and strip.

Abstract: 353,425. Projectiles. HADFIELD, SIR R. A., 22, Carlton House Terrace, London, and CLERKE, A. B. H., Hecla Works, Sheffield. Jan. 22, 1930, Nos. 2243 and 14584. [Class 9 (i).] The base plug or fuze adapter d of an armourpiercing projectile a is screwed into the projectile in advance of the rear face c of the projectile so as to leave a short rear end part a<2> of the wall of the projectile unsupported from within; by this means, should the rear end a<2> of the projectile be subjected to great lateral pressure in passing through an armour plate, it may bend or break without affecting the fuze adapter. The rear end a2 may be made thinner, or may be weakened by a groove a<5>, Fig. 4. The adapter may have a flange d<1>, Fig. 1, at its rear end, or a shoulder n, Fig. 3, at its front end to form a tight joint with the projectile. A ring h, Fig. 3, of brittle material may be screwed into the rear end of the projectile and against a shoulder on the adapter to support the rear end when this is subjected to the propellent pressure in the gun, while not interfering with its freedom of inward movement on impact. To avoid appreciable reduction of the internal explosive charge, the adapter d is made with a recess d<5> in its front end, and may be extended rearwards as shown in Fig. 3. The rear face of the adapter is formed with an annular recess d<3> and a larger screw-threaded recess d<4> to receive the usual coverplate.

Title: A process for introducing a í¸ dienic system into a 3-keto í¸ 19-nor steroid and novel 19-nor-4,9(10) - steroids and process of making them
IPC: C07J7/00
Filed: 1961-01-20
Abstract: The invention comprises steroids of the general formulae: <FORM:0956251/C2/1> wherein R2 represents hydrogen or methyl, R and R1 represent hydrogen and hydroxyl, ethinyl and hydroxyl, vinyl and hydroxyl, methyl and hydroxyl, ethyl and hydroxyl, propyl and hydroxyl, a -hydroxyethyl and hydrogen, and acetyl and hydrogen and the C1 to C6 aliphatic esters of the hydroxy substituted compounds of the first general formula, and a process for introducing a D 4,9(10)-diene system into a 3-keto-D 5(6)-steroid by brominating, e.g. with pyridine perbromide hydrobromide, phenyltrimethylammonium bromide perbromide, or bromine, in the presence of an inert solvent and then removing two molecules of hydrogen bromide from the resulting 3-keto-5a , 10b -dibromosteroid in the presence of a pyridine base or first removing one molecule of hydrogen bromide to form a 3-keto-10b -bromo-D 4-steroid as above, and then removing a second molecule of hydrogen bromide as above to form the desired D 4,9(10)-diene system. A pyridine base may be used as the inert solvent for the bromination reaction which then acts as the dehydrobromination reagent. In the above processes, halogen atoms, hydroxyl groups, keto groups and alkyl groups may be present in the steroid nucleus, e.g., an 11-keto or hydroxy group, a 21-hydroxy group, a 6-methyl or fluoro group, a 16-hydroxy or methyl group, or a 2-methyl group. Suitable inert solvents are carbon tetrachloride, methylene and ethylene dichloride and ethyl acetate. Suitable pyridine bases are pyridine, a -, b - and g -picoline, a -, b - and g -ethyl-pyridine, 2,4- and 2,5-butidine, and 2,4,5-collidine.  In the case where a reactant contains an isolated double bond such as a 17a -vinyl group, bromine also adds onto the isolated double bond to form, for example, a 17a -(1,2-dibromo-vinyl) group, so that an additional step is required to debrominate the isolated double bond after the formation of the D 4,9(10)-system, for example, by means of sodium iodide in acetone. The above processes may be modified in that a product obtained of the above general formula wherein R1 or R contains a hydroxy group is reacted with an acylating agent to form the C1 to C6 aliphatic esters. 17a -Vinyl -19- nor -5(10)- androsten -17b -ol-3-one is prepared by hydrogenating 3-methoxy-17a -ethinyl -19- nor-2, 5(10)- androstadien-17b -ol to form 3-methoxy -17a - vinyl -19- nor-2,5(10)-androstadien -17b -ol and treating this compound with oxalic acid in aqueous methanol. 19-Nor-5(10)-pregnen-20-ol -3- one is prepared by reducing 17b -(a -hydroxyethyl)-1, 3, 5 (10)-estratriene 3-methoxy ether with liquid ammonia and lithium to form 3-methoxy -19- nor -2, 5 (10)-pregnadien -20- ol and treating this compound with oxalic acid in aqueous methanol. 19-Nor-4, 9 (10)-pregnadiene-3, 20-dione is prepared by oxidising the corresponding 20-ol compound.
